Where the current system often finds difficulties when searching for population data, duplication of data is found as a result of ordered population data collection and the occurrence of damage and data loss as a result of the existing storage media only in the form of documents. The purpose of this research is to design a population data processing application in Cengal village. The system development method used is the waterfall method with PHP and MYSQL scripts as database managers.
