Abstract

Load balancing is one of the things that must be considered by reducing the value of voltage drops or power losses that occur in distribution channels. It is necessary to know the characteristics of the load in an area or area with a balanced supply so that each phase is burdened evenly. Calculating the voltage drop on the distribution network conductors, the voltage drop on the KBN09 Slawi feeder was calculated. What will be calculated here is from the line to the transformer furthest from the GI, namely from the three-phase 20 kV main line, single-phase branching. The results of power calculations from GI Kebasen Tegal show differences between R, S and T phases with three 20 kV phases in pre-balance and post-balance conditions. As written, the value for R wire is 82661.52 W, for S 52613 W, while for the T phase the value is 60127.06 W. Meanwhile, the calculation of power losses from GI Kebasen Tegal shows differences between the R, S and T phases with 1 phase voltage in the conditions before balance and after balanced. On the 3-phase line for the R wire, the power loss decreases from 34,198 W to 17,0425 W, for S it increases from 11,540 W to 19,077 W, while for the T phase the value remains 15,274 W.

Abstract

The Department of Education, Youth and Sports is a government agency that operates in the formal and non-formal education service sector as well as in managing education governance in schools. The Department of Education, Youth and Sports has a structural field, one of which is the SUPEG field "General and Personnel Sub-Section", where it deals with a lot of issues related to general and personnel, one of which is incoming and outgoing letters. However, there are obstacles and problems faced, namely that incoming and outgoing letters often have double numbering, some letters cannot be found, the archive process is still manual and there are many other problems. With the existence of this incoming and outgoing mail archive website, it is hoped that it will be useful and can solve this problem at SUPEG in the future. The website was designed using native PHP language and several collaboration languages, namely JavaScript, CSS and others, for the database itself using Xampp. The final result of this research is the production of an Archives Website for Incoming and Outgoing Mail. who can provide information and solve problems that occur in SUPEG "General and Personnel Sub-Section" especially in the correspondence section both within the agency and from outside.

Abstract

The Gondoriyo 1-phase network has a network length of 3.2 km supplied by a 1-phase network that is charged in phase S on BSB 1. The extent of the service area makes the load on phase S jump high. The measurement results obtained by the load current during peak load reached a total of 62A. While the load current of the repeater at the time of peak load is phase R of 32A, phase S of 98A, and phase T of 44A. With such conditions, it is necessary to expand the medium voltage distribution network in the Gondoriyo area with the aim of balancing the load on the BSB 1 extension. To facilitate load sharing in the expansion of the Gondoriyo area, the ETAP powerstaion 7.5.0 simulation program is used. which consists of 1 phase simulation before expansion and 3 phase simulation after expansion. From the results of this engineering shrinkage simulation, the total engineering shrinkage value in the 1-phase network before the expansion was 6480 kW, after the network expansion, the total engineering shrinkage changed to 2510.4 kW. With the simulation that has been made, it is expected to produce a load sharing plan that will make it easier for PT PLN (Persero) Rayon Boja to share the load on the network after the expansion.
