Judul: Longshore Current Yang Ditimbulkan Oleh Transformasi Gelombang Di Eretan Kulon, Indramayu
Abstrak: Pantai Eretan Kulon merupakan daerah padat dengan berbagai infrastruktur, sehingga mengakibatkan berbagai tekanan terhadap kualitas lingkungan kawasan pantai yang menimbulkan dampak rusaknya lingkungan pantai. Proses erosi pantai timbul secara alami akibat kombinasi pengaruh gelombang dan arus menyusur pantai (longshore current), lebih dipercepat lagi dengan campur tangan manusia.Penelitian bertujuan untuk menganalisis kondisi gelombang dan arus perairan pantai Eretan Kulon, Indramayu, sehingga memperoleh bentuk dari pola dan kecepatan arus pantai terutama longshore current seiring perubahan musim, yang digunakan untuk memprediksi perubahan yang mungkin terjadi dengan menggunakan model matematik. Penelitian dapat memberikan informasi dasar mengenai kondisi perairan pantai dan dampaknya terhadap pantai, sehingga dapat dipakai sebagai bahan acuan Pemerintah Daerah. Data diambil pada bulan Februari, Mei dan Agustus 2006 di perairan pantai Eretan Kulon, Indramayu dengan menanam dua buah mooring yang pada sisinya dipasang alat yaitu current meter dan tide and wave. Pada penelitian ini dilakukan juga sounding ADCP (Acoustic Doppler Current Profiler), untuk mengetahui kontur kedalaman (bathimetri). Pengolahan data dengan Microsoft Excel 2003 dan sofware model RCP Wave.

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
