“…This indicates that in general Wangiwangi and Wakatobi is considered suitable for marine tourism. This condition is also supported by the condition of coral reef which is categorized as moderate to good condition with coverage percentage between 28-60% (Yulius et al, 2015).…”

“…The coral reefs of Wangi-wangi are mostly moderately to well-preserved (Yulius et al, 2015) and are not older than ~100 years (Crabbe, et al, 2004). Coral reefs near Kaledupa is dominated by Acropora (Crabbe and Smith, 2002) and the coastline is characterized by mangrove (Setiadi et al, 2010).…”

Wakatobi is one of coastal and marine tourism destination in South–East Celebes Indonesia. Coastal and marine characteristics of this area is composed of diverse biota as the main tourism attraction. Unfortunately, increasing human needs and activities, particularly coral reefs exploitation for construction and other life aspect, endanger the sustainability of marine environment of Wakatobi and the surrounding area. The purpose of this study is to determine marine geology environmental zonation in Wangi–wangi– Kapota Islands, as a consideration for local government in monitoring and regulating the coastal area. The methods that were applied in this study are coastal characteristic mapping, sedimentology, and mineralogy analyses from 34 marine surface sediments. Marine surface sediments have been collected by Marine Geological Institute (MGI) team in 2014. The result indicates that coastal and marine characteristic of Wangi–wangi and Kapota are influenced by geological processes since Middle Miocene. The seafloor morphology is characterized by gentle slopes around coastline that is abruptly changed to very steep slopes seaward. In general, the surficial sediments consisted of biogenic sands that are distributed around coastlines and trapped within coral reefs. Coastal types of this area are generally white coral sand beaches, coral reef platforms, and notches. The area of Wangi–wangi and Kapota can be divided into 4 (four) environmental zone: Flat Plain (Zone I), Sandy Beach (Zone II), Limestone and Coral Reef (Zone III), and Sedimentary Flat (Zone IV). Zone IV in the centre area between Wangi–wangi and Kapota island is considered as the most vulnerable area due to both natural and anthropogenic factor. Keywords: zonation, seafloor morphology, tourism, Wangi–wangi–Wakatobi, Southeast Celebes ProvinceWakatobi adalah salah satu tujuan wisata pantai dan laut yang menarik dikunjungi di Sulawesi Tenggara, Indonesia. Karakteristik pantai dan laut daerah ini disusun oleh keragaman biota laut yang merupakan daya tarik bagi pariwisata. Sayangnya, seiring dengan berkembangnya aktifitas dan kebutuhan manusia, terutama meningkatnya eksploitasi pemanfaatan terumbu karang untuk konstruksi bangunan dan berbagai aspek kehidupan, mengancam kelestarian lingkungan alami Wakatobi dan sekitarnya. Oleh karena itu, penelitian ini dilakukan dengan tujuan untuk membuat zonasi lingkungan pantai dan sekitarnya di Pulau Wangi–wangi dan Kapota, sehingga bisa memberikan pertimbangan bagi pemerintah setempat dalam pengawasan dan regulasi lingkungan kawasan pantai dan sekitarnya. Untuk penelitian ini, metode yang dilakukan adalah pemetaan karakteristik pantai, analisis sedimentologi dan mineralogi yang dilakukan terhadap 34 sedimen permukaan dasar laut. Pengambilan sampel sedimen permukaan dasar laut telah dilakukan oleh Tim Pusat Penelitian dan Pengembangan Geologi Kelautan (P3GL) pada tahun 2014. Hasil penelitian menunjukkan bahwa karakteristik pantai dan laut Wangi–wangi dan Kapota dipengaruhi oleh proses geologi yang telah berlangsung sejak Miosen Tengah. Morfologi dasar laut dicirikan oleh lereng landai di sekitar tepi pantai dan berubah dengan tegas menjadi curam ke arah laut lepas. Pada umumnya tekstur sedimen permukaan dasar laut terdiri atas pasir biogenik tersebar di sekitar garis pantai, dan mengisi di dalam terumbu koral. Jenis pantai sebagian besar berupa pantai pasir koral berwarna putih, pedataran pantai terumbu koral, serta morfologi pantai berupa takik. Kawasan pantai Wangi–wangi dan Kapota bisa dibagi ke dalam 4 (empat) zonasi lingkungan: Flat Plain (Zona I), Sandy Beach (Zona II), Limestone and Coral Reef (Zona III), dan Sedimentary Flat (Zona IV). Zona IV di area tengah antara Pulau Wangi–wangi dan Pulau Kapota merupakan area yang paling rentan mengalami kerusakan lingkungan akibat faktor alami dan aktifitas manusia. Kata kunci: zonasi, morfologi dasar laut, wisata, Wangi–wangi–Wakatobi, Provinsi Sulawesi Tenggara

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%).

“…Hasil pengamatan dan pengukuran persentase luasan tutupan karang hidup di lokasi penelitian diperoleh nilai rata-rata 47,77%. Hal ini sesuai dengan hasil penelitian terdahulu bahwa persentase tutupan karang hidup di perairan Kecamatan Wangi-Wangi antara 22-65% (Hardin 2010), dan 20-60% (Yulius et al 2015).…”
