Abstract

This study aims to find of the effect of the water decoction of red betel leaf (Piper crocatum Ruiz & Pav) on blood glucose levels and cholesterol male white mice. The method used in this study deskripstif exploration using betel leaf stew and given to a white male mice are sonde at a dose of 0.13 ml / 20gBB, 0.13 to 0.39 ml / 20gBB 0.13 and 0.26 ml / 20gBB during seven days and examined glucose and cholesterol levels of the mice. Research results show that the water decoction of red betel leaf (Piper crocatum Ruiz & Pav) can lower blood glucose levels of male white mice were significantly (p <0.05) by ANOVA statistical analysis.

Abstract

Lead (Pb) is heavy metal which is naturally found in the earth's crust or originates from human activities, for example from combustion gas emissions in motorized vehicle engines. Republic of Indonesia Ministry of Health Number 1406 / MENKES / SKI / IX / 2002 concerning the examination of lead levels in human biomarker specimens human measurements of lead levels in the human body can be carried out by blood, urine and hair specimens. The purpose of this study is to determine the levels of lead metal in the urine of active smokers. The results of research on lead levels obtained on accuracy parameters, namely the accuracy test results for the method of wet destruction using HNO3 has an average recovery of 71.8% while using HNO3 added H2SO4 has an average recovery of 46.48%, precision test results are obtained % RSD method of destruction on HNO3 was 28.80%. If on HNO3 added 50.58% H2SO4, linearity test (r) 0.999, LoD value on HNO3 0.76 and on LoD HNO3 H2SO4 added. Based on the results of the study of verification of lead metal using wet digestion in the urine of active smokers not in the range of acceptability conditions it indicates that the method cannot be valid for use in the examination of lead in urine by the method of wet destruction in the active smookers.

Abstract

Hylocareus costarisensis more commonly known as red dragon fruit are beneficial as antioxidant and a source of natural pigments and potentially as antimicrobial. Journal of Food Research points out that the content of Phenol in the peel of red dragon fruit is greater than the the red dragon fruit itself.  Phenol contained in the dragon fruit peel can be useful as antimicrobial because it can lower the surface tension of the microbial. This study therefore aims to figure out whether there is an effect the phenol of Red Dragon Fruit Peel (Hylocareus Costarisensis) extract on the ability to block the growth of microbial patogent such as E.coli, Staphylococcus aureus, and Candida albicans and to figure out the compounds found in in the dragon fruit peel . This research employs statistical analysis experiment design by using One Way ANOVA test. The concentration of Red Dragon Fruit Peel extract used was 0,4 gr, 0,8 gr, 1,4 gr, 1,8 gr, 2,0 gr and positive control concentration thinning microbial 1,8 x 103Cell/ml. These studies demonstrated that the antimicrobial compounds in extract of  Red Dragon Fruit Peel is Acetic Acid, Formic Acid and Phenol. This research also indicates that the bigger dose of Red Dragon Fruit Peel, the greater power ability to block the growth. The ability to block the growth of microbial is statistically significant (p< 0,05) after giving of Red Dragon Fruit Peel extract
