Abstract. The community service program in Banjararum Village, Kulon Progo Regency is an activity to increase the Clean Water Supply and Improvement of Fisheries Products by the Rainwater Filled Pool Method combined with the installation of GAMA Rainfilter rainwater harvester. The program implementation process begins with installing the installations in July to October 2019 (3 months) at 3 location points, subsequently in October until December 2019 by harvesting rain and raising fish. The purpose of these activities are increasing productivity and development of aquaculture by using rainwater resources media, reducing the cost to purchase clean water in the dry season, utilizing rainwater for fisheries production and putting excess rainwater into society’s wells. Another goal is to form a habit to utilize rainwater in daily life and build a movement to harvest rainwater for raw water and fisheries. The implementation process of this program is using the roof of the house as the basis for catching rainwater which is channeled into a storage with a capacity of 1050 liters (1 m3) per location. The excess from the storage water is channeled into the people’s wells and into the fish ponds. The fish pond is made from iron wearnes with a diameter of 2 m. The test material used for productivity analysis with rainwater media is catfish (Clarias sp.), which amount 1000 per point. The recording results of the comparative process of catfish productivity with groundwater and rainwater media are carried out every month at 3 points of implementation, so that we can get an average percentage (%) level of aquaculture increasing and level of income that obtained. The result of the first phase are the installation of all equipment at all three locations and start raising the catfish in ordinary well water. While the next step will be carried out with rainwater from October to December.
