Abstract

Triboelectric Nanogenerator (TENG) is an innovative technology that harnesses the triboelectrification phenomenon to generate electricity through the Contact Separation mode, where two materials with triboelectric properties interact. TENG can generate electricity at low frequencies. In the context of ship engine vibrations, the application of TENG with the Contact Separation mode can convert mechanical vibration energy from vibrations generated in the ship engine room into additional electrical power sources. The principle of TENG operation focuses on changes in triboelectric charge during the contact, separation, and compression processes. This study uses parameters commonly encountered in ships, namely low-frequency vibrations, as well as limitations imposed by classifications and regulations on these vibrations. Parameters used to analyze suitable modes for application in ships vary, namely frequencies ranging from 1 to 30 Hz and displacement distances ranging from 0.5 to 2 mm with intervals of 0.5 mm, resulting in voltages ranging from 0.01 to 1.55 V. After obtaining suitable modes, this study will match the modes for application on ships with a frequency of 50 Hz and displacement distances varied from 7 to 25 mm using FEP and Silicone materials, resulting in voltages ranging from 13.20 to 249.20 V. The results of this research can provide guidance for the development of TENG technology on ship engines to enhance energy efficiency and sustainability in the maritime sector.

Abstract

Vehicle ignition systems, including spark plugs, are a certain way to boost a motorcycle's performance. One kind of spark plug used to ignite the combustion process in a gasoline engine is a multi electrode spark plug, which has two or more ground points built into the electrodes. This study's overarching goal is to identify the optimal combination of multi-ground spark plugs, gasoline octane value fluctuations, and power/torque/specific fuel consumption parameters. Engine performance testing relies on data collected from controlled laboratory tests. In addition, Microsoft Excel is used for data analysis, and the results are shown in graph tables. Spark plug electrode amount in feet and gasolines octane level are the independent variables. Speed the engine from 5500 to 9000. The peak power output of 6.92 Hp was achieved at 7000 rpm in the power test with RON 92 gasoline X-Line spark plugs. At 5500 rpm, the maximum torque of 8.21 Nm was produced by the torque test using RON 98 gasoline X-Line spark plugs. At 6000 rpm, the specific fuel consumption test with RON 90 fuel and standard spark plugs yields a value of 0.0800 kg/Hp.hour.

Abstract

The development of technology in the 4.0 era has led to higher energy consumption. Meanwhile, Indonesia's energy consumption has been increasing every year. This requires the substitution of alternative energy vehicle fuels. One of them is bioethanol. Bioethanol can be obtained from plants, namely molasses. The use of RON enhancers can increase the octane rating so that low quality fuel can be used. By using high octane, the performance and fuel consumption will be optimal. The purpose of this study was to determine the performance of a 4-stroke petrol engine. This research uses an experimental approach where direct experiments are carried out on torque, power and fuel consumption. The data obtained is also presented graphically. In this study, the independent variables used were Ron enhancers with masses of 0ml, 5ml, 10ml, 15ml and molasses bioethanol percentages of 0%, 10%, 15%, 20%. Control variables engine speed 5500 rpm to 9000 rpm. The highest power results were obtained with a mixture of 0% bioethanol and 5ml RON enhancer, 7.90hp at 8000 rpm. The highest torque is achieved with a mixture of 0% bioethanol and 15ml RON enhancer 8.74 Nm at 6000 rpm. For fuel consumption, the 15% bioethanol mixture with the addition of 0ml RON enhancer is the lowest at 0.0804 kg/Hp.hour at 6000 rpm.

Abstract

The increasing complexity in ship construction due to larger vessel sizes has placed significant pressure on the shipbuilding industry to enhance efficiency and reduce costs. This paper focuses on optimizing shipyard facility layouts by minimizing material handling costs (MHC) and area costs (AC) using a topological approach for unequal areas. The objective is to develop a layout that reduces these costs while addressing gaps in previous research, which often assumed uniform department sizes. The proposed method employs the Non-Dominated Sorting Genetic Algorithm-II (NSGA-II), a heuristic algorithm designed for multi-objective optimization. Unlike previous models, this approach allows for variability in department sizes, aligning more closely with real-world conditions. The layout optimization is conducted by considering adjacency and non-adjacency constraints, ensuring an effective arrangement of shipyard departments. The results demonstrate that the proposed method significantly reduces both MHC and AC, leading to a more efficient and cost-effective shipyard layout. The dual-objective approach not only narrows the gap between topological and geometric models but also optimizes space utilization within the shipyard, making it a practical solution for modern shipbuilding challenges.

Abstract

Maritime tourism in Indonesia holds substantial potential for future growth, contributing to the well-being of coastal communities. Amphibious aircraft, capable of taking off and landing on both water and land, provide an efficient means for tourists to explore the country's diverse regions. Accurately predicting hydrodynamic loads is therefore essential to ensuring the reliability of amphibious float structures. This study aims to validate the feasibility of replacing cable-based accelerometer sensors with wireless alternatives to measure impact loads on an amphibious aircraft float model. Accelerometers were mounted on the float model, and impact loads were tested using a launcher in a mechanical workshop prior to hydrodynamic tests in a water tank. The data revealed that the sensors effectively captured impact loads, with measurements averaging a 3.7% deviation from theoretical values. The maximum impact force recorded was 1.98 g, and the minimum was 0.61 g. These findings support the use of wireless systems for hydrodynamic impact load testing in water tank environments.
