The majority of vannamei shrimp aquaculture activities are carried out intensively with very high stocking densities, leading to a decline in water quality and triggering a series of disease outbreaks. Vibriosis disease outbreaks due to poor aquaculture environmental conditions are characterized by accumulated waste loads. Identification of the causative agents of vibriosis is crucial to ensure disease diagnosis and appropriate therapy as a preventive strategy for vibriosis disease and to maintain production stability. Based on the results of Vibrio sp. bacterial colony counts from 14 observed vannamei shrimp ponds, 6 shrimp ponds still show counts above the maximum threshold of ≥1.0x103 cfu/ml according to the quality standards set by the Ministry of Marine Affairs and Fisheries. However, if the density of Vibrio sp. bacteria reaches 104, it will cause massive shrimp mortality in aquaculture ponds. This is undoubtedly influenced by the water quality of the observed ponds, which remains stable or non-fluctuating and optimal for vannamei shrimp aquaculture activities.

Renewable energy is a global concern and should be incorporated into education to raise awareness among younger generations, including in physics education. Educators have made various efforts to raise awareness of the importance of pursuing renewable energy. A breakthrough sought in this research is to incorporate collaborative learning into the science-technology-engineering-art-mathematics (STEAM) approach. Integrating STEAM into collaborative learning can simultaneously develop critical and creative thinking skills by exploring local resources to become renewable energy sources. The research involved 36 high school students who met the criteria for having a smartphone and accessing a reliable internet connection. These conditions are designed to facilitate students' producing essays and posters exploring renewable energy sources in their local area. The research design employs a one-group pretest-posttest approach to assess the effectiveness of this STEAM-based collaborative learning process. The data collected from tests that have undergone t-tests and N-gain analysis, triangulated with observation data and questionnaires, illustrates the progress made in improving students' critical and creative thinking abilities. In conclusion, the implementation of STEAM-based collaborative learning demonstrates the highest level of achievement in creative thinking. It enables the production of innovative mini-projects that critically analyze local resources available for national energy sources.

Abstract Poor dietary intake of vitamin B12 and folate before and during pregnancy has been associated with adverse birth outcomes. This relationship has not been rigorously evaluated in Tanzania. We performed secondary analyses of data collected during the perinatal study, a double‐blind trial that investigated the effect of vitamin supplements on perinatal outcomes in Tanzania between 2001 and 2004. In this analysis, we used log‐binomial models to investigate the adequacy of vitamin B12 and folate intake among 7633 mothers and the association of vitamin B12 and folate intake during pregnancy with low birth weight, preterm birth (PTB), small for gestational age and foetal death. Sixty‐seven percent of women had vitamin B12 intake below the recommended dietary allowances (RDAs) of 2.6 mcg for pregnant women, and 98% of women had folate intake below the RDA of 600 mcg for pregnant women. Compared with women in the lowest tertile of vitamin B12 intake women in the highest tertile were 26% less likely to have PTB (relative risk [RR] = 0.74, 95% confidence interval [CI]: 0.65, 0.84) and 36% less likely to have severe PTB (RR = 0.64, 95% CI: 0.50, 0.83). Compared with women in the lowest tertile of folate intake women in the highest tertile were 21% less likely to have PTB (RR = 0.79, 95% CI: 0.69, 0.89) and 21% less likely to have severe PTB (RR = 0.79, 95% CI: 0.69, 0.89). The provision of an adequate supply of these nutrients before and during pregnancy would improve pregnancy outcomes in Tanzania.

Weeds are among the limiting factors that influence low production of economically important crops including cashew (Anacardium occidental L.). Shrub weeds attribute to inter-competition for resources, hinder harvesting and ultimately reduce cashew yields in Tanzania. The current study determined the distribution, characteristics and chemical control option of Dichapetalum Engl in Lindi and Mtwara regions, Southeastern Tanzania. The distribution study involved a survey for weed presence along the areas of Lindi and Mtwara regions. The characterization included distilling, and assessing the growth and development properties of shrub weed. Chemical herbicides; glyphosate 480g. ai/l, 2, 4 D - Dichlorirophenoxyacetic 720g. ai/l, triclopyr 160g a.i./l and 1:1 mixture of glyphosate 480g a.i./l plus triclopyr 160g a.i./L at 15, 20 and 25 mls of formulated product/L of water per 4 m2 were tested on tender, mature and blooming growth stages of D. Stuhlmannii and three spraying frequencies. Findings revealed that the D.stuhlmannii, is a widely distributed shrub weed in Lindi and Mtwara regions. The weed was characterized with three main growth stages of seedling, mature and blooming with a long tap root and evergreen throughout the wet and dry seasons. The tested herbicides revealed the potential suppression of D. Stuhlmannii growth. Glyphosate and a mixture of glyphosate + triclopyr at 15 ml/L outperformed triclopyr and 2, 4 D across all the growth stages. Double spraying of glyphosate and its mixture bettered frequencies of triclopyr and 2, 4 D. The delayed regrowth of suppressed shrub weed took 90–120 days after application of herbicides. The current study recommends for single or double applications of glyphosate herbicides at 15 ml/L or 10,700 ml/ha on tender or mature D. Stuhlmannii in cashew farms. Further studies on the economic feasibility and effect on the microbiota of applied fungicides are required.

Cultivators who manage catfish farming businesses must consider the possibility of low production yields caused by both external and internal variables. The risks that catfish farmers confront may be to blame for the low output. The aims of this study were to determine the source of production risk and the level of risk correlated with catfish production. The method of determining the area of study is carried out intentionally (purposively). This research method is a descriptive and analytical method. The snowball sampling approach was used with a sample of 40 respondents. The data used is a combination of sources both primary and secondary. The analysis used includes variance, standard deviation, coefficient of variation, and risk level based on the risk map. Pests and diseases, weather and climate, the quality of catfish seeds, water quality, cannibalism, and human resources or cultivators who carried out the catfish cultivation process are all factors of production risk in Kediri Regency. The level of risk of catfish production is high, based on the variance value of 21.03, standard deviation of 4.59, and coefficient of variation of 1.61, while the production risk map reveals that the production risk faced by farmers is in the yellow zone, therefore it is included in the high-risk category.

