Full text linkoai:ojs.unhas:article/113This study aimed to determine and compare community structure and assemblages species of zooplankton at Kodingareng and Lanyukang Island. This study used randomly sampling method and the sampling was conducted on July, August and October 2012. Data was analysed using at PRIMER software program. The results showed that zooplankton at Kodingareng and Lanyukang Isla nd had 48 taxa. 47 taxa was found when sampling at dry season and 25 taxa was found when the sampling at wet season. The species was only found at Kodingareng Island were Cypris and Amphipod, while the species was only found at Lanyukang Island was Luciferidae zoea, Tad Pole and Tintinid. The highest average of zooplankton abundance was found at dry season sampling at Lanyukang Island, account for 670 individu/L. The result of ANOSIM showed that the level of significance of zooplankton community structure a t Lanyukang and Kodingareng Island was 0.5%. Based on nMDS plot of zooplankton assemblages species between Lanyukang and Kodingareng Island showed clear seperation. The SIMPER result showed that there was no species seperator of community structure between those islands due to there was the same dominance of species, such as Calanoida, Cyclopoida, dan Chaetognatha
Penggunaan Marka DNA dalam Seleksi Induk Ikan Kerapu Macan (Epinephelus fuscoguttatus) yang Tahan Terhadap Bakteri Vibrio alginolyticus
Full text linkThe objective of the present study was to use selected RAPD markers (Primer UBC-122 and YNZ-22) in parental selection to the bacterial Vibrio alginolyticus resistance in Tiger groupers (Epinephelus fuscoguttatus). Eighteen fish parent samples were challenged with Vibrio alginolyticus and parental selection was examined by a PCR-RAPD method. The results showed that from 18 fish samples, primer YNZ-22 generated 18 fragments while primer UBC-122 generated 8 fragments only (KHP, KB, HB, PB, MKH, MH, K and MK). In addition, the average number of fragments from each samples generated from primer-YNZ was higher (3,2) than from UBC-122 (2,3). This indicates that primer YNZ-22 is better than primer UBC-122 to use in parental selection to the Vibrio alginolyticus resistance in Tiger groupers. From the parental selection, five fish parents (KHP, PB, MH, K and MK) were selected for their high resistance to the bacterial Vibrio alginolyticus

ANALISIS KERENTANAN PANTAI BERDASARKAN COASTAL VULNERABILITY INDEX (CVI) DI PANTAI KOTA MAKASSAR
Full text linkThe vulnerability of Makassar coast was measured using parameters of Coastal Vulnerability Index (CVI). CVIvalue was determined using geomorphology, shoreline change, coastal slope, mean wave height, mean tidalrange, and relative sea level change parameters. The Makassar coast was divided into a numbers of cells, eachwith the length of 1 km and width of 0.5 kminto the sea. CVI values werecalculated for each cell and the coastalvulnerability wereclassifiedinto five categories: very low - low - medium - high - very high. The results show thatthe coastline with high to very high vulnerability index are located at the southern part of Makassar, while thenorthern coastline generally have low to moderate vulnerability. The CVI parameters which contributed to highsusceptibilitywere the coastal slope and the shoreline change parameters.
