Abstract
Komunitas karang dan ikan karang sering dijadikan sebagai indikator pengaruh aktivitas manusia terhadap lingkungan terumbu karang. Naiknya suhu air laut dapat memengaruhi kehidupan organisme di dalamnya. Salah satu penyebab naiknya suhu air laut adalah masuknya polusi panas. Hal tersebut mendasari pene- liti untuk melakukan penelitian yang bertujuan mempelajari struktur komunitas karang dan ikan karang di Perairan Sebalang, Kecamatan Tarahan, Kabupaten Lampung Selatan, Lampung. Pengambilan sampel dilakukan di 3 stasiun penga- matan. Stasiun penelitian ditentukan menggunakan metode purposive sampling yaitu menentukan stasiun pengamatan dengan mempertimbangkan keberadaan terumbu karang yang berada pada kawasan tempat air laut masuk, kawasan der- maga rakyat, dan kawasan tempat air limbah keluar. Hasil penelitian yang dite- mukan di Perairan Sebalang menunjukkan bahwa kondisi terumbu karang sedang, dengan persentase tutupan karang keras sebesar 24,9%. Tingkat kematian terumbu karang tinggi, terutama pada kedalaman 3 dan 8 meter. Indeks keanekaragaman sedang (0,23-0,70), keseragaman sedang hingga tinggi (0,29-0,70), dan dominansi sedang (0,28-0,65). Kata kunci: Terumbu karang, line intercept transect, tutupan karang hidup, Struktur komunitas Coral communities and coral fish are often used as indicators of the influence of human activities on the coral reef environment. Rising sea water temperatures can affect the life of organisms in it. One of the causes of rising sea water temperatu res is the influx of heat pollution. This is the basis for researchers to conduct res- earch which airned to determine the structure of coral and reef fish communities in Sebalang Waters, Tarahan District, South Lampung Regency, Lampung. Sam- pling was carried out at 3 observation stations. Research stations were determined using a purposive sampling method, namely determining observation stations by considering the presence of coral reefs in areas where sea water enters, people's dock areas, and areas where wastewater exits. The research results found in Seba- lang Waters show that the condition of coral reefs was moderate, with a percen- tage of hard coral cover of 24.9%. Coral reef death rates was high, espe- cially at depths of 3 and 8 meters. The diversity index was moderate (0.23-0.70), moderate to high uniformity (0.29-0.70), and moderate dominance (0.28-0.65). Keyword: Coral reefs, line intercept transects, live coral cover, community structure
