Abstrak: Determination of fish fishing ground can be estimated from water condition that is a species habitat. Generally, Oceanography parameters showed water condition. Sea surface temperature and chlorophyl -a are an important oceanography parameters to know the existence and to analyze a potential fishing ground easier. This research was expected could give benefits as sources information for stakeholders who needed such as fisherman to develop the efficiency of catching the fish and to be a recommendation in making policy of skipjack tuna fisheries using. This research was conducted at Mentawai waters (catchment at the field) from March until April 2007. Data of satellite Citra was collected at LAPAN from July-October 2007. The result of this research shows that a result number of skipjack tuna catchment not influenced by sea surface temperature, but it was influenced by concentration of chlorophyl -a. Whereas the lenght of the fish shape was influenced by both of them. Upwelling occurred in August 2006, November 2006 and May 2007 that is at season of east and transition season (between monsoons).

Judul: Perencanaan pengembangan perikanan budidaya air tawar di Kabupaten Bogor Provinsi Jawa Barat
Abstrak: Bogor regency as a buffer zone of Jakarta has long been known as one of the central production of freshwater aquaculture in West Java Province. Beside for self-sufficient, Bogor regency also required to meet the needs of freshwater edible fish for the city of Jakarta. Increasing of development in Bogor regency has affect land use change, such as reducing area for freshwater aquaculture. The objectives of the study were: (1) to identify the existing condition of freshwater aquaculture in Bogor regency, (2) to analyze the role of fisheries and its lingkages with other sectors, (3) to analyze potential area for development of freshwater aquaculture, (4) to explore the perception of stakeholders about the development of freshwater aquaculture, and (5) to analyze the external and internal factors for the development of freshwater aquaculture in Bogor regency, including its strategic plan development. The results have shown that aquaculture production reached 36.007,73 tons with 6.782 farmer and productivity of 5,31 tons/farmer in 2010. Fish consumption rate is 20,95 kg/capita/year with population of 4.763.209. Input-output analysis shown that the fisheries sector has high backward with low foreward power of dispersion. From the stakeholders point of view, the most influential aspect is the economical and the utilization of fishing hatchery aspects. Moreover, further analysis shows that even though the freshwater aquaculture in Bogor regency experiencing many threats, however, at the same time it also has its internal strength. Therefore, the appropriate strategic development of aquaculture in Bogor regency, recommended are: retaining potential fisheries area and preventing land use change; utilizing fish species which are tolerant to water quality; increasing the use of technology and new discovery in cheap protein feed manufacturing; and the utilization of stem and improved seeds.

Judul: Kimiawi imunoglobulin G serta perbedaabbya antara berbagi species hewan
Abstrak: Antibodi adalah molekul protein yang dihasilkan oleh sel plasma sebagai akibat interaksi antara limfosit B peka antigen dengan antigen khusus. Antibodi ini disebut juga imunoglobulin karena molekulnya berbentuk globulin. Jadi imunoglobulin merupakan molekul protein yang membawa akti- vitas antibodi, yaitu sifat kombinasi spesifik dengan zat yang mendatangkan formasi antigen. Diantara kelas imunoglobulin, Ig G adalah yang paling melimpah dalam serum darah. Ig G ini memainkan peran utama dalam mekanisme pertahanan. Ig G merupakan struktur glikoprotein dengan dasar bentuk bangunan diagram tetrapolipeptida yang mengandung 4 ran tai polipeptida dengan 2 rantai berat (H) yang identik dan 2 rantai ringan L) yang identik. Rantai polipeptida ini di bentuk oleh rangkaian asam amino. Tiap rantai berat (H) me ngandung 446 residu asam amino dengam BM (2 x 50.000) Dal ton dan tiap rantai ringan (L) mengandung residu asam amino 213() atau 214 () dengan BM (2 x 25.000) Dalton. Bagian variabel dari rantai berat (VH) mengandung 118 residu asam amino dan bagian variabel rantai ringan (VL) mengandung 108 () atau 109 () residu, sedangkan residu sisanya dari masing-masing rantai adalah bagian konstan (CH dan CL). Adanya perbedaan-perbedaan dalam hal asam amino pada salah satu daerah variabel dapat menyebabkan perbedaan imun respon. ...
