This research is motivated by real problems, namely that there are still many students who get low math learning outcomes because they use learning models that are not in accordance with student needs. This study aims: 1) to determine the mathematics learning outcomes in classes that apply the CMP learning model, 2) to determine the mathematics learning outcomes in classes that apply the LC5E learning model, 3) to determine the effect of the difference in mathematics learning outcomes between classes that apply the CMP learning model and classes that apply the LC5E learning model at SMA Negeri 109 Jakarta academic year 2023/2024. This research used a quantitative approach with the Quasi Experimental Design method. The sample consisted of two XI classes taken randomly, with the experimental class applying the CMP model and the control class applying the LC5E model, each totalling 40 students. The results showed that there was a different effect of math learning outcomes between the two learning models. The average math learning outcomes in the experimental class (CMP) reached 88,90, while in the control class (LC5E) the average was 82,63. Hypothesis testing using the Independent Samples T-Test test shows a Sig. value of 0.032 , which means there is a different effect between the learning outcomes of the two groups. Therefore, the CMP learning model is more effective in improving students' mathematics learning outcomes than the LC5E model, especially if the instrument used is Higher Order Thinking Skill (HOTS) questions.

The use of coal as a raw material for power plants has a good economic impact, but it also has a detrimental environmental impact, particularly due to the presence of Cr and Pb, heavy metals with bioaccumulation and biomagnification qualities. Efforts to control Pb and Cr in liquid coal waste can be achieved by bioremediation. The goal of this study is to screen indigenous bacteria, identify, and test biodegradation on the best bacteria capable of degrading Cr and Pb. Bacterial screening is done experimentally in the lab. Bacterial identification is done using morphological, biochemical, and molecular genetic methods. Using atomic absorption spectroscopy to validate Cr and Pb biodegradation research. Biodegradation experiments revealed that the efficacy of indigenous bacteria reduced Pb by 216% (0.238 ppm to 0.11 ppm) and Cr by 195% (0.34 ppm to 0.174 ppm). The findings of biochemical, morphological, and molecular genetic studies revealed that the top bacterial strains were up to 96% related. using Chromobacterium haemolyticum strain W15. Chromobacterium haemolyticum strain X, an indigenous bacteria capable of degrading Cr and Pb, was successfully isolated from liquid waste.

This study uses electrocoagulation to investigate reducing heavy metal content in wastewater from discharging spent batteries. ICP-OES analysis shows that heavy metals exceed the environmental water standard. The electrocoagulation procedure was conducted within a reactor with a 500 mL volume and a rectifier with a 5 A current capacity. Three types of electrode material combinations were used: iron (Fe) and aluminium (Al) as well as Fe-Fe, Al-Al, and Fe-Al pairs with 1 cm in the distance by parallel monopolar cells. Alternating current was used with 30, 40, and 50 A/m2 current density. The best result shown in the Fe-Al electrode pair combination system at 40 A/m2 for 30 min contact time and removal efficiencies for Co, Cd, Ni, Zn, and As is 98.76, 90.73, 99.32, 97.93, and 97.78%, respectively, while for Hg it is 31.84%, even though only Cd is above the standard limit. The heavy metal bearing was confirmed using SEM-EDS in the floc and the precipitate residue. The dissolved electrode materials and electrical energy consumed are 0.32 g and 0.109 kWh/m3, respectively. This method can be a good alternative for treating wastewater compared to direct current electrocoagulation, where the electrode and energy will be less consumed.

This study aimed to investigate the removal of tartrazine dye & tetracycline antibiotic and hydrogen (H2) production simultaneously through the hybrid electrocoagulation-photocatalytic process using g-C3N4/TiO2 nanotube arrays (TiNTAs) nanocomposite. The g-C3N4/TiNTAs was used as the photocatalyst. The melamine as the precursor of g-C3N4 was varied to obtain the optimal loading on the removal of tartrazine dye & tetracycline antibiotic and hydrogen (H2) production simultaneously. The integrated acrylic photoreactor was equipped with two 250-W mercury lamps. The nanotubular morphology of TiNTAs and nanostructure features of g-C3N4/TiNTAs were examined using FESEM/EDX and HR-TEM/SAED. The XRD patterns indicated the composition of TiNTAs, confirming the presence of anatase and rutile crystalline phases. UV-Vis DRS also showed a redshift in the composite absorbance and a reduced bandgap with g-C3N4 introduction. The results showed that when tartrazine and tetracycline were treated simultaneously, tartrazine was more dominantly degraded compared to tetracycline. In mixed pollutant system condition, the H2 production increased by 17.0% and 41.1% compared to single pollutant system of tartrazine and tetracycline, respectively. The photocatalyst used in the hybrid process was the g-C3N4/TiNTAs (3 g) which provide the optimum H2 production.

