Judul: Pengetahuan dan sikap masyarakatpemilik anjing di daeah perumahan kampus IPB darmaga, terhadap rabies
Abstrak: Rabies merupakan penyakit zoonosis disebabkan oleh virus, berukuran 75 x 180 nm (1 nm 10-9 meter). Virus rabies dikelompokkan kedalam virus rhabdo, berbentuk peluru, tersusun dari asam inti ribo (RNA), karbohidrat, protein dan lemak. Virus rabies peka terhadap pelarut lemak seperti ether, alkohol, sabun dan deterjen. Meskipun seluruh hewan berdarah panas peka terhadap rabies, namun hewan reservoir dan penyebar utama rabies di Indonesia yaitu anjing, kucing dan kera. Rabies merupakan salah satu penyakit yang ditularkan melalui luka gigitan dan dikenal dengan nama lain penyakit anjing gila. Rabies pada manusia berakibat fatal karena virus menyerang otak dan biasanya akan berakhir dengan kematian penderita. Pada air ludah anjing virus bisa ditemukan 3 7 hari sebelum gejala rabies tampak. Di Indonesia rabies merupakan penyakit zoonosis penting. Hal ini disebabkan meningkatnya kasus rabies dari tahun ke tahun. Usaha pencegahan dan pemberantasan semangkin ditingkatkan, namun daerah tertular maupun daerah tersangka masih cenderung meluas. Penelitian dengan mengambil contoh 29 responden ibu rumah tangga pemilik anjing yang menjadi warga RK-V, Desa Babakan, Kecamatan Ciomas, Kabupaten Bogor. Data di- kumpulkan melalui wawancara mempergunakan daftar pert nyaan kepada ibu rumah tangga tersebut. ...

Judul: Growth, Concentration Chlorophyll-a, and Structure of Macroalgae Gracilaria edulis in the Culture Media Containing Copper
Abstrak: The physiological responses (specific growth rate, concentration of chlorophyll-a, morphological and anatomical structure of the vegetative cells) of the marine macroalga Gracilaria edulis at the different concentrations of copper (0.01 as control, 0.04, 0.06 and 0,5 ppm) delivered continuously for 28 days under controlled laboratory conditions were investigated. Result showed that the degree of copper toxicity depends on both factor the concentration and exposure time. Copper concentration and day of exposure decreased significantly the specific growth rate (SGR) of the Gracilaria edulis but only 0,5 ppm Cu decreased the chlorophyll-a content when compared to control. Of the various physiological end points measured, growth proved to be the most sensitive response than chlorophyll-a with reductions in specific growth rate (SGR). The reason for this could be related to a greater sensitivity of the enzymes involved in growth than those related to chlorophyll-a or a greater energy needs to maintain cellular integrity and metabolic processes under sublethal Cu stress. In all cases, the main effect on vegetative cells were structure changes in cortex and subcortex cells, compared to control, macroalgae exposed to copper showed depigmentation and blending in the lateral branches, heavy staining of the cell wall and severe damage of cell membrane, while the mucilage and the cell walls was densely fibrillar, thick and heavily stained, the cortex cell was clearly vacuolated, the presence of endophytic on the cell wall and endophytic spores in the mucilage. The presence vacuoles should be related to a metal immobilization mechanism, minimizing the Cu toxicity for cells. The epiphytic bacteria can act as a biofilter diminishing the availability of Cu for macroalgae accumulation.
