ANALISIS KERAGAMAN BIOTA DAN FAKTOR FISIKO-KIMIA PANTAI KARAPYAK PANGANDARAN UNTUK KEBUTUHAN PENGEMBANGAN KULIAH LAPANGAN TERPADU MAHASISWA CALON GURU BIOLOGI

Abstract

The Karapyak seashore territorial of Pangandaran located in Bagalo Village, Kalicupang District, Ciamis Regency, is a coastal area which has unique specific ecosystem such as a beach with coral extending nearly to the middle of sea. This research employed descriptive methodology. The location of sampling was determined by using Belt Transect and Hand-Sorting method. The organism of sea biota found consisted of four phylla (Arthropod, Coelenterate, Echinoderm and Mollusk). Mollusk was the most phyla of which percentage was at 87.7 %, Echinoderm at 11.8 %, Coelenterate at 4.7 % and Arthropod at 0.5 %. The abundance of the sea biota had a very strong correlation and being in the same direction towards each environment factor measured, whereas the biota variety had the same direction correlation but different in content in which the moderate correlation fit to the temperature at the range of 27 to 31°C, the salinity fit at the range of 3.0-3.1 ‰, the strong correlation fit to pH at the range of 7.16-7.90 and the very strong correlation fit to DO at the range of 0.04 to 0.09 mg/I. This study result implies that there has been an effort to develop a guidance of integrated field study practicum by which integrates among the field practicum subject regarding Zoology of Invertebrate, cryptogam botany and ecology. The discovery of sea biota variety and the existence of variety relationship with the environment factor become the reference source in developing the guidance of integrated field study practicum.
