Judul: Pendekatan Metode CHAID dan Regresi Logistik untuk Menganalisis Faktor Risiko Fasciolosis pada Sapi
Abstrak: The blue print of meat self-sufficiency program in 2014 shows that beef self-sufficiency can be achieved in 2014. The increasing of the productivity of local cattle is one of attempt to achieve meat self-sufficiency. Productivity of local cattle can be decreased because of parasitic helmint infection. Chi-square Automatic Interaction Detection (CHAID) method and logistic regression analysis are the approach that can be used to determine the factors causing the infection of cattle by parasitic helmint. The CHAID result in this research was tree diagram. It showed that the grazing area had the strongest association for the occurence of parasitic helmint infection. The result showed that the sensitifity values was 69.80%, specificity values was 50.30% and the classification accuracy overall was 60.60%. In addition, the overall logistic regression analysis obtained 63.80% for classification accuracy percentage with 69.80% for sensitifity value and 57.20% for the specificity value.

Judul: Case Study of Cestode Infection in Friesian Holstein Dairy Cattle at PT Nusantara Agri Sejati Sukabumi Regency West Java Province
Abstrak: Sapi Friesian Holstein (FH) merupakan ras sapi dengan sumber susu yang potensial untuk dikembangkan di Indonesia, oleh karena itu diperlukan manajemen pemeliharaan yang baik untuk menghindari penyakit yang bersifat non-genetik seperti infeksi cestoda saluran pencernaan yang dapat mengurangi produktivitas sapi perah. Penelitian ini bertujuan untuk mengukur tingkat kejadian infeksi cestoda dan mengidentifikasi faktor risiko yang berpengaruh terhadap kejadian infeksi cestoda di PT Nusantara Agri Sejati (NAS) Kabupaten Sukabumi Provinsi Jawa Barat. Penelitian ini menggunakan 34 ekor sapi bunting dan muda (dara). Sampel yang dikoleksi berupa feses serta pengambilan sampel rumput dan tanah di empat titik sekitar lahan PT NAS yang digunakan untuk sumber pakan. Analisis data menggunakan uji chi- square untuk mengukur keberadaan hubungan antara variabel dan perhitungan odds ratio untuk mengukur kuat hubungan paparan dengan kejadian penyakit. Hasil penelitian ini menunjukkan infeksi Moniezia sp. dari kelas cestoda di PT NAS rendah dengan prevalensi sebesar 20,5% dan jumlah telur kurang dari 50 TTGT. Faktor risiko BCS memiliki hubungan nyata terhadap infeksi cestoda di PT NAS (p-value 0,029). Infeksi cestoda di PT NAS dipengaruhi oleh faktor Body Condition Score (BCS). Hal ini berhubungan dengan status gizi BCS 2 lebih rentan terkena infeksi cestoda daripada BCS 3. Perbaikan pakan dan program deworming perlu dilakukan untuk menghindari kenaikan kejadian infeksi cestoda di PT NAS., Friesian Holstein (FH) are a breed of cattle with a potential source of milk to be developed in Indonesia, therefore good management is needed to avoid non-genetic diseases such as digestive tract cestode infections which can reduce the productivity of dairy cows. This study aims to determine and measure the incidence of cestode infection and determine factors that can affect the incidence of cestode infection in PT Nusantara Agri Sejati (NAS) Sukabumi Regency, West Java Province. This study used 34 pregnant and young cows (heifers). Samples were collected in the form of feces as well as grass and soil sampling at four points around the PT NAS land used for feed sources. Data analysis used the chi-square test to measure the relationship between exposure and disease and to calculate the odds ratio to measure the magnitude between variables. The results showed that there are infection with Moniezia sp. of the cestode class at PT NAS is very low with a prevalence (20,5%) and the number of eggs is less than 50 TTGT. BCS risk factors have a significant relationship to cestode infection at PT NAS (p-value 0,029). Cestode infections in PT NAS are influenced by Body Condition Score (BCS) factors. This is related to the nutritional status of BCS 2 which is more susceptible to cestode infection than BCS 3. Improvement in feed management and deworming program need to be carried out due to avoid increases incidence of cestode infections in PT NAS.

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