The effect of ionospheric delay on the ground-based augmentation system under normal conditions can be mitigated by determining the value of the nominal ionospheric gradient (σvig). The nominal ionospheric gradient is generally obtained from Continuously Operating Reference Stations data by using the spatial single-difference method (mixed-pair, station-pair, or satellite-pair) or the temporal single-difference method (time-step). The time-step method uses only a single receiver, but it still contains ionospheric temporal variations. We introduce a corrected time-step method using a fixed-ionospheric pierce point from the geostationary equatorial orbit satellite and test it through simulations based on the global ionospheric model. We also investigate the effect of satellite paths on the corrected time-step method in the region of the equator, which tends to be in a more north–south direction and to have less coverage for the east–west ionospheric gradient. This study also addresses the limitations of temporal variation correction coverage and recommends using only the correction from self-observations. All processes are developed under simulations because observational data are still difficult to obtain. Our findings demonstrate that the corrected time-step method yields σvig values consistent with other approaches.

As an ancient Indonesian art, Batik has been recognized by the United Educational Scientific and Cultural Organization (UNESCO). Batik is one of the original handicrafts in Indonesia. This research explores three main issues of Bakaran batik legend: community leaders’ viewpoint in Juana, Pati Regency; aspects of context and implicatures; and coherences among themes, visual elements, and images. A qualitative method was conducted in this research. It was conducted in February-April 2022 with a case study at Bakaran Juana Pati district. Data collection techniques were employed through in-depth interviews, non-participatory observation, and document analysis. Data was collected using observations and interviews with eight informants. The data was analyzed using pragmatics. The findings revealed that Bakaran batik has its uniqueness explicitly in its patterns. Numerous designs in Bakaran batik patterns are associated with the legend of Nyai Ageng Danowati, a Majapahit Kingdom’s Batik expert figure who escaped from Majapahit and then lived in Bakaran village Juana district, Pati Regency. It implicitly has legendary aspects when analyzed in terms of possible patterns. Bakaran village’s legendary patterns include the Kembang Druju, the Limaran, the Gandrung, and the Magel Ati. The legend pattern’s context is typically connected with the legend of the Batik figure, Nyai Ageng Danowati, and the implicature of the legendary pattern is related to the moment of Nyai Ageng Danowati for spending her life while she was on the escapement. The visual elements and the image of the legend motif are coherent, and the visual form of the Motif theme is relevant to Nyai Danowati’s life story.

Magnesium oxide (MgO) is an essential material for producing solid oxide fuel cells (SOFC) sealant. It can be derived from bittern waste. The common approach uses membrane electrolysis, which requires complex equipment and high energy costs. Alternatively, direct electrolysis can be taken using proper parameters to maximize the production rate. This work analyzes the process according to the input voltage, which varies between 10 and 16 Volts. The designed working voltage is suitable for direct conversion from renewable sources such as photovoltaic. The evaluation shows that the working voltage notably affects the reaction rate of the bittern solution. The working voltage of 16 Volts has the lowest power factor (2.58), while the working voltage of 10 Volts indicates the highest power factor of 3.56. It makes the reaction rate for the working voltage of 10 Volts extremely low, causing the lowest production rate of MgO with only 4.27 Grams. Oppositely, the suitable working voltage improves the production of MgO up to 75%. Microscope evaluation indicates that the produced MgO from the process has a lower agglomeration concentration after heat treatment at 700 °C, which is desirable to ensure effective fuel transfer in fuel cell apparatus.

