<![CDATA[The quality of night sky conditions can affect the results of astronomical observations and the survival of wildlife, one of which is sea turtles. One of the causes of the declining quality of the night sky is light pollution. To identify a location's light pollution levels and the quality of the night sky, it is possible to measure the night sky brightness with the Sky Quality Meter (SQM). This research specifically focuses on assessing night sky conditions in Berau, an important sea turtle conservation area, through analysis of SQM. By conducting observation through the period May-July 2022, covering each of the different moon phase, the objectives of this research to quantify the brightness of the night sky in Berau, measured in magnitude per arc square (mag/arcsec2) to describe the characteristics of light pollution in Berau and interpreted on the Naked Eye Limiting Magnitude (NELM) scale and the Bortle scale. Based on the research results, the highest frequency probability distribution was observed from the value of the sky brightness level measured using SQM in Berau, with the highest value obtained at the new moon phase, 19.60 mag/arcsec2, the conversion value in NELM being 4.68, and in the Bortle scale, grade 7 with the suburban transition category. And for the lowest value obtained at the time of the full moon phase, 16.66 mag/arcsec2 with a conversion value in NELM of 2.26, and on the Bortle scale, it is in class 9 with the category of the inner-city sky.]]>
