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: Prevalensi infeksi Cryptosporidium sp pada sapi potong di Kecamatan Cijulang dan Cimerak, Ciamis, Jawa Barat
Abstrak: Cryptosporidium sp is a parasite causes cryptosporidiosis in cattle. Cryptosporidiosis can be transmitted from animals to humans and vice versa (zoonosis). This research aimed to determine the prevalence of Cryptosporidium sp infection in cattle at Cijulang and Cimerak regency, Ciamis, West Java. Fecal specimens from 145 cattles of 77 farmers, consisted of 20 calves, 33 heifers and 92 adult cattles. Based on gender, the sample was consisted of 127 cows and 18 bulls. Sample of feces were examined by floating Sheather sugar and acid-fast staining method. Percentage prevalence of Cryptosporidium sp in Cimerak area (43.18%) was higher than in Cijulang area (14.29%). The result of statistical tests shows the prevalence of Cryptosporidium sp infection based on age and gender is no significant difference (P>0.05). However, based on the results of descriptive, prevalence infection of Cryptosporidium sp in cows (33.1%) was higher than in bulls (23%).

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.
