Multi Effect of Rain Harvesting in the Floating Village of Malahing on the Coast Bontang Developed by the CSR of PKT

Abstract

The residents of the floating village of Malahing, Bontang, East Kalimantan, earn their living as fish catching fishermen and seaweed farming. Residents even experience a clean water crisis, every month they require a budget IDR 300, 000 until IDR 400, 000 to buy clean water at Tanjung Laut by ketinting. The PKT programmed rain harvesting for Malahing residents to supply clean water. The method used was field observations and surveys as well as simple calculations using the program of Office Excel. The PKT carried out gutter procurement for every resident’s house, provided three plastic drums of 200 litres to collect rainwater, provided filters to filter rain water, train the residents to care for and repair the filters. As a result, the residents get clean water to meet their daily basic, grow vegetables for family needs and do greening in their yard and water them. They can also water communal latrines so that defecation is not carried out at sea. Malahing residents can save IDR. 356, 000 until IDR 456.000 per month, help save fossil fuels and reduce carbon dioxide emissions so they become healthier, prosperous and environmentally friendly.
