Abstract

This study aims to design a CUPs-SSI learning model that meets the criteria of valid, practical, and effective in improving students' understanding of chemical concepts. The resulting learning model is a cooperative learning model oriented to the application of social science issues in education. The type of research is R&D (research and development), with the design of the Plom development model. Data collection techniques use tests and non-tests. After going through the design, realization of design, and validation stages, the CUPs-SSI (conceptual understanding procedures oriented to socio scientific issues) learning model was produced which has six syntax or stages of learning, namely investigation, exploration, hypothesis, verification, presentation, and generalization. Other components of the CUPs-SSI learning model consist of social systems, reaction principles, support systems, instructional impacts, and herding impacts. The results of the limited trial of the conceptual understanding test of students after learning with the CUPs-SSI model, were in the good category with an average percentage of 85.11%. Thus, theoretically, this research shows that the CUPs-SSI model, can improve students conceptual understanding. Practically, the research results show that the CUPs-SSI model is suitable for use as an alternative learning model, especially for science material.

Abstract

Biosynthesis of silver nanoparticles (AgNP) is a process of changing Ag+ ions to Ag0. The biosynthesis method in this research is green synthesis using natural ingredients to reduce silver, this synthesis is safer, environmentally friendly and economical. Based on this, this research aims to determine the optimal reaction conditions in the biosynthesis process using ethanol extract from cock leaves. The research method carried out pH optimization with variations of 8, 9, and 10 and then obtained the best pH, where the pH optimization will later be used in the AgNO3 optimization process with variations of 1mM, 2mM, and 4mM. After obtaining the best Ag optimization, the next stage was extract optimization using variations of 0.5%, 1% and 2%, the results of which will be seen based on the SPR peak of 400-500 nm which indicates the formation of AgNPs. The results of the research showed that AgNPs from cockang leaf ethanol extract were able to reduce at pH 8, AgNO3 2mM and 4mM, as well as 0.5% extract, and the contact time reaction showed a good formula for AgNP 1, AgNP2, AgNP3 which was indicated by the absorbance intensity at long waves that form AgNPs at the SPR peak of 400-500. Based on the results of SEM characterization, the morphology at a concentration of 2 mM has a surface that is not very smooth and the size is not very uniform, but at a concentration of 4 mM the surface is smooth and the particles are not uniform. With particle sizes in the range of 50-80 nm.
