Abstract

This research aims to analyze the use of SIMON TKBM, identify obstacles in its implementation, and evaluate its impact on the efficiency of loading and unloading activities at Tanjung Perak Port. A quantitative approach was used involving a population consisting of 1480 loading and unloading workers (TKBM) at the port. The research sample was calculated using the Slovin formula with a margin of error of 10%, resulting in a total of 90 representative respondents. Data was collected through a questionnaire with 17 statements and then analyzed using validity, reliability and multiple linear regression tests to identify the relationship between the use of SIMON TKBM, implementation obstacles and its impact on loading and unloading efficiency. Referring to the validity and reliability test results, it shows that all questionnaire items are valid and reliable (Cronbach's Alpha = 0.893). Multiple linear regression analysis shows that the System (X1) and User (X2) variables have a positive effect on Interaction (Y), with the largest contribution coming from the user factor (coefficient = 0.301; significance = 0.003). Meanwhile, the System variable has a low and insignificant influence (coefficient = 0.090; significance = 0.395), which indicates the existence of technical problems in the system. The multiple correlation coefficient value of 0.519 indicates a moderate relationship between the three variables. These findings conclude that the implementation of SIMON TKBM is quite effective in supporting loading and unloading activities, especially with active user support, although technical improvements and identification of other external factors that influence system effectiveness are still needed.

Abstract

This study aims to analyze the influence of service quality on user satisfaction in the process of Business Activity Notification (PMKU) at the KSOP Class III Talang Duku Office. The research is motivated by several on-site challenges, including users’ lack of understanding in completing documents, repeated submissions, system technical issues, and low awareness among companies regarding licensing obligations. This research employed a quantitative approach with data collected through questionnaires and direct observation during the Land Practice (PRADA) program. Based on the results of simple linear regression analysis, a regression coefficient of 0.175 was obtained with a significance value of 0.003, indicating a positive and significant influence of service quality on user satisfaction. The R Square value of 0.133 shows that 13.3% of the variation in user satisfaction can be explained by service quality, while the remaining 86.7% is influenced by other factors outside the model. The t-test results confirm that service quality has a partial effect on user satisfaction, and classical assumption tests indicate that the regression model meets the requirements of normality, linearity, and homoscedasticity. Based on these findings, it is recommended that service quality be improved through user education, the digitalization of technical guidelines, the optimization of the Inaportnet system, and the implementation of an early warning system, in order to make PMKU services more effective, efficient, and in line with user expectations.

Abstract

The Indonesian maritime sector is highly dependent on main engine performance, where lubricant oil (LO) cooler temperature affects exhaust gas stability. This study analyzes the causal relationship between LO cooler temperature (X) and main engine exhaust gas (Y) on MV Logindo Overcomer. Using a quantitative causal-comparative approach, data were collected from 10 purposively selected engine room crew members during 12 months of Sailing Practice through Likert scale questionnaires, observations, and engine logbooks. SPSS v.27 analysis showed descriptive statistics (X: mean=52.50; Y: mean=37.70), highly valid/reliable instruments (Cronbach's α >0.90), regression equation Y=8.423+0.558X, coefficient of determination 71.6%, and Spearman correlation r=0.894 (p=0.000). The results prove a very strong influence of LO cooler temperature on exhaust gas stability. The conclusion recommends regular cleaning of the LO cooler, replacement of accurate thermometers, real-time monitoring, and crew training to prevent combustion inefficiency and overheating, similar to the case of KM Pratiwi Raya

Abstract

Pendangkalan alur pelayaran akibat sedimentasi meningkatkan risiko keselamatan dan menghambat aktivitas ekonomi. Fenomena ini terlihat nyata di Alur Pelayaran Kali Perak, di mana laju pengendapan beberapa tahun terakhir belum ditangani melalui pengerukan rutin dan berdampak pada operasional galangan kapal di sepanjang alur. Penelitian ini bertujuan menilai dampak sedimentasi terhadap operasional galangan kapal. Pendekatan kuantitatif digunakan dengan bantuan SPSS; responden adalah pegawai PT Dumas Tanjung Perak Shipyard dan Galangan Pelni Surya. Analisis menggunakan regresi linier sederhana menghasilkan persamaan Y = 5,943 + 1,112X, yang menunjukkan pengaruh positif dan signifikan sedimentasi (X) terhadap gangguan/biaya operasional (Y). Secara empiris, dampak yang teridentifikasi meliputi berkurangnya jumlah serta ukuran kapal yang dapat melintas, peningkatan biaya operasional, dan keterlambatan karena menunggu kondisi pasang tertinggi. Temuan ini menegaskan urgensi pemeliharaan berkala (pengerukan) dan manajemen alur untuk menjaga kelancaran operasi galangan dan keselamatan pelayaran di Kali Perak.   Shoaling of navigation channels due to sedimentation increases safety risks and hampers economic activity. This issue is evident in the Kali Perak navigation channel, where accelerated deposition in recent years has not been addressed through routine dredging, affecting shipyard operations along the waterway. This study assesses the impact of sedimentation on shipyard operations. A quantitative approach using SPSS was employed; respondents were employees of PT Dumas Tanjung Perak Shipyard and Galangan Pelni Surya. Simple linear regression yielded the model Y = 5.943 + 1.112X, indicating a positive and statistically significant effect of sedimentation (X) on operational impacts/costs (Y). Empirically, the impacts include fewer and smaller vessels able to transit, increased operational costs, and delays while waiting for high-tide windows. These findings underscore the urgency of periodic maintenance dredging and channel management to sustain shipyard operations and navigational safety in Kali Perak.

