Limbah merupakan produk samping yang biasa dibuang karena dianggap tidak memiliki nilai tambah. Limbah padat dari ampas daun sereh wangi tersebut jika diolah dengan benar maka dapat dijadikan sebahai bahan pewarna alami terhadap suatu produk yang sudah mulai sulit didapatkan karena industri lebih memilih menggunakan pewarna sintetik. Pengolahan limbah padat ini, dapat dilakukan dengan mengekstrak ampas dengan menggunakan pelarut tertentu. Pada penelitian ini digunakan perbandingan yang berbeda yaitu 30 ml : 1 ml : 10 ml :, 20 ml : 1 ml : 20 ml, dan 10 ml : 1 ml : 30 ml. Ekstrak dari ampasnya tersebut kemudian di pekatkan untuk menguapkan etanol yang terkandung. Hasil evaporasi dianalisa kadar antosianin dengan menggunakan spektrofotometer. Pengolahan data hasil analisa menggunakan statistik dengan metode Analysis Of variances (ANOVA) One Way. Berdasarkan hasil penelitian campuran pelarut yang optimal untuk mengekstrak antosianin yaitu pada perbandingan etanol : HCL : Aquadest = 30 ml : 1 ml : 10 ml. Perbandingan campuran pelarut tersebut dapat mengekstrak antosianin sebsar 239,47 ppm hasil ekstraksi tersebut merupakan hasil yang paling besar dibandingkan dengan campuran pelarut lain yang digunakan. Analisa ANOVA One Way menunjukkan bahwa ketiga sampel memiliki perbedaan secara nyata dan hasil ekstraksi yang optimal pada perbandingan pelarut etanol : HCL : Aquadest = 30 ml : 1ml : 10 ml.

Waste is commonly disposed of by-products because they do not have added value. Solid waste from the waste leaves the citronella if treated properly, it can be used as natural dyes sebahai to a product that is already getting hard to come by since the industry prefers to use synthetic dyes. The solid waste treatment, pulp can be done by using a solvent to extract specific. In this study used a different ratio of 30 ml: 1 ml: 10 ml:, 20 ml: 1 ml: 20 ml, and 10 ml: 1 ml: 30 ml. Extract of the pulp is then in pekatkan to vaporize ethanol contained. The evaporated analyzed for levels of anthocyanin by using a spectrophotometer. Data processing analysis results using statistical methods Analysis Of variances (ANOVA) One Way. Based on this research the optimal solvent mixture to extract anthocyanin ie at a ratio of ethanol: HCL: Aquadest = 30 ml: 1 ml: 10 ml. Comparison of the solvent mixture can extract anthocyanins extracted sebsar 239.47 ppm is the result of the greatest compared to other solvent mixture used. One Way ANOVA analysis showed that all three samples have real differences and result in optimal extraction solvent ratio of ethanol: HCL: Aquadest = 30 ml: 1 ml: 10 ml.
