Judul: Kejadian Eaherichia coli Veroto bigenik pada Susu Sapi dari Peternakan di fibupaten Bogor, Sukabumi dan
Abstrak: Verotoxigenic Escherichia coli (VTEC) strains are responsible for serious human illnesses. These stmns are commonly found in milk. The aims of this study were to determine occurrence of E, coli in milk and examine its verotoxigenecity . A total of 351 milk samples, 19 waters and 24 swabs of milk can were collected fiom dab farms in Bogor, Sukabumi and Cianjur. These samples were analyzed for total colifonn by using Most Probable Number (MPN) m e and identification of E. coli and VTEC in the samples by using biochemical, serological and Vero cell cytotoxicity assays. E. coli Of 57:H7 isolates were found in I of 2 14 milk samples collected born d a q farms in Bogor, Sukabumi, 1 of 9 1 milk samples and none in Cianjur. E. coli non 0157:H7 isolates were found in 49 of 214 milk samples collected h m dauy farms in Bogor, Sukabumi, 16 of 91 milk samples and 7 of 46 milk samples in Cianjur. Hemolytic E. coli isolates were found in 2 of 214 milk samples collected b m darry h s in Bogor and 2 of 91 milk samples in Sukablrmi. E. coli non 01 57:H7 isolates were found in 10 of 13 water samples collected from dauy farms in Bogor, Sukabumi 2 of 4 water samples and was not in Cianjur. Milk cans where relatively clean, only one of 17 swabs of milk can collected 6om dairy farms in Bogor positive E. coli non 01 57:H7 and none in Sukabumi and Cianjur. Based on Vero cell cytotoxicity assays, fifty four of the isolates were positive VTEC and 37 isolates were non VTEC. Antibiotic susceptibility tests were determined for 2 isolates VTEC 01 57:H7,ll isolates VTEC non OI 57:H7 and 4 isolates hemolytic E. ccoli. The results showed that one isolate of VTEC 0157:H7 was resistant to tetracycline, chloramphenicol, sdfarnethoxazole; 3 isolates of VTEC non 0157:H7 were resistant to twycline; 6 isolates of VTEC non 0157:H7 were resistant to erythromycin; and all of tested isolates were resistant to bacitracin. The study showed there are an occurrence of VTEC in milk samples from b r y farms in Bogor, Sukabumi and Cianjur.

Judul: Isolasi dan Identifikasi Bakteri Escherichia coli Strain EHEC pada Produk Susu Impor
Abstrak: A research was conducted to isolate and identify Escherichia coli bacteria in imported milk products. Although the products were reheated in a high temperature, milk products were prone to contamination during manufacturing and packaging process. Contamination in milk product can reduce milk quality and enable to endanger the health of consumer. The amount of 114 samples of Import milk products were tested in Laboratory of Bacteriology, Division of Medical Microbiology, Departement of Animal Disease and Veterinary Health, Faculty of Veterinary Medicine, Bogor Agricultural University. A number of 3.51% samples were agglumerated skimed milk powder, butter 9.65%, cream 10.53%, deminal 6.14%, skim milk powder 28.07%, Whey powder 24.56%, youghurt 10.53%, and other skim milk product 7.02%.All samples tested showed negative result or it makes point that there is no pathogenic E. coli.

Judul: Desain dan Konstruksi Perahu Katamaran Fiberglass untuk Wisata Pancing
Abstrak: Bahan baku kayu pembuat perahu/kapal semakin langka dan mahal. Informasi tentang cara pembuatan perahu berbahan dasar fiberglass pun masih sangat sedikit yang dipublikasikan dalam bentuk karya ilmiah. Penelitian yang dilaksanakan pada bulan Maret-Juli 2012 ini memberikan alternatif solusi untuk kedua permasalahan tersebut melalui proses desain dan konstruksi perahu katamaran fiberglass berdasarkan rujukan BKI. Pengolahan data dilakukan dengan metode numeric berupa formula-formula naval architecture untuk mendapatkan nilai parameter hidrostatis dari kapal yang diteliti. Analisis data dilakukan dengan membandingkan nilai rasio dimensi kapal. Pembuatan perahu katamaran fiberglass diawali dengan pembuatan desain perahu, pembuatan model perahu, pembuatan cetakan perahu dan pembuatan perahu. Desain perahu katamaran yang dibuat memiliki dimensi utama sebagai berikut: panjang (LOA), lebar (B), dalam (D) dan jarak antar lambung secara berurutan yaitu : 4 meter; 1,9 meter; 0,55 meter dan 1 meter. Adapun kelengkapan perahu katamaran ini antara lain: kursi, tempat umpan, mesin, palka, tempat alat pancing, tempat accu, lampu, tempat peralatan dan ruang reserve buoyancy. Konstruksi perahu katamaran ini dilengkapi dengan gading-gading dan galar sebagai penunjang kekuatan melintang dan memanjang dari perahu. Cadangan daya apung/reserve buoyancy didesain pada perahu ini untuk memperkecil resiko tenggelam.
