Organic waste management at Yogyakarta International Airport (YIA) is still not optimal, even though organic waste production averages 1,264 kg per month. This community service activity aims to develop technological innovations through the utilization of eggshell waste and Black Soldier Fly (BSF) maggots into economically valuable pellet feed products. The activity was carried out from October 8 to 15, 2025, involving three workers from the Temporary Processing Site (TPS) of PT Angkasa Pura Indonesia YIA. The implementation methods included an initial survey, education, demonstration of pellet production, and evaluation of participants' skills and product quality. The production process involved drying, grinding the ingredients, mixing the ingredients, molding, and drying the pellets. The results showed that the workers were able to independently carry out the production process and produce pellets with good physical quality. Cost analysis showed that the cost of production was IDR 47,989/kg, with a potential profit margin of 30% and an estimated return on investment within ±7 months. This innovation has proven effective in reducing waste volume, increasing the added value of organic waste, and supporting the principles of zero waste and circular economy in the airport area. This program has the potential to be further developed as a model for sustainable organic waste management.

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.  

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.

Maggots are larvae of the Black Soldier Fly (BSF) which have benefits as waste decomposers and have high potential as feed ingredients. This study aims to analyze the effect of power and time on maggot drying using microwaves. Using the Computational Fluids Dynamics (CFD) method on microwave heating with a power of 2000 watts and 2500 watts, and a residence time of 10 minutes, 20 minutes, and 30 minutes, then the final maggot temperature was tested. The results showed that the final temperature of the maggot tended to increase with increasing power and residence time. This happens because high microwave power provides large energy in a very short time. This energy is efficiently absorbed by maggots through the mechanism of dipole rotation and ionic conduction, causing molecules to vibrate and rub with high intensity. The final temperature of the maggot is between 110oC-125 oC with the highest temperature at a power of 2500 and a drying time of 30 minutes.

Organic waste management is an important issue in addressing environmental problems. One potential solution is bioconversion technology using Black Soldier Fly (BSF) maggots that can break down organic waste and produce larvae with economic value as animal feed. To increase the selling value and extend the shelf life, BSF larvae need to be dried using tools such as rotary dryers. This study aims to design and analyse the strength of a rotary dryer machine frame for maggot drying with a Finite Element Analysis (FEA) approach based on SolidWorks software. Simulations were carried out on several materials: ASTM A36, AISI 1020 Steel, and AISI 1045 Steel. The analysis results show that all materials are within safe limits based on Von Mises stress, deformation, and safety factor. AISI 1045 steel material gives the best performance with Von Mises stress of 14.238 MPa, deformation of 0.59 mm, and safety factor of 7.2. These results show that AISI 1045 steel is the most recommended material for the rotary dryer frame.

Suboptimal waste management in Kalijoso Village, Secang District, Magelang Regency, is a critical issue that impacts environmental sustainability and public health. The inefficiency of conventional waste disposal methods has led to increased waste accumulation, soil and water pollution, and the spread of diseases, which has significant consequences for local communities. To address these challenges, the local government and community organizations have embraced the principles of the 3R (Reduce, Reuse, Recycle) through a transformation of traditional waste disposal sites (TPS) into 3R TPS. The new approach focuses on sustainable waste management practices that reduce the amount of waste sent to landfills. One of the key strategies implemented is educational outreach to raise awareness about the importance of waste segregation and recycling. Additionally, training programs have been conducted to teach the community how to process organic waste, particularly through the cultivation of maggots using Black Soldier Fly (BSF) larvae. This method not only helps reduce the volume of organic waste but also provides a practical solution for transforming waste into valuable resources. The maggots cultivated during the demonstration are used as animal feed, which creates a sustainable circular economy within the community. Furthermore, composting organic waste results in high-quality compost that supports local agricultural activities. This has added economic value by reducing the need for chemical fertilizers, while simultaneously improving soil health. The role of the Salakan Hamlet Youth Organization has been instrumental in this initiative. They have successfully managed a waste bank, providing an organized and systematic approach to waste collection and recycling. This initiative has fostered a sense of community responsibility and has not only improved waste management practices but also contributed to the overall economic development of the village.

Utilization of fermented layer chicken excreta as a feed medium for Black Soldier Fly (BSF) maggots is a sustainable solution for organic waste management. Chicken excreta contains 13-32% crude protein, but has disadvantages such as unbalanced nutrient composition and unpleasant odor. Fermentation of chicken excreta can improve maggot production performance by reducing pathogens, odor, and facilitating digestion. The growth medium of 50% excreta + 50% tofu dregs produced the highest PK, which was 34.34%. The lowest SK and LK were obtained from the growth medium of 50% excreta + 50% tofu dregs and 25% excreta + 75% tofu dregs. Based on physical conditions, the longest and heaviest maggot sizes were obtained from the growth medium of 50% excreta + 50% bran + 5 ml EM4. Meanwhile, the shortest maggots were obtained from the growth medium of 75% coconut dregs + 25% excreta and the lightest maggots were obtained from the growth medium of 100% excreta.

Food waste is a global issue that continues to be discussed. This is because the problem of food waste can have an impact on the environment, health and climate. Through the Sustainable Development Goals (SDGs) initiative, creating a sustainable community through food waste management is made a top priority. This article discusses the implementation of the Zero Food Waste program at SDN Ekologi Kahuripan Padjajaran using the Black Soldier Fly (BSF) maggot bioconversion approach. This community service was carried out by P3K UPI Purwakarta students who collaborated with TPS 3R Ciseureuh Purwakarta to manage food waste. This service activity is carried out through several stages which include preparation, implementation and evaluation, involving students and their parents in managing organic waste. The results of bioconversion are maggots and organic fertilizer which will be used into products with economic value. This program has succeeded in increasing environmental awareness, reducing food waste, and can create sustainable solutions in managing organic waste. It is hoped that this article can make recommendations for implementing similar methods in other areas as an environmentally friendly waste management model.

Utilizing white pepper peel waste (Pipper nigrum L.) as compost can minimize the problem of pepper peel waste. This research uses black soldier flies (BSF), the results of which are maggots as fertilizer for the growth of potpourri tomato plants (Lycopersicon pimpinellifolium). The aim of this research is to determine the quality of compost from white pepper skin waste resulting from bioconversion using BSF, and its effect on the growth of potpourri tomato plants. This research used an experimental method by pre-fermenting white pepper skin waste using 50 ml EM4 for 2, 3, 4 weeks and then using it as food for BSF larvae. Next, the cassava results are applied to potpourri tomato plants with P1 (1 kg of soil: 5 kg of cassava 2 weeks), P2 (1 kg of soil: 5 kg of cassava 3 weeks), P3 (1 soil: 5 kg of cassava 4 weeks), P4 (1 kg : 10 kg cashgot 2 weeks), P5 (1 kg : 10 kg cashgot 3 weeks), P6 (1 kg : 10 kg cashgot 4 weeks) and control (soil without cashgot). The data were analyzed using ANOVA via the SPSS 26 application. The cassava application showed that there was a significant effect on the highest plant height P6 (22.98 inches), the highest stem diameter P1 (4.58 mm), the highest number of leaves P3 (108.67 leaves), the highest fruit diameter was P2 (17.97) and the highest fruiting time was P0 (29.75). The highest number of fruit is P1 (13 fruits/plant), the highest fruit weight is P5 (39 grams/plant). In conclusion, P1 treatment is the best quality compost for the growth of potpourri tomatoes which is thought to have N (0.22%), P (0.15%), K (0.01%), C-organic (5.84) and a C/ N (26.5).