Abstract Background HIV prevalence in Tanzania is still high at 4.7% among adults. Regular HIV testing is consistently advocated in the country to increase the level of awareness of HIV status, thus contributing to national HIV prevention. We report findings from three years of implementation of an HIV Test and Treat project utilizing provider-initiated and client-initiated testing and counselling (PITC and CITC). This study compared the effectiveness of PITC versus CITC in HIV case detection by the different departments of health facilities. Method This retrospective cross-sectional study used health facility-based HIV testing data collected from adults aged 18 years and above between June 2017 – July 2019 in the Shinyanga region, Tanzania. Chi-square and logistic regression analysis were used to assess determinants of yield (HIV positivity). Results A total of 24,802 HIV tests were performed of which 15,814 (63.8%) were by PITC and 8,987 (36.2%) by CITC. Overall HIV positivity was 5.7%, higher among CITC at 6.6% than PITC at 5.2%. TB and IPD departments had the highest HIV positivity 11.8% and 7.8% respectively. Factors associated with a positive test were testing at a department in the facility compared to CITC, first-time test, and being or having been married compared to being single. Conclusion Success in identifying HIV + patients was highest among people visiting the clinic for HIV testing (CITC) and first-time testers. With PITC, HIV + patient detection differed between departments, suggesting divergent risk profiles of respective clients and/or divergent HIV alertness of staff. This underscores the importance of increased targeting for PITC to identify HIV + patients.

BackgroundWomen's empowerment is one critical pathway through which agriculture can impact women's nutrition; however, empirical evidence is still limited. We evaluated the associations of women's participation, input, and decision-making in key agricultural and household activities with women's diet quality.MethodsWe analyzed data from a cross-sectional study of 870 women engaged in homestead agriculture. We used food frequency questionnaires to assess women's diets and computed women's diet quality using the Prime Diet Quality Score (PDQS) (range 0–42), which captures healthy and unhealthy foods. We evaluated women's decision-making in 8 activities, food crop farming, cash crop farming, livestock raising, non-farm economic activities, wage/salary employment, fishing, major household expenditures, and minor household expenditures. Generalized estimating equations (GEE) linear models were used to evaluate associations between (a) women's participation, (b) decision-making, (c) adequate input, (d) adequate extent of independence in decision-making in agriculture, and (e) adequate input in use of agricultural income with their PDQS. Adequate input was defined as input into some, most or all decisions compared to input into few decisions or none. Adequate extent of independence was defined as input to a medium or high extent compared to input to a small extent or none.FindingsMedian PDQS was 19 (IQR: 16–21). Women's adequate input in decision-making on wage and salary employment (estimate: 4.19, 95% CI: 2.80, 5.57) and minor expenditures were associated with higher PDQS vs. inadequate input. Women with independence in decision-making on livestock production (estimate: 0.97, 95% CI: 0.05, 1.90) and minor household expenditures, and women with adequate decision-making in the use of income from wages/salaries (estimate: 3.16, 95% CI: 2.44, 3.87) had higher PDQS. Participation in agricultural activities was positively associated with PDQS.ConclusionsWomen's participation and input in decision-making in wage and salary employment, livestock production, and minor household expenditures were strongly associated with the consumption of better-quality diets. Women participating in multiple farm activities were also likely to have better diet quality. This study adds to the growing evidence on the pathways through which women's empowerment may influence women's nutrition in rural Tanzania.

Land valuation is a critical component of the cadastral system, closely linked to land use and management. The value of land is typically assessed based on the benefits it offers. The high land prices often observed in urban areas result from increased demand, whereas the availability of land remains fixed. Several methods can be employed for land valuation, including the market comparison method, the income capitalization method, and the cost method. This study focuses on the income capitalization approach for determining land value. According to this method, higher income generated from a property leads to a higher property value. For residential properties, income is derived from net rent, calculated as rental income minus operational expenses, using the income approach. This research employs geostatistical analysis to model land values. The mathematical model developed through geostatistical analysis aims to represent actual land values accurately and facilitate the establishment of land value zones.

Due to their individual shape, form, texture and colour variations, the automatic extraction of a building from high-resolution aerial photographs continues to be complicated. The Mask Region-based Convolutional neural network (Mask R-CNN) has shown recent improvements in object detection and extraction for updating data, which are superior to other methods. In this paper, a dataset consisting of aerial photography images acquired by aircraft in the urban and educational area of Institut Teknologi Sepuluh Nopember Surabaya to explore the potential of using Mask R-CNN, the art model, for instance, segmentation to automatically detect building footprints, which are essential attributes that define the urban fabric (which is critical to accelerating land cover updates with high highly accurate in terms of area and spatial assessment). The objective of this study was to implement Artificial Intelligence, especially with the Mask-RCNN method to perform building footprint detection. To enable this, aerial imagery was clipped into chip-sized images as training data for the model to learn. The model appeared to result in 73% precision. The model also shows the loss value graph, which represents the data well. Further study could focus on improving the precision of the model, which could also improve the result better.