One of the new points stipulated in Law Number 23 of 2014 Concerning Regional Government is the affirmation of regional rights to establish regional policies in carrying out government affairs that are within their jurisdiction, regional rights. In the development of this regional policy, the joint jurisdictional agreement between the central and regional governments is a fundamental thing that must be considered by regional decision-makers. Regarding the abolition of regional policies, Law Number 23 of 2014 Concerning Regional Government, regulates the cancellation of a regional policy carried out by the central government, while Law Number 30 of 2014 Concerning Government Administration, regulates the cancellation on a form of a regional policy, particularly a decision to cancel local regulations on special regions. The head is canceled by the decision-making officials, either by a higher-ranking decision-making official or by court order. The inconsistency of these two regulations, in practice across regions, can lead to legal uncertainty, especially for regional policymakers.

Minerals containing TiO2 are common in Indonesia, such as ilmenite in iron sand deposits scattered along the country's coasts. Ilmenite is an important source of titanium. One method for making TiO2 from ilmenite is by solubilizing both the Fe and Ti elements in HCl and then immediately hydrolyze the Ti. The leaching of low-grade ilmenite (ground to 0.177-0.149 mm) is studied kinetically by HCl in a stirred reactor. The research was conducted using the caustic fusion method followed by HCl leaching. The leaching reaction kinetics at the optimum conditions are analyzed using response surface methodology (RSM) with a second-order polynomial equation model and SSE with the shrinking core model (SCM). The results showed that HCl concentration and leaching time were directly proportional to the leached titanium concentration. In contrast, the leaching temperature was inversely proportional. The optimum operating conditions were obtained at a temperature of 30 °C, 9 M HCl, and 120 min of leaching time. The shrinking core model is a better representation of the kinetics than RSM with a second-order polynomial equation model. Based on SCM, the rate of the leaching reaction of titanium from low-grade ilmenite is controlled by diffusion through the ash layer.

In order to fulfill the demand for high energy and capacity, an electrode with high-voltage capability, namely LiNi0.5Mn1.5O4 (LNMO) that has an operating potential of up to 4.7 V vs Li/Li+, is currently becoming popular in Li-ion battery chemistries. This research produced LNMO by using a solid-state method with only one-step synthesis route to compare its electrochemical performance with different lithium sources, including hydroxide (LNMO-LiOH), acetate (LNMO-LiAce), and carbonate (LNMO-LiCar) precursors. TGA/DSC was first performed for all three sample precursors to ensure the optimal calcination temperature, while XRD and SEM characterized the physical properties. The electrochemical measurements, including cyclic voltammetry and charge-discharge, were conducted in the half-cell configurations of LNMO//Li-metal using a standard 1 M LiPF6 electrolyte. LNMO-LiOH samples exhibited the highest purity and the smallest particle size, with values of 93.3% and 418 nm, respectively. In contrast, samples with higher impurities, such as LNMO-LiCar, mainly in the form of LixNi1-xO (LiNiO), displayed the largest particle size. The highest working voltage possessed by LNMO-LiOH samples was 4.735 V vs Li/Li+. The results showed that LNMO samples with LiNiO impurities would affect the reaction behavior that occurs at the cathode-electrolyte interface during the release of lithium-ions, resulting in high resistance at the battery operations and decreasing the specific capacity of the LNMO during discharging. The highest value, shown by LNMO-LiOH, was up to 92.75 mAh/g. On the other side, LNMO-LiCar only possessed a specific capacity of 44.57 mAh/g, indicating a significant impact of different lithium sources in the overall performances of LNMO cathode.

The purpose of this study was to determine the high temperature erosion rate of the NiCr coating on ASME SA 210 C steel using the combustion oxy fuel thermal spray method. In Circulating Fluidized Bed (CFB) boiler, there is circulation of fly ash, silica sand and air in a high temperature environment which causes erosion. High temperature erosion can be minimized by using Ni-Cr alloy coating sing the combustion oxy fuel thermal spray method. NiCr alloy is proved a able to provider a metal alloy layer composition that can withstand temperatures of 600°C with a fly ash impact speed of 200m/s. The metal alloy compositions that have been studied are NiCr, NiCrCo, NiCrWc, NiCrWcCo, and NiCrCoMo. The results of this study indicates that metal alloys are generally atteche to the substrate and withstand at a high temperatures (600°C). The highest hardness provide by NiCrWcCo alloy which is 177.46 HV. The lowest hardness is found in the composition of the NiCrCo alloy (161.71 HV). The lowest high temperature erosion rate was found in the NiCrWcCo alloy, which was -0.00481 gram/minute. This low erosion rate because the NiCrWcCo alloy produces a good weeting effect for metal alloys and has a high hardness value.

