Abstrak: Skabies pada kambing ialah penyakit parasitik yang disebabkan oleh Sarcoptes scabiei var caprae, Psoroptes caprae, Chorioptes caprae, dan Demodex caprae. Penyakit skabies menunjukkan gejala kelainan kulit yang dicirikan oleh hiperkeratosis, dermatitis pruritus, dan alopesia. Tujuan penelitian ini adalah menganalisis jenis pemilihan obat yang digunakan dalam pengobatan penyakit skabies pada ternak kambing serta efektivitas obat tersebut. Data pengobatan kasus skabies didapatkan dari rekam medis UPT Puskeswan Wilayah IV Kabupaten Bogor tahun 2019-2020. Data disusun kemudian diolah menggunakan Microsoft Excel 2019, dilanjutkan dengan analisis secara deksriptif. Hasil penelitian menunjukkan jumlah kasus skabies pada kambing di UPT Pusat Kesehatan Hewan tahun 2019-2020 adalah 481. Ivermektin digunakan sebagai terapi kausatif skabies kambing di UPT Puskeswan Wilayah IV Kabupaten Bogor. Vitamin B12 digunakan sebagai terapi suportif. Dosis ivermektin yang diberikan sejumlah 0,2 mg/kg BB dan dosis untuk terapi suportif 0,1 mg/kg. Ivermektin menjadi obat yang efektif pada penyembuhan penyakit skabies pada kambing berdasarkan literatur., Scabies in goats is a parasitic disease caused by Sarcoptes scabiei var caprae, Psoroptes caprae, Chorioptes caprae, and Demodex caprae. Scabies may have symptoms of hyperkeratosis, pruritic dermatitis, and alopecia. The study was conducted to analyze the commonly used therapy of skabies in goat and its effectivity. The data were collected from the medical records on scabies cases in goats in 2019 and 2020 at the Animal Health Center (AHC) Region IV, Bogor Regency. The data were processed with Microsoft Excel 2019, and were then analyzed descriptively. The total number of cases of skabies in goat recorded during 2019 and 2020 at the AHC Region IV, Bogor Regency was 481. It was known that scabies in goats was treated with ivermectin as causative treatment, while vitamin B12 was given as supportive treatment. The dose of ivermectin given was 0.2 mg/kg BW and dose of vitamin B12 administered was 0.1 mg/kg BW. In conclusion, Ivermectin effective use for therapy scabies in goat based on literature.

Judul: An Overview of Scabies Therapy on Local Cattle in Rokan Hulu Regency, Riau Province, Indonesia
Abstrak: Skabies merupakan salah satu penyakit yang berperan penting dalam sektor peternakan sapi lokal di Indonesia. Oleh karena itu, pemilihan pengobatan yang tepat menjadi sangat penting dilakukan guna meminimalisir dampak skabies. Penelitian ini bertujuan untuk menganalisis kejadian skabies pada sapi lokal di Kabupaten Rokan Hulu dan pemilihan jenis obat serta tingkat efektivitas obat terpilih untuk terapi skabies. Data dalam penelitian ini menggunakan rekapan data Dinas Peternakan dan Perkebunan Kabupaten Rokan Hulu tahun 2016-2020. Data yang diperoleh kemudian dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa kejadian skabies tertinggi terjadi tahun 2016 yaitu sebanyak 145 kasus. Penurunan optimal kejadian skabies terjadi tahun 2019-2020 yaitu hanya tersisa 1,3-2% dari semula. Terapi yang diberikan dalam penanganan skabies di Kabupaten Rokan Hulu berupa terapi kausatif dan terapi suportif. Terapi kausatif yang sering digunakan adalah ivermectin 1% dengan dosis 0,2 mg/kg BB sedangkan terapi suportif yang sering digunakan yaitu kombinasi vitamin E, A, dan D3. Dapat disimpulkan bahwa ivermectin 1% menjadi pilihan terapi skabies di berbagai dunia, termasuk di Rokan Hulu, Riau, Indonesia., Scabies is a disease that plays an important role in the local cattle industry in Indonesia. Therefore, selection of the right treatment is very important in order to minimize the impact of scabies. This study aims to understand the incidence of scabies in Rokan Hulu Regency, to analyze the drug selection and the level of effectiveness of the selected drug for scabies therapy. The data on scabies in the year 2016-2020 were collected from the Department of Animal Husbandry and Plantation Rokan Hulu Regency. The data were analyzed descriptively. From the result, it was shown that the highest incidence of scabies was recorded in 2016 with 145 cases. The optimal reduction of scabies cases were observed in 2019 and 2020 where the incidence of scabies was only 1.3-2%. Treatments of scabies in Rokan Hulu Regency were categorized into causative therapy and supportive therapy. The causative therapy that was most often used was ivermectin 1% at a dose of 0.2 mg/kg BW, while the most common supportive therapy was a combination of vitamin E, A, and D3. It was concluded that ivermectin 1% is the best choice treatment for scabies in multiple countries including Rokan Hulu, Riau, Indonesia.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
