Pelanggan PLN dengan golongan tarif I-3 yang mana pelanggan jenis ini dikenai denda pemakaian kVARh apabila pf rata-rata kurang dari 0.85 selama sebulan. Untuk itu, PT. Beiersdorf Indonesia ini memasang kapasitor bank berkapasitas 600 kVAR / 400 V yang berfungsi untuk memperbaiki faktor daya (pf). Sejak bulan Januari – Mei 2015, PT. Beiersdorf Indonesia ini tidak perlu membayar denda kVARh karena pf rata-rata berada di atas 0.85. Namun, pada bulan Juni 2015 PT. Beiersdorf Indonesia ini mendapat tagihan pemakaian kVARh dan tagihan pemakaian kVARh juga muncul pada bulan-bulan berikutnya. Sedangkan beban yang digunakan (motor-motor) sama. Penelitian ini bertujuan untuk mengetahui apakah kapasitas kapasitor bank yang terpasang sudah sesuai kebutuhan daya reaktif beban atau belum. Selain itu juga untuk mengetahui apakah instalasi kapasitor bank sudah sesuai atau belum. Sehingga dengan pemilihan instalasi kapasitor bank yang tepat, diharapkan biaya pemakaian kVARh tidak tertagih. Berdasarkan hasil penelitian, diketahui bahwa kontaktor kapasitor mengalami kerusakan. Hal ini terjadi karena kontaktor terpasang adalah kontaktor biasa, bukan kontaktor khusus kapasitor. Kerusakan kontaktor ini menyebabkan kapasitor bank tidak bisa mengokmpensasi pf dan mengakibatkan timbulnya biaya pemakaian kVARh. Supaya kontaktor tidak rusak lagi, maka sebaiknya kontaktor yang digunakan merupakan kontaktor khusus kapasitor. PLN’s customers with I-3 price class. This customer must pay the kVARh usage if the average power factor is less than 0.85 in a month. For that, it installs 600 kVAR / 400 V capacitor bank to upgrade the low power factor. From January – May 2015, this industry didn’t need to pay the kVARh usage because the average pf was more than 0.85. However, in June 2015 it got the bill of kVARh usage and it also appeared in the following months. The purpose of this research is to find out if the rating of the installed capacitor bank is correct or not. Besides, it is to understand if the installation of the capacitor bank is correct or not. So, if the installation of the capacitor bank is appropriate, this industry doesn’t need to pay the kVARh usage. According to the research, the capacitor contactor is damaged. It occurs because the installed contactor is the common contactor, not the special contactor for the capacitor. It causes the capacitor bank can’t upgrade the pf and the bill of kVARh usage is appears. In order to prevent the contactor from breaking down again, a special contactor for the capacitor is better to use.

Energy audit is a technique for calculating Energy Consumption Intensity (IKE) and aims to determine the energy use profile of a building and seek efforts to increase energy efficiency without reducing the comfort level of the building. The analytical method used is to make observations at Waluyo Jati Hospital by measuring the building area and ensuring appropriate lighting. Based on the Initial Energy Audit (AEA) which has been calculated and measured, the value of the intensity of energy has not met the standard because it is below the IKE standard for hospitals, which is 32.90617486 kWh/m2 on account calculations and 31.51399876 kWh /m2 on measurements that have been made, while the hospital IKE standard is 380 kWh/m2. The lighting system in the building still does not meet the standard of lighting strength according to the Regulation of the Minister of Health of the Republic of Indonesia No. 7 of 2019 concerning hospital environmental health. And for the lighting system it is not optimal and efficient, where the power consumption before repair according to the calculation is 4343.04 kWh, while after repair it becomes 4181.76 kWh / month 4343.04 kWh. The way to make energy use more efficient is to utilize natural light from the sun and change lamps and install energy-saving stickers in every corner of the room in the Central Surgical Installation and Intensive Care building at Waluyo Jati Kraksaan Hospital

PT. PLN (Persero) ULP Batu, The Selecta feeder is one of the 7 feeders in the distribution system that supplies several areas in PT. PLN (Persero) ULP Batu. In the Selecta feeder themselves, the number of error that occurred from January to November 2020 was fourteen times, with details of one time temporary error and thirteen times permanent errors. Delegating a portion of the load from feeders which got error can have an impact on feeders which are working normally. This can cause a voltage drop on the feeder for maneuvering purposes so that the distribution of electric power becomes less than optimal and requires some other loads to be temporarily transferred to other feeders. Based on the problems that occur, it is necessary to analyze the maneuver to reduce the impact of disruption on The Selecta feeder and maintain the reliability value of the distribution system at PT. PLN (Persero) ULP Batu.

