PENGEMBANGAN PENUNTUN PRAKTIKUM ADSORBSI ISOTERM MELALUI PEMANFAATAN LIMBAH KULIT PISANG SEBAGAI ADSORBEN PADA PRAKTIKUM KINETIKA KIMIA

Abstract

This research aimed to produce practical guiding products that are suitable for use and to know the students' responses to the products developed. Research & Development (R&D) was used as a form of research which was referred to the 4D model by Thiagarajan, but the implementation of the model just limited a 3D level. Subject tested the students of Chemistry Education FKIP Untan who had taken kinetics chemistry courses. Data collection tools used were validation sheets and student response questionnaires on the product developed. The results of the expert judgement obtained interpretation is very feasible in terms of aspects of content feasibility, presentation feasibility, linguistic feasibility, and graphic feasibility with consecutive total scores is 97%, 95%, 96%, and 96%. Students' responses to the results of small group trials were 81% with high interpretation and in large group, trials were 81% with very high interpretation.
