Objectives: To predict the role of different clinical and biochemical parameters in identifying nonalcoholic fatty liver disease (NAFLD) among patients with type 2 diabetes mellitus (T2DM) in Abha city, southwestern Saudi Arabia. Methods: A stratified random sample was selected. A detailed clinical and biochemical examinations were performed. Using portable abdominal ultrasound examination, NAFLD was identified. The study used receiver operating characteristic (ROC) analysis. Results: The study covered 237 T2DM patients. NAFLD was detected among 174 patients. Area under the curve (AUC) calculations showed that the ability of age, duration of DM in years, and body mass index to predict NAFLD was poor (AUC < 0.6). Similarly, biochemical factors like HbA1c%, AST, cholesterol, triglycerides, HDL, LDL, and VLDL were poor in discriminating between those with and without NAFLD among T2DM. On the other hand, the ability of ALT to predict NAFLD among T2DM was good (AUC = 0.701, 95% CI: 0.637–0.761). The analysis identified the optimal cutoff point of ALT to be ≤22.1 nmol/L. The corresponding sensitivity was 60.7% (95% CI: 53.0–68.0) and specificity was 62.5% (95% CI: 49.5–74.3). Conclusions: Early identification of NAFLD among T2DM is important. A threshold cutoff value of 22.1 nmol/L of ALT has been identified to predict NAFLD. They should be referred for ultrasound examination for NAFLD.

South Sulawesi is one of the largest rice production centers in Indonesia. Several important diseases of rice plants, such as those caused by viruses and phytoplasmas, can be transmitted by insect vectors, especially leafhoppers and stem plant. Symptoms of diseases caused by viruses and phytoplasmas are quite diverse but visually similar and difficult to distinguish. This study aims to analyze the presence of phytoplasma associated with white-backed planthopper which are commonly found in rice plantations. The research method used is by conducting surveys and explorations of insect samples in six villages in Sidrap District. White-back planthoppers found on rice plantations showing symptoms of yellowing and stunted leaves were sampled for further analysis, including total DNA isolation of insects, standard PCR amplification for insect and Nested-PCR for phytoplasma identification, gene sequencing for both amplicons, and nucleotide analysis using BLAST method and Mega X program. The PCR with CO1 primer successfully amplified a 700 bp amplicon from insects, whereas nested-PCR using fP1/rP7 primers followed by m23SR/R16F2n amplified phytoplasma supposedly around 1800 bp and 1250 bp of 16S RNA gene, respectively. The DNA sequencing analysis results indicate that the insect samples were identified as 83% Sogatella vibix species based on homology percentage analysis using BLAST and Mega X Program. As for the phytoplasma, it leans more towards the 16SrI group or Candidatus phytoplasma asteris (Aster yellows phytoplasma) with a homology percentage of 99%.

Abstract Background Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), known as fall armyworm (FAW), is a wide-scale invasion pest that resulted in crop yield loss and certainly caused critical economic damage. Therefore, several control strategies such as the application of entomopathogen agent to control the population can be applied. The study aimed to designate and identify the candidate entomopathogens fungi (EPF) from South Sulawesi to control FAW. Results The research was conducted in several stages: field exploration, isolation, purification, bioassay, and morphological or genetical identification of selected fungi. The identification found out that: Sarocladium strictum, Talaromyces purpureogenus, and Aspergillus terreus had significant mortality percentages and incubation time in killing FAW. The highest mortality percentage was obtained in the case of the A. terreus (MLN8) isolate with an average mortality of 83.33% (2 days after incubation); A. terreus (4b) with an average mortality of 76.67% (4 days after incubation); both S. strictum (3) and T. purpureogenus (2B) required 3 and 5 days to control FAW, respectively, with 73% mortality percentage. Conclusion Ultimately, the exploration of several areas in South Sulawesi discovered potential EPF to suppress the FAW population biologically. Therefore, the identification of those EPFs contributes to FAW strategies control and the development of biopesticides.

