Abstract

The rapid growth in the use of electric motorcycles has increased the need for a damage diagnosis system that is fast, accurate, and easily accessible. The process of identifying faults, which still relies on manual inspection, often requires considerable time and depends heavily on the expertise of technicians. This study aims to develop a web-based intelligent system capable of automatically diagnosing electric motorcycle faults using the Naïve Bayes method. This method is chosen due to its ability to perform probabilistic classification with good accuracy, even when dealing with limited data. The developed system utilizes symptom data and types of faults as the basis for probability calculations to determine the most likely damage. The system development process includes data collection, model design, algorithm implementation, and system testing. The testing results indicate that the system is able to provide fast and consistent diagnostic recommendations based on the symptoms input by users. With the implementation of this system, it is expected to assist both users and technicians in conducting initial identification of electric motorcycle faults more efficiently, thereby accelerating the repair process and reducing the potential for diagnostic errors.

Abstract

Era digitalisasi menuntut kecepatan, efisiensi, dan daya tarik visual dalam penyampaian informasi publik di lembaga pendidikan. Namun, Madrasah Aliyah Swasta (MAS) Imam Muslim di Kecamatan Sei Rampah masih bergantung pada media informasi konvensional berbasis cetak yang tidak efisien, membutuhkan biaya berulang, serta mengurangi estetika lingkungan sekolah. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk melakukan transfer teknologi tepat guna berupa media informasi digital running text menggunakan panel LED Dot Matrix P5 berbasis mikrokontroler HD-WF2 dengan sistem kontrol nirkabel (Wi-Fi). Metode pelaksanaan yang digunakan adalah action research dan transfer teknologi yang meliputi lima tahapan: persiapan, perancangan/perakitan, instalasi/pengujian, pelatihan/pendampingan, serta evaluasi. Kegiatan pelatihan yang dilaksanakan pada 19 Mei 2026 ini diikuti oleh 20 peserta yang terdiri dari guru dan siswa. Hasil evaluasi menunjukkan adanya lonjakan pemahaman dan keterampilan peserta secara signifikan sebesar 86,25% (diukur dari perbandingan pre-test dan post-test). Sistem ini berhasil memangkas waktu birokrasi penyampaian informasi yang awalnya memakan waktu 1–3 hari menjadi kurang dari 2 menit secara real-time. Dapat disimpulkan bahwa implementasi teknologi ini berhasil meningkatkan modernitas visual madrasah, meningkatkan kemandirian teknologi SDM sekolah, serta menghemat anggaran operasional melalui penerapan paperless system.

Abstract

Media pembelajaran merupakan komponen kunci dalam proses belajar mengajar, berperan sebagai alat bantu untuk memahami konsep atau materi. Kendala seperti waktu belajar terbatas di kelas dan kurangnya referensi seringkali menyebabkan pemahaman siswa terhadap materi menjadi terbatas pula.Meskipun pembelajaran berbasis internet saat ini sudah banyak diterapkan, masih banyak guru yang belum mampu memanfaatkannya secara optimal. Bahkan, sebagian guru masih belum terampil dalam mengoperasikan komputer. Sebagai solusi atas permasalahan ini, diadakanlah bimbingan teknis pembuatan blog untuk guru dan staf di SMK Negeri 1 Pematang Siantar. Kegiatan pengabdian masyarakat ini dilaksanakan pada Rabu, 24 Mei 2025 di sekolah tersebut dan diikuti oleh 20 peserta guru serta staf terkait.Berdasarkan evaluasi, kegiatan ini memberikan hasil dan manfaat yang signifikan, terutama dalam meningkatkan pengetahuan serta keterampilan para guru dalam membuat blog dan mengunggah materi pembelajaran. Selain itu, blog ini menjadi sarana berbagi materi ajar antar guru dan juga dengan siswa, karena materi dapat diunduh oleh semua pihak di lingkungan sekolah

Abstract

Academic administration services support students through course registration, access to grade records, and the processing of academic documents. This study examines the association between academic administration service quality and student satisfaction at Politeknik Gihon Pematangsiantar and discusses its implications for academic information systems. A quantitative, cross-sectional observational design was used, with a census covering all 65 students. Data were collected using a closed-ended Likert-type questionnaire comprising 10 service-quality items and six satisfaction items. The analysis included item-validity assessment, internal-consistency reliability, simple linear regression, a coefficient t-test, and the coefficient of determination. All 16 items exceeded the reported validity threshold of 0.2441. Cronbach’s alpha values were 0.841 for service quality and 0.811 for student satisfaction. The regression equation was Y = 2.234 + 0.534X, with t = 11.859 and p < 0.001, indicating a statistically significant positive association. The model reported R = 0.831 and R² = 0.691, meaning that service quality explained 69.1% of the observed variance in satisfaction, while 30.9% remained unexplained. These findings do not establish causality because the study used cross-sectional, self-reported data from a single institution. Verification of the remaining residual diagnostics is also required. The findings inform candidate priorities for academic information systems, including online registration, access to academic records, document-request tracking, and consistent service information. These priorities are recommendations for future development and evaluation; no administration application was developed or evaluated in this study.
