Gas and steam power plants (PLTGU) currently have an essential role as national electricity providers, including the Grati PLTGU, which contributes to maintaining reliability in the Java Bali Network system, especially in the eastern region. PLTGU Grati block one is designed to operate with two fuel types (dual fuel), gas and HSD. In certain conditions where the system needs are high, and the limited gas supply, the Grati PLTGU is requested by P2B to operate even with HSD fuel so that the condition of plant readiness must always be maintained, including the fuel system. One of the disturbances that cause the Starting failure (SF) status in G 1.2 PLTGU Grati is the failure of the MFO Pump Trip caused by low suction pump pressure (touching the trip limit of ≤ -0.3 kg/cm2).
