Abstract

The study aims to determine the effect of applying the STEM approach using Google Classroom on student learning outcomes in acid-base learning. This research is quantitative experimental research with a quasi-experimental. The quasi-experimental design used in this study is a nonequivalent control group design. The sample in this study were students of class XI IPA SMA Al-Khairaat Kolono, 25 students of class XI IPA 1 and 22 students of class XI IPA 2. Data collection techniques used observation and giving tests consisting of pretest and posttest. The results of the learning activity data acquisition were the experimental class 80.4% and the control class 87.5%. This shows that the learning activities of students and teachers during the learning process are categorized as very high. The results of the student test analysis obtained a significance value from the t-test analysis of 0.002 <0.05 so it can be seen that H0 is rejected and Ha is accepted, which means that there is an effect of student learning outcomes on the application of the STEM approach to acid-base learning using Google Classroom.

Abstract

During the Covid-19 Pandemic, there has been a fundamental change in the implementation of chemistry learning. Face-to-face lectures and laboratory practice to accommodate the connectedness of the three levels of representation can no longer be carried out. Chemistry learning is fully replaced through online learning. The Chemistry MGMP in Palu City realizes the importance of making various efforts so that the chemistry learning process runs well in terms of delivering learning material and carrying out practicums in the laboratory. One application that can be used by combining various learning media that have been used by chemistry teachers (among others: the zoom application, WhatsApp, Google Class Room, LMS, etc.) is using Ice Cream Screen Recorder. There were 40 participants in the training who were chemistry teachers who were members of the Palu City High School Chemistry MGMP group. Activities carried out in the form of training and mentoring are carried out with a participatory model. Community service activities for the Palu City Chemistry Subject Teacher Consultation (MGMP) partners in the preparation of digital teaching materials during the Covid pandemic have been carried out well thanks to good cooperation with various parties. This is illustrated by the output in the form of ice cream-based digital teaching materials and flipbooks that the participants have made from the results of this community service training and mentoring. The final result of this service is according to the expected target, namely the existence of digital chemistry teaching materials that utilize the Ice Cream Recorder application used in chemistry learning.

Abstract

Conditions of the Covid-19 pandemic require teachers and students to innovate starting from the preparation, process, and assessment of learning. This study aims to design and determine the relevance and consistency of Lithium application learning media for high school students on chemical equilibrium in the form of e-modules as a solution to reduce misconceptions. This type of research is a part of Research and Development (R&D) starting from product design to determining its theoretical relevance and consistency by experts. The product produced is in the form of an e-module on chemical balance material using Android with the Lithium application which is used by students in online learning during the Covid-19 pandemic. The instrument used was a questionnaire on the feasibility of learning media, the suitability of the material, and the Lithium application. The results of the evaluation of the media expert validator and the material expert respectively obtained the value of relevance and consistency of 3.15 (valid); 3.00 (valid); and 3.65 (very valid). This means that the Lithium application can be used as an online learning medium by utilizing Android as a solution to reduce high school students' misconceptions of chemical equilibrium material.

Abstract

Kulit durian adalah limbah biomassa yang dapat dimanfaatkan sebagai bahan bakar alternatif menjadi briket arang. Kulit durian mengandung bahan yang mudah terbakar yaitu selulosa yang tinggi (50%-60%) dan lignin (5%) serta pati yang rendah (5%). Penelitian ini bertujuan untuk mengetahui karakteristik briket arang dari limbah kulit durian menggunakan perekat dari pati sagu sebagai bahan bakar alternatif. Perekat yang digunakan adalah perekat dari tepung sagu yaitu 3% dari berat arang yang digunakan. Dalam penelitian ini digunakan arang sebanyak 500 g, sehingga bahan perekat yang digunakan adalah 15 g. Hasil pengujian mutu produk briket berbahan baku kulit durian diperoleh nilai kalor (5189.128 kal/g), nilai kadar air (3,6044%), nilai kadar abu (3,5643%), nilai kadar zat menguap ( 21,1273%), dan nilai kadar karbon terikat (69,2279%), kerapatan (0,4778 g/cm3), laju pembakaran (0,22 g/sekon). Briket yang dihasilkan dari limbah kulit durian dengan menggunakan pati dari sagu sebagai perekat dapat dijadikan sebagai bahan bakar alternatif yang ramah lingkungan

Abstract

Understanding the concept is a process in which students are able to understand the information obtained, both the definition, nature and description of a concept so that they are able to construct the concept. Self Efficacy is the ability of individuals to organize the actions needed for certain achievements. This study aims to (1) describe students' conceptual understanding of atomic structure material and the periodic system of elements. (2) describe student self-efficacy in atomic structure material and the periodic system of elements. The type of research used in this study was descriptive research with a quantitative approach. The instruments used in this study were three-tier questions and self-efficacy questionnaires. This research was conducted at SMAN 4 Palu in class X MIPA students. The results showed that students' understanding of concepts in atomic structure material and the periodic system of elements averaged the percentage of students who understood the concept of 34.35% classified as understanding the concept of the low category, students who did not understand the concept of 24.1% were in the low category while students who experienced a misconception of 41.35% in the sufficient category. The results of student self-efficacy research show that student self-efficacy is good because most are in the high category of 45 students (75%), the sufficient category is 15 students (25%).
