The agricultural sector plays a vital role in supporting Indonesia's economy, particularly in food provision and increasing rural household income. One of the promising horticultural commodities is California papaya (Carica papaya L.), known for its high productivity and short harvesting cycle. This crop is favored by farmers due to its stable market demand. However, to ensure the financial feasibility of this farming enterprise, a comprehensive financial analysis is necessary. This study aims to analyze the revenue, production costs, income, and financial feasibility of California papaya farming in Hinai Subdistrict, Langkat Regency. The research employed a descriptive quantitative method through a survey approach, with a purposive sample of 34 farmers. Data were analyzed using a farm income analysis approach, including the calculation of fixed costs, variable costs, total revenue, net income, and the Revenue/Cost (R/C) ratio. The results showed that the total production cost was IDR 590.734.000, while the total revenue reached IDR 1.970.685.000. The net income obtained by farmers amounted to IDR 1.379.951.000, with an average income of IDR 40.586.794 per farmer. The R/C ratio was calculated at 3.33, meaning that every IDR 1 spent on production costs generated IDR 3.33  in revenue. California papaya farming in Hinai Subdistrict is financially feasible, provides significant profit, and has strong potential to be further developed as a primary income source for horticultural farmers.

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. The high risk of dengue transmission is greatly influenced by the density of mosquito larvae which correlates with environmental conditions and community behavior. This study aims to describe the density level of Aedes aegypti mosquito larvae in the working area of the Gandus Health Center in Palembang City in 2025 through the measurement of House Index (HI), Container Index (CI), Breteau Index (BI), Larvae-Free Numbers (ABJ), and Density Figure (DF). The method used was descriptive observational with a purposive proportional random sampling technique on 100 households in three RTs. Data was collected through direct observation using checklist sheets. The results showed that the HI was 66%, CI was 44%, BI was 107%, and ABJ was only 34%, which indicates that the larval density is very high and far below the WHO standard (≥ 95%). The DF value is in the range of 7–9, reinforcing the finding of high vector density. This condition shows that the area is at high risk of dengue transmission. Interventions are needed in the form of regular mosquito nest eradication (PSN), increasing public education, and strengthening the role of jumantic cadres in sustainable vector control.

Black Soldier Fly (BSF) larvae, or maggots, are a type of insect currently widely cultivated, primarily for animal feed. This is because BSF larvae contain essential nutrients such as fat and protein in high amounts, thus improving the nutritional quality of livestock that consume them. Therefore, the processing and preservation of maggots is crucial to maintain their nutritional content and extend their shelf life. One method used in maggot processing is drying. Drying aims to reduce the water content in the larvae, thereby preventing the growth of microorganisms that cause spoilage. One widely applied technique is drying using a microwave oven. However, before the actual process is carried out, simulations are often required to determine the distribution of heat and humidity. Simulation is one of the most effective ways to predict the drying performance of biological materials. This study used a simulation using the Computational Fluid Dynamics (CFD) method operated by Comsol Multiphysics 6.2 software. The parameters used in the simulation were an initial maggot temperature of 80°C, a drying time of 15 minutes, and a heat source of 1300 W/m³. Based on the simulation results, the final water content of the maggots was below 10%. Furthermore, the final relative humidity of the maggots ranged from 10–35%, while the final temperature of the larvae increased to 93–97°C. These results indicate that microwave drying can effectively reduce moisture content while maintaining the nutritional quality of BSF larvae. These simulation results can be used as a basis for practical maggot drying processes, thus supporting the production of efficient and nutritious animal feed.

