Abstract

PLN as an electricity provider that serves all regions in Indonesia certainly always wants to provide the best service to its consumers, including PT. PLN Persero UP3 Gresik. Along with the increase in consumers, the company continues to develop distribution lines, however, because the addition of more and more lines makes the distribution cables longer and the load becomes greater, resulting in voltage drops and power factors decreasing in several feeders, including in the feeder network. LOWAYU, causing poor power quality.This research aims to find and obtain the magnitude of the power flow which includes active power, reactive power, apparent power and the magnitude of the power losses (losses) contained in the LOWAYU feeder network, the magnitude of the voltage and voltage drop on each bus on the network. LOWAYU feeder using the backward-forward method. And determine the value of reactive power required for the capacitor on each bus that experiences a voltage drop. Then a comparison will be made between the results of manual calculations using the backward-forward method and the results of simulation data using ETAP Power Station 19.0.1 software.From this research, it can be seen that the safe limit for the voltage drop value is still below 5% or above 5%, so it is necessary to add capacitor banks to improve the power factor and reduce the voltage drop value on distribution network buses that experience voltage drops.

Abstract

This study aims to: 1) determine the effect of the Make A Match Learning Model assisted by the Snakes and Ladders Game Media on Learning Activity in Grade III IPAS Learning SDN 87 Singkawang; 2) find out how much influence the Make A Match Learning Model can increase Learning Activity in Grade III IPAS Learning SDN 87 Singkawang; 3) find out the student's response in using the Make A Match Learning Model assisted by the Snakes and Ladders Game Media on Learning Activity in Grade III IPAS Learning SDN 87 Singkawang. The research method is Pre-Experimental Design with One-Group-Pretest-Posttest-Design. Data collection techniques in this study used non-test techniques, namely, observation and questionnaire. The instruments in this study are, namely, Student Activity Observation Sheets and Response Questionnaire Sheets. The population in the study were all third grade students of SDN 87 Singkawang. The research sample was taken by non probability sampling with a saturated sample totaling 22 third grade students. The prerequisite test carried out is the normality test using SPSS 25 for windows software. The first hypothesis testing uses the N-gain test, the second hypothesis is the Dependent t-test and the third uses the average formula. The results showed that: 1) There is an increase in student learning activeness by using the Make A Match model assisted by snakes and ladders game media with the N-Gain test of 0.68 classified in the medium category; 2) Based on the results of calculating student data using the SPPS application using the Dependent T-Test Test, it is known that the Sig. (2-tailed) is 0.000 <0.05, then H0 is rejected and Ha is accepted. So that the results obtained are, there is an effect of using make a match learning assisted by snakes and ladders media on student learning activeness; 3) based on the average data of the response questionnaire that researchers gave to students after the Post Test, the percentage of each indicator of student response was in the very good and sufficient category. The highest percentage is in the conclusion indicator which is 100%. From each of these indicators that can affect students' responses in learning. Then the average percentage of the overall student response was obtained at 93% in the very good category. So the results obtained are, there is a positive student response to the Make A Match model assisted by snakes and ladders media.
