“…Irawan and Sirait (2018)), the vegetation density class was divided into ve classes: the non-vegetation class with an NDVI value < 0.1, a low dense class with an NDVI value of 0.1-0.2, medium dense with NDVI values of 0.2-0.3, dense class NDVI value of 0.3-0.4, and high dense class with NDVI values of > 0.4.…”

Vegetation plays an important role in maintaining the environmental quality of urban areas. Increase in population and development of cities has led to land conversion with lesser vegetated areas. Land cover change analysis in urban areas is needed, especially for urban regional planning with green open space consideration. This research was conducted to analyze urban vegetation cover and its changes in two sub-districts of Medan between the years 1999 and 2019. Normalized difference vegetation index (NDVI) and change analysis were conducted in the research. The diversity of plant within this areas was observed. The results showed changes in vegetation cover areas in the mentioned years. In 1999, most of the areas were under a highly dense vegetation class while in 2019, they were under a low-density vegetation class. This indicates a decrease in vegetation cover due to changes to non-vegetation cover or land cover areas with less vegetation. There are a diverse of plants within the area such as paddy, cassava, corn etc and also many tree species. It is recommended to optimize the land by replanting in the area with no or less vegetation to maintain the environmental quality.

“…Based on the finding in the field and some references in the classification of NDVI [37,38,39], the vegetation density class was divided into five classes: the non-vegetation class with an NDVI value <0.1, a low dense class with an NDVI value of 0.1-0.2, medium dense with NDVI values of 0.2-0.3, dense class NDVI value of 0.3-0.4, and high dense class with NDVI values of >0.4.…”

Vegetation existence contributes to environmental quality in urban areas. The increase in population and development of cities has led to land conversion with lesser vegetated areas. Information on land cover change is needed, especially for urban regional planning with green open space consideration. The research aims to analyze urban vegetation cover and its changes in two sub-districts of Medan between the years 1999 and 2019. Normalized difference vegetation index (NDVI) and change analysis were conducted in the research. The diversity of plants within these areas was observed. The results showed changes in vegetation cover areas in the mentioned years. In 1999, most areas were under a highly dense vegetation class, while in 2019, they were under a lowdensity vegetation class. This finding indicates a decrease in vegetation cover as a result of increasing built-up areas. Within the vegetation cover, it was found many tree species and agricultural plants. Those vegetations existed in some areas: city parks, house yards, gardens, agricultural fields, etc. A special emphasis should be placed on riverside areas with less vegetation in order to provide a higher level of protection, particularly in the event of a flood. To increase the vegetated areas and maintain the environmental quality, optimizing the land by replanting in the area with no or less vegetation should be done.

“…Manfaat mangrove diantaranya sebagai penghasil bahan pelapukan yang merupakan sumber makanan penting bagi invertebrata kecil pemakan bahan pelapukan (detritus), yang berperan sebagai sumber makanan bagi hewan yang lebih besar, sebagai kawasan pemijah atau asuhan (nurse ground) bagi udang, ikan, kepiting, kerang yang setelah dewasa akan kembali ke lepas pantai. Juga penghasil kayu untuk bahan kontruksi, kayu bakar, bahan baku arang dan bahan baku kertas (pulp), pemasok larva ikan, udang, dan biota laut lainnnya, juga sebagai tempat pariwisata [9].…”

Telah dilakukan studi mengenai pengenalan pola reflektansi spektral sebagai indikator perubahan distribusi kerapatan mangrove menggunakan data time series citra Landsat 8, di daerah kawasan Teluk Benoa, Bali. Tujuan penelitian ini adalah untuk mengetahui distribusi kerapatan dan luas areal mangrove dari pola reflektansi spektralnya. Metode dan analisis menggunakan reflektansi spektral dan indeks vegetasi Normalized Difference Vegetation Index (NDVI). Hasil penentuan nilai reflektansi spectral menunjukkan bahwa, perubahan pola reflektansi spektral mangrove di Teluk Benoa dari tahun 2017-2020 mengalami penurunan dan kenaikan untuk setiap band-nya. Pola reflektansi band 5 dapat digunakan sebagai acuan terhadap pengurangan luasan areal mangrove, dimana semakin kecil nilai reflektansi pada band 5 dari tahun 2017-2020 menunjukkan pengurangan atau perubahan kerapatan mangrove di tahun tersebut semakin besar. Berdasarkan data sebaran citra indeks vegetasi NDVI pada tahun 2017-2020 diperoleh tutupan luas per kategori dimana terdapat pengurangan luas areal mangrove dari tahun 2017 hingga 2018 sebesar 36,72 ha, akan tetapi pada tahun 2019 luasan areal mangrove mengalami peningkatan yang cukup besar dari tahun 2018 yaitu sebesar 60,82 ha. Pada tahun 2020 luasan areal mangrove kembali mengalami pengurangan yang cukup drastis yaitu sebesar 181,51 ha. Luasan areal yang tercatat masih ditumbuhi mangrove pada tahun 2020 yaitu hanya sebesar 852,39 ha.
