There are still not many SMP/MTs/Equivalents in Indonesia holding online New Student Admissions, one example being MTsN 4 Kab. Lima Puluh Kota under the auspices of the Ministry of Religion Kab. Lima Puluh Kota. During manual PPDB at MTsN 4 Kab. Lima Puluh Kota there are several obstacles both experienced by the school, prospective students and parents, both in terms of administration or information at the time of PPDB implementation. Another problem that arises is the distance of the radius and distance of students who will register to school; from the data, the authors found that the radius and the furthest distance traveled by students was ± 18-20. It is the author's background in designing an Android-based PPDB information system using the 4D version of the R&D method with the SDLC waterfall system development model.
