<![CDATA[The community of Air Anyir Village faces structural challenges: heavy reliance on unsustainable tin mining and low agricultural productivity caused by acidic, marginal land. This study analyzes the effectiveness of the BAHTERA PETAPA program, initiated by PT PLN Nusantara Power Services (PLTU Bangka), in addressing these vulnerabilities and assesses its contribution to the local community. A mixed-methods approach (qualitative and quantitative) was applied within the Asset-Based Community Development (ABCD) framework, which covers asset identification, mobilization of potential, and sustainable asset management. Primary data were collected from 50 key informants and through laboratory testing. The program successfully integrated the intensive duck farming of the "Taret Jaya" group with the production of "Baratani" fertilizer from FABA (Fly Ash and Bottom Ash) by the "FABA Kite Lestari" group. Its effectiveness is evidenced by a 200% increase in chili productivity (from 1 to 3 tons/ha), a 50.6% reduction in fertilizer costs, an improvement of soil pH to near-neutral (7.79), and a greenhouse gas emission reduction of 0.000092 Gg CO₂e/year. The program's sustainability is further reinforced legally by Village Head Decree Number 141/61/SK/2008/2025, which formalizes the community's livelihood transition toward institutionalized food self-sufficiency.]]>
