Penerapan Aplikasi ARBE Berbasis Inkuiri Pada Praktikum Larutan Penyangga Untuk Meningkatkan Kemampuan Reprsentasi Mahasiswa

Abstract

This study aims to describe student activities, analyze and analyze the increase in student representation abilities
after the application of guided inquiry-based ARBE applications in buffer solution practicum. The research method
used was a pre-experimental design with one group pretest-posttest. The subjects of thisstudy were second semester
students of the chemistry education study program at UIN Sunan Gunung Djati Bandung with a total of 33 students.
The instruments used were observation sheets of student activities, worksheets, and pretest posttest questions. The
resultsshowed thatstudent activitywas 91.8% with a very good interpretation. The increase in studentrepresentation
ability after implementing the guided inquiry-based ARBE application in the buffer solution practicum to improve
student representation ability was classified as high with a gain value of 0.72. Based on the t-test, a significance
value of 0.000 <0.05 means that H0 isrejected and Ha is accepted. This shows that the implementation of the guided
inquiry-based ARBE application in the buffer solution practicum was able to improve students' representation
abilities
