Alignment Model of Expectations with Actual Lifetime of Mainpump Components on Heavy Equipment

Anggi Febrianto, Mokh Suef, Muhammad Saiful Hakim — Mon, 11 Aug 2025 00:00:00 +0700

This research focuses on the importance of optimal machine performance in various industrial sectors, emphasising the reliability of each component as a crucial factor in maintaining productivity and operational efficiency. In this context, specific research was conducted to analyse the difference between the expected life of components and the actual life achieved in the field. There is a significant knowledge gap associated with the mismatch between expected and actual component life, potentially leading to unexpected increases in operating costs and decreases in efficiency. This study used survey methodology and linear regression analysis to evaluate the relationship between the expected and actual age of mainpump components on Komatsu PC200 units. The main results showed that the actual life of the components tended to be lower than the expected life, with an average gap of 3,257 hours, indicating the need for adjustments to maintenance and replacement strategies. The analysis also revealed that factors such as severe operational conditions and suboptimal maintenance methods contributed to this mismatch. The implications of this study point to the importance of implementing a more adaptive and data-driven maintenance strategy to improve operational efficiency and minimise unexpected downtime.

Analysis of Track Adjuster Damage On 20 Ton Class Excavators

Mon, 11 Aug 2025 00:00:00 +0700

The track adjuster is an important component on the excavator wheel that serves to adjust the tension of the track chain and reduce drag on the front of the excavator unit. When the excavator wheels are active (loading or digging), the track adjuster becomes the main support, especially when moving. The undercarriage of the excavator has to deal with road or soil structure resistance as it is in direct contact with the surface. A wear and tear analysis of the track adjuster shaft on industry Y's excavator X revealed several problems: broken spring, track piston with scratches, leaking seal and rusted rod. Corrective measures involved replacing the damaged components with new ones. In addition, routine maintenance includes cleaning the unit to facilitate checking the undercarriage, especially the track adjuster. With proper maintenance, the life of these components can be extended and excavator performance optimized.

Development of an Internet of Things-Based Monitoring System for Periodic Maintenance of Vehicles and Heavy Equipment with Integrated Reporting and GPS Features

This study aims to develop an Internet of Things (IoT)-based hourmeter monitoring system to improve the efficiency and accuracy of periodic maintenance for vehicles and heavy equipment. The system is designed to integrate with a website that enables real-time monitoring of operating hours, reporting, and maintenance notifications. Testing was conducted on one light vehicle and one heavy equipment unit over a period of four days. The developed system was able to accurately record operating time, provide maintenance notifications via alarms, and monitor the unit’s location and performance using GPS data. The test results showed that the system successfully recorded travel distance and average speed, with the light vehicle achieving 14.2 km and 11.9 km/h, while the heavy equipment recorded 1.98 km and 7.17 km/h. The integration of hourmeter monitoring and GPS features proved to enhance supervision effectiveness and maintenance schedule prediction, thus potentially reducing the risk of damage and downtime. This system offers an innovative solution that can be adopted in the heavy equipment industry to support more optimal maintenance management.

The Evaluation Of DC Generator Selection In Micro-Scale Portable Hydropower Systems For Heavy Equipment Energy Supply In Remote Areas: Case Study Of Sumatera River VIII

Muhammad Noviansyah Nugraha, Mutiara Putri — Mon, 11 Aug 2025 00:00:00 +0700

This study results in the performance of a DC generator in a portable hydroelectric power plant (PLTA) system designed using an Archimedes screw turbine. The main focus lies in the balance between the turbine's power capacity and the generator's ability to generate electrical energy efficiently. Based on the test results, there is a significant alignment between the theoretical power of the turbine (664.2 W) and the actual power produced by the generator (150 W). This evaluation aims to provide recommendations for selecting the right generator for a microhydro power plant system.

System Integration (ISO 50001) with Chi-Square Test Combination for Heavy Equipment Operational Energy Use Management Analysis at Port Terminal Company

Mon, 11 Aug 2025 00:00:00 +0700

Port terminal companies play an important role in the growth of international trade, with more than 85% of global cargo traffic transported via sea routes and ports. As international trade continues to grow in line with the increasing use of energy, it is necessary to implement energy management strategies to maximize energy utilization. An analysis of the energy management maturity level of a port terminal company based on ISO 50001, combined with a Chi-square test, was carried out to evaluate the actual use of fuel oil (BBM) in equipment. The results showed a maturity level value of ≥ 4 and a significant value in the Chi-square test, indicating an ideal condition for energy management in industrial companies. On the other hand, there is a fluctuating trend in the actual fuel oil usage ratio. This indicates that the company needs to regularly evaluate the alignment between managerial policy-making and actual field data, enabling the company to promptly address any deficiencies occurring on site.
