<![CDATA[Primary Shave Weight or often called roller is one component of the Continuously Variable Transmission system on the ESP 150 CC automatic motor which is often damaged, both wear and crack or break. Wear and tear is a phenomenon of loss of material from its surface to another or the movement of material on a surface or surface displacement with the passage of time over time this wear will cause damage to the roller rubbing against each other. To understand the life of roller components, it needs to be studied further. In the field of tribiology studies of the phenomenon of friction, wear on two objects that are in contact. This affects the life of a component, especially those that move in fast conditions with the level of loading, the process of wear due to contact becomes three parts, which include material, environment, operating conditions and geometry of the surface of the wear object. To quickly determine the condition of wear, a tribometer pin on disk test equipment is needed, this tool is used to test round roller components and Continuously Variable Transmission sliding roller ESP 150 CC, where the material is PTFE. The design of the surface contact mechanism in the radial direction so that the disk can rotate and this test equipment is given a speed of 1000, 2000, 3000 Rpm with of loading of 3 kg. Tests are carried out experimentally to determine the occurrence of wear, from the initial conditions to continuous conditions. The results show that the tribometer pin on disk test equipment is feasible to use to determine the damage parameters that occur. By looking at the weight of the roller that is reduced due to friction]]>

<![CDATA[Aluminum and its alloys are non-ferrous metals which are widely used in the shipping industry because aluminum is a lightweight metal, has a relatively high tensile strength and good corrosion resistance. Friction-stir Welding (FSW) is a welding that is widely used on thin aluminum plates. The heat input of the FSW welding is affected by the degree of tilt of the head tool to the material. This study aims to determine the optimal degree of slope in FSW welding. The parameters used in this study are 1500 rpm rotational speed, 1.33 mm / s welding speed with the same material thickness of 4mm and the type of connection used by lap joint refers to the AWS standard. In this study, the tool head tilt variation is 0o, 1o, 2o and 3o and the effect on the welding results. The results of the study show that welding with a slope angle of 0 ° and 1 shows visible defects or undercut defects caused by overheating when welding. The results of welding with a degree of slope 2 show the results of welding is good at the beginning of welding, but in the middle of welding visible defect undercut. Tilt angle welding shows the best results with no visible defects due to welding. The results showed that visually the results of welding with a slope angle 3 degree had the best results. This was due to the heat input on the welding with the head tool tilt not excessive so there was no visual defect.]]>

<![CDATA[This research was conducted to determine the electrical energy generated from friction heat in the braking process of disc brakes on four-wheeled vehicles with a calculation analysis of heat flow rates at speeds of 10 km/h and 15 km/h at 519 rpm, 748 rpm, and 1.234 rpm. The testing time is 20 minutes to get a measure of the heat generated from braking friction. The heat produced is converted into electrical energy using a thermoelectric device. Based on the calculation of the heat flow rate caused by friction on braking, a heat flow rate of 141.61 Watt is obtained and the voltage result is 317.2 mV. These results indicate the longer the braking is done, the heat generated from the friction force, the rate of heat flow flowing from the disk to the thermoelectric device, and the voltage result will be greater.]]>

<![CDATA[The energy crisis has become a global issue that must be resolved immediately through the use of new and renewable energy sources. Indonesia is geographically benefited because it is on the equator so that it gets a supply of sun throughout the year. This advantage is an added value for the application of solar-based energy systems. Concentrated Solar Power (CSP) system is an energy system based on solar thermal energy to generate electricity. The parabolic dish model in CSP has been shown to have the highest efficiency of up to 32%. The fundamental challenge of improving performance on the parabolic dish model is the design of the cavity receiver used. Cavity receiver functions to absorb heat from the reflector and distribute it to the system through the working fluid (Heat Transfer Fluid). This article specifically discusses the simulation of conical cavity receivers with a focus on the effect of pitch and fluid flow velocity in the system through Computational Fluid Dynamic (CFD) ANSYS. Simulation results on nine different variables show the effect of pitch and flow velocity on the overall transfer coefficient on cavity. The results of this simulation can be used as a basic reference in an effort to improve the heat transfer performance of cavity, which in turn can affect the overall performance of a Concentrated Solar Power Parabolic Dish type system.]]>

<![CDATA[This research was conducted by analyzing and optimizing the design of solar power plants with pumped storage systems as a source of renewable energy for remote areas in Indonesia. This research is very important to be done to solve the problem of meeting the electricity needs, especially in remote areas. The scheme is implementing 5 options in the pumped storage system. The system design is calculated and analyzed then optimization is done using Ansys fluent software. After that, all options are analyzed and compared in terms of economics related to Life-Cycle Cost (LCC) and Break Event Point (BEP) to get the best scheme. It was found that option A is better than other options in terms of system implementation because it requires the smallest number of pumps. From an economic standpoint, the LCC for option A is 63% lower than option C and higher than option B, D and E which are 2%, 5% and 25%, respectively. The lowest LCC is obtained by option E but has its own challenges in its application because it requires 540 pumps. The fastest BEP is obtained by option A with 9.47 years followed by an option D with 9.6 years. The longest BEP with 12.74 years was obtained by an Option C. Therefore, the use of pumped storage systems in solar power plants as an alternative renewable energy provides opportunities that are technically very possible and have the potential for continuous power supply in remote areas.]]>
