Abstract

Research This aims to develop practicum module for making soap with natural active ingredients to improve students' creative thinking skills. Practicum instructions will be applied to natural science and natural product chemistry practicum courses to provide innovations and appropriate technology for science education master students. The development of practicum instructions is a Research and Development (R & D) development with a define, design, develop, and disseminate (4D) model. The samples of this research were chemistry students and Master of Science Education students. The tests carried out were tests of physical properties (organoleptic, pH, and homogeneity) and antimicrobial tests with varying concentrations of trimyristin. Products in the form of practicum module are validated. The results showed that the validity value of the three validators obtained using the Aiken index was V = 0.84, which indicated that the natural science practicum module: the procedure for making trimyristin soap from nutmeg, was very valid and feasible to use. Meanwhile, practicality can be seen from the responses of students and lecturers, who show a positive response with average practicality of all components of 88% of student responses and 89% of lecturer responses. The results of the physical evaluation of trimyristin solid soap (organoleptic, pH, foam stability, and moisture content) produced from this study showed good results because they met several standards for the quality of solid soap SNI 3532-2016. Based on these data, the materials chemistry practicum module: procedures for making trimyristin soap from nutmeg seeds to support meaningful learning that is developed is very valid and very practical to use in the learning process

Abstract

Learning tools have been developed through lesson plans, worksheets based on learning-guided discovery, and assessment instruments to improve critical thinking skills on the sub-subject factors that affect the reaction rate. The stages carried out in the production process of the two types of learning devices are defining, planning, and development, which are the three stages of the four stages of the 4D model. Two lecturers and one teacher validate the quality of the developed learning tools. Based on the results of data analysis, the lesson plan as a whole has good quality, the student worksheet is in the very good category, and the instrument for assessing students' chemical critical thinking skills has a high category of validity. Based on the integration of learning model guided discovery, the lesson plan and student worksheet have very good quality, and the integration of critical thinking skills in the assessment instrument is very good.
