Abstract

AbstrakBudidaya lele di Kecamatan Tebing Tinggi, Kabupaten Serdang Bedagai, menghadapi tantangan efisiensi penggunaan pakan yang berdampak pada tingginya biaya produksi dan rendahnya hasil panen. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan efisiensi budidaya lele melalui pelatihan manajemen pakan dan penerapan teknologi pencampur pakan otomatis. Sasaran kegiatan adalah Kelompok Tani Lele "Kuta Baru" dengan jumlah peserta 20 orang. Metode pelaksanaan meliputi sosialisasi, pelatihan teknis penggunaan pH Meter dan TDS Meter, aplikasi alat pencampur pakan otomatis berkapasitas 15 kg, serta pendampingan dan evaluasi hasil. Hasil program menunjukkan peningkatan efisiensi penggunaan pakan sebesar 18%, kenaikan rata-rata bobot panen 12%, dan 90% peserta mengadopsi teknologi baru. Kegiatan ini berkontribusi dalam meningkatkan produktivitas, efisiensi biaya, dan pengetahuan petani dalam budidaya lele yang berkelanjutan. Kata kunci: budidaya lele; efisiensi pakan; teknologi tepat guna; pelatihan; serdang bedagai AbstractCatfish farming in Tebing Tinggi Subdistrict, Serdang Bedagai Regency, faces the challenge of feed use efficiency which has an impact on high production costs and low yields. This community service activity aims to improve the efficiency of catfish cultivation through feed management training and the application of automatic feed mixing technology. The target of the activity is the "Kuta Baru" Catfish Farmer Group with a total of 20 participants. The implementation method includes socialization, technical training on the use of pH Meter and TDS Meter, application of automatic feed mixing equipment with a capacity of 15 kg, as well as mentoring and evaluation of results. The program results showed an 18% increase in feed use efficiency, a 12% increase in average harvest weight, and 90% of participants adopted the new technology.

Abstract

A persistent mismatch between vocational education outcomes and industry requirements presents a global challenge, often stemming from limited student exposure to modern industrial technologies. This study addresses the gap by designing, developing, and validating a cost-effective Variable Speed Drive (VSD) trainer as a practical and pedagogically appropriate learning medium. The research employed the waterfall development model, encompassing a structured process of needs analysis, system design, hardware implementation, and comprehensive evaluation to ensure the trainer’s feasibility and instructional effectiveness. The evaluation phase included expert validation and practicality testing with end-users. Validation results showed the VSD trainer and accompanying job sheet were rated “Highly Suitable,” with average scores of 3.67 from media experts and 3.63 from subject matter experts on a four-point Likert scale. Practicality scores were 3.61 from teachers and 3.38 from students, indicating strong usability and instructional relevance in real classroom settings. The findings suggest that the VSD trainer is a validated, scalable, and effective instructional solution that improves students’ conceptual understanding, practical skills, and motivation. These outcomes align vocational training more closely with industry demands. Further development integrating IoT-based remote monitoring is recommended to enhance the trainer’s functionality and relevance in digitally supported learning environments.