Cassava (Manihot esculenta) is a staple food rich in carbohydrates and widely consumed by people in various regions, especially in tropical regions such as Indonesia. Besides being easy to cultivate, cassava also has a high economic value. However, cassava has a major weakness, namely its perishability after harvest. This damage is often caused by contamination by microorganisms, especially fungi, which can grow rapidly in unhygienic and humid storage conditions. Fungal contamination not only causes odor and reduces sound quality but also has the potential to produce mycotoxins that are harmful to human health. Therefore, identifying the type of fungus growing on cassava is very important. The purpose of this study was to determine the presence and type of fungus growing on cassava through a colony morphology approach and Gram staining using crystal violet. The research method began with dilution of cassava samples, then inoculated into Nutrient Agar (NA) media, incubated for 48 hours at room temperature, and continued with microscopic examination. Staining with crystal violet aims to clarify the morphological structure of the fungus such as hyphae and spores. Observations revealed the growth of characteristic fungal colonies, as well as hyphal and spore structures that readily absorbed crystal violet. This demonstrates that this simple morphological and staining method is quite effective in providing initial insights into fungal identification. This information is expected to form the basis for developing safer and more durable cassava storage methods. Further research is recommended on specific identification using molecular testing. This step will broaden our understanding of the toxicological potential and post-harvest handling of cassava.

During storage and before consumption, grains often experience a decline in quality, nutritional content, and cleanliness due to pest attacks. Botanical insecticides are considered an alternative method to reduce dependence on harmful chemical pesticides. This study aimed to evaluate the effectiveness of three concentrations of silver nanoparticles (AgNPs) synthesized from the leaves of Cymbopogon citratus against Cadra cautella (Walk.) (Lepidoptera: Pyralidae) and their potential as biological control agents. The selection of C. cautella as the test organism was based on the limited number of studies examining this pest. The AgNPs used were synthesized through an eco-friendly method, and their optical and physical properties were analyzed using UV-Vis spectroscopy. The results demonstrated that AgNPs synthesized from C. citratus extract showed high effectiveness in controlling the eggs and second instar larvae of C. cautella. Egg mortality reached 80.3% at a concentration of 40 μg/ml after 24 hours of exposure, followed by 72.9% at 30 μg/ml, and 65.8% at 20 μg/ml. In contrast, the control group showed no egg mortality. Similarly, larval mortality rates were 74.9%, 65.8%, and 60.2% for concentrations of 40 μg/ml, 30 μg/ml, and 20 μg/ml, respectively. These findings indicate that higher concentrations of AgNPs lead to greater mortality in both eggs and larvae. This study highlights the potential of green-synthesized AgNPs from C. citratus leaves as an effective and eco-friendly biopesticide. Their significant impact on egg and larval mortality suggests that they can be developed as an alternative pest control strategy in stored grains, thereby reducing reliance on conventional chemical pesticides that are detrimental to human health and the environment. Further research is recommended to explore their long-term efficacy, safety, and integration into sustainable grain storage management.

Worm infestation due to Soil-Transmitted Helminths (STH) infection remains a public health problem, especially among elementary school children who frequently interact with contaminated soil. This condition is a major concern because it can cause long-term health problems, particularly in terms of physical growth and development of children. This study aims to identify the presence of STH worm eggs and larvae in soil and fecal samples of children in Bekoso Village, Pasir Belengkong District, Paser Regency, East Kalimantan. This study used a descriptive approach with a cross-sectional design. The samples used consisted of 23 soil points taken from oil palm plantations with sandy and loose soil criteria, as well as 16 fecal samples from elementary school children. Fecal examination was carried out using the Kato-Katz method to detect worm eggs, while the soil was examined using the Baermann technique to detect worm larvae. The results showed that 25% of children's fecal samples were infected with worm eggs, with 12.5% containing hookworm eggs, 12.5% Taenia sp. eggs, and 6.25% Ascaris lumbricoides eggs. In soil samples, 60.87% tested positive for Strongyloides stercoralis larvae and 26.09% tested positive for Ascaris lumbricoides eggs. These findings indicate a high risk of STH infection in children in the area. Environmental factors such as soil moisture, soil texture suitable for worm breeding, and poor personal hygiene practices are suspected to be the main causes of the spread of infection. This study emphasizes the importance of education on clean and healthy living behaviors (PHBS) and improving environmental sanitation to reduce cases of worm infection, especially in endemic areas such as Bekoso Village. More comprehensive prevention efforts are urgently needed to address this problem and improve public health, especially among elementary school children.

