The exchange rate is the value of the currency of a country with the value of the currency of other countries, which used to make the international trade. This study aims to analyze the effect of BI Rate, money supply, inflation, foreign exchange tourism, exports and imports on the exchange rate in Indonesia. The analysis uses cointegration equation with Error Correction Model (ECM) method. This paper investigates the relationship between the dependent and independent variables in both the short term and long term. The estimation results show that in the short term, variables that affect the rupiah exchange rate on US $ in Indonesia are BI interest rate and exports. While in the long run, the independent variable effect on the exchange rate of the rupiah is the BI interest rates, money supply, and export also. Inflation, foreign exchange tourism, and import do not affect rupiah exchange rate either in short or long term. These results show that control the level of interest rates and the money supply as well as encouraging exports have a crucial role in controlling the exchange rate so that the economy will be in a stable condition.
This study aims to analyze the feasibility of a hydroponic business on a home industry scale. This research tries to respond to the rising hydroponic farming system, which allows it to be applied as an alternative to a home business. However, this development is not yet optimal for new entrepreneurs because the investment value is relatively high. Meanwhile, a business feasibility study is needed to justify that the high investment value is commensurate with the profitability generated from the hydroponic business. The feasibility study results indicate that the hydroponic business with a home industry scale has excellent profitability. However, despite having a good return ratio, the income generated is relatively small as the primary income. Therefore, there is a need for continuous development in the hydroponic business to increase the production capacity of the hydroponic system. Furthermore, further studies are needed regarding market acceptance of hydroponic products to ensure the company's sustainability. Nevertheless, this study has provided empirical evidence that the hydroponic industry has potential and financial benefits as an alternative to starting a home-based business.
