Coffee is an important commodity in Indonesia with high economic value. In Ulu Belu District, coffee distribution through long channels causes high distribution costs, so supply chain management (SCM) is needed to improve efficiency. This study aims to measure the cost efficiency and effectiveness of coffee distribution using qualitative descriptive analysis method. The results showed that coffee marketing efficiency in Channel I amounted to 11.98%, and Channel II amounted to 11.92%, both classified as efficient. Delivery accuracy was also high, with Channel I reaching 98.89%, while Channel II was 85.83%. Channel II is more cost-effective despite Channel I being more effective in delivery. Cost-efficiency is important because coffee is a perishable product, and weather-related delays are rare.

This study aims to determine the effect of fintech, the amount of money in circulation, interest rates and economic growth on the analysis of digital economic trends on monetary policy in Indonesia. There are four variables in this study, namely fintech, the amount of money in circulation, interest rates and economic growth. The analysis method used is Vector Autoregression with the Impluse Response Function test or abbreviated as IRF and the Forecast Error Variance Decomposition test commonly abbreviated as FEVD, stationarity test, cointegration test, lag structure stability test and optimal lag length test. There is a contribution from each variable to the variable itself and other variables, according to the results of the Vector Autoregression study with a lag basis of 2. In addition, the results of the Vector Autoregression analysis show that the past variable (t-1) contributes to the current variable both to the variable itself and to other variables. The results of the analysis show that there is a reciprocal relationship between the variables. By using response function analysis, we can see if there is a response from other variables to changes in one variable in the short, medium, or long term. In addition, we know that the stability of all variables is formed in the short, medium, and long term. According to the Variance Decomposition Analysis, factors such as Fintech and Money Supply contribute the most to the variable itself. However, other variables that have the greatest influence on the variable itself and are supported by other variables in the short, medium, and long term are economic growth and interest rates are most influenced by Fintech.

The money supply can affect other economic variables, such as output and prices, create stability in the economy and help achieve the ultimate goal of monetary policy, namely the stability of inflation and exchange rates.  The level of the exchange rate by the monetary authority must be kept stable because an unstable exchange rate, especially one that experiences a sharp depreciation, can have financial crisis implications. This research approach was associative/quantitative research. The data used in this study are secondary data taken and processed from Bank Indonesia (BI) and the Central Statistics Agency (CSA) from 2013-2023 (11 years). Based on the results of regression analysis shows that the variable money supply, exchange rates, and interest rates simultaneously affect the inflation variable. Based on the results of regression analysis shows that the variable money supply has a positive and significant effect on inflation. Based on the results of regression analysis, the exchange rate variable has a negative and significant effect on inflation. Based on the regression analysis, the interest rate variable has no statistical effect on inflation.
