Abstract

The appearance of whale sharks in several waters in Indonesia has now encouraged the development of tourism activities based on whale sharks. One area that has become a tourist destination for whale sharks both locally and abroad is Botubarani Waters, Gorontalo. Some experts reveal that the presence of whale sharks is influenced by environmental factors, such as salinity, temperature and pH. This study was aimed to measure the value of water quality (temperature, salinity and pH) in the Botubarani whale shark tourist area, Gorontalo so as to create a balance between whale shark tourism and the preservation of the tourist attraction itself. This research was conducted in Botubarani waters, from 8 March to 8 April 2020. The data collection of temperature, salinity and pH was carried out for 30 days. The data collection point is the area where whale sharks were found to surface. Data were collected on temperature, salinity and pH, respectively, using alcohol thermometer, seawater hydrometer and pH test paper. The results showed that the temperature values in Botubarani waters ranged from 24-30.3 ºC, salinity ranged from 33-36 ppt and pH 7. The conditions of Botubarani waters (temperature, salinity and pH) were still in the optimal category for both whale sharks and marine tourism

Abstract

This study was aimed to determine the characteristics of freshwater mussel shell collagen originating from Paku river waters extracted with different concentrations of acetic acid and to determine the best concentrations of acetic acid to produce the highest collagen yields. The different concentration of acetic acids to produce collagen was 0.50 M, 0.75 M and 1 M. The parameters of the analysis observed were collagen yield, proximate analysis (moisture, ash, fat, and protein content), pH and heavy metal analysis (Pb and Cd). The use of 0.50 M acetic acid concentration was the best concentration to produce collagen with the characteristics of a yield value of 18.76%, a moisture content value of 6.64%, ash content value of 82.60%, fat content value of 0.28%, protein content value of 6.81%, a pH value of 6.77, The heavy metal content of Pb 0.53 mg/kg and Cd 0.07 mg/kg.

Abstract

This study aims to obtain data on the abundance of gastropods and bivalves, the density, and the diversity in the mangrove ecosystem in Sebubus Village, Paloh District. The data obtained from this study shed a light in the management of aquatic ecosystems as well as the reference in conserving and identifying mollusks with economic value. Observations from 20 stations revealed that the number of gastropod populations was higher than the population of bivalves. Gastropod abundance was mostly found in Padak and bivalves was mostly found in Engkalan A. Thus, it is necessary to provide information regarding the fishing limits around the mangrove forest o the community. It is necessary to establish a an asylum for gastropods and bivalves as well as support for their sustainability

Abstract

This research aimed to determining physical and chemical characteristics of Kappaphycus alvarezii carrageenan from Bontang and and East Kutai. The method carrageenan extraction process was carried out in the water bath equipped by stirrer. Furthermore, the extraction process was conducted with a constant ratio of seaweed weight to distilled water volume (10:100 g/ml) at 75oC for an hour. The extract was precipitated in Potassium hydroxide (KOH) 6%, potassium chloride 0.2% and ethanol which increase the speed of carrageenan formation. They  were dried in an oven at 60oC for 24 hours. The chemical carrageenan test results showed the  water content seaweed from Bontang (12.7%), East Kutai (12.74%), ash content seaweed from Bontang (32.49 %) and East Kutai (33.80%), pH seaweed from Bontang (8.58) and East Kutai (8.52);  the physical characteristic results showed the fiber seaweed from Bontang (7.45 %) and East Kutai (9.78%), the viscocity of carrageenan  seaweed from Bontang (16.38 cPs) and East Kutai (11.19 cPs) and  gel strength of carrageenan seaweed from Bontang (408.00 g/cm2) and East Kutai (411.67 g/cm2). This physical and hemical characteristics of Kappaphycus alvarezii, meet the quality standard regulated by FAO, FCC and EEC

Abstract

Ikan Tembang (Sardinella spp.) termasuk ke dalam ikan pelagis kecil yang bernilai ekonomis dan ekologis tinggi. Hal ini mengakibatkan perubahan tingkat pemanfaatan yang ditunjukan dengan adanya fluktuasi dari aktivitas penangkapan, sehingga perlu dilakukan kajian terkait stok ikan Tembang. Tujuan dari penelitian ini memiliki tujuan untuk mengetahui hubungan antara panjang dengan bobot, pertumbuhan, laju mortalitas dan tingkat eksploitasi serta ukuran matang gonad dan pertama kali tertangkap. Penelitian dilaksanakan pada September – November 2020 dengan selang waktu pengambilan 1 bulan sekali di Pelabuhan Perikanan Tasikagung Rembang. Metode yang digunakan adalah deskriptif analitik dengan data panjang, bobot dan kematangan gonad. Hasil penelitian diperoleh pola pertumbuhan ikan Tembang bersifat isometrik. Hasil analisis persamaan pertumbuhan von Bertalanffy diperoleh nilai K adalah 0,66, dengan nilai L∞ 185,15 mmTL dan t0 -0,15/tahun. Laju mortalitas total (Z) 0,96, mortalitas penangkapan (F) 0,29 dan mortalitas alami (M) 0,67, dengan tingkat eksploitasi rendah (moderate) yaitu 0,31. Nilai LC 162,22 mmTL > LM 159,67 mmTL mengindikasikan ikan Tembang telah layak tangkap. Kondisi ini menunjukan sumberdaya ikan Tembang yang didaratkan di PPP Tasikagung Rembang masih optimum untuk dimanfaatkan.

Abstract

Skipjack has an essential economic value and it is spread in almost Indonesia’s territorial waters. Skipjack resource utilization activities have contributed greatly to the fisheries sector in Indonesia. The need and high market demand for skipjack causes the fishing intensity is increase. The increasing of skipjack fishing intensity by fishermen in pemana village is concerned that it will threaten the preservation and sustainability of the utilization skipjack resources. The Pemana village is the biggest skipjack producer in Sikka regency. The increasing of the skipjack fishing intensity in this area also occurs every year. Therefore, it is need a skipjack fisheries management in order to ensure the sustainability of skipjack fisheries. A management is development such as ecologically, socially and economically sustainable. This study was aimed to find out the status of sustainable skipjack fisheries that investigated from the economic dimension. The analysis which used was Rapfish (Rapid Apparaisal for Fisheries). The result of Multi-Dimensional Scaling (MDS) revealed that sustainability status of the economic dimension of the skipjack fisheries in Sikka regency was 53,108 or it was in a fair sustainable status. The result of sensitivity Analysis/Leverage of Attributes revealed that there were two key factors of the sustainability of skipjack fisheries such as other income and market oriented. The result of Monte Carlo analysis (eror effect/error) revealed that this analysis had a high confidence level and could be used as an instrument in economic dimension evaluation of skipjack fisheries resources.
