Abstract

Fuel serves as a crucial element in the operations of fishing businesses employing boats. Presently, the usage of fuel in ships remains significant, yet it lacks thorough mathematical and theoretical assessment. This research aims to evaluate, both mathematically and theoretically, the fuel consumption of fishing vessels during their fishing endeavors. The study involved observations of various aspects, such as engine types, fuel types, and fuel flow, on fishing vessels. Fuel consumption was computed based on operational hours and RPM (Revolutions Per Minute) of diesel engines onboard ships. The findings revealed that engines with identical loads exhibited varying fuel consumption rates due to differences in cylinder volume. Additionally, fuel consumption increased with higher RPM. Fluctuations in fuel consumption during fishing operations were attributed to adjustments made by vessels according to environmental and situational factors. Theoretical and mathematical analyses indicated that several factors, including operational hours, RPM, and cylinder volume, influence fuel consumption in diesel engines of fishing vessels. This study's significance lies in providing insights into the theoretical and mathematical aspects of predicting fuel consumption in diesel engines utilized in fishing vessels.

Abstract

Refrigeration machines in fishery companies are widely used to maintain the quality of seafood products to keep them fresh. These machines are quite complex, so operating them correctly is crucial, as fatal operational errors can lead to the damage of the refrigeration equipment. The absence of written SOPs has the potential for non-standardized operations. Therefore, this article aims to develop Standard Operating Procedures (SOPs) for operating refrigeration machines on fishing vessels. To achieve this goal, data from the refrigeration system is used, and competent machine crew members are involved to obtain valid data. The data obtained is analyzed using a quantitative descriptive method. A proposed design of Standard Operating Procedure (SOP) with a cross-functional flow chart diagram has been produced as a guideline for operating refrigeration machines on fishing vessels. Based on the analysis, this SOP Draft has met the eligibility criteria for use. The SOP this machinery are highly significant in assisting the machine crew in ensuring that the machines are operated in a controlled manner following the correct procedures.

Abstract

Numerous studies have been conducted on voltage and current imbalance in three-phase electrical installations, but there has been no research specifically analyzing the correlation between voltage and current imbalances in the electric generators of fishing vessels. This study aims to investigate and analyze potential relationships among four key variables within this research context: apparent power, generator loading percentage, voltage imbalance, and current imbalance aboard KM. Sumber Mandiri.The research findings reveal the Pearson correlation coefficient value indicating the average generator loading percentage's correlation with the average current imbalance to be only 2.47%. Additionally, the average apparent power's Pearson correlation coefficient with the average current imbalance on the KM. Sumber Mandiri generator between November 17, 2022, and November 26, 2022, is calculated to be 0.29%. Moreover, the average generator loading percentage's Pearson correlation coefficient with the average voltage imbalance stands at 27.58%, while the average apparent power's Pearson correlation coefficient with the average voltage imbalance is at 40.91%. The fluctuations in current imbalance in relation to the variation in voltage imbalance on the KM. Sumber Mandiri generator show an impact of 14.03%, while the remaining 85.97% is attributed to other factors. The outcomes of this research are expected to provide valuable insights into the understanding of factors influencing voltage and current imbalance from a statistical perspective. Additionally, this study may assist in enhancing and designing more efficient and reliable electrical systems in three-phase installations aboard KM. Sumber Mandiri.

Abstract

The refrigeration system in the fishing process is important for maintaining the quality of the catch. However, the design of small-scale refrigeration machines is still not common, so it is an interesting study. Therefore, this study aimed to evaluate the design of small-scale fishing vessel refrigeration machines. Field studies are needed in machine manufacturing to observe the components required to match the refrigeration machine components onboard fishing vessels. This uses a direct observation method to determine the components of the refrigeration machine on the ship. Furthermore, the performance of the machines produced will be tested through the load cooling process. Parameters determined in the performance test include monitoring temperature (suction and discharge), pressure (suction and discharge), evaporator temperature, load temperature, COP (Coefficient of Performance), and compressor power. Refrigerant temperature measurement uses an insulative principle so that ambient temperature does not affect it. The result is that the machine produced has a capacity of 35 l or 15 kg of load. Meanwhile, in the performance test, the COP and electrical power generated while cooling the load for approximately 4 hours were 2,42 and 507 W, respectively. The results of this design were successful and did not experience failure. The significanceof this study can be used as a reference source for making cooling machines for storing the catch of small-scale fishermen.

