Abstract

An oscillating water column (OWC) is a type of power generation device that converts ocean wave energy into electrical energy. The motion of ocean waves forces air through the OWC column and drives a rotor connected to a generator to produce electricity. The Wells turbine is a typical kind of rotor for OWC system. The performance of the Wells turbine can be influence by various factor, such as its geometry. Over the time, various research have been conducted to enhance the Wells turbine design. This study aims to analyze the impact of blade profiles on an 8-bladed Wells turbine’s performance using the Computational Fluid Dynamics (CFD) method. A full-domain with multiple reference frame (MRF) approach is applied to represent the rotating flow of the turbine. The flow is solved using Reynold Average Navier-Stokes (RANS) solver accompanied by shear stress transport  turbulunce model to capture the boundary layer near the wall. In this study, some blade profiles including NACA 0012, NACA 0015, and NACA 0018, with chord lengths of 100 mm, 125 mm, and 150 mm, are examined. The results of this study reveal that the NACA 0018 blade profile with a 150 mm chord length improves the torque coefficient  by 36.28% and the power coefficient by 1.04% compared to other configurations.

Abstract

Medium voltage (MV) switchgear at 20 kV, known as Panel Hubung Bagi (PHB) 20 kV in Indonesia, is a critical component of the electrical power distribution system, containing fuses, switches, and power conductors. A failure in this switchgear could lead to system-wide malfunctions, with potential catastrophic consequences such as fires or explosions. To prevent such events, it is essential to perform regular and well-planned maintenance. This research aims to optimize the maintenance process for MV switchgear, focusing on reducing maintenance tasks and frequency without compromising system reliability. The study employs the Failure Mode and Effect Analysis (FMEA) methodology, refined to reduce unnecessary maintenance actions. A Systematic Literature Review (SLR) was also conducted to analyze previous research on FMEA applications in 20 kV MV switchgear maintenance. Traditionally, maintenance was guided by manufacturers' recommendations, experience, and technical judgment, resulting in 3554 man-hours (MH) of labor every two years. However, by applying the refined FMEA process, maintenance requirements were significantly reduced to just 212 MH over the same period. This reduction represents a cost saving of 1678%, while still ensuring that the reliability of the MV switchgear at 20 kV is maintained at a high level. These findings underscore the importance of adopting systematic maintenance approaches to improve operational efficiency and reduce costs in power distribution systems.

Abstract

A Traditionl Wooden ship in North Penajam Paser is built without initial calculation to predict the resistance that will occur based on the shape of the hull. The ship is built solely based on the main dimensions and the number of engines to be installed, without considering the optimal hull shape. The hull shape is an important component in supporting the hydrostatic performance of a ship. Planning the hull's shape affect the ship's resistance value and ultimately impacts the ship's engine power requirements. The purpose of this research is to obtain the resistance value of the existing ship and determine the hull shape with a lower resistance value through computer-based simulations. The computer simulation approach based Holtrop method is used to determine the position of the LCB point based on the hull shape. Then, it examine the effect of the LCB position on the ship’s resistance of the hull shape. The hull shape simulation was conducted without changing the ship’s main dimensions. The simulation result show that the position of the LCB on the existing hull shape is 8.514 m from the AP, with a ship resistance value is 7.4 kN. Meanwhile, the optimum hull shape was found when the location of the LCB point was moved 0.1 m forward from its initial position (model 4). The resistance value in Model 4 decreased by 3.8% compared to the initial resistance value. In addition to model 4, models 2 and 3 also reduced the ship's resistance value, with changes of 0.9% and 2.1%, respectively. Furthermore, this optimal hull shape can be developed in the next analysis stage, such as ship structure planning and other design analyses.

