Hydration and Urine Quality in Workers Exposed to Heat Stress (Study on Ceramic Production Workers)

Workers in the ceramic industry were exposed to high heat stress every day, that can caused dehydration. Dehydration can be identified by urine color, urine pH, and urine specific gravity (USG). It is also necessary to know urine quality to indicate the health condition of workers, including by turbidity, presence of protein, epithelium, bacteria, and leucosit. This research is analytic and descriptive, with a cross-sectional. The population and sample are all workers in the ceramic industry center in Klampok Village, Banjarnegara Regency, Central Java, are 55 workers. The variables studied were heat stress, amount of drinking water consumption, dehydration status, and urine quality. Heat stress is measured using a heat stress meter, the amount of drinking water consumption is identified through interviews, dehydration status is measured through urine examination taken after work and analyzed in the Banjarnegara District Health Office laboratory, including color (with standard urine color indicator), pH (with digital pH), and the USG (with a refractometer). The quality of urine is seen from the turbidity, the presence of protein, epithelium, bacteria, and leucocyte levels that analyzed in the laboratory. Based on the urine pH no worker is dehydrated. However, based on the urine colour, 60% of the workers were dehydrated, and based on the USG, 76.4% of the workers were dehydrateded. The relationship between the amount of water consumption based on urine color, p value = 0,013, and based on USG p value= 0,863. 21,8% urine were cloudy, 91% positive protein, 91% positive leucosite, 96,4% normal epithel, 100% positive contains bacteria. There is a relationship between the amount of drinking water consumption with dehidration status based on urine color.
