Abstract

Food waste is a major issue in Indonesia, accounting for 41.97% of waste generated. This untreated waste can lead to the production of greenhouse gases. However, food waste has the potential to be composted due to its high nutrient content. The purpose of this study was to analyze the technical feasibility of processing food waste using the Black Soldier Fly (BSF) composting method for organic fertilizer production. The study used variations of fish waste and reject milk as composting mixtures, with percentages of 100% food waste, 70% food waste and 30% cow manure, and 30% food waste and 70% fish waste. The dimensions of the BSF composting reactor were 56 cm x 43 cm x 20 cm. The research was conducted for 15 days with the addition of local microorganisms (MoL) to accelerate the degradation process. Various parameters such as pH, moisture content, C-Organic, nitrogen, phosphorus, and potassium were analyzed. The results showed that all variations met the required compost quality standards, it which was technically feasible to be used as organic fertilizer using the BSF composting method. The results of this study can improve the circular economy because compost and bsf larvae products have many benefits if traded.

Abstract

Politeknik Perkapalan Negeri Surabaya has workshops or laboratories that generate hazardous waste from practical learning activities. Currently, hazardous waste is not stored in accordance with regulations, it will pose a danger to the environment and human health. Therefore, this research requires a design for hazardous waste storage that complies with the Minister of Environment and Forestry Regulation number 6 of 2021. The design of fire extinguisher requirements is based on the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia No. Per.04/Men/1980 and the design of lighting based on SNI 03-6575-2001. This research discusses the design of hazardous waste storage, including the characteristics of hazardous waste, the design of packaging and the supporting facilities. The characteristics of hazardous waste at the Politeknik Perkapalan Negeri Surabaya consist of flammable waste, toxic waste, and infectious waste. While, the packaging for hazardous waste is equipped with symbols and labels according to their characteristics and volume. The design of the hazardous waste storage building at the Politeknik Perkapalan Negeri Surabaya has dimensions of 11 m x 7 m, equipped with 12 lights and light fire extinguishers, taking into account the location, facilities, and emergency response.
