Abstract

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.

Abstract

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.

Abstract

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%.