Bioactive peptides are promising functional ingredients. Due to its high protein content, snakehead fish (Channa striata) extract (SHFE) is one of the suitable parent proteins for bioactive peptides. This study aimed to investigate the production of SHFE-based antioxidative peptides in a conventional batch and continuous system facilitated by an enzymatic membrane reactor (EMR). The effects of different proteases (Alcalase, Neutrase), substrate concentrations, and enzyme-to-substrate ratios were investigated in the batch process. Continuous hydrolysis was then performed under the optimum conditions obtained from the batch process. The optimum conditions based on the antioxidant capacity measured by DPPH and FRAP assays were employing Alcalase with a substrate concentration [S] of 3% (w/v) and an enzyme-to-substrate ratio [E]/[S] of 10% (w/w). Continuous operation was shown to have been performed over a prolonged period, based on the calculated fouling rate. Furthermore, filtration of the resulting permeate with a smaller membrane pore size (2-kDa) increased the antioxidant capacity. This study is expected to increase the production of functional ingredients in snakehead fish.

Flours made from a mixture of purple sweet potato, corn, and sago have potential use in producing analog rice. The desired analog rice should contain good nutritional value, bioactive components, and have a long shelf life. The aim of this study was to evaluate the physicochemical characteristics of analog rice made from these mixed flours and to determine its shelf life. To produce the analog rice, a mixture of 2700 g purple sweet potato flour, 2700 g corn flour, 600 g sago flour, and 120 g glycerol monostearate was used with a twin-screw extruder. The resulting analog rice was analyzed for its chemical composition, total phenolic and anthocyanin content, antioxidant capacity, and shelf life using the critical moisture content method. The analog rice was found to be high in carbohydrates as the main component (81.1%) and contained a total phenolic content of 75.0 mg/100g, anthocyanin content of 19.28 mg/100g, and antioxidant activity of 54.66%. The natural purple color of the rice analog was attributed to the presence of anthocyanin (L= 36.7, a=6.54; b=3.05). When stored in polypropylene packaging at a temperature of 30°C and relative humidity (RH) of 75%, the shelf life of the analog rice was found to be 6.0 months. Different storage conditions and packaging types resulted in varying shelf-lives.

Background and Aim: The impact of exogenous melatonin on the sperm quality of small ruminants is controversial. Therefore, this study aimed to synthesize previous findings on the influence of melatonin injection on sperm quality, steroid hormones, and testicular blood flow in small ruminants. Materials and Methods: Thirty studies were analyzed by computing the raw mean difference (RMD) as the effect size between the control and melatonin treatment groups, using the inverse of the variance for the random-effect model of the method of moments by DerSimonian and Laird. We assessed heterogeneity among studies using Q test. I2 statistic was used to classify the observed heterogeneity. We used Egger’s regression method to indicate publication bias. Results: Melatonin injection (p < 0.05) affected sperm concentration (RMD = 0.42 × 109/mL), morphology (RMD = 2.82%), viability (RMD = 2.83%), acrosome integrity (RMD = 4.26%), and DNA integrity (RMD = 1.09%). Total motility (RMD = 5.62%), progressive motility (RMD = 7.90%), acrosome integrity (RMD = 8.68%), and DNA integrity (RMD = 2.01%) of post-thawed semen in the melatonin-treated group were also increased (p < 0.05). Similarly, treatment with melatonin (p < 0.05) enhanced total motility (RMD = 5.78%), progressive motility (RMD = 5.28%), curvilinear velocity (RMD = 4.09 μm/s), straight-line velocity (RMD = 5.61 μm/s), and average path velocity (RMD = 4.94 μm/s). Testosterone (RMD = 1.02 ng/mL) and estradiol 17-ß levels (RMD = 0.84 pg/mL) were elevated (p < 0.05) in the melatonin-injected group. Melatonin implantation ameliorated testicular blood flow, as indicated by a significant reduction (p < 0.05) in the resistive index (RMD = 0.11) and pulsatility index (RMD = –0.15). Conclusion: Melatonin administration can increase the reproductive performance of small male ruminants.

