Abstract

Macrozoobenthos plays a role in biomonitoring of a body of water, because its life tends to settle in the bottom sediments of waters. The purpose of this study was to determine the diversity of macrozoobenthos as a bioindicator of water quality in the Namu Sira-Sira River, Durian Lingga Village, Langkat Regency, North Sumatra. Sampling was conducted at three stations. Station 1 (Upstream River), Station 2 (Bathing Tourism), and station 3 (Downstream River). This research method uses purposive sampling. Sampling of macrozoobenthos at the bottom of the river using a surber net measuring 30 x 30 cm. The results showed that macrozoobenthos found in Namu Sira-Sira River consisted of 7 orders of 18 families and 23 species. Kenaekargaman index (H') Macrozoobenthos in the Namu Sira-sira River at 3 stations that ranged from 1.42-1.60 (medium diversity category), the level of evenness (E) ranged from 0.72 -0.81 (fairly evenly distributed) and the Dominance index 0.14 - 0.21 (no dominant species). Water quality in the Namu Sira-sira river with a value of 3.97-4.57 (good)

Abstract

Periphyton is one of the biotic components, living attached to various substrates has an important role in providing primary productivity of waters. The purpose of this study was to determine the identification of species, the structure of the periphyton community in natural and artificial substrates, the water quality of the Namu Sira-sira River in Langkat Regency. The data collection method was carried out using the "Purposive Random Sampling" method at three stations according to community activities in the research area.The results of the study obtained species found in natural substrates were 25 species and artificial substrates were 27 species. The community structure including the diversity index (H ') is included in the medium category with a value of 2.48 on natural substrates and artificial substrates with a value of 2.50. The uniformity index value (E) on natural substrates is 0.89 and artificial substrates are 0.90 categorized as high because the distribution of species in each station is even. Periphyton communities on natural substrates have advantages in terms of abundance and diversity compared to artificial substrates due to the complex interactions between environmental factors, substrate quality, and ecological processes that support their growth
