Tujuan penelitian ini adalah untuk mengetahui tekstur sedimen, bahan organik, logam berat (Pb dan Cd), dan kelimpahan makrozoobentos yang terdapat pada Sungai Betahwalang.

Metode sampling yang digunakan adalah metode purposive sampling yang dilaksanakan pada lima stasiun yang diukur selama tiga kali waktu sampling.

Tekstur sedimen yang mendominasi yaitu lumpur, bahan organik yang terkandung dalam kategori sedang, logam berat (Pb dan Cd) dengan kisaran di bawah batas maksimum, dan kelimpahan makrozoobentos sebesar 86,95 – 2565,21ind/grab. Dari hasil penelitian diperoleh hubungan tekstur sedimen dengan bahan organik diduga memiliki hubungan positive adalah fraksi lumpur dengan nilai koefisien korelasi sebesar r = 0,24.

Hubungan antara tekstur sedimen dengan kelimpahan makrozoobentos diduga memilki hubungan positive adalah fraksi lumpur dengan nilai korelasi sebesar r = 0.41. Betahwalang river is a water area that receives material and nutrient from many activities of Betahwalang estuary. The activities are home industry, aquaculture, shipping line, and tourism that continuously without a proper management., The activities is expected to affect of sedimen distribution, organic matter content, heavy metal, and the survival of organism in the sediment. The aim of this research is to explore sediment texture, organic material, heavy metal (Pb and Cd), and macrozoobenthic abundance. We use the purposive sampling method for data collecting at five different stations with three times of sampling. Station 1 is located at ship harbour. Station 2 is located in the area of ship track. Station 3 is located in the confluence of rivers. Station 4 is located at the intersection of rivers. And Station 5 is located at river estuary. The average concentrated results of sand, mud, and clay are 8.65-11.53, 74.67-78.62, and 8.17-16.62, respectively. Sediment texture values dominated are silt.
