Prayer is one of the worship that must be done by all Muslims in this world. If you have entered prayer time, whether we are wherever we are as a devout Muslim it is obligatory to immediately do the prayer. No exception when we are visiting or traveling in a certain area. Therefore, it will be very helpful if there is an application that can find the location of the nearest mosque that can be accessed using a smartphone. Previously, there were similar applications but only accessible via the web. Then, using google maps actually can already find the closest mosque, but there are still shortcomings, namely location data displayed at some point is invalid (the location at certain points there is no mosque). So, the Sigoca Master application (Nearest Mosque Search Information System) in Semarang City based on Android is made to help all Muslims who are visiting or traveling in the City of Semarang. Geolocation and Haversine Formula are the methods I will use to build the Sigoca Master application. With these methods, it is expected that the application built can help find the location of the nearest mosque from the user's location.

Computers now have very high capabilities so they can be used virtualization. With computer capabilities that are high enough computer lab practicum and server administration can already be done on a pc or laptop that has virtualization applications installed. Network practicum and server administration that previously could only be done in the classroom, so with this technology it is expected that it can be practiced on a PC or personal laptop for each student, so that students are able to continue the practical scenario that has been given. Virtualization will use Hyper-V that already exists in Windows 7, Windows 8 and Windows 10. In the Hyper-V application 4 Windows servers will be installed, all of which will be installed and connected via Active Directory. All windows servers will be accessed using a computer and physical network through the Remote Desktop Connection application. So it is expected that with this study student will be able to practice outside the campus lab environment.

Experiments were carried out using the type and length of catfish fingerlings with a length of 3 cm to 5 cm. Fish seed count tool has been tested to catfish farmers in the village Siwarak Ungaran City.The trial results calculators fish seeds have difference of 3% of the calculated results Manual or accuracy of calculation results have fish reaches 97%, then a counter of fish seed is acceptable to be used by catfish farmers.

The increase in motorized vehicles in urban areas is followed by an increase in cases of motorcycle theft due to the lack of public awareness about the motorcycle security system. The intensity of motorcycle theft with its disclosure is still far in comparison. Crime will also increase, such as cases of theft of motor vehicles, especially motorbikes. Cases of motorcycle theft still often occur, this happens because there is still a lack of security systems contained in motorized vehicles that only use ignition. the existence of an alternative safety system is needed because the average key of a conventional motorcycle is easily penetrated by thieves.

Hydroponics are now increasingly in demand, should be checked regularly so that hydroponic plants thrive. Likewise, in Siliwangi Indah Hydroponics Semarang, which still uses manual methods, namely the absence of a device that detects nutrient water temperature and pH automatically and the absence of tools that can normalize nutrients automatically. Arduino Uno R3 can be used to detect temperature automatically with a temperature sensor DS18B20, and detect pH with a pH sensor. Then the sensor readings are sent to the farmer's cellphone with SMS Gateway. The sensor readings are also used to divert the flow of nutrients from the spare reservoir, so that the nutrients remain normal. So this tool can automatically measure the nutrient water temperature and pH and replace the main nutrients to the reserve nutrients. And the assessment obtained from experts on this tool gets a value of 3.6 and from the expert gets a value of 3.7. Hydroponic nutrition in this study is maintained normally and farmers always know the nutritional state. So that the hydroponic plants thrive and have maximum yields.