Critical Thinking (Hereafter, CT) significantly correlates to the EFL students' speaking ability; students with high critical thinking perform better than students with low critical thinking. Several strategies can be implemented for initiating CT in the classroom. One of them is using language style conveyed by the teachers. However, few studies concern about this pragma-stylistic usage in the teaching-learning process. Therefore, this current study aims to analyze (1) types of pragma-stylistics strategies used by teachers in initiating the EFL university students' CT in oral mode; (2) the ways teachers use pragma-stylistics strategies in initiating the EFL university students' CT in oral mode; and (3) the teachers' perception of the students' response towards initiating the CT in oral mode. Qualitative descriptive using Interview was conducted to collect the data. The result showed that teachers prefer using Assertive-Stating, Assertive-Suggesting, Directive-Advising and Prolepsis strategies to initiate students' CT in their speaking classroom. They implement those strategies through some activities during the class, such as giving stimulus (text, audio, and video) in a particular theme, conducting group discussions or speaking club, providing instructions or questions, and giving feedback. Besides, the teachers pointed out that most students positively respond to the strategies that they have utilized. The strategies effectively motivate and encourage the students to enhance their CT. Furthermore, this study suggests language teachers initiate their students' CT through the pragma-stylistic strategies mentioned. Finally, further researchers are expected to discuss the same field in more comprehensive scopes with different language skills.

Agrarian reform is a strategic policy that aims to redistribute land to the community, tiny farmers, and tenants to reduce land ownership inequality and improve people's welfare. Land inequality in Indonesia is very high, with the land tenure Gini index reaching 0.68, higher than the income Gini index, which stands at 0.388. This inequality not only creates socio-economic problems such as poverty and agrarian conflict but also impacts national resilience. This research uses SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis to evaluate the implementation of agrarian reform policy and determine the right strategy to accelerate its implementation in supporting national resilience. This analysis identifies several strengths in the agrarian reform policy, such as government commitment and adequate infrastructure support. However, areas for improvement, such as lack of optimization of access to agrarian reform programs and slow resolution of land disputes, were also found. Opportunities include community empowerment and increased economic resources, while threats come from resistance from parties with specific interests and challenges in land redistribution. The results of this analysis are expected to provide strategic recommendations to improve the implementation of agrarian reform policies, such as strengthening cross-sectoral cooperation, increasing socialization and training, and improving access to information for the community. Thus, an effective agrarian reform program is expected to enhance community welfare and contribute to national resilience.

ARTICLE HIGLIGHTS - Nickel mining activities significantly impacted the ecological integrity of the Pomalaa coastal area in Southeast Sulawesi, particularly in the mangrove ecosystem. - The exposure of overburden waste in the mangrove ecosystem has led to the loss of important gastropod species and a decline in population of surviving species - The low population of gastropod species in nickel mining impact areas indicates extensive environmental damage caused by these activities. ABSTRACT Gastropod resources in the Dawi-Dawi mangrove ecosystem, Southeast Sulawesi are greatly influenced by the input of overburden waste (sediment) from nickel mining activities. This condition has been going on for the last 2 decades and has degraded the habitat and structure of the gastropod community. The upstream connectivity (the existing nickel mining area) and the Dawi-Dawi River estuary mean that the mangrove forest (estuary) in this area is continuously affected by (massive) overburden runoff. This research was carried out in June-August in the mangrove ecosystem of Dawi-Dawi Village, Southeast Sulawesi Province. This research aims to determine the existing condition of mangrove gastropods affected by overburden. This research began by conducting initial observations in the field, to identify mangrove ecosystems affected by overburden. research stations were determined using a purposive sampling technique (targeted) and sampling gastropods using a simple random sampling method. The ecological index of the mangrove gastropod community affected by overburden shows a tendency for a medium diversity index (H'=1.81), low species richness (R=1.42), high evenness (E=1.12), and no dominance of certain species (C=0.19). The gastropod species found are typical types that make up the mangrove fauna, namely Terebralia sulcata, Terebralia palustris, Faunus ater, Telescopium telescopium, Hebra nigra, and several taxa (genus) of climbing Littoraria snails (periwinkle) which are found in the roots, stems and leaves of mangroves. The abundance of gastropods obtained was also very low, namely around 0-12 Ind./m2. At some points (rarely) schools of small snails of the type T. sulcata (5-21 Ind./m2) are sometimes found. This research shows de facto that overburden waste eliminates (survival) or reduces the diversity and richness of gastropod species (ecological index) in the mangrove ecosystem of Dawi-Dawi.

