The usage of alternative fuel as a substitute of oil fuel for transportation sector in developed countries has been commonly implemented in order to decrease crude oil consumption, where in a few years back, the crude oil price is constantly increasing. In addition, global warming issue becomes one of reasons that motivate many countries to switch for a cleaner energy usage. As a country that has a relatively big reserve of natural gas, its appropriate natural gas could minimize subsidized oil fuel and also financing country＇s burden if Indonesia is optimizing the usage of energy resources. This paper will discuss about the background of gas fuel usage for road transportation sector in Indonesia, review of alternative fuel usage, the gas fuel usage status in Indonesia and gas usage recommendation for land transportation sector in Indonesia based on other countries experiences.

There is an increasing interest in India, to search for suitable alternative fuels that are environment friendly. Thisled to the choice of Mahua Oil (MO) as one of the main alternative fuels to diesel. In this investigation, MahuaOil Biodiesel (MOB) and its blend with diesel were used as fuel in a single cylinder, direct injection and compressionignition engine. The MOB was prepared from MO by transesterification using methanol and potassiumhydroxide. The fuel properties of MOB are close to the diesel and confirm to the ASTM standards. From the enginetest analysis, it was observed that the MOB, B5 and B20 blend results in lower CO, HC and smoke emissionsas compared to diesel. But the B5 and B20 blends results in higher efficiency as compared to MOB. HenceMOB or blends of MOB and diesel (B5 or B20) can be used as a substitute for diesel in diesel engines used intransportation as well as in the agriculture sector.

The phytohormone ethylene plays essential roles in regu- lating plant growth and development. Understanding the mechanism of ethylene biosynthesis, signal transduction, and downstream responses is of great importance to frame the entire processes of plant growth. Genetic and biochemical approaches were applied in recent years to help establish an approximately linear ethylene signaling pathway.

Dwindling supply and unpredictable price fluctuations of fossil fuels have necessitated a renewed worldwide search for alter- native fuels. Plant cell walls, rich in cellulose and hemicellulose, are actively pursued for their use in production of second-gen- eration biofuels. It has been envisioned that degradation of these carbohydrate polymers to their sugar monomer subu- nits （saccharification） will provide necessary substrates for their yeast-mediated fermentation to ethanol.

As global warming caused by greenhouse gases grows (GHGs) into a global environmental threat, carbon dioxide emissions are drawing increasing attention in these years. Among all emission sources, transportation is a major contributor to climate change because of its high dependence on fossil fuels. The International Maritime Organization (IMO) has therefore been promoting the reduction of fuel usage and carbon emissions for container ships by such measures as improving shipping route selection, shipping speed optimization, and constructing clean energy propulsion systems. In this paper, a review of the impact of carbon dioxide emissions on climate change is presented;the current situations of carbon dioxide emissions, decarbonizing methods, IMO regulations, and possible future directions of decarbonizing in the maritime transportation industry are also discussed. Based on the result, it is found that in the case that non intelligent ships still occupy the vast majority of operating ships, the use of new energy as the main propulsion fuel has the defects of high renewal cost and long effective period. It is more likely to achieve energy conservation and emission reduction in the shipping industry in a short period of time by using intelligent means and artificial intelligence to assist ship operation. .
