ABSTRACT

This study aims to identify, assess, and control occupational safety and health (OSH) risks in the construction project of Basko City Mall Padang using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method and Job Safety Analysis (JSA). A quantitative approach was employed through a questionnaire survey involving 30 field workers engaged in foundation, sloof, and column activities. Risk assessment was conducted using the Severity Index (SI) to quantify the probability and impact of hazards, followed by classification using a risk matrix. The findings revealed 55 potential hazards, comprising 21.8% low risk, 20% moderate risk, 54.5% high risk, and 3.6% extreme risk. Recommended control measures include the use of personal protective equipment (PPE), implementation of safe work procedures, routine supervision, and proper management of tools and work areas. The study highlights that systematic OSH management through HIRADC and JSA is essential to minimize workplace accidents, enhance productivity, and ensure the safety of workers in large-scale construction projects.

A Analysis of Productivity Improvement in the Construction Sector

2025-12-04T13:26:31+00:00

The highly complex problems in the construction sector today are a particular concern and are crucial in resolving current construction conflicts. Poor planning, unclear objectives, ineffective communication, and management and resource issues are the main causes of failure in construction projects. The most common problems are a) unclear inventory, b) irregular workflows, c) lack of employee training and competency development, d) lack of integration of analytical data for communication, e) immature planning, unclear environment, poor budgeting and risk management, f) unmeasurable targets, and g) a large number of human resources who are not yet competent in their respective fields.

This ineffectiveness will certainly affect productivity in construction performance, both from internal and external factors, thereby influencing project implementation, which requires us to provide quality management for the construction project itself and the community. Several solutions to improve construction performance productivity are 1) Regularly updating inventories, 2) Using IT to create structured workflows, 3) Focusing on employee training and development, 4) Integrating analytical data into construction, Setting realistic goals, and targets to be achieved, and 5) Competent human resources. The method used is MANOVA (Multivariate Analysis of Variance) statistics and is realized in SEM (Structural Equation Modeling). The results obtained are an effective model for increasing productivity in the construction sector.