Natural pigments are recommended to reduce the use of synthetic pigments, one of which is the primary color yellow. Carotenoids are natural yellow to red pigments that are produced naturally by plants and microorganisms. Fermentation of carotenoids by the microorganism Neurospora sitophila is one solution to the challenges of plant based pigment which compete with the needs of food, land, and dependence on weather and seasons. Corn cobs are one of the cellulotic wastes that can be used as a carbon source. This research aims to examine the effect of corn cob size (60, 20, 8 mesh) and fermentation time (3, 6, 9 days) on the carotenoid pigments produced. The spectrophotometer analysis show that fermentation increase the initial carotenoids concentration in corn cobs. The smaller the substrate and the longer fermentation time, the greater the concentration of carotenoids produced. The highest concentration was obtained on 60 mesh substrate with 9 days fermentation at 31.79 ppm. FTIR analysis shows the presence of carotenoid pigments by the C=C and C-H, and the O-H functional group which represent zeaxanthin, astaxanthin and neurosporaxanthin compounds. Based on SEM test results, the average particle size of corn cob powder was 50 μm with porosity of 67.93%.

In recent years, butterfly peas flowers (Clitoria ternatea) have gained popularity as natural colorants such as cosmetic, pharmaceutical, textile, and food colorants. Especially as the cosmetic colorant, Clitoria ternatea has been used as a nail and hair colorant. The blue color of Clitoria ternatea is primarily due to anthocyanin content. In this research, Clitoria ternatea was utilized as a natural colorant in the formulation of compact powder eyeshadow. This research aims to produce anthocyanin extract from Clitoria ternatea through extraction and vacuum evaporation processes at optimum conditions and to utilize the extract in eyeshadow formulations. Clitoria ternatea was extracted in stirrer-equipped extractor using an ethanol solvent at 50°C for 30 minutes, then concentrated with a vacuum evaporator at 65°C. The results indicated that the total anthocyanin extracted from Clitoria ternatea was 2.889 mg/g. Compact powder eyeshadow was prepared in four different formulas and contained Clitoria ternatea extract concentration of 4% (F1), 8% (F2), 12% (F3), and 16% (F4). Each formula was evaluated by conducting organoleptic, pH, spreadability, irritation, and hedonic tests. The results of F2, F3, and F4 showed stable and more intense color production. The most optimal formula is F4 due to the highest enthusiast on the hedonic test.

Background: This study describes factors promoting child labour in small-scale gold mines in rural Tanzania, a pernicious problem despite the country's adoption of laws and regulations intended to curb it. Methods: Employing a phenomenological design, we collected qualitative data using focus group discussions and in-depth interviews to describe factors promoting children's engagement in small-scale gold mining activities in three districts in Tanzania. Data analysis applied constructs from the ecological system theory. Results: Child labour was reported to be common in the small-scale gold mines and abject household poverty was reported as the main factor pushing children to work in the mines because of their respective households’ inability to provide for their basic needs. Other underlying factors stated included divorce and family disintegration and limited diversification of income-earning activities. The migratory nature of artisanal mining led some miner parents to not prioritize the education of their children. Furthermore, peer pressure and parental influence, especially of mothers, promoted entry into mining or reinforced its continuation. Early socialisation of children as future miners and lack of perspective and societal expectations of other life trajectories contributed to persistent child labour within mining communities. At the government level, the study participants mentioned poor reinforcement of mining regulations as another factor that legitimised child labour in the mines. Conclusion: Since factors promoting child labour in small-scale gold mines are multifaceted, efforts for its elimination require a multi-layered approach aimed at addressing the root-causes at the micro-, meso-, exo- and macro-level systems.

The modern retail business is currently growing rapidly along with the times. Economic progress has also contributed to the development of the modern market and retail business in Indonesia. The modern retail business has now expanded to various cities in Indonesia. Even modern shops with minimarket franchises have spread to a number of cities and districts. Modern retail business in the form of hypermart, Indomaret, Alfamart, department store and wholesaler. While shopping centers can be in the form of malls and trade centers. The focus of this research is how are modern retail business practices and how is consumer protection in modern retail businesses?. The data in this study were collected using the methods of observation, interviews and documentation. This type of research is an empirical juridical research using a socio legal approach. The results in this study are first, modern retail business which is a development of traditional retail. In practice, the business applies modern concepts by utilizing technology and accommodates lifestyle developments at the community and consumer level. However, there are still frequent price mistakes made by business actors to consumers. This starts from the unsynchronized price listed on the displayed product with the price stored in the computerized system (product data input on the computer application) at the cashier. Second, business actors need to make efforts to synchronize prices so that price errors do not occur, as well as pay attention to the total purchases that are calculated automatically by the computerized system (product data input on computer applications) and the money that consumers give. Buyers as consumers get protection under the Consumer Protection Act and khiyar aibi in Islamic law. Increasing the accuracy and accuracy of modern retail business actors must always be done, and consumers are required to be smarter in this contemporary muamalah era, by understanding a good transaction method to avoid unwanted things.

