Islamic Astronomy Software : Digital Falak

Android is a linux-based operating system for mobile phones such as smartphones and tablet PC. Android provides an opensouce platform for developers to create their own applications for use by a variety of mobile devices.

Android already has some changes starting from android version 1.1 to the current android version 7.0. Of course with the development and improvement of android, the users were involved to develop various applications, both for personal and public purposes.

Android development is also up in the field of Islamic Astronomy. The "Digital Falak" app is one of the applications of Islamic Astronomy based on android, created by Ahmad Tholhah Ma'ruf published in the Playstore. The application is made in 2012 but in 2014 this new application is released. And in the middle of 2015 this app is officially uploaded in Playstore and can be used by many people especially for android users. Download this app in Playstore or in Digital Falak Web
.

Digital Falak Icon

Digital Falak contains several programs, there is Prayer Time, Qibla Compass, Hijri Calendar, Location Data, and Istiwak Time.

Local Prayer Time and Masehi Calendar

• Prayer Time.
Prayer Time in this application displays some data that is: the time of salat Zuhr, Asar, Magrib, Isha, Imsak, Dawn (Fajr), Thulu, and Duha. Available in 2 time, local time and istiwak time. We can also adjust the criteria and ihtiyath time in the setting menu. The prayer time in this application also has the alarm for remember us to do pray.

Istiwa Prayer Time and Hijri Calendar

• Hijri Calendar
The Hijri calendar in Digital Falak uses the two-book method of making it by using "Fathu al-Rouf al-Manan" and "Nurul anwar". Users just choose which books to use in the settings menu. there is also Masehi/public Calendar

Qibla Compass and Rashdul Qibla Calculation

• The Qiblah Compass
The Qiblah compass is quite easy to understand especially for who do not know the calculation of the Islamic Astronomy, because in it already has a Qibla Compass program, the direction shown by the compass will face the qibla, but this application has a weakness, because the base of the compass using magnetic sensor, then this application is very influential with the magnetic force that surrounds the user.
The Qibla Compass feature also requires magnetic sensors, so for mobile devices that do not have magnetic sensors can not use this feature. Instead there is also a feature Rashdul Qibla calculation, the calculation of the time where the shadow of the Sun will face the qibla.

Location Data Menu

• Location data
Location data in digital falak can be used to find the latitude, longitude, height of place, time zone and place name according to the position in GPS. This data is always updated and can also update by using the internet after the phone is connected to the internet.

This application also there is a version of the website, we will discuss in the next article.

Google Qibla Finder

One of the requirements of a valid prayer is facing the Qibla, which is a Ka'ba in Mecca, Saudi Arabia.

To determine the direction of qibla there are many ways, ranging from traditional to modern. Some use a very traditional tool like a stick, some use simple tools but still have a fairly high accuracy such as Mizwala and Istiwaaini, some also use modern tools as well as Teodholite and Total Station. Use of some of these ways may still cause difficulties if who will determine is a beginner.

Nowadays has come a very useful technology for all human activity, that is smartphone. These benefits also apply to the determination of Qibla direction. Lots of users or developers who already take advantage of this technology, a lot of software / program direction of the Qibla is made for smartphones, let alone android smartphone. There are currently around 500 to 600 Qibla direction apps in the playstore, but if we are going to download the app it will be a bit complicated and confused, especially as the accuracy of the apps itself is untested.

But Google has responded to that, Google has presented a web-based qibla direction program that is highly compatible with smartphones especially android and has a very nice interface. The program is called Google Qibla Finder.

To use it we just need to open the browser, any browser through our smarphone, then slide to the site Google Qibla Finder then we will be taken to the Google Qibla Finder page.

Then please note that the GPS position must be in a state of luminous, so that our android can read the coordinates of where we are. In the next step we will choose the interface language we want, then press the Let's Go!

Then Google Qibla Finder will directly calculate, measure the direction of Qibla and apply it to a map which is the location where we are.

If we flip smartphone towards the front, then the interface will turn into a camera and the line appears which is the direction of our place qibla. We can directly mark the direction of Qiblah on our floor through the line that is in our smartphone camera.

Very practical without having to calculate and bring a tool to measure the direction of Qibla. Can we use wherever we are.

Note: There are some things to watch out for, smarphone must support multiple sensors, such as gps, compass and motion sensors, other than that the camera conditions must also be in normal. For the last step I can not exemplify because my camera is in error.

Good luck!
