Abstract
The DKI Jakarta and Banten Load Management Implementation Unit is one of the load control areas in the Java Bali system which participates in load regulation and has 10 subsystems. However, in the current conditions, the Gandul 1.3 - Muarakarang - Kembangan 2 subsystem has several system vulnerabilities. the most transmitted is on the Durikosambi-Kembangan cable channel which has an OCR setting of 1100 A (800 A limitation related to cable capacity and cable age factor at the request of the asset owner). This channel is the main route connecting the Muarakarang generator with IBT Gandul and IBT Kembangan2. For the Durikosambi IBT defense setting scheme, it uses the setting pattern that was previously applied to the Durikosambi-Kembangan SKTT with the same load target, only commissioning from the Durikosambi-Kembangan SKTT to Durikosambi IBT 1 and 2, with it being two new subsystems, there is no need to worry anymore about taking on Durikosambi-Kembangan SKTT so that electricity services can be optimal and the No Outage Zone can be maintained properly. With the operation of GISTET Durikosambi, the operational pattern for the Muarakarang Power Plant has changed, namely Muarakarang Block 1 and PLTU Muarakarang 4-5 can be positioned on standby (Reserve Shutdown). So the generating unit operating is only in Muarakarang Block 2 with an assumed operating pattern of an average of 680 MW in 24 hours
