Research data from the Center for Strategic Studies of Baznas on Zakat Mapping Potential Indicators (IPPZ), which analyzes the calculation of zakat potential based on sectoral and regional zakat objects, shows that Indonesia has the potential for zakat of IDR 233.8 trillion in 2019. However, only 3.5 percent of them can be managed. Therefore, Baznas has collaborated with fintech but it is not yet based on sharia. This study uses the Islamic Economic Research Method (Muamalah) with a descriptive normative approach. The results showed that the digitalization of ZISWAF through fintech was effective and the results exceeded the target. On the other hand, according to some scholars, several forms of fintech operations contain non-Islamic elements. Therefore, the Baznas agreement must explicitly state that fintech should separate ZISWAF funds from other fintech user funds so that they are not considered as float funds to be placed in BI; and do not utilize ZISWAF funds. Neither Baznas, muzakki, nor mustahik can benefit from depositing funds. Sharia fintech is a practical solution for UPZ Masjid to increase zakat inclusion. Unfortunately, Indonesia has no regulations related to sharia fintech.

<p>Batujai Reservoir locates in Batujai Village, Praya Barat, Central Lombok, West Nusa Tenggara. It is the primary source of irrigation water supply for agriculture in Central Lombok District with an area of around 3,235 ha. The problem is the bloom of water hyacinth weed (<em>Eichhornia</em> <em>crassipes</em>), which can cause reservoir water loss through evapotranspiration, affecting the amount of water reservoir available for the dry season. The objective was to identify the area of cover and estimate water loss through water hyacinth evapotranspiration for the period 2013 – 2017. This study used a descriptive method by analysis of secondary data which were meteorological data and landsat-8 satellite imagery. Evapotranspiration analyzes use CROPWAT 8.0, monitoring water hyacinth cover using landsat–8 satellite imagery processed using ENVI 5.3 and ArcGIS 10.4 software. The results show that the spatial distribution of water hyacinth can be detected and mapped accurately with an overall classification accuracy of 84.11% – 97.04% using Landsat 8 data, with a kappa coefficient of 0.80 – 0.96. The area of water hyacinth cover ranges from 38,400 m² – 2,158,500 m², with a cover area of more than 20%, causing water loss above 8,000 m³ day^-1, which occurred in April 2013, April 2015, April 2016, February 2015, May 2014, May 2016 and July 2016, in those months it was seen that the amount of water loss was greater. Therefore, it is needed to suppress the growth of water hyacinth, in maintaining reservoir water storage capacity to support a systems of sustainable agriculture.</p>

This research aims to determine the ability of andisol which is composited with TiO2 as a degrading agent of Rhodamine B dye. The composite was made by sonication and calcination. Each material was characterized by FTIR and XRD. Photodegradation was carried out under a UV lamp with variation of the degradation time for 1, 2, and 3 hours. While the pH variation was carried out at 3, 5, 7, and 9. The photodegradation results were tested using UV Vis spectrophotometer at wavelength of 552 nm. Based on these results, the optimum conditions for photodegradation at pH 5 with irradiation time of 2 hours was 39.55%.
