Pemetaan Perubahan Ekosistem Wilayah Pesisir Kecamatan Dullah Utara Kota Tual

Abstract

The high-use activities, the lack of information and data on the ecosystem as a basic reference for management of coastal areas of the Subdistrict North Dullah. This study aims to determine the potential and distribution of major ecosystems and analyze the rate of change in a certain period of time based on image interpretation. Based on the results of image analysis will be known the extent and distribution of major ecosystems, are then compared with some of the imagery in the past period of time to analyze the rate of change. This research was conducted in the coastal region of North Dullah Subdistrict Tual City. The imagery analysis used the transformation of depth invariant index and supervised classification. Landsat 8 year 2014 image interpretation shows coral reef extents are 1934.82 hectares while for sea grass extents are 614.43 hectares. In 2004 to 2009 there was a increase in coral reef ecosystems extents to 133.56 hectares (4.78%), while for the seagrass ecosystem extents increase to 84.69 ha (14.58%). In 2009 to 2014 coral reefs extent decrease to 992.16 hectares (33.89%) while for seagrass extents decrease to 51.21 hectares (7.69%).

Deteksi Area Kerusakan Pada Citra Terumbu Karang Akibat Coral Bleaching Berbasis Pengolahan Citra Digital

“…Tujuan dari segmentasi citra terumbu karang adalah untuk memisahkan area karang dari latar belakang atau elemen lain dalam citra, sehingga memungkinkan analisis yang lebih mendalam tentang keadaan dan keberagaman terumbu karang. (Thenu & Makailipessy, 2017) dan (Irawan et al, 2017 melakukan penelitian yang bertujuan untuk mengetahui sebaran ekosistem terumbu karang dan luasannya menggunakan citra satelit Landsat dan juga didukung oleh validasi lapangan. Selain menggunakan citra satelit, penggunaan citra yang diakuisisi dengan drone juga bisa dilakukan.…”
