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 CobbDouglas 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 Fstat 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 : Depreciation of the rupiah prompted Bank Indonesia raised SBI to strengthen the rupiah, inflation has a downward trend when the appreciation of the rupiah, and the movement of the exchange rate also change the position of the current account of Indonesia. This study aimed to determine the role and effects of changes in exchange rates, inflation, gross domestic product, interest rates and the current account balance for each variable. Data obtained from secondary data is exchange rate, inflation, GDP, interest rates and the current account data from 2000:1 up to 2010:4. The model used in this study is the econometric model by the method of Vector Autoregressive (VAR) that in their analysis the instrument has Impulse Response Function (IRF) and Variance Decomposition (VD). The results of this study concluded that (1) All variable giving each other random shock to other variables and response by each variable so as to achieve long-term equilibrium. This is shown on the estimation IRF test on each variable; (2) All variables are mutually contribute to other variables. It is shown by the results of estimation VD test, in which each variable contributed to other variables.

Abstract : Inflation expectations to be one of the main runway most economic agents in setting prices and wages, which in turn affect consumption and investment decisions. In relation to the aim of research is to look at the effectiveness of the path of inflation expectations by analyzing random kejutatan (shock) and the contribution of each variable to changes in another variable. The results of this study concluded that (1) all give each variable a random shocks to the other variables so as to achieve long-term equilibrium. This is shown by the results of the estimated IRF test on each variable, (2) all the variables together contribute to other variables as shown by the results of estimation VD test. From the estimation of inflation expectations can be concluded that monetary policy affects inflation
Abstract : The research was conducted to determine the effect of economic variables that can explain the change or variation in the rate of inflation in the Consumer Price Index (CPI) as the dependent variable. The explanatory variables (independent) were used as controls are SBI, the nominal interest rate spread (SBI) and the value of the rupiah against the U.S. dollar. Based on these results, according to the specific purpose of the model equations II, suggested economic actors can use SBI interest rate spread as an indicator of variations in the CPI inflation rate at intervals of 8 and 12 months, with a note that the obtained level of explanation has not shown that the optimal value.
