PLTMH is one of the renewable energy power plants that is environmentally friendly. Indonesia has considerable hydropower potential that can be developed into Micro / Mini Hydro Power Plants of 19,385 MW spread throughout Indonesia [2]. PicoHidro Power Plant is part of PLTMH with an output power of < 1 kW [1]. The advantages of this plant are generating electricity without being too influenced by seasons and day and night changes, power generation fluctuations are relatively small, the possibility of electricity generation is high, the impact on the environment is very small and the fast response is suitable for peak load conditions and when there is a disturbance in the network. PLPicohidro uses a DC generator that utilizes a power source for battery charging. The battery is used as an inverter voltage source to turn on the AC load. For that, a Charger Controller is needed which is useful for charging the battery. The DC voltage source coming from the generator is stored using a battery and then goes to the inverter to be converted into AC voltage. In this study, automatic charging of two batteries was used or can be called automatic charging. The way this circuit works is when the battery is full, the charger will automatically stop. The voltage indication during the charger process is 11 Volts and stops when the voltage reaches 14 volts. The use of two batteries in the charger process can work alternately, if battery 1 is full then battery 2 will charge automatically, and vice versa.

PT Pangkatan Indonesia is an oil palm plantation company operating in Labuhanbatu Regency, North Sumatra Province, with a plantation area of 7,134.8 ha and has built a palm oil mill with an installed capacity of 40 tons / hour. Liquid waste from the plant has the potential to be an alternative source of raw materials for Biogas Power Plants (PLTBg) which is also a distributed generation (DG). The parameters to be studied in this study are the decrease in power losses and the voltage profile of the electrical power produced. The simulation process produces voltage under normal conditions, which only increases about 0.3% of the nominal voltage (complies with Ministerial Regulation No. 4 of 2009). In addition, the results of interconnection analysis at the 1 MW PLTBG show that the voltage at the ends before and after the connection has increased. Furthermore, the ratio of the total current before and after (load 75% - 95% ) is fixed (no change). The conclusion of the results of this study is, the greater the load, the greater the power produced.

A distribution network is a conveyor network that connects the load center substation with the customer. The distribution network functions to distribute electrical energy to customers according to the power and voltage needed. The distribution network line from the Aurduri GI Transformer Bay goes to the incoming to be lowered voltage from 150kv to 20kv. After the voltage is lowered, it is directly channeled to the Jelutung Feeder to find out the daily load on the distribution network. The population in this study is "Study of Daily Burden on the Distribution Network of Jelutung Feeders". The highest daily load is the electrical load that occurs at the highest time in 24 hours. This can be affected by household, industrial, commercial activities and weather conditions. Daily peak loads occur at certain times such as the afternoon. The lowest daily load usually occurs in the morning around 06.00 to 07.30. Average lowest current (I) R,S,T 92,275A and lowest power (P) 3.29Mw. While the average highest current is 212.7A and the highest power is 7.54Mw. The highest current in September was on the 15th with a power of 8.0 mw at 18.30.

Construction design and electricity distribution planning cannot be separated from how the electricity distribution system is built. Moreover, electricity is an important factor in creating a just and prosperous society in all fields. This research analyzes the design of the 20 KV Medium Voltage Air Line (SUTM) in the Tanjung Kaasri Village location, Angkan District, Merangin Regency, Jambi Province, whether it is in accordance with the standards used by PLN (SPLN). The research method used is the method of observation and measurement in the field. The results of the research concluded that when calculating the mechanical force of the pole, a 12 meter, 200 daN iron pole and a 9 meter, 100 daN iron pole were chosen as the schor pole. Then the use of TM poles includes: TM-1 Number of 45 rods, TM-3 Number of 80 rods, TM-4 And the cable used is AAAC-S 150 mm with a total number of cables of 22,240 The calculation results and the realization in the field are almost close, the difference is only under 1%. By always carrying out evaluations on each project, this data can be used as input for project owners and implementers, so that the quality and reliability of the system can be met.

During the distribution of electric power, there are power losses which occur in both the line and the transformer. Power loss can be identified if the voltage at the transmitting base (generator) and the receiving base is different from research data. Power loss is energy loss that cannot be avoided. It is important to anticipate and examine energy loss in order to ensure it stays within acceptable boundaries. A lack of electricity supply in an area will result in low voltage, even power outages. The voltage and current at peak load every day are taken at 14.00 WIB and 22.00 WIB. The distance from the Aur Duri substation to the Payo route is 19 km, as this transmission line enters the short transmission line. The power losses that occur when sending power from G.I Aurduri to the Payo Selincah department are quite large. However, these losses still meet the requirements for the feasibility of transmission lines according to PUIL PT. PLN (Persero) 2010, namely not more than 10%. The cause of power loss is due to several factors, namely insulator leaks, long distances, environmental temperature, lack of current flowing and the conductor table material used.

PT PLN (Persero) ULP Telanaipura showed significant improvement in overcoming customer complaints. Customers can now report their complaints practically through the PLN Mobile application or direct visits to the nearest ULP office. This efficiency is driven by the Integrated Complaints and Complaints Application (APKT), a web-based internal system at PLN. APKT is designed to process all types of complaints and grievances received from call centers 123, ensuring prompt response and resolution as per the set time standards. Prior to the implementation of APKT, complaint management was still conventional, not integrated, and without real-time monitoring. The presence of APKT has eased the workload of PLN employees throughout Jambi City rayon, allowing for faster and easier resolution of customer complaints. This study focuses on the effectiveness of the APKT system in customer complaint management at PT PLN (Persero) ULP Telanaipura. If customers have complaints, they can contact the PLN 123 call center. The customer service operator will provide guidance and gather the necessary technical information. The most dominant interference that customers often complain about is interference with the code 99110 (approximately 3.93%), which is often associated with "clear tamper" and "voltage drop" issues. In contrast, the 99115 code disruption, i.e. complaints of misinformation with unidentified causes, is very rare, accounting for only about 0.16%.
