Analisis Perubahan Fungsi Penggunaan Lahan Dengan Tinjauan Persentase Penutupan Vegetasi (Studi Kasus : Sub Das Rokan Kiri Stasiun Awlr Lubuk Bendahara)

---

ABSTRACT
The Rokan Kiri sub-watershed station AWLR (Automatic Water Level Recorder) of Lubuk Bendahara has experienced the development of land use from forests to plantations, agriculture and settlements. Changes in land use can result in floods and cause water availability to decrease every year. The decrease in water availability is due to the ability of the sub-watershed to respond to falling rain. The purpose of this study was to analyze PPV (Persentage of Vegetation Cover) in the Rokan Kiri sub-watershed AWLR Station of Lubuk Bendahara. Changes in land use were taken by digitizing landsat maps from 2012 to 2021 using the manual classification method in the Arcmap application. Changes in the area of permanent vegetation are then used to calculate the PPV value in each year of the study. The results showed that the PPV value in the sub-watershed has increased and decreased. The highest value was in 2014 with PPV value 96,19%. In 2021 the PPV value was 94,37% and also the lowest PPV value. The average PPV value is 95,37%. The Rokan Kiri sub-watershed at the Lubuk Bendahara AWLR station is still in the "very good" category, because the PPV value of the research obtained is more than 80%.
Keywords: Analysis of Changes in Land Use, (PPV), Sub-Watershed.
