PENGAMATAN FAJAR ṢĀDIQ MENGGUNAKAN SISTEM OTOMATISASI OBSERVASI FAJAR DAN SKY QUALITY METER STAND ALONE DI SULAWESI SELATAN (STUDI KOMPARATIF)
This journal will discuss the comparative effect of the brightness level of the night sky on ṣādiq dawn through observations using SQM Stand Alone and SOOF, as well as the accuracy of SOOF on ṣādiq dawn observations in South Sulawesi. The purpose of this study was to determine the comparative effect of the brightness level of the night sky on the appearance of ṣādiq dawn through observations using SQM SA and SOOF in South Sulawesi and to determine the accuracy of SOOF on ṣādiq dawn observations in South Sulawesi. The research used in this study includes quantitative research with a focus on field research. The research results in Bulukumba obtained a brightness value of 21.6 - 22.0 mpsas and with SOOF it produced a solar dip between -18.24° to. -19.18°. While SQM SA produces a solar dip in the range of -17.74° to -19.51°. Takalar Regency has a moderate brightness level, (20.4-21.8 mpsas). By using SOOF, which tends to be in the range of -15.1° to -18.4°. Meanwhile, using SQM SA produces solar dip at -15.1° to -18.6°. Makassar City has a sky brightness value of 14.9-15 mpsas. SOOF produces solar dip data at -9.1° sd. -13.4°. Meanwhile, SQM SA produces dip values between -9.9° to. -13.0°. The level of accuracy of SOOF in observing the dawn of ṣādiq in South Sulawesi after an independent t test analysis was carried out to find out the significance of the comparative data on the angle of sun depression at 3 locations between the SOOF and SQM SA recorded data found that the Sig value (one side and two sides) is 0.475 and 0.950 > 0.05. Based on these results it can be concluded that H0 is accepted and Ha is rejected, meaning that there is no significant difference between the average Subuh Dip results using the SOOF and SQM SA instruments. This proves that the SOOF tool is accurate based on field observations using a comparison method with a tool that has been recognized as accurate globally, namely SQM. So that SOOF is accurate with various approaches and its use can represent at least two other instruments, namely SQM and cameras
