Abstract

In the coastal areas of East Java, especially in the Blimbing area, Paciran District, Lamongan Regency, most of the population works as fishermen who catch marine fish. One of the problems faced by fishermen is the use of ice cubes to preserve fish. However, ice cubes can reduce fish quality, melt easily, and are expensive. Also, it adds to the burden of the ship and increases the consumption of fuel oil (BBM). This socialisation programme aims to overcome these problems by introducing a cooling system that uses renewable energy through solar energy. This activity was carried out by presenting material and designing a solar cooling system on the boat. With this system, fishermen are expected to maintain good fish quality, increase production, and reduce operational costs, especially for fuel and ice, thereby increasing fishermen's income. This solar energy cooling system produces 1050 WP of power per day and has a battery capacity of 2400 Wh, and the ability to cool the freezer for an average of 12 hours per day.

Abstract

The design of a ship's propeller is very important as it directly affects the fuel efficiency, speed, and stability of the ship. Commonly, propellers are designed using expensive commercial software. This research aims to design a ship propeller using open-source code based on lifting line theory and using MATLAB application. The ship data used is a container ship with a length of 397 meters and a width of 56 meters. The propeller design results were propeller performance such as design performance, induced velocity, inflow angle, expanded blade, blade thickness, lift coefficient, performance curve, 2-D and 3-D outlines. A qualitative and quantitative comparison was conducted between a real-world manufactured propeller, a redesigned propeller developed using open-source software (OpenProp), and a commercial design tool (PropCAD). The comparison reveals that while the overall geometry and blade shape of all three propellers are similar, consisting of 6 blades with comparable radial profiles, key differences emerge in the expanded area ratio (EAR), skew angle, and surface modeling quality. The OpenProp design features an EAR of 1.0876 and a high skew angle of 39.9°, indicating an emphasis on hydrodynamic efficiency and cavitation mitigation. In contrast, the PropCAD model presents a slightly lower EAR of 1.077 with a more moderate skew angle of 20.5°, offering a balanced compromise between performance and manufacturability. This distinction highlights a potential optimization opportunity and demonstrates the capability of the open-source design approach to approximate real-world propeller characteristics with high fidelity, while also offering flexibility for further refinement. In summary, the findings suggest that the open-source design approach can approximate real-world propeller characteristics with high fidelity and provide flexibility for iterative optimization.

Abstract

In this paper an attempt has been made to assess how effective waste-collecting use catamaran ship with conveyor in the front. Numerical investigation based on Reynolds Averaged Navier Stokes (RANS) for predicting the flow pattern characteristics, velocity contour, and ship resistance. The focus of the present study is the impact of catamaran ship hull front shape on waste collection in calm water through the numerical methods. The three variations of the front of the hull used are symmetrical hull type, inner flat, and outer flat. It is done using speed variations of 1 to 4 knots. The results show inner flat hull catamaran has the smallest total resistance value than others. In addition, analysis of the flow pattern in front of catamaran shows that outer flat hull catamaran is the easiest to make waste closer to conveyor. From analysis of velocity contours shows that outer flat hull catamaran also has fastest to make the waste close to conveyor.

Abstract

The needs of society related to the energy crisis require alternative energy that can replace fossil fuels, such as Ketapang seed biodiesel. Preparation of crude oil by maceration method and making biodiesel through esterification and transesterification process. The research will discuss the performance of diesel engines with biodiesel fuel and Ketapang seed biodiesel with the composition of B0, B10, B20, B30. The test uses a rotation variation of 1200 to 2000 RPM and a load of 1000 to 3000. From the test properties and performance test research, it can be seen that they are related to each other. Biodiesel obtained better performance compared to B10, B20, B30. The lowest Specific Fuel Oil Consumption value is found in biodiesel fuel, where based on the average calculation on the maximum Specific Fuel Oil Consumption graph, B0 fuel produces a lower Specific Fuel Oil Consumption value than B10, B20 and B30 fuels with a difference of 33,759 gr/kWh, 49,661 gr/kWh and 113,694 gr/kWh. In this research process, the results of diesel engine performance using Ketapang seed biodiesel proved to be worse than biodiesel.

Abstract

Al-Karimiyyah Islamic Boarding School in Sumenep faces problems in water supply. The female students are forced to use brackish well water for drinking because the availability of potable water is limited, while using the services of a gallon water provider is very expensive. The need for drinking water must be met on an ongoing basis given the large number of female students and staff living there. This training activity aims to increase knowledge and understanding of the use of the reverse osmosis method water purifier. As well as improving the quality of water so that it is suitable for drinking.  The reverse osmosis system will treat and filter water to neutralise taste, odour, and harmful substances, so that it becomes ready-to-drink water. The training method was carried out through workshops and training on the use of tools with reverse osmosis systems that use solar power sources for female students in Beraji Village.  This activity was carried out for three days in the hall of Al-Karimiyyah Islamic boarding school, Braji village, Gapura sub-district, Sumenep district, East Java.   The boarding school residents learnt how to install and maintain a filtration device with reverse osmosis technology to provide ready-to-drink water. The device is placed outdoors for easy access by female students. Solar panel technology is used as the main power source so that this tool is independent in terms of electricity and can be placed in any location. This training activity is also an alternative to providing drinking water that is suitable for consumption, so that it can save time and money. In addition, santriwati also get education about the importance of consuming clean water to avoid disease. Santriwati now have sustainable access to clean drinking water. The application of reverse osmosis technology with solar power not only increases the availability of clean water, but also becomes a solution to electricity scarcity.
