Abstract

This study aims to identify risks arising in housing construction projects, particularly those related to budget overruns, and to develop mitigation strategies to ensure that projects run according to plan in terms of cost, time, and resources. The methods used are the Project Management Life Cycle (PMLC) to map the project stages from initiation to closure, and the House of Risk (HoR) to identify risk events and risk agents. The novelty of this study lies in the development of difficulty analysis in HoR, which focuses on three main aspects —cost, time, and resources — that have not been explicitly described in previous studies. The results show that the project experienced a cost increase from IDR 150 million to IDR 165 million due to dominant risks, including misinterpretation of design drawings, fluctuations in material prices, and work delays. Through HoR analysis, priority risks were successfully identified, and mitigation strategies were developed in the form of team training to improve design understanding, control of material usage, and the implementation of contingency planning. This research contributes academically by modifying the HoR method with difficulty analysis based on cost, time, and resources, and integrating it with PMLC. It also provides practical guidance to contractors and project managers on anticipating and managing risks more effectively, thereby improving cost efficiency, timeliness, and resource optimization in housing construction projects.

Abstract

Traditional palm sugar production faces various risks such as material contamination, occupational accidents, and procedural inconsistencies that reduce product quality and production safety. Indonesia’s national sugar trade deficit reached 5 million tons in 2023, highlighting the urgent need for risk mitigation in this sector. This study aims to identify, measure, and prioritize risks across 22 stages of the palm sugar production process using the FMEA–Risk Matrix approach, supported by mitigation strategies focused on occupational safety and product quality. A descriptive research method was applied through field observations and interviews. Each potential risk was evaluated using Severity, Occurrence, and Detection scores and then mapped using the Risk Matrix. The analysis identified five main risks, with the highest RPN found in the risk of animal or ant bites (R4 = 175), followed by injury from cutting tools (R5 = 112) and falling from trees (R3 = 96). Most risks were categorized as medium (45%), followed by low (39%) and high (16%). The most dominant mitigation efforts (61%) included routine container cleaning, use of heat-resistant clothing and Kevlar gloves during cooking, and daily monitoring of PPE compliance with a minimum target of 90%. This integrated approach effectively identifies and prioritizes risks in palm sugar production, while enhancing worker safety and product quality. The use of heat-resistant PPE and hygienic procedures has been proven to significantly reduce burn injuries and material contamination. This study expands the application of industrial risk management to traditional agroindustry, offering a measurable mitigation model for palm sugar production and supporting efficiency and sustainability in the national sugar supply chain.
