Abstract

Availability of energy is an important aspect for the success of regional development. Yogyakarta city does not have any non-renewable energy sources such as liquid fossil fuels, coal and natural gas. Consequently,these energy must be supplied from other provinces. The renewable energy potential in Yogyakarta city is not being utilized yet. Final energy consumption continues to rise along with population and economic growth.Energy planning and development need be done carefully in order to ensure the energy sustainability. This study aim to provide long-term projections in 2012-2025 periods on energy balance, energy demand andsupply based on energy reserves and current condition in order to meet energy elasticity to less than 1. Energy demand projection is calculated based on trend forecasting analysis by LEAP (Long-range Energy Alternatives Planning System).This result shows that the highest energy user sector in Yogyakarta city period 2012-2025 is transportation sector and the highest of energy demand by type is electricity and gasoline. Renewable energypotential such as biogas, solar energy, biomass and biodiesel (from using vegetable oil waste) could be developed in Yogyakarta city. Using biodiesel and solar energy could decrease diesel fuel and electricity.According to the baseline scenario, CO2 emission reached 2,176,182 tons, the first alternative scenario reached 1,925,089 tons and the second alternative scenario reached 1,877,839. Investment cost to build renewable energy in the baseline scenario reached USD 42,045 – USD 546,585. Investment cost to build renewable energy in the first alternative scenario reached USD 10,470,775 – USD 31,002,775. Investment cost to build renewable energy in the second alternative scenario reached USD 31,641,925 - USD 52,173,925.

Abstract

This paper presents a techno-economic potential and feasibility analysis on the planning of Biomass renewable energy from palm oil mills on the North Penajam Paser Regency. They were analyzed using the last three years of production data history from 7 Palm oil Processing Factories in the region and using questionnaires and interviews. Total processing fresh fruit brunch is about 891.624 tons/year. Total potential electricity generated from palm oil residue (Fiber, Shell, and Stem) is 28.009 kWh. The factories are located in Babulu, Waru, Penajam, and Sepaku.The assessment of sustainability indicators in this research is considering technology and economic aspects. The technology aspect evaluates the technical planning of installations that are possible to build in the area. For financial aspects of sustainability, evaluates the net present value (NPV), internal rate of return (IRR) and, the payback period of renewable energy installation. This analysis is used to get a comprehensive insight from the potential biomass energy at the research location and conduct a feasibility study based on techno-economic analysis to develop new state capital Indonesia and the supporting regions.

Abstract

The need for energy and electricity in a number of regions currently tends to increase every year. The fast pace of modernization and increasing economic activity in various parts of Indonesia are the main factors triggering the increase in energy demand. The data analysis technique in this study was using quantitative correlation methods with questionnaires and data from field observations. Data in the form of questionnaires and data from observations are primary data in this study. The purpose of this survey is to measure the performance of Micro hydro Power Plants (MHPP) at each site using KPIs related to the sustainability of the site. In addition to verifying objects that are connected and not connected to the MHPP, this survey also covers topics related to the sustainability of the MHPP site which includes operational status, finances, checking of physical components and the results obtained. Based on a survey conducted on the five MHPP sites, there are 325 houses stairs, 24 social institutions, and 28 PUE, Non-functioning buildings are the main reason, Damage to components and the presence of new generators are the main reasons behind MHPP not operating, There is a correlation between MHPP performance and customer satisfaction, Tariff system applied by all MHPP sites is a fixed rate with a cost of Rp. 20,000.00 to Rp. 30,000.00, All MHPP sites, Damage to generator and ELC components, Deforestation occurs in all MHPP sites, and Based on physical checks on MHPP.
