Judul: Kajian Komunitas Lamun di Perairan Pesisir Manokwari
Abstrak: Study of seagrass community in coastal water of Manokwari was done in July-October 2007. The location (sampling points) consisted of seagrass beds that were closed to anthropogenic waste and/or suspended particles sources (i.e. Andai, Wosi, and Briosi) and seagrass beds that were relatively far from those sources (i.e. Rendani and Tj. Mangewa). Seagrass samplings were conducted by line transect and plot methods, environmental parameters were measured. There were eight species collected which included in proineer group (C. rotundata, H. pinifolia, H. uninervis, H. ovalis, S. isoetifolium) and climax group (C. serrulata, E. acoroides, T. hemprichii).

Judul: Distribusi Spasial Komunitas Gastropoda dan Asosiasinya dengan Habitat Lamun di Pesisir Manokwari Papua Barat
Abstrak: Ekosistem lamun yang ada di perairan pesisir pada daerah yang dangkal merupakan ekosistem yang kompleks dan memiliki fungsi yang penting bagi berbagai organisme yang berasosiasi. Salah satu organisme yang berasosiasi dan dominan ditemukan dalam ekosistem lamun adalah gastropoda, yang sangat berperan dalam rantai makanan. Saat ini keberadaan habitat lamun dan gastropoda di Perairan Pesisir Manokwari terancam karena degradasi lingkungan dan dimanfaatkan oleh masyarakat setempat. Hal tersebut yang melatarbelakangi penelitian ini, yang dilaksanakan pada empat lokasi yakni Pesisir Rendani, Pesisir Wosi, Pesisir Briosi dan Pesisir Padarni. Adapun tujuan penelitian ini adalah: (1) Mengetahui dan menganalisis pengaruh parameter fisika-kimia perairan dan tekstur substrat terhadap komposisi spesies, frekuensi, persen tutupan dan kerapatan lamun, (2) Mengetahui dan mengkaji pengaruh kompleksitas habitat padang lamun terhadap kepadatan, keanekaragaman dan keseragaman serta distribusi spesies gastopoda.

Abstrak: Anti rabies serum (ARS) called antibody 1 (Ab1) was used as the antigen to immunize laying chickens. Anti-Ab1 chicken immunoglobulins (IgY), the antiidiotype antibodies against rabies (Ab2) was isolated from chicken blood every week for ten weeks. The highest titer of Ab2 was found at the third week after the last immunization. Immunoglobulin Y was separated by means of ammonium sulfate precipitation, then dialyzed using PBS pH 8.0 for 24 hours at 2 – 8 oC and purified using affinity chromatography column for IgY lead the proteins molecules with 185,000; 95,000 and 49,000 dalton in weigth. Purified IgY was used to immunize New Zealand White rabbit and the antibody response (Ab3) was detected using Agar Gel Precipitation Test (AGPT). The Ab3 showed specific reaction with Ab2 as well as rabies virus. Interestingly, Ab2 and rabies virus express partial identity reaction. This lead the insight, that not all parts of Ab2 are internal image of rabies virus. The efficacy of Ab3 was detected using enzyme linked immunosorbent assay (ELISA) and indicated that the level of Ab3 titer is protective according to WHO standard (more than 0.5 IU/ml). The conclusion of this study is the anti-idiotype antibody can induce protective immune response against rabies virus and can be used as an alternative for rabies anti-idiotype vaccine. Key words : anti-idiotype vaccine, antibody, rabies
