Recently a comprehensive source of data and information on carbon storage in various types of forest ecosystems and other land use in Java Island are still limited. This study was carried out in a conservation area of Bromo Tengger Semeru National Park (TNBTS) that represents the ecosystem types of lowland rain forest, sub-montane forests and mountain forests in Java. The information on carbon sequestration and carbon stocks at TNBTS becomes important. The main objective of this study was to estimate biomass and carbon storage in various types of forests in TNBTS using allometric approaches. The additional objectives were to estimate carbon storage on various land cover and to estimate the changes in carbon storage by land cover changes during the period 1990, 2000 and 2013. The measurement of forest carbon include aboveground, understorey, necromass and litter pools covering all ecosystem such as primary forest, secondary forest with high- and low- canopy density. This study found that the average of carbon stocks in primary forest were 193,49 ± 125,98 tonC/ha, and were 267,42 ± 119,25 tonC/ha in secondary forest. The total carbon stocks in the period 1990–2000 has decreased about 22.6 tonC/ha/year and in the period 2000–2013 has increased about 41.2 tonC/ha/year. The enhancement of carbon stocks in this area was driven by an intensive forest protection, good monitoring and land rehabilitation.

Agroindustries in general produce a large amount of organic wastewater. Until now, most of this organics waste-stream was not recovered and left to decompose anaerobically in ponds, where it emits methane, a potent greenhouse gas. By anaerobically digesting of the effluents in a suitable bioreactor, methane can be captured and used for combustion in gas engines or boilers. This way, uncontrolled methane emission from the anaerobic decomposition can be avoided and the utilization of fossil fuels can be replaced partly with the renewable biogas from the decomposition process. In addition, the approach of reducing green house gas emission is potentially to earn financial incentive through Clean Development Mechanism project. This paper demonstrates quantitatively some potential ecological and economical benefits derived from utilising agroindustrial effluents by treating it anaerobically to generate biogas (with cases of cane sugar factory, starch industry, palm oil mill, and tofu industry) . As illustration, for each ton cane sugar produced app. 15 m3 methane can be emitted from uncontrolled anaerobic degradation of it wastewater. By capturing the gas and transforming it into renewable biogas, a methane emission of equivalent to ≈ 272 kg CO2 can be avoided and an energy value of app. 427 MJ with a money value of app. Rp 59 600,- can be obtained. In addition, a financial incentive of app. Rp 14 850,- is possible to be earned from clean development mechanism (CDM) project. The ecological and financial benefits derived from anaerobic treatment of agroindustrial wastewater as indicated by this study should therefore become the driving force for the implementation of the approach.

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

Kemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) merupakan salah satu jenis tanaman penghasil minyak nabati yang memiliki potensi besar sebagai sumber bahan baku untuk biodiesel. Tingkat produktivitas yang dapat mencapai 8-9 ton minyak kasar atau setara dengan 6-8 ton biodiesel/ha/tahun memiliki nilai strategis terkait dengan program pemerintah dalam mencari alternatif sumber energi baru yang terbarukan. Pengembangan sumber energi terbarukan seperti yang berasal dari minyak nabati kemiri sunan merupakan salah satu alternatif dalam upaya memenuhi defisit energi untuk keperluan domestik sehingga Indonesia dapat keluar dari himpitan krisis energi. Lahan-lahan yang telah terdegradasi di Indonesia dari tahun ke tahun luasnya semakin bertambah baik karena faktor alam maupun karena eksploitasi yang tidak terkendali. Disisi lain pengembangan tanaman sumber BBN terkendala karena keterbatasan lahan. Kajian yang telah dilakukan secara intensif terhadap karakteristik tanaman, minyak dan biodiesel yang dihasilkannya, serta daya adaptasinya yang sangat luas terhadap beragam agroekosistem yang ada di Indonesia, tanaman kemiri sunan memberikan harapan yang baik disamping sebagai sumber bahan baku biodiesel, juga dapat berfungsi sebagai tanaman konservasi untuk mereklamasi lahan-lahan marginal yang telah terdegradasi. Disamping itu, pengembangan tanaman kemiri sunan di lahan yang telah terdegradasi tidak hanya akan dapat meningkatkan nilai ekonomi lahan tersebut, tetapi juga dapat dijadikan tanaman yang bernilai ekonomi tinggi, serta mampu menyediakan kebutuhan energi bagi masyarakat sekitar maupun ke wilayah yang lebih luas. The Multiple Benefits of Developing Kemiri Sunan (Reutealis trisperma (Blanco) Airy Shaw) In Degraded LandKemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) is one kind of vegetable oil crops that have great potential as a source of raw material for biodiesel. The productivity level that can reach 8-9 tons of crude oil, equivalent to 6-8 tons of biodiesel/ha/year make as a strategic commodity associated with government programs to find alternative sources of renewable energy. Development of renewable energy such as from vegetable oils of kemiri sunan is one of the alternatives in an effort to solve the deficit of energy for domestic use so that Indonesia can way out of the crush of the energy crisis. Lands that have been degraded in Indonesia continuously increasing both cause of the extent of natural factors and uncontrolled exploitation. On the other hand the development of this plants retricted by aviability of land. The research88 Volume 14 Nomor 2, Des 2015 : 87 - 101 studies have been conducted on the characteristics of plants, oil and biodiesel production, and adaptability in very broadly of Indonesian agro-ecosystem, this plant show well hopes besides as a source of raw material for biodiesel, it can also function as a conservation plant to reclaim marginal lands that have been degraded. In addition, the development of kemiri sunan on degraded land will not only be able to increase the economic value of the land, but also can be used as crops of high economic value, and able to provide for the energy needs of the surrounding communities and to the wider region.

Petroleum reserves are depleted in Indonesia along with increased fuel requirements, demanding Indonesian society to harness alternative energy, one of which is biofuel.
