Abstract

This research is important to provide a clear picture of Indonesia's economic dynamics and to support better decision-making in economic policy. Increased domestic investment is not enough to drive overall economic growth, and foreign investment is also not in line with the increase in domestic investment due to a mismatch between domestic investment and expected economic growth outcomes. The purpose of this study is to analyze the role of foreign investment and domestic investment on Indonesia's Gross Domestic Product (GDP). This study uses time series data from 2014-2023. The results of this study indicate that Foreign Direct Investment (FDI) does not have a significant positive effect on Indonesia's Gross Domestic Product (GDP). Although it shows a positive direction, the effect is not significant, so increasing foreign investment is still needed to drive the growth of Indonesia's Gross Domestic Product (GDP). Domestic Direct Investment (DDI) has a significant positive effect on Indonesia's Gross Domestic Product (GDP). This indicates that PMDN significantly contributes to GDP growth in Indonesia, with a stronger role than foreign investment. Simultaneously, foreign investment and domestic investment had a positive and significant impact on Indonesia's Gross Domestic Product (GDP) from 2014 to 2023. This indicates that although domestic investment had a partial negative impact, both simultaneously still made a positive contribution to economic growth.

Abstract

This study aimed to analyze relationship beetween Non Performing Loan (NPL), inflation, lending rate, and rate of unemployment. Credit by conventional banks always carry Non Performing Loan. The more amount of credit granted, will carry the higher risk. Indonesian Banking system has been implementing selective credit policy. This selectivity seen from conditions of credit requirement for different categories. This article use Autoregressive Distributed Lag Error Correction Model by Engle Granger to analyze the relationship on the short term and long term. The result showed that in long run, inflation, lending rates, and rate of unemployment has a significant effect in NPL working capital loans, but inflation and rate of unemployment doesn’t have significant effect in NPL investment loans. In the short term,inflation has no effect on both NPL investment and NPL working capital, and rate of unemployment has a significant effect in NPL working capital loans in short term.   Key Words: NPL, Investment Loans, Working Capital, ECM

Abstract

The underground economy in border regions represents a complex phenomenon shaped by regulatory gaps, limited access to formal economic systems, and high transaction costs in legal trade. This study analyzes the dynamics of informal cross-border trade along the Indonesia–Timor-Leste border, focusing on North Central Timor (TTU) Regency and the Oecusse Enclave. Employing a qualitative descriptive approach, the research draws on field observations, semi-structured interviews, and thematic analysis to demonstrate that underground economic activities function not only as a survival strategy but also as an informally institutionalized, socially organized economic ecosystem. The findings reveal that price disparities, weak supervision, and limited institutional capacity collectively drive communities’ dependence on illicit trade. A comparative analysis of similar cases from international border regions highlights the need for policy responses tailored to local contexts. The study recommends strengthening bilateral cooperation, adopting surveillance technologies suited to regional capacities, and implementing community-based economic empowerment programs to facilitate the transition toward an inclusive and sustainable formal economy.

Abstract

This comprehensive research investigates the intricate relationship between macroeconomic factors and stock market performance, specifically focusing on the Indonesia Stock Exchange Composite Index (IHSG) and the Nikkei Stock Average. Employing a robust quantitative approach, the study emphasizes key variables such as inflation, exchange rates, interest rates, GDP growth, and oil prices, utilizing regression analysis to unravel unique patterns within the Indonesian and Japanese markets. For IHSG, significant negative correlations with inflation highlight its impact on purchasing power and corporate profitability. The non-significant relationship with the Bank Indonesia Interest Rate (BI Rate) emphasizes market resilience to interest rate fluctuations. The significant negative correlation with the Rupiah underscores the pivotal role of currency stability. Additionally, the non-significant relationship with oil prices suggests a limited influence on IHSG movements. Turning to the Nikkei, non-significant relationships with inflation, the Bank of Japan (BOJ) Rate, GDP, exchange rates, and oil prices underscore the diverse factors at play. These findings offer valuable insights for investors, policymakers, and researchers, enriching the understanding of the multifaceted influences shaping the relationship between macroeconomic conditions and stock market dynamics in Indonesia and Japan. The study contributes empirically rich insights, addressing gaps in existing literature and paving the way for informed decision-making in the complex landscape of global financial markets.

Abstract

This research examines the influence of domestic and external macroeconomic factors on stock market volatility in Indonesia, particularly the Jakarta Composite Index (JCI). While stock market volatility has become a global concern, there remains a research gap regarding the impact of regional global factors—such as neighboring countries' stock indices—on JCI volatility. The main objective of this research is to analyze the effects of inflation, exchange rate, and trade balance as domestic factors, alongside the Singapore stock index (Straits Times Index) and Thailand stock index (Stock Exchange of Thailand) as external factors, and S&P 500 and foreign exchange reserves as control variables, on JCI volatility over the period 2014–2023. The study employs the Autoregressive Distributed Lag (ARDL) method using monthly data. The results show that in the long term, the exchange rate and the SET index have a significant effect on JCI volatility, while in the short term, only the exchange rate shows a significant impact. Other factors do not demonstrate a consistent significant influence. These findings highlight the importance of exchange rate stability and regional stock market dynamics in influencing domestic stock market fluctuations.

Abstract

Digital transformation has become a strategic urgency for KBMI IV banks in improving efficiency, competitiveness, and performance stability amid increasingly competitive and technology-based banking industry competition. This study aims to analyze the effect of mobile banking, internet banking, and ATMs on the profitability of KBMI IV banks in Indonesia for the period 2012–2023. The study uses a quantitative approach with the Fixed Effect Model panel data regression method. Profitability is measured using Net Profit Margin (NPM), with control variables in the form of size, Loan to Deposit Ratio (LDR), and BI Rate. The results show that mobile banking and internet banking have a significant positive effect on NPM, while ATMs have no significant effect. The variables of size and BI Rate have a significant positive effect, while LDR is not significant. These findings indicate that digitization can increase profitability when integrated with optimal fund collection and distribution strategies. Therefore, targeted, measurable digital transformation management that is aligned with core banking activities is needed to support long-term performance sustainability.

Abstract

The study, which aimed to analyze the use of chemical fertilizers and pesticides using the Cobb-Douglas production function approach and their reallocation to increase the income of vegetable farmers and prevent land degradation, was conducted in Sumberejo Village, Batu City, Indonesia. Data were collected from 138 pakcoy (Brassica rapa), celery (Apium graveolens), and red chili (Capsicum annuum) farmers through interviews using a questionnaire. The relationship between input and output was analyzed by regression with the Cobb-Douglas production function. Data validity, reliability, and classical assumption tests were performed to ensure the goodness of fit regression model. Furthermore, the F test and t-test were applied to analyze production response to chemical fertilizers and pesticides. This study revealed that the modeled regression equation is appropriate, where R2 = 0.827-0.933. Vegetable production gives a different response to the use of chemical fertilizers (TSP, Urea, and NPK) and pesticides. Increasing this chemical in pakcoy and celery farming is possible, but it needs to be considered because it has no significant effect on increasing production. The productivity of these two types of plants is relatively high. Farmers need to compare the costs of adding these inputs to additional income and the possibility of land degradation. Chemical fertilizers and pesticides have been excessive in red chili farming, so productivity is very low. There are indications that the land has been degraded, but to be sure, a study is needed on the chemical content of the vegetable fields in Sumberejo Village and the optimal use of chemical fertilizers and pesticides.
