Abstract
The dynamics of the area of Lake Beratan is important to know the impact of population development and changes in land use changes that occur around the lake. In addition, sedimentation originating from river flows and household waste is a concern which can cause silting and pollution of Lake Berata water. Therefore, the aim of this research is to monitor the area of Lake Beratan periodically using a fast and efficient method. The method used to support this is remote sensing technology, especially through visual interpretation by paying attention to the key elements of interpretation and digitizing it on screen. The results show that there are differences in areas from 1990, 2000, 2010 and 2020. The largest area obtained when digitized in 2010 was 377.42 hectares and the smallest area in 2020 was 363.98 ha. The entire digitization process cannot be separated from knowledge of interpretation in digitization and recognizing the conditions of the Beratan Lake area. Based on this, it is possible for remote sensing imagery to be used in monitoring lake area manually and to obtain more accurate results of course combined with color composite analysis.
