Judul: Incidence of Babesiosis and Anaplasmosis on Cattle in Tanah Datar Regency in 2016-2020
Abstrak: Babesiosis dan anaplasmosis merupakan penyakit yang menyerang sel darah merah, disebabkan oleh Babesia sp. dan Anaplasma sp. dan ditularkan oleh caplak. Penyakit tersebut memiliki dampak yang merugikan, baik dari segi kesehatan maupun ekonomi. Penelitian ini bertujuan untuk mengkaji kejadian babesiosis dan anaplasmosis pada sapi potong di Kabupaten Tanah Datar. Data sekunder mengenai parasit darah didapatkan dari Dinas Pertanian Bidang Peternakan dan Kesehatan Hewan Kabupaten Tanah Datar dengan jumlah sebanyak 375 sampel dari tahun 2016-2020. Hasil menunjukkan rata-rata persentase kejadian anaplasmosis 37,53% lebih tinggi dibanding kejadian babesiosis 11,71% (p<0,05). Sementara itu, tidak terdapat perbedaan rata-rata persentase kejadian babesiosis dan anaplasmosis berdasarkan jenis kelamin dan ras hewan (p>0,05). Berdasarkan hasil tersebut, dapat disimpulkan bahwa infeksi parasit darah yang utama pada sapi potong di Kabupaten Tanah Datar ialah infeksi anaplasmosis dan tidak terdapat perbedaan infeksi berdasarkan jenis kelamin dan ras hewan. Kata Kunci: Anaplasmosis, babesiosis, Kabupaten Tanah Datar, kejadian, sapi potong, Babesiosis and anaplasmosis are diseases that infect red blood cells, caused by Babesia sp. and Anaplasma sp., which are transmitted by ticks. The disease have a negative impact in both health and economic perspective. This study aims to examine the incidence of babesiosis and anaplasmosis on cattle in Tanah Datar Regency. Secondary data of blood parasites were obtained from the Department of Agriculture in Animal Husbandry and Animal Health in Tanah Datar Regency with a total of 375 samples during 2016-2020. The result showed that the average percentage of anaplasmosis 37.53% was higher than that of babesiosis 11.71% (p<0.05). However, there were no difference of the average percentage of babesiosis and anaplasmosis among sex and animal breeds (p>0.05). Based on these results, it can be concluded that the main blood parasite infection on cattle in Tanah Datar Regency is anaplasmosis infection and there is no difference in infection based on sex and animal breeds.

Judul: Prevalensi, Derajat Infeksi, dan Faktor Risiko Infeksi Parasit Darah pada Sapi Potong di Kecamatan Cikalong, Tasikmalaya
Abstrak: This research was aimed to determine the prevalence, intensity of infection, and risk factors of blood parasite infection in cattle of Cikalong subdistrict, Tasikmalaya. Blood smears samples collected from 114 cattle in Cikalong subdistrict and processed using Giemsa staining method. Quantitative evaluation of parasitemia (percentage of infected RBCs) was assesed by counting of the number of parasite erythrocytes present per 500 cells at a magnification of 1000×.The potential of risk factor in regard with livestock management were obtained by interviewing the farmer. The result showed that the highest prevalence rate of blood parasite was Theileria sp. (60.53%), followed by Babesia sp. (44.74%) and Anaplasma sp. (30.70%). Based on sex, the mean of blood parasite in bull was higher than cow. Babesia sp. and Theileria sp. infection in cow was significantly than bull (p<0.05), while Anaplasma sp. infection was not significantly (p>0.05). Based on age, the mean of blood parasite in cattle (>12 month) was higher than calf (<12 month). Babesia sp. and Anaplasma sp. infection in cattle was not significantly than calf (p>0.05), while Theileria sp. infection was significantly (p<0.05). Generally, the prevalence rate of blood parasite was influenced by livestock management, feeding, and vector control was not significantly (p>0.05).

Judul: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
