Abstract

This study aims to evaluate how the condition of the cylinder block affects the fuel efficiency of a Mercury 450 Racing V8 speedboat engine. As a vital component in the engine, the cylinder block is responsible for housing and supporting the cylinders, where the combustion process takes place. Damage to the cylinder block, such as cracks, corrosion, or wear, can lead to decreased compression pressure and gas leakage, resulting in decreased combustion efficiency and increased fuel consumption. This study used an experimental approach to assess the effect of different levels of cylinder block damage on engine fuel efficiency. The results showed that the condition of the cylinder block significantly affects fuel efficiency, with damaged cylinder blocks drastically reducing engine efficiency. These findings highlight the importance of regular maintenance and repair of the cylinder block to maintain optimal fuel efficiency and improve speedboat engine performance. The repair of the cylinder block gave an improved fuel consumption efficiency of 22.22% meaning the engine became more efficient in using fuel after the repair of the problem of sticking shells and oil leakage.

Abstract

The development of electric vehicle charging station infrastructure in Indonesia is still slow, resulting in difficulties for electric vehicle users due to limited driving range. On the other hand, Indonesia has a target of net zero emissions by 2050, while most of the energy sources for electric vehicle charging stations still rely on fossil fuels. To address this issue, innovative solutions such as electric vehicle charging stations powered by renewable energy are needed. Wind turbines and solar panels are technologies that can be utilized as energy sources. Power plants with a single energy source like solar panels have limitations in their energy production time. While wind turbines can operate 24 hours, they depend on wind speed. To overcome this problem, the solution is to implement a hybrid system by combining both wind and solar energy sources and converting them into electrical energy. This research aims to investigate the performance of a wind-solar hybrid power plant for electric vehicle charging station applications. The wind-solar hybrid power plant in this study is designed to provide electrical energy for one unit of an electric motorcycle with a battery capacity of 72 Volts 20 Ah. This research uses an experimental method in a real environment. The wind turbine used in this study is a cross-flow type, while the solar panel used is monocrystalline. To find the optimal point of the hybrid power plant system in converting energy, the influence of the number of turbine blades and the tilt angle of the solar panel on efficiency is investigated. The results show that a turbine with 6 blades can produce higher efficiency compared to turbines with 4 and 5 blades. Meanwhile, a tilt angle of 15o can produce higher efficiency compared to tilt angles of 0o and 30o.

Abstract

This study aims to analyze the energy efficiency and capacity optimization of the TD 530 YML VK boiler after the occurrence of damage in the combustion system, specifically pipe leaks. The research was conducted by monitoring the boiler's condition before and after the leak, as well as after repairs were carried out. The methods used include collecting data on the leak, calculating energy efficiency, and evaluating fuel consumption. The results show that pipe leaks caused a 10% decrease in efficiency and an 11.1% increase in fuel consumption. After the repair, efficiency improved to 95% of the optimal condition, reducing fuel consumption by 5.31% for Diesel Oil and 5.26% for Natural Gas. The conclusion of this study is that repairs can enhance energy efficiency and reduce fuel consumption, although the performance does not fully return to the pre-leak optimal state
