Abstract

This research undertakes a meticulous examination of the Indonesian e-commerce industry, aiming to unravel the intricate patterns governing consumer behavior within this rapidly evolving digital landscape. Employing an extensive dataset and cutting-edge data analysis methodologies, this study discerns pivotal trends that have engendered transformative shifts in Indonesia's e-commerce sector.

This pronounced transition underscores the remarkable adaptability of businesses to the digital milieu, thereby accentuating the significance of a digitally oriented business paradigm. Furthermore, this research brings to light the prevailing predilection among non-formal e-commerce enterprises, whose revenues predominantly dwell below the IDR 300 million threshold. Notably, the Cash on Delivery (COD) method remains the preeminent payment mechanism. These observations illuminate the structural underpinnings of the market and consumer payment proclivities, thereby exerting a discernible influence on pricing strategies and payment processing mechanisms adopted by enterprises. Moreover, the study delves into the transformative effects of the COVID-19 pandemic, which have expedited the digital metamorphosis of both consumers and e-commerce enterprises. This acceleration has ushered in a new epoch characterized by novel opportunities and concomitant challenges within the e-commerce domain. In summation, this research furnishes a multidimensional and academically rigorous perspective on the Indonesian e-commerce landscape, furnishing actionable insights indispensable for businesses and policymakers alike. The comprehension of these evolving trends is indispensable for strategic formulation and policy calibration, enabling adept navigation of the dynamic e-commerce milieu.

Investment decisions that have a direct impact on corporate value, focus on decisions that reflect future investment opportunities, such as introducing new products, expanding existing products, replacing replacement of equipment or facilities, research, development, and exploration. The results of the deterministic analysis show that the coefficient of determination (R^2) is 0.955, indicating that only about 95.5% of the variation in firm value (book value) can be explained simultaneously. by investment decisions, financing decisions and dividend policies. This means that the company's risk is not directly affected by these variables. Furthermore, the analysis results show that the coefficient of determination (R^2) is 0.041, indicating that only about 4.1% of the variation in firm risk can be explained by variations in investment decisions. investment, financing decisions and dividend policy.

Abstract

This study aims to analyze the relationship between various assumed economic variables and exchange rate fluctuations of the Rupee against the US dollar. The variables considered include the logarithmic difference of the consumer price index of Indonesia and the United States, the logarithmic difference of the money supply of Indonesia and the United States, the logarithmic difference of the gross domestic product of Indonesia and the United States, the logarithmic difference of the Indonesian and US interest rates and the logarithm of the Indonesian balance of payments. The data analysis results show that only the difference between the logarithm of the gross domestic product of Indonesia and the US and the difference between the logarithm of the interest rates of Indonesia and the US have a significant influence on the change in the exchange rate of Indonesia rupiah. The R-squared of 61.6% shows that the observed variation in the dependent variable can be explained by the independent variables, while the remaining 38.4% is influenced by other factors. The conclusion of this study is that the difference in change in the logarithm of gross domestic product and the difference in the logarithm of interest rate have a significant impact on the volatility of the rupee exchange rate.

Abstract

This study analyzes the influence of rural poverty on school enrollment rates in Indonesia. Using time series data for the period 1998-2021, the analysis model used is simple linear regression. The study revealed that school enrollment rates and rural poverty levels in Indonesia fluctuate throughout the year. The estimation results indicate that rural poverty has a negative effect on school enrollment rates at both elementary school, middle school and high school levels. Therefore, efforts to increase school participation in Indonesia must be in line with efforts to reduce rural poverty levels.

Abstract

This study examines the impact of accessibility and creativity on the financial performance of Micro, Small, and Medium Enterprises (MSMEs). Accessibility encompasses financial literacy and inclusion, both of which significantly influence the financial outcomes of MSMEs. Creativity enhances competitiveness and financial performance, particularly in product development and marketing. A quantitative research approach with a survey design was employed to gather data from 200 MSME operators in Indonesia. A questionnaire was used to assess accessibility, creativity, and financial performance. The results from multiple linear regression analysis revealed that accessibility and creativity positively affect the financial performance of MSMEs. Access to capital, technology, and training are key factors that improve business performance. Additionally, creativity in product development and marketing strategies contributes to financial growth. The findings suggest that enhancing accessibility and fostering creativity should be prioritized to strengthen MSMEs' competitiveness in the market. Policies that promote better access to financial resources and training for MSME operators are essential to ensuring the sector's sustainability and success.
