Abstract

This study aims to analyze the effect of teaching experience, educational level, and training on teacher performance. A quantitative approach with a survey method was employed in this research. Data were collected through questionnaires distributed to teachers as research respondents. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The measurement model (outer model) indicates that all research indicators meet the validity and reliability criteria, as reflected by factor loading values, composite reliability, and average variance extracted exceeding the required thresholds. Furthermore, the structural model (inner model) testing reveals that teaching experience and training have a positive and significant effect on teacher performance, while educational level shows a positive but insignificant effect. The coefficient of determination indicates that teacher performance can be moderately explained by the independent variables included in the model. These findings suggest that practical experience and competency enhancement through training play a more dominant role than formal educational background in improving teacher performance. The results are consistent with Abdul Kadir’s findings, which emphasize that professional competence development and teaching experience significantly contribute to improving teacher performance and learning quality. This study is expected to provide valuable insights for educational policymakers in designing more effective and sustainable teacher development programs.

Abstract

Warehouse operations are increasingly required to deliver high levels of accuracy, speed, and real-time visibility in response to growing supply chain complexity and customer expectations. However, conventional barcode-based warehouse management systems remain constrained by line-of-sight scanning, sequential data capture, and heavy reliance on manual intervention, which often lead to inventory inaccuracies and operational inefficiencies. This study investigates the implementation of Radio Frequency Identification (RFID) technology integrated with a Warehouse Management System (WMS) to enhance inventory accuracy and operational performance in warehouse environments. Using a case-based experimental research design, the study compares warehouse performance before and after RFID implementation across key processes, including receiving, storage, picking, and shipping. Operational data were collected through time studies, inventory audits, and error tracking under comparable workload conditions. The results demonstrate that RFID integration significantly improves overall inventory accuracy, reduces processing time by more than half, and decreases operational error rates by approximately eighty percent compared to a conventional barcode-based system. These improvements are primarily driven by automatic, non-line-of-sight, and simultaneous data capture enabled by RFID, which minimizes human intervention and ensures real-time synchronization between physical goods movement and digital inventory records. This research contributes empirical system-level evidence on the performance impact of RFID-enabled warehousing and proposes an integrated RFID–WMS implementation framework that supports end-to-end warehouse operations. The findings provide both theoretical insights and practical guidance for organizations seeking to adopt RFID as a foundation for smart warehouse transformation.

Abstract

This study aims to analyze the effect of leadership style and work motivation on the performance of truck drivers at PT Manggala Kiat Ananda, East Java area. A quantitative approach with a survey method was employed. Data were collected through questionnaires distributed to truck drivers as respondents and analyzed using multiple linear regression analysis. The results indicate that partially, leadership style has a positive and significant effect on truck drivers’ performance. Meanwhile, work motivation does not have a significant partial effect on performance. However, simultaneously, leadership style and work motivation significantly influence truck drivers’ performance. These findings suggest that drivers’ performance is more strongly influenced by structural and leadership factors than by individual motivational aspects alone. In a work environment characterized by standardized procedures and strict operational regulations, effective leadership plays a crucial role in enhancing discipline, responsibility, and work compliance. This study implies that transportation companies should strengthen operational leadership capacity and manage work motivation in an integrated manner to sustain performance improvement.

Abstract

This study aims to analyze the constraints of Beaching maneuvering on board LCT Sanjaya 01 and the efforts to overcome them. The research employed a descriptive qualitative method. Data were collected through interviews, observations, documentation, and literature review. The data were analyzed through data reduction, data presentation, and conclusion drawing. The findings show that the constraints of Beaching maneuvering are influenced by internal and external factors. Internal factors include the crew’s lack of readiness in preparing the required equipment, limited knowledge of Beaching procedures, inadequate maintenance of equipment such as the winch , ramp door, and wire rope, and weak coordination between the deck crew and the engine crew. External factors include weather conditions, currents, wind, waves, water depth, and the condition of the Beaching point. One incident that highlights the influence of external factors was the breaking of the forward mooring line during the Beaching process at Jetty Suaran due to strong river currents, heavy rain, and strong winds. Efforts to address these constraints include improving crew knowledge, conducting routine equipment maintenance, strengthening coordination among crew members, and carefully considering weather and water conditions before carrying out Beaching operations. The success of Beaching maneuvering is determined by technical readiness, crew competence, and accurate environmental assessment.

Abstract

The reliability of a diesel generator is essential to ensure a continuous electrical power supply and support ship operations. A decrease in cylinder compression pressure may lead to incomplete combustion, reduced engine efficiency, and increased operational failures. This study aims to analyze the factors causing compression leakage in cylinder number 3 of Diesel Generator No. 1 on KM Armada Segara, identify its effects on engine performance, and determine appropriate corrective actions. This research employed a descriptive qualitative approach using a case study method. Data were collected through field observations, interviews with engine room personnel, documentation, and inspection of engine components, and were analyzed using data reduction, data display, and conclusion drawing techniques. The results indicate that the compression leakage was caused by worn piston rings, damaged exhaust valves, and worn valve seats, resulting in a compression pressure decrease to 18 MPa compared with the normal range of 22–24 MPa in the other cylinders. This condition reduced combustion efficiency and negatively affected diesel generator performance. The study concludes that periodic inspection and timely replacement of components exceeding allowable wear limits are essential to maintain the reliability and operational performance of diesel generators.

