Abstract

Bacillus sphaericus H-5a5b is an entomoathogenic agent which showing high potency for vector control, highly specific to insect target, and do not produce any adverse environmental impact. Such agent would be promising for vector control in Indonesia. The present studies is aimed to observing the toxicity status of Bacillus sphaericus H-5a5b (VCRC B42) against Culex quiquefascitus larvae. The larvae of Culex quiquefascitus were reared under the laboratory conditions. The powder of VCRC B42 were prepared by Vector Control Research Centre (VCRC), India. Bioassays on VCRC B42 agains larvae of Culex quiquefascitus were also carried out under the laboratory conditions. The value of LD50 and LT50 for VCRC B42 were decided using probit analysis. The toxicity status was compared with standart of VCRC India. The result of the bioassays showed that the VCRC B42 was moderately toxic agains larvae of the Culex quiquefascitus. The value of LD50 for VCRC B42 was 0.058 mg/l and LT50 about 27 hours.

Abstract

An analysis on the chemical compounds of flowers and leaves of Chromolaena Odorata (L.) R.M. King and H. Robinson from Timor island using GCMS, was conducted. Total number of the compound from flowers which can be detected were 18 considered of alkanes, oxygenated hydrocarbon, fatty acid, hydrazine, and alkaloid along with two unidentified compound (1,2). Twenty seven compound detected from leaves were identified as alkanes, fatty acid, alkaloid, hydrazine together with 12 unidentified compound (3-14). Compounds were identified using NIST Library data. Flower and leaves Chromolaena Odorata contained allelopathy compounds such as palmitic aid, linoleic acid, and 2.6-dimetoxy phenol.

Abstract

There are 2 methods for separating the pesticide by extraction. The first (solid method) use 3 organics solvent: acetonitriil, Petrolium ether, and Dichloromethane, and the second (alternative method) use 2 organic solvent, there are Dichloromehane and Petrolium ether. These two methods was compared in order to know which one is usable to detect the pesticide residue in soybean. The concentration of the carbary residu for the first method was 0.0302 ppm. In the second one the residu that found still lower from limit of ADI that patent by WHO : 0.1 pm and the residu carbufuran undetectioned. The result, showed that the second method can't be used as alternative method.

Abstract

One of the pesticide which very common to protect plants from the pest is diazinon. But this pesticide contain neurotoxic organophosphate bound. The organophosphate bound has also an effect on kidney's tissue. Recently the research about effect of diazinon still required. The study was carried out to observe the effect of diazinon on cells of tubuli renalis in mice. This study was used 30 mice, by random sampling became 6 goup. Three groups for controle (K1, K2, and K3) and three groups for treatment (P1, P2, and P3). The controle groups were given 0.5 ml aquadest and the treatment groups were given 150 ppm of 0.5 ml diazinon solution up to 10, 20, and 40 days for P1, P2, and P2 sub sequently. The result showed that the effect of diazinon solution given per oral for the difference time were caused difference demage level on cells ob the tubuli renalis in mice. Keywords : diazinon, cells of tubuli renalis

Abstract

Bawean deer (Axis kuhlii) is endemic to Bawean island with its status under IUCN record as RARE. Information on the calving pattern in nonexistence and there is a need to understand more on their reproduction physiology for conservation purposes. Record on the calving from Bawean Deer and others tropical deer (Cervus timorensis and Cervus unicolor) from Surabaya zoo were compared. The data were obtained from 1989 to 1996 calving time. The result showed that the mean calving date for Bawean deer is July 14th (SE = 8.3 days, n = 130), Timorensis deer being may 25th (SE = 11.0 days, n = 74), and Sambar deer being Juny 16th (SE = 26.2 days, n = 13). The calving time Bawean deer are spread equally between months, whereas Timorensis and Sambar deer tended to have a peak calving time with Timorensis Deer in July. Due to a small of calving record in Sambar deer, no conclusive result can be gathered.

Abstract

Experiment on salinity tolerance in Macrobrachium sintangense was conducted. The result showed that Macrobrachium sintangense has a wide salinity tolerance and all individuals could survive in the experimental medium up to 20 ppt salinity level, but no individuals could survive in the 35 ppt salinity more than 24 hours.