In the last decade, the detection and attribution science that links climate change to extreme weather and climate events has emerged as a growing field of research with an increasing body of literature. This paper overviews the methods for extreme event attribution (EEA) and discusses the new insights that EEA provides for infrastructure adaptation. We found that EEA can inform stakeholders about current climate risk, support vulnerability-based and hazard-based adaptations, assist in the development of cost-effective adaptation strategies, and enhance justice and equity in the allocation of adaptation resources. As engineering practice shifts from a retrospective approach to a proactive, forward-looking risk management strategy, EEA can be used together with climate projections to enhance the comprehensiveness of decision making, including planning and preparing for unprecedented extreme events. Additionally, attribution assessment can be more useful for adaptation planning when the exposure and vulnerability of communities to past events are analyzed, and future changes in the probability of extreme events are evaluated. Given large uncertainties inherent in event attribution and climate projections, future research should examine the sensitivity of engineering design to climate model uncertainties, and adapt engineering practice, including building codes, to uncertain future conditions. While this study focuses on adaptation planning, EEA can also be a useful tool for informing and enhancing decisions related to climate mitigation.

This study was conducted to evaluate the efficiency of the fungus Aspergillus carbonarius in the synthesis of copper nanoparticles (CuNPs) from copper chloride solution, with the characterization of these nanoparticles and the demonstration of their effectiveness in inhibiting the pathogenic fungus Fusarium oxysporum causing tomato root rot disease. The results indicated that the treatment of copper chloride solution at 150 mM with A. carbonarius filtrate led to the production of CuNPs which characterized by a color change from blue to green, with the highest absorbance observed at 300 nm. X-ray diffraction (XRD) results revealed the crystalline structure with peaks at angles 28.47286, 47.43258, and 56.20644 ◦ corresponding to (111), (220), and (311) planes, respectively, matching the JCPDS card number 01-081-1841. Scanning electron microscopy images showed cubic, pyramidal, and prismatic shapes with dimensions ranging from 15 - 84.291 nm. In laboratory experiment, CuNPs inhibited the growth of the pathogenic fungus, with an inhibition zone of 1.6 cm, compared to copper chloride which recorded 0.9 cm. In the field, , the treatment of CuNPs led to an increase in the stress resistance indicators, reaching the highest values for CuNPs when combined with the fungicide Medazim in the American tomato cultivar. The concentrations of total phenols and glutathione in this treatment were 2.56 mg/g and 0.322 µg/g, respectively. The lowest concentration of proline was recorded as 4.31 µg/g in the treatment involving CuNPs against the fungal infection. CuNPs with the fungicide medazim, significantly outperformed other treatments, registering lowest disease severity at 12.22% in the American cultivar, compared to the highest disease severity was recorded in the treatment with the pathogenic fungus alone, reaching 91.16% in the Dutch cultivar. CuNPs significantly increased tomato fruit weight, both in healthy and infected plants. The American, Turkish, and Dutch tomato cultivars infected with the pathogenic fungus and treated with under + medazim showed higher productivity, reaching 6432.55, 6334.34, and 6305.73 g.plant-1, compared to the lowest productivity in the treatment of these cultivars with the pathogenic fungus, reaching 1008.34, 977.45, and 833.78 g.plant-1, respectively

Semantic segmentation of Remote Sensing (RS) images involves the classification of each pixel in a satellite image into distinct and non-overlapping regions or segments. This task is crucial in various domains, including land cover classification, autonomous driving, and scene understanding. While deep learning has shown promising results, there is limited research that specifically addresses the challenge of processing fine details in RS images while also considering the high computational demands. To tackle this issue, we propose a novel approach that combines convolutional and transformer architectures. Our design incorporates convolutional layers with a low receptive field to generate fine-grained feature maps for small objects in very high-resolution images. On the other hand, transformer blocks are utilized to capture contextual information from the input. By leveraging convolution and self-attention in this manner, we reduce the need for extensive downsampling and enable the network to work with full-resolution features, which is particularly beneficial for handling small objects. Additionally, our approach eliminates the requirement for vast datasets, which is often necessary for purely transformer-based networks. In our experimental results, we demonstrate the effectiveness of our method in generating local and contextual features using convolutional and transformer layers, respectively. Our approach achieves a mean dice score of 80.41%, outperforming other well-known techniques such as UNet, Fully-Connected Network (FCN), Pyramid Scene Parsing Network (PSP Net), and the recent Convolutional vision Transformer (CvT) model, which achieved mean dice scores of 78.57%, 74.57%, 73.45%, and 62.97% respectively, under the same training conditions and using the same training dataset.

