Abstract

Asean Economic Community (AEC) was officially started on 31December 2015. The objectives of AEC were to integrate diversity ofAsean economy into a single market with 625 million people ofinhabitant. AEC is expected to be a new market force in Asean andimprove economic development of Asean member countries. AEC willallow a free movement of goods and services, skilled labors and flow ofcapital in Asean countries. However, implementation of the AECframework is not an easy task; Trade policies, mobility of workers,diversity on politic, social, and economy including rapid growth ofeconomic development in China are some challenges to fully integrateAsean countries in a single market of AEC. For Indonesia, AEC providesopportunities to enhance export of goods and services in Aseancountries. Therefore competitiveness of Indonesian products in the AECmarket should be improved. Based upon components of competitivessreported by World Economic Forum (2014), Indonesia was in the top 5among Asean member countries, except competitiveness on efficiency inlabor market that was in the lowest position.

Abstract

Green house gases (GHG) in the atmosfer increase rapidly as a result of human activities such as the use of fossil energy for industry, power, and transportation, as well as the change of land uses for settlement, crop estates, buildings and others. Increase of GHG on air will rise temperature up, and change climate on earth. Scientific evidence indicated that climate change is a serious threat and needs urgent action. An increase in temperature for 2o celcius may cause a severe disaster such as flooding along shore lines and small islands, extinction of 15% - 40% species, and decrease of 20% agricultural products. GHG emissions can be reduced in several ways among other things are by decreasing demand on goods and services that causes intensive emissions, and avoiding activities that change land uses i.e., deforestation, estate crop development and mining. Markets for carbon trading are available in Tokyo, New York, Chicago, and this market encourages efficient GHG emission reduction. REDD is another scheme of carbon trading. In this scheme carbon emissions reduction from the forests will receive incentive/compensation (in financial value). However, the scheme is still in a process of development in global negotiation. This paper highlighted and described background on climate change, efforts toreduce GHG emissions, REDD scheme and problems in its implementation.

Abstract

Plastic waste is one type of waste that would disturb the environment if it is not handled properly. Alternative treatment to solve this problem is by using pyrolysis technology that enable to convert plastic waste into fuel oil, charcoal, and non-condensable gas. The success of pyrolysis technology is influenced by several factors, including the type of reactor, the particle size, the processing time, and the temperature of the pyrolysis process. The purpose of this study was to determine the effect of temperature on the yield and the calorific value of plastic pyrolysis oil. Based on the experiments, increasing the temperature, the yield of the oil produced and calorific value will be higher. The yield and the highest calorific value generated for the pyrolysis process at a temperature of 400 0C, are 44% and 10,292 cal/ g respectively.
