Even Indonesia as the biggest economy in the region puts only a 31% target of renewable energy mix in its energy roadmap by 2050. It is far from the ideal level set by the Global Wind Energy Council at 70%. However up until now, there is no specific research that analyze and compare the energy roadmap among ASEAN country, in regard to the development of renewable energies, especially related to their dependency on fossil fuels. This thesis is aimed to elaborate more on why countries in the region tend to set conservative targets in their energy roadmap, and whether it is heavily related to their dependency on fossil fuels. And later, we can see the opportunity to invest in renewable energy in the region timely.

A measuring instrument to indicate a brake vehicle whether it is still feasible or not to operate has not yet been implemented in Indonesia. This is because the formulation of the feasibility of a brake that has been operating for a certain time has not yet achieved maximum results. So this research is considered very useful to be developed in order to reduce the number of accidents in Indonesia. Excess heat (overheat) is a phenomenon that occurs due to damage to one element of the braking system, where this can result in total brake failure. the imbalance of the grip each brake is approximated to affect the balance of the vehicles motion when braking is done on a straight road or on a turning road. Braking loads can be calculated from the size of the normal force on each wheel in braking conditions. The initial stage in solving this problem is to define the form of loading on a brake system as a whole, to then be applied in numerical simulations of temperature distribution using FEM (Finite Element Method). Heat flux is the rate of heat energy transferred through a surface per unit time. In this study will be discussed about brake temperature which is a brake performance indicator whether it is within normal limits or not.

The Computational Fluid Dynamics (CFD) method used for simulations uses the Eulerian-Eulerian approachs incorporating the Kinetic Theory of Granular to calculate the motion of particles and the standard k-e turbulence model to simulate the fluid flows. The simulations were carried out using four different air mass flow rates, based on the air consumption in the combustion of coal used in real CFB boiler. Since this simulation is the preliminary study of the particle dynamics in CFB, the combustion process had not simulated yet. In this work, the complex flow has been resolved by applying the CFDSOF commercial CFD software. The distribution of pressure, particle velocity and volume fration in the CFB were investigated to obtain the optimum results of the fluidization. The simulation results showed that at the actual air flow rate, the fluidized bed showed the bubble instead of turbulent fluidization, and increasing the velocity swifted it into the turbulent. The optimum air flow found to be between 60% - 75% of excess air value.

Many ethnic groups in Indonesia see the sea as something sacred apart from the profane. Traditions and rituals related to the sea are a sign of respect for the sea. Likewise in Chinese society in Indonesia, respect for the sea appears with the existence of temples located on the coast. Globalization is characterized by the loss of local wisdom and the loss of sacred traditions, but here can be seen the persistence of local wisdom traditions in viewing the sacred. This form of respect for the sea as a form of local wisdom in Chinese society in Indonesia manifested itself in the tradition of respecting the sea guardian deity in the temple. The study was conducted using ethnographic research methods, which were carried out in several temples that had sea guardian deities as host gods, such as in Makassar, Jakarta, Krawang, and Madiun. The tradition of respecting the sea protective deities in Chinese temples in Indonesia shows local wisdom in maritime society. Respect for the sea guardian deity (Mazupo) in XianMa temple, Makasar, Sian Jin Kupoh temple, Krawang, Dizangyuan temple, Jakarta and Hwie Ing Kiong temple, Madiun shows the Chinese believe in a sacred thing manifested in the deity by presenting offerings.

Ahmad Rozak Ari Artadi, Ph.D Universitas Darma Persada Abstract Japanese companies that invested in various ASEAN countries mainly in manufacturing sector already established global production chain. That means even if the parts were produced in different plants in various countries, however the parts have same standard and the results is high accuracy, therefore when the parts were assembled on assembly line, all the parts can suit each other, and yields the ultimately good finishing products. It does not matter where the finished products were assembled, because all the countries have same standard of production. However, in order to achieve the high accuracy products in delivery target, the companies need high skill human resources which have similar attitude and abilities. Manufacturing means making things or add value to the material, and the most important thing in the process is to educate people who make the products. Making high quality products which affordable price and satisfied the customers is not a simple process. It needs workers who have excellence skill, spirit, zest and pride to make product perfectly well, which known as monozukuri. This is the ultimate reason why monozukuri should be taught to Indonesian students. Based on discussions, surveys and interviews with Japanese institutions, companies and experts, actually the companies need workers with good communication abilities, understand manners, work ethics, and good team work. From the companies needs, we define that monozukuri course should have learnings elements such as Japanese language, Japanese manners, Japanese corporate culture, 5S activity, Horenso, Kaizen+3M, QCC and PDCA, Kanban+JIT, Visual Management, Factory visit and A3 report.

