Abstract

The low problem-solving ability of chemistry students in solving contextual problems is related to their low conceptual understanding and environmental literacy. Based on these problems, this study aims to improve problem-solving abilities and conceptual understanding through the development of a biodiesel e-module with a valid, practical, and effective STEAM Web Based Blended Learning (STEAM WBBL) approach. This study uses the ADDIE model for research and development. This study was conducted on 40 Chemistry Education students of the Faculty of Teacher Training and Education. Data collection techniques used questionnaires and test instruments for problem-solving abilities, conceptual understanding, and environmental literacy. The effectiveness analysis technique used a written test in the form of problem-solving ability and conceptual understanding test instruments. Based on the validity test, the developed biodiesel e-module was declared valid, very practical, and effective in improving students' problem-solving abilities, conceptual understanding, and environmental literacy with N-gain values of 0.75, 0.73, and 0.68, respectively. The biodiesel e-module application with the STEAM WBBL approach is suitable for use as a teaching material.

Abstract

The present study by investigating an alternative approach integrating natural materials to create more contextual and meaningful learning experiences. A quasi-experimental design was employed, with the experimental group engaging in hands-on laboratory projects using natural indicators such as purple cabbage extract, eggshell waste, and vinegar, while the control group received conventional instruction. Independent t-test analysis revealed a significant difference between the groups, with the experimental group outperforming the control group in post-test assessments of scientific literacy and critical thinking. These findings indicate that incorporating environmentally friendly, context-based materials into chemistry education could effectively enhance essential skills. Moreover, the project-based approach encouraged students to apply scientific concepts, think critically, and relate their learning directly to everyday life.

Abstract

The study aimed at finding out in dept about the interaction between Problem Posing model assisted with Autograph Software with the student’s gender to students' mathematical communication ability. This study used quantitative research with quasi experimental method. The approach used was a scientific one. The population of this study were all the Class X students of MAN Kisaran. The sample in this study were the students of class X-IPA1 and X-IPA-2 in MAN Kisaran of Asahan Regency. This study was conducted in the even semester of the academic year 2017/2018. Data analysis was done by 2-way ANOVA test. Based on the statistical calculation, it can be concluded that the value of Fcount<Ftable is 0.778 <3.12. This shows that Fcount<Ftable(0.778 <3.12) is not significant so that it can be concluded that H0 is accepted and Ha is rejected which means there is no interaction between learning with students’ gender. The finding of students’ actitivity aspects is based on direct observation. Female students are more active in learning but are weaker in reasoning, meanwhile Male ones are quick in reasoning but are less active in learning.

Abstract

Kegiatan pengabdian ini dilatarbelakangi oleh pentingnya mengoptimalkan pembelajaran menggunakan teknologi di Era Revolusi Industri 4.0 dan Society 5.0 yang mengharuskan pembelajaran berkonversi dari manual menuju digital. Tantangan guru menghadapi keterbatasan situasi pandemi Covid-19 untuk berlatih pembelajaran secara daring. Pengembangan Learning Management System (LMS) berbasis website bertujuan untuk membantu guru-guru dalam metode pengajaran, kepraktisan berdasarkan angket respon peserta didik serta keefektifan modul berdasarkan ketuntasan belajar peserta didik. Penelitian ini menggunakan desain berdasarkan  hasil  observasi  pada  tenaga  pengajar  di  SMK Ma’arif NU 1 Cilongok  dapat  diketahui  bahwa guru masih belum dapat membangun pembelajaran dengan memanfaatkan teknologi yang ada yaitu komputer dan internet. Sehingga hasil pembelajaran dirasa kurang maksimal. Oleh karena itu, perlu kiranya dikembangkan Tutorial Edmodo untuk Tenaga Pengajar yang berisi tutorial penggunaan dan pemanfaatan Edmodo dalam pembelajaran agar dapat digunakan tenaga pengajar untuk untuk memecahkan masalah tersebut.

Abstract

Antioksidan merupakan senyawa yang mampu menghambat laju oksidasi dalamtubuh. Antioksidan sintetik dapat menimbulkan efek samping pada kesehatantubuh sehingga penggunaan antioksidan alami sebagai pengganti semakindiminati masyarakat karena dipercaya lebih aman. Salah satu golongan senyawaalami yang bersifat sebagai antioksidan adalah golongan fenolik. Daun kopi kawamengandung flavonoid, alkaloid, saponin, kafein, dan polifenol. Penelitian inibertujuan untuk mengetahui kadar fenol total dan harga Effective Scavenging(ES)50 ekstrak etanol daun kopi kawa. Daun kopi kawa diekstraksi menggunakanmetode maserasi. Ekstrak kental diuji kandungan fenoliknya dengan reagen Folin-Ciocalteu dan standar asam galat. Hasil uji kandungan fenolik total dinyatakandengan kesetaraan asam galat per gram ekstrak (GAE/g ekstrak). Hasil penelitianmenunjukkan ekstrak etanol daun kopi kawa memiliki kandungan senyawafenolik total sebesar 55,87 mg GAE/g ekstrak. Ekstrak etanol daun kopi kawamemiliki aktivitas antioksidan dengan nilai ES50 sebesar 57,79 μg/mL sedangkanuntuk standar asam galat memiliki nilai ES50 sebesar 1,54 μg/mL. Hasil tersebutmenunjukkan ekstrak etanol daun kopi kawa memiliki aktivitas yang kuat sebagaiantioksidan.

Abstract

Critical thinking skills and knowledge learning outcomes are very important for students in today's chemistry learning. However, the results of the PISA test, preliminary studies, and previous research indicate that both aspects still need to be improved. This study uses an R & D approach utilizing the ADDIE model to create a chemical bond e-magazine based on the SCT model that is valid, practical, and effective in enhancing critical thinking skills and knowledge learning outcomes. This study involved five expert validators and 66 grade XI students of SMA Negeri 8 Banjarmasin. The data were gathered through questionnaires, observation sheets, and tests, and then analyzed descriptively. The findings revealed that (1) the e-magazine produced demonstrated a high level of validity (90%) in terms of content, presentation, language, and media, (2) practical with an average score of 88%, and (3) effective with an N-Gain of 0.71 (critical thinking) and 0.75 (knowledge) categorized as high, with an average achievement score of 83%.

Abstract

Craftsmen in Madara Sasirangan lack skills in producing and marketing natural Sasirangan products. To address this, training on natural color Sasirangan technology will be provided in Sasirangan Village, enhancing their production and marketing knowledge and skills. The method used is four stages, namely the 1) Socialization, 2) Training, 3) Monitoring and Evaluation, and 4) Program Continuation stages. Community service was attended by 15 participants/craftsmen for eight meetings from October to November 2025. Lectures and discussions on natural dye extraction techniques, Sasirangan production, and marketing media were held in three meetings. Demonstrations/practices of making natural color Sasirangan from plants were held in three meetings. Furthermore, monitoring and evaluation were held in two meetings. The evaluation results are that (1) There are various types of colors produced from natural dye sources. The suitability between pigment compounds and materials, extraction processes, mordanting, and dyeing can produce good coloring. (2) Participants have an understanding and skills in making Sasirangan natural dyes and marketing them of 80% (good category). Training enhances participants' empowerment in natural Sasirangan product production and marketing, with a focus on natural dye extraction, biomordants for durability, consumer education, and support for sustainable businesses.
