Judul: Gambaran Darah Macaca Fascicularis Betina Dewasa Sebelum Dan Sesudah Masa Penampungan Di Tempat Eksportir
Abstrak: Berbagai macam perlakuan dan kondisi yang dialami hewan (Macaca Fascicularis) sebelum digunakan, dapt menimbulkan perubahan pada kondisi fisiologinya. Penampungan sementara ditempat eksportir merupakan usaha untuk memperbaiki kondisi hewan melalui pemeriksaan dan perawatan kesehatan serta peningkatan gizi secara intensif sampai hewan dinilai sipa untuk dikirim.

Judul: HEALTH STATUS CHARACTERIZATION OF CONFISCATED Macaca fascicularis AS AN INDICATOR OF REHABILITATION ELIGIBILITY USING ANIMAL WELFARE PRINCIPLES
Abstrak: Eksploitasi satwa liar primata yang cukup besar, dimana spesies Macaca fasicularis atau monyet ekor panjang, merupakan salah satu satwa yang paling banyak diburu dan diperdagangkan di pasar hewan. Kegiatan eksploitasi akibat dari perburuan dan perdagangan satwa liar untuk dijadikan hewan peliharaan dan menjadi hewan pekerja (topeng monyet), serta konflik antara satwa liar dan manusia. Kegiatan eksploitasi tersebut memiliki resiko ancaman terhadap kesehatan masyarakat, resiko penyakit zoonosis dan tidak dipenuhinya prinsip - prinsip kesejahteraan hewan. Pemeriksaan kesehatan merupakan indikator yang dapat diukur dan mewakili evaluasi kesejahteran hewan. Tujuan dari penelitian ini adalah untuk mengkarakterisasi status kesehatan dan mendapatkan standar penilaian kelayakan rehabilitasi individu Macaca fascicularis sitaan selama tahap karantina, dengan menggunakan prinsip kesejahteraan hewan. Tujuan lain dari penelitian ini adalah untuk melihat gambaran status kesejahteraan hewan berdasarkan asal individu. Berdasarkan hasil pemeriksaan kesehatan selama tahap karantina, M. fascicularis memiliki bobot tubuh berkisar antara 0,96 pada kelompok bayi hingga 8,01 pada kelompok dewasa. Sebaliknya, skor kondisi tubuh individu (SKT) berkisar antara 1,50 hingga 4,00. Berdasarkan pemeriksaan fisik dan kondisi gigi, individu dari konflik dan hewan peliharaan dinyatakan sehat secara fisik, dibandingkan dengan kelompok topeng monyet yang memerlukan observasi. Hasil status darah menunjukkan bahwa monyet ekor panjang dari topeng monyet memiliki persentase sehat 85,71%. Berdasarkan pemeriksaan tuberkulosis dengan uji tuberkulin, semua individu dinyatakan negatif. Berdasarkan status prevalensi, 20% individu ditemukan positif endoparasit. Hasil penelitian menunjukkan adanya korelasi antara SKT dengan bobot tubuh dengan koefisien korelasi umum sebesar 0,353. Individu dari kelompok topeng monyet memiliki nilai rata-rata tertinggi dalam hasil penilaian kelayakan rehabilitasi, dengan skor 27,14±1,46, dibandingkan dengan individu asal konflik, yaitu 24,80±1,64, dan hewan peliharaan yaitu 25,11±2,08. Secara umum, semua individu M. fascicularis pada tahap karantina ini dinyatakan layak untuk mengikuti tahap rehabilitasi karena memiliki skor rata-rata 25,53±2,05., The exploitation of primates, where the species of Macaca fascicularis is one of the most hunted and traded animals, in the animal market. Exploitation activities as a result of poaching and trading of wild animals to be used as pets and as working animals (dancing monkey), and as well as human-wildlife conflicts. These exploitation activities have risks of threats to public health, risks of zoonotic diseases, and non-compliance with the principles of animal welfare. Health examination is an indicator that can be measured and represents an evaluation of animal welfare. The purpose of this study was to characterize the health status and obtain a standard for assessing the feasibility of rehabilitation of confiscated Macaca fascicularis individuals during the quarantine stage, using animal welfare principles. Another purpose of the study was to see the overview of animal welfare status based on individuals origin. Based on the results of the health examination during the quarantine stage, M. fascicularis had a body weight ranging from 0.96 in the infant group to 8.01 in the adult group. In contrast, individual body condition score (BCS) ranged from 1.50 to 4.00. Based on physical examination and dental condition, individuals from conflict and pets were declared physically healthy, compared to the dancing monkey group, which required observation. The blood results showed that the longtailed monkey from the dancing monkey had a healthy percentage of

Judul: Which one use to overcome multicollinearity ? Ridge regression or principal component regression
Abstrak: In multiple linear regression the effect of nonorthogonality of the prediction vectors is to pull the least squares estimates of the regression coefficient away from the true coefficient that one is trying to estimate. Separating the effects of each factor of the regressors has been found to be difficult because of high correlation among independent variables. Although the multicollinearity problem has been recognized by many ways, ordinary least squares is still the main technique used in many fields, but the estimation of regression coefficient can present problems when the data vectors for the predictors are not orthogonal, or in this case are multicollinear. In using ordinary least squares, the regression coefficient may be unstable, too large in absolute value, and incorrect with respect to sign. Introduced biased estimation refer to unbiased one that measure the average closeness to the parameter being estimated corresponding to its mean square error (MSE). Ridge regression and principal component can produce better estimates by its own way than those given by ordinary least squares. It may well be preferred estimator since it will have larger probability of being close to true parameter value. Two of the biased regression methods, ridge regression and principal component regression will be applied into this research and discuss briefly for each of its properties. These methods have its particular idiosyncrasy. The biased regression methods attack the collinearity problem by computationally suppressing the effects of the collinearity. Ridge regression does this correctly by modifying the correlation matrix adding a biased constant driving through nonsingular matrix. Principal component regression attacks the problem by regressing Y on the important principal component and then parceling out the effect of the principal component variables to the original variables. Finally translated back the obtained variables into original variables yield the same sign and nearly the same coefficients for both methods.