Abstract Intolerance and extremism have recently increased in the academic atmosphere or among students. The purpose of this study was to discover the origins of intolerance and radicalism among students, identify the core cause of educational problems, and examine the role of cultural education in building the character of Indonesian students. The Delphi approach was used to assess data gathered from a variety of expert informants. The study's findings revealed four significant causes of intolerance and radicalization: personal factors, education, economic-social-political-cultural issues, and a lack of religious comprehension. The study also found that religious education is less in-depth, with less reading, weak persuasive logic, and a focus on binary truth. Cultural education begins with establishing superior national identity through the Pancasila character ("gotong-royong" or cooperation, empathy, and good critical-thinking abilities); fosters the habit of reading texts critically and comprehensively. Both serve as the foundation for pupils' capacity to solve complex challenges. This study makes recommendations for promoting pupils' religious belief in God and tolerance values. Intoleransi dan ekstremisme akhir-akhir ini meningkat di lingkungan akademik atau di kalangan mahasiswa. Tujuan dari penelitian ini adalah untuk mengetahui asal mula intoleransi dan radikalisme di kalangan siswa, mengidentifikasi inti penyebab masalah pendidikan, dan mengkaji peran pendidikan budaya dalam membangun karakter siswa Indonesia. Pendekatan Delphi digunakan untuk menilai data yang dikumpulkan dari berbagai informan ahli. Temuan penelitian mengungkapkan empat penyebab signifikan intoleransi dan radikalisasi: faktor pribadi, pendidikan, masalah ekonomi-sosial-politik-budaya, dan kurangnya pemahaman agama. Studi tersebut juga menemukan bahwa pendidikan agama kurang mendalam, dengan bacaan yang kurang, logika persuasif yang lemah, dan fokus pada kebenaran biner. Pendidikan budaya diawali dengan pembentukan jati diri bangsa yang unggul melalui karakter Pancasila (“gotong-royong” atau kerjasama, empati, dan kemampuan berpikir kritis yang baik); menumbuhkan kebiasaan membaca teks secara kritis dan komprehensif. Keduanya berfungsi sebagai dasar bagi kapasitas siswa untuk memecahkan tantangan yang kompleks. Kajian ini memberikan rekomendasi untuk mempromosikan keyakinan agama siswa kepada Tuhan dan nilai-nilai toleransi. How to Cite: Cardinale, P., Rofi’I, M. S., Samputra, P. L., Achdiawan, R. (2021).

Abstract Background Household chicken production presents an opportunity to promote child nutrition, but the benefits might be offset by increased environmental contamination. Using household surveys, direct observations, and in-depth interviews with woman caregivers, we sought to describe the relationship between chicken management practices and household exposure to environmental contamination, and assess barriers to adopting improved husbandry practices. Methods First, we analyzed baseline data from 973 households raising chickens in the two interventions arms from the Agriculture-to-Nutrition (ATONU) study in Ethiopia to assess the relationship between animal management practices and environmental exposures. Second, we conducted six-hour direct observations of children’s environmental exposures in 18 households. Among these households, we analyzed in-depth interviews with child caregivers. Results Quantitative analyses showed that households raised approximately 11 chickens, had animal feces visible on the property 67% of the time, and children’s hands were visibly dirty 38% of the time. Households with more chickens had lower exposure to animal feces. Having a chicken coop increased the risk of observing animal feces on the property by 30%, but among those with a coop, having an enclosed coop reduced that risk by 83%. Coops that were enclosed, had fencing, and were located further from homes were associated with a reduced risk of observing animal feces and an increased likelihood of children having clean hands. Direct observations showed that chicken coops were often poorly designed or not used. On average, 3 to 5 chickens were inside homes at a time, and livestock and domestic animals were frequently inside of houses and interacting with young children. In-depth interviews revealed that protection of animals, maintenance of household cleanliness and health, type of chicken (local versus improved) and resource constraints influenced management decisions. Conclusions Improvements in chicken management practices could mitigate the exposure of household members to environmental contamination. Our findings highlight the need for training and resources to promote safe animal husbandry practices and optimal child health in nutrition-sensitive livestock projects. Trial registration Clinical trials number: NCT03152227 ; Retrospectively registered at ClinicalTrials.gov on May 12, 2012.

Abstract Background Despite extensive efforts to scale up counseling and testing services and care and treatment clinics (CTCs) in Tanzania, linkage between points of diagnosis and CTCs remains low. Studies have looked at barriers such as lack of trained health providers, poor referral system, economic costs or distance to health facilities, but fewer assessed the association between caregivers’ vulnerability such as disability and linkage of orphans and vulnerable children (OVCs) in their care to health facilities. This study describes the magnitude of caregivers’ disability and assesses its relationship with successful linkage to care of their OVC living with HIV/AIDS in Tanzania. Methods Data for this analysis came from the USAID Kizazi Kipya project in 79 councils of Tanzania. Data on HIV risk, service use and ART adherence among OVC aged 0–19 years were collected during the project’s quarterly routine data collection (Oct 2017-Sep 2018). Characteristics of caregivers were collected during the project beneficiary screening and enrollment process. Generalized estimating equation models were used to analyze the factors that are associated with linkage of 14,538 HIV positive OVC to CTC, who were taken care of by 11,834 caregivers. Results The majority of caregivers (70%) were females, had completed primary education (67%), 54% were married or cohabiting. Of all the OVC, 3% were living with disabled caregivers; of whom 89% were physically disabled while 11% were mentally disabled. OVCs living with disabled caregivers were less likely to be linked to care (OR 0.76, 95% CI 0.58, 0.99). Factors positively associated with OVC linkage to care were high caregivers’ education level (OR 1.99, 95% CI 1.51, 2.63) and OVC living with a HIV positive caregivers (OR 1.25, 95% CI 1.12, 1.41). OVC living in household with high socio-economic status were less likely to be linked to care (OR 0.76, 95% CI 0.67, 0.86) than those in low-SES households. Conclusion These results suggest HIV positive OVC living with disabled caregivers had poor linkage to care. The findings highlighted the need to focus attention to the disabilities-led household to promote inclusion and improve access to the HIV services.

