Judul: Studi tentang lnfeksi Neospora caninum pada Sapi Perah  Di Indonesia.
Abstrak: Pada dasawarsa antara 1980-1990 pemerintah Indonesia mengimpor sapi perah untuk meningkatkan kualitas dan populasi sapi perah nasional. Dalam kurun waktu tersebut di beberapa negara dunia sedang merebak neosporosis, kemungkinan penyakit tersebut juga memiliki peluang masuk ke Indonesia bersama ternak yang diimpor. Studi ini bertujuan untuk mendapatkan data seruprevalensi neospomsis dan untuk melihat sebarannya pada sapi perah yang ada di Indonesia.

Abstrak: Pada dasawarsa antara 1980-1990 pemerintah Indonesia mengimpor sapi perah untuk meningkatkan kualitas dan populasi sapi perah nasional Dalam kurun waktu tersebut di beberapa negara dunia sedang merebak neosporosis, kemungkinan penyakit tersebut juga memiliki peluang masuk ke Indonesia bersama ternak yang diimpor. Studi ini bertujuan untuk mendapatkan data seroprevalensi neosporosis dan untuk melihat sebarannya pada sapi perah yang ada di Indonesia. Studi dilakukan di sentra peternakan sapi perah Jawa Barat dan Jawa Timur, baik peternakan kecil maupun besar. Data yang digunakan terdiri atas data primer dan sekunder. Studi ini menggunakan 270 sampel serum terdiri atas 193 sampel dari Kabupaten Malang, Jawa Timur, meliputi 17 sampel dari sapi abortus dan 176 sampel dari sapi non abortus, serta 77 sampel dari Kabupaten Sukabumi, Jawa Barat yang meliputi 38 sampel dan sapi abortus dan 39 sampel dari sapi non abortus. Uji statistika lanjutan dilakukan dengan uji selisih dua proporsi yang bertujuan untuk membandingkan proporsi seroprevalensi neosporosis berdasarkan wilayah (Jawa Barat dan Jawa Timur) serta kelompok abortus dan non abortus. Berdasarkan hasil uji serologi dengan teknik ELISA menggunakan Biogal ImmunoComb Neospora caninum kit pada sampel serum dari peternakan di Jawa Barat dan Jawa Timur telah dapat mengindikasikan adanya infeksi Neospora caninum sebagai penyebab abortus pada sapi perah di Indonesia.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
