Smart-eco farming villages for low carbon sustainability: Evidence from an Indonesian living lab

Decarbonizing smallholder agriculture rarely hinges on a single technology; it depends on whether farmers can reorganize everyday routines without increasing production risk. We report monitored evidence from the Tawangargo Smart-Eco Farming Village (TAMENG) program in East Java, Indonesia (2022-2026), a CSR-supported community living lab initiated by PT Petrokimia Gresik. Using an embedded qualitative case study complemented by descriptive monitoring records, we trace two linked intervention packages: (i) circular management of horticultural residues into liquid organic fertilizer (POC) and livestock feed concentrate (wafer) and (ii) precision irrigation (drip systems and growth-stage scheduling). Program logs indicate that = 1,095 tons of organic residues are processed annually, yielding =39.4 tons/year of POC and supporting a program- estimated mitigation of =555 tCO2-e/year through avoided unmanaged decomposition and partial substitution of upstream inputs. Irrigation pilots report water-use reductions up to 65%, with practical co-benefits for pumping time and input-related energy demand. We also describe the governance mechanisms that sustained adoption Agronova Vision as a cross-group platform and a Resource Center (P4S Ngudi Kaweruh) that anchors training, quality assurance, and replication. The case suggests that village-scale CSA living labs can connect solid-waste resource utilization with water efficiency and livelihood resilience, while keeping emissions claims transparent and conservative.