Transesterification method has been widely used in the process of making biodiesel. This reaction is a slow reaction because it takes place in a two-phase system. These problems can be solved by the addition of non-reactive co-solvents. The addition of the co-solvent aims to form a system of solutions which originally two phases into a single phase because the solubility of alcohols in the triglycerides is very low. THF is also more economical and healthier for biodiesel production because it comes from biomass and non-toxic. The results showed that transesterification with the addition of co-solvent resulted in higher methyl ester content than conventional method.

EFB can be efficiently converted into valuable and useful fuel products through gasification. Gasification is a process of biomass conversion into syngas. Syngas is a raw material for most other chemical products, such as Methanol, Ammonia, and DME. One of the biomasses that has big potential and available abundantly is palm EFB waste. Research about DME synthesis from various biomass has been done. Although little research about DME production based on EFB gasification was carried out, there is no research yet being conducted on techno-economic analysis of DME Plant construction based on EFB gasification. The aim of this research is to find feasibility of small scale DME plant model based on gasification of palm EFB with 6.16 tons per h EFB feed to plant. Method encompasses step to perform simulation of the model and DME plant design, to do equipment sizing, to conduct costing, to calculate investment cost estimation, to calculate operating cost estimation, and calculation to estimate profitability in term of BEP, and calculation of economic feasibility parameters. The model predicts yield of DME product in agreement with published real DME plant operation. The result shows flow rate of DME produced is 50% of EFB feed flowrate and 73% energy efficiency obtained for pre-treated EFB. Electric power requirement has been investigated at 3683 kW and can be fulfilled by DME Plant through waste heat steam generation cycle and internal combustion engine fuelled by off-gas. Economic analysis calculated that the total investment to build DME plant in this study was USD 104,291,799. NPV calculated was USD -42,393,967, IRR at 4.2%, and PBP 18 years. Based on NPV, IRR, PBP calculated, DME plant construction based on gasification of EFB is not feasible. Feasibility can be attained, if discount rate lower than 4.4% applied. It was estimated that 4 times increase in capacity makes DME construction process feasible.

The Pico hydro system is examined by using water energy from pump that flows of water in simulator system with various type of water pressure and water flow rate. Why we use centrifugal pump, because they are easy to accessible, cheap and work steadily with simple system. And it is also quick and easy to construct with simple equipment. The author make a simulator equipment to see the performance of the centrifugal pump as a turbine and recorded a few of parameters in the close-loop system. This compact type simulator is expected to be easy to use, set up and can recorded a few of parameter. We used incandescent light bulbs as a load because they are accessible, cheap and work steadily with simple power supply. It is also quick and easy to construct with simple equipment. The construction of the simulator consists of two main parts; the centrifugal pump as a water turbine and Multi stage pump as a power to flows of water. From this evaluation, we can see that the greater the water flow and or water pressure that drives the pump as a turbine, the higher the power is produced. From this data that the power is marked straight towards the water flow and water pressure. In this study shows that centrifugal pumps can function as water turbines and are an alternative to produce electricity. And the use of a pump can easily be accessed in the market and easy to maintain, we can easy to use this in rural area.

