Abstract

This study aims to analyze the performance and determine the optimal asset allocation of a stock portfolio in the Indonesia Stock Exchange (IDX) by rigorously applying the Markowitz Mean-Variance Model. This research is a quantitative study that utilizes historical return data from a selection of highly liquid blue-chip stocks over a five-year observation period. The methodology involves calculating the expected return, variance, and covariance matrices, followed by quadratic optimization to identify the most efficient portfolios, specifically the Global Minimum Variance Portfolio (GMVP) and the Tangent Portfolio. The findings reveal that significant benefits from diversification are achieved due to moderate positive correlation among the selected assets, resulting in a distinctly curved efficient frontier. The optimal portofolio, characterized by the highest Sharpe Ratio, consistently demonstrates a superior risk-adjusted return profile compared to investing in any single stock asset. This study concludes that the Markowitz Model is highly effective in structuring investment strategies in the IDX, validating the importance of covariance analysis for risk mitigation and strongly aligning with the prudent investment principles of Islamic economics (ghair gharar).

Abstract

The transformation of the local agricultural economy in Kutalimbaru Pasar X faces challenges due to the low added value of banana products, caused by a simple distribution pattern. Farmers sell their harvest in its raw form to middlemen without any processing or collective management. As a result, the bargaining power of farmers is weak, and profit distribution is uneven. This study aims to analyze the implementation of the Islamic economic approach in the transformation of the local agricultural economy. The method used is descriptive qualitative, involving field observations, interviews with farmers, and literature review. The research findings show that strengthening farmer institutions, implementing transparent pricing mechanisms, and post-harvest processing can increase the added value of products and improve profit distribution. The application of Islamic economic principles, such as justice, cooperation, and accountability, can establish a fairer and more sustainable village economic system. This economic transformation also impacts the increase in farmers' income and strengthens the economic resilience of the community-based society. By integrating Islamic economic principles, it is hoped that the local agricultural sector can develop more productively and provide equitable benefits for all parties involved in the production and distribution processes.
