In Bogor City, the problem of organic waste is worsening, and household food scraps constitute the largest portion.
This research investigates the application of Pentahelix model—collaboration between government, private sector,
academia, civil society and media—for managing organic waste using Black Soldier Fly (BSF) maggot farming. With
a qualitative case study design, the study was conducted from March to May 2025 through interviews and direct
observations with Bumi Farm, Siliwangi Waste Bank and Bogor City Environmental Agency. Findings underscore
the cooperative contributions of different stakeholders towards valorization of waste into animal feed, organic
fertilizer, and antiseptic oils. It was found that collaboration of various stakeholders based on Pentahelix approach
does not only enable effective sustainable waste management but also drives innovative circular economy on a shared
responsibility basis. The study suggests this approach as a strategic guide for tackling comparable issues in urban
settings.
