Generators are an important component in electrical generation. One of the disturbances that occurs in the generator is a short circuit fault. PT Oki Pulp and Paper has a Diesel Generator which is equipment that can be used as an alternative electrical generator to meet backup electricity needs, when a trip / shutdown occurs, the diesel generator will become backup power. The diesel generator observed is YCSR with a capacity of 3875 KVA/380 Volts. The purpose of this research is to analyse the Short Circuit Disturbance of Diesel Generator YCSR 3875 KVA and analyse the calculation of the time required for Over Current Protection on short circuit disturbance of Diesel Generator YCSR 3875 KVA. The research was conducted at the DG House of PT Oki Pulp and Paper in December 2024. The results of the short circuit fault analysis obtained are 17,042.40 A. The time required for the relay to disconnect the electricity during a short circuit is 4.09 seconds. The time obtained from the calculation is quite short, it can be seen that the short circuit fault that occurred was 17,042.40 A. To get the results of the relay working time, there is a calculation to find out how much TMS is determined through calculation, from the calculation getting the TMS result of 1,007 seconds. With TMS = 1.007 seconds, calculations are carried out to find the time required for the overcurrent relay to send a signal to the circuit breaker.

The need for electrical energy is increasing, especially in rural areas, so building an environmentally friendly energy power plant such as a micro hydro generator can be used to produce electrical energy. This PLTMH planning aims to help the community produce environmentally friendly electrical energy and overcome frequent power outages. The research discusses determining the type of turbine, water discharge, turbine power and generator power at (PLTMH). The water discharge (Q) value of 2.67 m3/sec is the water discharge during the rainy season. From the calculation results, it can generate 25.65 kW of electrical energy, the type of turbine used is an open flume propeller type turbine, the planning of a micro-hydro power plant with a turbine power capacity of 60 kW and a generator of 50 kW greatly influences the power that will be produced by the turbine, which This means that the greater the water discharge, the greater the power generated by the turbine, conversely, if the water discharge is small, the power produced by the turbine is relatively small.

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.

Socialization is a general concept which is defined as a process in which we learn to interact with other people, how to act, think and feel, all of which are important in producing effective social participation. This socialization was carried out as a form of the university's efforts to provide information regarding the acceptance of new students. The method used in this community service activity is providing socialization and promotion of all admission routes and study programs at PGRI Palembang University. In this socialization program, information is also provided regarding the new rules for accepting new students through the report card and written selectionroute. in 2024. With this activity, it is hoped that it will be useful for high school students in South Sumatra to be able to choose a major that suits their talents and interests. Apart from socialization activities, introducing the PGRI Palembang University Campus to high school and vocational school students in Ogan Regency Komering Ilir Palembang in this activity also socialized all majors, both undergraduate and postgraduate, for teachers who taught at the high school. As one university, PGRI Palembang University also holds socialization for new student admissions every year. 

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.
