The objectives in this paper are to analysis the requirement of system design green productivity oyster mushrooms supply chain, to select the important attributes and to determine development strategies for increased green productivity. In order to analyze the requirement system, use case diagram and Business Process Model and Notation (BPMN) were used in this paper. Relief method was used to select the important parameter attributes which sufficiently describe environment variables affecting the upstream and downstream supply chain of oyster mushroom. Then, to establish the rule in the formation of strategy formulation, Association Rules Mining was applied. The results are analysis in this paper system with BPMN business flow diagram can describe the system more easily. Relief method shows that the most important economic variable is sawdust. Association Rules Mining shows that economic variables with high corn and high ring was produced low sawdust with 100% confidence level and support value of 0.167 This research is expected to facilitate prediction of strategy to increase productivity oyster mushroom agroindustry based on existing environment condition. KEYWORDS: Association Rules Mining, Green Productivity, Oyster Mushrooms, Relief, Supply Chain INTRODUCTION The development of the oyster mushroom industry is currently growing rapidly along with the changing paradigm of people in consuming fruits and vegetables. Consumer demand in vegetable consumption can only be met by oyster mushroom farmers by 2015 amounting to 3% of total demand for vegetables in Indonesia (Direktorat Jenderal Bina Produksi Hortikultura 2015). In this case the company is required to continue to improve performance in order to compete with various other agroindustries. Along with the increase of production, have many environmental problems. The problem is caused by the production process often result in the disposal of materials and Emision that will burden the environment, whereas good production processes not only attention to the safety and side effects of waste waste process, but also reduce waste generated. This problem is also often ignored by the oyster mushroom agroindustry, whereas now the environmental issues become quite warmly discussed. Therefore, it is very important for oyster mushroom agroindustry attention to environmental aspects in each production process implemented in order to create suitability with the surrounding environment, and also organic agriculture should sustain and enhance the health of soil, plant, animal, human and planet as one and be indivisible. It should be based on living ecological systems and cycles, work with them, emulate them and help sustain them (Adiprasetyo et al. 2015). To improve productivity while reducing environmental impacts, the Green Productivity method can be an approach to help companies deal with existing problems. Thus, the application of this method is expected to increase productivity by minimizing waste and reduce the impact on the environment. Green productivity (GP) is a strategy to increase company productivity and environmental performance simultaneously in overall socioeconomic development (Asian Productivity Organization 2001). Green productivity is an application of the right techniques, technology and management system to produce environmentally friendly products or services. GP reconciles two needs that are always in conflict, namely the business needs to generate profit and the needs of everyone to protect the environment. GP is not just an environmental strategy, but a total business strategy. In fact, that when GP is implemented, companies will experience productivity improvements through reduced spending on environmental protection, such as resource