Abstract

The hatch cover is a critical structural component of a general cargo vessel, designed to safeguard cargo from seawater ingress and maintain watertight integrity. This study evaluates the constraints affecting the execution of planned hatch cover maintenance aboard MV. Orient King. A qualitative single-case study design was employed over a 12-month onboard observation period. Data was collected through semi-structured interviews with three key deck personnel (Chief Officer, Bosun, and Able Seaman), structured operational observations, and a review of maintenance logs. Thematic analysis of the data revealed that maintenance compliance is fundamentally hindered by aggressive marine corrosion, a brittle supply chain causing 2-to-3-month lead times for critical spare parts (e.g., rubber packing, hydraulic hoses), and a dense operational tempo that routinely forces the deferral of scheduled Planned Maintenance System (PMS) tasks. Consequently, temporary repairs are frequently substituted for permanent solutions, elevating the risk of cargo damage. To mitigate these risks, this paper proposes a prioritized action plan, emphasizing strict adherence to the company's Safety Management System (Document No. JSP E41), optimized spare-part inventory control, and enhanced supervisory protocols.

Abstract

The integration of Artificial Intelligence (AI) technology has created new opportunities to enhance language learning, particularly in vocational education contexts such as Maritime English. This study investigated the implementation of AI-assisted communicative scenario-based learning and examined its effectiveness in improving maritime cadets’ English-speaking skills. A mixed-method research design was employed involving 50 fourth-semester cadets of the Deck Department (Teknologi Rekayasa Pengoperasian Kapal). Quantitative data were collected through pre-test and post-test speaking assessments and questionnaires, while qualitative data were obtained from interviews. AI-supported tools, including Google Speech-to-Text, ChatGPT, Automatic Speech Recognition (ASR) and Langotalk, were integrated into communicative maritime scenarios such as VHF communication, cargo handling communication, and safety drill communication. The findings revealed that cadets demonstrated highly positive perceptions toward AI-assisted learning, with an overall questionnaire mean score of 4.36 (87.2%). Speaking assessment results showed significant improvement across all speaking components, including fluency, pronunciation accuracy, vocabulary mastery, grammar usage, and communication effectiveness. The mean speaking score increased from 68.24 in the pre-test to 82.10 in the post-test. Furthermore, the paired sample t-test indicated a statistically significant difference between pre-test and post-test scores (t = 14.52, p = 0.000 < 0.05). Interview findings also showed that AI applications enhanced students’ confidence, engagement, autonomous learning, and communication practice. The study concludes that AI-assisted communicative scenario-based learning is an effective and innovative approach for improving Maritime English-speaking skills and preparing cadets for professional communication in the maritime industry.   Keywords¾ artificial intelligence; communicative scenario-based; maritime English

Abstract

Shallowing due to sedimentation in the Tanjung Perak Port Pool, Surabaya is one of the main challenges that affect shipping safety. This shallowing can reduce the depth of the pool, hinder ship maneuvering, and increase the risk of ships running aground, especially for large ships. Periodic dredging is a strategic solution to maintain the depth of the port pool according to shipping safety standards, in accordance with the International Safety of Life at Sea (SOLAS) regulations. This study aims to determine, analyze and find efforts from the obstacles faced in the implementation of dredging activities in the Tanjung Perak Port Pool, Surabaya towards shipping safety. The research method used by the author includes descriptive analysis with a quantitative approach, data obtained by the author from questionnaires, interviews and field observations. The results of the study indicate that the main obstacles in dredging in the Tanjung Perak Port Pool, Surabaya include high ship traffic that hinders the smooth running of work, delays in the arrival of the Trailing Suction Hopper Dredger (TSHD) type dredger, and technical problems with dredging equipment. These obstacles have an impact on the dredging work process and increase the risk of shipping safety. There is a significant relationship between the constraints of dredging activities and shipping safety in the Tanjung Perak Port Basin, Surabaya, as evidenced by questionnaire data. Therefore, a strategy is needed to reduce the impact, such as improving coordination between the Port Authority and the Vessel Traffic Service (VTS), optimizing the dredging schedule, and improving maintenance of dredging equipment. With the improvement efforts in the dredging system, it is hoped that shipping safety in the Tanjung Perak Port Basin, Surabaya can be maintained, so that dredging work continues to operate optimally and supports the smoothness of maritime traffic in the Tanjung Perak Port Basin, Surabaya.
