Uji Validitas dan Reliabilitas Instrumen Penelitian Tingkat Pemahaman Teks Prosedur
Abstract
Abstrak—Uji validitas dan reliabilitas alat ukur sangat penting dalam dalam dunia pendidikan, terutama untuk menilai seberapa baik siswa memahami teks prosedur. Instrumen penelitian yang valid dan reliabel diperlukan untuk mengukur kemampuan pemahaman teks prosedur dengan tepat. Penelitian ini bertujuan untuk menguji validitas dan reliabilitas instrumen yang digunakan untuk mengukur tingkat pemahaman teks prosedur. Penelitian ini adalah penelitian kuantitatif. Subjek di dalam penelitian ini adalah 2 guru sebagai validator butir instrumen tes dan siswa kelas VII pada sekolah SMPN 3 Kedungadem. Penelitian ini berhasil mengembangkan alat untuk menilai pemahaman siswa tentang teks prosedur di SMPN 3 Kedungadem. Uji validitas menunjukkan semua item soal sangat valid, dan reliabilitas instrumen baik dengan nilai Cronbach's Alpha 0,869. Temuan ini menekankan pentingnya validitas dan reliabilitas dalam pendidikan untuk data yang akurat. Pengembangan lebih lanjut diharapkan dapat meningkatkan kualitas pengajaran Bahasa Indonesia di sekolah.

Abstract—Testing the validity and reliability of measuring instruments is very important in the world of education, especially to assess how well students understand descriptive text. Valid and reliable research instruments are needed to measure the ability to understand procedural texts correctly. This research aims to test the validity and reliability of the instruments used to measure the level of understanding of procedural texts. This research is quantitative research. The subjects in this research were 2 teachers as test instrument item validators and class VII students at SMPN 3 Kedungadem school. This research succeeded in developing a tool to assess students' understanding of procedural texts at SMPN 3 Kedungadem. The validity test shows that all question items are very valid, and the reliability of the instrument is good with a Cronbach's Alpha value of 0.869. These findings emphasize the importance of validity and reliability in education for accurate data. It is hoped that further development can improve the quality of Indonesian language teaching in schools.
