Abstract

PT Barokah Galangan Perkasa is a company located in East Kalimantan that is engaged in the manufacturing, repair, and maintenance of ships. The welding activity is the most dominant in shipbuilding, but the implementation of the occupational health and safety (OHS) system is not optimal. There have been several work accidents in the upper accommodation and cargo oil tank areas, such as falling from a height, being hit by welding sparks, and an electrical short circuit. The working conditions in this area are quite risky. Therefore, research on risk analysis is needed. HIRARC is a method for identifying a problem that is assessed at risk based on the likelihood and severity where the results of the assessment can determine the level of risk and give risk control for each work activity. Research results show that there were 40 potential hazards in the upper accommodation area with 77% low risk level, 12% moderate risk level, 8% high risk level, and 3% very high risk level. While in the cargo oil tank area there was 37 potentials hazard with 84% low risk level, 13% moderate risk level, and 3% high risk level. By knowing the risk level, companies can identify work activities that require prioritized improvement. They can also determine appropriate control to prevent the occurrence of such risks. Risk control in the upper accommodation area can be achieved through the implementation of administrative controls, utilization of PPE, and technical engineering controls.

Abstract

Indonesia is the world's largest producer of palm oil, with millions of hectares of plantations. However, along with the growth of the palm oil industry, various challenges and issues related to the worker welfare have emerged. One important issue is musculoskeletal disorders or health problems associated with work in palm oil plantations. Workers in palm oil plantations are often exposed to heavy and repetitive work conditions, such as carrying heavy loads, performing monotonous movements, and working in non-ergonomic positions. These factors can increase the risk of musculoskeletal disorders, such as back pain, shoulder pain, neck pain, and other health issues. Therefore, this research aims to evaluate existing musculoskeletal disorders and provide recommendations for improvement and management of ergonomic risks in PT. DSN in Muara Wahau. The research methods include direct observation of palm oil farmers during their work, structured interviews to gather information on complaints and ergonomic risks, and the use of ergonomic analysis methods in accordance with the SNI 9011:2021 standard. The data obtained will be analyzed to identify ergonomic risk factors contributing to musculoskeletal disorders. The results of this study showed that  all of palm oil harvesting workers experienced high risk level on their neck, while all of palm oil transportation workers encountered high risk on their elbow. Stretching or warm-up exercises before and after work were recommended to reduce the risk of injuries caused by non-ergonomic work positions among harvesting workers. Furthermore, redesigning Hook-T was recommended in order to minimize the MSD among palm oil transportation workers.

Abstract

This study aims to analyze service quality at Bank ‘X’ by applying the Banking Service Quality (BSQ) method. Service quality is a crucial factor in maintaining customer satisfaction and preserving the bank's competitiveness against other banks. The BSQ method is used to identify the dimensions of service quality that have the most influence on customer perceptions of services at Bank ’X’. This research employs a quantitative approach by collecting data through questionnaires distributed to customers of Bank ‘X’, the collected data are then analyzed using statistical techniques such as factor analysis to identify service quality variables that emerge from customer perceptions. Additionally, regression analysis is conducted to measure the influence of each dimension on customer satisfaction. The results of this research indicate a negative gap in the access variable, while the other variable experience a positive gap. Negative gap results are also found in the attributes of "customer service assistance," "number of tellers and customer service staff," and "queues at tellers and customer service." The Pearson product-moment correlation test results show that all variables are related to customer satisfaction. The influence of service quality on customer satisfaction at Bank ‘X’ is represented by the equation Y = -5.708 + 0.290X1 + 0.305X2 - 0.423X3 + 0.422X3 + 0.341X5 + 0.35X6. The results of the F-statistic test indicate that all service quality variables significantly influence customer satisfaction simultaneously. The t-statistic results reveal that the reliability variable does not have a significant partial effect on customer satisfaction, whereas the other variable have a significant partial effect on customer satisfaction.
