<![CDATA[Nostoc merupakan jenis blue green alga yang bisa dijadikan sumber protein potensial bagi manusia. Penelitian ini bertujuan untuk mengevaluasi kandungan protein dan klorofil a dari Nostoc yang dikultur di dua media, Modifikasi Bristol dan BG 11 media, dengan perbedaan konsentrasi MgSO4.7H2O. Di antara kedua media kultur, Nostoc yang dikultur pada modifikasi Bristol media memiliki protein dan klorofil a lebih tinggi dari Nostoc yang dikultur dengan BG 11 media. Berat kering Nostoc dengan Bristol (0.02 - 0.34 gram) lebih tinggi dari BG 11 (0.02 – 0.14 gram). Kandungan protein Nostoc pada Modifikasi Bristol media lebih tinggi (283.58 – 79149.77 μg/gram berat kering) sedangkan yang dikultur dengan BG 11 media (19.31 – 2536.95 μg/gram berat kering). Untuk kandungan klorofil a BG 11 media broth (0.003 – 1.67 mg/gram berat kering) lebih tinggi dari pada Modifikasi Bristol media (0.04 – 1.05 mg/gram berat kering). Perbedaan konsentrasi MgSO4.7H2O. pada kedua media kultur berpengaruh pada kandungan protein dan berat kering dari Nostoc, akan tetapi tidak berpengaruh pada kandungan klorofil a. Penambahan 0,075 gram/liter konsentrasi MgSO4.7H2O selama tiga minggu kultur merupakan kondisi optimal untuk mendapatkan kadar protein dan klorofil a yang optimal untuk modifikasi Bristol media sedangkan pada BG 11 media kandungan protein dan klorofil a yang dihasilkan optimal pada 0,000 gram/liter MgSO4.7H2O. selama satu minggu kultur.Kata kunci : Cyanobacteria, Nostoc, Protein, klorofil a]]>

<![CDATA[The shrimp paste products is one of the traditionally processed products by fermentation. Shrimp paste products are familiar in every layer of society in Indonesia, which is commonly used as a flavoring dishes. A study to identify the diversity of shrimp paste products have been carried to know the home industry diversity of shrimp paste products, in Banten province as well asits physical quality. The shrimp paste products diversity was observed in the market directly and also by interview with the producer in Banten Province. The identification of shrimp paste product was conducted with physical test of filth, that was the foreign materials that mixed-up with raw shrimp paste products. The results showed that there were different raw materials used as well as the product forms, processing, physical quality of the product, pricing and marketing distribution of the shrimp paste products. Almost-uniform product of shrimp paste were found between Pandeglang (TP) and Serang (TS) shrimp paste product, while that of Domas (TD) and Binuangeun (TB) were relatively same in its diversity. Domas (TD) and Binuangeun (TB) shrimp paste product were of good quality, made of terasi shrimp, without dyes additive, and fillers. While that of Pandeglang (TP) and Serang (TS) were of low quality due to the use of waste of salted fish, dyes, and filler material.]]>

<![CDATA[Pathogenic bacterial namely Streptococcus sp has widely spreads in Seabass culture, particularly in fingerlings. It might caused decreasing production quality and quantity. To improve this problem, a study have been done to feed the seabass by using the combination of immunostimulan and antibiotics. The parameter observed were the survival rate and growth rate. Juveniles of 2 cm in size with Streptococcus symptoms were reared in 6 units of 2 m3 tanks with stocking density of 5,000 fishes per tank. They were fed with artificial feeds mixed by immune stimulant and antibiotics (5gr/kg and 2gr/kg, respectively). The experiment was done with 3 replicates and one control for 20 days. The results showed that the survival rates were significantly different between A and B (control) with 20.2% (3,030 ind) and 12.5% (1,875 ind), respectively. There were no significant different in the growth rates between A and B with body length 5.90 cm and 5.80 cm, respectively.]]>

