Differences In Silver Human Education Rate Value Based On Hours Of Working In Semarang City

Abstract

Erythrocyte Sedimentation Rate (ESR) is the rate of deposition of erythrocytes in the a tube filled with blood that has been anticoagulated vertical and left for a certain time. Based on The use of materials that silver humans use screen printing paint as a dye and thinner as a paint solvent, The main chemical component of thinner is toluene. Toluene have a high severity of health impacts and if inhaled in the long term will cause an impact serious health problems and can affect LED values and sunshine at 12:00 to the afternoon can increases the risk of skin cancer and causes inflammation thus affecting the value of the LED. The purpose of this research to measure and analyze differences in sedimentation rate values blood on silver humans based on hours worked in the city Semarang. This type of research is descriptive with a cross design sectional. Samples were taken as many as 20 silver human samples during working hours at 07:00-12:00 and silver man at hours work at 12:00-17:00 in the city of Semarang then checked the value of the erythrocyte sedimentation rate using the LED examination method westergreen. The results showed the average value of LED silver man working hours 07:00-12:00 is 11.4 mm/hour, while the average value of the silver human LED in hours working hours 12:00-17:00 is 19 mm/hour. Data obtained then analyzed by statistical test Independent Sample T- Test. The results of statistical tests show that there is a difference with significance value 0.028. The conclusions of this research are: the difference in the value of the erythrocyte sedimentation rate in silver humans in hours working hours 07;00-12:00 and silver man working hours 12:00-17:00 in the city of Semarang.