Design of cropping method and type of variety are one of the most important factors in increasing soybean productivity and the level of pest attack and predator populations. This study aims to determine the most effective planting method and variety types in an effort to increase soybean productivity in rainfed lowland areas in South Sulawesi, Indonesia. The design used in this study was the split plot design, and the varieties (PU) used were as follows: (1) Detap-1, (2) Devon-1, and (3) Derap-1. However, the subplot (AP) was a planting method and three replicates: (1) farmer’s transplanting method (transplanting row: 20 cm × 20 cm), (2) method of transplanting double rows, and (3) method of transplanting three rows. The results showed that the highest number of branchesper plant was observed in the Legowo three planting method with the Detap-1 variety. The lowest level of leaf damage due to Spodoptera litura attack was observed in the Legowo double rows planting method with the Devon-1 variety (11.07%), and the highest level of leaf damage was observed in the jajar horn planting method (farmer’s method) with the Derap-1 variety (16.47%). The level of pod damage due to Etiella zinckenella attack was the lowest on Legowo three planting method on the Derap-1 variety (9.47%) and the highest on the Legowo double rows planting method on the Detap-1 variety (14.26%). The level of pod damage due to attack by pod-sucking pest Riptortus linearis was the lowest on Legowo three planting method on the (Derap-1) variety (8.02%) and the highest on the pod-sucking pest Riptortus linearis on the Devon-1 variety (13.43%). The length of the trichomes on soybean leaves was the highest on the Devon-1 variety (30.93%) and the lowest on Derap-1 (24.81). The highest number of trichomes on soybean leaves was on the Derap-1variety (57.67) and the lowest on the Devon-1 variety (32.20). The highest length of trichomes was on soybean pods on Detap-1 (29.11) and the lowest on Devon-1 (26.52), while the highest number of trichomes in soybean pods was on Devon-1 (222.47) and the lowest on Derap-1 (148.40).

Abstract Production and utilization of grey and blue hydrogen is responsible for emission of millions of tons of carbon dioxide (CO2) across the globe. This increased emission of CO2 has severe repercussions on the planet earth and in particular on climate change. Here in, we explored advance bimetallic (BM) CuO/Ag and trimetallic (TM) CuO/Ag/NiO based nanoporous materials supported with silica nanoparticles (SiNPs) via sol–gel route. The explored nanocatalysts were characterized by Powder X-ray diffraction (P-XRD), scanning electron microscopy (SEM), transmittance electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX), and Raman spectroscopic techniques. These advance nanocatalysts were evaluated for the green hydrogen production through electrocatalysis and photocatalysis. The catalysts exhibited an exceptional catalytic performance, the onset potential for hydrogen evolution reaction (HER) was determined to be − 0.9 V BMSiNPs-GCE and − 0.7 V (vs Ag/AgCl) for TMSiNPs-GCE, whereas η@10 for BMSiNPs-GCE and TMSiNPs-GCE is − 1.26 and − 1.00 V respectively. Significantly, the TMSiNPs composite and the BMSiNPs composite exhibited superior photochemical H2 evolution rates of 1970.72 mmol h−1 g−1 and 1513.97 mmol h−1 g−1, respectively. The TMSiNPs catalyst presents a highly promising material for HER. This study reveals a cost-effective approach to develop sustainable and resourceful electrocatalysts for HER.

Enteroviruses are RNA viruses that initiate infections through the gastrointestinal (GI) tract and are associated with enteric illness in individuals of all ages. Most serious infections of enteroviruses are in infants and young children where it is the common cause of aseptic meningitis and other systemic diseases, leading to a high mortality rate. Enteroviruses belong to the small non-enveloped family of the Picornaviridae family. The virus can spread mainly through fecal–oral and respiratory routes. In the Arabian Gulf countries, the incidence of enteroviral infections is only restricted to a few reports, and thus, knowledge of the epidemiology, characteristics, and pathogenesis of the virus in the gulf countries remains scarce. In this minireview, we sought to provide an overview of the characteristics of enterovirus and its pathogenesis, in addition to gathering the reports of enterovirus infection prevalence in Gulf Cooperation Council (GCC) countries. We also present a summary of the common methods used in its detection.

