Abstract

Brown algae can be functioned as the feedstock on the alginate and fucoidan's sequential extraction biorefinery process. This research aims to obtain the condition of the alkaline treatment process, which provides maximum response towards intrinsic viscosity of Sargassum cristaefolium alginate on the integrated alginate and fucoidan extraction biorefinery process. Factorial Experiment Design of 2k is used to understand the effect of temperature, time, and the concentration of Na2CO3 towards the response of alginate's intrinsic viscosity and determine the correct equation model on the first order of experiment. The research indicated that the different parameters of temperature, time, and Na2CO3 extraction process are tangibly influenced the increasing response of the alginate's intrinsic viscosity, which later reduced after reached its maximum point. The highest alginate intrinsic viscosity of 397.32 ml/g happened during the parameters of the temperature of 60oC, time of 120 minutes, and Na2CO3 concentration of 3%. Therefore, the extraction central point design of 60oC temperature, 120 minutes of duration, and 3% concentration of Na2CO3 is considered correct, and the first-order polynomial experiment model is shaped in the quadratic form.

Abstract

Budidaya rumput laut di Kecamatan Bluto, Kabupaten Sumenep, Jawa Timur, mempunyai kontribusi bagi perekonomian masyarakat pesisir, akan tetapi terdapat kegiatan perikanan seperti penangkapan dan pengolahan hasil laut yang berdampak pada degradasi kualitas air yang berpengaruh langsung kepada hasil produksi rumput laut. Tujuan dari penelitian ini adalah untuk mengetahui lokasi baru pengembangan kegiatan budidaya rumput laut secara berkelanjutan yang terbebas dari kegiatan masyarakat dengan melihat faktor ekologis dan daya dukung perairan di Kecamatan Bluto. Metode yang digunakan mengukur kesesuaian ekologis meliputi suhu, kecerahan, kedalaman, kecepatan arus, kondisi dasar perairan, salinitas, DO, nitrat, ortofosfat, pH, BOD, dan COD, serta estimasi hama dan penyakit rumput laut. Selanjutnya data diskoring untuk menentukan kelas kesesuaian dengan pendekatan SIG. Daya dukung perairan di analisis dengan menghitung 60% dari jumlah kawasan yang sesuai. Hasil penelitian menunjukkan bahwa perairan Bluto memiliki potensi lahan pengembangan rumput laut berdasarkan kelas S1 (sangat sesuai) dan S2 (sesuai bersyarat) seluas 770,19 ha, dan mampu menampung maksimal 42.788 unit rakit rumput laut. Hama dan penyakit yang teridentifikasi di perairan Bluto adalah ikan baronang (Siganus. sp), ice-ice, lumut (Chaetomorpha crassa), dan teritip (Chthamalus stellatus).

Abstract

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 shark, 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

Abstract

This research was conducted at the Central Pakandengan District of Bluto Sumenep, with the aim of: (1) determine the marketing channels and marketing functions, (2) calculate the amount of marketing and profit margins, (3) calculate the percentage level of marketing efficiency at each institution seaweed marketing. Sampling method on farmers is done by using simple random sampling number of 30 respondents and sample marketing agencies using snowball sampling, whereas the method of analysis using the marketing margin analysis, marketing distribution, farmer's share and marketing efficiency. The results show that the first discussion, the marketing channel in the Middle Pekandengan village there are two channels, namely farmer - traders - wholesalers - enterprises and farmers - traders - companies. Marketing functions performed by each agencymarketing is exchange function which consists of sales and purchases, as well as physical function consists of drying, storage, packaging and transport. Second, marketing and profit margins every marketing agencies in each marketing channel is the first marketing channels total marketing margin is Rp. 10,500/kg and the total profit was Rp. 10,250/kg, while the marketing channel II total marketing margin is Rp. 6,000/kg and the total profit was Rp. 5,850/kg. Third, based on the percentage level of efficiency is <50% means it efficiently. I value marketing channel efficiency by 2.08% while the value of the second marketing channel efficiency of 0.83% .

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

Iincreased capture fisheries production at UPT. P3 Pasongsongan is supported by an increase in the number of visiting ships. This in crease in productionmust bebalanced whit proper management. The porpose of this study was to determine the condition of the facilities at UPT. P3 Pasongsongan, knows the management of activities and facilities at UPT. P3 Pasongsongan, and analyzes the right strategy to be applied in the management of P3 Pasongsongan, so that it can provide useful outputs for all aspects related to P3 Pasongsongan. The method used in this research is descriptive method with SWOT analysis to identify various factors in order to formulate a good and appropriate management strategy.based on the results of the analysis that the existing facilities at UPT. P3 pairs are in good condition and still suitable for use, likewise the activities starting from fish marketing, fish processing, and fish marketing are going well, the only constraints are that TPI is not good and ther is no coold storage that can hinder activities in UPT. P3 Psongsongan. While the SWOT anlysis obtained is the result of imlementing the S-O strategy (Streght-Opportunity) which in its applications uses strength to take advantage of opportunities.