Futsal is a high-intensity team sport that requires a combination of speed, agility, and physical endurance, particularly cardiorespiratory endurance. Cardiorespiratory endurance is crucial because it directly relates to a player's ability to maintain optimal performance throughout a match, particularly when facing fast-paced and stressful play. Therefore, variables that can influence this ability, such as body composition and nutritional status, are crucial in developing athlete performance. One indicator that can be used to measure nutritional status and body composition is the Body Mass Index (BMI), which is obtained by measuring weight and height. BMI not only reflects whether a person is within the ideal weight range but also potentially influences the efficiency of the body's organs, including the cardiovascular and respiratory systems. In the context of futsal, players with a higher BMI tend to have a higher body weight, which can hinder movement efficiency and increase fatigue during matches. Conversely, players with a lower BMI may have insufficient energy reserves and muscle mass to maintain stamina during matches. This study shows a significant negative relationship between BMI and cardiorespiratory endurance in futsal players at Bali International University. The results of statistical tests using the Spearman rank correlation method showed a correlation coefficient (r) of -0.504 with a significance value of p = 0.005. This indicates that the higher a player's BMI, the lower their cardiorespiratory endurance tends to be. These findings support the importance of ideal body weight management in futsal athlete training, both through dietary adjustments and measured physical exercise programs.

Pogalan Village in Pakis District, Central Java, is known as a horticultural agricultural center, with abundant vegetable production every year. However, behind this potential, this village faces a serious problem in the form of large amounts of organic waste generated from harvest residue and agricultural processing. Waste that is not managed properly has the potential to cause environmental pollution, reduce the village's aesthetics, and become a source of disease spread. To address these problems, the Tidar University Community Service Program (KKN-50) Team conducted a socialization activity for Black Soldier Fly (BSF) maggot cultivation as an environmentally friendly and economically valuable organic waste management solution. BSF maggots have been proven to decompose organic waste by up to 60% in a short time and produce useful by-products, such as dried maggots as high-protein animal feed and kasgot (used maggots) that can be used as organic fertilizer. The activity was held on July 31, 2025, at the Pogalan Village Hall, with the main participants being PKK mothers as agents of change at the household and community levels. The implementation method included initial observation of the village's potential and problems, creation of a maggot cultivation prototype, theoretical material outreach, and live demonstrations of the cultivation process. The material provided covered the BSF life cycle, cultivation techniques, selection of growing media, maggot population management, and utilization of cultivation products. The results of the activity showed high enthusiasm from participants, as reflected in the many questions and discussions during the training session, as well as their increased understanding of the benefits and techniques of maggot cultivation.

The role of Mataf (Mamar Guardians) Manufua in Sillu Village, Fatuleu District is a problem that impacts various aspects including customs and governance, legal certainty, and social stability of the local community, as well as mamar ownership. In this context, the role of mataf is very important to ensure comfort for mamar owners. This study was conducted based on the consideration that the role of mataf in Sillu Village has almost disappeared, causing misuse in utilizing natural resources from mamar that are not by their owners. In addition, this study was conducted to build the potential of human resources in Sillu Village in understanding the importance of the role of mataf in maintaining mamar. Based on the description above, the role of mataf in maintaining mamar needs to be studied using empirical legal research. The main problem in this study is how the role of mataf guards mamar Manufua in Sillu Village, Fatuleu District. Data collection techniques used were observation, interviews and literature studies. The results of the study indicate that the role of mataf in maintaining mamar in Sillu Village, Fatuleu District is quite good with the presence of guarding from mataf. Mataf are able to provide information on various events occurring within the mamar area, from harvesting mamar crops, irrigation of mamar fields, security, and collecting scattered mamar crops in one location so that mamar owners can easily identify them when collecting their Manufua mamar crops. The results of this study indicate a positive role or positive outcomes of the mataf's role in safeguarding mamar. Therefore, it is recommended that students, especially university students, or scientists, further study the potential role of mataf in a broader context.  

