| Abstract: | Dari hasil penelitian didapatkan sebanyak 3 kelas yaitu Insecta, Chaetopoda, dan Gastropoda yang terdiri dari 17 genera makrozoobentos seperti Prgomphus sp, Allpcapnia sp, Belostoma sp, Hyrophillus sp, Macrovelia sp, Ranatra sp, Tubifex sp, Goniobasis sp, Pleurocora sp, Apella sp, Macrobrachium sp, Viviparus sp, Thiara sp, Lydores sp, Paludestrina sp, Pomatiopsis sp, Sphaerium sp. Nilai kepadatan tertinggi didapatkan dari genera Tubifex sp sebesar 30,86 ind/ m2 yang ditemukan pada stasiun IV (pabrik kayu) dan terendah dari genera Allocapnia sp sebesar 2,43 ind/m2 yang ditemukan pada stasiun III (pengerukan pasir). Nilai Keanekaragaman (H’) makrozoobentos tertinggi didapati pada stasiun II (aktivitas masyarakat) sebesar 1,991 dan terendah pada stasiun III.(pengerukan pasir). sebesar 1,188. dari hasil analisis menunjukkan bahwa penetrasi cahaya, DO, kadar organik sustrat berkorelasi searah sedangkan Ph, temperatur, COD, kecepatan arus dan BOD5 berkorelasi berlawanan. |
| Abstract (other language): | The result showed that there were found four classes (Insecta, Crustaceae, Turbelaria, and Gastropode) within 17 genera of Macrozoobenthic. Tubifex sp has the highest density index with 30,86 ind/m2 that was founded in Fourth station, and Allocapnia sp in thrid station has the lowest density index with 2,43 ind/m2. The Index Diversity (H’) of all station with value between 1,188-1,952 and according to the analysis of Pearson Correlatin, Penetration, Dissolved Oxygen and Organic Substrat has the direct correlated to the Diversity of Macrozoobenthic, while pH, Chemical Oxygen demand, Biology Oxygen Demand saturation has the opposite correlated to the Diversity of Macrozoobenthic, thus Light Penetration and Temperature have constant variables. |
