Pelatihan Identifikasi Kerusakan Struktural Dini Bangunan Gedung pada Lahan Gambut untuk Mitigasi Risiko Runtuh

Abstract

This community service activity aimed to enhance the competency of structural consultants in identifying early structural damage indicators on peat-soil buildings in West Kalimantan as a preventive measure for collapse risk mitigation. The activity was conducted at CV. Bhipraya Cipta, Pontianak, involving seven civil engineering professionals with three to twelve years of experience. The methodology combined participatory education, demonstration-based training, technology dissemination, and focus group discussion (FGD), organized in three phases: pre-test baseline assessment, training implementation, and post-test evaluation. Training sessions covered differential settlement mechanisms in peat foundations, visual damage classification based on SNI 1726:2019 and SNI 2847:2019, failure mode and effect analysis (FMEA) for structural risk prioritization, and practical field inspection checklist exercises using documented peat-building case photographs. Evaluation using the normalized gain method (Hake, 1998) yielded an overall mean N-gain of 0.63 (moderate category), with individual scores ranging from 0.60 to 0.67, indicating consistent competency improvement regardless of experience heterogeneity. The highest gain was recorded for crack pattern identification (g = 0.69) and the lowest for failure mode prioritization (g = 0.58). The FGD identified three critical procedural gaps: absence of standardized inspection protocols, unfamiliarity with damage severity thresholds specific to peat foundations, and lack of structured reporting procedures. The activity produced a validated field inspection checklist covering 35 items across five structural element groups as a practical outcome for direct implementation in routine building inspections in West Kalimantan peat areas.
