The research issues include the performance of three-phase induction motors and the impact of load on three-phase induction motors. This study aims to develop a driving system for empty fruit bunches (EFB) processing machines using induction motors at PT. Suryabumi Agro Langgeng, South Sumatra. The research was conducted at PT. Suryabumi Agro Langgeng in South Sumatra, from May to June 2024. Primary data in this research were obtained through observation and interviews, while secondary data were gathered from document analysis. In the context of this research on three-phase induction motors, document analysis techniques can be used to analyze various documents such as scientific literature, technical specifications, maintenance reports, production records, or other documents related to induction motors. The research methods include system requirements analysis, system design and implementation of the driving system, and performance testing of the developed system. The results show that the use of induction motors can provide better operational efficiency in EFB processing. This research is expected to contribute positively to improving the efficiency and productivity of PT. Suryabumi Agro Langgeng's operations.

In evaluating street lighting systems, the main factors are safety, comfort, and beauty for road users who must receive special attention. Street lighting is very useful at night or during dark conditions such as rain or cloudiness. Therefore, the authors evaluate the street lamp lighting system on the street .A.Nakowi .No17.Rt14 in the village of KentenLaut. From the results obtained, the length of the road is 240 meters with a road width of 4 meters for the calculation of the installation of street lights based on the reality in the field by taking into account road conditions and road classification. The lamp used is SON-T 150W, after an evaluation, the street lamp lighting system on the street. A.Nakowi.No17..Rt14.In the village of KentenLaut does not meet the standards, so the street lamps in the village of KentenLaut must be repaired or replaced with lamps so that the lighting can match the standard of street lamp lighting, the standard of good street lamp lighting is 20 lux so that road users feel comfortable with bright lighting.

<p><em>The use of robotics to cut grass has been widely used to make it easier and reduce the risk of danger from being hit by cutting blades. Robotic lawn mowers can replace conventional lawn mowers in terms of efficiency and safety in use. In this research, a grass cutting robot will be designed, which will be controlled remotely using a remote control. The drive on the lawn mower robot uses a DC Gearbox motor for forward and reverse movement, a DC Servo motor for turning right and left, and a DC RS 755 motor for movement or to rotate the lawn mower blade. From the results of the tests that have been carried out, the driving performance of the grass cutting robot is in accordance with the design. For forward and reverse movement, the remote control can remotely control the DC Gearbox motor, and the robot lawn mower motor has forward and reverse movement. Where for the forward movement speed of step 1, the speed is 287 rpm - 489 rpm with a torque of 1.1651 Nm - 0.6838 Nm. For step 2 forward movement speed, the speed is 608 rpm - 1,200 rpm with a torque of 0.5500 Nm - 0.2787 Nm. Then for step 1 reverse movement speed, the speed is 432 rpm - 631 rpm with a torque of 0.7741 Nm - 0.5299 Nm. For step 2 reverse movement speed, the speed is 973 rpm - 1,071 rpm with a torque of 0.3437 Nm - 0.3122 Nm. Then for right and left turning movements, the remote control can remotely control the DC Servo motor, and the grass cutting robot has turned right and left. Where for the robot's turning movement to the right and left, step 1 at a speed of 287 rpm - 489 rpm gets a turning angle of 30° with a turning radius of 180°, and step 2 at a speed of 608 rpm - 1,200 rpm gets a turning angle of 20° with a turning radius. 180°. Furthermore, for the movement of the lawn mower blade, the remote control can remotely control the RS 755 DC motor, and the lawn mower blade on the robot rotates. Where for the step 1 grass cutter blade movement speed, the speed is 172 rpm - 229 rpm with a torque of 1.9442 Nm - 1.4602 Nm. For step 2 grass cutter blade movement speed, the speed obtained is 806 rpm - 918 rpm with a torque of 0.4149 Nm - 0.3643 Nm. For step 3 grass cutting blade movement speed, the speed is 976 rpm - 1,147 rpm with a torque of 0.3426 Nm - 0.2915 Nm.</em> </p><p> </p><p class="IndexTerms"><strong>Keywords</strong>: Mover, Robot, Lawn Mower.</p><p class="Abstract" align="center"><strong> </strong></p><p class="Abstract" align="center"><strong>ABSTRAK  </strong></p><p class="Abstract">Penggunaan robotika untuk memotong rumput sudah banyak dilakukan untuk memudahkan serta mengurangi resiko bahaya terkena pisau pemotong. Robot pemotong rumput dapat menggantikan mesin potong rumput konvensional dalam hal efisiensi serta keamanan dalam penggunaaan. Pada penelitian ini akan dirancang penggerak robot pemotong rumput, yang dikendalikan yang dikendalikan dari jarak jauh menggunakan remote control.
