Title

Evaluasi epifit dan material yang menempel pada Gracilaria Changii di perairan Maccini Baji, Kabupaten Takalar

Abstract

Gracilaria changii is a series of seaweed that has a high economic value, but in the process of culture, problems are often found that can hinder the cultivation process. One of the things that often hinders the cultivation process of G. changii is due to the presence of epiphytes and adhering materials. Epiphytes are plants that attach to other plants. This study aimed to evaluate the epiphytes and materials attached to G. changiiin Maccini Baji waters, Takalar district. This research was carried out in October-November 2021. The maintenance of seaweed was carried out in the waters of the Maccini Baji hamlet, Takalar district with a maintenance time of 49 days. Sampling was carried out once a week, the parameters observed in this study were identification of epiphytes and adhering material, calculation of weight percentage of epiphytes and adhering material and water quality parameters. The research data were then analyzed descriptively, which were then presented in the form of figures and tables. Quantitative analysis was carried out by weighing the weight after cleaning and before cleaning and then the difference in weight was calculated. The data obtained were analyzed for variance and if there was a difference between locations, it was continued with the smallest significant difference test. The types of epiphytes obtained in this study were Ulva compressa, Cladophora dalmatica, Chaetomorpha crassa, Chaetomorpha linum and Acanthophora spicifera. Other materials attached to the research site include shrimp, shellfish, crabs, baronang and mud, but the most dominant is mud. The highest percentage of epiphytic attachment to G. changii occurred at location 3 in the first week of 43.57% while the smallest percentage of attachment occurred at location 1 in week 6 which was 4.20%. There are three conclusions from this study, namely, the first Epiphytic weight and adhering particles which were found to be dominated by inorganic materials, namely mud. Second, the types of epfits found were Ulva compressa, Cladophora dalmatica, Chaetomorpha crassa, Chaetomorpha linum., Acanthophoraspicifera. Third, the environment that is not in accordance with the needs of seaweed can increase the percentage of attachment of epiphytes and other adhering materials.
