<p style="text-align: justify;">Currently, many brands and types of skin whitening cosmetics can be found on the market. Not all products are safe for consumers. Illegal or non-licensed cosmetics from BPOM are suspect because unlisted cosmetics tend to contain harmful chemicals such as mercury (Hg). Mercury (Hg) was including harmful heavy metals. The use of mercury has been banned since 1998 through PERMENKES RI No. 445 of 1998, where mercury in small concentrations can be toxic. Negative effects of mercury such as allergies, skin irritation and permanent damage to the nervous system, kidney, brain and disrupt the development of the fetus, especially when used in high doses. The aim of this study was to know whether there is mercury content on bleach mask that sold in Martapura market in March 2017. This study used a descriptive method and the sample was taken by purposive sampling technique. There were 10 samples of face bleach mask that cost around Rp5.000,00 - Rp20.000,00. Based on the results of 10 samples taken at Martapura market, 3 samples contained mercury of face bleach mask. The conclusion of this study is that mercury still used as bleach on the facial in the Martapura market. Therefore, BPOM needs more supervision and intensive counseling about the risk of bleaching cosmetics containing mercury, so the consumer can be careful in choosing cosmetics.

Glucose is one of the clinical examination clinical parameters that are often done in the laboratory. This glucose examination uses enzymatic methods. Enzyme activity is influenced by several factors, namely temperature, pH, substrate level, enzyme level, and inhibitor. Glucose examination performed at a temperature of 20-25oC or 37oC, but there are still laboratories in the field that is less attention to the initial temperature conditions of this reagent. This study aims to determine the effect of initial temperature variations of reagents on blood glucose levels of enzymatic methods. The research used Quasi Experimental research method with Posttest-Only Control Group Design design. The sample of this research used serum of a respondent who had no history of Diabetes Mellitus disease with 4 replication at each treatment. The results of the study with the initial temperature of 10oC, 13oC, 16oC, 19oC, 22oC and 25oC (control) respectively of 62.71 mg / dL; 65,74 mg / dL; 72.45 mg / dL; 76.91 mg / dL; 89.12 mg / dL and 97.19 mg / dL, the results of this study showed an increase in glucose levels in each treatment. Based on the results of linear regression analysis obtained a significance value of 0.000 with α = 0.05, which means Ho is rejected, so it can be concluded that there is an influence of initial temperature variation of reagent on blood glucose level. For the next researcher can do research about the effect of the initial temperature of reagent 22-38 oC on blood glucose enzymatic method. And the influence of incubation time on blood glucose level of enzymatic method.
