Judul: Studi Seroprevalensi Newcastle Disease pada Unggas Peliharaan Masyarakat di Kecamatan Lore Utara Kabupaten Poso.
Abstrak: This research aims to determine the seroprevalence of Newcastle Disease (ND) on native birds in North Lore Poso District. The research used serum samples from unvaccinated native birds. A total of 45 samples; 22 from domestic chicken and 23 from Muscovy ducks; were taken from Sedoa, Wuasa, and Napu village. Newcastle Disease was determined by Enzyme-linked Immunosorbent Assay (ELISA) method. The seroprevalence of ND in domestic chicken and muscovy ducks were 40.9% and 69.56%, respectively. It was equal with 9 domestic chicken and 13 muscovy ducks that were positive antibody ND. Based on the results, we can conclude that ND virus was present on those three village in North Lore. The area was determined as ND-endemic.

Judul: Studi Seroprevalensi Avian Influenza pada Unggas Peliharaan Masyarakat di Kecamatan Lore Utara Kabupaten Poso Sulawesi Tengah.
Abstrak: Avian Influenza (AI) disease has a huge impact on poultry and human health. These disease caused by influenza virus type A that belongs to family of Orthomyxoviridae. These viruses have two different levels of virulence which is LPAI and HPAI. Wild waterfowls especially Anseriformes (duck, muscovy duck and geese) are the natural reservoir for avian influenza virus and shown subclinical manifestations, which does not display any clinical symptoms. The spreading pattern of AI virus is usually influenced by seasons, where the prevalence of AI was reported to be fall in the rainy seasons. The research aims to determined the seroprevalence of AI in native bird the North Lore, Poso, Central Sulawesi. A total of 22 samples serum of chicken and 23 samples of muscovy duck taken in purposive in Wuasa, Napu and Sedoa village. Samples were tested with Haemagglutination Inhibition Test (HI Test). The results showed that the percentage of positive seroprevalence in the chicken in Napu was 57% and 33% in Sedoa village, with the GMT value of each 20.57 and 20.87, while the serum of muscovy duck from three villages showed a negative result with antigen AI virus or zero seroprevalence.

Judul: Optimasi Konsentrasi Sulfur dan Bahan Pencepat Pada Sintesa Faktis Gelap Dengan Bahan Baku Minyak Jarak Pagar (Jatropha Curcas L.).
Abstrak: Demand increasing on product rubber based have been causing the increasing of factice needs. Dark factice is synthesized by vulcanization of oil and sulfur at high temperatures. In the rubber compound production process, factice function increase homogeneity, save blending time, reduce energy, and produce rubber compounds which more resistant to ozone. The aims of this study were to determine the effect of sulphur and accelerator to physical and chemical character of factice, optimum concentration of both sulphur and accelerator to acetone extract. The experimental design used in this research was Response Surface Method (RSM), consist of two factors, sulphur and accelerator concentration. Low and high value of sulphur concentration low value were 26 pho (part perhundred weight oil) and high value were 30 pho. Accelerator material used are tetramethyl thiuram disulfide (TMTD) and zinc diethyldithiocarbomate (ZDEC). Accelerator concentration factor low value were both 1 pho and high value were 3 pho. Factice production use single feedstock which was jatropha curcas oil. Iodine value and acid value of jatropha curcas oil were each 84.66 g iod/100 g oil and 4.63 mg KOH/g oil. Concentration of 26 pho sulphur and 3 pho ZDEC accelerator resulted the best factice with 20.22 % acetone extract value, 1.03 % free sulphur content, 5.41 % ash content, and pH 11. Factice production with 28 pho sulphur and 3.4 pho TMTD accelerator resulted the lowest acetone extract which its value was 18,60 %, 0.86 % free sulphur content, 4.52 % ash content, and pH 6.37.
