Abstract

Kandungan ikatan azo dalam zat pewarna tekstil remazol red mengakibatkan zat warna lebih mudah larut dalam air dan memiliki stabilitas yang tinggi. Hal ini menyebabkan limbah tekstil memerlukan penanganan khusus agar aman dan tidak memberikan dampak negatif ketika dilepas ke perairan. Salah satu cara alternatif untuk menangani limbah non-degradable adalah dengan menggunakan metode fotodegradasi dengan bantuan fotokatalis. Penelitian ini bertujuan untuk membandingkan aktivitas reaksi fotodegradasi remazol red dengan fotokatalis TiO2 anatas 50%-rutil 50% dan TiO2 anatas tersupport AgI. Proses fotodegradasi Remazol red dilakukan dengan memvariasi fotokatalis yang digunakan yaitu fotokatalisis TiO2 anatas 50%-rutil 50% dan TiO2 anatas tersupport AgI dan lama waktu penyinaran yaitu 15 menit, 30 menit, 45 menit, 60 menit, 75 menit, dan 90 menit. Untuk mengetahui pengaruh lama penyinaran terhadap fotodegradasi Remazol red, maka dilakukan pengukuran absorbansi larutan menggunakan spectronic 200 pada panjang gelombang 558nm setiap selang waktu 15 menit. Hasil aktivitas fotokatalitis menunjukkan persentase degradasi remazol red pada sistem TiO2 anatas tersupport AgI, TiO2 anatas 50%-rutil 50% dan tanpa katalis berturut-turut sebesar 32%, 16%, dan 7%. Oleh karena itu fotokatalis TiO2 anatas tersupport AgI memiliki aktivitas fotokatalisis yang lebih baik daripada fotokatalis TiO2 anatas 50% - rutil 50%

Abstract

General Chemistry I is a compulsory subject taken by preservice science teachers where concept mastery of the subject can be explored through an essay test. The purpose of this study was to describe the psychometric characteristics of the General Chemistry I essay test using the Andrich Rating Scale Model by the Winsteps program. The research was conducted in the Odd Semester of the 2022/2023 Academic Year involving 46 students who were selected through a cluster random sampling technique. Although the results of the psychometric analysis showed that the rating scale had not functioned as it should, the General Chemistry I essay test instrument proves to have good (unidimensional) construct validity with all items in the category of moderate difficulty level. This research at the same time proves that it is not easy to make and define categories in an essay test. The use of the Andrich Rating Scale Model provides very useful information for describing and improving the psychometric quality of essay tests on measuring the General Chemistry I ability of preservice science teachers.
