Judul: Beberapa sifat virus penyakit ingusan (Malignant  catarrhal Fever) serta peran kambing dan domba dalam penularannya
Abstrak: Penelitian ini bertujuan untuk membuktikan bahwa virus isolat adalah agen penyakit ingusan, mempelajari sifatsifat dan struktur virus dengan berbagai pengujian termasuk antigenisitas dan imunogeniaitasnya. Selain itu peran kambing dan domba sebagai reservoar dan pelepas virus juga dipelajari masing-masing dengan melakukan isolasi virus dari leukosit dan dari ingus, air mata dan cairan vagina/preputium hewan-hewan tersebut. Kurun waktu kambing dan domba sebagai reservoar dan pelepas virus dipelajari melalui penularan buatan kedua jenis hewan: Dari kambing dan domba percobaan dipelajari pula masa inkubasi, gejala klinis dan suhu badan dari infeksi virus MCF.

Judul: Virus sinsisiogenik yang diisolasi dari kerbau tersangka menderita maligrant catarrhal fever (penyakit ingusan)
Abstrak: Penelitian ini bertujuan untuk mendapatkan cara meng- solasi agen penyebab penyakit ingusan (malignant catarr- hal fever, MCF) dari kerbau (dan sapi) dan identifikasinya di Kabupaten Daerah Tingkat II Deli Serdang, Propinsi Dae- ran Tingkat I Sumatera Utara. Sejak tahun 1978 telah terjadi suatu penyakit pada kerbau yang menunjukkan gejala klinik menderita MCF di Ka- bupaten Daerah Tingkat II Deli Serdang, Propinsi Daerah Tingkat I Sumatera Utara. Isolasi agen penyebab penyakit dilakukan dengan mena- nam bahan isolasi (sel dereh, putih dari hewan penderita yang hidup; sel simpul limfe dan sel limpa dari hewan pen- derita MCF yang baru mati) pada biakan sel primer selapis dari tiroid fetus sapi (TPS) atau ginjal fetus sapi (GFS) dan biskan sel lestari Madin Derby Bovine Kidney (MDBK). Fenanaman dilakukan dengan cara lapis sel pengumpan (feeder layer) yaitu penanaman bahan isolasi diatas biakan sel se- Lapis dan dengan cara kokultivasi yaitu penanaman bahan solasi bersama-sama dengan sel individual hasil tripsinasi...dst

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
