Judul: Karakterisasi Membran Komposit Nilon-Arang Untuk Proses Filtrasi Timbal.
Abstrak: Research about membrane technology that made from nylon thread with extra banana peel kepok charcoal had been done. Membranes had been made from ingredient variation, there are 6.9 g, 6.6 g, 6.5 g, 6.5 g, and 6.5 g nilon thread which added by ingredient of banana peel kepok charcoal in a series are 0.1 g, 0.4 g, 0.5 g, 0.75 g, and 0.25 g. This research had been analyzed about electrical properties, mechanic, and FTIR (Fourier Transform Infra Red) spectrum from membranes that had been made. In addition, the resulting solution filtration tested include density, viscosity, and metal content. Result of this research showed that membrane with ingredient 6.5 g nylon thread added 0.5 g banana peel kepok charcoal is good enough to degradate plumbum in the water. Electrical properties tested by LCR meter showed that the shift curves that prove a change in the electrical properties of the membrane before and after filtration. FTIR tested showed that banana peel charcoal has functional group that are stretching O-H, C=N, C=C, C-N aromatic and C-O. Membrane of nilon thread which added banana peel kepok charcoal has functional group amide and hydrocarbon but both of them are overlap.

Judul: Filtrasi Air Sungai Menggunakan Membran Nilon dengan Metode Dead-End
Abstrak: On this research nylon membrane be used as filtration media of river water. Filtration did use with deadend method it is a methode position of membran is perpendicular with feed. River water characterized physicly before and after filtration. There are characterizations observed viscosity, turbidity, and density. There are three variant mass of nylon 5, 6 and 6.5 grams. The methode of sintesize membrane is phase inversion. Rejection of 6.5 grams is the biggest it is 69.98% for turbidity rejection, 98.67% for viscosity rejection and 21.06% for density rejection. Membrane was test its strength and morphology used Economic Force Sensor and Scanning Electron Microscopy (SEM) before and after filtration in variant mass. The strength of membrane before filtration is more low than membrane after filtration and the more weight nylon mass the more its strength. The size of pore membrane is 5 micrometre and it’s categorized as microfiltration. There is a fouling in morphology of membrane after filtration and the more weight nylon mass the more tiny its pore

Judul: Sarkosporidiosis pada Sapi yang Disebabkan oleh Sarcocystis cruzi
Abstrak: Sarkosporidiosis merupakan penyakit protozoa yang dapat berjalan akut dan kronis. Sarkosporidiosis pada sapi dapat diakibatkan oleh 3 jenis sarkopodea dengan S. cruzi yang bersifta patogen dan paling banyak menyerang hewan sapi. Kejadian sapi yang terserang, mempunyai hubungan dengan umur dan musim. Sapi dari segala umur dapat terserang, tetapi sapi dengan umur di atas 2 tahun lebih banyak terserang. Mengenai musim di Indonesia kejadian sarkopodiosis lebih banyak terjadi pada musim hujan, kejadian di Eropa lebih banyak terjadi pada musim semi dan musim panas.