Abstract Background HIV status disclosure facilitates receipt of HIV prevention and treatment services. Although disclosure to sexual partners, family members or friends has been extensively studied, disclosure to community-based HIV programs is missing. This study assesses the magnitude of, and factors associated with undisclosed HIV status to a community-based HIV prevention program among caregivers of orphans and vulnerable children (OVC) in Tanzania. Methods Data are from the USAID-funded Kizazi Kipya project that seeks to increase uptake of HIV, health, and social services by OVC and their caregivers in Tanzania. Data on OVC caregivers who were enrolled in the project during January–March 2017 in 18 regions of Tanzania were analyzed. Caregivers included were those who had complete information on their HIV status disclosure, household socioeconomic status, and sociodemographic characteristics. HIV status was self-reported, with undisclosed status representing all those who knew their HIV status but did not disclose it. Multilevel mixed-effects logistic regression, with caregivers’ HIV status disclosure being the outcome variable was conducted. Results The analysis was based on 59,683 OVC caregivers (mean age = 50.4 years), 71.2% of whom were female. Of these, 37.2% did not disclose their HIV status to the USAID Kizazi Kipya program at the time of enrollment. Multivariate analysis showed that the likelihood of HIV status non-disclosure was significantly higher among: male caregivers (odds ratio (OR) = 1.22, 95% confidence interval (CI) 1.16–1.28); unmarried (OR = 1.12, 95% CI 1.03–1.23); widowed (OR = 1.12, 95% CI 1.07–1.18); those without health insurance (OR = 1.36, 95% CI 1.28–1.45); age 61 + years (OR = 1.72, 95% CI 1.59–1.88); those with physical or mental disability (OR = 1.14, 95% CI 1.04–1.25); and rural residents (OR = 1.58, 95% CI 1.34–1.86). HIV status non-disclosure was less likely with higher education (p

Abstract Healthy maternal diets during pregnancy are an important protective factor for pregnancy‐related outcomes, including gestational weight gain (GWG) and birth outcomes. We prospectively examined the associations of maternal dietary diversity and diet quality, using Minimum Dietary Diversity for Women (MDD‐W) and Prime Diet Quality Score (PDQS), with GWG and birth outcomes among women enrolled in a trial in Tanzania (n = 1190). MDD‐W and PDQS were derived from a baseline food frequency questionnaire. Women were monthly followed until delivery, during which weight was measured. GWG was classified based on the 2009 Institute of Medicine guidelines. Adverse birth outcomes were classified as low birth weight (LBW), small for gestational age, large for gestational age, and preterm birth. 46.2% participants had MDD‐W ≥ 5. Mean score of PDQS was 23.3. Maternal intakes of nuts, poultry, and eggs were low, whereas intakes of sugar‐sweetened beverages and refined grains were high. MDD‐W was not associated with GWG or birth outcomes. For PDQS, compared to the lowest tertile, women in the highest tertile had lower risk of inappropriate GWG (risk ratio [RR] = 0.93, 95% confidence interval [CI]: 0.87–1.00). Women in the middle tertile group of PDQS (RR = 0.72, 95% CI: 0.51–1.00) had lower risk of preterm birth. After excluding women with prior complications, higher PDQS was associated with lower risk of LBW (middle tertile: RR = 0.55, 95% CI: 0.31–0.99, highest tertile: RR = 0.52, 95% CI: 0.29–0.94; continuous per SD: RR = 0.77, 95% CI: 0.60–0.99). Our findings support continuing efforts to improve maternal diet quality for optimal GWG and infant outcomes among Tanzanian women.

The end of the pandemic era has brought new changes and challenges to lectures held in a blended learning environment, one of which is the use of interactive content. The objective of this study was to analyse, develop and evaluate the presentation of content using H5P in blended learning, its relevance to lecture topics, activities to achieve learning outcomes using the rotation-type blended learning model and how students perceive it after using this H5P content. It focused on the rotation model that is commonly used in blended learning. However, this model has not included H5P much yet. The sampling method was purposive. The data were collected using a Likert scale questionnaire. The questionnaire data were examined using the bivariate Pearson correlation approach. The results of this study indicated that the use of H5P as a supporting component in implementing the rotation model type of integrated learning increases student knowledge, skill and satisfaction. Lecturers can apply H5Pbased content as content support in blended learning for other study programmes by following the content development steps, type rotation scenario and how the H5P interactive videos are used.

The association between hunger and adherence to antiretroviral therapy (ART) is less known especially in vulnerable populations receiving HIV care and treatment services. Caregivers of orphans and vulnerable children (OVC) are vulnerable and likely to experience hunger due to additional economic pressure in caring for OVC. Using data from the community–based, USAID–funded Kizazi Kipya project, this study assesses the association between hunger and ART adherence among caregivers of OVC in Tanzania. HIV positive caregivers enrolled in the project from January to July 2017 were analyzed. The outcome variable was adherence to ART, defined as “not having missed any ART dose in the last 30 days,” and household hunger, measured using the Household Hunger Scale (HHS), was the main independent variable. Data analysis included multivariable logistic regression. The study analyzed 11,713 HIV positive caregivers who were on ART at the time of enrollment in the USAID Kizazi Kipya project in 2017. Aged 48.2 years on average, 72.9% of the caregivers were female. While 34.6% were in households with little to no hunger, 59.4 and 6.0% were in moderate hunger and severe hunger households, respectively. Overall, 90.0% of the caregivers did not miss any ART dose in the last 30 days. ART adherence rates declined as household hunger increased (p < 0.001). Multivariable analysis showed that the odds of adhering to ART was significantly lower by 42% among caregivers in moderate hunger households than those in little to no hunger households (OR = 0.58, 95% CI 0.50–0.68). The decline increased to 47% among those in severe hunger households (OR = 0.53, 95% CI 0.41–0.69). Hunger is an independent and a significant barrier to ART adherence among caregivers LHIV in Tanzania. Improving access to adequate food as part of HIV care and treatment services is likely to improve ART adherence in this population.

