Abstract

Increasing on electricity price by Indonesian Government in 2001 by 17.47% and 2002 by 24% not only has negative impact on industry sectors but also on agricultural sectors. This paper aims to analysis impact on agricultural sectors performance with using a Recursive Dynamic Computable General Equilibrium (CGE) Model, namely “INDOF model”. The simulation indicates both in the short run and long run increasing on electricity price will reduce industry output, household consumption and employment in agricultural sectors. Besides that the policy will increase price of agricultural product. The negative impacts except household consumption are higher in the long run than that in the short run.

Abstract

White tea is a new product in Indonesia’s tea industry. It is a product developed by Research Institute for Tea and Cinchona in order to revive Indonesia’s tea industry. White tea has uniqueness in its relatively high price and high market demand that not affected by its high price. The increasing number from Indonesia’s middle class income could also become white tea’s new potential consumer because they put quality and health first than the price. White tea’s high price and demand attract new players in this industry. The appearence of new competitors make this in-dustry more competitive. That’s why it’s necce-sary to find a way to win the compettion and to keep the domination in the white tea industry through strategic formulation. There were two steps in strategic formulation used to produce the strategies. The first is analyzing the com-pany environment using internal factor evalua-tion (IFE) and external factor evaluation (EFE). The second is using internal and exter-nal (IE) matrix and strength weakness oppor-tunity and threat (SWOT) analysis. IE matrix showed the position of company using infor-mation from IFE and EFE. SWOT analysis resulted strategies using information from the company’s strength, weakness, opportunity, and threat. IFE and EFE showed that the company has strong internal power and good respond to external factors. IE matrix showed that com-pany is in grow and build stage. IE matrix and SWOT analysis showed that the alternative strategies for the company are market pene-tration, market development, product develop-ment, forward integration, backward integ-ration, and side integration.

Abstract

ABSTRACTThe objective of this study is to analyze the price transmission of Gayo Arabica coffee from farmers to exporters. This study utilizesECM (error Correction Model) to investigate price transmission based on monthly price data in farmer and exporter level from Januari 2008 until December 2014. The result showed that price transmission test ECM-EG model showed that in short term, the price transmission is assymetric and symetric in long term.The symmetrical price transmission between farmers and exporters in the long term, showed that there was no misuse of market power, Therefore, price changes that occur at the farmer level in the long term were transmitted perfectly towards exporter. Asymmetric price transmission in the short term is commonly caused by cost adjustment factors and marketing agency behaviors in the pricing mechanism and the performance of each level / marketing agencies. Therefore, the need for setting prices of Gayo Arabica coffee, especially at the producers (farmers) level and the government's role in monitoring the price according to the quality of coffee, and inform the development of the market price (the local and the world) to the farmers.

Abstract

An 29% increased on fuel price on  March 1st, 2005 has several implications on Indonesian economy. It includes micro and macroeconomics performance of Indonesian economy.  Using Recursive Dynamic Computable General Equilibrium (CGE) Model, namely “Poverty Indonesian Model”, the simulations show that an increase of fuel price tends to reduced household and industry demand for fuel (oil refinery). Reducing demand also happen although an increase of fuel price following which the compensation fund on health and education sectors. Furthermore, wage of unskilled labor also decline. The purchasing power and welfare of households will be reduced because the households also face the increasing prices of commodities. From Macroeconomic side, an increased of fuel price decline has no significant impact on GDP and decline a household consumption and land rent. The inflation rate will around 3% after and before compensation program.

Abstract

PT Berdikari (Persero) was transformed into an Animal Husbandry State Owned Company (SOE) in 2012 through the letter of State-Owned Enterprises Minister Number S-211/D1.MBU/2012 to support Government’s policies on providing animal food supply. This business transformationchanges core competencies from trading agribusiness commodities (rice, sugar, meat, platantion commodities, fertilizer, insurance, etc.) to animal husbandry. It becomes corporate transformation phase that cause financial performance anomalies. This study aims to identify the effect of business transformation towards financial performance of PT Berdikari (Persero) using statistical hypothesis testing by T-test to explore the existence of financial performance impact before and after business transformation practice. Based on State-Owned Enterprises Minister Regulation Number 1000/MBU/2012 about SOE performance assessment, there are eight indicators for assessing SOEs’ financial performance: Return on Equity (ROE), Return on Investment (ROI), Inventory Turn Over, Colection Period, Cash Ratio, Current Ratio, Total Turn Over and Capital to Total Assets Ratio. The result of hypothesis testing with 95percent degree of significance found that there are differences of ROE and Inventory Turn Over PT Berdikari (Persero) before and after transformation. Company profit was decreased and operating expenses was increased. Low level of sales revenue drives ROE, especially after business transformation. This low level of sales caused Inventory Turn Over to increased since inventories in the warehouse was cumulated.

Abstract

The manufacture and characterization of the lithium bus Composite (oxalate) borate with the addition of magnesium chloride (LiBOB/MgCl2). Electrolytes as a media transfer ion battery, plays an important role in the charge-discharge process of lithium ion batteries. The basic ingredients used in the study are lithium hydroxide (LIOH), Borid acid (H3BO3), Our acid dehydrate (H2C2O4 • 2H2O) and magnesium chloride hexahydrate (MgCl2 • 6H2O). The method used in this research is solid state reaction or known as solid-solid method. Based on the results of the XRD characterization, shows the peaks of LiBOB experiencing a shift after being added with 2.5%; 5% and 7.5% MgCl2 • 6H2O, in addition it also raises new peaks of magnesium. While the spread of the material is blown the sample appears evenly with the SEM-EDX test, however there are some elements that are experiencing clotting. And the FTIR test showed a change in the frequency of each mass increase of MgCl2 • 6H2O, but did not cause peak changes in each sample. In the EIS test results, obtaining a low electrical conductivity value, due to agglomeration of the material after the addition of elemental magnesium that is ionic. Thus also causes the diffusion of ions to lower.

Abstract

Sub-surface analysis has been conducted to find out the lithology which includes the structure, the type of rock and the thickness of the geothermal layer of geothermal resources by using the geoelectric configuration method of Wenner-Schlumberger in Kalompie Hamlet, Galung Village, Barru sub-District, Barru District. The working principle of the geoelectric method is performed by injecting an electric current to the ground surface through a pair of current electrodes and measuring the potential difference with another pair of electrodes. The research was conducted in three trajectories with a trajectory length of 105 m and a spacing of 7 m electrodes. The result of the data interpretation was obtained by three materials that is sandy soil with resistivity value 0,095 - 4,05 Ωm have thickness 1 - 12 m, tuffed sandstone with resistivity value 4,05 - 39,7 Ωm having thickness 10 - 14 m, with a resistivity value of 39.7 - 547 Ωm with a thickness of 5 - 15 m, this rock is suspected as a rock cover on Kalompie hot water source area because it has a difficult nature to pass water (impermeabel). The geological structures of fault, anticline and syncline are not found in this research because the measurement path does not cut or pass through the path of geological structure.
