ABSTRACTThis study analyzes the factors that determine firms' decisions on electricity self-generation in Indonesia. Specifically, I explore the difference in firms' decisions making across Indonesian five major islands in the past ten years. The empirical investigation utilizes Indonesian's Large and Medium Firm dataset of the years 2004, 2009, and 2014. The empirical results show that industry with higher output, higher income, and less labor is positively associated with the probability of electricity self-generation. Moreover, for firms in Kalimantan and Papua/Nusa Tenggara/Maluku island, they have a higher probability (24.7% and 19.8%, in comparison with Jawa/Bali island) of the electricity self-generation. The agriculture sector is also more likely to self-generate electricity. The year effect on the study indicates that in 2009 the firms reduce the usage of self-generated electricity. All of these findings are robust across different model specifications."

"To solve current environmental problems such as global warming and declination of fossil fuels, use of less energy is essential, particularly in the fields of refrigeration and air conditioning. Thus, simulations using complex mathematical models become vital. Simulation technology faces a major challenge because the language of simulation codes varies depending on the programmer. Thereafter, others cannot duplicate the same simulation technology used by their predecessors. To address this, a modular analysis method that generalizes simulation code has been developed. With this method, the general-purpose software analyzing energy system called “ENERGY FLOW +M,” a software enabling analyses that can be conducted without having to specify the model or the method of analysis used, has also been created. The focus of this study was on the solar collector. As the solar collector uses energy from the sun, it is friendly to the global environment. In order to understand the performance of the solar collector, the construction of a simulation model was carried out. Moreover, models of the solar collector and solar radiation were loaded into “ENERGY FLOW +M” to verify their performance. Thus, this simulator allows us to execute simulations of the solar collector from anywhere via the Internet."

ABSTRACT

Kepulauan Seribu Regency is one of the priority tourism development areas in Indonesia (National Tourism Strategic Area). An increase in tourism sector will increase energy needs as one of the primary needs of tourism activities. Meanwhile, the potential of renewable energy can be an energy source used to be utilized in Kepulauan Seribu. The purpose of this study is to know the projection of energy demand for the tourism sector on each island that will be compared with the government's plan of the energy supply for each tourist destination island. Those islands that have a higher consumption projection compared to their planned fulfillment are considered as energy deficit areas which are then assessed for the suitability of renewable energy systems using Spatial Multicriteria Analysis method. The results show that the energy deficit region for the needs of the tourism sector consists of Pulau Tidung, Pulau Harapan, Pulau Ayer and Pulau Putri. Based on the results of the spatial multicriteria analysis to determine the suitability of Wind Turbines and Photovoltaic Systems, Photovoltaic system has the potential to be developed in the deficit area, while the wind turbine system is not suitable to be developed in those deficit region. The results of regional mapping show that the potential of energy that can be generated by photovoltaic systems based on the area that is very suitable are able to fulfill the insufficiency of energy supply needed in 2022."
