Abstract

PT LSM is a shipping company committed to focusing on providing integrated maritime services to support the oil & gas industry, PT LSM has a variety of offshore vessels to support these activities. LSM's shipping area is a rig area, where the area has a high level of danger and risk, therefore an adequate ship is needed both in crew and equipment on board. Especially in the piping system on board, if a leak occurs it can cause fatal things such as engine damage to an explosion and can cause work accidents such as fire and death. To minimize work accidents, risk hazard identification and risk control are made in each job, especially in piping work, namely pipe welding using the HIRADC method. This study used a descriptive qualitative method, in which the authors conducted field observations, interviews, and distributed questionnaires. The results of risk hazard identification, risk assessment and risk control will be entered in the HIRADC (Hazard Identification, Risk Assessment, and Determining Control) table. The conclusion of this study is that 43 hazards and 47 risks have been identified in pipe welding work. In the initial control, the low risk level was 42 risks (89.36%), the medium risk level was 5 risks (10.63%), and the high-risk level was 0 risks (0%). After further control of the identified risks, the risk level of medium risk (10.63%) has changed to low risk, so that all risk levels of the LSM Provider's ship pipe welding work have changed to a low risk level with a total of 47 risks (100%)). The controls used in pipe welding work are substitution, administration, and personal protective equipment (PPE).

Abstract

Container terminals are critical nodes in global trade, where productivity hinges on the efficiency of handling equipment like container cranes. At PT. Kaltim Kariangau, a terminal jointly managed by PT. Pelindo and the East Kalimantan provincial government, operational challenges persist despite infrastructure enhancements. In 2023, an additional crane was introduced to the terminal, increasing the total to three. However, issues such as prolonged idle times and equipment malfunctions adversely impacted crane efficiency. This research evaluates crane performance using BCH (Box/Crane/Hour) and BSH (Box/Ship/Hour) metrics to assess their effect on loading and unloading productivity. The analysis reveals that in 2023, the average crane performance was 27 boxes/hour, a level classified as good. Paradoxically, overall productivity declined post-crane addition compared to prior operations. Using regression analysis, the study identifies a strong positive correlation (R = 0.7316) between crane performance and terminal productivity, with a coefficient of determination (R²) indicating that crane efficiency accounts for 54% of productivity variations. The findings highlight that improved crane performance directly enhances operational output, where each unit increase in BCH corresponds to a 1.809-unit rise in productivity. Hypothesis testing confirms that crane performance significantly influences loading and unloading efficiency. These results underscore the need for effective equipment utilization and maintenance strategies to optimize terminal operations. The research concludes that while infrastructure upgrades are essential, addressing operational inefficiencies is critical to achieving sustainable productivity improvements.

Abstract

Performance and safety behavior are crucial in a company such as PT PLN (Persero) UP3 Parepare. Therefore, research is needed to determine the hygiene factors influencing worker performance and safety behavior in achieving company goals without work accidents. The data collection technique used in this research involves primary data in the form of a questionnaire. Questionnaires were distributed to respondents, and then processed using the help of Smart PLS 4.0. The analytical tool used is Partial Least Square (PLS), a multivariate statistical technique that compares several dependent variables. The research results show that factors that significantly influence worker performance are working conditions, supervision, and interpersonal relationships. Meanwhile, factors that do not have a significant influence on worker performance are salary, company policy, and administration and supervision. Working conditions and supervision have a significant effect on worker safety behavior. Factors that do not have a significant influence on worker safety behavior are company policies and administration, salary, and interpersonal relationships.

Abstract

The safety of the ship block lifting process is always a serious concern during the assembly of ship blocks. The block/structure and equipment must not be damaged during the lifting process. This study aims to determine the structural response values that occur with various hole diameter sizes of the lifting lug during the ship block lifting process. The object of this research is a ship block from the new construction of the Ferry Ro-Ro 1500 GT. The method used is numerical simulation based on finite element method (FEM) software. The simulation is conducted to obtain the stress and deformation values for each size of the lifting lug. The selected ship block load is the largest ship block load, which is 52,380 tons. The number of lifting lugs used in the simulation is 5, with varying diameters of 53, 58, 63, 68, and 73 cm. Based on the simulation results, the diameter of 63 mm gets the minimum normal and shear stress figures. While the minimum von misses stress figure is shown by the variation of the diameter of 73 mm. While the smallest deformation figure is shown by the variation of the diameter of 53 mm. In general, all variations of lifting lug holes can still be applied with the note that the weight of the load must be considered.
