Abstract
Clean water provides an essential role for all living things to stay alive. However, the availability of freshwater in Indonesia is insufficient to fulfill the total need for clean water, especially in a drought. One of the alternative sources of freshwater in Indonesia is rainwater. The simple filtration is a filtering technology with a variety of media (sand, gravel, activated carbon). This research proposes to develop rainwater filtration utilization from a pure material that very easy to found. A literature study from several studies is conducted regarding the use of rainwater as clean water with the filter made from simple stuff to improve access to the freshwater by utilizing simple filtration technology. The step of simple filtration technology development is rainwater collection, and then it is filtered using the filter media. This filtration consists of quartz sand, gravel, fibers/baffle, and charcoal with various types and heights. The standard parameter of the water quality used in this study is based on the Ministry of Health Regulation No.416/Menkes/Per/IV/1990. The results of this study are the composition of gravel filter media, zeolite, activated charcoal, sand, and sponges with total thicknesses is 105 cm and the time needed to carry out the filtration for 10-15 minutes to shows the potential of rainwater as a source of clean water which compatible with standards quality to fulfill the daily needs. The thicker of the filter media will result in cleaner water, but it requires a longer time.
