"Penelitian tentang kandungan bahan organik, senyawa n-alkana, aromatik, dan total hidrokarbon dalam sedimen di perairan Raha, Sulawesi Tenggara telah dilakukan pada Juni 2001. Hasilnya menunjukkan bahwa sedimen di stasiun 1 dan 4 telah tercemar oleh hidrokarbon minyak bumi. Hal ini tampak dari perbandingan antara F1/F2 (fraksi hidrokarbon jenuh/fraksi hidrokarbon aromatik) > 1. Sedangkan berdasarkan kandungan total hidrokarbonnya, menurut kriteria dari NAS (National Academy of Science) hanya sedimen di stasiun 2 dan 5 yang telah tercemar oleh senyawa hidrokarbon minyak bumi (>100 ppm).

The content of organic material, n-alkana, aromatic compound and hydrocarbon total in the sediment was carried out in the waters of Raha, Southeast of Sulawesi. Investigation on content of organic material, n-alkana, aromatic compound and hydrocarbon total in the sediment was carried out in the waters of Raha, Southeast of Sulawesi in June 2001. The results showed that the sediment at station 1 and 4 were polluted by hydrocarbon compound. This condition is showed by F1/F2 ratio (comparation between saturated hydrocarbon fraction with aromatic hydrocarbons fraction) > 1. According to NAS (National Academy of Science) criteria on total hydrocarbon content, station 2 and 5 only were polluted by hydrocarbons compound (>100 ppm)."

"Pengukuran kandungan total zat padat tersuspensi (TSS) di perairan Raha Pulau Muna, Sulawesi Tenggara telah dilakukan pada bulan Mei 2001. Hasilnya menunjukkan bahwa kandungan total zat padat tersuspensi berkisar antara 74,8-78,9 ppm dengan kandungan rata-rata 76,5 ppm. Kandungan ini masih sesuai dengan nilai ambang batas yang ditetapkan oleh Kementerian Negara Kependudukan dan Lingkungan Hidup (KLH) tahun 1988 kepentingan perikanan dan taman laut konservasi, tetapi kurang sesuai untuk kepentingan pariwisata (selam, dan renang).

Total Suspended Solid Content in Raha Waters, Northeast of Celebes. Measurement on Total Suspended Solid (TSS) in Raha waters were carried out in May 2001. The results showed that the content of total suspended solid varied between 74,8 ? 78,9 ppm with averages content is 76,5 ppm. This content is still suited to the threshold value stated by government decree in 1988 for fishery and sea conservation park, but not suitable for recreation (swimming, diving activity)."

"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 0.13-1.79􀁭g/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."
