Abstract

Danau Sentani merupakan salah satu danau yang termasuk dalam 15 Danau Prioritas Indonesia. Konferensi Nasional Danau Indonesia I (KNDI I) menghasilkan beberapa kesepakatan yang ditandatangani oleh sembilan menteri terkait. Salah satunya adalah pengembangan sistem informasi, evaluasi dan informasi danau. Perubahan kualitas air dianalisa dengan menggunakan data citra MEdium Resolution Imaging Spectrometer (MERIS). Parameter kualitas air yang digunakan adalah Total Suspended Solid (TSS), Colored Dissolved Organic Matter (CDOM) dan Klorofil-a. Ekstraksi ketiga kualitas air tersebut dilakukan dengan menggunakan 3 (tiga) algoritma koreksi atmosfer MERIS. Ketiga algoritma tersebut adalah Regional Water Processor, Boureal Lakes Processor dan Euthropic Lakes Processor. Perubahan kualitas air ini dipantau pada 10 stasiun yang tersebar di wilayah perairan danau. Selain itu, klasifikasi tutupan lahan di daerah sempadan Danau Sentani digunakan sebagai bahan analisa perubahan kualitas air. Hasil penelitian ini menunjukkan bahwa terjadi perubahan parameter kualitas air dari tahun 2003-2011. Hal ini disebabkan oleh terjadinya perubahan tutupan lahan di daerah sempadan danau. ================================================================================================== Lake Sentani is one of the lakes which is included in Fifteen Indonesian Priority Lakes. The 1st Indonesia Lakes National Conference (KNDI I) resulted agreements which was signed by nine ministries. One of which is developing of information system, evaluation and lakes information. Water-quality changes are analyzed by using MEdium Resolution Imaging Spectrometer (MERIS) image. Parameter of water qualities are Total Suspended Solid (TSS), Colored Dissolved Organic Matter (CDOM) and Chlorophyll-a. Extraction of these qualities use three MERIS atmosphere corrections. Three of them are Regional Water Processor, Boureal Lakes Processor and Euthropic Lakes Processor. Waterquality changes are observed by using 10 station which are spreaded in the water of lake. Beside that, land cover nearby of Lake Sentani is classified in order to be the object of analyzed of water-quality changes.The results shows that there is a change of water-quality from 2003 until 2011. It is caused by the change of its land cover.
