This study aims to find the tannin content with qualitative and quantitative testing. The design used is a randomized block design with an extraction time of 30 minutes, 40 minutes, and a temperature of 60 °C, 70 °C, and 80 °C treatment repeated 4 times. The results showed that the highest tannin content obtained at the extraction time of 40 minutes at a temperature of 80 °C with a tannin content of 11.55%. The treatment that gave the best results obtained in 40-minute long treatment with a temperature of 70 °C with a tannin content of 10.90%, solubility 29.48% and a pH of 5.80.
