Abstract

Hypertension is a generative disease which becomes a health problem throughout the world. Its prevalence in 18 years-old females is higher than that of males. The data from Riskesdas in 2013 revealed that the prevalence of hypertension in females was 28.8% and in males was 22.8%. it does not attack the aldery; it only attacks young adults. Uncontrolled hypertension can cause various complications in the entire organs and reproductive health in pregnancy and childbirth of young adult females. Goals: The research used observational analytic method with case-control design. It was conducted at Teladan Puskesmas, Medan from March until September, 2017. Method: The population was 96 hypertention young adult females who had been pregnant and visited Teladan Puskesmas. 48 of them were in the case gruop and the other 48 were respondents were in the control group (using total sampling technique). The data were analyzed by using univariate analysis, bivariate analysis with chi square test, and multivariate analysis with logistic regression test. Result: The result of the research showed that there was no influence of history of family on the incidence of hypertension (OR=1.6 95%CI= 0.683-4.1444), while obesity (OR=9 95%CI= 2.876-28.494), physical activity (OR=3.6 95%CI= 1.543- 11.626) had the influence on the incidence of hypertension. Obesity was the most dominant risk factor which influenced the incidence of hypertension in young adult females. Conclusion: It is recommended that young adult females keep their food intake stable with balanced nutrition and regular sport. Hypertension women should use hormonal contraceptive devices and have their blood pressure examined regularly so that complications can be detected early in preparing for pregnancy.

Abstract

One of the problems with fast-growing wood is the low density, which causes poor mechanical properties, so a densification process is carried out to increase the wood's density, surface hardness, and strength. In this study, the delignification process using NaOH was carried out at variations of 12.24, and 48 hours and then continued with the thermomechanical densification process. This study decreased lignin content in delignification simalambuo wood from 30% to 4%. The value of the Modulus of Rupture, Modulus of elasticity, and surface hardness increases with increasing immersion time during the delignification process. The highest values of Modulus of Rupture, Modulus of elasticity, and surface hardness were obtained by simalambuo wood soaked for 48 hours, namely, 2828.23 kg/cm2, 97.47 kg/cm2, and 256.73 kg/cm2.
