dc.description.abstract	Stevia leaf is well known as natural sweetener with 300 sweeter times than sugar. Some previous studies showed that stevioside and rebaudioside A are glycoside contained in stevia leaf give the sweet taste. Stevioside can be harvested by solidliquid extraction. In this study, extraction process of stevia leaf was done in 1 Liter batch extractor by varying solvent and temperature. Three solvent (water, ethanol, methanol) and three temperature (45 °C, 50°C,55°C) variations were investigated. The results showed ethanol produce extract with the highest yield. Rising temperature would increase the yield and ash content of extract. Extraction with water produce the extract with the highest stevioside content because water has highest polarity of ethanol and methanol.	en_US
