    The usage of syntethic colorants today can result wastes containing heavy metal that can cause health troubles such as cancer, exhalation syndrome, irritating eye, etc. Meanwhile, natural colorant is easily decomposed by bacteria on soil and doesn’t contain heavy metal so it can be good alternative of colorant respectively. ‘Buah mangsi’ (Phyllanthus reticulatus) is one of the natural colorant as it contains anthocyanin pigment. It has not been utilized optimally so far. The aim of this study was to design natural colorant extractor by its optimal variable that gave effectivity in operation with focus getting the optimal capacity of extractor, determining the best impeller, and the rate of the extractor motor that gave the highest natural colorant extract. This natural colorant study of ‘buah mangsi’ held in Laboratorium Proses Teknik Kimia, Fakultas Teknik Universitas Sebelas Maret Surakarta. ‘Buah mangsi’ (Phyllanthus reticulatus Linn.) was one of potential natural colorant resources. The method used in this study was leaching (solid-liquid extraction). This extractor of ‘buah mangsi’ was designed consisting of agitator tank, screen, and motor. This study produced a appropriate extractor. The result showed that the the marine propeller gave the highest rendemen as much as 11,975% b /b at 500 rpm while the capacity of extractor didn’t influence much to rendemen of the extraction.