Mojosari is a customer area consisting of industrial customers and high power customers. Currently, the demand for electrical energy in the area is supported by the Mojoanyar Feeder, which is supplied by the Transformer I Pulling Substation I with a capacity of 30 MVA. The reconfiguration of the feeder was carried out for several reasons, one of which was the addition of power from an industrial customer in the Mojoanyar Feeder area of PT PLN (Persero) ULP Mojosari, namely PT Sinar Karya Duta Abadi (Arwana). If there is additional power, the additional load capacity also increases in a feeder. If the load capacity increases, the current flowing in the conductor also increases. It can be seen from the loading data in February 2021 that the maximum current flowing in the Mojoanyar Feeder during the day is 210 A, the maximum current flowing in the Mojoanyar Feeder at night is 215 A. And if there is a disturbance near the area, the Mojoanyar Feeder will not maneuver because the load is close to the maximum. Therefore, PT PLN (Persero) ULP Mojosari plans a reconfiguration of the feeder by transferring the burden of the Mojoanyar feeder.The analysis was carried out using the simulation program ETAP Power Station 12.6.0. and manual calculations according to standards. After being reconfigured, the Mojoanyar Feeder experienced a decrease in the value of the voltage drop from 8.78% to 7.86%. Mojoanyar feeders experienced a decrease in losses of 5.84% compared to before the reconfiguration of 10.4%

The low power factor in the electricity installation of Sumber Wendit 3 water pumping stations causes a bill of excess reactive energy usage or kVARh, so that the cost of using electricity becomes higher. The excess use of reactive energy can be compensated by additional investment in installing capacitor banks in the main distribution panel (MDP) Sumber Wendit 3 water pump station. Based on the data and problems, it is planned to install capacitor banks that meet the standards with a target of 0.90 and 0.95 lagging. From the results of the planning, we need 150 kVAR and 250 kVAR capacitors, with an investment value of Rp. 94,983,790 and - Rp. 120,781,210. After an investment feasibility test using the Payback Period (PP) method, it is known that for a 150 kVAR bank capacitors, the investment return is technically 2.88 months and economically is 4.01 and 3.17 months. For 250 kVAR bank capacitors, the return on investment is technically 3.66 months and economically 5.1 and 4.03 months. When compared with the economic life of the investment is 10 years, the investment of the bank capacitor installation project is very profitable and feasible to carry out.

From the research that has been done at the Blitar Square Shopping Center, it was found that the power factor value is still below the standard with an average value of 0.711. Therefore, it is necessary to improve the power factor by installing a capacitor bank. The calculation results show that global compensation requires 12 capacitor banks with a rating of 10.4 kVAR, while sectoral compensation on the chiller load panel requires 7 capacitor banks with a rating of 10.4 kVAR and the foodmart load panel requires a capacitor bank with a rating of 10. 4 kVAR is 6 pieces. In addition, the installation of a capacitor bank also results in an increase in the voltage value in the system, this voltage increase is still below the permissible standard of ± 5%. The simulation of installing a capacitor bank on global compensation can improve the power factor value from 72.99% to 96.97%, with a voltage increase of 0.479% from the initial value of 397 V to 398.9 V, and a decrease in the current value of 24.645% from the initial value. 330.7 A to 249.2 A. While the simulation of installing a capacitor bank in sectoral compensation can improve the power factor value from 72.99% to 93.57%, with a voltage increase of 0.401% from the initial value of 397 V to 398.6 V , and a decrease in the value of current by 21.593% from the initial value of 330.7 A to 258.1 A.
