Abstract

Indonesia as one of the biggest capitals with fisheries industry have more than 90% small-scale fisher spread around the nation. Sadly, in some region, small scale fishers not really implement the proper fish storing method due to the lack of space in their vessel and limited technology. This issue has led to a new idea to build a portable cooling fish storage specifically for small scale fisheries. The aim of this studies is to build and test the performance of prototype of portable fish storage. The method used is direct testing by doing several tests such as power consumption test, temperature decreasing rate, and cost simulation efficiently with some condition and variables. The performance test resulted that power consumption of portable refrigerated fish storage around 374,94 - 651,93 watt with temperature decreasing rate of 0,5 C/minutes. In cost simulation, the portable refrigerated can save up to 90% rather than a traditional fish storage.

Abstract

This research aims to serve as a guidebook or framework for designing a general cargo ship, approximately 100 meters in length, by replacing the conventional diesel system with hydrogen and fuel cell technology. The reference vessel for this study is the general cargo ship with about 100m length operated in Baltic Sea. The results of this research provide the foundational calculations for designing a ship powered by hydrogen fuel cells, including the selection of hydrogen type, battery choice, and compliance with class standards. Additionally, the transformation of the ship's layout is a key outcome of this study. Based on the calculations, the ship, with a sailing duration of approximately three days, requires around 2800 kg of liquid hydrogen. This hydrogen supply can support 4 x 200 kW fuel cells and 5 x 70 kWh batteries. Ultimately, this allows for the design of a hydrogen-powered ship with an endurance of three days.

Abstract

Indonesia is one of the countries with the largest archipelagos in the world, boasting an abundant wealth of natural biodiversity. One of these resources is fisheries. The production of dried fish is one of the community's efforts to increase the selling price of fish. The dried fish produced by the community is usually sold in traditional markets and has few buyers due to the lack of attention to the quality of the dried fish. To increase buyers' interest in dried fish, the quality must be improved. The aim of this study is to enhance the production system and quality of dried fish through the use of drying equipment with different drying methods, namely natural convection and forced convection drying systems. In natural convection, the drying process utilizes the movement of air flows caused by density differences, while in forced convection drying, the air flow rate is controlled with the help of a fan. This study involves the use of four variations of air velocity that will be tested: 1 m/s, 2 m/s, 3 m/s, and a gradual reduction from an initial speed of 3 m/s, decreasing by 1 m/s every 3 hours of drying until reaching 1 m/s. Drying is then continued at an air flow rate of 1 m/s until the desired moisture content is achieved. The results of the study indicate that the use of natural convection and forced convection drying methods affects the drying rate and the final product quality, including color, texture, and taste. From the results obtained, the use of forced convection drying method with a gradual reduction in air velocity proved to be the best treatment, with a drying rate of 0.036 kg/h, yielding the best final quality in terms of color, texture, and taste.

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.
