Pengembangan E-Modul Pemisahan Senyawa Fenolik dari Fraksi Simpur Air dengan Teknik Kromatografi Lapis Tipis (KLT) Preparatif Sebagai Sumber Belajar Kimia Bahan Alam

Abstract

The purpose of this study was to determine the E-Module of Natural Materials Chemistry based on a flipbook application with the material for Separation of Phenolic Compounds from the Simpur Air (Dillenia suffruticosa) Fraction  using a preparative Thin Layer Chromatography (TLC) technique. The research method used is a research and development method by applying the ADDIE model. The subject of this research is the E-module for Separation of Phenolic Compounds from the Simpur Air (D. Suffruticosa) Fraction using Preparative Thin Layer Chromatography (TLC). The research instrument used was assessment and data analysis using a Likert scale. The data collection technique used is an indirect communication technique by giving a questionnaire. The feasibility of the E-module was assessed by two material experts, three media experts, and two linguists. The final results are seen in the material aspect which is obtained 100%, the media aspect is obtained 100%, and the language aspect is obtained 100%. Thus, it can be locked that the E-Module of Natural Materials Chemistry based on a flipbook application with the material for Separation of Phenolic Compounds from the Simpur Air (D. suffruticosa) Fraction Using a preparative Thin Layer Chromatography (TLC) technique is very feasible.
