Model Pengelolaan Sumber Daya Air Pada Pulau Kecil Menggunakan Pendekatan Eko-Drain (Studi Kasus: Pulau Merbau Kabupaten Kepulauan Meranti)

The unavailability of sufficient water sources to meet the needs of clean water consumption is a problem in developing water resources on a small island. Brownish swamp water tends to contain organic compounds and surface water tends to be salted by sea water. Peat and sea water treatment requires relatively expensive investment, operational costs, and maintenance. Excess water in the rainy season with high rainfall intensity while the short duration of rain causes the rain water does not have time to seep into the ground so that it is wasted in the sea. Using an eco-drain approach is an effort to overcome the water crisis using economic investment and maintenance costs by making simple technologies to accommodate excess water during the rainy season which is then used for various purposes when water is needed. The objectives of this study are to: (1) Analyze the existing conditions of the needs and availability of rainwater as clean water on Merbau Island, (2) Assess the water supply strategy on Merbau Island and (3) Develop a rainwater harvest management model for clean water on Merbau Island. A total of 100 respondents were taken as samples using simple random sampling. A total of 100 respondents were taken as samples using simple random sampling. Data is used to fulfill the analysis of the first objective. Then 5 experts determined purposively are drawn from experts who understand the management of water resources. The Analytical Hierarchy Process (AHP) is used to analyze the second objective, which is to obtain a strategy for providing clean water on the island of Merbau. Based on the analysis of two research objectives, the rainwater harvesting management model for clean water is regulated on Merbau Island using the Water Balance method.The results showed that the availability of clean water was still lacking because the only source of clean water was rainwater. The rainwater collection system owned by the community is inadequate to optimally collect rain water. Strategies to meet water shortages are carried out by maximizing individual scale rainwater storage. The model offered for the roof area is 168 m2, the number of family members is 6 people, the need for clean water per person is 60 liters / day, so we need a reservoir for 13 m3. The availability of storage tanks is able to meet the needs of clean water for one year from January to December.
