“…Land-use changes were identified by interpreting verified images which were obtained from Google Earth, such as Landsat/Copernicus images (in 1998 and 2008) and CNES/Airbus images (in 2018). Image interpretation was conducted by using the following parameters, namely, tone and color, texture, shape, size, pattern, location, shadow, and association (Iryadi et al, 2017). Interpretation on images was adjusted to modified land-use classifications proposed by Anderson et al (1976) which consist of industrial, settlement, commercials and services, and non-built-up area.…”

Palembang city has experienced an increase in its population. Population growth results in an increase in activities which enlarge the built-up areas. The increase of built-up areas is one of the indicators of urban growth. The increase in built-up areas is inversely proportional to the vegetation area. Reduced vegetation area might cause an increase in land surface temperature. The aim of the study was to analyze the correlation between urban growth and changes in land surface temperature in Palembang City using descriptive quantitative method and spatial analysis on the data obtained from remote sensing images. The result shows that in 1998-2018, Palembang City has developed to the north (Sukarami District) and to the west (Ilir Barat I District). There has been an increase in the temperature, documented as 2.12°C. There is a correlation between urban growth and changes in land surface temperature in Palembang City

“…Kondisi pH tanah di Bali dan Lombok yang agak masam ternyata tidak menghambat pertumbuhan pranajiwa. Kondisi pH tanah di CAB Bali sesuai dengan hasil temuan (Iryadi et al, 2017). Begitu juga halnya pH tanah di lokasi TNGR Lombok berada sejalan dengan temuan Dharmawibawa et al (2015) yang menyatakan bahwa pH tanah di TNGR pada umumnya adalah agak masam.…”

Pranajiwa (Euchresta horsefieldii (Lesch.) Benn.) merupakan tumbuhan obat tradisional yang persebarannya ada di Bali dan Lombok. Sebagai dasar untuk menentukan kesesuaian pranajiwa terhadap suatu lahan, maka diperlukan informasi ekologi. Survei secara purposive dilakukan untuk mengidentifikasi habitat pranajiwa di Bali dan Lombok pada tahun 2015 dan 2016 dengan mengumpulkan data vegetasi, topografi, iklim dan sifat tanah. Principal Component Analysis (PCA) digunakan untuk menentukan faktor yang berpengaruh terhadap ekologi pranajiwa. Pranajiwa tumbuh di daerah perbukitan dengan suhu >20°C, kelembapan 80% dan pH tanah agak asam. Di Bali, pranajiwa ditemukan pada kemiringan lereng curam dengan ketinggian >1.400 m dpl, sedangkan di Lombok ditemukan pada kemiringan lereng agak curam dengan ketinggian >1.200 m dpl. Populasi pranajiwa hidup secara mengelompok dan keberadaannya di alam dipengaruhi beberapa faktor seperti di Bali yang dipengaruhi oleh suhu, dan kemiringan lereng, kelerengan dan suhu, sedangkan di Lombok lebih dipengaruhi oleh kemiringan lereng dan ketinggian tempat. Informasi ekologi ini dapat mengungkap preferensi pranajiwa dihabitatnya dalam mendukung upaya konservasi.

“…Composite band merupakan penentuan kombinasi tiga kanal warma untuk mendapatkan informasi atau identifikasi citra melalui kemampuan interpretasi operator (Interpreter). Untuk mengenali objek yang terdapat pada tampilan citra seorang interpreter dapat melihat kunci interpretasi yang terdiri dari tekstur, warna, bentuk, ukuran, bayangan, pola, dan asosiasi (Iryadi et al, 2017). Untuk memaksimalkan proses interpretasi diperlukan referensi data lapangan sebagai validasi dari hasil interpretasi.…”

Analisa Distribusi Spasial Vegetasi Mangrove di Desa Pantai Mekar Kecamatan Muara Gembong

Mangrove merupakan vegetasi yang tumbuh di wilayah pesisir dengan kemampuan beradaptasi baik secara morfologi dan fisiologi terhadap lingkungan. Ekosistem mangrove memiliki beragam peran diantaranya peranan ekologi, ekonomi dan sosial budaya. Penyusutan luas hutan mangrove yang terjadi di Kecamatan Muara Gembong menyebabkan penurunan kualitas ekosistem mangrove. Kegiatan rehabilitasi tidak berjalan secara maksimal akibat belum tersedianya peta tematik mangrove untuk menunjang kegiatan penanaman mangrove di wilayah Desa Pantai Mekar yang merupakan salah satu desa di wilayah Kecamatan Muara Gembong. Tujuan penelitian ini menganalisis sebaran mangrove, luas vegetasi mangrove dan persentase kategori tutupan vegetasi mangrove melalui pendekatan penginderaan jauh dan validasi lapangan. Citra yang digunakan pada penelitian ini yaitu citra satelit Sentinel 2A. Metode penginderaan jauh yang digunakan untuk mengetahui sebaran mangrove dengan perpaduan composite band dan supervised classification sedangkan untuk luas vegetasi mangrove dan persentase tutupan vegetasi mangrove menggunakan metode Normalized Difference Vegetation Index (NDVI). Metode validasi lapangan untuk tutupan vegetasi mangrove menggunakan hemispherical photography. Hasil penelitian menunjukan sebaran vegetasi mangrove di Desa Pantai Mekar tersebar di daerah ekowisata, wilayah sekitar sungai, daerah muara sungai, bekas tambak dan sekitar tambak dengan luas hutan mangrove sebesar 377,06 ha. Klasifikasi tutupan vegetasi mangrove terdiri dari 81,53 ha (21,62 %) kategori mangrove padat, 77,11 ha (20,45 %) kategori mangrove sedang dan 218,42 ha (57,93 %) kategori mangrove jarang. Mangrove is a tropical coastal vegetation that has the ability to adapt well morphologically and physiologically in the environment. Mangrove ecosystems have various of functions, including ecological, economical, and socio-culture functions. The extensive depreciation of mangrove forests that occurred in the District of Muara Gembong caused a decrease in the quality of the mangrove ecosystem. The rehabilitation activities have not run optimally, because there have not been any thematic maps to support mangrove planting activities in the Pantai Mekar Village area which is one of the villages in the Muara Gembong Subdistrict area. The purpose of this study is to analyze the distribution of mangroves, mangrove vegetation area and percentage of mangrove vegetation cover categories through remote sensing approach and field validation. The image used in this study is the Sentinel 2A satellite image. Remote sensing method used to determine the distribution of mangroves with a combination of composite band and supervised classification, while for the area of mangrove vegetation and the percentage of mangrove vegetation cover using the Normalized Difference Vegetation Index (NDVI). The field validation method for the mangrove vegetation cover uses hemispherical photography. The results showed that the distribution of the mangrove vegetation in Desa Pantai Mekar spread over the ecotourism areas, watershed, river estuaries, and aquaculture ponds with a total area of 377,06 hectares. The area is consisted of 81,53 hectares (21,62%) dense forest, 77,11 hectares (20,45%) medium dense forest, and 218,42 hectares (57,93%) sparse forest.