Purpose – This study examines the factors driving and barriers to financial inclusion in Organisation of Islamic Cooperation (OIC) countries. Methodology – This study employs panel data analysis using fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) methods. The sample consists of OIC countries from 2011 to 2021. Findings – According to the FMOLS model, remittances, bank stability, and government debt are key drivers of long-term financial inclusion, while inflation, trade openness, and economic development act as barriers. Bank competition does not significantly impact financial inclusion. In the DOLS model, remittances and bank stability remain significant drivers, with inflation and economic growth acting as barriers. However, in the long term, financial inclusion is not significantly influenced by government debt or competition. Implications – This study offers insights for financial institutions and governments. Financial institutions should improve their access to low-income groups and small businesses. Governments should promote financial inclusion and stability through sound macroeconomic policy. Policymakers can use these findings to focus on key factors for a sustainable economy. Originality – This study fills a gap by exploring the factors affecting financial inclusion in OIC countries, a less-studied topic. It also uses additional indicators to measure the financial inclusion index, leading to more comprehensive results.

Maize is one of the most important food commodities after rice and is widely cultivated because it has a high protein value. The purpose of this study was to determine the effectiveness of the coating material on the growth and yield of maize under saline stress. This research was conducted in the Agroecotechnology greenhouse of the Faculty of Agriculture, University of Trunojoyo Madura from August 2022 to January 2023. This study used a factorial Completely Randomized Design (CRD) with 10 treatment combinations and 3 replications with a factor of one coating material (P) and a factor of two salinity (K). The coating material factor consisted of 5 treatments namely control (P0), bentonite (P1), biochar (P2), light coal (P3), and biochar compost (P4), the saline stress factor consisted of 2 treatments namely control (K0) and saline (K1). The results showed that the application of coating material to saline stress had a significant effect on all growth parameters. The interaction between treatments only had a significant effect on plant height at 1 MST, leaf area at 6 MST, and 100 seed weight. Treatment (P2K1) with biochar and saline showed the best results on all growth and yield parameters of maize. Saline stress reduced the percentage of growth and yield of maize by about 50%.

Non-invasive potato defects detection has been demanded for sorting and grading purpose. Researches on the classification of the defects has been available, however, investigation on the severity level calculation is limited. For the detection of the common scab, it has been found that imaging in the infrared region provide an interesting characteristic that could distinguish defected area to normal area. Thus, investigations on this wavelength range is interesting to add more knowledge and for applications. In this research, the multispectral image has been obtained and investigated especially at three wavelengths (950, 1 150, 1 600 nm). Image pre-processing and pseudo-color conversion techniques were explored to enhance the contrast between defects, normal background skin area and soil deposits. Results show that external defects, such as common scab and some mechanical damage types, appear brighter in the near infrared region, especially at 1 600 nm against the normal skin background. It has been found that pseudo-color images conversion provides more information regarding type if surface characteristics compared to grayscale single imaging. Image segmentation using pseudo-color images after multiplication operation pre-processing could be used for common scab and mechanical damage detection excluding soil deposits with a Dice Sorensen coefficient of 0.64. In addition, image segmentation using single image at 1 600 nm shown relatively better results with Dice Sorensen coefficient of 0.72 with note that thick soil deposits will also be segmented. Defect severity level evaluation had an R2 correlation of 0.84 against standard measurements of severity.

Abstract Most studies evaluating the use of distiller's dried grains with solubles (DDGS) to partially replace the use of soybean meal (SBM) in diets of shrimp Litopenaeus vannamei have been carried out under laboratory conditions, which has significant differences in terms of environmental and culture conditions with the out‐door commercial pond. This study aims to extrapolate the laboratory trials into the out‐door pond condition in order to evaluate the feasibility of incorporating DDGS at various levels (D0 (0%), D5 (5%), D10 (10%), and D 15 (15%)) to replace the use of SBM for 90‐day culture period on the growth, body composition, total hemocyte count, lysozyme activity, and organoleptic characteristics of the shrimp. Seven hundred twenty shrimp (mean initial weight 1.06 ± 0.01 g) were randomly distributed into each of 40 net pens (3 × 2 × 1 per net pen) with 10 replicates per dietary treatment. The results showed an enhancement in biomass, mean weight, and thermal growth coefficient of shrimp fed with 5 and 10% inclusion levels of DDGS. Significant reduction of FCR was also observed with the use of 5 and 10% DDGS to partially replace SBM. There were no severe changes in the total hemocyte count (THC), lysozyme activity, color, aroma, and flavor of the shrimp. However, the texture of shrimp was significantly better with the use of 10 and 15% DDGS in the diet. In summary, regarding all the factors, DDGS is a promising alternative ingredient to replace the use of SBM with 5 and 10% inclusion levels and could modulate better growth, quality, and maintain the health condition of shrimp cultured in out‐door pond conditions.