The innate immune system, particularly the interferon (IFN) system, constitutes the initial line of defense against viral infections. IFN signaling induces the expression of interferon-stimulated genes (ISGs), and their products frequently restrict viral infection. Retroviruses like the human immunodeficiency viruses and the human T-lymphotropic viruses cause severe human diseases and are targeted by ISG-encoded proteins. Here, we discuss ISGs that inhibit the translation of retroviral mRNAs and thereby retrovirus propagation. The Schlafen proteins degrade cellular tRNAs and rRNAs needed for translation. Zinc Finger Antiviral Protein and RNA-activated protein kinase inhibit translation initiation factors, and Shiftless suppresses translation recoding essential for the expression of retroviral enzymes. We outline common mechanisms that underlie the antiviral activity of multifunctional ISGs and discuss potential antiretroviral therapeutic approaches based on the mode of action of these ISGs.

The samples for drinking water were collected from primary schools of ten representative districts of Sindh. This study was a part of the WASH Project funded by USAID (USPCASW Seed Grant P-II) Material & Methods: We selected 425 samples of drinking water from primary schools based on pre-defined selection criteria. We used a Quantitative Microbial Risk Analysis using indicator organisms, i.e., E. coli, to predict the possible health risks of rotavirus. Data was entered and analyzed on SPSS version 26. The graphs were developed using Arc GIS version 3. Morbidity and mortality were predicted using the Quantitative Microbial Risk Assessment (QAMRA) model. Results: Our data revealed that the highest daily risk of HRV-associated diarrhea amongst school children was 11 per 10,000 schoolchildren, resulting in 8.4% annual risk, and the minimum risk was estimated to be 1 in 10,000 children. The burden of diseases for rotavirus using the QAMRA model revealed the severity of the diarrhea. Majority of the children presented with mild diarrhea (86%) followed by severe, and the probability of death was less than

Chromium (Cr) is classified as an ecological toxin, and irrigation of soil with raw industrial effluents causes its concentration in soil and plants to reach fatal levels. Due to reduced metal mobility caused by organic amendment and availability of food for microbial activity, use of Cr-tolerant rhizobacteria in conjunction with compost has proven to be useful in supporting growth and survival of plants. We checked the simultaneous effects of rhizobacteria and compost on spinach (Spinacia oleracea) growth, physiology, biochemistry as well as uptake of Cr. Plants were treated with compost (1 % w/w) and subsequently inoculated with two different PGPR strains under Cr contamination. Among tested inoculants , inoculation of 'JS2′ strain along with compost significantly ameliorated the adverse effects of Cr on spinach, and improved root and shoot lengths (84 and 197 %), as well as their dry (104 and 89 %) and fresh (89 and 167 %) weights , along with chlorophyll content (84 %) as compared to relative control. In addition, combined application led to a significant increase in antioxidant activities, such as SOD (128 %), CAT (40 %), POD (73 %) and APX (57 %) concomitant with decreased MDA contents (68 %). Data regarding Cr movement from soil to roots and aboveground plant parts, as well as the results of translocation and bioconcentration factors, revealed that combined application of PGPR and compost reduced Cr entry to aboveground plant parts and led to its phytostabilization. Hence, compost and Cr-tolerant PGPR can efficiently immobilize Cr in soil, and reduce its harmful effects on spinach growth, physiology and other important attributes.

The interferon-induced host cell protein Shiftless (SFL) inhibits −1 programmed ribosomal frameshifting (−1PRF) required for the expression of HIV-1 Gal-Pol and the formation of infectious HIV-1 particles. However, the specific regions in SFL required for antiviral activity and the mechanism by which SFL inhibits −1PRF remain unclear. Employing alanine scanning mutagenesis, we found that basic amino acids in the predicted zinc ribbon motif of SFL are essential for the suppression of Gag-Pol expression but dispensable for anti-HIV-1 activity. We have shown that SFL inhibits the expression of the murine leukemia virus (MLV) Gag-Pol polyprotein and the formation of infectious MLV particles, although Gag-Pol expression of MLV is independent of −1PRF but requires readthrough of a stop codon. These findings indicate that SFL might inhibit HIV-1 infection by more than one mechanism and that SFL might target programmed translational readthrough as well as −1PRF signals, both of which are regulated by mRNA secondary structure elements.

