| Summary: | Bunaken Island is located within the administrative region of Manado City. Located
to the north of Manado, Bunaken Island covers an area of 8.08 km2. The electrical
system on Bunaken Island relies on a Diesel Power Plant (DPP) with four machine
generators, providing a daytime capacity of 300 kW and a nighttime capacity of
380 kW. In 2023, repairs and rehabilitation were carried out on the Solar Power
Plant (SPP) due to fault since 2018. SPP is expected to reduce the reliance on DPP.
This paper analyzes the existing operational pattern of the DPP to identify changes
that can improve fuel efficiency. Subsequently, it investigates the hybrid operation
of the SPP and DPP to achieve the most efficient use of fuel while considering
engine performance factors, specifically Specific Fuel Consumption (SFC). The
analysis in this paper utilizes the SOLVER plug-in available in Microsoft Excel.
From the analysis of the comparison of existing PLTD operational patterns, the
fuel usage efficiency is found to be 46.35 liters per day or equivalent to Rp 532,147
per day, with an improvement in SFC from 0.292 liters/kWh to 0.279 liters/kWh.
Additionally the hybrid operation pattern of SPP and DPP, is found that the
inclusion of energy from the SPP will reduce High Speed Diesel (HSD)
consumption to 391.72 liters per day or equivalent to Rp 4,497,693 per day, with
an improved SFC) of 0.259 liters/kWh. However, economically, adding additionally
battery capacity is not feasible. |
