Abstract

Echinoidea (Phylum Echinodermata) is an aquatic biota that has economic value both economic and ecologic. Echinoidea has the characteristics of thorns which can be used as one of the characters in identification and classification. One of classify Echinoidea is to use the numerical-phenetic method. This method was groups each species according to the morphological similarities observed and account. This study aims to determine the types of Echinoidea and its important to grouping because it has important economic value in the fisheries sector and in conducting the data collection of Echinoidea biodiversity. This study used 7 species of Echinoidea namely Tripneustes sp., Euchinotrix sp., Euchinometra sp., Diadema sp., Stomopneustes sp., Heterocentrotus sp., and Colobocentrotus sp. This study used descriptive qualitative method. Analysis data used MVSV 3.1 application for similarity matrix (Simple Matching Coefficient and Jacard Coefficient) and dendogram. The results showed thorns as a characteristic in the classification of Echinoidea. Echinoidea classification shows two groups that have the highest value, namely Euchinotrix sp., And Diadema sp with 80% similarity value and Colobocentrotus sp with Echinometra, sp which is 76% (Simple Matching Coefficient). Whereas based on Jacard Coefficient the two groups have the same similarity value of 53%. Keywords: numeric-fenetic, echinoidea, similarity

Abstract

Penelitian ini bertujuan untuk mengisolasi dan menghitung kelimpahan koloni bakteri Vibrio sp. dari air tambak udang dengan 5 lokasi yang berbeda di Kecamatan Simpang Kabupaten Pidie, Aceh. Penelitian ini menggunakan metode eksploratif dan pengambilan sampel menggunakan purposive sampling. Isolasi bakteri menggunakan media selektif TCBSA. Perhitungan kelimpahan koloni Vibrio sp. menggunakan metode Total Plate Count. Hasil penelitian menunjukkan bahwa kelimpahan bakteri Vibrio sp. di Kecamatan Kembang Tanjong untuk kelima kategori lokasi tambak tergolong aman (104 cfu/ml) yaitu 6,2 x 102 – 2,6 x 103 cfu/ml. Berbeda halnya dengan tambak di Simpang Tiga yang masih dapat dikatakan aman hanya tambak K2T2 (2,9 x 103 cfu/ml), K4T2 (2,2 x 104 cfu/ml, K2T1; K5T; K5T2 (2,3 x 104 cfu/ml) karena kelimpahannya 8,34 x 104 cfu/ml, sedangkan bakteri Vibrio lainnya sudah bersifat patogen (105 cfu/ml). Hasil pengukuran kualitas air tambak menunjukkan rata-rata nilai salinitas 10,67-30,33 ppt, suhu 27,9-33,8 oC, pH air 7,65-8,45, DO 5,35-8,42 dan kecerahan 20-55 cm. Tidak adanya hubungan korelasi yang signifikan dari kualitas air tambak terhadap kelimpahan koloni bakteri Vibrio sp.