There is growing evidence that home vegetable gardening interventions improve food security and nutrition outcomes at the family level. Sustainability of many of these community interventions remain a challenge. This study assessed factors influencing the sustainability of homestead vegetable production intervention in Rufiji district, Tanzania, one year after the cessation of external support. This was a community based cross-sectional study using both quantitative and qualitative data collection methods. A total of 247 randomly selected women from households who participated in the homestead vegetable intervention were interviewed using a structured questionnaire. The study held four focus group discussions with women from households that participated in the intervention, and four In-Depth interviews with two extension workers, one community health worker, and one agriculture district officer. Multiple logistic regression for quantitative data and thematic analysis for qualitative data was conducted. About 20.24% (50/247) of households sustained homestead vegetable production for one year after the intervention phased out. Shortage of seeds (adjusted odds ratio = 0.65: CI = 0.46–0.93, p-value 0.018) and either manure or fertilizers (adjusted odds ratio = 1.62: CI = 1.04–2.46, p-value 0.031) were significant factors influencing the sustainability of homesteads vegetable production. In the Focus Group discussions (FGDs) and In-Depth Interview (IDIs), all participating women and extension workers reported high cost of water, destruction from free-grazing animals, agriculture pests and diseases, poor soil fertility, shortage of seeds, and lack of capital affected homestead vegetable production sustainability. Existing individual, community, and system challenges influence the sustainability of external-funded agriculture and nutrition interventions. The study findings underscore the importance of community authorities, scientists, and policymakers in having a well-thought sustainability plan in all promising external-funded interventions.

The purposed of this study was to determine the effect of dietary energy and protein balance on the wing weight and breast weight of native chicken using meta-analysis technique. This study used meta-analysis technique to integrate 116 data from 8 articles that contain information about effect of energy and protein balance rations on wings weight and breast weight of local chicken. The meta-analysis technique begins with collecting data from several scientific publications that contain energy and protein levels. The data was tabulated in the form of database with the help of Microsoft excel and in this tabulation process the units of each data were equalized tabulated and analysed using SAS. The results of this study concluded that it took 17.04% of dietary crude protein to produce a minimum breast weight of 151.96grams and 2953.31 kcal/kg to produce 122.66grams of breast weight, as well as 17.43% of raw proteins to make a minimum wing weight of 88.25gram and 2970 kcal / kg to produce an 89.53gram of wing. In conclusion protein requirements and energy metabolism, each pile showed varying results. The existence of this diversity is influenced by genetic and environmental factors.

Abstract Background Intermittent preventive treatment during pregnancy (IPTp) is a highly-recommended intervention to prevent maternal and neonatal complications associated with malaria infection. Despite fairly high antenatal care (ANC) coverage in Tanzania, low IPTp uptake rates represent a gap in efforts to decrease complications attributed to malaria in pregnancy. The objective of this study was to examine if availability, readiness and managing authority are associated with uptake of IPTp during ANC. Methods Data for this analysis come from a cross-sectional survey, the Tanzania Service Provision Assessment conducted between 2014 and 2015. Principal component analysis was used to create scores for availability of malaria services and readiness for the provision of services. Generalized estimating equation models with logit link and the binomial distribution assessed factors that impact the uptake of IPTp by pregnant women attending ANC. Results Higher fraction of women in their third trimester than second (68% versus 49%, OR = 2.6; 95% CI (2.1–3.3)), had received at least one dose of IPTp. There was a wide variation in the availability and readiness of malaria services provision and diagnostic tools by managing authorities. Public facilities were more likely than private to offer malaria rapid diagnostic test, and more providers at public facilities than private diagnosed and/or treated malaria. Women who attended facilities where direct observation therapy was practiced were more likely to have received at least one dose of IPTp (64% versus 46% who received none; p

Abstract Homestead food production (HFP) programmes improve the availability of vegetables by providing training in growing nutrient‐dense crops. In rural Tanzania, most foods consumed are carbohydrate‐rich staples with low micronutrient concentrations. This cluster‐randomized controlled trial investigated whether women growing home gardens have higher dietary diversity, household food security or probability of consuming nutrient‐rich food groups than women in a control group. We enrolled 1,006 women of reproductive age in 10 villages in Pwani Region in eastern Tanzania, split between intervention (INT) and control (CON) groups. INT received (a) agricultural training and inputs to promote HFP and dietary diversity and (b) nutrition and public health counselling from agricultural extension workers and community health workers. CON received standard services provided by agriculture and health workers. Results were analysed using linear regression models with propensity weighting adjusting for individual‐level confounders and differential loss to follow up. Women in INT consumed 0.50 (95% CI [0.20, 0.80], p = 0.001) more food groups per day than women in CON. Women in INT were also 14 percentage points (95% CI [6, 22], p = 0.001) more likely to consume at least five food groups per day, and INT households were 6 percentage points (95% CI [−13, 0], p = 0.059) less likely to experience moderate‐to‐severe food insecurity compared with CON. This home gardening intervention had positive effects on diet quality and food security after 1 year. Future research should explore whether impact is sustained over time as well as the effects of home garden interventions on additional measures of nutritional status.

Abstract Background Delayed vaccination increases the time infants are at risk for acquiring vaccine-preventable diseases. Factors associated with incomplete vaccination are relatively well characterized in resource-limited settings; however, few studies have assessed immunization timeliness. Methods We conducted a prospective cohort study examining Diphtheria-Tetanus-Pertussis (DTP) vaccination timing among newborns enrolled in a Neonatal Vitamin A supplementation trial (NEOVITA) conducted in urban Dar es Salaam (n = 11,189) and rural Morogoro Region (n = 19,767), Tanzania. We used log-binomial models to assess the relationship of demographic, socioeconomic, healthcare access, and birth characteristics with late or incomplete DTP1 and DTP3 immunization. Results The proportion of infants with either delayed or incomplete vaccination was similar in Dar es Salaam (DTP1 11.5% and DTP3 16.0%) and Morogoro (DTP1 9.2% and DTP3 17.3%); however, the determinants of delayed or incomplete vaccination as well as their magnitude of association differed by setting. Both maternal and paternal education were more strongly associated with vaccination status in rural Morogoro region as compared to Dar es Salaam (p-values for heterogeneity

