Judul: The Control And Eradication Of Brucellosis In Cattle From The Standpoint Of Human Health
Abstrak: Brucella abortus occurs both in man and cattle. The organism may thrive wherever cattle are raised by man for breeding purposes. As such, spread to humans can easily be lessened if the disease is properly controlled and/or eradicated in cattle. Control of Brucella abortus in cattle can be under taken by continued vaccination, proper attention to hygiene and the particular care taken in the introduction of only brucellosis-free animals into cattle farms. Vac- cination using the strain 19 or strain 45/20 Brucella abortus vaccine is commonly used, though the former is more popular. Each of these vaccine strains has its own advantages and disadvantages. Eradication of Brucella abortus by the test and slaughter policy can also be carried out after proper vaccination programmes have been initiated and a stage reached where only a very small percentage of positive reactors is found,

Judul: Pengembangan kandidat vaksin iradiasi Brucella abortus isolat lapang
Abstrak: Brucellosis is a strategic contagious animal disease in Indonesia, which is caused by Bru/:ella abortus (B. abortus). Brucellosis causes abortion, still birth, orchitis; arthritis, infertility and sterility lowering milk production. Eradication of cattle in many countries have been conducted by test and slaughter and vaccination programme. At the moment there are two vaccinations available to control bovine brucellosis; those are B. abortus S 19 and B. abortus RB51. One of the problems in the eradication is not enough a vaccine. The objective of this research was to develop irradiated brucellosis vaccine from B. abortlls local isolate through isolation, identification and biotyping B. abortus from field cases. Determination of B. abortus radiation dose and in vivo study was done in guinea pigs. The samples were collected from milk (Bandung, west Jawa), amnion fluids (diagnostic sample) and higroma fluids (Be1u, NIT). In this study we use three isolates that were SBDG-13C (milk), CAM-08/306 (amnion fluids), and CH09- BL (higroma fluids). Biotyping of the three isolates categorized as B. abortus biotype I. Standard curves of B. abortus was made by calculating bacteria cells number indirectly. Linear equation of the standard curve of SBDG- J3C; CAM- 08/306 and CH09-BL isolates were y = 7.2119x + 6.7723; y = 3.889lx + 7.5278 and y = 2.9829x + 7.9612 respectively (x is absorbance value and y is log number of cells/ml). Observation on the growth of the isolates after Gamma irradiation showed variation responses to the value LDso of isolate CAM-08/306, CH09-BL and SBDG-I3C were 13.5; 11.9, and 17.9 Gy, respectively. The in vivo study showed that the spleen of irradiation vaccinated guinea pigs was a swelling (splenomegaly) and contained 102 to 106 CFU bacteria. Based on the results, It seems likely that those three isolates have not been defined as candidate isolate for brucellosis vaccine.

Judul: Dimensi Serat dan Komponen Kimia Kayu Reaksi pada Kayu Sungkai (Peronema canescens Jack).
Abstrak: Sungkai (P. canescens Jack) merupakan salah satu jenis pohon andalan untuk pembangunan hutan tanaman industri. Kayunya banyak digunakan sebagai bahan baku pembuatan mebel dan vinir indah. Kajian tentang dimensi serat dan komponen kimia penyusun kayu reaksi kayu sungkai belum pernah dilakukan. Penelitian ini bertujuan untuk menganalisis variasi radial panjang dan tebal dinding serat kayu reaksi, serta variasi radial dan variasi vertikal komponen kimia utama penyusun kayu reaksi. Panjang dan tebal dinding serat diukur melalui sediaan maserasi yang dibuat mengikuti metode Schlutze, sedangkan analisis komponen kimia ditetapkan mengikuti standar TAPPI. Hasil penelitian menunjukkan serat kayu reaksi lebih pendek daripada serat kayu normal dan dinding seratnya lebih tipis. Rata-rata panjang dan tebal dinding serat kayu reaksi 933.86 dan 5.25 μm. Dari pangkal ke ujung batang kadar α-selulosa kayu reaksi cenderung meningkat, sedangkan kadar hemiselulosa berkurang, dan kadar ligninnya relatif konstan. Dibandingkan kayu normal dan opositnya, kadar α-selulosa dan kadar lignin kayu reaksi lebih tinggi, namun kadar hemiselulosanya lebih rendah. Rata-rata kadar α-selulosa, hemiselulosa, dan lignin kayu reaksi berturut-turut 58.19, 1.56, dan 32.43%.
