Abstract

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

Abstract

The development of capture fisheries based on the Code of Conduct for Responsible Fisheries (CCRF) use to optimally the potential of capture fisheries. Fishing gears that use in Dumai City are gill net, push net, and drifting longline. The research was conducted to analyze the fishing gear that used by fishermen in Dumai City based on the CCRF document as a continuation in providing policies of fishing gear. The method of data collection is use a questionnaire and statistic of description is used to data analysis. The results showed the drawbacks of the use of gill nets that are found in the quality of fish caught tend to be slightly physically defective (part of the operculum), and can make the to other species die because the net traps and makes fish spun. Sondong can not be recommended as a good fishing gear based on the CCRF, because the mesh size used is small so the selectivity of sondong is low, and the technique of sondong operation can damage the habitat. Drifting longline is a fishing gear that is selective and environmentally friendly, although viewed from the types of fish that caught, longline has the potential to catch the fish that protected by law based on the main catch is stingrays. However, stingrays that caught by fishermen in dumai are not the fish that protected by law. The conclusion of the study is gill net and drifting longline are recommended fishing gear to fishermen in Dumai city, because it is appropriate with the provisions of the CCRF document

Abstract

Tilapia (Oreochromis niloticus) is one of fish that is suitable to be cultivated in floating net cages or in controlled containers, since tilapia is the omnivorous and is easily adjust to the environment. An artificial feeding in an intensive farming is one of the important supporting factor to increase production. Natural feed available could not meet the needs of fish, therefore in order to promote growth, it must be fulfilled by the artificial feed that could qualify nutrition. The research aims to observing the dose addition of flour Kappaphycus alvarezii in commercial feed to enhance the growth and the survival of O. niloticus. The usability of the research is the costs efficiency of feed and provides information on aspects of tilapia fish farming. The result of the research shows that daily specific growth rate performs that control treatment (0.94±0.14%) gives the best growth response compared to the treatment of seaweed flour 20% (0.06±0.04%), then is followed by the treatment of seaweed flour 5% (0.52±0.17). Further research statistic peforms that the control is significantly different to the treatment of seaweed flour 20% (p<0.05). For the best feed convertion ratio is in control (0.31±0.02) and the lowest is in the treatment of seaweed flour 20% (0.45±0.03). Then the best survival is in control treatment (80.00±0.00%), followed by treatment of seaweed flour 5% (76.670±0.00%) and the lowest survival is in treatment of seaweed flour 20% (63.33±0.06%).