Increasing solid wood demand provides an opportunity to fast-growing wood species such as Acacia mangium as semi construction and construction materials. In general, the quality of wood is affected by growth characteristics such as radial growth rate. The study about effect of growth rate on the properties of mangium wood is limited in Indonesia. Therefore, this study aimed to determine the physical and mechanical properties of mangium wood at different growth rates. Furthermore, relationship between basic density and other properties was clarified. The nine mangium trees of 4-year-old used in this study were planted in Wonogiri Regency, Central Java. Basic density, shrinkage, T/R ratio, static bending strength (MOE and MOR), compressive strength parallel and perpendicular to grain were determined. The results were analyzed with one-way ANOVA. As a result, the physical and mechanical properties of the woods showed no significant difference in three different categories of growth rates, except for radial shrinkage. Furthermore, the basic density is positively significant correlated with radial and tangential shrinkage and also compressive strength parallel and perpendicular to grain. Based on these results, it is suggesting that basic density is a good indicator for predicting physical and mechanical properties of mangium wood.

Abstract Background Nutrition-sensitive interventions such as homestead production of diverse, nutrient-rich foods, coupled with behavior change communication, may have positive effects on the nutritional status and health of rural households engaged in agriculture, particularly among women and young children. Engagement of agriculture and health extension workers in these communities may be an effective way of delivering nutrition-sensitive interventions given the dearth of trained health care providers in many developing countries. This study aims to assess the effects of integrated homestead food production, food consumption and women’s empowerment interventions using a multi-sectoral approach on women’s and child’s health and nutrition. Methods This is a cluster-randomized community-based prospective study set in Rufiji district, a rural area in Eastern Tanzania. Ten randomly selected villages within the Rufiji Health and Demographic Surveillance Site (HDSS) in Eastern-Tanzania were paired and randomly assigned to the intervention or control arm. The Rufiji HDSS dataset was used to randomly sample households with women of reproductive age and children 6–36 months. The intervention includes provision of small agricultural inputs, garden training support, and nutrition and health counseling. This is delivered by community health workers and agriculture extension workers through home visits and farmer field schools. There are three time points for data collection: baseline, midline, and endline. Primary outcomes are women’s and children’s dietary diversity, maternal and child anemia status and growth (child stunting, child wasting, women’s BMI, and women and child hemoglobin). Discussion This integrated agriculture and nutrition intervention among rural farming households is a simple and innovative solution that may contribute to the reduction of undernutrition and disease burden among women and children in developing countries. Engaging already existing workforce in the community may facilitate sustainability of the intervention package. Trial registration ClinicalTrials.gov NCT03311698, Retrospectively registered on October 17, 2017.

Abstract Background Global evidence shows that sexually transmitted infections (STIs) prevalence and sexual risk behaviours are high among youth, and knowledge about STIs is low. In Tanzania, there is limited recent evidence regarding these issues. The aim of this study was to describe the health seeking behaviour of youth reporting STI symptoms in semi-rural Tanzania and to evaluate the association of socio-demographic characteristics, STI knowledge and sexual risk behaviour with STI symptom reporting. Methods This was a cross-sectional study involving 2251 sexually experienced youth (15–24 years), who participated in a larger baseline survey of a cohort within Ifakara town. Interview data were electronically collected by trained field workers. Logistic regression analysis was used to identify factors that influence the risk of reporting STI symptoms within the past year, using Stata 12.1. Results The prevalence of self-reported STI symptoms in the past year was 19.9%. Almost all of youth had heard of STIs and 32.7% of youth could mention at least one sign. 34.4% had sought care for their STI symptoms, the majority at private facilities. Only 20% of HIV-STI co-infected youth was aware of their HIV status. Youth with more knowledge of STI symptoms reported to have had symptoms more often (OR = 1.28; 95% CI 1.01–1.62), and those reporting having first sex at 16 or under were more likely to report STI symptoms than those who delayed to 17–19 years (OR 1.27; 95% CI 1.003–1.62). Conclusion These findings highlight the need to improve the implementation of Adolescent Friendly Health Services available in Tanzania (especially in semi-rural areas). The inclusion of private facilities and pharmacies in AFHS scale-up would potentially raise the level of STI knowledge, lower the STI prevalence and reduce HIV incidence among youth.

Background:Testicular torsion is a common cause of acute scrotum and is complicated by loss of testes. Local data on testicular torsion is limited. This study therefore aimed at determining the incidence and clinical presentation of patients with testicular torsion in our setup.Methods: This retrospective study reviewed files of 90 patients admitted to our hospital with diagnosis of testicular torsion from January 2011 to December 2015.Results: The mean age of presentation was 19± 6 years. Fifty-nine (66%) of the patients presented with right sided torsion while 5 (6 %) had bilateral torsion. Acute, intermittent and missed types of torsion were seen in 59 (66%), 19 (21%) and 12 (13%) respectively. The duration of symptoms from onset tosurgery was 17± 4 hours. The testis salvage rates for acute and intermittent torsion were 18% and 21% respectively. Conclusion: Testis salvage rates were lower in our setup compared to other studies. This could be due to delays in presentation and in diagnosis. Therefore, a high index of suspicion should always be maintained in all cases of acute scrotal pain.

