Gambir contains functional compounds that are included in the class of polyphenol compounds. The polyphenol compounds in gambir are mainly catechins, a natural substance that has antioxidant properties. The purpose of this study was to obtain catechin compounds from Gambir extract, to determine the solvent concentration and the right extraction temperature to obtain catechin compounds in Gambir, and to increase the selling value of Gambir latex in the Farmer community. To get the results of catechins in Gambir, this research was carried out using the infundation method. The yield of the extract was mostly found at a solvent concentration of 45% ethanol, a temperature of 105 oC and a time of 3 hours, namely 81%. Qualitative test using FeCl3 reagent can be seen that in the filtrate extracted from gambir there are catechins which show a blackish green color when dropped with FeCl3

The COVID-19 pandemic has significantly increased anxiety levels in the workplace. This research explores the potential of using aromatherapy candles made from coffee bean grounds as an effective way to reduce post-pandemic anxiety. In this experiment, the test panel was given aromatherapy candles using the Organoleptic, Aroma Durability, Burn Time and Hedonic Test Methods. The results showed that the use of coffee bean aromatherapy candles resulted in a significant reduction in the anxiety levels of the test panel. Aromatherapy candles made from coffee bean dregs have proven effective in reducing anxiety levels while working post-pandemic. This product has the potential to be a useful tool in improving mental wellbeing in the work environment and providing a positive experience for users
