ABSTRAK
Tujuan utama dari makalah ini untuk menguji secara empiris pengaruh zakat, Produk Domestik Regional Bruto (PDRB) perkapita, Upah Minimum Regional/Provinsi (UMP), dan inflasi terhadap tingkat gini rasio di 34 provinsi di Indonesia selama tahun 2018-2020.  Temuan penelitian ini menunjukkan bahwa distribusi zakat yang diproksikan dengan Indeks Kesejahteraan BAZNAS serta tingkat inflasi secara statistik tidak berpengaruh signifikan terhadap tingkat ketimpangan pendapatan di Indonesia. Sementara itu, tingkat PDRB perkapita dan UMP memiliki arah hubungan negatif dan berpengaruh signifikan secara statistik terhadap tingkat ketimpangan pendapatan di Indonesia. Penelitian ini memberikan rekomendasi kepada pengelola zakat untuk menciptakan dan mengembangkan program zakat yang mampu memberdayakan perekonomian mustahik sehingga mampu mengurangi tingkat kesenjangan pendapatan dalam masyarakat. Selain itu, seluruh pemangku kepentingan (stakeholders) harus bersinergi dalam upaya meningkatkan realisasi pengumpulan dana zakat di lembaga dengan melalui peningkatan literasi dan kesadaran masyarakat guna mengoptimalisasikan peran zakat dalam peningkatan kesejahteraan masyarakat.
Kata kunci: Indeks Kesejahteraan BAZNAS, Ketimpangan Pendapatan, Makroekonomi, Zakat.
 

ABSTRACT
The main objective of this paper was to empirically examine the effect of zakat, Gross Regional Domestic Product (GRDP) percapita, Regional/Provincial Minimum Wage, and inflation on the gini ratio in 34 provinces in Indonesia during 2018-2020. The findings of this study indicate that the distribution of zakat, which is proxied by the BAZNAS Welfare Index, and the inflation rate has no statistically significant effect on the level of income inequality in Indonesia. Meanwhile, GRDP per capita and Regional/Provincial Minimum Wage levels have a negative and statistically significant relationship to the level of income inequality in Indonesia. In order to lessen the degree of income inequality in society, this study offers recommendations to zakat managers on how to design and develop zakat programs that can strengthen the mustahik's economy. In addition, all stakeholders must work together in an effort to increase the realization of zakat fund collection in institutions by increasing literacy and public awareness in order to maximize the contribution of zakat to raising the welfare of mankind.
Keywords: Baznas Welfare Index, Income Inequality, Macroeconomics, Zakat.
