Abstract

AbstractIndonesian capture fisheries production reached ± 6.4 million tons in 2014. This number was predictedresulted a huge fishery waste, one of them was swim bladder that potentially contain collagen, so it needs tobe developed. This aim of this study was to determine the characteristics of the swim bladder (proportionand chemical content) and collagen characteristics (yield and physicochemical properties) extracted fromthe swim bladder cunang (Muraenesox talabon). Swim bladder waste had proportion 0.57 to 0.67% of wholeyellow-piked conger body weight and 24.74% protein/100 g wet weight (equivalent to 93.39% of protein/100gram dry). The waste had a potency of collagen, which is characterized by the high proportion of theamino acids glycine, proline, hydroxyproline and alain. Acid extraction and hydrothermal process resultedcollagen extracts, identified from a spectrum of amide I, amide II and amide III functional groups. Collagenextracted with acid process contained a higher glycine than hydrothermal one, but instead hydrothermalprocess produced extract with a higher proline, hydroxyproline and alanine composition.

Abstract

Along with the development of tourism and the well-managed Nusa Dua area, local communities have the opportunity to be able to develop several beach tourism attractions, one of which is Segara Samuh Beach. One of the aquatic organisms that are generally affected by environmental changes is macrozoobenthos, especially the phylum Echinoderms. Based on this, it is necessary to conduct research on the composition of the species of Echinoderms and their distribution patterns. For this reason, it is necessary to conduct an inventory study of the types of echinoderms that exist in the waters of Segara Samuh Beach. This research will be conducted in the waters of Segara Samuh Beach (8° 47' 13.80'' South Latitude and 115° 13' 42.57'' East Longitude), North Kuta District, Badung Regency, Bali. The preliminary survey was carried out in April and data collection was carried out for 2 periods (May 2019 and August 2019). Sample inventory along with data processing and analysis was carried out at the Fisheries Laboratory, Faculty of Marine Affairs and Fisheries UNUD (Echinoderms sample). The largest species composition at Station I was sea cucumber (50%) and at Station II was dominated by snaking stars (54%). Stations III and IV have relatively the same or similar species composition (Figure 2). Subphylum Echinoidea is the species composition with the highest percentage, which are 78.79% and 80.95%, respectively. Other echinoderms found at these two stations were Asteroidea and Holothuroidea, 15.15% and 6.06%, respectively (Station III) and 14.29% and 4.76% (Station IV). Overall, the composition of the Echinoderm species consists mostly of the subphylum Echinoidea (47%), Ophiuroidea (47%), Asteroidea (7%), Holothuroidea (6%) and a little Crinoidea (1%).
