Media memiliki peran penting dalam membantu peserta didik mencapai hasil dan tujuan pembelajaran secara optimal. Pada penelitian ini dilakukan pengembangan media pembelajaran yang mengintegrasikan bahan-bahan yang terdapat di sekitar siswa untuk memudahkan siswa dalam mempelajari materi termokimia. Kelayakan media yang dikembangkan dievaluasi melalui penilaian materi, media, dan respon pengguna. Keefektifan media pembelajaran diukur melalui pencapaian ketuntasan belajar siswa terhadap nilai Kriteria Ketuntasan Minimal (KKM). Pada penelitian dan pengembangan ini digunakan model ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Validasi media oleh guru sejawat menunjukkan bahwa media pembelajaran termokimia berbahan dasar material lokal yang dikembangkan sesuai dengan tuntutan materi dan telah memenuhi kriteria menarik, praktis, dan sangat layak digunakan sebagai media pembelajaran termokimia. Hampir seluruh siswa memberikan tanggapan positif terhadap media yang dikembangkan dan menilai bahwa media termokimia berbahan dasar material local dapat membantu pengembangan aspek bekerjasama dan berkomunikasi siswa. Penilaian terhadap ulangan harian siswa selama tiga tahun menunjukkan bahwa hampir sebagian besar siswa memperoleh nilai yang lebih tinggi dibandingkan nilai KKM, yang mengindikasikan bahwa media yang digunakan efektif dalam membantu pencapaian ketuntasan belajar siswa. Media yang dikembangkan menyediakan alternatif inovasi pembelajaran yang mampu membantu pencapaian ketuntasan belajar siswa.

The COVID-19 pandemic is a new situation that brings challenges to all sectors, including education. One of the impacts is that there is an adjustment in the implementation of learning, including practicums, which are usually held offline, turning into online learning. In this study, an analysis of the implementation of biochemistry practicum was carried out for two semesters during the Covid-19 pandemic. This study uses a descriptive case study design. Research data obtained from document analysis and questionnaires. There are five classes used as samples of this study. Questionnaires were given to 116 students. The results showed that the implementation of the biochemistry practicum had been carried out well. This is marked by positive responses from students through questionnaires. Even so, there are significant differences in student achievement compared to conditions after the pandemic. This shows that practicum activities, especially those related to laboratory skills, cannot be facilitated with online learning

This study addresses the limited integration of Discovery Learning, a Hess’s Law Enthalpy Change Determination Simulator, and student worksheets (LKM). These components have generally been implemented separately or in different combinations in previous studies, and simulation-based learning in Hess’s Law remains limited. The study aimed to examine students’ conceptual understanding of Hess’s Law, both overall and across specific learning objectives, after implementing the Discovery Learning model integrated with a Hess’s Law Enthalpy Change Determination Simulator and student worksheets. The research employed a pre-experimental one-group pretest–posttest design involving 29 senior high school students. Data from the conceptual understanding test were analyzed using descriptive and inferential statistics. The paired-sample t-test revealed a statistically significant improvement from 35.06 to 63.22 (t= −8.11, p < 0.001). At the level of specific learning objectives, the Wilcoxon signed-rank test showed that students achieved greater gains in inferring Hess’s Law from comparisons of reaction pathways than in determining enthalpy change based on Hess’s Law. These findings indicate that the instructional approach was associated with improved conceptual understanding of Hess’s Law. This study suggests that integrating Discovery Learning with a Hess’s Law Enthalpy Change Determination Simulator and structured worksheets may support students’ conceptual understanding of Hess’s Law and serve as a practical instructional strategy in chemistry education.

Pembelajaran teori asam basa memerlukan media yang mampu memvisualisasikan konsep abstrak dan meningkatkan keterlibatan peserta didik. Penelitian ini bertujuan melakukan pengembangan lanjutan media pembelajaran interaktif berbasis website pada submateri teori asam basa melalui penyelarasan aktivitas dalam media dengan tahapan Predict-Observe-Explain (POE), perangkat pembelajaran, serta fitur media. Metode penelitian yang digunakan adalah development research dengan mengadaptasi model pengembangan ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Data diperoleh melalui lembar validasi ahli serta angket tanggapan pendidik dan peserta didik yang dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa pengembangan lanjutan dilakukan dengan mengubah platform media dari aplikasi berbasis smartphone (Android) menjadi berbasis website, mengintegrasikan sintaks Predict-Observe-Explain (POE) melalui penambahan aktivitas Predict berbasis video pada materi teori Arrhenius, serta menyempurnakan navigasi dan beberapa fitur media. Hasil validasi ahli menunjukkan bahwa media memperoleh persentase kelayakan sebesar 83,75% dengan kategori sangat layak, kemudian disempurnakan berdasarkan masukan validator sebelum dilakukan uji coba terbatas. Selanjutnya hasil uji coba terbatas menunjukkan bahwa media memperoleh persentase tanggapan sebesar 100% dari pendidik dan 97,03% dari peserta didik yang keduanya termasuk dalam kategori sangat baik. Dengan demikian, media pembelajaran interaktif berbasis website hasil pengembangan lanjutan layak digunakan sebagai alternatif media pembelajaran pada submateri teori asam basa.

In determining the reaction rate between hydrochloric acid (HCl) and sodium thiosulfate (Na₂S₂O₃), conventional experiments commonly rely on visual observation of sulfur turbidity, making endpoint determination highly dependent on lighting conditions and observer judgment. These limitations reduce measurement accuracy, repeatability, and objectivity, highlighting the need for an alternative Data Acquisition System (DAS) capable of providing continuous quantitative measurements. This study focuses on the development and optimization of a Data Acquisition System (DAS) utilizing transducers and photodetectors through the Research Science Design (RSD) approach as an alternative method for reaction kinetics analysis. The experimental setup consisted of a borosilicate reactor enclosed in a black acrylic chamber to minimize ambient light interference, equipped with 3 W high-power LEDs (green, blue, and white) as light sources and a Mini Mixer interface integrated with MGA software for continuous data acquisition. Each LED configuration was evaluated through three experimental repetitions, and the recorded signals were analyzed using Relative Standard Deviation (RSD) to assess measurement stability and determine the optimum light source. Based on the evaluation results, the DAS was capable of (1) continuously recording sulfur colloid formation in real time, (2) demonstrating the highest measurement stability under green light with an RSD of 1.18%, and (3) eliminating observer-dependent visual bias. The proposed system provides a simple, coding-free, objective, and affordable solution for improving the quality and efficiency of reaction kinetics measurements in chemistry education.