BackgroundTrained community workers (CWs) successfully deliver health and social services, especially due to greater community acceptance. Orphans and vulnerable children (OVC) and their caregivers (CG) often need support from several sectors. We identified CW, program and referral characteristics that were associated with success of referrals provided to OVC and their CG in Tanzania in a cross-sectoral bi-directional referral system.MethodsData for this secondary analysis come from the first two years (2017-2018) of the USAID funded Kizazi Kipya project. Referral success was defined as feedback and service received within 90 days post-referral provision. We analyzed factors that are associated with the referral success of HIV related, education, nutrition, parenting, household economic strengthening, and child protection services among OVC and CG, using generalized estimating equations.ResultsDuring the study period, 19,502 CWs in 68 councils provided 146,996 referrals to 132,640 beneficiaries. OVC had much lower referral success for HIV related services (48.1%) than CG (81.2%). Adjusted for other covariates, CW age (26-49 versus 18-25 years, for OVC aOR = 0.83, 95%CI (0.78, 0.87) and CW gender (males versus females, for OVC aOR = 1.12, 95%CI (1.08, 1.16); CG aOR = 0.84, 95%CI (0.78, 0.90)) were associated with referral success. CWs who had worked > 1 year in the project (aOR = 1.52, 95%CI 1.46, 1.58) and those with previous work experience as CW (aOR = 1.57, 95%CI (1.42, 1.74) more successfully referred OVC. Referrals provided to OVC for all other services were more successful compared to HIV referrals, with aORs ranging from 2.99 to 7.22. Longer project duration in the district council was associated with increased referral success for OVC (aOR = 1.16 per month 95%CI 1.15,1.17), but decreased for CG (aOR = 0.96, 95%CI 0.94, 0.97). Referral success was higher for OVC and CGs with multiple (versus single) referrals provided within the past 30 days (aOR = 1.28 95%CI 1.21, 1.36) and (aOR = 1.17, 95%CI (1.06, 1.30)) respectively.ConclusionCW characteristics, referral type and project maturity had different and often contrasting associations with referral success for OVC versus for CG. These findings could help policymakers decide on the recruitment and allocation of CWs in community based multi-sectoral intervention programs to improve referral successes especially for OVC.

Islamic university students in Indonesia must improve disaster literacy by developing science-Islamic integrated disaster geography textbooks. This study aims to determine the appropriateness of science-Islamic integrated disaster geography textbooks and the effect of using them on students' learning outcomes. The Dick and Carey model was used in this development. The product was validated by experts in material, design, and the integration of Islamic science and tested on students and lecturers on a limited basis. The experiment subjects were 27 Social Science Education students from Universitas Islam Negeri Maulana Malik Ibrahim Malang. Instruments are in the form of a questionnaire to determine the appropriateness of the book and test questions to determine the effect of book products on learning outcomes. Data were analyzed descriptively and using an independent sample t-test. The results showed that science-Islamic integrated disaster geography textbooks were appropriate for use in learning with an effective category (appropriateness score = 81.08%). The use of science-Islamic integrated disaster geography textbooks affected students' learning outcomes (p=0.000) < [alpha]=0.05). Further research suggests developing digital books on other materials because the Islamic science integration curriculum has been proven to improve students' learning.

Selecting the appropriate texts as the authentic material for English teaching, particularly at the university level, matched with students' mastery level is still challenging. This study attempts to investigate the readability level of reading texts through the framework of Systemic Functional Linguistics (SFL) issued by ChatGPT, focused on whether the complexity level of the texts matches the standard level of the Common European Framework of Reference (CEFR) by proposed British Council. Through the qualitative design with content analysis, this study examines eighteen texts classified following CEFR levels issued by ChatGPT. It analyzes their lexical density, grammatical intricacy, and lexical variation to know the complexity of the texts. The analysis revealed that the complexity level of the texts issued by ChatGPT has not thoroughly followed the standard level of the texts used by the British Council on the CEFR level, indicating that several texts are inappropriate with their complexity levels. It is found that the complexity level of the texts issued by ChatGPT is determined by the length of the texts that increase from the basic level to the proficient level seen from the number of words in each text, not by their lexical density, grammatical intricacy, and lexical variation indexes. The study provides implications for the lecturer to carefully select the text used as teaching material issued by ChatGPT by relying on the lexico-grammatical analysis of the text to help students achieve the comprehension stage.

The COVID-19 pandemic has changed the world in various sectors and human activities. Limiting human activity and mobility also has an impact on transportation and traffic. This study aims to calculate the capacity and performance of roads under normal pandemic conditions before PSBB (Large-Scale Social Restrictions) in April 2020 and New Normal in July 2002, as well as predict traffic conditions if the Tsunami disaster hits the city during both periods. Tsunami Evacuation roads in Padang City were selected for analysis. The Indonesian Road Capacity Manual 1997 on urban roads is used as a reference for analyzing road performance indicators. The results showed that; road performance during the PSBB period was better than the New Normal period. The effect of volume and side traffic disturbance factors in the New Normal period makes a significant decrease in performance. Through prediction simulations, if a Tsunami occurs in the two study periods, the analyzed roads can relatively serve evacuation movements. However, the capacity needs to be increased for normal conditions.

Monosodium glutamate (MSG) is a worldwide flavor enhancer. The excessive glutamate concentration in nerve tissue induces the death of nerve cells, known as excitotoxicity. In the orofacial region, the nerve cells’ death affects pain perception such as mechanical hyperalgesia and allodynia. The aim of the present study was to examine the pain response modification and the estimated total number of trigeminal ganglion sensory neurons after sub chronic oral administration of MSG. Twenty eight male Wistar rats, aged 6-8 weeks (100-150 grams) were divided into 4 groups: Control (2 mL NaCl 0.9%); 1 mg/gWB MSG; 2 mg/gWB MSG; 4 mg/gWB MSG groups. Daily oral administration of MSG was given for 30 days. The control group received NaCl per oral for the same period. The pin prick and air puff test were performed on days 1-2, days 41-42 and days 55-56. The number of trigeminal ganglion sensory neurons were estimated by the unbiased stereology method, using the approach of numerical density and organ volume reference. The results showed that the sub chronic oral administration of MSG does not modify either the orofacial pain response or the estimated total number of trigeminal ganglion sensory neurons. .
