Abstract

Sterculia quadrifida R.Br. is known with the name of Faloak. It is a plant whose bark has been containing several natural antioxidant compounds. Research shows that antioxidant compounds of Faloak extract can reduce free radicals content in liver organ of nila fish (Oreochromis niloticus) that is contamined by metals such as Pb, Cd and Hg. The concentration of metals is directly proportional with free radicals content of the organ, but free radicals content is inversely proportional with the concentration of faloak extract. Result of research indicates that faloak concentration of 16,00mg/mL is the most effective concentration in reducing free radicals content in liver organ of nila fish. Type and content of free radicals in the organ are identified with Electron Spin Resonance (ESR) test.

Abstract

Gamma radiation can causes cells damage, because the interaction between radiations with cells can produce free radical. The compound that can neutralize and catch free radical is called antioxidant. The objectives of this research were to analyze influence of gamma radiation and Curcuma xanthorrhiza extract to the SGPT level to the mice’s liver. This research uses eighty mices and they were divided into three group, negative control (K-), radiation non extract (R-) and extract plus radiation (R+). The doses of treatment of Curcuma xanthorrhiza extract are 1.4 gr/kg body weight; 2.0 gr/kg body weight; 2.6 gr/kg body weight; 3,2 gr/kg body weight and 3.8 gr/kg body weight, while the exposure of gamma radiation are given during 10 minutes, 20 minutes, 30 minutes, 40 minutes and 50 minutes. The measuring of SGPT level in mice’s serum is done by using blood analyzer. The results showed that free radical can damages liver cells and breaks cell wall, so SGPT level in blood to be high. In a row of increasing of Curcuma xanthorrhiza extract dose, then SGPT level to be low.

Abstract

The absorption visible light spectrum by chlorophyll cause excited electron. The transition of electron in photosynthesis process result electrical potential difference response which can be utilized to spur metabolism process in the plants itself. This research used the seedling of Glycine max (L.) and the varietas is sindoro. The measurement of the potential difference response is done by adding of visible light (red, yellow, green, blue and violet) alternately to the bean sprouts of Glycine max (L.) Merill. The light distribution is being done for 1 second, 5 second and constantly. The result of the research showed the effect of the visible light distribution constantly in the photosynthesis process. In the red light occurs maximum potential difference response. In peak I resulted -147,3 mV and peak II resulted -137 mV. The minimum potential difference response is resulted by green light. in peak I resulted -68,8 mV and peak II resulted -56,75 mV. The effect of the visible light distribution during any time in the photosynthesis process. In the red light occurs maximum potential difference response. In peak I resulted -119,2 mV for 1 second and -146 Mv for 5 second. In peak II resulted - 112,3 mV for 1 second and -125,5 mV for 5 second. The minimum potential difference response is resulted by green light. In peak I resulted -64,75 mV for 1 second, -69,5 mV for 5 second, and in peak II resulted -55,9 mV for 1 second and -56 mV for 5 second.
