Abstract

This study aims to determine the influence of leaf of Anona muricata L. powder against Sitophilus oryzae in rice during storage. This research is experimental research that uses experimental design with a basic design pattern randomize complete design. This study consists of four treatment groups (K0, K1, K2, and K3). K0 = control or no treatment; K1 = 10% (90 grams + 10 grams of rice powder leaves of Anona muricata L.); K2 = 20% (80 grams + 20 grams of rice powder leaves sirsak; K3 = 30% (70 grams + 30 grams of rice powder leaves Anona muricata L). Parameters measured the number of insects which declined during the 1 month storage. Data obtained in deskritif and analyzed statistically with inferensial test Fα = 0.05 followed by the LSD α = 0.05. Results of research indicate that the results of research show that the leaves of Anona muricata L powder. affect Sitophilus oryzae in rice during storage. Concentration of the most influential of Sitophilus oryzae in rice during storage is K3 (concentration 30%), the number of insects that are rejected 10 insects.

Abstract

This research is aimed to know the inhibiting capacity of methanol extact of Artocarpus communis Forst leaves to bacteria that causing infection on wound, i.e. P. aeruginosa and S. Aureus. Therefore, the sensitivity of both bacteria must be examined to methanol extract of Artocarpus communis Forst leaves. The sensitivity test was condsucted by paper disc method. The inhibition zone of methanol extract of Artocarpus communis Forst leaves was founded as a colourless zone that obtained after incubation for 24 hours. It is means P. aeruginosa and S. Aureus are sensitive to methanol extract of this plant. The inhibition zone is shown by methanol extract of Artocarpus communis Forst leaves toward bacteria coloni growth of P. aeruginosa and S. aureus that describingthe linear increasing of consentration from 5% to 20%. It is shown that Artocarpus communis Forst leaves contains the activity compounds as antibacteria, especially P. aeruginosa and S. aureus.

Abstract

This research have as a purpose to know the influence VCO to cholesterol content in hare blood rabbit (Oryctolagus cuniculus) masculine. Variable in this research that is gift VCO as free variable and cholesterol content in hare blood (O. Cuniculus) as variable trussed. This research represent the experiment research by using complete random device ( RAL) consisted of four treatment level namely A0 as control ( gift water), A1 ( gift VCO during 7 days ( ml / kg), A2 ( gift VCO during 14 days ( ml /kg)) and A3 ( gift VCO during 21 days ( ml / kg). Parameter observed is cholesterol content of hare blood. Result of research showed that gift VCO statistically do not have an effect on the reality to degradation of cholesterol content of hare blood (O. cuniculus ) masculine.

Abstract

Beauveria mildew is known as useful natural control agent, due to it’s infection potential agents for controlling insect. The range of its host covers broad range of insects order including Lepidoptera, Coleoptera, Hemiptera and Hymenoptera. In the past, the behavior of B.bassiana was identified based on morphological character, which is have weakness because of environmental effect so the fenotype performance does not manifest the genotype value. Another identification method can be used to complete morphological approach is identification based on physiological behavior (toxin production) and biochemical (protein and isoenzim) where the protein analysis and isoenzim, is order to minimize the influence of environment factor for identification. The research was conducted in Laboratorium Biology UNM, there is 11 isolates B.bassiana used in this research represent location and host. Isolates were analyzed by physiological and isoenzim using electrophoresis. The result of physiological character showed that out of 11 isolates characterized, there are isolates produced beauvericin, interestingly the rest isolates produced unknown on identified metabolites. Based on total band protein pattern and isoenzim showed that there are variation, isolates from the same area or district have more similarity characters than isolates from different area.

Abstract

Activity a protease enzyme hardly related to ability of mould elaborates protein component found on substrate that is casein. Temperature and hydrogen ion exponent is one of environmental factor influencing enzymatic activity. Initial step of determination of maximum hydrogen ion exponent by the way of giving treatment of initial hydrogen ion exponent so that obtainable and determined optimum pH B. bassiana subprovince Maros and sub-province Enrekang by seeing highest enzymatic activity indicator. Based on treatment of determination of optimum pH that is certain hydrogen ion exponent of which can cause highest activity to protease enzyme hence obtained by result that mould isolate B. bassiana sub-province Maros and also sub-province Enrekang both having enzymatic activity with optimum pH at hydrogen ion exponent 7 where enzymatic activity from each mould isolate successively that is 0,301 unit/mL/minutes and 0,682 unit/mL/minutes.
