<![CDATA[In the process of building a ship, electrical and lighting installation is one of the important components in the construction of a ship that concerns every room on the ship. This study conducted tests on the study of LED lights in the room above the ship. The method used is the zonal cavity method with division in one room into three parts, namely the height ceiling cavity (hcc), height room cavity (hrc), and height floor cavity (hfc) as well as determining the illumination value according to the standards set for each room. And the results obtained for the lamp power at TASA 22 by using the type of lighting with the LED type obtained a lighting electric load of 1.483 Kw. The results of this study provide for the fact that from various other research sources, it is concluded that LED lamps are better than TL lamps.]]>

<![CDATA[The growing public awareness of the environmental atmosphere has triggered a paradigm shift to design composite materials that are environmentally friendly and energy efficient. Composite materials made from natural fibers have been able to replace metal, steel, and wood because of their ease of use and features. Indonesia has a lot of natural fiber potential, one of which is rattan and bamboo fiber which has significant potential for composites. The use of bamboo and rattan fibers as reinforcement in composite materials has increased rapidly and has undergone a high-tech revolution in recent years in response to the increasing demand to develop biodegradable, sustainable and recyclable materials. In this research, a test made from natural fibers was carried out to find out whether the composite was suitable for use as a substitute for fiberglass on ship hulls. The results of the Tensile test for composites reinforced with natural fibers of bamboo and rattan fiber in the 90° fiber direction obtained the average value of the three experiments with a value of 67,41 Mpa and in the 45° fiber direction the average value of the three experiments was obtained with a value of 57,67 Mpa. The results of the bending test for composites reinforced with natural fibers of bamboo and rattan fiber in the 90° fiber direction obtained an average value of the three experiments with a value of 114,64 Mpa and Dan in the 45° fiber direction obtained an average value of the three experiments with a value of 129,93 Mpa.]]>

<![CDATA[Palm oil is the largest commodity in Indonesia. Pprocessing of oil palm, leaving 20% to 23% empty palm fruit bunches (EFB). Oil palm empty fruit bunches (EFB) is a collection of fiber left behind after separating the fruit from fresh fruit bunches that have been sterilized. Some researchers use natural fibers as an alternative for making composites. This study aims 1. To determine the tensile strength of the alternative material of palm empty fruit bunch fiber. 2. To determine the buckling or bending strength of the alternative fiber material for empty palm oil bunches. The method used is the tensile and bending test method in the process of mixing the fiber material of empty palm oil bunches in the manufacture of composites. The test results obtained were compared with the BKI composite standard. The volume fraction used in this study was 30% polyester resin and 70% EFB fiber, 40% polyester resin and 60% EFB fiber and 50% polyester resin and 50% EFB fiber with NaOH alkaline treatment for 2 hours. The average tensile stress values obtained for each fraction were 27.372 MPa, 24.168 MPa and 25.875 MPa respectively. The values for the bending stress of each fraction are 144.836 Mpa, 149.059 Mpa and 164.682 Mpa respectively.]]>

<![CDATA[Analysis of stresses and deformations in the Single Point Mooring (SPM) yoke structure using the Finite Element Method (FEM) aims to determine and understand the stress distribution and deformation of the yoke, so that offloading activities comply with safety standards. The finite element method is a numerical modeling technique used to predict the behavior of a system by dividing an object into a number of elements that can be analyzed independently. This study uses 3 geometric models, namely single point mooring yoke geometry aged 0, 20, and 30 years. The results of the analysis will assist in understanding the stresses and deformations that occur in the SPM yoke structure. To simulate the tension of the ship during unloading, tensions of 75, 100, and 125 tons are represented. For each geometry, the greatest stress and deformation values found are 89 MPa for the 0-year model, 89.2 MPa for the 20-year model, 97.1 MPa for the 30-year model, respectively, and 0.08 mm for the 0-year model, 0.10 mm for the 20-year model, 0.11 mm for the 30-year model. This investigation demonstrates that the observed stress levels and deformations comply with safety standards.]]>

<![CDATA[The speed on the ship is inseparable from a good propeller design in order to get the optimal thrust generated by the propeller motion. The propeller is a very important part in determining the ship's motion. The propeller itself is a tool used to generate thrust that comes from engine power transmitted through the shaft. Computational Fluid Dynamics (CFD) is a very suitable method for analyzing complex systems that are difficult to solve using manual calculations. With these advantages, CFD is often used to analyze a pattern of a system, one of which is the propeller, which in this study uses variations in flow velocity and propeller speed which can affect the value of the torque and power produced by the propeller.]]>

<![CDATA[The exhaust manifold, also known as the exhaust header, is an important channel in the combustion chamber of a car. The exhaust manifold's role is to collect exhaust gas from various exhaust channels and direct it to the catalyst and car exhaust muffler for filtering. This research was conducted to see the pressure loss in the exhaust manifold at different speed conditions and different inlet positions on an engine with 4 cylinders. The speed variations used were 0.4, 0.6 and 0.8 m/s while the inlet position variations used were 1 and 3 and 2 and 4. The method used was numerical simulation. Geometry is created in the CAD software, then proceed with creating a mesh and setting boundary conditions. The results obtained show that the greater the flow rate, the greater the pressure drop. Based on the inlet position, positions 2 and 4 tend to have a greater pressure drop than positions 1 and 3 at each of the same speed. The largest pressure drop is 1.5438 Pa at a speed of 0.8 m/s with inlet channels 2 and 4.]]>
