Judul: Analyzing Risk Factors of Toxocara cati Infection on Pet Cats Using A Logistic Regression Model
Abstrak: Regression analysis is one of statistical methods used to model the relationship of explanatory variables and a single response variable. Logistic regression is applied on a categorical response variable typically a binary variable. In this research, the response variable was infection of Toxocara cati with 0 as negative infection and 1 as positive infection. The data was obtained from a survey conducted by a postgraduate student majoring in Veterinary Public Health of Bogor Agricultural University in 2014. The best model was developed by means of best subsets method which resulted in four risk factors namely were sex, availability of defecation sand, frequency of going outside, and repetition of giving anthelmintic. The resulted model showed 70.0% correct in prediction but the sensitivity was only 40.2%. It showed that the resulted model not so good in prediction. It was also described by the area under ROC curve that was only 68.1%. Based on this model, it was shown that risk factors of Toxocara cati infection were the availability of defecation sand and repetition of giving anthelmintic. The significance level of these factors was 5%...

Judul: Analysis of the Dynamic Model of Toxoplasmosis in Cat and Human Populations
Abstrak: Toksoplasmosis merupakan penyakit yang identik dengan kucing. Penyakit ini disebabkan oleh parasit Toxoplasma gondii. Pada penelitian ini, ditinjau model matematika penyebaran penyakit toksoplasmosis dengan menggunakan ukuran populasi yang bervariasi. Tujuan penelitian ini adalah merekonstruksi model, menentukan titik tetap dan bilangan reproduksi dasar (R_0 ), menganalisis kestabilan titik tetap dan sensitivitas parameter, serta melakukan simulasi numerik. Analisis kestabilan titik tetap dilakukan dengan menggunakan fungsi Lyapunov. Dari analisis sensitivitas ditunjukkan bahwa laju transmisi kucing dari populasi kucing rentan ke populasi kucing terinfeksi (laju transmisi horizontal) dan peluang kucing rentan lahir dari kucing yang terinfeksi (laju transmisi vertikal) adalah parameter yang sensitif terhadap R_0.Penurunan laju transmisi horizontal menurunkan nilai R_0.Namun, peningkatan laju transmisi vertikal akan menurunkan nilai R_0. Penurunan nilai R_0, berakibat keadaan bebas penyakit akan tercapai lebih cepat. Pengendalian penyebaran penyakit ini dapat dilakukan dengan dua cara yakni mengurangi laju transmisi horizontal, dan meningkatkan laju transmisi vertikal., Toxoplasmosis is a disease that is identical to cats. This disease is caused by the parasite Toxoplasma gondii. In this study, a mathematical model of the spread of toxoplasmosis was reviewed with various population size. The purpose of this study is to reconstruct the model, determine equilibrium point and basic reproduction numbers (R_0), analyze the equilibrium point stability, and parameter sensitivity, and carried out numerical simulations. Analysis the stability of equilibrium point is determined by using the Lyapunov functions. From the sensitivity analysis determines the cat transmission rate from a susceptible cat population to an infected cat population (horizontal transmission rate) and the probability of a susceptible cat born from an infected cat (vertical transmission rate) are found as sensitive parameters on R_0. Decreasing the horizontal transmission will lower the value of R_0. But, the increase value of the vertical transmission rate can reduce the value of R_0. This implies that the disease free condition would occur. Controlling the spread of this disease can be done by two methods i.e., reducing the horizontal transmission rate, but the vertical transmission rate increase.
