Abstract

The purpose of this study is to determine the projected value of Regional Domestic Product (GRDP) for the Indonesia-Malaysia (Nunukan) border region and also the difference in the value of GRDP for the Indonesia-Malaysia (Nunukan) border region for 2020–2022 with the projected GRDP value for 2023–2025 using least squares method. Data analysis used different test analyses in the SPSS 25 statistical application. The data used in this study is GRDP data at current prices and constant prices in the Indonesia-Malaysia border area (Nunukan) in 2012–2022. As for the results of this research, the projected GRDP value in 2023 is 35,984,230; in 2024, it is 38,382,804, and in 2025, it is 40,781,378 (GRDP data based on current prices). The projected value of GRDP in 2023 is 17,952,185; in 2024, it is 18,618,070; in 2025, it is 19,283,955 (GDP data at constant prices). The results obtained after conducting the t-test using the SPSS statistics 25 application are a significance value (2-tailed) of 0.227 > 0.05 (for GDP data at current prices) and a significance value (2-tailed) of 0.019 > 0.05 (for GRDP data at constant prices). So, according to the independent sample decision-making basis of the t-test, H0 is accepted, and Ha is rejected. It means there is no significant difference between the actual and forecast values (GRDP data based on current/constant prices). It happened because, in that year, a worldwide disease outbreak resulted in economic instability. It is because the government has made a policy regarding social distancing.
