The schedule needs to be adequately organised, so we need an innovative method. The research that resulted in the development of this system was conducted using the waterfall methodology. The learning scheduling application and value data processing at SMK Negeri 1 Tulang Bawang Tengah were designed and developed utilising the waterfall technique, comprising four stages: analysis, design, coding, and testing. The results of black box testing applied to application testing show that the design matches expectations.</p> Genis Priyantoro Rangga Firdaus Doni Andra Hery Dian Septama Copyright (c) 2022 Afif Rahman Riyanda, Novi Hendri Adi, Army Trilidia Devega https://creativecommons.org/licenses/by-nc-sa/4.0 2022-11-26 2022-11-26 2 2 1 13 10.23960/josst.v2i2.28
