Abstract

Project schedule delays and the high risk of workplace accidents remain major issues in construction project management, particularly those related to ineffective supply management and insufficient expert workforce skills. This study aims to analyze the effect of supply management and expert workforce skills on workplace accident prevention, with schedule delays as a mediating variable at PT Daidan Group. The research design employs a quantitative descriptive approach using a survey method. The population consists of technical workers and experts, with a sample of 157 respondents selected using purposive sampling based on the Slovin formula. Data were collected through structured questionnaires using a Likert scale. The data analysis technique applied is Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that supply management and expert workforce skills have a positive and significant effect on schedule delays and workplace accident prevention. Schedule delays are also found to have a significant effect on workplace accident prevention and act as a mediating variable between independent and dependent variables. Inventory management and job knowledge dimensions are identified as dominant factors in improving operational effectiveness and workplace safety. These findings suggest that effective supply chain management and enhanced workforce competencies can significantly reduce delays and improve safety performance. The discussion highlights the importance of integrating supply management, human resource development, and project time control in creating a safe and efficient work environment. Therefore, companies are recommended to strengthen inventory control systems, enhance workforce training programs, and optimize project time management to support operational performance and sustainable safety culture

Abstract

Purpose – This study aims to examine sustainability competency development among Indonesian Nautika cadets as a human resource development investment problem, testing whether curriculum-hour allocation, treated as a training-investment decision, explains observed competency gaps and the retraining costs industry subsequently absorbs. Design/methodology/approach – A sequential mixed-methods design surveyed 180 cadets across three sustainability competency domains, modelled the pathway linking multiliteracy instruction to vocational competency through structural equation modelling, and triangulated results against thematic analysis of three stakeholder groups, industry experts, senior lecturers, and post-placement near-graduates, supplemented by a six-week training intervention evaluated against a matched comparison group. Findings – ESG Leadership competency scored lowest of all domains, 2.18 out of 5.00, against zero allocated training hours, while 86.7 percent of industry stakeholders reported retraining every recent graduate within six months of hire. Stewardship orientation was found to mediate the pathway from multiliteracy instruction to vocational competency, and the training intervention produced the largest effect size of any domain tested. Originality/value – This study is among the first to treat curriculum-hour allocation explicitly as a human resource development investment decision in maritime vocational education, and to triangulate industry, lecturer, and near-graduate accounts of the resulting training gap, reframing curriculum-industry misalignment as a correctable allocation problem rather than a fixed formation cost.
