Waste processing is still a big problem in various developing countries, including Indonesia. The community produces more and more waste every day, but the current solution still uses the method of landfilling the waste at the Final Processing Site (TPA). Therefore, there is a need for a solution for processing organic waste.
Therefore, in one of the efforts to handle and process organic waste, the Lecturer Community Service Team, together with students from the Industrial Chemical Engineering Technology Study Program (TRKI) at the Diponegoro University Vocational School (SV UNDIP), held an organic waste processing training at SMKN 3 Kendal using the Black Sldier Fly maggot medium ( BSF). This activity is an implementation to support the Sustainable Development Goals (SDGs). The lecturer service team is Mohamad Endy Julianto, S.T., MT., Anggun Puspitarini Siswanto, S.T., Ph.D., and Hermawan Dwi Ariyanto, S.T., M.Sc., Ph.D., along with students: Deas Oky Pratama, Malika Pintanada Kaladinanty, and Nisa Eka Rahmania. This training aims to deal with organic waste as a means of education and community empowerment. For this reason, the resource speakers and the implementation of the training are delivered by students as part of the MBKM learning so that they can perform.
Malika Pintanada Kaladinanty, the student coordinator, who is usually called Malika, said that the training was held at SMKN 3 Kendal, a partner of the Undip Vocational TRKI Study Program. The training includes exposure related to maggot-based organic waste management systems by means of biological decomposition, organic waste decomposition processes, reducing waste volume, and utilization into organic fertilizer and animal feed. Malika added that maggots are the larvae of black soldier flies, also known as BSF (Black Soldier Fly). BSF is a type of fly that has benefits for humans and does not cause disease. Maggots are usually used for animal feed purposes. Maggot contains 43.42% protein, 17.24% fat, 18.82% crude fiber, 8.70% ash, and 10.79% air, so it can be used as an alternative animal feed protein.
Maggots have the ability to degrade organic waste better than other insects. The residue from the bioconversion of organic waste using maggot is cassava, which can be used as compost in vegetable cultivation. Maggot cultivation is the right solution to solve the problem of organic waste in society, said Malika. Malika explained that the life cycle of BSF is the same as that of other Diptera insects, starting from eggs hatching to larvae, which undergo a metamorphosis process to become pupae and adult insects. The BSF metamorphosis cycle takes place in approximately 40 days, depending on the temperature and humidity where the BSF lives, and the nutritional intake it eats. The principal of SMKN 3 Kendal, who is usually called Pak Malik, hopes that this program will be beneficial for both parties, both in terms of research and further development. Apart from being a form of collaboration between study programs and the wider community, this service is also a form of responsibility for the entire academic community in welcoming the Tri Dharma of Higher Education, namely education, research, and community service.
The hope is that this action as a solution for maggot cultivation training or BSF (Black Soldier Fly), can be useful in dealing with organic waste and can be fully utilized in various fields, such as the potential for producing organic fertilizer and animal feed. This, of course, can also have a positive impact on the economy, concluded Malika.
