Abstract

When using the Systematic Literature Review (SLR) technique, the research objective is to examine the impact of PBB and BPHTB on PAD. This research identifies, assesses, and synthesizes previous relevant works bringing together many sources in Sprott-approved journals on this topic. The results of this research show that, although at different levels, PBB and BPHTB make significant contributions to PAD in various regions in Indonesia. Increasing revenue from the PBB and BPHTB sectors is one strategy to increase PAD. However, a number of regions still experience difficulties in maximizing revenue from these two tax categories, including low effectiveness and PAD contributions which are in the low to medium range. In addition, this research found that PBB has a significant and beneficial influence on regional economic growth, although the impact of  BPHTB on this cannot yet be determined. The overall results of this research highlight the important role of PBB and BPHTB in increasing PAD and regional economic growth, so it is important for local governments to maximize management and increase revenue from these two types of taxes.

Abstract

This study aims to determine the optimal portfolio composition for primary consumer sector stocks in Indonesia during the 2020–2022 period, a time marked by high market volatility due to the COVID-19 pandemic. The analysis focuses on two stocks: PT Sumber Alfaria Trijaya Tbk. (AMRT) and PT Indoritel Makmur Internasional Tbk. (DNET). Using a quantitative descriptive–explanatory approach, the research includes the calculation of returns, variance, covariance, correlation, portfolio formation with the Markowitz Model and Single Index Model, as well as performance evaluation using the Sharpe Ratio, Treynor Ratio, and Jensen’s Alpha. The results show that AMRT offers higher average returns but with greater volatility, while DNET provides more stable returns with lower risk. The negative correlation between the two stocks (-0.319) enables effective diversification. The minimum-risk portfolio is obtained with a composition of 13% AMRT and 87% DNET, achieving a risk level of 10.68%, which is lower than the risk of each individual asset. Meanwhile, the best-performing portfolio based on the Sharpe Ratio is achieved with a composition of 30% AMRT and 70% DNET, offering optimal efficiency between return and risk. These findings reinforce the relevance of Modern Portfolio Theory in the Indonesian market context and provide strategic recommendations for investors to optimize asset allocation through measurable diversification.
