Abstract

ABSTRACT Urban area is dominated by land that functioned of the interest of economy and settlement, but only a few land allocated for wildlife. The butterflies was one of the wildlife that could be found in urban areas.The remaining habitat that can be used by butterflies assumed confined to the urban green space. Based on its life cycle, the butterflies having an initial phase (egg to larvae) is a phase which is generally require specific habitat. This research aims to determine the relationship between landscape characteristic and oviposition site preferences of butterfly. This research was conducted on April to June, 2014 at fifteen urban green spaces in East Jakarta by using descriptive survey technique. Landscape characteristics measured include area, perimeter, lawn area, closed vegetation area, open vegetation area, non vegetation area. Landscape characteristic not only measured from urban green space, but also measured from the area around urban green space within the scope of 100 meters buffer. Results show that there is a relationship between landscape characteristic and oviposition site preferences. Significant positive correlation between the abundance and area correlation coefficients rs (0,546), open vegetation area rs (0,758) and non vegetation buffer area rs (0,688). There was no significant correlation between the abundance with perimeter area, lawn area, closed vegetation area, non vegetation area, lawn buffer, open vegetation buffer and closed vegetation buffer.

Abstract

ABSTRACT Gigantochloa manggong, one of endemic bamboo plant in Indonesia is suspected have potensial as an exogenous antioxidant. Exogenous antioxidant can help the activity of endogenous antioxidant on the body when overtraining occurs. Antioxidant can be measured by catalase enzymes activity. This present study was carried out to determine the effect of maximum physical activity and leaf bamboo extract on catalase activity in liver organ of rats. This research used experimental method with completely randomized design (cRD). The test groups were the control rats (E0R0), rats induced leaf extract (E1R0), rats treated swimming activity (E0R1) and rats induced leaf extract and swimming activity (E1R1). Data were analyzed by the two-way ANOVA statistical test. Bamboo leaf extract turned out to be non-toxic and leaf extract contained flavonoids, alkaloids, triterpenoids dan saponins. Catalase units in the control group = 1.00 unit/ml, the group which induced leaf extract = 0.89 unit/ ml, the group which treated maximum physical activity = 0.78 unit/ml and the group which treated maximum physical activity and induced leaf extract = 0.56 unit/ml. Based on statistical test, catalase activity no effect (p> 0,05) on rats. It was concluded that maximum physical activity can’t decreased catalase activity, leaf bamboo extract can’t increased catalase activity and there was no effect between maximum physical activity and manggong bamboo leaf extract on catalase activity in liver organ of rats.

Abstract

ABSTRACT Recently the needs of antibacterial compounds is increasing. This is due to the bacterial resistence to common antibacterial compounds. coral and sponge-ssociated bacteria are potential producer of antibacterial compounds. This research was aim to obtain coral and sponge-associated bacteria that could produce antibacterial compound. coral associated-bacteria was isolated from Bitung and was isolated in Marine Agar by pour plate method. The antibacterial compounds were obtained by extraction using ethyl acetate and acetone. The antibacterial assay was performed by agar diffusion method using paper discs and was performed by testing with Staphylococcus aureus, Bacillus subtilis, Vibrio cholerae biotipe El Tor, and Escherichia coli. Total 37 isolate was isolated from corals and 25 isolate from sponge obtained from Selat Makassar. Based on the assay, only bacteria from sponge that showed antibacterial activity. Two sponge-associated bacteria, S.5-8 and S.2-1 NRBC were found to inhibit S. aureus. From those isolates, isolate S.5-8 produced bigger clear zone (2,6 mm) than S.2-1 NRBC (1,5mm). S.5-8 could hydrolize gelatine whereas S.2-1 NRBC showed positive result on oxidase test and was able to fement xilose and arabinose to produce acid. Key words: antibacterial activity, association, characterization, coral, isolation, sponge

ABSTRACT Hypertension is currently still a major problem in the world. In Indonesia, the number of hypertension tends to increase every year. One of the causes of hypertension is high salt consumption. This research was held to identify levels of Na+, K+, Cl- and total calcium in blood serum and to analyze the relationship among levels of Na+, K+, Cl- and total calcium with blood pressure. This study was conducted on March to May 2014 using a Crosssectional method. The result showed that Na+ level in hypertensive patient significantly higher compared in normotensive (p=0.000). K+ level in hypertensive patient significantly lower than normotensive (p=0.002). In addition, no significant between Cl- level (p=0.514) and total calcium level (p=0.417) in hypertensive patients and normotensive subject. There was a significant relationship between Na+ level with systolic blood pressure (rs=0.419) and diastolic blood pressure (rs= 0.455). There was a significant relationship between K+ level with systolic blood pressure (rs=-0.403) and diastolic (rs=-0.496). There was no significant relationship between Cl- level with systolic blood pressure (rs=0.071) and diastolic (rs=0.092). There was significant relationship between total calcium level with systolic blood pressure (rs=-0.393) and no significant with diastolic (rs=-0.306). In conclusion, there were significant differences in the level of Na+ and K+ in hypertensive patient and normotensive and a significant relationship among level of Na+ and K+ with blood pressure. There were no significant differences in the levels of Cl- and total calcium in hypertensive patient and normotensive and no significant relationship among levels of Cl- and total calcium with blood pressure.
