Abstract

The cement producing industry has a high level of occupational accident risk due to the complexity of the production process and potential hazards at every stage of the work. PT X, faces the challenge of improving occupational safety risk management, especially at the raw material processing workstation. By utilizing the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method, this study aims to provide a systematic risk management solution to minimize work accidents that can impact worker safety and the company's operational efficiency and propose effective risk control measures at raw material processing work. The results of the study are based on a risk assessment in terms of raw material processing there are 13 potential hazards from 6 stages of the raw material processing work process. Each risk level at the raw material processing workstation includes an extreme level of 26%, a high level of 38%, a medium level of 27% and a low level of 9%. Hierarchy of Control method: elimination, substitution, engineering, administration and PPE are used for risk control. Keywords: HIRARC, Occupational Safety, Risk Control

Abstract

General background: Ensuring supply continuity and efficiency in cement distribution is a critical challenge for manufacturing companies. Specific background: PT. S faces a strategic decision between producing Ordinary Portland Cement (OPC) in-house or purchasing from external suppliers. Knowledge gap: Previous studies often assess make-or-buy decisions in general terms but rarely integrate operational simulations with financial feasibility for cement distribution. Aims: This study evaluates the comparative feasibility of in-house OPC production versus external purchasing by analyzing demand forecasting, production capacity, distribution performance, and economic outcomes. Results: Using Discrete-Event Simulation (DES), the study finds that a two-day pre-production strategy meets demand of 1,803 tons with a trailer cycle time of 89.9 minutes and effective loading duration of 7 hours and 35 minutes. Net Present Value (NPV) analysis reveals that the in-house option yields Rp2.16 billion, outperforming the buy option’s negative Rp3.18 billion. Novelty: The integration of DES with NPV offers a robust framework for linking operational efficiency and financial viability in cement supply chain decisions. Implications: The findings indicate that in-house production is the more feasible option, providing higher financial returns, reducing supplier dependency, and strengthening operational resilience. Highlights: In-house OPC production outperforms external purchasing financially. DES + NPV integration provides a novel decision-making framework. Strategy strengthens supply continuity and operational resilience. Keywords: Make or Buy, OPC Cement, Discrete Event Simulation, Distribution Strategy, NPV Analysis

Abstract

General Background: The frozen food industry is expanding rapidly in Indonesia, driven by consumer demand for practical, nutritious, and long-lasting products. Specific Background: However, small and medium-sized enterprises (SMEs) in this sector, such as UD Mitra Abadi in Lamongan, face operational challenges including limited cold storage, fluctuating raw material prices, and inadequate cold chain management. Knowledge Gap: Despite growing awareness of risk management, many SMEs still depend on intuition rather than structured analytical methods, leaving them vulnerable to operational disruptions. Aims: This study applies the House of Risk (HOR) method, integrated with ISO 31000:2018, to systematically identify, analyze, and mitigate operational risks in frozen food production. Results: The analysis identified 15 risk events and 26 risk agents, with key issues such as poor interdepartmental coordination, non-compliance with SOPs, and weak cold chain practices. From 18 proposed preventive actions, six were prioritized based on their Effectiveness-to-Difficulty ratio, including the use of styrofoam packaging, daily briefings, Kanban boards, and 5R principles. Novelty: This study demonstrates a structured, resource-sensitive approach to operational risk management tailored for SMEs in the frozen food sector. Implications: The findings provide practical, scalable mitigation strategies that enhance resilience, efficiency, and competitiveness in similar industries. Highlights: Identified 15 risk events and 26 risk agents in frozen food operations. Prioritized 6 effective preventive actions using House of Risk analysis. Provides practical, resource-sensitive strategies for SMEs’ resilience. Keywords: Frozen Food Industry, Operational Risk, House of Risk, Risk Management, SMEs
