Abstract

The significance of ports in global trade activities has a significant impact on a city, region, and even a nation. A port with adequate facilities and a superior system will make port activities more effective, neutral, and even simple for its users. Inaportnet is a facility that is currently used by major Indonesian ports, including the port of Tanjung Emas in Semarang. The users of this system include exporters, importers, shipping lines, and others, in addition to port players. PT Global Logistic Agency is one of the user companies that has been using the Inaportnet framework. This study was descriptive research using a structured interview method. This study aims to examine the use of Inaportnet from the side of the organizer represented by PT. Global Logistics Agency. The results showed that the use of Inaportnet played an important role in the implementation of ship berthing services in terms of time efficiency, energy, and demurrage, the Inaportnet system is still found down or system errors are due to maintenance from the management unit so that PT. Global Logistic Agency must carry out conventional or manual implementation.

Abstract

The Covid-19 pandemic has fatal consequences for the world economy, one of which occurred in Indonesia. Government regulations require the public to apply health protocols that must be obeyed, namely social distancing which causes traders to be hampered in the process of buying and selling activities. The purpose of this study is to analyze the impact of Covid-19 on export-import activities in Indonesia. This research method uses the desk study method, namely the collection of data sourced from secondary data obtained from BPS in 2020. The results show that: Covid-19 has had an impact including: (1) The largest decline in the value of imports in Indonesia was experienced in February 2020 and May 2020; (2) Document processing must take longer due to this pandemic and all import-export activities must be guided by health protocols that must be carried out; (3) Delay in handling the ship at the port (ship delay), which will have an impact on the delay of the goods arriving at the hands of the owner of the goods (importer) which causes the importer to also have to prepare more costs for importing the goods.

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

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

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.
