Penerapan Teknologi Tepat Guna Berbasis Ekonomi Sirkular dalam Mendukung Desa Rendah Karbon dan Ketahanan Pangan

Abstract

Food waste has emerged as a critical issue in Indonesia, contributing significantly to national waste generation and carbon emissions. According to the United Nations Environment Programme (UNEP, 2024), food waste in Indonesia reached 77 kg per capita per year, equivalent to approximately 20.9 million tons in 2022. Cibanteng Village, located in Ciampea Sub-district, Bogor Regency, is among the areas facing this challenge, with food waste generation estimated at more than 319 tons per neighborhood unit (RW) annually (Melati, 2022). In response, the second year of this community engagement program focused on strengthening the application of circular economy principles through appropriate technology across three main pillars: Black Soldier Fly (BSF) maggot cultivation, chili farming using drip irrigation, and tilapia aquaculture with a molasses-free biofloc system. The activities included socialization, training, technology application, mentoring, and evaluation, involving Kebon Kopi Mandiri Farmers’ Group and Pabuaran Hijau Community. Technological innovations such as a pedal-powered maggot sifter, four-tier biopond racks, and drip irrigation successfully optimized the use of limited land. The implementation of molasses-free biofloc integrated with maggot-based feed further strengthened the link between aquaculture and organic waste management. Beyond technical aspects, digital marketing training improved participants’ knowledge in branding strategies, market segmentation, and distribution. This program has contributed to enhancing product value, expanding market access, and strengthening community food security based on a sustainable circular economy, while simultaneously supporting the achievement of SDGs 2 and 12.
