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.

One method of drying Black Soldier Fly (BSF) larvae that can be applied is drying using a continuous microwave oven. This tool utilizes microwaves emitted to evaporate water. In addition, the use of a conveyor that runs on a microwave oven as a medium or place to place BSF larvae is expected to simplify the production process. This study was conducted to determine the design and strength analysis of the thermal structure of a continuous microwave oven-type BSF larva dryer using Solidworks software. The specifications of the continuous microwave oven-type BSF larva dryer have a capacity of 15 kg, a heating input power of 8 KW and a temperature of 100℃. With variations in heating time of 20, 30, and 40 minutes. The results of the thermal structure analysis of the BSF larva dryer type continuous microwave oven based on the simulation obtained stress with the highest value of  and the lowest value of . The results of the displacement simulation with the highest value of  and the lowest value of . The Safety factor simulation result is 3.2. So from the simulation results it can be said that it is safe to continue to the manufacturing process.

This study aims to determine the phytochemical content of Black Soldier Fly (BSF) larvae extract, also known as Hermitia illucens. The maceration method with 96% ethanol solvent was used for extraction, followed by evaporation using a rotation evaporator. Qualitative phytochemical tests were carried out to identify compounds such as alkaloids, flavonoids, saponins, terpenoids, polyphenols, steroids, and triterpenoids. The results showed that BSF maggot extract contained alkaloid and flavonoid compounds that were positively detected, while other compounds were not detected by the method used. The alkaloid and flavonoid content has antimicrobial, anti-inflammatory, and antioxidant properties. These results indicate that BSF larvae can function as a source of natural biopharmaceutical active ingredients. However, the type of solvent used and the process conditions used affect the success of the extraction.

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.

Socio-economic action activities aim to increase participants' awareness of the importance of social and environmental roles through educational and participatory approaches. This study aims to describe the implementation of the activity of feeding maggot to chickens as a form of organic waste utilization and the activity of decorating bokor as a preservation of local culture. The method used was participatory observation, where participants were directly involved in both activities. The results showed that participants understood the benefits of maggot as a waste management solution and alternative feed, and showed high enthusiasm in decorating bokor as a form of preserving cultural values. This activity was able to increase social, environmental, and cultural awareness in participants in an integrated manner in one series of activities.

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.

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.

Organic waste is an environmental problem, especially in the villages of Pandeyan, Grogol, Sukoharjo, so there is a need to solve this problem through direct community activities. One solution is the socialization activity on organic waste processing through magot cultivation in Pandeyan village. With this socialization, it is hoped that the community will gain further understanding regarding magot cultivation as an effort to process household organic waste to make it more useful. The socialization activity was conducted at the Pandeyan village office on August 30, 2023. To measure the success of socializing organic waste processing through magot cultivation, an evaluation was carried out using a questionnaire method distributed to participants. From the questionnaire results, it was found that 88.9% of the total participants understood magot cultivation. Meanwhile, if you look at the potential of organic waste in each household participating in this socialization, it is possible to process it through magot cultivation. However, there is still a need for assistance and further understanding regarding magot cultivation because there is still a stigma that maggots have a maggot-like shape and are not suitable for cultivation.
