Abstract

Traditional medicine cannot be removed from the lives of Indonesian people. In addition to very minimal side effects, traditional medicine using natural ingredients is widely used by the Sumbawa people because it is easy to obtain, easy to process, economical and has been carried out for generations. One of the natural ingredients that are widely used is sentalo leaf. This leaf is widely used as a medicine for torn wounds to stop the bleeding that occurs. Sentalo leaves are simply ground and then placed on the torn wound. Apart from being an antibacterial, sentalo leaves also have the potential as antidiabetic. The application of the sentalo leaf is expected to be more efficient, easy to apply by the community in health services for people with diabetes mellitus. The design of this study was True Experimental with treatment using RAL (Completely Randomized Design) and data analysis using the one-way ANOVA test. The results of the analysis of the antidiabetic effectiveness of sentalo leaf tea were shown by looking at the significant value of the one-way Anova test of 0.000 < 0.05 which could be concluded that there was a difference in the antidiabetic activity of sentalo leaf tea. The difference in blood glucose reduction in the treatment with Glibenclamide as a control group with Sentalo leaf tea 250 mg/kgBW was the same and not significant. So, it can be concluded that the optimum dose of sentalo leaf tea to obtain effective antioxidant activity is 250 mg/kgBB

Abstract

The progress of the traditional gold mining industry has a positive impact on improving the quality of life of the people, but on the other hand the progress of this industry has a negative impact on the environment. Mercury contamination from traditional gold mining occurs when the processing takes place which results in the holding tank being full, so that the tailings overflow and flow into the river, especially if it rains, then mercury contamination occurs in the surrounding environment. The purpose of this study was to analyze the effectiveness of a simple filtering device for activated coconut shell charcoal to reduce mercury levels in the waste water of the logs which included optimum contact time, optimum particle size, and optimum reuse. This type of research is True Experimental Design by providing treatment (contact time, particle size and repeated use of activated charcoal). It was concluded that the absorption of mercury waste with the highest efficiency value was activated charcoal particles measuring 35 mesh (0.5 mm) with an absorption percentage of 75.81%, the highest absorption percentage of mercury waste with a contact time of 180 minutes was 88.89%, and the optimal variation of the repetition of the use of activated charcoal is 5 times.