Abstract

Monitoring of diesel engine operational performance on fishing vessels recorded in real time based on microcontrollers is still rarely used. Monitoring of diesel engine operations is important to ensure the engine is in optimal performance as well as a consideration for predictive maintenance actions. This study aims to design and implement a real-time monitoring device based on microcontrollers. This device can measure and record RPM, temperature, and pressure data on diesel engines with good accuracy. Hall effect sensors for RPM, DS18B20 for temperature, and piezoresistive sensors for pressure are used, to maintain the right time it is equipped with RTC, SD card module for data storage, and Wi-Fi module for data access via the web. The test results show that this device is able to measure with good accuracy on each parameter with an average error of below 2%. When the operational parameters exceed the predetermined threshold, the device successfully gives an alarm as a critical sign. This study makes a significant contribution to the management and maintenance of diesel engines with real-time data and wireless access that increases efficiency and minimizes downtime due to operational failures

Abstract

This study aims to calculate the cooling load required in Cold Storage to store fish catches. Cold Storage is an important facility in the fisheries industry to maintain the quality and freshness of the product. Accurate cooling load calculation is essential to design an efficient and energy-saving refrigeration system. The methodology used includes data collection on Cold Storage specifications, environmental conditions, and characteristics of the stored products. The cooling load is calculated by considering factors such as transmission loads through walls, roofs, and floors; product loads; air infiltration loads; internal loads from lights, equipment, and personnel; and other loads. The calculation results show that the total cooling load for Cold Storage with a certain capacity is 17.68 kW. Sensitivity analysis was conducted to evaluate the effect of various parameters on the cooling load. This study also provides recommendations for optimizing Cold Storage design and operational strategies to improve energy efficiency. The results of this study can be used as a reference in designing and operating Cold Storage for more effective and economical storage of fish catches.

Abstract

Although numerous studies have been conducted on voltage and current imbalance in electrical systems, research specifically focusing on these conditions in fishing vessels, particularly those operating in the Natuna Sea, remains very limited. This study aims to analyze the voltage and current imbalance on the generators of purse seine fishing vessels operating in the Natuna Sea, based on the IEEE Std 45-2002 and BKI Volume IV Year 2022 standards. A quantitative approach was employed, involving direct measurements of voltage (both line-to-line and phase-to-neutral) and current at the main distribution panels of five fishing vessels. The reference standard for Line Voltage Unbalance Tolerance (%LVUT) according to IEEE Std 45-2002 is ≤ 3%, while the acceptable limit for current imbalance according to BKI Volume IV Year 2022 is ≤ 15%. The results showed that the average voltage imbalance across the five vessels was below the IEEE tolerance limit (≤ 3%), with the highest recorded value being 4.34% on KM. Palembang Indah II. Meanwhile, current imbalance generally complied with the BKI limit (≤ 15%), except for KM. Rezeki Bersama, which exhibited the highest current imbalance at 30.48%. These findings highlight the need for mitigation measures, such as load redistribution and phase balancing, particularly on vessels with significant imbalance levels. This study provides practical contributions to improving the reliability of vessel electrical systems and enhancing operational safety within Indonesia’s marine fisheries sector.

Abstract

Although many studies have been conducted on the effectiveness of a generator or machine using the OEE (Overall Equipment Effectiveness) method, research focusing on the effectiveness of electrical generators on fishing vessels has been limited. This study aims not only to measure the effectiveness of the KM. Binama 03 generator but also to provide data-driven recommendations to enhance equipment reliability in the future. The study's results showed that the average values of Availability, Performance Efficiency, Rate of Quality, and Overall Equipment Effectiveness for the KM. Binama 03 generator in February, March, and July were 97.76%, 81.36%, 79.50%, and 63.49%, respectively. These figures indicate that the OEE values of the KM. Binama 03 generator during operations in these months were still below the JIPM (Japan Institute of Plant Maintenance) minimum standard of 85%. The findings of this research are expected to provide valuable insights for maximizing the effectiveness of equipment or machinery, as the primary goal of Total Productive Maintenance (TPM) is to ensure that machines remain in optimal condition without disrupting daily activities. This can only be achieved through preventive and predictive maintenance of the equipment.
