Abstract

This study aims to create a magazine and determine the level of validity and response of readers of science magazines regarding phytochemical tests of peluntan leaf extract (Artocarpus sericicarpus) as student reading material. This study is a research and development (RnD) with a 4D model (Define, Design, Development, and Dissemination). The validators for this science magazine are two lecturers of Chemistry Education. The research sample consisted of 30 students of the Chemistry Education Study Program who were selected using a purposive sampling technique and collected through a response questionnaire. Validation data were processed using the Aiken's V formula, while the magazine trial based on student responses was processed using the percentage formula. The validity results showed an average value of Aiken's V = 0.92, which is classified as very valid. The science magazine trial produced a value of 92.5%, which is classified as very useful. Based on these results, it can be concluded that the science magazine developed is very valid and useful for use as reading material. This research is expected to contribute to the development of useful reading materials in the field of Chemistry Education.

Abstract

This research aims to develop and measure the feasibility of a practicum module integrated with green ghemistry about complexion of cobalt with anthocyanin from dragon fruit’s peel extract as a supplementary learning material. This research employed a Research and Development (R&D) Method using 4D model (Define, Design, Develop, and Disseminate). The feasibility of the module is analyized from expert validity test using Aiken’s V formula. The validity test from 6 chemistry expertises show that the module has a very high validity score in all 4 aspects: content, alingment with green chemistry principles, presentation, and clarity of instruction, with V score 0.8867, 0.9425, 0.8875, and 0.8850 respectively. Therefore, the average V score for the module is 0,9004 (highly valid). So, it can be concluded that the module practicum is considered highly feasible to be used as a supplementary instructional material in the Transition Element Compound course
