The study of night sky brightness is useful not only for the purpose of astronomical observations (quality of dark sky, time of eclipse, etc.), but also related to the multi-aspect of pollution, climate change, social, health, tourism, biology, and prayer times. In this seminar and short discussions will present some monitoring results and measurement of the night sky brightness based on the portable photometer Sky Quality Meters from several locations, especially from the Bosscha Observatory from 2011. The sky brightness is known to vary on various time scales, from daily to monthly (Moon phase), seasonality, until the solar cycle (11 years). The results of the initial determination of the dawn time can also be determined from changes in the brightness of the sky.
