Quest Hotel Kuta is a place of business engaged in lodging services. To support operational needs, the hotel uses electrical equipment, most of which are inductive. The use of high inductive loads can produce high reactive power, depending on the power factor because the active power obtained from the installed power will be less. Based on the measurement results at Quest Hotel Kuta the measured power factor is 0.70, while PLN charges the excess cost of kVARH to the customer if the average power factor is less than 0.85. To be able to improve the low power factor can be done by using a capacitor bank, the capacitor uses the reactive power required at the inductive load. Changing the power factor in consumers can change. To equalize the power change factor, the capacitor bank is assembled to work multiple steps / multi steps. Multi-step capacitor banks consist of several capacitors with the same or different capacities. Based on the results of measurements before using the fuzzy logic method, the obtained power factor is 0.70 to 0.74 while the capacitors are installed from 12.5 kVAR to 25 kVAR. After using the fuzzy logic controller method the power factor obtained is 0.80 to 0.87 and capacitors using the 13.1 kVAR to 22.4 kVAR method. Whereas the power losses before using the fuzzy logic controller method are 26220.5 watts. After using the fuzzy logic controller method, the power losses incurred were 23214.45 watts.

In carrying out the ceremony at the Sindetan Temple, Les Village, we always keeps his tetaring. The tetaring that is installed is usually made of materials, namely bamboo, slepan (coconut leaves), and rope. In making the tetaring, a lot of manners are needed and have expertise in making tetaring. In addition, the cost of making the tetars is quite expensive and takes a long time. After completing the piodalan, the tetaring is dismantled where the materials cannot be reused for the next piodalan ceremony. This is because these materials will spoil quickly. The solution to this problem is in the form of innovation in making tetaring from materials that are more durable and stronger. The materials to be used are iron and cloth. This iron is used as a substitute for bamboo and cloth is used as a substitute for slepan and rope. The Service Team has designed the tetaring that will be made so that it has aesthetic value to be seen. In addition, the tetaring will be made easy and comfortable to use and can be assembled and assembled. Tetaring can be dismantled, meaning that if it is to be used, it will be easy to install and vice versa when it is finished, it will be easy to dismantle. The tetaring design is then realized and has been supervised in the process. The tetaring that have been made are installed at Sindetan Temple and then handed over to the Sindetan Temple board. This will provide effectiveness and efficiency for the Pura Sindetan boarding house. So that the manners of Pura Sindetan don't bother anymore thinking about tetaring when there is a piodalan ceremony.

Pura merupakan tempat yang disucikan oleh umat Hindu. Sehingga keberadaannya tidak dilengkapi dengan WC (Water Closet) umum. Hal ini disebabkan WC umum dianggap mengotori pura. Tetapi dengan perkembangan bangunan di sekitar areal pura maka disekeliling areal pura sudah ada rumah-rumah penduduk dimana sebelumnya masih berupa lahan kosong atau lahan pertanian. Dengan demikian para pemedek yang berada di pura apabila ingin buang air kecil akan mengalami kesusahan mencari tempat. Sementara ini, para pemedek yang berada di pura untuk melakukan persembahyangan atau ada kegiatan lain, apabila ingin buang air kecil terpaksa pinjem WC di rumah penduduk. Kejadian ini sudah dilakukan sejak dari dulu. Apabila hal ini terus dilakukan maka akan menggangu yang punya rumah serta para pemedek merasa tidak nyaman. Kondisi ini terjadi juga di Pura Dadia Tutuan. Solusi dari permasalahan ini maka krama warga dadia sesuai dengan hasil paruman maka berinisiatif untuk membangun WC umum yang khusus untuk tempat buang air kecil bukan untuk buang air besar. Prajuru dan Krama Pura Dadia Tutuan melaksanakan pertemuan untuk membahas dan memutuskan letak lokasi WC umum tersebut bertepatan dengan Hari Raya Galungan. Letak lokasi WC umum berada tepat di sebelah Pura Dadia Tutuan. Pemilihan lokasi ini karena tanah/area tersebut dimiliki oleh salah satu Krama Pura Dadia dimana tanah tersebut masih kosong dan pemilik sudah menyetujui pada pertemuan tersebut. Pembanguan WC Umum sudah dilakukan oleh warga Krama Pura Dadia Tutuan yang sudah ditunjuk pada pertemuan. Hasil Bangunan WC Umum tersebut sudah diserahkan kepada Krama Pura Dadia Tutuan melalui Prajuru, Warga, dan Tim Pengabdian. Kata kunci: Pura Dadia Tutuan, Desa Les, desain, implementasi, WC umum

Load balancing is a routine done by PLN to manage a distribution substation. It is done on Peak Load Time (WBP) only. Initial load measurements and load data on a distribution transformer need to be done for balancing as input of simulation software. The load imbalance in a power distribution system is due to an imbalance in single phase loads in the R, S and T phases in low voltage networks due to the imbalance of the load the current in the neutral transformer arises. The current flowing in the neutral of the transformer causes losses, i.e. losses due to neutral currents in the neutral conductor of transformers and losses due to neutral currents flowing to the ground. In this research load equalization in substation KD 056 was done by making a simulation on the ETAP program by measuring the value of the voltage on the KD 056 substation. The result of load balancing in KD 056 substation with the simulation ETAP program i.e. the voltage drop obtained from the percentage of KD 056 substation after being balanced by voltage drop on phase R which decreased from 7.30% to 1.36% from the 219VA source voltage. Once the KD 056 substation is balanced, it can lower the voltage drop and power losses, thus the system voltage meets the standards of PLN.

The large starting current in the starting process has the potential to damage theinduction motor. In minimizing the risk of damage, proper starting methods are needed. TheDirect On Line (DOL) method is a starting method commonly used in induction motors becauseof its economical installation and high work efficiency. The starting method which also has goodwork efficiency is the Variable Speed Drive (VSD). There needs to be a comparative analysisbetween the two methods to find out how the performance of the two methods is.Research results, the ongoing performance of the two starting methods on the fanmotor for cooling towers shows that the performance of the VSD method is superior to that ofthe DOL method. Starting performance on an induction motor can be seen from the efficiencyand economic value of the DOL and VSD methods. This performance is of course taking intoaccount the current, rotation speed and the resulting output power.

The load in the form of energy saving lamps has a harmonic loss generated. The harmonic effect generated is caused by the use of non-linear power electronic components, resulting in a current that is made into a distorted sinusiodal wave which results in the formation of waves at multiple multiples of the fundamental frequency. Based on the negative impact caused by the energy saving light, the filter was designed to reduce the THDi percentage generated by the energy saving light, by installing a low pass RC filter on the energy saving light.
