Mapping the position and attitudes of stakeholders towards the utilization of the black soldier fly using MACTOR Tools: A study in Depok City, West Java, Indonesia

Abstract

Abstract Depok City is located between the cities of Jakarta and Bogor. The population of the city has reached more than 2,000,000 people. This has consequences on the issue of waste, especially food waste. Food waste responsible for 8–10% of global anthropogenic greenhouse gas emissions. To support sustainable development, it is very important to reduce the amount of food loss. In 2019, food waste reached 931 million tons of food worldwide. Retailers and households are the biggest contributors to this waste at 13% and 61% respectively. This food waste exacerbates economic, environmental and social problems. The black soldier fly (BSF) insect (Hermetia illucens) can overcome the negative impact on the environment caused by food waste and at the same time can provide a sustainable source of protein. BSF larvae can digest food waste and convert it into biomass. However, the application of the use of the black soldier is not yet widely known in the City of Depok. For that, we need a comprehensive approach that involves various stakeholders. One of the most important elements in the successful application of the black soldier fly to the waste problems in Depok City is stakeholders mapping.
