“…Further such efforts have led to the recent historic announcement on the change in prayer time for Islamic followers in Malaysia. This project was led by the country's Department of Islamic Development (JAKIM), with strong support from local astronomers due to the need to calculate the sun's depression angles of 19° and 20° below the horizon to determine the start of prayer time 2 .…”

“…This distortion will then lead to the inconsistent determination of Subh prayer times. The inconsistencies of Subh prayer times determination due to light pollution are demonstrated by Bahali et al (2018), Faid et al (2018), and Hassan & Abdel-Hadi, (2015.…”

Astrotourism is tourism that uses astronomy as its main attraction. As astrotourism requires astronomy phenomena, it requires a location free from light pollution. As some have posited locations free from light pollution as one of the cultivating elements for maintaining sustainability, Astrotourism can be used to achieve sustainability. Sustainability can be put under the umbrella of Maqasid Syariah and halal tourism. It is thus of utmost importance to demonstrate the unique capabilities of Malaysia as a viable Astrotourism attraction and how it can help achieve the goal of sustainability, both of which are the objectives of this research. Two methods are employed in this study; the first is to identify potential Astrotourism sites using the dark sky database, light pollution mapping and Garstang formulation of light pollution. The second method is comprised of identifying the cultivating elements of sustainability. Through this method, three potential Astrotourism sites could enhance the notion of sustainability, including sustainability from the economic, wellbeing and biodiversity aspects and, more importantly, sustainability towards the holistic practice of Islam. This demonstrates the encompassing benefit of Astrotourism towards sustainability and its development potential in Malaysia.

“…Sementara itu, algoritma lain yang dapat digunakan untuk menghitung posisi matahari adalah Algoritma Meeus (Meeus, 1998) Sementara itu, penelitian di Malaysia menyimpulkan bawah sudut elevasi matahari di bawah ufuk untuk waktu subuh adalah 20 derajat (Nor & Zainuddin, 2012). Hasil penelitian ini berbeda dengan hasil penelitian terbaru oleh tim Jabatan Kemajuan Islam Malaysia (JAKIM) (Malaysia, 2019), yang menyimpulkan -18 derajat dan penelitian Kasim et al yang mendapati nilai -17 derajat di bawah ufuk (Bahali et al, 2018). Penelitian serupa juga pernah dilakukan oleh Khalid Shawkat di enam negara (Amerika, Pakistan, Inggris, Karibia, Australia, dan New Zealand) dan menyimpulkan sudut depresi -13.5 hingga -14 derajat.…”

The inclusion of prayer time is one of the valid requirements of prayer as explained in the Qur'an and hadiths of the Prophet (s). The Fajr prayer schedule issued by Wahdah Islamiyah is interesting to review because it is different from the official prayer schedule issued by the Ministry of Religious Affairs, Republic of Indonesia. This difference can have implications for the validity or absence of Fajr prayers and fasting performed by Muslims based on the schedule. This study aimed to analyze the method of determining the Fajr prayer schedule issued by Wahdah Islamiyah. This research is qualitative descriptive research through library study methods and content analysis. The results showed that Wahdah Islamiyah compiled its Fajr prayer schedule with a high-accuracy contemporary accounting method using VSOP87 algorithm. The location of markaz da'wah in Makassar City was chosen as the coordinate point of the calculation of the position of the sun. Wahdah Islamiyah's Fajr prayer schedule uses a sun altitude of 18 degrees below the horizon by adding a two-minute of iḥtiyāṭ. Based on the calculation, the Fajr prayer schedule of Wahdah Islamiyah has been accurately used in the Makassar City area