Abstract

This study aims to analyze the causes of increased oil content in the effluent discharged from the Oily Water Separator (OWS) process, determine the resulting impacts, and formulate effective preventive and corrective measures. The research was conducted onboard MV. MERATUS PROJECT TANGGUH using a descriptive qualitative method, with data gathered through observation, interviews, and documentation from the daily logbook. The results indicate that the oil content in the discharged water exceeded the standard limit of 15 ppm on several occasions, reaching a peak value of 20 ppm. This increase was driven by technical factors, such as coalescer filter clogging and Oil Content Meter (OCM) inaccuracies; operational factors, including non-compliance with Standard Operating Procedures (SOPs); and maintenance factors, specifically the lack of routine servicing. The resulting impacts include marine environmental pollution, violations of MARPOL Annex I regulations, and a decline in OWS system performance as well as ship operational efficiency. Preventive measures that can be implemented include regular cleaning and component replacement, disciplined adherence to SOPs, and the execution of scheduled preventive maintenance. Based on the findings, it is concluded that the rise in oil content within the OWS system is a result of interacting multifaceted factors; therefore, mitigation must be addressed comprehensively through technical, operational, and maintenance approaches.

Abstract

This study aimed to analyze the effect of seafarers’ skills training programs on the performance of seafarers aboard merchant ships and to identify the factors contributing most significantly to training effectiveness. A quantitative method with a causal approach was employed, involving 72 seafarers working on merchant ships. Data were collected through Likert-scale questionnaires and analyzed using validity and reliability tests, classical assumption tests, simple linear regression, the coefficient of determination, and hypothesis testing with IBM SPSS. The results showed that seafarers’ skills training has a positive and significant effect on seafarers’ performance, as demonstrated by a calculated t-value of 11.373 and a significance value of 0.000 (< 0.05), confirming the acceptance of the research hypothesis. The correlation coefficient (R) of 0.806 indicates a very strong relationship, while the coefficient of determination (R Square) of 0.649 demonstrates that 64.9% of the variation in seafarers’ performance is explained by skills training, with the remaining 35.1% attributed to other factors. The findings indicate that training effectiveness is influenced by the training model, methods, instructor competence, relevance of training materials, and availability of facilities and infrastructure. Therefore, seafarers’ skills training is essential for improving competence and performance. Maritime education and training institutions, shipping companies, and government authorities should continuously improve training quality through competency-based curricula, instructor development, and modern simulation technology aligned with international maritime safety standards.

Abstract

Failure of the purification process in Fuel Oil Purifier No. 2 reduces the quality of fuel supplied to the main engine, resulting in incomplete combustion, lower engine efficiency, and increased component wear. This study aims to identify the causes of purification failure, analyze its impact on fuel quality and main engine performance, and propose corrective and preventive measures. A descriptive qualitative method was used, with data collected through direct observation during sea practice (PRALA), interviews with engine officers and crew, documentation, and literature review. The results show that purification failure was caused by fuel heating temperatures below the normal operating range (80–85°C) due to carbon deposits on the boiler burner, sludge accumulation causing bowl disc overflow, and damaged electric motor bearings and V-belts that prevented the purifier from reaching its optimum rotational speed. These conditions reduced the effectiveness of separating water and impurities from the fuel, allowing contaminated fuel to enter the main engine. As a result, combustion became incomplete, engine efficiency declined, and the risk of engine component wear increased. The study concludes that successful fuel purification depends on maintaining the correct operating temperature, ensuring the reliability of purifier components, and implementing proper maintenance procedures. Preventive measures include consistent application of the Planned Maintenance System (PMS), routine cleaning of the boiler burner and bowl disc, regular monitoring of operating temperature, timely replacement of worn bearings and V-belts with manufacturer-approved spare parts, and continuous monitoring of fuel quality to ensure reliable main engine performance.

Abstract

This study analyzes the clearance in and clearance out processes to reduce delays of vessels operated by PT Matsuura Indonesia Jaya at Gresik Port. Vessel arrival and departure services depend on document readiness, data accuracy, verification by relevant authorities, digital systems, and operational coordination. A descriptive qualitative method was employed through observation, semi-structured interviews with two operational officers, documentation, and analysis of 51 vessel-call records over 17 weeks. The results show that clearance in begins with receipt of the estimated time of arrival, document checking, system submission, verification, and issuance of service permission. Clearance out includes preparing departure documents before operations are completed, final verification, issuance of the Sailing Approval, and coordination of pilotage, towage, and unberthing. The stages requiring the greatest optimization are preliminary document checking, earlier submission, verification monitoring, and synchronization of administrative work with operational activities. Dominant controllable causes of delay include incomplete or expired documents, discrepancies between manual and system data, revisions or repeated data entry, delayed information, and slow coordination. Operational and external factors, including cargo-handling delays, technical readiness of vessels, service queues, network or system disruptions, weather, and sea currents, also extend waiting time. Optimization is achieved through document checklists, clear task allocation, early submission, status monitoring, and active communication among the parties involved.
