Abstract
Kampung Baru is an area on Bintan Island which is located in Sebong Lagoi Village, Teluk Sebong District, Bintan Regency, Riau Islands Province. This study aimed at determine the structure of the macrozoobenthos community, the condition of the physico-chemical parameters of the waters and the relationship between macrozoobenthos and water quality. This research was conducted using a survey method. Sampling site points of this study using random sampling method with 30 sampling site points at high and low tide. The parameters measured are physical, chemical and biological parameters of the water. The results showed that there were 18 species of macrozoobenthos consisting of 4 classes of macrozoobenthos and 3 phylum at 30 sampling site points, namely mollusca, annelida, and arthhopoda phylum. Based on the ecological index value, it is known that the macrozoobenthos species in Kampung Baru waters are still classified as low with disproportionate conditions. The values of diversity index (low), uniformity index (high) and dominance index (low). Water quality of Kampung Baru waters at high tide still meet quality standards of Kepmen-LH No. 51 of 2004, but at low tide the values of temperature, DO, and salinity parameters did not meet quality standards. The relationship between macrozoobenthos parameters and water quality using PCA analysis where density parameters have a relationship with two parameters, namely temperature and pH.

Summary
Kata Kunci: makrozoobentos, struktur komunitas, kualitas perairan, indeks ekologi, Desa Kampung Baru, Kabupaten Bintan. Tujuan penelitian untuk mengetahui struktur komunitas makrozoobentos, kondisi parameter fisikakimia perairan serta keterkaitan makrozoobentos dengan kualitas perairan. Penentuan titik penelitian menggunakan metode random sampling dengan 30 titik pada saat pasang dan surut. Parameter yang diukur adalah parameter fisika, kimia dan biologi perairan. Berdasarkan nilai indeks ekologi diketahui spesies makrozoobentos di perairan Kampung Baru masih tergolong rendah dengan kondisi yang belum merata. Kualitas perairan Kampung Baru pada saat pasang masih memenuhi baku mutu Kepmen-LH No 51 Tahun 2004, namun pada saat surut nilai parameter suhu, DO, salinitas tidak memenuhi standar baku mutu. Keterkaitan antara parameter makrozoobentos dan kualitas air menggunakan analisis PCA dimana parameter kepadatan memiliki keterkaitan dengan suhu dan pH
