Abstract

As a traditional crop, coconut is a versatile plant (tree of life) and has an economic value that is good enough to be developed particularly in the context of community economic development. This study aims to determine the effect of input variables X1 (Wide Land), X2 (Labor Costs), and X3 (Cost Fertilizer) against the benefits of coconut farm in the district Padangsidimpuan Batunadua. Analytical model used is the Cobb-Douglas profit function with the help of Eviews v5.1 application.The results showed that simultaneous variables X1, X2, and X3 affect the benefits of coconut farm with F-stat is 1728,765. partially each variable as: X1 shows a positive and significant impact on profits by ilai tcount 53.811 and Prob. Of 0.000., X2 showed positive and significant influence on profits by the value of 21.503 tcount and Prob. Of 0.000., and X3 shows a negative influence to the value of -2.511 tcount and Prob. Of 0.0138. Furthermore, from the obtained values for the regression coefficient of 0.9834 X1 means any addition of land area per ha will increase the gain of 0.9864 rupiah per Ha, X2 of 0.9757 means that any additional labor costs / yields would increase the profit of  0.9575 rupiah and -0.0651 for X3 which means every addition 1 rupiah of fertilizer costs will reduce profits 0,0651 rupiah. From the analysis it can be concluded, that the coconut farm production and profits in Kecataman Padangsidimpuan Batunadua still can be improved by optimizing the use of variable inputs of fertilizer and land.

Abstract

Based on the ratio of market share of 11 commercial banks discovered the phenomenon gap of the period 2007-2011 where 11 commercial banks dominate the banking market predominantly in Indonesia, including four state-owned banks. This phenomenon has resulted in the banking market structure tends to form an oligopoly, it is obviously affecting the behavior of banks that have a dominant position to maintain supernormal profit, which is reluctant to extend credit with low interest tribes and not a reflection of efficient behavior that ultimately lead to the real sector can not run role in the economy because of factors hampered financing. And with the market conditions are 11 commercial banks were so dominant, which is feared if one bank's collapse could affect the performance of banks in a systemic and even disrupt the Indonesian economy in general. The objectives of this research to determine the form of the banking market structure and analize the influence of concentration market structure and Capital Adequacy Ratio (CAR), Non Performing Loan (NPL), Net Interest Margin (NIM), and Loan to Deposit Ratio (LDR) to Return on Asset (ROA) wich is as a proxy of Financial Performance Banking in 2007 until 2011 periods. The data in this study was collected from Indonesian Banking Directory of 2007-2011. The collected sample was 11 biggest commercial banks over the period from 2007-2011. The analysis model  was used to determine the shape of banking market structure by using CR4 concentration ratio (Four Concentration Ratio) on a share of the assets, the share of third-party funding (DPK) and the share of loans, that produce banking that shaped the oligopoly market structure moderate low or concentration oligopoly level IV, where four largest banks a dominate about 42% - 50% market share. The estimation of the Fixed Effect Model unknown  that concentration market, market share, Capital Adequacy Ratio (CAR), Net Interest Margin (NIM) and the Loan to Deposit Ratio (LDR) has a positive effect on profitability (Return on Assets ) as a proxy for the performance of the banking industry. And for the  Non Performing Loan (NPL) has a negatively effect on profitability (Return on Assets) as a proxy for the performance of the banking industry.

Abstract

This study aims to compare theinvestment on agriculture sector in Southeast Sulawesi. Data used are of annually, covering 1990-2009.  The analysis is undertaken by using a multiple regression.The result shows that the interest rate of credit, the Gross Regional Domestic Producton agriculturesector simultanaeously to give significant effect  to theinvestment on agriculturesector. The value of regression coefficient of the interest rate credit is negative, but the interest rate of credit does not provide a significant to the investment on agriculture sector. Meanwhile, the Gross Regional Domestic Product on agriculture sector has a positive relationship and has a significantto the investment on agriculture sector. The value of regression coefficientby 0,191 indicates that when the GRDP on agriculture sector increase by1 rupiahwill increase investment on agriculture sector by 0,191 rupiah, or when agriculture GRDP increased by 1% then will improve the investment on agriculture sector of 0,97%, or more easily can be defined that if the GRDP of agriculture sector increase, the investment of the agriculture sector will also be increase.