 73 ABS-31 Renewable Energy Engineering, Technology and Management Science REVIEW ON MARINE ENERGY PRORAMKamaruddin Abdullah Darma Persada University Abstract Indonesias marine energy potential is estimated to reach 48 GW, but only a small portion has been realized. The world potential for tidal energy is estimated to reach 500 to 1000 TWh. Indonesias experience in wave- current energy was conducted by Erwandi et al, in 2010 where they designed ad consrutcted a current-wave power generations producing 2 to 10 kW electricity and tested in Larantuka Strait, Flores Island. In 2005 a group of ITB students had started to design and construct a 5000 We capacity ocean current and tested at Nusa Penida, Bali. Later they constructed a one 10 kW unit which has been installed at Madura strait to provide 1000 lighting of the Suramadu bridge, Surabayam(T-files, 2013). .Indonesia is also potential place for Ocean Thermal Energy Conversion (OTEC) and other marine energy because of the difference in temperature of sea surface and the deep sea water temperature is always constant at around 24 degree Celsius which is adequate to operate an open cycle OTEC. Beginning in 1970 the Tokyo Electric Power Company successfully built and deployed a 100 kW closed-cycle OTEC plant on the island of Nauru.The plant became operational on 14 October 1981, producing about 120 kW of electricity; 90 kW was used to power the plant and the remaining electricity was used to power a school and other places.A 1 MW OTEC project was built in South India for clean water production with capacity of 7000 gallons/day by NIOT in cooperation with Prof. Ikegami from Saga university Japan in 1997. An OTEC project was built in Hawaii where it could produce 103 kW between 1993 to 1998. Another successful OTEC project is the one located at Kameshima, Okinawa Island of Japan built in 2013 where 100 kW of electricity could be produced.. Now a 10 MW OTEC is under construction in Hainan Island, Southern China. In Indonesia recently a Tidal Bridge BV announced it has begun the feasibility study for the 18 to 23-MW Palmerah Tidal Bridge project located at Larantuka Strait. It will be constructed at the end of 2108. Keywords: Marine energy potential, OTEC, tidal energy, marine energy projects.

 75 ABS-43 Renewable Energy Engineering, Technology and Management Science PERFORMANCE OF AGRICULTURAL WASTES ON SMALL-SCALE DOWNDRAFT GASIFICATION SYSTEMSSyukri M. Nur, Yandri Erkata, Tanda Akhesta Sunu W , Jumino, Gatot Dwi Adiatmojo, Rusydi M. Yusuf, Aep Saiful Uyun and Kamaruddin Abdullah Graduate School of Renewable Energy, Darma Persada University Abstract Biomass derived from agricultural waste, plantation, and forestry industry in Indonesia is a bioenergy raw material that is abundant and has not been used as a source of energy raw materials. This article aims to present the performance of the four types of agricultural waste which are coconut shells, rice husks, empty fruit bunches, and sawdust used for a small scale downdraft gasification system. The initial treatment given to the four types of waste is drying under direct sunlight for two days to achieve a water content of <10% wt. Furthermore, the energy conversion process is done on a small scale gasification system as an initial step to build a biomass-based power generation system that can be used in agricultural areas. The characteristics of agricultural waste measured are amount of raw materials, the rate of combustion, the amount and the chemical content of tar and biochar, as well as the ability of these biomass gasification system to generate electricity through a small gas engine. Based on the results of the initial experiments showed that the downdraft gasifier was able to convert these raw materials into combustible gas with production rate and quality that will be tested in the next stage. t.

 76 ABS-44 Renewable Energy Engineering, Technology and Management Science Portable Conveyor of Solar-Energized Foodstuff Dryer SystemHerry Susanto(a), Yefri Chan(a), Syukri Muhammad Nur(b), Husen Asbanu(a) a) Mechanical Engineering Department, Universitas Darma Persada. Jl. Radin Inten II, Pondok Kelapa 13450, East Jakarta, Indonesia b) Program Study of Renewable Energy, Graduate School, Universitas Darma Persada. Jl. Radin Inten II, Pondok Kelapa 13450, East Jakarta, Indonesia Abstract The rain could be occured at the harvesting season. Hence, drying process could be delayed. This will cause the ingredients mold or germinate. So it could not be consumed or sold. Currently the quality of dried foodstuff whether for export or domestic consumption are still in a low quality. The raw material of dried foodstuff processed by drying on the open area, for example above the road surface, the home yard and the roof top. It cause the quality of dried foodstuff less hygienic. So it tends to have some problems, for example contaminate with dirt and microorganisms, eaten by chickens, birds, mice etc. Because of the agricultural products for export require consistent quality, and continuous supply, So the process of foodstuff drying should be replaced with a drying method that is not affected by the weather. To overcome this problem, a portable conveyor of solar-energized drying system (CSDS) was designed. With the portable CSDS, the dryer will be easily moved and flexible to use. However, such system has not been widely used for the drying process in Indonesia. It is because the limited research of the dryer type. The advantage of portable CSDS is that the drying process could be done continuously with a little human power. Therefore, this portable CSDS is designed to use renewable energy sources. To examine the portable CSDS, the vermicelli noodles was used for a testing of ingredients. The portable CSDS testing show that the amount of water content in the ingredients reduced, the drying rate accelerate. In addition, the amount of heat energy needed for the drying process also reduced. So the process of drying foodstuff more efficienct.