- Abstract
This study was designed to investigate the associations among motives and physical activity behaviors and health in urban college students in China. Eight hundred and eighty-seven college students (521 females; M[subscript age] = 20.51, SD = ± 1.67) were recruited from four universities in South and South-central China. Participants' motives (i.e., interest/enjoyment, competence, appearance, fitness, social) toward to physical activity behaviors were measured by the established Motives for Physical Activities Measure (Ryan et al., 1997), while physical activity behaviors were assessed via the validated International Physical Activity Questionnaires for Chinese (Macfarlane et al., 2007). The data were collected in June 2016 and 2017. Participants' total metabolic equivalent (METs) was calculated as the outcome of physical activity behaviors. On average, participants reported 412 METs (SD = 290.82) of physical activity for the prior week. Correlation analysis suggested that all motive components were moderately or highly correlated with one another (r = 0.37 -0.74; p < 0.01), and these variables were significantly, yet modestly, related to physical activity behaviors (r = 0.12 -0.24; p < 0.05). Regression analyses further indicated that the whole model explained 24.5% of the variance [F (5, 394) = 5.02, p < 0.01] when using motives to predict physical activity behaviors. Interestingly, participants' interest/enjoyment was the only significant and positive predictor for their physical activity (ß= 0.23, p < 0.01). Findings suggest that Chinese college students were relatively physically active on a weekly basis. Students' interest/enjoy toward physical activity is a very important motive in promoting physical activity behavior among this population. Health professionals and educators are encouraged to offer a variety of interesting and enjoyable activities for Chinese college students with the goal of helping this population develop and maintain a physically active lifestyle.

Abstract Background COVID-19 preventive measures required a drastic shift to online teaching-learning in most of countries. Institutions used different combinations of live online lectures (synchronous) requiring students to attend the class in real-time, as well as recorded lectures uploaded by the instructors to be accessed by students as per their own convenience (asynchronous). We undertook this study to assess and compare the perceptions of students regarding their learning experiences in the synchronous versus asynchronous mode of instruction using their teaching-learning during the compulsory online mode of instruction at the peak of the COVID-19 pandemic. Methodology This cross-sectional questionnaire-based study received responses from 122 final-year medical students studying at the College of Medicine, King Khalid University, Abha, Saudi Arabia. An online 5-point Likert scale-based questionnaire was used to collect data regarding experience and perception towards synchronous and asynchronous learning. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. A P-value less than 0.05 was considered significant. Result All the students found both synchronous and asynchronous learning to be equally satisfying, enjoyable and comfortable. No statistically significant difference was found when both the methods were analyzed for enhancement of knowledge. The students opined that asynchronous learning helped them manage their time better whereas synchronous learning encouraged more interaction during the live lectures. Conclusion Overall, the students' perceptions regarding both synchronous and asynchronous online learning were positive. As both methods have their advantages/limitations, a mix of both synchronous and asynchronous methods may be adopted depending upon the content of the topic and the desired learning outcomes.

Abstract Herein, we reported the synthesis of nineteen novel 1,2,4-triazole derivatives including 1,3-diphenyl-2-(1H-1,2,4-triazol-1-yl) propan-1-ones (7a-e), 1-(1,3-diphenylpropan-2-yl)-1H-1,2,4-triazole (8a-c) and 1,4-diphenyl-2-(1H-1,2,4-triazol-1-yl) butane-1,4-diones (10a-k). The structures of these derivatives were confirmed by spectroscopic techniques like IR, 1H-NMR, Mass spectroscopy and Elemental analysis. The cytotoxic activities of the synthesized compounds were evaluated against three human cancer cell lines including MCF-7, Hela and A549 using MTT assay. Compounds 7d, 7e, 10a and 10d showed a promising cytotoxic activity lower than 12 μM against Hela cell line. The safety of these compounds was also, evaluated on MRC-5 as a normal cell line and relieved that most of the synthesized compounds have proper selectivity against normal and cytotoxic cancerous cell lines. Finally, molecular docking studies were also, done to understand the mechanism and binding modes of these derivatives in the binding pocket of aromatase enzyme as a possible target.

- Abstract
Guided by the Transtheoretical Model (Prochaska & DiClemente, 1982), this study investigated the differences of physical activity levels and correlates (i.e., self-efficacy, decisional balance, process of change) across different stages of change levels among Chinese college students. The relationships between students' physical activity correlates and physical activity behavior was also examined. The participants were 887 college students (365 males; M[subscript age] = 20.51, SD = ± 1.67) recruited from four universities in south and south-canter China. Participants completed a battery of established questionnaires assessing their physical activity correlates (self-efficacy, decisional balance, process of change) and 1-week physical activity levels. Results suggested that Chinese college students in the high stage of change group reported significantly higher physical activity levels and correlates than those in the low stage of change group. Pearson correlation analyses suggested that students' self-efficacy was moderately related to other correlates and physical activity behavior. Yet, decisional balance and process of change were only modestly associated with physical activity levels for both groups. Regression analyses further revealed students' self-efficacy emerged as the only significant contributor of their daily PA levels across the two groups. However, decision balance and process of change failed to predict physical activity levels. The implications for practice and direction of future research were discussed.

