Judul: Kajian Kasus Kriptosporidiosis Pada Sapi Potong Di Kecamatan Ujung Jaya, Sumedang, Jawa Barat
Abstrak: Kriptosporidiosis merupakan zoonosisyang disebabkan oleh protozoa spesiesCryptosporidium.Penelitian ini bertujuan untuk mengkaji dan mengidentifikasi tingkat prevalensi infeksi C. parvum pada sapi potong di peternakan rakyat pada wilayah Kecamatan Ujung Jaya, Kabupaten Sumedang, Provinsi Jawa Barat. Penelitian ini memeriksa sampel feses sapi sebanyak 60 sampel dari 35 peternak. Berdasarkan umur ternak, 60 sampel tersebut terdiri atas 10 pedet, 9 sapi anakan, dan 41 sapi dewasa. Dan berdasarkan jenis kelamin, 60 sampel tersebut terdiri atas 46 sapi betina, dan 14 sapi jantan. Sampel diuji dengan metode pengapungan gula sheaterdan diamati di bawah mikroskop. Prevalensi Kriptosporidiosis di Kecamatan Ujung Jaya masih dalam kategori rendah (11.67%). Melalui analisis statistik didapat hasil bahwa umur dan jenis kelamin tidak meningkatkan prevalensi Kriptosporidiosis secara signifikan (P>0.05) baik pada pedet, anakan, atau sapi dewasa. Berdasarkan hasil deskriptif, prevalensi Kriptosporidiosis lebih tinggi pada sapi jantan (14.29%) daripada sapi betina (10.87%), juga pada sapi dewasa (7.32%) lebih rendah dari pada pedet (20%) dan sapi anakan (22.22%)

Judul: Kajian Kasus Kriptosporidiosis pada Sapi Potong di Kecamatan Ujung Jaya, Sumedang, Jawa Barat
Abstrak: Cryptosporidiosis is a zoonoses caused by Cryptosporidiumspecies. This research were aim to study and identification the prevalence of C. parvum in cattle on Ujung Jaya Regency, Sumedang, West Java. This research studied 60 fecal specimens, consisted of 10 calves, 9 heifers, and 41 adult cattles. And based on gender, consisted of 46 cows and 14 bulls. Samples were examined by floating sheater sugar and microscopic examination. The prevalence of Cryptosporidiosis on Ujung Jaya Regency was 11.67%. Based on statictical analysis, age and gender could not increase the prevalence of Cryptosporidiosis significantly (P>0.05). And based on the descriptive analysis the prevalence of Cryptosporidiosis in bulls (14.29%) higher than in cows (10.87%), and for adult cows (7.32%) is lower than neonate calf (20%) and calf (22.22%).

Judul: Kekonsistenan Hamiltonian pada Gerak Gelombang Interfacial
Abstrak: The interfacial wave is an internal wave that occurs at boundary of two layers fluid. It appears because there is difference of mass density between the two layers. The objective of this thesis is to formulate the motion of internal wave with flat base and flat as well as free upper bound surface. The motion equation obtained is a Hamiltonian system. The Hamiltonian in this system is expressed by variable of wave deviation and horizontal component of potential velocity. Under assumption that interfacial wave moves only in one direction, it can be shown that the Hamiltonian depends on the solution of the wave motion equation. The coefficients of the equation depend on the physical characteristics of the two layers of fluid, i.e. thickness and mass density. The numerical results show that Hamiltonian in the system is constant. It is consistent with Hamiltonian characteristic, which does not depend on time.
