The results of the inspection of the material condition are good but it is necessary to clean the results of the manual power loss calculation before the repair is 472.207 Watts after the repair there is a decrease, namely 146.7 Watts calculated using recorded load measurements at 10.00 WIB and 19.00 WIB from April 2, 2022 to April 24, 2022:} }
