Abstract

This study analyzes the influence of exchange rates, inflation, and interest rates on shrimp exports in Indonesia from 1999 to 2019 using multiple linear regression. The research findings indicate that the exchange rate and inflation positively influence shrimp exports, whereas the interest rate negatively impacts them. The regression coefficient for the exchange rate is 10.015, which indicates that each depreciation of the rupiah by 1 rupiah per year will increase shrimp exports by 10.015 tons per year. Conversely, the interest rate has a negative regression coefficient of -3519.690, suggesting that each 1% increase in interest rates will reduce shrimp exports by 3.519,690 tons per year. Inflation has a positive regression coefficient of 3.333,168, indicating that each 1% increase in inflation will increase shrimp exports by 3.333,168 tons per year. However, only the exchange rate shows a significant relationship, with inflation and interest rates not significantly impacting shrimp exports. The model's coefficient of determination is 58.3%, meaning that approximately 58.3% of the variation in shrimp exports can be explained by the exchange rate, inflation, and interest rates. This study provides crucial insights for policy makers and the shrimp industry in considering the factors affecting shrimp exports for the creation of applicable policies and strategies.

This research was conducted on 105 respondents using a purposive sampling method. The method in this study is quantitative with multiple linear regression and using the SPSS 25 program. From the results of the t test, the price discount variable has a not significant positive effect on impulse buying and the in-store display variable has a significant positive effect on impulse buying at Irian supermarkets, Medan city. There is a low (weak) relationship between price discount and in-store display variables as a whole on impulse buying in Irian supermarkets in the city of Medan, namely 15.1% and the rest is influenced by other variables not examined in this study

Abstract

The aim of this research is to elucidate the influence of government expenditure, domestic investment, and foreign investment on the Gross Domestic Product (GDP) in Indonesia. This research employs an explanatory research type, utilizing a quantitative approach with secondary data. The focus of this research is the development of the Gross Domestic Product in Indonesia from 2000 to 2020. Linear multiple regression analysis is utilized for data analysis in this study. The result of the F-test indicates that government expenditure, domestic investment, and foreign investment collectively significantly affect Indonesia's Gross Domestic Product. Partially, government expenditure, domestic, and foreign investments have a positive impact on GDP; however, only government expenditure exerts a positive effect, while domestic and foreign investments have a negative influence. Based on these data analyses, the government should pay more attention to the realization of government expenditure to exert a more notable effect on the Gross Domestic Product, and also maintain the stability of investment, both domestic and foreign, to support future government planning with the available capital.
