Abstract

Borneo Conblock Mandiri faces significant challenges in its monthly production, with an average of more than 50,000 paving units, but the number of defects exceeds 4,500 units. These defects include cracks, breaks, and uneven or jagged surfaces. To overcome this problem, a quality control analysis is proposed using the seven tools method to reduce defects and improve overall product quality. The research results show that in the production of Holand-type paving, the primary defects include 4,965 units (53%) cracks, 2,661 units (29%) broken, and 1,660 units (18%) the surface is not smooth. Human and machine factors were identified as the leading causes of defects in paving. The proposed solution is the addition of a foreman as an additional supervisor, especially in the production process. The new foreman inspects the material more intensively before it is put into the mixer. Hopefully, these steps can reduce the number of defects and improve overall product quality. The expected result of this research is that it can positively impact the productivity and reputation of Borneo Conblock Mandiri. By addressing the root causes of defects and implementing appropriate solutions, companies can improve their production processes and deliver higher-quality products in line with market demands.

Abstract

Occupational Health and Safety (OHS) is a systematic effort aimed at protecting workers from the risks of accidents and work-related diseases. The implementation of OHS integrated with risk management helps identify, evaluate, and control potential hazards effectively in the workplace. This study was conducted at PT. Sarana Sampit Mentaya Utama, Balikpapan Branch, a company engaged in asphalt production. The main objectives of this research were to identify potential hazards, determine appropriate control measures, and evaluate the role of the Job Safety Analysis (JSA) method in supporting OHS. The research method used is JSA, which involves identifying each work step, determining the likelihood and severity of risks, and calculating the risk rating to assess the level of risk. The results showed that there are three potential hazards with a medium-risk category, namely in the activities of raw material mixing, quality control, and asphalt distribution. Additionally, three potential hazards with a low-risk category were found in the processes of raw material weighing, raw material transfer, and pump line valve opening. Recommended control measures to reduce risks include the use of appropriate personal protective equipment (PPE) for each task, improving work facilities and infrastructure, and implementing proper load lifting procedures. The application of JSA has proven effective in raising the company's awareness of potential risks in the workplace. This has led to the implementation of better preventive measures, ultimately contributing to the creation of a safer, healthier, and more productive work environment.

Abstract

This study aims to analyze the causes of component failure in the Power Train system of unit OHT773E CO2278 at PT. Cipta Kridatama, Samarinda, using the Root Cause Failure Analysis (RCFA) method. The Power Train system is responsible for transferring power from the engine to the final drive and other components, making it critical for the operational success of heavy equipment. Therefore, optimal maintenance is essential to prevent fatal failures that could impact the unit's performance. Based on the analysis, the dominant cause of failure is human factors, particularly technician negligence during component installation. This negligence results from a lack of understanding of the procedures and specifications recommended by the manufacturer, leading to incorrect installation of components. This failure impacts the achievement of the component’s expected lifetime, thus shortening the operational life of the components and increasing the risk of more severe damage. This also leads to higher repair costs and reduced unit productivity, resulting in longer downtime. To address this issue, several preventive measures are recommended, such as regular training for technicians to enhance their understanding of correct procedures and specifications, as well as the importance of following manufacturer guidelines during every maintenance and installation process. Additionally, it is advised to conduct routine discussions between technicians and supervisors to ensure that every maintenance step and installation complies with the established procedures. Increased oversight of the installation and maintenance process is also necessary, along with periodic rejuvenation of components to ensure the optimal performance of the Power Train system. Strengthening Preventive Maintenance (PM) practices is also crucial to minimize future damage potential. Implementing these solutions is expected to enhance the reliability of the Power Train system, extend component lifespan, and reduce failure frequency, ultimately improving the overall efficiency and productivity of the company.

Abstract

The Terminal Loading Area (TLA) API at PT Pertamina Hulu Mahakam functions as a facility for processing oily water before being discharged into the environment. One of the main issues faced is the accumulation of thick floc (oil clumps) due to high emulsions in crude oil, along with the malfunctioning water spray valve on line 1, causing operators to resort to manual spraying using hydrant water. This increases the risk of exposure to hazardous chemicals such as Benzene, Toluene, and Xylene (BTX), which poses a health threat to workers. Therefore, improvements to the water spray system are needed to reduce BTX exposure and enhance the effectiveness of oil-water separation. This study aims to analyze the effectiveness of proposed improvements to the water spray system to reduce BTX exposure and improve the efficiency of oil-water separation. The methodology used includes literature review, field study, and technical testing. Proposed solutions include replacing or repairing the damaged water spray valve, adding piping networks to compartment 2 to distribute water more evenly, and using treated water (produced water) to optimize the system and reduce reliance on hydrant water. The results of the study indicate that replacing or repairing the water spray valve, adding piping networks, and using produced water effectively reduce BTX exposure while maintaining oil recovery effectiveness. The trials also showed that using the Oil Pump (P-3230 & P-3235) provides optimal pressure (8–9 barg) for water spray, compared to the less effective Water Pump (P-3200 & P-3205). Implementing these solutions is expected to reduce BTX exposure for workers, improve oil-water separation efficiency, and contribute to a safer and more efficient working environment.

Abstract

This study analyzes the effectiveness of implementing predictive maintenance (PdM) on the final drive components of the Komatsu PC200-8 unit at PT. Antareja Mahada Makmur, Site PT. Multi Harapan Utama, East Kalimantan, in an effort to reduce downtime and operational losses. Before the implementation of PdM in 2022, there were 12 repair cases for the final drive with a total downtime of 772.1 hours, repair costs amounting to IDR 310.6 million, rental income loss of IDR 208.03 million, and total losses of IDR 518.63 million. In 2023, during the PdM transition phase, the number of cases decreased to 4, with a total loss of IDR 252.05 million, although downtime remained high (714.6 hours) due to the limited scope of PdM implementation on certain units and components. In 2024, with full PdM implementation, the number of repair cases decreased to 5, with total downtime of only 96 hours and losses of IDR 45.75 million. The cost of PdM implementation for the year was only IDR 21.9 million. As of July 2025, no further damage to the final drive has been recorded, demonstrating a significant improvement in equipment reliability. The reduction in total losses from 2022 to 2024 amounted to IDR 472.88 million, indicating PdM’s effectiveness in avoiding significant costs through condition monitoring methods such as oil analysis, magnetic plug rating, thermal inspection, and oil leak testing (floating seal). The findings of this study confirm that PdM is effective in reducing downtime, repair costs, and enhancing asset management in the mining sector. It also improves equipment reliability and overall operational efficiency, proving PdM to be a successful strategy in reducing losses, increasing productivity, and supporting the sustainability of company operations.
