RANCANG BANGUN KALKULATOR BARISAN DAN DERET DENGAN METODE KANBAN

Abstract

The lack of students' understanding of the material for sequences and series often results in confusion about how to work on sequence and series questions. In addition, students are also sometimes not careful in calculating sequences and series questions. To overcome these problems, the authors designed an Androidbased application that can perform calculations and work on sequence and series problems, including how to solve them. As well as in this application, learning materials for sequences and series are available which are useful for increasing students' understanding of sequences and series. In this study, the authors collected problem data through observation, interviews, and questionnaires. The system design method that the author uses in this study is the kanban method, by dividing each step of the process into three parts, namely the requirements, develop, and test sections. To design the author's system using the UML (Unified Modeling Language) modeling tool and to create the interface design the author uses a wireframe. Meanwhile, to implement the author system using the Android Studio software. In system testing, the authors tested the system through two stages of testing, namely internal testing and external testing. Internal testing was carried out by the author himself using the black-box testing method. Meanwhile, external testing was carried out by students and mathematics teachers.
