Research on the application of the ICARE learning model to the redox reaction material in class X was done. The purpose of the study was to determine the activities and responses of students to the ICARE model. This study uses a quantitative approach. This type of research was a quasi-experiment. The research subjects were 25 students of class X MIA 1. The instruments used in the study were the students' activity observation sheets and questionnaire responses sheets. The results of observations of the activities of experimental class students at the first meeting were 83.65% and 92.19% at the second meeting. Students' responses to the application of the ICARE model on the redox reaction material were said to be very amenable to the percentage of 85.20%. Thus it can be concluded that the application of the ICARE model can increase activities and respond very well by students in the learning process so that this model can be used in the learning process on redox reaction materials.

This research aimed at developing e-poster as learning media, analyzing how students respond to the e-posters uploaded to Instagram. This R&D research utilized an ADDIE model of development consisting of five stages: analysis, design, development, implementation, and evaluation. The research took place during even semester at the Department of Chemical Education, Faculty of Education and Teacher Training, Universitas Syiah Kuala. A total of twenty-four students (4 male and 20 female) who enrolled in the course of "elements and compounds of primary groups" voluntarily took part in the research subjects. We collect the data using the following instruments: A validity assessment form, a questionnaire for students, and an active Instagram account necessary for uploading the contents and monitoring students' activity on the platform. The results show that the validity score of e-posters was 97.5%, and 89 % of students responded positively to the media, and the vast majority of students would prefer to learn using e-posters in the future. The findings indicated that e-posters could contribute as alternative learning media to help students understand the concept of alkali group elements

This study explored a simple preparation and characterization of the activated carbon and cloth from the palm kernel shell and compared it to the commercial-water-filter-carbon specification. A new pyrolysis chamber that is easily scaled up using the palm kernel shell itself as a heat source was tested. Two different steps were compared: the alkaline activation process performed before or after the carbonation process in the palm-kernel-shell carbon preparation. The palm-kernel-shell activated carbons prepared with the current method fulfilled the standard quality of activated charcoal except for the ash content. The sequencing step of the preparation affected the adsorption capacity. Instead of the reverse sequence, the soaking palm kernel shells in NaOH before the carbonation process lead to a higher adsorption capacity. The carbon particle stability on the cloth surface was affected by both the adhesive concentration and its size. The ammonia adsorption capacity of activated carbon cloth (ACC) was between 1–4 mg ammonia per g stuck carbon. The preparation and the carbon type source on ACC affected the adsorption capacity. The ACC absorbed and lessened the skim latex odor vapor, nearly odorless depending on the ACC area and the volume of odor vapor.

The development of more sophisticated technology has become a powerful tool for achieving more effective and efficient educational objectives. In this instance, learning media that employ social media has been extensively adopted, and one of the potential alternatives is to utilize social media as learning media. This study aims to develop an e-poster social media Instagram on the material factors that affect corrosion and see the response of Chemical Education students of FKIP USK to the developed media. Using the ADDIE approach, RD (Research and Development) is the sort of research used. Student requirements surveys, an evaluation of the viability of the e-poster medium, and student response questionnaires were used to gather data. This research was carried out on the campus of the Faculty of Teacher Training and Education, Syiah Kuala University, Department of Chemistry Education, with research subjects being students majoring in Chemistry Education Force 2020 FKIP Syiah Kuala University consists of 3 class units with a total of 61 students consisting of 57 female and four male. The results showed that With an average percentage of 89 percent, the generated e-poster learning material meets the requirements for "very viable." With an average score of 84 percent, student reactions to the generated medium met the criterion for "extremely feasible." Based on the study's findings, the e-poster is a viable alternative learning medium.Keywords: Development; Learning Media; Instagram; E-Poster; Corrosion
