<![CDATA[Stator Generator is a stator that uses a generator consisting of a coil and a magnet that emits an alternating voltage so that it can rotate the flywheel, the stator generator is a product of the development of the Stator Motor whose production demand is always increasing. The Stator Generator consists of Flywheel Assy and Stator Comp. In the Manufacture Stator Comp process, the longest production process is wire cutting. This research started from finding the problem of long production time. In the process of cutting wire, it is still done manually using cutting pliers by the production operator. To meet daily production needs, this wire cutting process requires two employees to carry out the production process with an ever-increasing target. From these problems, a wire cutting machine based on Automatic Wire Cutting was developed in order to get maximum and efficient production results. Calculations in material selection and cutter angle are also considered so that the results of the wire cutting process are stable and produce good cuts.]]>

<![CDATA[Design and manufacture of this simulator aims to explain how the movement of the differential components. The components of this differential simulation consist of a differential case, pinion gear or spider gear, side gear, spider shaft, electric motor, pulley, v-belt and dimmer (motor speed controller). The method used in making this simulator is to start by first making a simulator design and then continuing with the collection of tools and materials needed. From testing the components of the simulator tool which was carried out for 50 minutes, it was found that every 10 minutes the temperature increased due to the lubrication system that was not maximized. Tests to determine the correlation between the dimmer and the RPM of the electric motor, it was found that any decrease in the resistance value will result in an increase in the RPM value of the electric motor. These results also show that the maximum value of the motor RPM after being assembled is 1435 RPM. Then the test when given a load found that the shaft axle rotation speed of the differential will change if there is a load on one side. From this test, it can be seen that there is an increase in the RPM value on the side of the shaft axle which rotates freely when the other shaft is given a load. With this simulator, it can also provide an overview of how the movement of the differential gears contained in the axle of a unit vehicle so that you can understand how it works]]>

<![CDATA[Electrical energy is one of the most important daily needs for humans. Electricity is used to power tools that are used daily, such as turning on the lights, TV, refrigerator, and others. Electrical energy can be generated easily, there are already many power plants that can create electricity from new and renewable energy such as solar power plants (PLTS) and wind power plants (PLTB). The two generators can be combined to form a new system, namely the Hybrid system. In this study design a hybrid system of solar thermal energy and wind energy. The system formed uses a power storage system that is with a battery. Then the energy from the battery can provide energy to the load. The average power generated from the PLTS design is 0.474 Watt and the average wind generator is 9.378 Watt. Then the average hybrid system produces a power of 0.551 Watt. ]]>

<![CDATA[Crash box is one of the passive safety components in vehicles, especially cars that are designed to reduce the occurrence of injuries to drivers and passengers due to collisions. This study aims to determine the energy absorption of the crash box with a multi-segment circular cross section. The research method used is quasi-experimental, namely by computer simulation using Finite Element Method-based software. The independent variable in this study is the location of the segment connection, including: 1/4, 1/3, and 1/2 of the total length of the crash box. While the dependent variables that are sought include: energy absorption, force reaction, and deformation patterns that occur in the crash box. The crash box will be hit by an impactor with a mass of 103 kg and a speed of 7.67 m/s. From the simulation results, the maximum energy absorption and force reaction values are found in the crash box at connection 1/2 of 1689.7 J and 67718 N, followed by connection 1/3 with values of 1221.2 J and 56127 N, and the last is at 1/4 connection is 1119.8 J and 55443 N. Judging from the deformation pattern, the connection at 1/4 and 1/3 is buckling so that the energy absorption is lower than the crash box at the 1/2 connection. It is concluded that the most optimal design of the crash box with a multi-segment circular cross section is the model at the 1/2 connection because it has the highest energy absorption value of the other 2 models and the deformation tends to be more stable.]]>

<![CDATA[The alternator plays an important role in supplying the battery, lighting accessories and turning on the unit at the time of starting, therefore it needs more attention to it. Damage can occur at any time, and finding the problem with it presents its own challenges. Equipment such as a multimeter/avometer is needed to analyze the damage. Visual inspection, testing, and measurement are steps that must be taken to be able to find damage that occurs in the alternator. The charging system can be disrupted if there is an operational problem with the alternator component. This can be identified through an examination of the damage that occurred. Maintenance/maintenance on the components of the charging system must be carried out periodically so that the electricity supply remains optimal.]]>
