Abstract

This study aims to determine the effect of students' understanding of the concept after usinge-handout based on POE on students' harmonic vibration material. This type of research is a quantitative study using pre-experimental methodsone group pretest-posttest design. The research instrument was a concept understanding test consisting of 12 questions. The data obtained from the analysis of understanding the concept gets an averagepretest of 32.333 and posttest of 79.933. The results of the analysis wit hpaired samples t-test ie tcount < ttablenamely 0.000 <0.05. So it can be concluded that there is an effect after using the POE-based e-handout on students' understanding of concepts.

Abstract

Understanding physics concepts often faces difficulties due to the lack of resources that can encourage students in learning and improve their understanding. One solution is to use Proteus software as physics learning media. The purpose of this meta-analysis is to evaluate the effect of using Proteus software media in physics learning. This meta-analysis research method involves several stages, such as formulating the research problem, collecting data from various studies, coding the data, and analyzing and interpreting the data. In the journal search, 36 articles were found that discussed the application of Proteus software media in physics learning. There are 6 articles that are relevant to the research conducted. In this article shows that there is a strong influence of the application of proteus software media in learning physics. in this study revealed that the results of the calculation of the effect size of the application of proteus software media in learning physics is 1.55 which is classified as high at 94%. This shows that proteus software media has a high influence in learning physics, especially at the SMA / SMK / MA education level.

Abstract

This research was motivated by students' low understanding of alternating current concepts, with 68% of students experiencing difficulties and an average daily test score of only 65, below the minimum completion criteria of 75. The study aimed to develop and test the validity of a vertical axis windmill learning media in enhancing students' understanding of alternating current concepts at MA Darul Ulum Palangka Raya. The Research and Development (R&D) method with a 4D model (Define, Design, Develop, Disseminate) was used in media development, with validation conducted by media experts using assessment instruments for appearance and attractiveness aspects. Data analysis employed percentage techniques to determine media feasibility levels. Results showed satisfactory validity levels, with appearance aspects reaching 87.5% (highly valid) and attractiveness aspects at 75.0% (valid). This learning media proved suitable for physics education, featuring the ability to demonstrate alternating current generation principles practically and interactively through a vertical axis windmill system equipped with mini generators and digital oscilloscopes.

Abstract

Keselamatan dan Kesehatan Kerja (K3) laboratorium memegang peranan penting terhadap pembelajaran sains yang belum dipahami secara optimal oleh siswa pendidikan menengah. Kegiatan pengabdian ini bertujuan memberikan pengenalan K3 laboratorium kepada siswa kelas X MAN Kota Palangka Raya melalui penyuluhan dan pembuatan poster edukatif. Kegiatan dilaksanakan sebagai bagian dari program MBKM Asistensi Mengajar dengan metode Service Learning yang melibatkan 34 siswa kelas X-B dalam enam kelompok kerja. Tahapan kegiatan meliputi observasi awal, penyuluhan dan diskusi interaktif, pembuatan poster edukatif dengan topik prosedur keselamatan, penerapan alat pelindung diri, tata cara penanganan zat kimia berbahaya, dan simbol-simbol keselamatan, presentasi dan evaluasi, serta praktikum laboratorium. Kegiatan yang dilakukan menghasilkan peningkatan signifikan pada aspek pengetahuan dan kesadaran siswa terkait keselamatan kerja di laboratorium. Siswa berhasil menghasilkan enam poster edukatif berkualitas baik yang mencakup aspek pemahaman konsep, kreativitas, relevansi, kualitas tampilan, serta kemampuan komunikasi. Observasi praktikum menunjukkan kesadaran keselamatan kerja telah terinternalisasi dalam diri siswa, terlihat dari kepatuhan menggunakan APD dan kehati-hatian dalam bekerja. Kegiatan ini berhasil memberikan pemahaman komprehensif tentang K3 laboratorium dan menghasilkan media pembelajaran berkelanjutan berupa poster edukatif untuk sivitas akademika madrasah.
