Abstract

Penelitian ini bertujuan untuk mengembangkan perangkat berbentuk program (perangkat lunak) untuk komputer dengan model pengembangan jenis Unified Process (UP). Pengembangan ini memerlukan program Microsoft Visual Studio Enterprise 2019 (Visual Basic.Net) dengan MySQL Workbench 8.0 CE sebagai database. Setelah program dibuat, program ini dilakukan uji unit, integration, validation (alpha and beta testing) dan system testing. Berdasarkan hasil pengujian, program ini dinilai sangat layak. Pengujian unit dan integration mencapai tingkat keberhasilan 100%. Hasil validation testing menunjukkan angka V = 0,95, dianggap memadai. Terakhir, hasil system testing menunjukkan rata-rata maintainability index sebesar 63,16 (daerah hijau) dan navigasi berfungsi mencapai 100% saat dijalankan.

Abstract

This study aims to test the feasibility of the test instrument as a measuring tool for student knowledge of alkane compounds in the online form of 15 multiple choice questions on the concept of characteristics, physical properties, and nomenclature of alkanes. The questions were tested on 85 students who had studied the subject of alkanes. The feasibility analysis includes the level of problem difficulty, construct validity, content validity, and reliability. The results of the analysis show that the items developed are feasible according to the Rasch model.
