This research was the development of chemistry teaching materials using Adobe Flash CS6 software which aimed to determine the feasibility level, readability level, and student response to chemistry teaching materials on the subject of colloid system. The development of this teaching materials used the ADDIE development model which was limited to the implementation stage. The research was conducted at MAN 1 Bengkulu City with the research subjects being 9 students of class XI IPA 2 for the teaching materials readability test and all students of class XI IPA 2 totaling 33 students for testing student responses to the teaching materials. From the results of the study, it was found that (1) the feasibility level of this teaching materials was 88.33% meanwhile the result from the media aspect was 87% therefore based on the validation results by the validator of the teaching materials developed using Adobe Flash CS6 software it was declared very valid, (2) based on the results of the teaching materials readability trial, the average percentage of teaching materials readability obtained was 84.04% with a very valid category, (3) based on the product trial, the average student response was 89.67% with a very valid category. Keywords: Teaching Materials, Adobe Flash CS6, Coloid System

This study is a research and development of ICARE-based chemistry e-modules that aims to determine the feasibility of e-modules, student responses, and improvement of student learning outcomes. The development model used is analysis, design, development, implementation, evaluation (ADDIE). The research was conducted at SMA Negeri 2 Seluma from January to August 2022. The subjects of this study were X IPA 2 and X IPA 3 students in the 2022/2023 school year who were selected based on simple random sampling techniques with a population of 3 classes, which were then tested for normality and homogeneity so that normal and homogeneous classes were obtained, namely X IPA 2 class for small group tests and X IPA 3 for large group tests. The instruments in this study were interview sheets, validation sheets, student response questionnaires, and tests. From the results obtained (1) ICARE-based chemistry e-modules were declared very feasible by media and material experts with a percentage of 98.88% media aspects and 91.25% material aspects, (2) Student responses to ICARE-based chemistry e-modules were in the very good category with an average percentage of 90.23%, and (3) After using ICARE-based chemistry e-modules on redox reaction material, there has been an increase in student learning outcomes as measured by an average N-gain score of 0.69 on moderate criteria. The results of the development of ICARE-based chemistry e-modules are very feasible to use in the learning process and proven to improve student learning outcomes.

A traditional plant, Ficus racemosa L., known as the ara plant in West Nusa Tenggara, is potentially beneficial as a drug candidate, which is one option to develop the biodiversity of natural ingredients in Indonesia. The extract was produced by maceration method with ethanol 96% solvent. Furthermore, they partitioned using various solvents, n-hexane, ethyl acetate, and chloroform. The presence or absence of secondary metabolite is determined by the phytochemical screening test. Meanwhile, the Brine Shrimp Lethality Test (BSLT) is a toxicity screening to determine the LC50 of extract and their partition with various concentrations used were 50, 100, 250, 500, and 1000 ppm. The metabolite secondary flavonoids, alkaloids, and saponins are confirmed. The analysis showed that LC50 of extract was 218,34 ppm; n-hexane fraction was 413,57 ppm; ethyl acetate fraction was 309.51 ppm; and chloroform fraction was 314.60 ppm; all had toxic potential.

Classroom Action Research (CAR) aims to improve learning outcomes and student engagement by utilizing the Problem-Based Learning (PBL) instructional model in Class X MIPA 1 at SMAN 9 in Bengkulu City. The CAR was conducted in May 2023 over 2 cycles. Each cycle comprises 1 session, spanning 3 instructional hours (3 x 45 minutes). The phases of each cycle commence with observations to diagnose issues, followed by design, implementation, event observation, evaluation, and reflection. Based on the results of the conducted data analysis, it was determined that the application of the PBL learning model was able to demonstrate an increase in learning outcomes and student engagement in Cycle 2. The average student learning outcomes improved from 77.66% to 59.38%, accompanied by an increase in the percentage of students achieving competency, from 85.47% to 81.25%. Student participation during the learning process also saw an increase in Cycle 2. Student engagement rose from 66.74% in the moderate category to 78.28% in the high category. Keywords: Learning outcomes, engagement, and PBL
