Penentuan Awal Waktu Subuh Menggunakan Kamera DSLR dan Metode Moving Average

Abstract

The existence of technology, especially optics and digital, that can be used with similar settings anywhere so it can be implemented by anyone and become a new standard for the determination and visual view of early dawn time seen in the field. Digital cameras could take periodically so that they can produce a series of images according to time and show the difference in the sky when the transition of dawn time and be an option for the beginning of dawn time in the world evidentiary. The results of this study showed that there was a difference at the beginning of dawn time according to the Ministry of Religion with the results of processed imagery using the MA method. The results of the imagery successfully showed the beginning of the change in the sky at dawn with the appearance of a significant change in pixel value. This study found that the initial results of dawn time on the observation date were at the time of the sun at a dip of -17° 07' 12". The observations using SQM with data processing using the MA method also gave the same results as image processing from DSLR cameras

Penentuan Waktu Malam Menggunakan Sky Quality Meter Dengan Pendekatan Moving Average

“…Penelitian waktu senja juga masih tetap berlangsung, baik menggunakan pengamatan mata secara langsung dan instrumen pengambilan citra maupun non-citra seperti Sky Quality Meter secara manual ataupun dengan sistem otomatisasi. Keberadaan teknologi ini juga menjadi langkah lebih maju untuk dapat memastikan awal waktu senja yang sesuai dengan kriteria pada Hadist dan fenomena langit yang terjadi saat terjadinya perubahan siang dan malam tersebut dengan lebih akurat (Putraga et al, 2022). Pengukuran kecerahan langit saat malam sangat penting untuk menentukan tingkat polusi cahaya di tempat tertentu (Butar-Butar et al, 2020), dan dalam penelitian ini digunakan untuk mengamati perubahan langit dari terang ke gelap.…”

Developing and Testing a Cooling System for CMOS in DSLR to Minimize Noise in Astronomical Image and Incorporating a Sky Quality Meter

“…The use of DSLRs as a tool to conduct research in astronomy has also been done several times. In some studies, DSLRs can be used to measure the brightness of the sky [6][7][8][9]. DSLRs have also been used to collect photometry, spectroscopy and radiometry data [10][11][12][13][14].…”
