The coastal waters of Telukawur Beach Jepara Regency is utilized by the surrounding community for various activities. Sediment transport passed on the rivers also community activities causes turbidity from suspended solids. This situation affects biodiversity especially macrozoobentos in these waters. This study aims to determine the total suspended solids and their effect on macrozoobenthos. The study used a pusposive method. It is used to measure total suspended solids as well as biodiversity

The results showed the total suspended solids in Telukawur coastal waters of Jepara Regency ranged between 104.22 mg / l-134.12 mg / l. The total suspended solids has a very strong effect (r = 0.934) on the abundance of macrozoobentos with a relative abundance range of 10.969%-34.004%. Abstrak Perairan Pantai Telukawur Kabupaten Jepara dimanfaatkan oleh masyarakat sekitarnya untuk berbagai kegiatan. Transport sedimen dari sungai serta aktivitas masyarakat menyebabkan kekeruhan yang berasal dari padatan tersuspensi. Keadaan ini mempengaruhi keanekaragaman hayati terutama makrozoobentos di perairan tersebut. Penelitian ini bertujuan untuk mengetahui kandungan total padatan tersuspensi dan pengaruhnya terhadap makrozoobentos. Penelitian menggunakan metode pusposive dengan mengukur total padatan tersuspensi serta analisa biodiversitas meliputi indeks keanekaragaman, indeks keragaman, indeks dominasi serta keragaman relatif. Hasil penelitian menunjukkan bahwa kandungan total padatan tersuspensi di perairan pantai Telukawur Kabupaten Jepara berkisar antara 104,22 mg/l-134,12 mg/l. Kandungan total padatan tersuspensi berpengaruh sangat kuat (r = 0,934) terhadap kelimpahan makrozoobentos dengan kisaran kelimpahan relatif antara 10,969%-34,004%.
