Tujuan penelitian ini adalah mengidentifikasi kompleksitas dasar perairan terumbu karang menggunakan Benthic Terrain Modeler (BTM) pada ArcGIS 10.2 dan pengukuran in situ (rugosity dan keragaan life form) berdasarkan pembagian strata kedalaman di Perairan Pulau Kelapa dan Harapan. Survey lapang dilakukan pada 17-21 Maret 2015 untuk mengumpulkan data dan ground check batimetri, pengamatan terumbu karang, dan pengukuran in situ rugosity di 6, 8 dan 10 meter. Dari lima stasiun pengamatan, kompleksitas dasar perairan tertinggi ditemukan di Timur dan Barat berdasarkan surface to planar area BTM, sedangkan berdasarkan in situ rugosity di Utara dan Selatan. Nilai in situ rugosity berpengaruh terhadap surface to planar area (BTM) untuk kedalaman 8 meter. Life form terumbu yang memengaruhi kompleksitas dasar perairan in situ adalah Dead Coral with Algae (6 meter), Hard Coral (8 meter), dan abiotik (10 meter). Kondisi terumbu karang di Pulau Kelapa-Harapan tergolong sedang dengan life form dominan Coral Massive, sehingga kurang mampu membentuk dasar perairan yang kompleks walalupun hasil BTM mendefinisikan kompleksitas secara detail pada grid 2 meter.

In complex coral cays as Kepulauan Seribu, bathymetric profile may change gradually due to naturally controlled reef accretion/erotion, sand/coral exploitation activities, storms, and mostly several types of fishing techniques (muroami and blast fishing). In this paper, elaboration on bathymetric profiles originated from coupled optic-acoustic dataset will be applied in account for understanding reef fish spawning habitats. A total of 17 reef sites were surveyed in situ to record reef fish with spawning cues (eg: female gravid, male change color, aggregation, etc) in between October 2010-March 2012. A 2008 Quickbird imagery and single beam acoustic data were gridded at 1 m by interpolation using Inverse Distance to Power method resulted in 2-dimension and 3-dimension bathymetric maps thus revealing complex detail of seabed at shallow and deeper depths. Terrain profiles depicting lateral view of bathymetric profile for each reef site were used to describe geomorpological features supporting its role as spawning habitat.

Most applications of remote sensing and GIS in coral reef studies were directed to map reef substratum and coverage of benthic habitats. The objective of this study was to analyze bathymetric dataset in order to classify reef geomorphology structure in Harapan-Kelapa Island, Kepulauan Seribu. Bathymetric data-set applied were, collated from WorldView-2 satellite and single-beam acoustic remote sensing using Mapsounder 585, examined using ArcGIS ® , Benthic Terrain Modeler (BTM) to classify seabed environment into several geomorphology classes. Stepwise calculations of broad and fine Bathymetric Position Index (BPI) were applied into each grid, surficial characteristics of the seabed were analyzed according to several sets of scale-factor, and finally structures of the seabed were classified into 13 geomorphic classes.

Each of them has complicated correlation. As a consequence, we have to watch and manage them well to handle the conservation, especially in the west coast area of Banten Province, an area that is consisted of so many little island. Therefore, the monitoring and protections of this area are difficult, if doing by conventional method, or by direct field perception. The early step to do the coastal zone management is by conduct the sustainable monitoring. One of the methods is by using the interpretation of satellite image, such as the FORMOSAT-2 satellite image. Result from the FORMOSAT-2 satellite image analysis can provide much information which can be developed to determine the management of utilization and protection in t...