Abstract

Fiber Reinforced Plastic (FRP) material has been widely used as a ship construction alternative to wood. FRP has many advantages such as lightweight material, easy maintenance, weather resistance, economical price, and shorter production time. FRP ship production is weak from the waste factor produced, such as production residue during shipbuilding, ship molds, and FRP shipwrecks. FRP waste can impact the environment, economy, and human health. These impacts include soil pollution, microplastics, skin diseases, and human respiratory disorders. FRP material tends to be burned by many shipyards but still leaves waste in the form of dust. FRP material is difficult to decompose and takes a long time to melt. One strategic effort to minimize the impact of FRP is to recycle FRP. This study aims to reduce FRP waste by making composite boards from FRP waste. The method used was experimental, involving the making of 12 specimens and testing the density, MOR, and MOE. Based on the results of the density value test, the average value obtained follows the JIS A 5905-2003 reference. The MOR and MOE values for each specimen do not comply with the Indonesian Classification Bureau (BKI) standards. In the ANOVA test calculation, no significant differences were obtained for MOR and MOE.

Abstract

The objective of this research is to design a catamaran tourist ship that incorporates green technology. To achieve this, the main dimensions of the ship will be determined using the linear regression method, based on existing data from similar vessels. The empirical data from existing vessels serves as the foundation for the analysis and prediction, thereby enabling the identification of relationships and patterns between the key variables, including length, width, draft, displacement, and passenger capacity. The linear regression method offers several advantages, including simplicity, ease of interpretation, and efficiency in the use of resources. As a result, it is an effective tool for initial analysis before the application of more complex methods. The R2 value has an average result above 90 percent, so the data can be considered good and valid. The innovative aspect of the design of this tourist ship is the utilisation of data pertaining to existing vessels that have demonstrated optimal performance in their role as tourist ships. The use of existing data not only helps reduce the risk of errors in the design of new vessels but also ensures that the design is efficient and compliant with operational needs and safety regulations. This research confirms the importance of a data-driven approach in the design of environmentally friendly and efficient ships. In the context of ship design and operation, displacement represents a pivotal parameter in linear regression analysis. An understanding of the relationship between displacement and ship performance allows for more accurate predictions regarding speed, fuel consumption, stability, and draft. This allows for the design of ships that are more efficient, stable, and safe, and optimized under a variety of operational conditions.

Abstract

Utilizing B30 as diesel fuel has the advantage of being heated to a specific temperature. Manually setting the temperature during the heating and fuel-filling process in the heating tank causes fuel performance to become less effective and efficient. This research aims to evaluate the capability of the prototype as a B30 fuel heater. The research method was carried out experimentally by testing variables for the temperature sensor (DS28B20), distance sensor (VL53LOX), heater control system, fuel filling system, and performance of the B30 diesel fuel heater prototype on a 7 HP single-cylinder diesel engine. The research results show that the fuel heater prototype can regulate the desired temperature and fill the heating tank automatically. The fuel temperature tested starts from 280C to 650C with an average multiple of 50C and tolerances of +20C and -10C. At the same time, it can automatically fill fuel from the main tank to the heating tank set from 800 ml to 1200 ml. B30 performance on a 7 HP single-cylinder diesel engine with 100 ml of fuel heated at 280C - 650C each shows the longest fuel consumption time at 350C and the fastest at 450C.

Abstract

Muara Angke Port, one of Indonesia's busiest fishing hubs, faces significant challenges due to dynamic water conditions and heavy vessel traffic, including waves, currents, tides, and vessel interactions. These conditions impact the motion response of fishing vessels, affecting their stability, maneuverability, and operational safety. This study aims to analyze the motion response of fishing vessels operating, focusing on environmental factors influencing vessel operations. A comprehensive analytical approach is employed, including the panel method for seakeeping analysis. Specific seakeeping criteria for fishing vessels, as proposed by Tello, are applied to assess vessel performance in various sea states. The findings indicate that fishing vessels can operate effectively in sea states with wave heights up to 3 meters, or sea state 5 and below. These results provide valuable insights into how fishing vessels respond to environmental challenges at Muara Angke Port, offering recommendations for improvements in vessel design. The study emphasizes the importance of developing operational strategies to reduce accidents and enhance the sustainability of the fishing sector, while supporting the long-term resilience of Indonesia's fisheries industry