Background and Aim: Irradiated chitosan can be used as a matrix for slow-release urea (SRU) production. This study aimed to (1) determine the optimal formulation of irradiated chitosan matrix for controlling nitrogen release and (2) evaluate the characteristics of SRU in vitro fermentation based on irradiated chitosan as a feed supplement. Materials and Methods: In the first phase of the investigation, four chitosan-based SRU formulations with varying amounts of acrylamide (3 and 5 g) and gamma irradiation (5 and 10 kGy) were evaluated. Scanning electron microscopy, Fourier transform mid-infrared spectroscopy, and ammonia release characteristics were used to observe morphological, functional group, and ammonia release characteristics. In the second phase of research, the most effective SRU formulation was utilized as a supplement to ruminant rations based on rice straw, sorghum straw, and alfalfa. Gas production, rumen fermentation characteristics, and methane gas production were observed in vitro. Results: On the basis of surface image analysis, the four SRU formulas generate a similar appearance. Compared with untreated urea, the SRU3 formula reduced the percentage of ammonia emission by 12.85%–27.64% after 24 h of incubation (p = 0.05), as determined by the first phase study. SRU3 became the basis for the second testing phase. The addition of SRU3 did not affect the optimal gas production in vitro. SRU3 treatment produced less gas than Optigen® treatment (p = 0.05). With regard to rumen fermentation and digestibility, Optigen® yielded better results than SRU3 (p = 0.05). However, the treatment with SRU3 resulted in reduced methane production compared to that in the control (p = 0.05). Conclusion: Irradiated chitosan as an SRU matrix may control the release of ammonia in the rumen medium. The SRU3 formulation is the most effective. The addition of SRU to rice straw-based rations reduces methane production without affecting in vitro digestibility.

The objective of this study is to assess the level of preparedness exhibited by village governments in relation to the digital transformation of public services. The advancement of Information and Communication Technology (ICT) has brought about significant transformations in both the private and public sectors. Particularly, it has played a pivotal role in driving the modernization of public services at the regional level, with a specific focus on village governance. In Indonesia and other developing nations, the process of transformation faces various challenges. These challenges encompass: a digital divide resulting from an inadequate ICT infrastructure network, limited innovation leadership, and a lack of digital literacy within the local government apparatus. This study employs a descriptive quantitative approach to further investigate the aforementioned issues. The research involved 75 village governments in Banyumas Regency, and the collected data were analyzed using descriptive statistical methods. The findings indicated that the insufficient focus and dedication of regional and village governments towards the advancement of ICT in their respective areas, along with the limited investment in enhancing the digital proficiency of government personnel, are influential factors in determining the level of preparedness of village governments for the process of digital transformation.

Background. Both miscarriage and stillbirth occur in almost 20% of clinical pregnancies, resulting in pregnancy loss. The incidence has been associated with several risk factors and events of maternal adverse health outcomes. Purpose. This study was conducted to analyze some associated factors of pregnancy loss in Indonesia. Methods. This cross-sectional study used the 2017 Indonesia DHS data involving 18,882 female participants aged 15–49 years who had ever had a gestation. Pregnancy loss was the dependent variable, whereas the independent variables included education, employment, wealth status, advanced maternal age, grand multiparity, and cigarette smokers. Finally, the author used binary logistic regression to calculate the determinants. Results. The adjusted risk of pregnancy loss was significantly higher in respondents with lower education levels (AOR=1.25; 95% CI: 1.11-1.41) and employed (AOR=1.19; 95% CI: 1.10-1.29). The lower the wealth status of women, the higher the chance of pregnancy loss. The adjusted risk of pregnancy loss was higher in women of advanced maternal age (AOR=2.03; 95% CI: 1.37-3.02), those with grand multiparity (AOR=1.91; 95% CI: 1.74-2.09), and those who cigarette smokers (AOR=1.53; 95% CI: 1.25-1.87). Conclusion. The study concluded that six variables i.e., education, employment, wealth status, advanced maternal age, grand multiparity, and cigarette smokers are strong predictors of pregnancy loss in Indonesian women. Therefore, the government should make a policy to address the determinants of the pregnancy issue.

