Bambang Winardi, Karnoto Karnoto, Ajub Ajulian ZM
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… r 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.

Dwi Dewianawati, Erry Setiawan, Dian Indrianto, Buyung Cahya Perdana, Harjo Lukito, Ratna Agustina
Abstract: Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the national economy; however, tax compliance, particularly related to Income Tax Article 21, remains relatively low. The main challenges faced by MSME&#8230; E actors include limited tax literacy, complexity in tax calculations, and insufficient understanding of recent regulatory changes. To address these issues, the government introduced the Average Effective Rate (TER) scheme as an administrative simplification for calculating Income Tax Article 21. Nevertheless, the implementation of this scheme has not been fully understood by MSMEs at the village level. This study aims to conduct socialization and training on Income Tax Article 21 based on the TER scheme for MSMEs in Watesprojo Village and to evaluate its effectiveness in improving tax understanding and technical capability. The research method involved initial observation, regulatory socialization, practical tax calculation training, and participant evaluation. The results indicate a noticeable improvement in MSME actors’ understanding of the legal basis of Income Tax Article 21, the changes in the calculation scheme, and the practical application of the TER mechanism without disrupting business activities. Overall, the socialization and training activities proved effective in enhancing tax literacy and supporting sustainable tax compliance among MSMEs.
