Abstract

Kota Semarang memiliki Ekosistem Mangrove yang terletak di Tapak Tugurejo. Ekosistem ini dikelilingi oleh berbagai industri dan kemungkinan besar membuang limbahnya ke lingkungan. Hal ini dapat berdampak pada keanekaragaman makhluk hidup di dalam perairan. Penelitian ini bertujuan untuk mengetahui keanekaragaman makrozoobentos sebagai indikator kualitas perairan. Metode purposive sampling digunakan untuk menentukan 9 stasiun pengumpulan sampel. Sampel diambil sebanyak 3 kali dengan selang waktu 2 minggu. Data kemudian dianalisis menggunakan Indeks keanekaragaman, indeks kemerataan, dan indeks dominansi. Hasil penelitian menemukan 15 spesies makrozoobentos, yang didominasi oleh Cerithidea cingulata. Nilai Indeks Keanekaragaman pada ekosistem mangrove rendah (0,86). Kualitas perairan di ekosistem mangrove termasuk dalam kriteria mutu air kelas II.Semarang has mangrove ecosystem in the areal of Tapak Tugurejo. The ecosystem is surrounded by various industries and most probably these plants discharge the sewage to the environment. This might impact on the living creatures in the water. The research was aimed to investigate makrozoobenthos diversity as the indicators water quality. The purposive sampling was used to select 9 stations to collect the samples. The samples were taken three times with the interval of two weeks. Data were analyzed for the diversity index, evenness index, and dominance index. Result find that there were 15 species of macrozoobenthos, Cerithidea cingulata is dominated. The diversity index in mangrove ecosistem is low (0,86). The water quality in mangrove ecosystem include in criteria water quality class II.
