Abstract

Fluctuations in world crude oil prices significantly impact oil-importing countries like Indonesia. These fluctuations affect multiple sectors, including the import of consumer goods, which is vital for the domestic economy. In Indonesia, consumer goods are crucial for economic stability. Thus, understanding how oil price fluctuations influence imports is essential for policymaking. This study investigates the relationship between world crude oil price fluctuations and the import value of consumer goods in Indonesia over an extended period. A quantitative approach was used, treating world crude oil prices as the independent variable and the import value of consumer goods as the dependent variable. Linear regression analysis, supported by descriptive statistical methods, was employed to assess this relationship. The results indicate that world crude oil prices have a significant effect on the import value of consumer goods, with data showing near-normal distribution and low skewness and kurtosis, validating the model. However, positive autocorrelation in the residuals suggests the need for further analysis to ensure the reliability of the model. These findings offer important insights for policymakers on managing the economic impact of oil price volatility on Indonesia’s domestic market. Future research could explore additional factors, such as inflation or trade policy, that may influence this relationship, contributing to more effective economic strategies.

Abstract

Macroeconomics learning often faces challenges in conveying complex abstract concepts to students. This paper aims to optimise macroeconomic learning by integrating contextual case study approach and simple mathematical modelling. This educational service method involves training and mentoring students in analysing real cases of economic policy using mathematical models to improve their understanding and literacy of economic policy. The evaluation results showed a significant improvement in analytical skills and understanding of macroeconomic concepts, especially related to the impact of endid and monetary policies. This approach is recommended as an innovative learning model to improve the quality of macroeconomic education.

Abstract

Islamic microfinance institutions face complex challenges in data management and customer behavior prediction in the digital era. This study aims to optimize the Gradient Boosting algorithm with pruning techniques to predict customer collectibility. The analysis was conducted on data from 57 customers with 7 attributes from 2022 to 2024. The research methodology includes four stages: data collection, pre-processing, modeling, and evaluation. Pre-processing involves handling missing data, normalization, encoding, and feature selection. Modeling using XGBoost with and without pruning, followed by evaluation using accuracy, precision, recall, F1-score, confusion matrix, and ROC curve metrics. The results show an increase in model performance with pruning: accuracy increased by 0.70%, precision 0.60%, recall 0.80%, and F1-score 0.70%. This technique is effective in reducing overfitting and increasing model generalization. This research provides significant contribution in developing more accurate credit scoring system for Islamic microfinance institutions, improving credit risk management and customer service in Islamic microfinance sector. The findings help Islamic microfinance institutions optimize credit decision-making process and reduce risk in the digital era.

Abstract

The purpose of this study is to determine the types of protection provided by the government to microeconomic actors in Mandailing Natal Regency, namely farmers, fishermen, and street vendors, and the reinsurance they receive. This study uses a quantitative descriptive approach, which measures quantitative data and objective statistics through scientific calculations from a sample of survey respondents to determine the frequency and percentage of their responses. The results show that microeconomic actors face significant challenges, such as low incomes (farmers IDR 2.8 million/6 months, fishermen IDR 1.05 million/week, traders IDR 800,000/month) and minimal guidance and protection from the government. The study's conclusions underscore the urgency of more inclusive policies to empower microeconomic actors through guidance, protection, and access to capital, in order to strengthen the national economy. These findings enrich the literature on microeconomics by emphasizing the integration of Islamic and conventional approaches in economic development. Keywords: Microeconomics, Population, Protection.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) adalah penggerak roda perekonomian di Indonesia yang mampu menyerap tenaga kerja sekitar 97% dan berkontribusi terhadap produk domestik bruto (PDB) sekitar 57%. Oleh karena itu keberhasilan usaha UMKM akan berdampak baik juga terhadap perekonomian Indonesia. Penelitian ini bertujuan untuk mengetahui apakah modal usaha sebagai faktor internal dan pemberdayaan UMKM oleh pemerintah sebagai faktor eksternal berpengaruh positif terhadap keberhasilan usaha UMKM. Hasil yang diperoleh adalah modal usaha berpengaruh positif terhadap keberhasilan usaha dengan tingkat pengaruh sebesar 0,516 dan pemberdayaan UMKM berpengaruh positif dengan tingkat pengaruh sebesar 0,366. Modal usaha dan pemberdayaan UMKM secara simultan berpengaruh positif terhadap keberhasilan usaha UMKM sebesar 79,2%. Sementara 20,8% lainnya dipengaruhi oleh faktor lain di luar penelitian. Oleh karena itu, pelaku UMKM agar menaruh perhatian terhadap modal usaha yang harus terpisah dari keuangan pribadi dan program pemberdayaan UMKM oleh pemerintah saat ini agar tetap dilanjutkan dan dikembangkan lagi.Kata kunci:  Keberhasilan, Modal, Pemberdayaan, UMKM

Abstract

Per capita expenditure is an important indicator reflecting the purchasing power and welfare of a country or region. This study aims to describe per capita expenditure in North Sumatra Province at the district/city level and analyze the influence of population, minimum wage, and unemployment rate on per capita expenditure across all districts/cities in North Sumatra Province in 2022. This study uses a quantitative method with a cross-sectional data regression model, accompanied by tests for normality, multicollinearity, heteroscedasticity, autocorrelation, and hypothesis testing. The results of the analysis indicate that the minimum wage level has a significant effect on per capita expenditure, while population and unemployment rate do not. The results of this study are expected to serve as a reference for local governments in formulating policies that support increased per capita expenditure, which ultimately contributes to encouraging consumption and driving the regional economy.
