Abstract

Areca catechu (Areca catechu. L) contains many chemical components, namely, pectin, cellulose, hemicellulose, lignin, pectin oxalate and flavonoids. Tannins are very complex organic substances and consist of phenolic compounds. Tannins are obtained by extraction with water and ethanol solvents because tannins can dissolve with these solvents. This study aims to identify tannin compounds in areca nut using ethanol as a solvent. This research is a laboratory experiment with an extraction process using the maceration method. The areca nut is dried and mashed and then sifted. Then the powder was macerated with 70% ethanol solvent for ± 24 hours, then evaporated and then tested qualitatively and determined the type of tannins. The results showed that areca nut extract was positive for tannins and the type of tannin was condensed tannins.

Abstract

Gallons of refilled drinking water usually don't run out in a single use but run out in a few days or even up to 1 to 2 weeks, depending on usage, and stored at room temperature (27-29 °C). Drinking water that is stored for a long time will allow the growth of microorganisms which are influenced by environmental factors, namely temperature conditions and oxygen supply during storage. This affects the pH and total organic content of drinking water. Inspection of the quality of water products according to the Regulation of the Minister of Health of the Republic of Indonesia Number 492/MENKES/PER/IV/2010, which is a maximum organic matter content of 10 mg/L. According to chemical parameters, drinking water must not contain inorganic and organic substances exceeding the standard with a pH value between 6.5-8.5. The purpose of this study was to determine the levels of organic substances in RO (Reverse Osmosis) refill drinking water. This type of research is a laboratory experiment using purposive sampling technique. The results showed that the average organic content of refilled drinking water with a storage period of 0 days was 1.839 mg/L, 3 days was 2.57 mg/L, and 6 days was 5.28 mg/L. Thus, the levels of organic substances in drinking water are based on storage time of 0, 3, and 6 days using the spectrophotometric method according to the maximum drinking water quality standard.
