ABSTRACT PLANT INDIGOFERA AS RAW MATERIALS IN NATURAL BATIK Darban Haryanto (1) Ellen Rosyelina Sasmita (2) darbanharyanto@ymail.com Indigofera plant is one type of plant where the leaves can be used as natural coloring agents for coloring batik cloth which has a prospective future. Yogyakarta as the center of batik most of the batik industry for its coloring material uses chemical dyes. The advantage of this chemical textile dye is that it is inexpensive and has a high stability compared to natural dyes, in addition to the diversity of colors available and the continuity of the guaranteed material so that it is preferred by consumers. But since there is a prohibition on using chemical dyes, especially from azo species in the Netherlands, Japan and Germany, it provides an opportunity to find a substitute for chemical batik colors using natural batik dyes. Dyestuff-producing plants grow in Indonesia, more than 150 types of plants that produce dyes that can be extracted from roots, stems, flowers, bark and others. Among these types of plants producing color is Indigofera. The leaves of this plant can be extracted which can give a blue color. Indigofera plants are relatively easy in their cultivation and do not require fertile land requirements, so that the marginal land of these plants can be cultivated. Indigofera plants are resistant to pruning, so at the age of 4 months the leaves can be utilized to be processed into indigo paste that produces blue color (tom). In its life cycle that can reach 2 years, plants can be taken as many as 6 times pruning. Indigo leaf processing can be done by extracting this plant with the following steps: the leaves are immersed in a soaking tub and then the immersion water is oxidized, the result is a settling paste. This paste is then drained to reduce the water content. Indigo paste produced can be used for natural batik dyes Keywords: batik, natural dyes, Indigofera (1) Lecturer in the Department of Agricultures Agriculture Faculty UPNVY (2) Lecturer of the Department of Agricultures Agriculture Faculty UPNVY Paper presented at the international seminar ICGAI Faculty of Agriculture, Yogyakarta National Development University
