Abstrak: This study was conducted to get the hematology and blood biochemistry profile of Komodo dragons at Ragunan Zoo. A total of 18 adult dragons were used. Blood was drawn as much as 2 mL whole blood for hematology and 3 mL for blood biochemistry in serum. Hematology examinations were done by automatic hemavet® machine except differential leukocytes were done manually and blood biochemistry examinations were done by biosystem® machine. Examinations results of erythrocyte parameters of total erythrocytes, hematocrit, hemoglobin, MCV, MCH, and MCHC in row are (1,24±0,21) × 106/mm3, (38,0±4,6) %, (13,3±1,6) g/dL, (311,4±49,9) fL, (109,4±18,7) pg, and (35,1±1,2) g/dL. Trombocytes count is (3,1±1.6) × 103/mm3 and erythrocyte sedimentation rate is (3,9 ± 1.7) mm/h. Leukocytes parameters indicate the values of total leukocytes, heterophils, lymphocytes, monocytes, eosinophils, and basophils in row are (6,53±9,47) × 103/mm3, (3,478±4,972) × 103/mm3, (2,959±4,694) × 103/mm3, (0,096±0,187) × 103/mm3, (0,00) /mm3, and (0,00) /mm3. Biochemical parameters indicate the values of total protein, albumin, globulin, AST, ALT, urea, and creatinine in row are (10,19±3,39) g/dL, (2,51±0,39) g/dL, (7,68±3,07) g/dL, (49,39±20,71) IU/L, (45,39±27,88) IU/L, (13,53±5,88) mg/dL, and (0,29±0,11) mg/dL. The result of examinations averagely showed values tend to normal. Some individual results demonstrated abnormalities which are suspected as acute infection in 1 dragon, foliculogenesis in 1 dragon, muscle disease in 2 dragons, and liver disease in 5 dragons.

Judul: Perilaku Komodo (Varanus komodoensis) di Taman Margasatwa Ragunan
Abstrak: The komodo (Varanus komodoensis) is the world's largest lizard that prone to extinction since they only scattered in some small islands in eastern Indonesia. One preservation effort of the dragons is by breeding them in captivity places, such as Jakarta Ragunan Zoo. Eventhought in the captivity, it does not mean there are no problems faced by the komodo. The main problems are because of differences in the weather and environmental conditions. Therefore, the aim of the research is to conduct behavioral assessments of the komodo preserved in the Ragunan Zoo as the first step to resolve the problems. We used observational method called scan sampling. Observations were conducted in two periods of time, i.e. during the daylight (06.00 am-06.00 pm) and evening (6.00 pm-06.00 am). Observations of the behavior of the komodo included walking, stay still, sun bathing, rubbing body, yawn, drinking, eating, climbing, secreting saliva, craning of the tongue, and running. During the daylight, some of the behaviors were more dominant, i.e. walking, stay still, sun bathing, climbing, secreting saliva, and craning of the tongue. While during the night stay still was dominant.

Judul: Katalis Eterifikasi Gliserol Berbasis Poli–(asam stirena sulfonat) dari Limbah Styrofoam.
Abstrak: Styrofoam waste can be converted to poly–(sulfonate styrene acid) (PSSA) that can be used as catalyst. The objective of this research is to get PSSA that can catalyze the etherification of glycerol and benzyl alcohol. The styrofoam waste was converted to PSSA by reacting with H2SO4 98% (as sulfonation agent) and P2O5 (as sulfonation catalyst) at 40 °C for 6 hours. Characterizations of PSSA included functional groups, sulfonation levels, water swelling, and thermal stability. The yield of PSSA was 40-55%. The success of sulfonated polystyrene was shown by –SO3H group absorption at 1157.29 cm-1. Etherification of glycerol and benzyl alcohol using PSSA catalyst was conducted at 110 °C for 12 hours. The conversion in producing mono–benzyl ether glycerol was 8.10%, 1,3–dibenzyletherglycerol 2.60%, and dibenzyl ether 9.80%. Therefore, the PSSA can be used as etherification catalyst.
