Abstract

This research is a descriptive study that generally aims to analyze the results of chemistry learning in the acid-base subject of class XI 4 students at SMKN 4 Pontianak in terms of their learning styles. Students at SMKN 4 Pontianak have varied learning outcomes and different learning methods and styles. Learning styles are very important to know for both teachers and students of class XI APL SMKN 4 Pontianak. With knowledge of learning styles, we can identify and use learning methods that best suit each student's learning preferences. This can result in a better and more effective understanding of the material, as well as increasing satisfaction in the learning process. The instruments for this research are a learning style questionnaire, interview guide. Based on the results of data analysis, information was obtained that the tendency for student learning styles to be dominated by the kinesthetic learning style for unimodal learning styles was 56.25% and the K-V learning style for multimodal learning styles was 18.75%. The students' learning outcomes on the acid-base material taught by the teacher show the following daily average scores: acid-base titration 70.3, Mohr titration 73.9, and redox titration 76.4.

Abstract

The learning of chemistry requires practical activities to assist students in understanding chemical concepts deeply and also to connect scientific principles with everyday life. However, practical activities often face challenges such as inadequate equipment and materials in laboratories, posing a challenge for educators to conduct practical-based learning. This article proposes the development of natural pH indicators based on bacterial cellulose to enhance acid-base learning in schools. These natural pH indicators are formulated by combining plant-based natural indicators with (Biocellulose) and immersing them in buffer solutions ranging from pH 1 to 14. The color changes produced by these natural pH indicators based on bacterial cellulose indicate different pH levels, serving as a reference for each solution measurement.These indicators are used in classroom learning during acid-base topics in the 11th-grade science classes. Stimulates curiosity and interest among teachers and students, leading to more engaged observations during the experiments.Overall, teachers and students perceive these natural pH indicators based on bacterial cellulose as effective tools for conveying acid-base concepts and enhancing engagement in practical-based learning methods.
