Abstract

This study aims to assess workers' compliance with Occupational Safety and Health (OSH) implementation and risk control using Hazard Identification Risk Assessment and Risk Control (HIRARC) and Job Safety Analysis (JSA) methods on tower cranes to reduce workplace accident risks. Using a quantitative descriptive method through questionnaires, interviews, and field observations, the study found that workers' compliance is generally high but still not optimal, requiring further actions such as regular monitoring, safety patrols, and preventive measures. Risk identification using HIRARC identified 21 high-risk variables and 1 medium-risk variable. Risk control was implemented through the Hierarchy of Control and JSA methods, helping reduce potential hazards and improve safety performance on tower crane operations in the workplace.

Abstract

This study aims to explore the application of Lean Construction methods to reduce waste in construction projects in West Java. Inefficiencies often arise from seven types of waste: waiting, inventory, motion, overproduction, inappropriate processing, transportation, and defects. Data were collected through a quantitative approach, by distributing questionnaires to construction experts in the West Java region. Data analysis utilized a Likert Scale to determine the intensity level of each waste category. From 14 respondents, the two highest waste categories were Waiting (weather disturbances) and Transportation (the distance of suppliers to the project site). Root cause analysis was conducted using the 5 Why method with experienced respondents. The main issues identified were poor planning, inefficient logistics, and improper supplier selection.
