Pemantauan kondisi hidrologi di perairan Raha Pulau Muna, Sulawesi Tenggara telah dilakukan pada bulan Mei dan Juni 2001. Hasilnya menunjukkan suhu berkisar antara 27.80-30.39 oC, salinitas antara 30.0-32.9 ppt, zat padat tersuspensi antara 70-80 ppm, kecerahan antara tampak dasar (td) - 8,5 m, zat hara fosfat antara 0.13-1.79g/l, nitrat antara 0.20-2.66 g/l, oksigen terlarut antara 3,68-4.53 ppm, dan pH antara 7.4 - 8.2. Nilai-nilai tersebut masih baik untuk pertumbuhan dan perkembangan karang, dan masih sesuai dengan kriteria yang ditetapkan oleh Kementerian Kependudukan dan Lingkungan Hidup (KLH) untuk berbagai kepentingan. Variasi kondisi hidrologi bukan merupakan penyebab kerusakan karang di perairan.
Monitoring On Hydrology Condition In Raha Waters Muna Island and Its Relation to Coral Reef Condition. Monitoring on hydrology condition in Raha waters Muna Island, Southeast of Sulawesi were carried out on May and June 2001. The results showed that the temperature vary between 27.80-30.39 oC, salinity between 30.0-32.9 ppt, suspended solid between 70-80 ppm, transparency between see bottom - 8,5 m, nutrient phosphate between 0.13-1.79 g/l, nitrate between 0.20-2.66 g/l, dissolved oxygen between 3,68-4.53 ppm, and pH between 7.4-8.2. The values are still good for coralreef growth and development, and still in good agreement with government criteria for miscellaneous purpose. The variation of hydrology condition is not the caution of coral reef damage in Raha waters. |