Weeds are one of the major limiting factors for wheat production. So, a study was conducted to integrate allelopathic bacteria with reduced dose of chemical herbicide for sustainable wheat production in wild oat infestation. Cyanide-producing Pseudomonas strains were applied in four combinations with and without two chemical herbicides (Axial and Atlantis) at 25% and 50% recommended dose under axenic conditions. Results showed that C4 combination significantly reduced growth and development of wild oat under 50% Axial while increase wheat growth. Afterward, C4 combination and Axial herbicide were selected for field evaluation, where it reduced the weed density (82.1%), SPAD value (26.0%) and grain yield (88.2%) under 75% Axial, and relative wild oat density (70.9%), photosynthetic rate (26.6%) and transpiration rate (25.6%) under 50% Axial in wild oat. While C4 combination improved SPAD value (26.9%), shoot length (10.1%), tillering (33.3%), biological yield (32.7%), straw yield (24.4%), grain yield (46.8%), transpiration rate (9.6%) and stomatal conductance (14.7%) in wheat under 75% Axial. The increase in growth and yield of wheat was found at par with C4 under 50% and 75% Axial. Thus, it is concluded that allelopathic bacteria could be used with 50% Axial for sustainable wheat production under wild oat.

Abstract Broccoli is one of important cole crop grown all over the world due to its unique nutritional profile consumed fresh as well as processed. It contains a wide range of nutrients, vitamins, minerals and specific anti-cancer compounds such as glucosinolates. Broccoli cultivation in Pakistan is increasing rapidly, however, till now there is no standardized cropping technology for broccoli cultivation under local climate. Considering research gap (lack of suitable varieties, poor growth, and unavailability of optimized crop technology), trial was conducted at Vegetable research area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad to evaluate the impact of bio-stimulants on different broccoli cultivars under local climatic conditions. The set of experimental treatments was laid out in Randomized Complete Block Design (RCBD) with three replications. Pre-harvest application of Isabion and Seaweed extract significantly enhanced the plant height (11%), dry weight (4%), leaf area (7%), and yield plant-1 (5%). Moreover, Isabion and seaweed extract application led to the increase in antioxidant enzymes i.e., superoxide dismutase (18%), peroxidase (38%) and catalase (12%). In crux, the foliar application of bio-stimulants (Isabion and seaweed extract) on broccoli enhanced the growth, yield, and contents of antioxidant enzymes.

It is known that normal distribution plays an important role in analysing symmetric data. However, this symmetric assumption may not hold in many real word and in such cases, asymmetric distribution, including skew normal distribution, are known as the best alternative. Constructing asymmetric distributions is carried out using the conditional/selection approach of several independent variable conditioning on other set of variables and this approach does not work well when the independence between variables violated. In this work we construct an asymmetric distribution when variables are dependent using a copula. Specifically, we consider the random vectors X and Y are connected using a copula function CX,Y and we study the selection distribution Z = (X|Y ∈ T ). We present some special cases of our proposed distribution, among them, multivariate skew-normal distribution. Some properties such as moments and moment generating function are investigated. Also, numerical analysis including simulation study as well as a real data set analysis are presented for illustration.

Dependence on imports of animal feed makes the price of animal feed expensive. On the other hand, feed costs are known to account for 70%-80% of the total production costs. This condition causes the production efficiency to be low. Utilization of alternative protein sources whose availability is abundant and does not compete with human food needs, is one of the promising solutions to optimize production efficiency. Various types of insects have the potential to be used to produce useful biomass, but the ones that have begin to be studied are the larvae of the Black Soldier Fly (BSF) or Hermetia illucens, the maggot/larvae of the house fly (Musca domestica) and the hongkong caterpillar. KKN (Community Service Program) members analyzed “Mrisi” for the cultivation of BSF larvae from looking for seeds, making a place for BSF larvae, mini experiments and distributing the harvest to the community. The BSF larvae cultivation program in Mrisi is proceeding as planned. TPS Tirto Asri has great potential in the process of cultivating BSF larvae. Good initial planning will result in good production too.
