Judul: Pengelolaan Ekosistem Lamun Kawasan Wisata Pantai Sanur Kota Denpasar Provinsi Bali
Abstrak: Sanur is a famous beach with its white sand and a beautiful sunrise. Besides, a vast expanse of seagrass ecosystems which is provode a high diversity of marine life, covered all over the coast area of Sanur. Unfortunately, we find a less information and discussion of this seagrass ecosystem on the area. The purpose of this research is to analyze the existing conditions and the characteristics of chemical physics of Sanur Coast based on the condition of seagrass ecosystems and their associated biota and furthermore is to make a good management strategies to the seagrass in Sanur Coast. The datas are consists of primary and secondary. Primary data consists of water quality, Coastal profile, and the structure of seagrass vegetation. As for the secondary data are socio-economical data, climate, currents, tides and other supporting data in the study area. These data are obtained from Udayana University, National Bureau of Statistics of Bali Province, Bogor Agricultural University, and Fisheries and Maritime Affairs in Denpasar Bali.This research shows that there are 6 (six) species of seagrass existing in Sanur Coastal. They are Enhalus acoroides (15%), Cymodocea rotundata (24%), Cymodocea serrulata (23%), Halophila ovalis (7%), Halophila uninervis (14%), Syringodium isoetifolium (17%).

Judul: Monitoring dampak pengembangan wilayah Sanur terhadap kualitas perairan pantai Sanur: ditinjau dari peruntukan rekreasi
Abstrak: Tujuan penelitian ini adalah untuk memperoleh gambaran umum tentang kualitas perairan pantai Sanur ditinjau dari sifat-sifat fisik, kimia dan biologisnya dalam peranannya sebagai pantai rekreasi. Di samping itu menduga dampak pengembangan wilayah ini terhadap kualitas perairan pantai, dengan memperhatikan perubahan-perubahan nilai parameter penentu yaitu: BOD (Biological Oxygen Demand), DO (Dissolved Oxygen), fosfat, nitrogen dan kandungan Escherichia coli sebagai indikator pencemaran. Pengamatan dilakukan di 5 stasion utama dengan 15 sub stasion yang terletak di sepanjang pantai Sanur. Air contoh -air contoh yang akan dianalisis diambil dari aliran buangan di setiap stasion dan dari sub stasion-sub stasion yang telah ditetapkan secara acak. Air contoh-air contoh ini dianalisis di Laboratorium untuk pengukuran semua jenis parameter yang ditentukan dalam Rancangan Peraturan Pemerintah Republik Indonesia (RPP-RI), bagi air laut peruntukan rekreasi, kecuali parameter suhu, salinitas, daya hantar listrik (DHL) dan kecerahan dilakukan di lapangan. ...

Judul: Antibodi anti-idiotipe sebagai kandidat vaksin rabies, Anti-idiotype andibody as a rabies vaccine candidate
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