This research utilized response surface methodology (RSM) to explore how the yield of liquid smoke obtained from ketapang wood (Terminalia catappa) is influenced by the size of wood particles and the temperature of pyrolysis. Gas chromatography-mass spectrometry (GC-MS) was used to characterize the liquid smoke. To assess liquid smoke’s antifungal effects, a petri dish bioassay was conducted using 1.0-4.0% (v/v) concentrations against Schizophyllum commune. RSM was applied to optimize vinegar from T. catappa by varying the wood particle size and the pyrolysis temperature. The optimal yield, 24.67%, was obtained with a 3.22 mm particle size and a 425°C pyrolysis temperature. The liquid smoke produced at 400-450°C completely inhibited of S. commune growth at 2.0-4.0%. The primary components of the liquid smoke at 400°C were 2-methoxy- phenol (24.85%), creosol (8.39%), 4-ethyl-2-methoxy- phenol (7.21%), 2-5-methyl-furancarboxaldehyde (4.55%), and 4-ethyl-2-methoxy-phenol (3.74%). The primary components at 425°C were 2-methoxy-phenol (25.60%), creosol (15.15%), 5-methyl-2 furancarboxaldehyde (12.75%), and 2,6-dimethoxy-phenol (9.31%).

Background and Aim: Irradiation has become a preferred method for pork preservation in recent years. Electron-beam irradiation is notably recognized for its feasibility and safety among various irradiation methods. This meta-analysis study aims to elucidate the impact of electron-beam irradiation on oxidation parameters, color, sensory attributes, and microbiological conditions in pork. Materials and Methods: A total of 79 data from 22 articles were aggregated into an extensive database. The irradiation dose ranged from 0 to 20 kGy in this current meta-analysis. The observed parameters encompassed oxidation, color, sensory attributes, and microbiological conditions. A mixed-model approach was used to perform the meta-data analysis, in which irradiation dose was treated as fixed effects and distinct studies (articles) as random effects. Results: Electron-beam irradiation resulted in an increase in thiobarbituric acid-reactive substances levels and peroxide-oxygen value of pork (p < 0.01). Conversely, total volatile-base-nitrogen values (p < 0.05) were observed. Following irradiation, the pH value, lightness (L*), redness (a*), and yellowness (b*) remained unaffected. Pork color tended to decrease after irradiation treatment (p = 0.095 and p = 0.079, respectively) at 7 and 14 days of storage. The irradiation process resulted in an increase in the values of texture and juiciness parameters (p < 0.05). However, electron-beam irradiation resulted in decreased overall acceptability (p = 0.089). In terms of microbiological status, electron-beam irradiation led to a reduction in the populations of Salmonella (p < 0.01), Escherichia coli (p < 0.01), Listeria monocytogenes (p < 0.05), and coliforms (p < 0.05) at 7 and 14 days of storage. Conclusion: Electron-beam irradiation enhances lipid peroxidation in porcine meat. The color of the meat remained unchanged after treatment. However, with regard to sensory properties, electron-beam irradiation showed a tendency to decreased overall acceptability. Most microbiological parameters decreased following electron-beam irradiation.

This study investigates the medicinal properties of Rhodomyrtus tomentosa by extracting its bioactive compounds with n-hexane, ethyl acetate, and ethanol. Ethyl acetate extract had the highest total phenolic content, while hexane extract had the lowest. The ethanol extract had the highest total flavonoid content, with hexane extract having the lowest. Ethanol extract showed the highest antioxidant activity with an IC50 value of 28.61 ± 0.56 μg/mL. Gas Chromatography-Mass Spectrometry profiling identified major compounds like menthol and salicylic acid. Fraction 6, with rhodomyrtone content of 728 μg/mL, had the most dominant rhodomyrtone compound. Higher solvent polarity correlated with higher total phenolic content, total flavonoid content, and antioxidant activity, but lower saponin content. Based on its contents, further studies are needed to investigate its ability to reduce enteric methane, enhance immunity, and adapt to climate change, both in vitro and in vivo in ruminant livestock.
