Abstract

Teaching materials play an essential role in education, serving as critical resources and guides for both teachers and students. They significantly enhance students' understanding and competency development by aligning with curriculum demands, particularly skill-based competencies. Science process skills are vital for engaging students in Physics, yet traditional teaching methods often limit the development of these skills. Effective Physics education should incorporate diverse strategies, including the case study approach, which fosters scientific thinking, creativity, and problem-solving skills. Implementing a scientific approach can further enhance these skills but may present challenges such as reduced learning pace and student interest. Teachers must address these challenges through close monitoring and thorough preparation, ensuring teaching materials are valid and effective. Researchers propose integrating case-based methods with a scientific approach to aid students in learning wave phenomena, making Physics concepts more accessible. The effectiveness of these materials will be evaluated using the N-Gain test, a statistical measure assessing improvement in student performance through a quasi-experimental pretest-posttest design, with data analyzed using SPSS. This study aims to identify issues and gather user feedback to optimize Physics teaching materials. The analysis of teaching materials developed using the case method, supported by a scientific approach, reveals their effectiveness in enhancing students' science process skills. The average N-Gain score of 0.71, reflects a 71% improvement, these materials significantly improve students' abilities, particularly in the Sound Wave subject. The effectiveness is evident in the enhanced skills of analysis and problem-solving among students, validated through pre-test and post-test comparisons. The average pre-test score was 60.4, which increased to 88.3 in the post-test. Despite some challenges such as inconsistent internet access, the teaching materials proved to be highly effective, with 20 students achieving effective results and 10 achieving fairly effective results. The teaching materials also foster various science process skills including critical thinking, experimentation, and communication. These methods encourage student engagement, critical thinking, collaboration, real-world application, creativity, and overcoming learning barriers, making education more dynamic and interactive.

Abstract

This study aims to analyze the differences in Indonesian spelling errors among students based on their regional dialects at Al Razi Sinar Harapan  Junior High School. The research method employed is a combination of qualitative and quantitative approaches involving interviews with Indonesian language teachers and questionnaires distributed to students. The findings indicate variations in spelling errors among students from different regions, as well as the influence of regional dialects on spelling error patterns. Additionally, the impact of social media and technology contributes to students' spelling errors. This research provides a deeper understanding of the factors affecting Indonesian spelling errors among students.

Abstract

Penelitian ini membahas pentingnya penerapan hukum pembuktian dalam yurisdiksi militer, khususnya pada kasus pembunuhan yang dilakukan oleh 10 prajurit TNI AD (Batalyon Infanteri) kepada seorang warga sipil di Denpasar, Bali. Kasus ini telah terdaftar dalam Pengadilan Militer Nomor : 29-K/PM.III-14/AD/IX/2025. Pemicu permasalahan ini berawal ketika korban menyalahgunakan kepercayaan temannya yang termasuk salah satu prajurit tersebut. Tujuan penelitian ini berfokus pada proses pembuktian, penggunaan alat bukti, sampai pertimbangan hakim yang didasari atas kekuatan alat bukti yang dipakai. Kemudian, penelitian ini menggunakan metode penelitian hukum normatif dengan pendekatan kasus (case approach) serta didasari dengan perundang-undangan (statute apporach). Hasil penelitian ini ingin menunjukan bahwa Oditur Militer sebagai pihak penuntut (actori in cumbit probatio) berhasil membuktikan unsur-unsur tindak pidana berdasarkan minimal dua alat bukti yang sah yaitu dengan Visum Et Repertum (VER) dan alat bukti berupa alat penyiksaan sampai komunikasi digital. Namun, terdapat tantangan signifikan dalam pembuktian unsur penyertaan (deelneming) terhadap 10 pelaku secara kolektif. Secara yuridis, penerapan asas negatief wettelijk bewijs telah dipenuhi. Namun, temuan ini menggarisbawahi perlunya tinjauan ulang terhadap konsistensi pertimbangan hakim dalam menjamin rasa keadilan bagi korban sipil yang diadili di lingkungan militer. Disimpulkan bahwa akuntabilitas peradilan militer dalam menangani kasus tindak pidana umum membutuhkan harmonisasi hukum acara untuk memperkuat perlindungan hukum bagi warga sipil.
