Abstract

This study aims to examine the role of zakat as an economic instrument that can encourage household consumption, increase income equality, and support macroeconomic stability within the framework of Islamic economics. As a form of wealth redistribution, zakat has an important function in distributing part of the muzakki's wealth to the mustahiq, thereby strengthening the purchasing power of low-income groups who tend to have higher marginal consumption. This increase in consumption then contributes to aggregate demand growth and expands economic activity. In addition, zakat acts as an automatic stabilizer that maintains the consumption capacity of vulnerable communities during economic slowdowns, thereby reducing the risk of a decline in aggregate demand and maintaining overall economic stability. This study uses a qualitative method with a literature review approach to examine various scientific sources related to zakat, consumption theory, and the concept of income distribution. The findings of the analysis show that the success of zakat as an economic instrument is greatly influenced by professional and transparent governance, as well as targeted distribution, particularly through productive zakat programs that encourage the independence of mustahiq. Zakat also has significant potential in strengthening the Islamic economic structure oriented towards justice through reducing inequality and improving community welfare. Thus, optimizing zakat management is a strategic effort to build an inclusive, sustainable economy that supports the empowerment of vulnerable groups.

Abstract

This study aims to analyze the influence of Gross Regional Domestic Product (GRDP), unemployment rate, and poverty on the Islamic Human Development Index (I-HDI) across 38 provinces in Indonesia during the 2023–2025 period. Secondary data were sourced from Statistics Indonesia (BPS) and analyzed using panel data regression with the Fixed Effect Model (FEM) approach. The results indicate that simultaneously, the three independent variables significantly affect I-HDI with an R2 value of 93.66%. Partially, GRDP and unemployment have a positive and significant impact on I-HDI. The positive coefficient of unemployment presumably represents the characteristics of developed regions with a concentration of educated unemployment who maintain high human capital. Meanwhile, the poverty rate has no significant effect on I-HDI. This insignificance indicates the resilience of Islamic human development against material shocks, which potentially driven by the existence of informal social safety nets from Islamic philanthropic instruments (ZISWAF). This study recommends strengthening inclusive economic policies targeting human capital quality and optimizing the integration of socio-religious instruments.

Abstract

This study aims to examine the effects of inflation, exchange rates, and global oil prices on the Jakarta Islamic Index (JII) in Indonesia. The approach used in this study is a quantitative approach utilizing secondary time-series data for the period 2016–2025, consisting of 120 monthly observations. The analytical technique used was multiple linear regression, with first-difference transformation to address the issue of data nonstationarity. The results indicate that inflation does not have a significant effect on the JII. Conversely, the exchange rate was found to have a significant negative effect, suggesting that a depreciation of the rupiah tends to dampen the performance of the Islamic stock index. Meanwhile, global oil prices have a significant positive effect on the JII. Collectively, these three variables account for 29,34% of the variation in the JII. These findings are expected to serve as a useful reference for investors and stakeholders in understanding the dynamics of macroeconomic factors in the Islamic capital market.

Abstract

Penelitian ini bertujuan untuk menganalisis peran wakaf produktif sebagai instrumen kebijakan fiskal Islam dalam mendukung pembiayaan pembangunan sosial, khususnya di sektor pendidikan, kesehatan, dan pemberdayaan ekonomi masyarakat di Indonesia. Penelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan riset kepustakaan, menganalisis literatur akademis, laporan resmi dari lembaga wakaf, dan dokumen kebijakan terkait pengelolaan wakaf produktif. Hasil penelitian menunjukkan bahwa wakaf produktif memiliki potensi besar sebagai sumber pembiayaan sosial jangka panjang yang berkelanjutan karena sifat permanen aset wakaf dan kemampuannya untuk menghasilkan arus dana yang stabil. Namun, optimalisasinya masih terhambat oleh keterbatasan kapasitas manajerial nazhir, rendahnya tingkat digitalisasi, lemahnya integrasi regulasi, dan kurangnya literasi masyarakat. Studi ini menyimpulkan bahwa wakaf produktif dapat berfungsi sebagai mekanisme pembiayaan publik alternatif yang efektif jika didukung oleh profesionalisasi nazhir, penguatan regulasi, inovasi digital, dan kemitraan multi-sektor.This study aims to analyze the role of productive waqf as an Islamic fiscal policy instrument in supporting social development financing, particularly in the education, health, and community economic empowerment sectors in Indonesia. The research employs a qualitative descriptive method with a library research approach, analyzing academic literature, official reports from waqf institutions, and relevant policy documents related to productive waqf management. The findings indicate that productive waqf has substantial potential as a sustainable long-term source of social financing due to the permanent nature of waqf assets and their ability to generate stable funding flows. However, its optimization remains constrained by limited managerial capacity of nazhir, low levels of digitalization, weak regulatory integration, and inadequate public literacy. The study concludes that productive waqf can serve as an effective alternative public financing mechanism if supported by the professionalization of nazhir, strengthened regulations, digital innovation, and multi-sectoral partnerships.
