Abstrak: Artificial reefs have been submerged in the Karya Island’s reef area which are important for coral recovery. The coral recovery could be identify from coral recruits attached to the surface of artificial reefs. Each coral colony was photographed and identified to the highest taxa based on its coralite. The coral colony’s length and area was measured. Two different substrate materials of artificial reef were observed: nets and PVC. A total of 383 coral colony was recorded attach to the artifial reefs. The highest number of coral recruits was observed on the PVC substrat (347 colonies). Coral recruit on PVC substrate had average length of colonies is 18.5 cm, with montipora as the longest, simmiliar to the nets substrate has highest average of colony its 111,1 ± 124,6 cm2, with Pocillopora as the longest. The PVC substrate was observed as the highest area is 154,5 cm2, with Montipora as the largest area. The study found that suitable substrate for coral recruitment media is PVC with horizontal bottom position.

Abstrak: Coral reefs are a renewable resource that has the important function of Ecology, socio-economic, and culture. In Indonesia, the damage to the coral reef ecosystem is largely due to human activities. To speed up the recovery of coral reefs, several methods of rehabilisationare used such as transplantation and artificial reefs. The purpose of this study was (1) to know the growth rate of coral attached (recruitment) on concrete artificial reef modules, and (2) to determine the structure of coral communities on artificial reefs over a period of 1 year. In this study measured the growth of coral recruitment covering the length and width, survival rates, and recruitment of coral community structure. Types of coral recruitment was dominated by Pocillopora, Millepora and Acropora with a total of 59 species of 65 species of coral recruitment found. Growth in average length was highest in the range of months from January-May 2011 were 0.76±1.98 cm, and the width of the growth of the highest average in the range of months from May-July 2011 were 1.18±0.92 cm.

Abstrak: Lipid oxidation is responsible to the deterioration of meat and meat products. Sausages are popular processed meats which are easy to experience rancid. The addition of naturally occured antioxidant in spices might be possible to reduce the rancidity in meat products. The effect of ethanol clove extract addition at different concentrations (0, 200, 500 and 800 ppm) to inhibit the lipid oxidation of beef and chicken sausages were studied. The treated sausages were stored at chilling temperature of 4oC for 14 days as weel as at freezing temperature of -10oC for 56 days. Antioxidant activity of ethanol extract of clove were measured before its application to sausages. Lipid oxidation (peroxide and TBA value), fatty acid profile, and microbial growth were determined during the storage period. The result showed that ethanol extract of clove had better antioxidant activity than that of BHT (IC50 of ethanol extract of clove was 33 μg/ml, lower than BHT that was 65 μg/ml). All concentrations significantly reduced (p<0.05) the peroxide and TBA values of sausage compared to the control. Sausage with the addition of 800 ppm showed the lowest lipid oxidation and was sensorically acceptable. Combination of ethanol extract of clove and freezing temperature was more effective than combination of etanol extract of clove storing at chilling temperatur.
