Abstract

The impact of the converter kit type on the performance of diesel engines using biodiesel and LPG fuel has been explored. Converter kits play a vital role in transforming the fuel supply system, and experiments have been conducted to assess their influence on various engine performance parameters. The findings of the study indicate that the selection of a converter kit significantly affects the performance of dual-fuel diesel engines (biodiesel and LPG). Gas Heater converter kits, including type 1, type 2, and type 3 variations, were scrutinized in this research. Testing revealed variations in LPG-Biodiesel fuel mixing ratios depending on the type of converter kit employed. For instance, Gas Heater type 3 achieves the highest value with a mixing ratio of 14.4. Furthermore, the performance of the engine in terms of power and torque is also impacted by the type of converter kit utilized. Gas Heater type 1 exhibits peak performance, with power reaching 5.4 kW and torque measuring 34.81 Nm. Despite the operational costs of dual-fuel diesel engines tending to be higher than those using pure biodiesel, the research concludes that the choice of the converter kit type can have a substantial effect on engine performance, particularly regarding fuel efficiency.

Abstract

This is The Stirling engine is one of the alternative power generators that can be implemented at this time. The power generated by the Stirling engine can be used as a generator of electrical energy or for automotive applications. This study aims to determine the optimum performance of the stirling engine in power and torque by providing variations in temperature. The test temperature was carried out by providing energy from LPG fuel with varying temperatures, namely 200˚C, 300˚C, 400˚C, 500˚C, 600˚C and 700˚C. The data taken is RPM, power and torque. From the test results, for 200˚C is 16 W, for 300˚C is 30.66 W, for 400˚C is 45.72 W, for 500˚C is 67.5 W, for 600˚C is 81.06 W, for 700˚C is 105.27 W. In this study, a variant of changing the weight of the flywheel was also carried out. The test results show that an increase in flywheel weight of 1 kg causes an increase in RPM of 22.7% and power of 22.7%.

Abstract

Maintenance on the turbine must always be carried out, because if one component of the turbine engine is damaged, it will affect the entire performance of the turbine engine. The function of bearing lubrication in turbines is to prevent direct contact between the bearing and the turbine shaft. Therefore, lubrication is needed. Bearing lubrication on the turbine is a very important issue so that the turbine should not be rotated without lubrication will cause material damage. Preventive maintenance of turbines can be pursued by implementing QCC PM. Adding a portable purifier when excessive water content occurs, adjusting the pressure steam seal serves to prevent main steam from entering the bearing area which can cause high water content due to mixing of oil with water. Making a steam block serves to prevent steam from entering the bearing area lubricated by VG 46 medium oil, causing high water content. And routine maintenance to check the mesh aims to assess the feasibility of the mesh and the suitability of the needs of the cleanliness purifier oil system which can be seen from the CBM data, namely tribology monitoring.

Abstract

This paper explores the concept of digitalization in critical sailing lines to manage ship-generated waves (SGW), with a focus on fishing boats. Indonesia, as a maritime nation, faces challenges due to the environmental impact of SGW, such as riverbank erosion, habitat disruption, and damage to marine infrastructure. The proposed digital framework integrates real-time environmental data, including tidal conditions, river currents, and water depth, with vessel parameters like speed and GPS tracking. This system aims to provide accessible information through websites and smartphone applications, enabling safer and more efficient navigation. The results highlight the importance of digitalization in enhancing maritime safety, reducing environmental damage, and improving operational efficiency for fishermen and port operators.

Abstract

Deflector Roll plays an essential role in the manufacturing of tinplate at PT Pelat Timah Nusantara (Latinusa), Tbk. This research examines the corrective maintenance procedure by employing the breakdown method to pinpoint repeated problems and their resolutions. The primary issues noted include degraded bearings, soiled surfaces, and uneven rollers, all of which hinder production continuity. The maintenance procedures consist of disassembling, examining, replacing, cleaning, balancing, and reassembling. Analyzing 55 documented damage occurrences from 2015 to 2024 reveals that surface-related problems were predominant, with 9 instances (16.36%) of glossy smooth surfaces, followed closely by surface buckling (14.55%) and dirty surfaces (14.55%). The outcome indicates that organized maintenance enhances efficiency and extends roll lifespan

Abstract

Karangantu Port, located in Banten Province, plays a strategic role in supporting capture fisheries activities. However, fishing vessels operating in this port often face hydrodynamic resistance issues that affect operational efficiency. This study aims to analyze the influence of vessel speed and draft on the total resistance experienced by fishing boats. A 3D hull model was developed using SolidWorks and simulated using Maxsurf. Speed variations ranged from 5 to 12 knots, with four draft levels tested: 0.5 m, 0.7 m, 0.9 m, and 1.1 m. The results show that total resistance increases significantly with speed, particularly due to the dominance of wave-making resistance at speeds above 8 knots. Deeper drafts also lead to higher frictional resistance, caused by the increased wetted surface area. The optimal operational speed for maintaining fuel efficiency is in the range of 6 to 9 knots, with a balanced draft setting to ensure vessel stability without excessive resistance. These findings are expected to contribute to more efficient design and operation of fishing vessels at Karangantu Port.
