Economic growth is a measure of the success of economic development of the country, thus realizing the economy well be the main goal. Several variables such as the level of investment, ZIS, and inflation are used in this study. The purpose of this study is to examine the influence and relationship of investment, ZIS, and inflation on economic growth in Indonesia. This research method using a quantitative approach. The Data used is secondary data in the form of time series. This research method using a quantitative approach. The method of analysis using the model of Vector Autoregression (VAR), followed by the model Vector Error Correction Model (VECM), if there is cointegration. Data testing is done with the help of software Eviews 7 and Microsoft Excel 2010. The results of the study found that the variable ZIS and inflation have an effect on long-term GDP. Variable mutual funds conventional and sharia does not affect the long-term GDP. Variable mutual fund conventional, Islamic mutual funds, ZIS, and inflation does not influence short-term economic growth. GDP responds positively to shocks that occur in a mutual fund conventional, sharia mutual funds, and ZIS. GDP responds negatively to the shock on inflation. Variable inflation gives the largest contribution to GDP, then mutual funds conventional and ZIS as well as the last sharia mutual funds.

This paper discusses productive waqf and the uniqueness of the application of productive waqf management in a pesantren (Islamic boarding school). Furthermore, the standardisation of the law used in the implementation of the productive waqf, which includes al-Qur'an, Hadits, fiqh rules, and aqwal al-'ulama, must be examined in order to reach a conclusion on the implementation status. There are many unique things to analyze in the implementation, such as the use of the institution fund, which is oriented to develop cash waqf, and the exictence of the waqf board, which becomes the highest decision maker. Because all of the pesantren's assets become waqf property, the highest leader is no longer on the foundation but on the waqf board.

Waqf, an Islamic form of giving, has a significant impact on poverty alleviation. Gontor Islamic Boarding School is a prominent Indonesian educational institution that has successfully evolved Waqf education. Gontor prompted Waqf in 1958 to aid not just Islamic education but also the reduction of poverty. This study aims to analyse the poverty alleviation through the Waqf based business unit in Pesantren as implemented by Gontor Pesantren. The successful of poverty alleviation much depends on the unit influences by human resources improvement, Business units waqf and waqf Gontor Pesantren. Gontor manage a lot of waqf fund under 281 business units in around 22 branches of Gontor. This study employs hybrid qualitative and quantitative approaches (focus group discussions (FGD) and interviews (appearance inquiry questions). This study uses the Analytical Hierarchy Process (AHP) and the Structural Equation Model for data analysis. The number of expert respondents used to answer the first research objective was seven, whereas the number of respondents used to answer the second research objective was one hundred fifty. The results of the study indicate that the most promising large-scale business unit at the Gontor Islamic boarding school is a bottled water company with an eigenvector value of 0.36. This is due to the fact that the required capital is not excessively high because main production factor to obtained water at no cost. In addition to being marketed within Islamic boarding schools, the products are also distributed outside of Islamic boarding schools, resulting in a substantial amount of revenue. The most promising small-scale waqf based Business Units is Laundry, with an eigenvector value of 0.39, because every student need laundry services. Furthermore, the capital is not excessive because it serves the surrounding community in terms of laundry. The development of human resources had an effect on the Waqf of the Gontor Islamic boarding school, while the Waqf based Business Units had an effect on increasing human resources and the waqf of the Gontor Islamic boarding school then the waqf of the Gontor Islamic boarding school had an effect on alleviating poverty. In addition, the model of the waqf based Business Units of the Gontor Islamic boarding school seeks to alleviate poverty by offering employment opportunities to the pesantren surrounding community. Simultaneously, Pesantren Gontor helps promote health by providing health facilities at Yasfin Hospital and by giving educational scholarships at the Pesantren Gontor. This study contributes to the creation of a theory of productive waqf based on Islamic boarding schools that can alleviate poverty by supplying implicit evidence. In addition to the implicit policy, this research can bring fresh ideas for the development of Waqf based Business Units within Islamic boarding schools or Pesantren in Indonesia.
