The increase in global coffee consumption causes an increase in the amount of waste. One of the components of coffee grounds waste that is thrown into the environment is tannin. Tannins are applied in various industries, including the textile, pharmaceutical, cosmetic and food industries. The research aims to observe the effect of temperature and extraction time on tannin content using the ultrasonic extraction method. Extraction was carried out using 80% ethanol solvent with 2 variations, namely, variations in extraction temperature (40, 45, 50, 55, and 60) ˚C and extraction time (10, 20, 30, 40, 50, and 60) minutes. Extracts containing tannins were then analyzed qualitatively and quantitatively. Tannin levels were tested qualitatively using FeCl3 and Gelatin, and quantitative analysis was carried out using a UV-VIS Spectrophotometer. The functional groups contained in the tannin extract were tested using the FTIR (Fourier Transform Infra Red) Spectroscopy method. The highest tannin content was obtained at an extraction temperature of 55°C and an extraction time of 10 minutes, amounting to 215.85 mg/g-1. The tannins contained in coffee grounds extract are condensed tannins.

The use of metal mordants in fabric dyeing can harm the environment and health, so it is necessary to look for natural mordants that are more environmentally friendly. The utilization of Simpur Air leaves (Dillenia suffruticosa) as a biomordant is one of the efforts to produce a more environmentally friendly tannin mordant. D. suffruticosa has been reported to contain tannin compounds in all parts of the plant. However, scientific evidence of differences in the total tannin content of methanol extracts of D. suffruticosa leaves with various extraction methods have not been found so far. This study aims to determine the effect of different extraction methods on the yield value and total tannin content of methanol extracts of D.suffruticosa leaves using UV-Vis spectrophotometric method at a wavelength of 755.8 nm with Folin Ciocalteau reagent. D. suffruticosa leaves are extracted by using three methods, namely maceration, soxhletation and reflux. Tannic acid is used as a comparator. The results show that the yield value of D. suffruticosa leaves extracted by maceration, soxhletation and reflux methods were 8.35%; 12.26%; and 25.24%, respectively. The total tannin content of methanol extract of D. suffruticosa leaves with maceration method is 0.15% ± 0.007; soxhletation is 0.18% ± 0.007 and reflux is 0.21% ± 0.016. Based on the results of the data analysis, the significance value <0.05 was obtained. It can be concluded that the extraction method affects the yield value and total tannin content of methanol extract of D. suffruticosa leaves.

The use of synthetic dyes as color enhancers or generators has caused various environmental and health problems. Plant tannin biomordants offer an alternative solution to address these issues. The sample used in this study were Cengkodok (M. malabathricum) plants that grow wild in places that get enough sunlight such as shrubs. Phytochemical screening on various parts of the cengkodok plant revealed that the highest tannin content is found in the leaf. However, until now there has been no scientific evidence that presents differences in tannin levels in cengkodok leaf with various types of solvents. This study aims to determine the yield and total tannin content of cengkodok leaf extract obtained through maceration process using methanol, ethanol, and ethyl acetate solvents. The extract yield was determined by comparing the weight of the dry extract with the powdered cengkodok leaf material. The total tannin content was analyzed using UV-Vis spectroscopy at a wavelength of 755.8 nm with Folin-Ciocalteu reagent and sodium carbonate. Tannic acid was used as a reference. The research results showed that the yield values for Cengkodok leaf extracted with methanol, ethanol, and ethyl acetate were 5.05%, 4.72%, and 1.59%, respectively. The total tannin content of cengkodok leaf extracts with methanol, ethanol, and ethyl acetate solvents was 0.47%±0.04, 0.37%±0.01, and 0.19%±0.04, respectively. Based on this research, it can be concluded that methanol is the most effective solvent in extraction and determination of total tannin content of Cengkodok leaf extracts.
