The tissue of plant preparation has not been owned by some school because the price of plant preparation is relative expensive and to make it self constrained price of substance from dyeing chemistry, then it take dyes substitute which have the same function with synthetic dyes. The utilization of natural dyes are cheap and easy to get it, so the use of leaves of teak young as alternative of natural dye can be used to replace dyes synthetic. This research was descriptive qualitative research. The purpose of this research is to analyse the quality natural dyes of teak leaves extract also develop biology learning resource. This research is experiment method with Complete Randomized design with 2 factors treatment that was solvent type (citric acid 14% and etanol 96%) and long soaking (24 hour, 25 hour and 26 hour) also safranin as comparison. The manufacture plant preparation used sliced transverse method to chili plant stem with dyes of teak leaves extract. From the result of research, plant preparation quality of tissue which the better and closer safranin dyes was used by dyes of teak leaves extract with etanol solvent 96% with long soaking 26 hour
