Judul: Identifikasi Cacing Parasitik Pada Insang dan Gambaran Leukosit Ikan Bawal Air Tawar (Colossoma macropomum) di Kabupaten Bogor
Abstrak: Penelitian ini bertujuan untuk mengidentifikasi cacing parasit pada Colossoma macropomum dan melihat hubungan antara infestasi cacing dengan gambaran hematologi Colossoma macropomum. Penelitian ini menggunakan 30 sampel dari Situ Daun, Ciampea, dan Cibitung Tengah. Organ yang diperiksa adalah insang dan usus. Prevalensi cacing parasit menunjukkan bahwa di Situ Daun adalah 100%, Ciampea 70%, dan Cibitung Tengah 50%. Cacing parasit yang diidentifikasi dari insang adalah subclass dari monogenea, family Diplectanidae, Oncocleidus sp, dan Tetraonchus sp. Tingkat eosinofil meningkat karena infeksi cacing parasit.

Judul: Keberadaan Cacing Parasitik dan Bakteri pada Insang serta Saluran Pencernaan Ikan Nila Bogor Enhanced Strain Tilapia (Oreochromis niloticus)
Abstrak: This study aimed to identify the type of a parasitic worms and bacteria in gills and digestive tract of Bogor Enhanced Strain Tilapia Fish (Oreochromis niloticus) by conventional methods. A group of 10 fishes of sample BEST tilapia were used, each gills and digestive tract was collected. The parasitic worms were colored with KOH and clove oil for nematode worm, and Semichon’s Acetocarmine staining for trematode worms. Differentiations and characterizations of variants isolate were based on biochemical reactions and Gram staining technique. Parasitic worms that can be identified from gills were Dactylogyrus sp. and Pseudodactylogyrus sp., while parasitic worm from digestive tract was Anisakis sp. The bacteria result shows that the gills and digestive tract of BEST tilapia were predominantly contaminated with Aeromonas sp. and followed by Staphylococcus epidermidis and Streptococcus sp.

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.
