%T HUBUNGAN KUALITAS AIR TERHADAP TERJADINYA HARMFUL ALGAL BLOOMS (HABs) DI LINGKUNGAN KARAMBA JARING APUNG (KJA) PANTAI RINGGUNG
%X Kualitas air merupakan faktor penentu keberhasilan proses budidaya perikanan, khususnya budidaya di karamba jaring apung (KJA). Sebaliknya, kondisi kualitas air yang tidak stabil akan memberikan dampak buruk bagi ekosistem perairan. Salah satu dampak negatif yang dapat ditimbulkan adalah terjadinya ledakan fitoplankton berbahaya (HABs) dengan karakteristik berbahaya karna sifat ?toxsic? dan ?anoxius? yang ada pada fitoplankton itu sendiri Tujuan utama penelitian ini adalah untuk menganalisis keterkaitan antara kualitas air terhadap kemunculan fitoplankton berbahaya (HABs) dengan menggunakan Canonical Corelation Analysis (CCA) dan analisis regresi. Kualitas air penelitian meliputi kecerahan, kedalaman, DO, salinitas, pH, NO2, NO3, NH3, PO4 serta fitoplankton berbahaya (HABs) yang diperoleh saat penelitian. Hasil penelitian diperoleh 30 jenis fitoplankton, dengan 14 jenis diantaranya fitoplankton (HABs) spesifik beracun (toxsic). Kelimpahan fitoplankton secara keseluruhan didominasi oleh Choclodinium, Trichodesmium Erythraeum, Nitzschia Lanceolata dan Pseudo Nitzschia, dimana Choclodinium merupakan fitoplankton dengan kelimpahan tertinggi dengan kepadatan 63.739 sel/l. Kualitas air yang meliputi kecerahan, DO, pH, NO2, NO3, dan PO4 menunjukkan hubungan erat terhadap kelimpahan fitoplankton berbahaya (HABs). Kelimpahan masing-masing fitoplankton dominan secara spesifik mempunyai kecenderungan terhadap unsur hara tertentu, meliputi NO2, NO3, NH3 dan PO4. Kelimpahan Cochlodinium dominan ditentukan oleh NH3 dan PO4; T. Erythraeum ditentukan oleh NO2 dan NO3; serta Nitzschia lanceolata dan Pseudo N ditentukan oleh NO3.


Abstract  Bahasa Inggris

The quality of water is a crucial success factor of aquaculture processes, cultivation especially in floating net (KJA). In contrast, the state quality of unstable water will negatively impact aquatic ecosystems. One of a sure effects could be caused was an explosion of harmful phytoplankton (HABs) with hazardous characteristics due to the nature of "toxsic" and "anoxius" which is in phytoplankton itself. The main objective of this study was to analyze the relationship between the abundance of water quality toward harmful phytoplankton (HABs) using Canonical Correlation Analysis (CCA) and regression analysis. The quality of Water was being researche, included brightness, depth, DO, salinity, pH, NO2, NO3, NH3, PO4 and certain phytoplanktons (HABs) were obtained during the study. The results of the study showed that there were 30 types of phytoplankton found by with 14 types grouped in the specific type of toxic phytoplankton (toxsic). The abundance of overall phytoplanktons dominated by Choclodinium, Trichodesmium Erythraeum, Nitzschia lanceolata and Pseudo N, where Choclodinium an abundance of phytoplankton with the highest density of 63.739 cells/l. The quality of Water included brightness, DO, pH, NO2, NO3 and PO4 showed a close relationship to the harmful phytoplankton abundance (HABs). The abundance of each dominant phytoplankton specifically have a tendency towards certain nutrients ,including NO2, NO3, NH3 and PO4. Cochlodinium dominant abundance determined by NH3 and PO4; T. Erythraeum determined by NO2 and NO3; Nitzschia lanceolata and Pseudo N is determined by NO3.
