Abstract
E-diagnostic Assessment is a diagnostic test instrument based on the mersics.com website which is used to determine students' initial level of understanding before carrying out physics learning. The aim of this research is to determine the level of validity and reliability of the development of mersics.com as an e-diagnostic assessment on the prerequisite material for the kinematics chapter. The limited trial subjects in this research were 75 class XI MIA students. Validity analysis uses the Item Response Theory (IRT) approach with one Logistic Parameter (PL), namely the difficulty level parameter or better known as the Rasch Model. The research results showed that 56 questions were declared valid by experts using Content Validity Ratio (CVR > 0) analysis. Meanwhile, the results of the analysis based on the Rasch Model showed 20 valid questions in the Understanding of Motion sub-chapter, 9 valid questions and 1 invalid question item in the GLB and GLBB sub-chapters, 10 valid questions in the Parabolic Motion sub-chapter, 9 valid questions and 1 the question item is invalid and in the Circular Motion sub-chapter. The reliability of the questions as a whole is declared reliable. So that, It can be concluded that this E-diagnostic Assessment is suitable for use in physics learning.

| Additional Information: | E-diagnostic Assessment merupakan sebuah instrumen tes diagnostik berbasis website mersics.com yang digunakan untuk mengetahui tingkat pemahaman awal peserta didik sebelum melaksanakan pembelajaran fisika. Tujuan penelitian ini adalah untuk mengetahui tingkat validitas dan reliabilitas instrumen dari pengembangan mersics.com sebagai e-diagnostic assessment pada materi prasyarat bab kinematika. Subjek uji coba terbatas dalam penelitian ini adalah siswa kelas XI MIA berjumlah 75 orang. Analisis validitas menggunakan pendekatan Item Response Theory (IRT) dengan satu Parameter Logistik (PL) yakni parameter tingkat kesukaran atau lebih dikenal dengan Rasch Model. Hasil penelitian menunjukkan bahwa terdapat 56 butir soal dinyatakan valid oleh para ahli dengan analisis Content Validity Ratio (CVR > 0). Sedangkan hasil analisis berdasarkan Rasch Model menunjukkan 20 butir soal valid pada sub bab Pengertian Gerak, 9 butir soal valid dan 1 butir soal tidak valid pada sub bab GLB dan GLBB, 10 butir soal valid pada sub bab Gerak Parabola, 9 butir soal valid dan 1 butir soal tidak valid dan pada sub bab Gerak Melingkar. Reliabilitas soal secara keseluruhan dinyatakan reliabel. Sehingga, dapat disimpulkan bahwa E-diagnostic Assessment ini layak digunakan pada pembelajaran fisika. | |||||||||