Andaliman fruit (Zanthoxylum acanthopodium) is a typical spice from North Sumatra with a unique, spicy flavor and is widely used in traditional Batak cuisine. Although this fruit is known for its natural antimicrobial compounds, which have the potential to prevent the growth of pathogenic microorganisms, andaliman fruit is still at risk of contamination by various microorganisms during post-harvest handling and unhygienic storage. This study aims to assess the potential presence of microbes in andaliman fruit, as well as review methods for isolating and identifying existing microorganisms. Based on a literature review, several microorganisms frequently found in fruits include bacteria from the genera Bacillus, Pseudomonas, and Escherichia, as well as molds from the genera Aspergillus and Penicillium. In the process of microbial isolation, multilevel dilution techniques and cultivation on spectrum media are common methods used. Meanwhile, microbial identification can be carried out through morphological techniques by observing the shape and color of colonies, biochemical tests to examine the characteristics of microbial metabolism, and molecular techniques such as PCR to detect specific microbial DNA. A microbiological understanding of andaliman fruit is crucial to ensure food safety, especially in traditional culinary processing that uses this fruit as a spice. Therefore, efforts are needed to raise awareness of the importance of proper post-harvest handling and storage to minimize the potential for microbial contamination and ensure the quality and safety of andaliman fruit used in cooking. Furthermore, it is crucial to develop effective processing methods to reduce the risk of microbial contamination in andaliman fruit, such as washing or heating before use in cooking. The use of modern processing technologies, such as natural preservatives or processing techniques that can maintain its quality and safety, is also crucial.

The central building of the cyber world in the city center plays a significant role in enhancing community activities, providing social space, and contributing to the city's image. As the first shopping center in Palembang City, International Plaza has historical and strategic value in the city's development. However, over time, the attractiveness of International Plaza has decreased significantly. This decline is caused by several factors, such as the development of new, more modern shopping centers and the lack of updates to the building's design elements that can attract visitors. This study aims to analyze the potential for redesigning International Plaza with a local cultural approach. In this redesign concept, the Sarinah Building in Jakarta is used as a comparative study because it has successfully combined modern concepts with the development of traditional elements that reflect local culture. The Sarinah Building, although designed with a modern approach, still maintains cultural values relevant to the surrounding community, thus creating a space that is not only functional but also has visual and emotional appeal for its visitors. The results of the study indicate that with a modern architectural approach that remains based on local culture, International Plaza has the potential to revitalize and attract visitors. The suggested redesign includes changes to the building's facade by adding ornaments typical of Palembang City, such as traditional carvings or motifs that reflect the richness of local culture. These ornaments can be applied using secondary skin techniques to building facades, which not only enhance aesthetics but also serve as sunscreens. Furthermore, zoning and tenant order are crucial for a more organized and comfortable visitor flow. Finally, enhancing the public space at the front of the building with additional public facilities, gardens, and gathering areas can create a more vibrant and enjoyable atmosphere for visitors.

Dengue Hemorrhagic Fever (DHF) remains a significant public health challenge in Indonesia, with the increasing prevalence of cases every year. One of the key methods of controlling the spread of DHF is to target the vector, Aedes aegypti mosquitoes, by eradicating their larvae. However, the widespread and continuous use of chemical larvicides has raised concerns regarding the development of mosquito resistance and environmental pollution. This community service activity aimed to provide students at Duta Karya Vocational High School with knowledge and practical skills to use natural, eco-friendly alternatives for controlling mosquito larvae, focusing on papaya seeds (Carica papaya) and alum as natural larvicides. The methods for this activity included interactive counseling, a demonstration on how to produce larvicides using papaya seeds and alum, and an engaging question-and-answer session. Thirty 12th-grade students from the Pharmacy class participated in this activity. The results revealed that the activity was highly effective in increasing the students' understanding and practical ability to independently create and apply natural larvicides. The students expressed a high level of enthusiasm and interest in the topic, actively participating in the discussions and demonstrations. As a result of this community service, the school has expressed interest in incorporating this activity into its School Health Unit (UKS) work program, which will further promote the use of natural, sustainable methods for controlling mosquito populations. The students, now equipped with the necessary skills, are ready to become "jumantik" cadres—community health volunteers responsible for monitoring and preventing mosquito larvae development. This initiative also raised awareness about utilizing organic waste, such as papaya seeds, to create valuable products for the prevention of DHF.

