Deforestation is a serious environmental problem in the OIC countries. From 1990 to 2016 based on 2019 OIC Environment Report data, compared to other groups outside the OIC, the OIC deforestation rate reached >10% on average, which was much higher. The focus of this study examines the effect of economic growth, agricultural land, and trade openness moderated by population density on deforestation. This study uses a quantitative approach and a Moderated Regression Analysis technique with a sample of 15 OIC countries from 2010-2019 taken from the purposive sampling method. The test results clarify that economic growth and agricultural land have a significant effect on the rate of deforestation, while the effect of trade openness is not significant on the rate of deforestation. From the results of the moderating variable, only agricultural land which has a significant effect on deforestation is moderated by population density. These results confirm Kuznets' environmental theory and environmental externality theory, and can be used as material for the government's evaluation to reduce deforestation rates and maintain forest sustainability according to SDG's No.15 agenda by considering demographic aspects such as population density. This study is limited to the 15 OIC countries that are the research sample due to their high forest fluctuations. s evaluation to reduce deforestation rates and maintain forest sustainability according to SDG's No.15 agenda by considering demographic aspects such as population density.

Purpose This study aims to examine how muzakki (zakat donator) and mustahik (zakat recipients) collaborated to strengthen the fundraising capability in Islamic social finance institutions (ISFIs) during the COVID-19. Design/methodology/approach This study uses a descriptive qualitative method in conjunction with interview techniques. Interviews with muzakki of various professions were conducted, as well as data from field documentation, to develop a collaborative model of muzakki and mustahik in strengthening the fundraising capacity of ISFIs. Findings The findings indicate that muzakki employed as civil servants, BUMN (state-owned enterprises) employees and entrepreneurs continue to pay zakat through ISFIs and support mustahik, whereas muzakki affected by the COVID-19 pandemic reduce their zakat spending. Consequently, with the collaboration of mustahik and muzakki, a framework can be developed to strengthen the strategy for raising funds for ISFIs. By empowering mustahik with businesses, ISFIs can increase the collection of zakat funds. Research limitations/implications The collaboration model would strengthen ISFI's ability to raise Islamic philanthropic funds and optimize their management. The basis for the regulation is contained in Law No. 23 of 2011 which allows collaboration between institutions and other stakeholders. In addition, the role of ISFIs does not end with the collection and distribution of funds, they also maintain the muzakki and mustahik's cooperation, so a significant role is required in involving muzakki and mustahik for them to collaborate and synergize, as well as improving the quality of human resource from Amil (zakat collector) to implement the strategy. Originality/value Few studies have been conducted in collaboration with Muzakki and Mustahik to develop models or frameworks for strengthening fundraising capabilities in ISFIs. Most of these studies are illustrative. Through collaboration between Muzakki and Mustahik, this research establishes a new model for enhancing the strategy of Islamic social finance fund raising to establish a sustainable system for ISFIs.

This research aims to find out the effect of bank internal variabel and macroeconomics variabel toward islamic banks financial performance proxied by Return on Assets (ROA) simultaneously and partially. Bank internal variables consist of capital structure, operational efficiency, asset quality, and liquidity, while macroeconomics variables consist of inflation and real GDP growth. Methodology that used in this study is quantitative approach using panel regression as technique analysis. Sampel used 11 Islamic Bank in Indonesia regulated by Otoritas Jasa Keuangan and launched legally before 2014. Data collected from annual report 2014 until 2018 from each banks.

Tax revenue of Organization of Islamic Cooperation (henceforth OIC) countries has not reached the global average, and so has the financial inclusion. Notwithstanding this fact, few researchers have addressed the effect of financial inclusion on tax revenue in the context of Islamic finance while it is undeniably having significant connection to the real sector. Drawing on this crucial issue, the present study calls into the possible effect of Islamic banking financial inclusion on tax revenue in eleven countries of OIC membership consisting of Indonesia, Jordan, Kazakhstan, Kuwait, Malaysia, Nigeria, Oman, Pakistan, Saudi Arabia, Turkey, and the United Arab Emirates in the period of 2013 to 2019. The data were analyzed under the procedure of panel data regression using fixed effect model. The result depicted that Islamic banking financial inclusion, in terms of financial access and financial usage, had no significant effect on tax revenue of the OIC countries. This result is reasonable, since Islamic banking financial inclusion still requires massive promotion particularly by the OIC countries included in this study.  Hence, this study leaves an implication for OIC countries to foster Islamic banking financial inclusion as a crucial effort to increase the tax revenue, in which Islamic banks play a promising role for sharia-compliance-based financial transactions in the recent years.
