Abstract

Desa Lau Bakeri merupakan salah satu desa di Kecamatan Kutalimbaru, Kabupaten Deli Serdang dimana 30 KK diantaranya menjalankan usaha budi daya jamur tiram yang sesuai dengan kelembaban di daerah tersebut. Mitra pengabdian sudah 10 tahun menjalankan usaha budidaya jamur tiram yang sebagian besar masih dilakukan secara manual, termasuk pemadatan media tanam (baglog) yang memakan waktu cukup lama dan butuh pekerja upahan dengan gaji Rp. 200.000,- per hari. Permintaan jamur masih cukup terbuka akan tetapi karena keterbatasan lahan dan tenaga kerja belum semua dapat dilayani. Pembuatan mesin pengepres baglog dan pelatihan penggunaan mesin diharapkan dapat menjadi solusi yang dapat mengatasi permasalahan pada pembudidaya jamur tiram. Pada saat pemberian alat dan sosialisasi penggunaan mesin pengepres baglog jamur ini, masyarakat sangat menyambut baik, dan berharap kemitraan pegabdian masyarakat seperti ini terus berlanjut.

Abstract

This study examines the effectiveness of the Inquiry-Based Learning model in enhancing students’ conceptual understanding of the SMAW and GMAW welding processes, an area that remains underexplored in vocational education. The research addresses the gap between the development of procedural skills and the acquisition of conceptual reasoning by investigating whether inquiry-oriented instruction can promote deeper cognitive engagement. A quasi-experimental design was implemented involving two intact groups, with the control group receiving conventional teacher-centered instruction and the experimental group experiencing structured IBL activities. Data were collected through pretests, posttests, observations, and semi-structured interviews, and analyzed using paired-sample and independent-sample t-tests, ANCOVA, effect size calculations, and normalized gain measures. The findings reveal that the experimental group demonstrated a substantial and statistically significant improvement in conceptual understanding compared with the modest gains observed in the control group. The intervention produced a very large effect size and a medium-high normalized gain, indicating strong learning effectiveness. Students exposed to IBL were better able to analyze parameter interactions, interpret defect mechanisms, and connect theoretical principles with laboratory outcomes. Overall, the study provides strong empirical evidence that Inquiry-Based Learning is a highly effective pedagogical approach for strengthening conceptual mastery in welding technology and should be considered for broader integration into vocational curricula.
