Intergration of net zero energy building with smart grid to improve regional electrification ratio towards sustainable development | ||
Abstrak Indonesia is currently encouraging its physical, social and economy development. Physical development for economic development have to be supported by energy availability. For Indonesia, 90% of electrification ratio is still become an important task that has to be completed by the Government. However, the effort to increase electrification can become an environmental problem if it’s done with BAU s cenario. The by -product of electric generation is the GHG, which increasing every year since 2006 from various sectors i.e. industry, housing, commercial, transportation, and energy. Net Zero Energy Building (NZEB) is an energy efficient building which can produce energy independently from clean and renewable sources. The energy that is generated by NZEB can be used for the building its elf, and can be exported to the central grid. The integration of NZEB and Smart Grid can s olve today’s is s ue on electrification ratio. Literature study will find benchmarks which can be applied in Indonesia along with possible obstacles in applying this technology. | ||

Near Zero Energy House (nZEH) Design Variable for Housing Development in Indonesia | ||
Abstrak Housing development, as part of the economic development must be supported by energy availability in order to obtain a sustainable growth. One of the approaches to support the renewable energy promotions is designing and building energy efficient housing. However, optimal design of energy efficient buildings is facing two conflicting requirements, namely cost effective consideration and minimum environmental impact. The high costs from energy efficient building such as the Near Zero Energy House (nZEH) is due to high price of materials and equipment used, such as solar panel, insulation and other supporting materials. Indonesia is situatued at the equator and received sunlight throughout the year. Nonetheless, this potential has not been fully discovered due to the high cost of the solar generated energy technology for housing. Moreover, this technology is not integrated with the main electricity network. Thus, the objective of this study is to identify the design variables for nZEH that suit the tropical climate condition in Indonesia. Experiments and Case Study are used for the study, and the validated design variables for nZEH, which includes building orientation, PV, fenestration, and passive design, will be the basis for optimum nZEH design.

Fluid Flow Analysis of Micro Gas Turbine Using Computational Fluid Dynamics (CFD) | ||
Abstrak
The needs of micro-scale power plant for small and middle residential or industry are beginning to increase, especially for continuous power generation in remote area, emergency standby and peak shaving. There are several types of micro-scale power plant commonly used, such as micro-steam turbine, micro-hydro turbine, micro-gas turbine (MGT), etc. Among those micro-scale power plant, MGT has the highest performance. Therefore, it is a promising technology to develop. In MGT, an automotive turbocharger could be used as the gas generator or and the turbine because it has a compact structure, light weight and commercially available. In order to design a micro-gas turbine, it is necessary to find the optimum design of compressors such as the outlet compressor diameter, the combustion chamber and turbine. This paper describes the analysis of fluid flow in a micro-gas turbine that used an automotive turbocharger as the compressor and the turbine of MGT to generate electric power by using Liquefied Petroleum Gas (LPG). Three variations of compressor outlet diameter were developed and analyzed. The analysis shows that the compressor outlet diameter of 30 mm has a better velocity distribution, higher Mach number and higher turbulent intensity among other variants. The combustion chamber and the turbine also analyzed by using Computational Fluid Dynamics (CFD). The combustion chamber analysis indicates that the combustion of C3H8 and the air were mixed perfectly with maximum chamber temperature of 905.56 K. Meanwhile the turbine analysis indicates that the turbine rotated with a speed of 4087.96 m/s.
