Based on data analysis proved that during 20152060, the number of Muslim population increased rapidly by increasing 70%, which is included converts in South Korea. The developments of Islam in South Korea characterized by the growing mosque of Seoul, Itaewon Mosque Islamic Center. The main constraint factor for Korean converts is there is still no prayer guide in Hangeul feature. Constraints experienced by converts, most important is prayer. The Korean Muallaf Center is an application that helps converts to include wudu, prayers, and easy-to-understand religious worship. The purpose of this research is to help converts to understand the guidelines of Islam with Hangeul, so that they can practice it. The methodology of this research is with literature study, application design, implementation, and evaluation of application usage. The results of this study are the Korean Muallaf Center Applications that have been used by Muallaf Korea.

Limitations and shortages of fresh water often occur problems especially for coastal communities, port areas and other areas with minimal water supply. The need and limitations of fresh water can cause distribution which is hampered due to lack of monitoring and distribution in the field, so that the distribution and distribution are evenly distributed. The purpose of this study is to overcome the problems that occur by designing and simulating tools that regulate the distribution of fresh water. The system works when the water flow sensor calculates the flow of water that passes through it and after reaching the maximum capacity previously set, the solenoid valve will automatically stop the distribution of water, so that every citizen who has the right to receive fresh water will get according to his daily allowance. In designing the simulation design there are several obstacles to the unavailability of several sensors needed, such as water flow sensors and solenoids for which we make alternative solutions by making logic C ++ algorithm in Arduino Uno R3.

The distribution of air in the Klender Flats in East Jakarta is still not evenly distributed, so that some of the residents of the flat are increasingly lacking in water. Remembering water is the main need in everyday life. To overcome the problems that occur, a tool is made that can measure air flow and regulate the distribution of air using Arduino Uno. This tool uses a device consisting of a solenoid valve and a water flow sensor that is sent to Arduino Uno. water flow sensor will calculate the amount of air that has been used and after reaching the maximum capacity the solenoid valve will flow air distribution in accordance with the maximum capacity of each family head (KK). To implement the tool into the system, the writer uses C programming language and for websites using PHP. The use of water will be monitored every one hour and the system will send data to the database for retrieving necessary monitoring data on the website in graphical form.