<![CDATA[The potential fisheries in Indonesia has been used by the community in various ways and scale. Most of the existing fishing effort is a small-scale business with a variety of problems faced including the increase in cost, aquatic environment degradation, decline in the catch as well as problems related to non-targeted fishes. In order to overcome these problems required an Appropriate Technology so that the small-scale fishing enterprises can continue to evolve. Types of appropriate technology or so called TTG, which can be adopted to improve the efficiency of small-scale fishing enterprises, namely: attractor squid, deep-sea traps, and fish meat bone separator "Suritech ™". The presence of TTG is expected to provide added value both in economic, ecological and sustainability of fishery resources so that sustainable fisheries can be realized and felt by all walks of life]]>

<![CDATA[Kakap Putih (Lates calcarifer Bloch) adalah salah satu ikan ekonomis penting yang benihnya dapat diproduksi Thailand. Data genetik merupakan salah satu aspek penting dalam mengatur pemijahan induk untuk pemuliaan, namun hingga saat ini informasi terkait keragaman genetiknya masih minim. Penelitian ini bertujuan mengkaji keragaman dan perbedaan genetik kakap putih pada tiga populasi hatchery dan dua populasi alam di Thailand dengan menggunakan metode gabungan antara Restriction Fragment Length Polymorphisms dan Polymerase Chain Reaction (PCR-RFLP) pada D-loop control region di DNA mitokondria. Ditemukan tujuh potongan endonuklease dari 268 sampel yang diamati. Populasi alami Chantaburi (CH) memiliki keragaman haplotipe dan nukleotida tertinggi (h = 0.6626, π = 0.0554) dibandingkan populasi lainnya: tiga populasi hatcheri yaitu Rayong (RA), Chonburi (CB) dan Nakhon Si Thammarat (NK) ) (h berkisar antara 0.2709 – 0.3227; π berkisar antara 0.0195 – 0.386) dan populasi alam Nakhon Si Thammarat (PN) (h = 0.172, π = 0.0091). Mismatch distribution analysis mengungkap kejadian bottleneck pada beberapa generasi sebelumnya di populasi alam PN dan seluruh populasi hatcheri. Analysis of Molecular Variance (AMOVA) menunjukkan 88.95% keragaman disebabkan perbedaan dalam populasi dan 11.05 % disebabkan perbedaan antar populasi. Perbedaan genetik yang signifikan terdapat pada perbedaan antar populasi alam (ΦST = 0.239, P<0.001), namun perbedaan antar populasi hatchery tidak signifikan, menunjukkan terjadi pencampuran genetik sekerabat antar satu dengan hatcheri lainnya. Hal ini karena minimnya masukkan indukan baru dari alam. Kedua hal tersebut dapat menurunkan keragaman dan perbedaan genetik pada setiap populasi hatchery dan antar populasi hatchery.

<![CDATA[A strong demand for high quality of fish seeds can not be fulfilled by the production of seed in the area of Serang district. Many people have to fulfill their needs from out side Banten area. Therefore, in order to support in solving the problem, the Office of Marine and Fisheries Servise of Serang District Government through their laboratory of fish breeding (BBI) in Baros Serang, proposing the development of breeding facilities to enlarge the increasing demand of high quality of fish seeds. This program is important to support the developmen in fish culture in Serang district as well as in Banten Province. A feasibility study for the development of the laboratory of fish breeding have been done on December 1 to 30 March 2011 with using qualitative descriptive analysis method, a simple quantitative analysis and measurement of water quality. Location of the BBI Baros was very suitable, However, the land Area of BBI is inadequate to operate in large scale production. Accordingly, in implementing fish farming based on Indonesian National Standard (SNI), Ways of Good Fish Hatchery (CPIB), Fish Ways Good (CBIB) and stem and seed certification requires Laboratory facilities are adequate. The optimal areas for fish breeding laboratory is about 4 hectares, to prepare the large production scale.]]>