This study aimed to evaluate the effect of post-larvae (PL) 12 density of whiteleg shrimp (Litopenaeus vannamei) on survival during transportation using a closed wet system. The study was conducted experimentally using four different density treatments: 500, 750, 1000, and 1250 shrimp per liter of water. The purpose of these density variations was to identify the optimal density level that still ensured a high survival rate during transportation. The results showed that shrimp seed density significantly influenced survival. A density of 500 shrimp/liter resulted in the highest survival rate of 99.6%, while a density of 1250 shrimp/liter showed the lowest survival rate of 99.30%. Although the differences in numbers appear small, the ANOVA statistical test showed that the differences between the treatments were significant. These results were reinforced by a further LSD (Least Significant Difference) test, which confirmed significant differences between treatment groups. In addition, water quality parameters such as dissolved oxygen, temperature, and pH were also observed during transportation. Measurement results showed that dissolved oxygen and temperature changed significantly with increasing seed density. However, pH did not show any significant differences between treatments. Overall, the results of this study indicate that shrimp seed density and water quality parameters are important factors to consider in the shrimp fry transportation system. Appropriate density management can minimize stress and mortality, and ensure seed survival during the distribution process.  

The South Korean entertainment industry, propelled by the global Hallyu wave, continues to thrive internationally. However, it remains influenced by deeply rooted patriarchal norms, especially in the portrayal of women in popular media. This study explores the representation of women in the film K-Pop Demon Hunters (2025) through the lens of Luce Irigaray’s postmodern feminist theory (1985). Using a qualitative content analysis approach, the research investigates the film’s visual, narrative, and symbolic dimensions to examine how female characters are depicted. Unlike the traditional portrayal of passive femininity prevalent in Korean popular culture, K-Pop Demon Hunters presents its female protagonists as active, autonomous, and empowered individuals. These characters express their identities through bodily performance, voice, dance, and emotion—an embodiment of écriture féminine, or feminine writing. The film introduces a symbolic language that allows women to speak from their own experiences, disrupting the male-dominated narrative structures often seen in mainstream media. Additionally, the film challenges patriarchal conventions by offering subversive and multifaceted representations of women’s bodies, relationships, and agency. Rather than reinforcing objectifying tropes, it constructs a space where feminine identity is fluid, expressive, and resistant to hegemonic definitions. This approach not only redefines the role of women within the cinematic narrative but also opens possibilities for alternative gender discourses in Korean media. In doing so, K-Pop Demon Hunters exemplifies how popular media can serve as both a mirror and a critique of societal gender norms.   

Durian is a tropical fruit belonging to the climacteric group, meaning it experiences a surge in respiration after harvest and quickly deteriorates. Due to its perishable nature, processing is necessary to extend its shelf life and maintain its nutritional value and flavor. One traditional method of processing that has long been known in Indonesia, particularly in Kalimantan and Sumatra, is the fermentation of durian flesh into tempoyak. Tempoyak is a natural fermentation product made from ripe durian flesh that has undergone a further ripening process and has a distinctive sour taste and strong aroma. The tempoyak fermentation process involves the activity of microorganisms, particularly lactic acid bacteria (LAB) such as Lactobacillus plantarum and Lactobacillus curvatus, which play a crucial role in producing flavor, a semi-solid texture, and functional health benefits. Human food needs depend not only on the quantity of food but also on the quality of its nutritional content, such as carbohydrates, protein, fat, vitamins, and minerals. In this context, fermented foods such as tempoyak provide added value in the form of probiotics that have the potential to improve digestive health. Lactic acid bacteria, which dominate the natural fermentation process, play a crucial role in the formation of flavor compounds and beneficial biological activities. This study aimed to isolate and identify the types of LAB present in traditional tempoyak from Jambi. Isolation was conducted to obtain pure strains of bacteria with potential probiotics, while identification aimed to determine the dominant bacterial species in the tempoyak fermentation process. The results of this study are expected to contribute to the development of functional food products based on local fermentation.

