Abstract


Mangrove ecosystem is a unique ecosystem in coastal area and has useful economic and ecological function. The aim of this research was to know the characteristic of mangrove water of Tanjung Api-api, South Sumatera based on its environmental paramaters. This research has been done in April-June 2007. Sample of water was collected by using water sampler. Water parameters were measured consist of temperature, salinity, pH, Dissolved Oxygen, Nitrate, Phosphate, Ammonium, Total Suspended Solid and Total Organic Matter. Principal Component Analysis was used to determine characteristic of physico-chemical parameters between observation stations. The results showed that station I (sea area) was characterized by high value for temperature, dissolved oxygen, and pH; station II (mouth river) was characterized by high value of TOM and TSS; while station III (river) was characterized by low value of environmental parameters compared with the other stations.

Keywords : Environmental parameters, Principal Component Analysis, Mangrove, Tanjung Api-api

 

 

Ekosistem mangrove merupakan salah satu bentuk ekosistem pesisir yang unik dan memiliki fungsi ekologis dan ekonomis yang sangat bermanfaat di lingkungan pesisir. Penelitian ini bertujuan untuk mengetahui karakteristik habitat mangrove Tanjung Api-api berdasarkan parameter kualitas perairan. Penelitian ini dilakukan pada bulan april-Juni 2007. Pengambilan sampel air dengan menggunakan water sampler lalu dimasukkan kedalam botol gelap. Parameter air yang diamati meliputi suhu, salinitas, pH, oksigen terlarut, nitrat, fosfat, Ammonia, Total Padatan Tersuspensi dan bahan organik total. Untuk menentukan variasi karakteristik fisika kimia perairan antar stasiun pengamatan digunakan Principal Component Analysis atau PCA. Hasil penelitian menunjukkan bahwa karakteristik perairan mangrove Tanjung Api-api untuk Stasiun I (daerah laut) dicirikan oleh suhu, salinitas, DO dan pH yang tinggi, Stasiun II (mulut muara) lebih dicirikan oleh nilai TOM dan TSS yang tinggi, sedangkan Stasiun III (sungai) dicirikan oleh parameter fisika-kimia air dengan nilai yang lebih rendah dibandingkan dengan stasiun-stasiun yang berada di daerah laut dan muara.
