Abstract

Fucoidan were recovered from Sargassum polycystum by single-step extraction with ultrasonic wave pretreatment. Extraction were optimized using central composite design of respon surface method. Ultrasonic wave pretreatment conditions were 80% amplitude, for 15 minute. Alga solution in 0.03 M HCl ratio 1:20 (b/v) at 70-90oC for 3-5 hour were evaluated during this process to establish a condition to maximize the extraction. The aim this research is getting the optimum conditions extraction yield fucoidan Sargassum sp. Result this reseacrh all extraction factors had significant effects on fucoidan yield (p<0,05). The optimum conditions were extracting temperature 81oC, extracting time 4,04 h. Under this condition, the experimental yield of crude fucoidan 7,15±5,58%. Based on the characterization result of fucoidan by fourier transform-infrared spectroscopy, we foundthat fucoidan Sargassum sp.is composed sulfate group.

Abstract

The purpose of this study was to determine the conditions of the extrusion process which gave a maximum value of intrinsic viscosity response. The 2k factorial design was used to determine the effect of temperature, screw speed and pH on intrinsic viscosity and determine the accuracy of the first-order polynomial model. The temperature treatment, screw speed and pH of alginate extraction extrusion process have a significant influence on intrinsic viscosity. The maximum intrinsic alginate viscosity value of 416.16 ml/g occured under conditions of extrusion process temperature of 60oC, screw speed 75 rpm and pH 10. Quadratic first-order polynomial model, planning of research center temperature 60oC, screw speed of 75 rpm and pH 10 were appropriate.

Abstract

The high demand of shark products, particularly fins, have influenced the increase in the exploitation and trade of sharks, included small scale fisheries. The condition can increase the vulnerability of sharks because of their biological cycle and as a top predator and economically important fish. This paper aims to identify the conditions of exploitation and management of sharks in Sumenep Regency. The method used in this research is the field observation, in-depth interview and review of policies. Based on the existing results indicate that over exploitation has occurred in Sumenep, where fishermen catch almost any size of sharks, both great until the baby sharks ('baby hiu’) in large numbers. Several species of sharks that many caught are the species Carcharhinus melanopterus, C. obscurus, Sphyrna lewini and Chiloscyllium punctatum. Shark trade activities occur in Tempat Pelelangan Ikan (TPI) of Pasongsongan, the fishing port of Ambunten, Dasuk, Dungkek, and Tanjung–Saronggi. Currently, the regulations governing the management and protection of sharks in Indonesia is still limited to only a few species of sharks, including whale sharks (Rhincodon typus), shark saws (Pristis Microdon, P. clavata, P. zijsron, and Anoxypritis cuspidata), and manta rays (Manta birostris and M. Alfredi), although other species has status Near Threatened until Endengered based International Union for Conservation of Nature (IUCN) and Appendix II based on the Convention on International Trade in Endangered species (CITES). Not to socialized existing regulations to the fishermen, the absence of regional policy in particular, and the high price is one reason still rampant shark fishing on a large scale. To that end, public awareness activities to fishermen and communities and appropriate regulation is needed in sustainable shark management efforts.