This study aims to identify the factors that influence the local community in developing the swallow nest business and to examine how the practice of swallow nest farming aligns with the principles of Islamic business ethics in Marioriwawo District, Soppeng Regency. The swallow nest industry has grown significantly in this area, shifting the economic landscape from primarily agricultural activities to a more diversified business sector. Before the emergence of this business, most residents were involved in farming. However, due to factors such as unpredictable harvests and unstable agricultural income, many community members have turned to swallow nest cultivation as an alternative and promising source of livelihood. According to Islamic business ethics, the practice of breeding swallows is permissible, as long as it does not involve cruelty to animals. This view is supported by the Indonesian Ulema Council (MUI) Fatwa Number 2 of 2012, which states that raising or cultivating swallows is allowed, provided the birds are not harmed or subjected to distress. Furthermore, the consumption and trade of swallow nests are also considered halal under Islamic law, adding to the business's appeal among the Muslim population. To explore the underlying motivations and social dynamics of this business shift, the study employed a qualitative research method. This approach was chosen to gain a deeper understanding of the local context, including the experiences, beliefs, and socioeconomic conditions of the people involved. The results revealed several influencing factors: the potential for high profit from selling swallow nests, the challenges faced in traditional agriculture (such as frequent crop failure), and the religious assurance that the business is acceptable under Islamic teachings. Overall, the swallow nest business represents a strategic and ethical economic opportunity for the community, enabling them to improve their livelihoods while staying aligned with their religious values.

Competition in the local culinary business is getting tougher as consumer behavior shifts, placing greater emphasis on product quality and social media recommendations. Nasi Uduk Pemuda, located in Doko Village, Kediri Regency, leverages brand trust, distinctive flavors, and promotions through social media influencers to drive consumer purchasing decisions. This study aims to analyze the influence of brand trust, flavors, and social media influencers on consumer purchasing decisions. The method used in this study is quantitative, with a survey of consumers who have purchased Nasi Uduk Pemuda products. The sample size was calculated using the Slovin formula. Data were analyzed using SPSS 29 through several tests, such as validity, reliability, classical assumptions, multiple linear regression, t-test, f-test, and coefficient of determination (R²). The t-test results indicate that brand trust and flavor have a significant positive influence on consumer purchasing decisions. On the other hand, the influence of social media influencers on purchasing decisions is positive, but not significant. The f-test shows that simultaneously, the three variables significantly influence purchasing decisions, with an R² value of 0.669. This means that 66.9% of the variation in purchasing decisions can be explained by brand trust, taste, and the influence of social media influencers, while the remainder is influenced by other factors not examined in this study. In conclusion, maintaining brand trust, ensuring consistent taste quality, and leveraging promotions through social media influencers remain important strategies in improving consumer purchasing decisions. Nasi Uduk Pemuda needs to continue to maintain and develop these three elements to remain competitive in an increasingly dynamic market.

Through seminars and leadership training, the goal of this community service project is to identify an effective leadership model that will enhance the work ethic of Jumantik employees in Setu Village, East Jakarta. Participating in the Effective Leadership program in enhancing work ethics were 100 Jumantik cadres from the village, the heads of the Development of Family Welfare of Setu Village, Cipayung District, and RW in the Setu Village neighborhood of East Jakarta. Lecture and coaching techniques are used in the training process. As a result of this training, a leader must employ effective leadership techniques to enhance work ethic when overseeing Jumantik cadres. To improve the motivation, accountability, and discipline of Jumantik cadres, one successful leadership model employs a transformational and participatory leadership style. This approach encourages open communication and fosters a sense of belonging among the cadres. It has been demonstrated that cadres who regularly monitor mosquito larvae perform better under leadership that offers clear guidance, emotional support, and active involvement in decision-making. Furthermore, the training emphasizes the importance of collaboration and teamwork, which are essential for achieving common goals. Jumantik cadre supervisors are advised to participate in leadership training since effective leadership would facilitate the development of a more inclusive and cooperative leadership model. Thus, it is anticipated that the effective sub-district eradication of Dengue Hemorrhagic Fever (DHF) will be facilitated by the adoption of the appropriate leadership paradigm, ultimately leading to healthier communities and improved public health outcomes. This is expected to make the public more vigilant and protected from potential online fraud in the future. Furthermore, increased legal literacy is expected to create a safer and more trustworthy digital transaction ecosystem for all parties.
