Waste and pollution are two important issues in the small industry of coffee production despite of the equipment and capital constraints. The green productivity method is able to reduce the waste generated through the efficient use of resources, low operating costs, environmental management, and productivity improvement. This study is aimed to formulate an alternative environmental management as well as to improve the productivity of small industry of coffee production. The results showed that the Environmental Performance Indicator (EPI) index was negative at -621.229 which means that environmental performance was below the standard. The alternative green productivity generated was: 1) by operating pulper machine with capacity of 125 kg/hour and power 2.2 kW; 2) by designing water immersion tub for coffee sized 2.4 x 1.2 x 0.85 m with capacity of 2.45 m3. Based on NPV analysis, it obtained that the alternative 1 showed financial analysis as 28.130, 271.61 IDR with productivity increase estimation as 171% and wastewater reduction efficiency as 0%. While the alternative 2 showed the NPV analysis as 40.224.591,11 IDR with productivity increase estimation as 163% and wastewater reduction efficiency as 30%. © Global Science Publications.
