Abstract

This research is aimed at proving whether there is an influencing relationship between the independent variables (Interest Rates) and (Infrastructure) on the dependent variable (Domestic Investment). This research method uses panel data regression analysis by combining two data from time series with cross section. From the test results for individual correlations, it was found that the Interest Rate Variable correlation did not have a partial/individual significant effect on Domestic Investment (PMDN). While the Infrastructure Variable on Domestic Investment (PMDN) has a significant influence partially/individually.Furthermore, joint testing between all independent variables on the dependent variable. (Interest Rates and Infrastructure) together have a significant effect on the dependent variable Domestic Investment (PMDN). Based on this research, it illustrates that low bank interest rates and good infrastructure will be able to encourage increased domestic investment which will ultimately be able to increase GRDP, people's income and people's welfare in Banten province. Therefore the role of the government in terms of improving the quality of infrastructure, especially roads and intervention on interest rates (credit) will greatly assist domestic investors to become entrepreneurs.

Abstract

Delta Graha Makmur faces challenges in selecting steel plate raw material suppliers due to a manual system that focuses solely on price, resulting in 30% delivery delays, inconsistent quality, unreliable supplier dependency, as well as increased costs and production disruptions. This study aims to develop an ANP-TOPSIS-based supplier selection system to evaluate structured criteria such as quality, timeliness, price, and reliability. The objectives include: (1) formulating recommendations for the best suppliers with TOPSIS scores >0.8, (2) reducing production delays by 40% within three months post-implementation, and (3) developing a training module for the procurement team. The research method is carried out in four stages over 12 weeks: ANP modeling through interviews, performance data collection from five suppliers, TOPSIS analysis and simulation, as well as system implementation and training. The expected outcomes are improved supplier selection efficiency and reduced negative impacts on production.
