Abstract

Low birth weight (LBW) are most likely a cause of increasing the number of infant mortality rate. The incidence of LBW related to many factors such as maternal health, fetal, and environmental factors. Early detection to see fetal growth during pregnancy is to estimated fetal weight. The purpose of this research was to find out the correlation of maternal age, maternal education, maternal occupation, history of parity and nutritional status with estimated fetal weight. The type of research used was analytical observational study with cross sectional approach and collected using questionnaire with total samples of 72 pregnant women. The result of this research showed that there was correlation of maternal age (p=0,04), maternal education (p=0,012), history of parity (p=0,003), nutritional status (p=0,012) with estimated fetal weight. There was no correlation of maternal occupation (p=0,327) with estimated fetal weight. The concludes of this research was pregnant women with non-risky age, higher education, parity 2-3 times and good nutritional status tended to have the weight of the fetus conceived according to gestational age, while maternal occupation would not necessarily affected the estimated fetal weight.

Abstract

The problem of coal dust due to the accumulation and loading of coal to barges for shipping has not been studied optimally. This study aimed to investigate the characteristics of coal dust and the air quality of the three coal industries. Coal dust characteristics were tested through proximate analysis, XRD, XRF, and SEM. Meanwhile, air quality is viewed from exposure to gases that cause emissions (CO, NO2, and SO2), PM10 and TSP, humidity, and temperature. Coal dust consists of SiO2, Al2O3, and Fe2O3 as the main components with high ash. Exposure to SO2 and TSP can potentially exceed the annual threshold value.
