Abstract

This study aims to improve students' ability to master physics concepts on sound waves material in terms of students' learning styles through the Problem-Based Learning (PBL) model. The learning styles that are the focus of this study consist of visual, auditory, and kinesthetic. This research is pseudo-experimental research with a quantitative approach. One Group Pre-test Post-test Design is a research design used to apply the PBL model to determine the extent of improvement in mastery of the sound wave concept based on the learning style of students. The population in this study were students of class XI IPA SMA Negeri 42 Central Maluku, with a sample size of 24 people. The instrument used to analyze the learning style of students consists of test questions, questionnaires, and Learner Worksheets (LKPD). Based on the analysis carried out, it can be seen that before the application of the PBL model, overall students were failing qualifications with the average Pre-test obtained by students being 12.34. Based on these results, the number of students whose learning styles are classified as visual is 9 people (38%), auditory is 7 people (29%), and kinesthetic is 8 people (33%). After applying the PBL model by taking into account the learning styles of students during the teaching and learning process, the average LKPD achievement score in the visual group was 87.78, auditory was 85.71, and kinesthetic was 88.50, and was in good qualification. These results were then further reviewed through the Post-test, with an average achievement score of 80.48 with good qualifications. Based on these results, the N-Gain test was then carried out and the average score achieved was 0.8 with high qualifications. Thus it can be concluded that the PBL model can improve students' mastery of concepts on sound wave material based on students' learning styles.

Abstract

Kurikulum Merdeka Belajar adalah salah satu inovasi penting dalam pendidikan Indonesia yang memberikan kebebasan kepada pendidik untuk memilih perangkat ajar dan memanfaatkan teknologi dalam pembelajaran. Pelaksanaan pengabdian kepada masyarakat ini bertujuan untuk membantu pendidik menggunakan media teknologi dalam model pembelajaran sehingga dapat diimplementasikan secara maksimal pada era kurikulum merdeka belajar. Objek kegiatan ini adalah semua pendidik SMA/SMK mata pelajaran matematika di Kecamatan Kairatu, Seram Bagian Barat. Kegiatan PkM dilakukan dalam bentuk pelatihan kepada 28 peserta yang merupakan pendidik dengan diberikan kuisioner awal (pretest) dan akhir (posttest) untuk dianalisis tingkat pemahaman materi yang diberikan. Hasil penelitian menunjukkan bahwa pelatihan ini efektif dalam meningkatkan pemahaman pendidik tentang pemanfaatan media teknologi dalam pembelajaran. Hal ini dibuktikan dengan hasil uji N-gain yang menunjukkan peningkatan pemahaman peserta pelatihan. Namun, pelaksanaan kegiatan ini memerlukan peningkatan, terutama dalam hal durasi kegiatan dan ketersediaan fasilitas laboratorium komputer untuk praktik langsung.

Abstract

Penelitian ini bertujuan untuk memperoleh rekomendasi perbaikan dan membuat desain aplikasi media pembelajaran berbasis desktop dalam bentuk prototype untuk mata kuliah Statistika Dasar. Untuk memperoleh rekomendasi tersebut, maka dalam penelitian ini menerapkan metode usability testing dengan target pengujian yaitu kelompok dosen dan mahasiswa sebanyak 30 responden dengan tujuan untuk memperoleh 97% permasalahan dalam usability testing. Data yang dikumpulkan untuk memperoleh rekomendasi perbaikan dengan menggunakan metode usability testing, meliputi data-data yang bersifat kualitatif. Adapun pembuatan prototype dalam penelitian ini menggunakan prinsip desain interaksi. Berdasarkan hasil penelitian yang dilakukan, diperoleh beberapa rekomendasi yaitu terkait dengan desain pada tampilan interface dan konten yang terdapat pada halaman Menu Utama (Beranda), halaman Menu Game Education, dan halaman Menu Materi, di mana perlu dirancang kembali agar lebih memudahkan user dan tidak menimbulkan kejenuhan selama menggunakan aplikasi tersebut.

Abstract

This study develops a decision support system to recommend microcontroller and IoT learning devices for schools, universities, and training centers under realistic budget constraints while considering both technical capability and educational suitability. The alternatives are grouped into three budget tiers and evaluated using nine criteria covering price, CPU frequency, Flash, RAM/PSRAM, connectivity, usable GPIO, ease of learning, learning resources/community, and local availability/warranty. Objective criterion weights are computed using the Entropy method, and tier-wise rankings are produced using Additive Ratio Assessment (ARAS) through utility scores relative to an ideal alternative. Indicative local price and availability information are compiled from Tokopedia, while qualitative criteria are scored using consistent rubrics to support reproducibility. The results identify ESP32-CAM + baseboard as the top recommendation in Tier 1, LILYGO T-Display S3 in Tier 2, and M5StickC Plus2 in Tier 3; across tiers, Entropy assigns the largest weights to the most discriminative criteria, particularly RAM/PSRAM and, in higher tiers, Flash. The study is limited by market price volatility, approximations in usable GPIO values, and rubric-based qualitative scoring, and it also reflects the tendency of Entropy to concentrate weights on highly dispersed criteria, potentially amplifying outlier advantages. Overall, the proposed tier-aware Entropy–ARAS framework provides a transparent and actionable approach for educational institutions to justify device procurement and usage decisions based on budget, functionality, and learning readiness.

Abstract

This study proposes a decision-support approach for selecting prepaid mobile data packages in Ambon City that balances price, main quota, and validity period. Twelve packages from Telkomsel, XL, Indosat IM3, and Tri were evaluated using four criteria: price, main quota, validity, and price per main gigabyte. TOPSIS was used for ranking, and Entropy and CRITIC were compared as objective weighting methods to examine the effect of weighting choice. Entropy emphasized the main quota, producing a quota-focused evaluation. CRITIC gave greater weight to price and price efficiency, accounting for data variation and criterion correlations. Both methods selected Tri Happy 70GB as the best option. The overall rankings were highly consistent, with a Spearman rank correlation of 0.8741, although some alternatives changed positions within the top group. The analysis is limited to a single time snapshot based on published package attributes and excludes measured network performance in Ambon City. In practice, the framework is transparent, replicable, and can be extended with constraints such as maximum budget and minimum validity requirements. The study contributes a controlled comparison of Entropy and CRITIC effects while keeping TOPSIS constant.
