Abstract

Coal utilization including its processing for an alternative energy is quite large in Indonesia and absolutely necessary. Especially on coal with low calorific value like lignite, at handling with direct combustion as in conventional coal power plant is an environmentally friendly manner because its emission contains harmful substances NOx and CO. Approching with clean coal technologies, gasification, emissions of harmful substances into the environment can be reduced. This gasification process, coal is converted into syngas which is an intermediate product that can be directed into various types of alternative fuels such as methanol. Development of efficient and low cost DME synthesis from syngas produced from gasification of coal has been our interest, in particular development  of low cost catalyst which is shown by Low Pressure Fixed Bed Reactor. In this research scheme, we develop the catalyst using Co-precipitation method and Copper based catalyst. In this preliminary study, the DME synthesis of catalysts based on Methanol catalyst has been modified by combined it with HZSM-5 as dual catalyst. This process will perform DME production in one step Fixed Bed Reactor. micromeritic reactor at mild operating condition. The results of modified catalyst to Sud-Chemie/NaHZSM-5 Si/Al 25 showed that DME synthesis at 30 bar and 270oC reach a good conversion, up to 0.9% and predicted still able to increase. Keywords: low rank coal, DME synthesis, low cost catalyst, low pressure fixed bed reactor

Abstract

Utilization of coal as well as its processing as an alternative energy is quite large in Indonesia and absolutely necessary. Especially on coal with low calorific value such as lignite, handling with direct combustion as in conventional coal power plant is an environmentally friendly manner because its emission contains harmful substances NOx and CO. With clean coal technologies (such as gasification), emissions of harmful substances into the environment can be reduced. This gasification process, coal is converted into syngas which is an intermediate product that can be directed into various types of alternative fuels such as methanol.Development of efficient and low cost methanol synthesis from syngas produced from gasification of coal has been our interest, in particular development  of low cost catalyst which is shown by Low Pressure Fixed Bed Reactor. In this research scheme, we develop the catalyst using Co-precipitation method and Copper based catalyst.. In this preliminary study, the synthesis of catalysts based on CuZnAl has been performed and tested in once trough process micromeritic reactor at mild operating condition. The results show that methanol synthesis at 20 bar and 270oC reach a good conversion, i.e. 1.15% of methanol at Molar Ratio (Cu:Zn / CuZn: Al2O3): 4: 3: 1. These results have been compared to commercial catalysts on the same conditions which reached 0.26% of methanol .  Kata Kunci : low rank coal, methanol synthesis, low cost catalyst, low pressure fixed bed reactor

Abstract

The purpose of this research is to examine whether individualism-collectivism dimension (beliefs, values and norms) positively related with organizational citizenship behavior dimension (interpersonal helping, individual initiative and loyal boosterism) in an accounting environment setting. Structural Equation Model (SEM) are used to analyze data. The sample consists of 365 accounting college students. The results showed that individualism-collectivism‟s dimension positively related with organizational citizenship behavior dimension. This result supported the previous research conducted by Moorman and Blakely (1995).

Abstract

The major purpose of this study is to investigate the association between earnings management after IPO and stock returns with investors sophistication as a moderating variable. Institutional ownership is used to proxy investors sophistication.The JSX (Jakarta Stock Exchange) listed companies and issuers of IPO from 1990 to 2002 period is used as samples. The companies which institutional ownership >/ 40% consist of 75 IPOs. Earnings management was detected with Instrumental Variable Approach (Kang and Sivaramakrishnan, 1995).This study provides an evidence that issuers report unusually high earnings management around 1Po (two years before and five years afier IPO. Issuers used mean reversing strategy in two years before IPO period (income decreasing) for preparing earnings management in the next period (income increasing). Furthermore, this study documents there is no association between earnings management and stock returns with investorssophistication as moderating variable.Keywords: IPO, Earnings Management, Instrumental Variable Approach, Stock Returns, Investors Sophistication.

Abstract

This study provides information on predictive ability of annual earnings and cash flow from operation numbers. We obtained a sample of 44 BEI listed companies and 352 observation, year-end firms from 2001 to 2009. We find that both cashflows and earnings numbers have substantially predictive ability for future cashflows. Furthermore, this study documents that earnings numbers have more predictive ability for future cashflows than cashflows and the result are robust.Keywords: Earnings, Cashflows, Earnings and Cashflows Prediction.
