Abstract

The construction industry is one of the sectors with a high level of risk, particularly concerning Occupational Health and Safety (OHS). These risks may include potential workplace accidents, schedule delays, cost overruns, asset damage, and disruptions to work quality. Understanding and managing these risks is crucial to minimizing the negative impacts that may arise during project execution, including in South Sumatra Province. This study aims to identify risks that emerge due to the lack of OHS implementation in construction projects, in order to formulate strategies for risk prevention and mitigation. Data collection was carried out by distributing questionnaires to respondents from 5 building construction projects and 8 civil construction projects in South Sumatra, involving a total of 31 respondents.The analysis reveals that the highest risks in building construction projects include falling from heights, injuries caused by manual tools, and being struck by heavy equipment. Based on the data, the risk identification indicates that falling from heights is the most frequent incident. These three risks consistently received a mean score of 5, indicating a very high category in risk assessment. The causes of these risks include the failure to use Personal Protective Equipment (PPE) and unsafe, hazardous, or unhealthy workplace conditions. Risk control measures that are routinely implemented include the installation of OHS signage and safety lines, regular OHS communication with workers, routine inspections and evaluations of tools and heavy equipment, and the availability of work methods and programs. To further reduce these risks, risk control is carried out following the hierarchy of controls, beginning with Personal Protective Equipment (PPE), Administrative Controls, Engineering Controls, Substitution, and Elimination.

Abstract

Abstrak   Aspal beton padat memiliki permeabilitas rendah sehingga air hujan sulit meresap, yang berpotensi menimbulkan genangan dan menurunkan keselamatan lalu lintas. Aspal beton porus dikembangkan sebagai alternatif dengan struktur gradasi terbuka yang menghasilkan rongga saling terhubung, sehingga memungkinkan air mengalir ke lapisan bawah perkerasan. Namun, karakteristik ini umumnya berdampak pada penurunan stabilitas campuran. Penelitian ini bertujuan menganalisis pengaruh jenis aspal dan gradasi agregat terhadap kinerja mekanik dan hidrologis aspal beton porus. Variasi yang digunakan meliputi aspal termodifikasi AKAP PG-76 dan aspal konvensional PEN 60/70, serta gradasi agregat AAPA dan British Standard. Benda uji disiapkan dari kombinasi kedua jenis aspal dan gradasi, kemudian diuji menggunakan pengujian Marshall, Cantabro, dan permeabilitas. Hasil penelitian menunjukkan bahwa penggunaan AKAP PG-76 meningkatkan stabilitas Marshall dan ketahanan keausan campuran, sedangkan variasi gradasi agregat berpengaruh signifikan terhadap nilai permeabilitas. Temuan ini memberikan dasar teknis dalam pemilihan kombinasi material untuk meningkatkan kinerja aspal beton porus.

Porous asphalt concrete has been developed as an alternative by employing an open-graded structure with interconnected voids, allowing water to drain into underlying pavement layers. However, this characteristic often leads to lower mixture stability compared to conventional asphalt concrete, requiring a balance between mechanical and hydraulic performance. This study analyzes the effects of asphalt type and aggregate gradation on the mechanical and hydrological performance of porous asphalt concrete. The variables include modified asphalt AKAP PG-76 and conventional asphalt PEN 60/70, as well as AAPA and British Standard aggregate gradations. Specimens were prepared from combinations of asphalt types and gradations and evaluated using Marshall stability, Cantabro abrasion resistance, and permeability tests. The results indicate that AKAP PG-76 improves Marshall stability and abrasion resistance, while aggregate gradation plays a dominant role in controlling permeability. These findings provide insight into optimizing porous asphalt mixtures through binder modification and gradation design.   Keywords: Porous asphalt concrete; Marshall stability; Permeability; Aggregate gradation; Cantabro test
