The results show that high energy of monsoon winds start from Indian oceans until Nusa Tenggara sea, then from Arafuru sea to Banda sea, Java sea, Karimata strait and the southern region of south Sulawesi.

This research is a study of conflict of interest which discusses about the interest of The United Nations Framework Convention on Climate Change on chosing the World Bank as the shareholders of the Green Climate Fund. The climate change has been a crucial issue that should be solved wisely. Many efforts had been tried for solving this issue, until the countries agree for making an operating entity of the financial mechanism of the convention (The Green Climate Fund) through the Conference of Parties of UNFCCC.This funding mechanism requires all developed and developing country to take their part in making the success of it.In this research, the author uses the group behavior analysis level which focused on the role of International organization. This research uses the diplomacy theory by Woodrow Wilson and the decision making theory, which are explain how the procedure for the decision is choosen.In effort to succeed this new agenda of UNFCCC, some critical statement come because the fact that, there are many developed countries that still using the dirty energy, which is the high factor of carbon emissions producer. The record of World Bank career in funding the countries which support and produce the dirty energy, also being one of the critic and obstacle. And the using of dirty energy of them still had increased right after the program declaration.

Energy is needed by people but sooner or later the world's oil reserves will be depleted. Generally energy needs are dominated by fossil fuels such as petroleum, natural gas and coal. It is time for Indonesia to reduce dependence on fossil fuels by developing alternative fuels that are renewable and environmentally friendly (renewable). There are three types of alternative energy that can be researched and developed in the world today such as biodiesel, bioethanol and biogas. One potential alternative to be developed was the use of bioethanol. Bioethanol is an alternative fuel that is processed from plants (biomass) by fermentation. In this study, the raw material used to make bioethanol is jackfruit seeds. During this time only used as a jackfruit seeds that only a small proportion of waste utilized as livestock feed and even largely discarded. In fact, if further processed jackfruit seeds can provide added value. This research aims to make bioethanol with various concentrations of yeast and fermentation time. The main process is hydrolysis fermentation using yeast Saccharomyces Cereviciae; and purification by distillation. The variables used were changes in the concentration of yeast 3, 6, 9%; and fermentation time 2, 3, 4 days. From the analysis of the research results obtained bioethanol yield per amount of raw materials best start was 10.9 ml/kg with a density of 0.959 g/ml and the calorific value sebasar 196.899 kkal/kg, ie at 9% concentration variation yeast and fermentation time 3 days. 130425007

Biodiesel is one of renewable energy in Indonesia that have to be development. Biodiesel formed as liquid fuel and has same property with petrodiesel. Biodiesel can be synthesized from off-grade palm oil using Na2O/fly ash as catalyst in transesterification process. Employing fly ash as support in Na2O has a good impact due to provide wide surface of catalyst. In this study aims to see the influence of reaction temperature, molar ratio of methanol and oil and concentration of Na2O/fly ash towards biodiesel yield. The process was conducted through reaction of esterification and followed by transesterification reaction. Processing of the data in this study was conducted by response surface methodology (RSM) using Design Expert 7.0 program which is experimental design determined by central composite design (CCD) which consists of three variables.
