Abstract

Waqf is one of the acts of worship in Islam. Through waqf, Muslims can set aside a portion of their wealth for the benefit of the community, especially for the construction and maintenance of mosques. Masjid Fathur Rahman is one of the mosques located in the Binjai area, North Sumatra. This study developed a mobile-based waqf application for Masjid Fathur Rahman using the Extreme Programming method. The aim is to facilitate waqf donations and improve the efficiency of fundraising. The application development is made with two types of applications: a web application for mosque administrators and a mobile application for waqif. The success achieved by this application is inseparable from the advantages of the Extreme Programming method, which ensures a fast and structured application development process, increasing transparency and accountability in waqf management. As a result, the application created can be completed quickly and the application runs well so that the waqif can carry out waqf through the mobile waqf application.

Abstract

Poly Aluminum Chloride is a chemical used to reduce water turbidity. Poly Aluminum Chloride will agglomerate dirt in water into larger particles so that it settles more easily. The amount of coagulant added to the water must be precise so that the turbidity of the water can be suppressed to the maximum. To find out the optimal dose, a jar test procedure was carried out. The jar test was carried out by adding coagulants with different variations. The jar test will give results on how variations in the amount of coagulant affect the turbidity level of the water. In water with a turbidity of 25.2 NTU, the optimum dose of PAC coagulant used was 30 ppm. With this dose, the PAC coagulant discharge injected into raw water at a water treatment plant is 56,0747 ml/s.
