The Community-Based Drinking Water and Sanitation Provision Program, otherwise known as PAMSIMAS, is a rural drinking water and sanitation development platform implemented with a community-based approach. PAMSIMAS Officers of Wangon District, Banyumas Regency, currently provide pamsimas usage information, but the information used is still in the form of manual recording reports, so that when customers will see the total history of water use, the payment of usage that has been used is sometimes constrained by records that have been lost due to human error factors of officers. So it takes a pamsimas information system that can manage data well. The application development method uses a linear sequential model. This information system in the form of a web is expected to make it easier for officers and village communities to manage PAMSIMAS.
