Abstract

This paper aims to analyze the integrated management of water, energy, and food resources within the context of the Water-Energy-Food (WEF) Nexus in Magelang Regency, Central Java, Indonesia. The focus is on the projections for electricity demand, water needs, and potential electricity production from microhydro power plants (PLTMH) by 2030. The methodology involved simulation models using the LEAP and WEAP software to create a conceptual management model that promotes sustainable resource use. Our findings project electricity needs in Magelang Regency to increase significantly, estimated at 79,626.3 MWh under the baseline business-as-usual scenario, 90,281.53 MWh for a moderate scenario, and 92,201.78 MWh under an optimistic scenario, with the moderate and optimistic scenarios representing increases of 13.38% and 15.79%, respectively, over the baseline by the end of the projection period. Concurrently, water demand is projected at 349,953,115 m³ under the baseline scenario and slightly less at 339,542,991 m³ considering the impact of the new Yogyakarta-Bawen toll road, with a variance of 3.07% between the scenarios by 2030. Additionally, the potential electricity production from the proposed PLTMH is projected at 590.67 MWh by 2030. These projections underscore the critical contributions of sustainable infrastructural developments such as PLTMH, which, despite regulatory support, have not yet been constructed in the regency. This research illustrates the need for robust planning and integration of sustainable practices within local governance to achieve the objectives outlined in the Sustainable Development Goals (SDGs), emphasizing the importance of sustainable and innovative solutions to meet future demand for these interconnected resources effectively.

Abstract

The focus of this research is to utilize wind energy for power generation as an electric power service for shrimp farming in the Kulon Progo district of Yogyakarta. This is done in order to minimize the use of diesel fuel in daily operations to drive the aerator pump that produces air bubbles and needs lighting. The method used is to calculate the need for electrical power in 24 hours, plan the windmill according to the local average wind speed. Parameters for measuring the final result are net present cost (NPC), cost of energy (CoE), and payback period. The scenario is used by installing a wind power generator compared to a generator from a diesel engine. The results of the study with a wind power generation system capable of producing 41755,07kW/year of power with the NPC value having a more efficient economic value of Rp. 158,254,000.00, a more efficient CoE value of Rp. 477.41, and for a diesel power plant of Rp. 1,569,015,240.00 and CoE worth Rp5,867,45. The payback period for the scenario with wind power is 3 years and 9 months and and 15 years 7 months for the scenario with diesel power plants.
