Abstract

This study aims to show an increase in students’ chemical representation ability through the integration of Problem-Based Learning (PBL) assisted by Nearpod on electrolysis cell material and describe student activities and their ability to complete worksheets. This study used a pre-experimental method with a one group pretest-posttest design and involved second-semester students in the basic Chemistry 2 courses. The results showed that the improvement in chemical representation ability was in the medium category (N-Gain: 0.68), learning activities were carried out very good (88.86%), and the student’s ability to complete worksheets was also classified as high (average score: 89.52). These findings indicate that integrating PBL assisted by Nearpod is an effective, innovative approach to improving students’ chemical representation ability, particularly in abstract electrolysis cell material, by encouraging active participation and conceptual understanding.

Abstract

This study aims to describe the application of guided inquiry-based worksheets, describe students' scientific performance in learning, and analyze the effectiveness of using bagasse adsorbents in reducing Fe levels. The method used is a pre-experiment with the One Shoot Case Study design. The research subjects were students majoring in Chemistry Education at UIN Sunan Gunung Djati Bandung in the Separation Chemistry course with 15 students. The instruments used are worksheets and student scientific performance observation sheets. The ability of students to complete worksheets based on data obtained an average score of 92.5 in the very good category. While the scientific performance of students gets an average score of 89 in the very good category. Using sugarcane bagasse adsorbents in drilled wellwater samples also decreased Fe levels in samples taken from drilled well water at Al Ihsan Islamic boarding school by 34.2% and on campus II samples by 28.1%. This shows that the application of the worksheets on the use of bagasse waste as an Fe adsorbent can measure student scientific performance.
