Kualitas Perairan Dan Karakteristik Makrozoobenthos di Perairan Selat Panjang Sekitar Pelabuhan Tanjung Buton Desa Mengkapan Kabupaten Siak Provinsi Riau.
A study aims to understand the water quality and characteristics of macrozoobenthos in the waters around the Tanjung Buton Port has been conducted on December 2010 to January 2011. There were 5 stations and water and macrozoobenthos samplings were conducted twice, 2 weeks interval. Water quality parameters measured were temperature, brightness, turbidity, depth, pH, TSS, salinity and DO, while macrozoobenthos characteristics studied were species, abundance, Diversity index (H‟), Dominancy Index (C) and Uniformity Index (E).
Substrate in the sampling area was mud with sediment fraction ranged from 52.23% - 95.43%. Organic materials present in the substrate ranged from 32.38% - 47.34%. There were 5 classes of macrozoobenthos present, namely Polychaeta (4 species), Gastropod (8 species), Bivalve (6 species), Crustacea (2 species) and Gastrotrich (1 species). The abundance of macrozoobenthos ranged from 134 - 285 organisms/m2, H‟ 1.85 – 3.46, C 0,1 - 0,30 and E 0.88 – 0.96. Water quality parameters are as follow: temperature: 28.2 – 29.7 °C, turbidity: 34.6 - 74 mg/l, TSS:76 - 137.7 NTU, Brightness: 19.8 – 22.8 cm, Depth: 2 – 4.4 m, DO: 5.5 – 6.6 mg/l, Salinity: 24.5 - 33 %o, pH: 8. TSS and turbidity level were more than the standard issued by Indonesian Government (KepMen LH No. 51. 2004). Based on data obtained, it can be concluded that the waters around the Tanjung Buton Port is slightly polluted (except in the St 5); no dominant species, and the macrozoobenthos is well distributed.
Key words: Water Quality, Tanjung Buton Port, Macrozoobenthos, Mengkapan Village
