Abstract

Dye are organic compounds used to give colour to a subject. The use of colour on the preparations aims to sharpen and clarify the image of cells, making it easier to examine under a microscope, especially in the division of cell. Application of vegetable materials containing anthocyanins that can be used as natural dye preparations. Red dragon fruit skin has anthocyanin content is high, potentially as a dye alternative preparation. Research aims to find out the quality of Allium cepa preparations using dye of aquadest extract and citric acid. The method used was the squash method and used a complete randomized design (CRD), with two treatment factors are solvent type (aquadest and citric acid 10%) and long staining (1 hours, 2 hours, 3 hours). The result were analyzed using qualitative descriptive method which includes clarity of preparation and colour contras. The result showed that the quality of mitosis Allium cepa preparations with dye extract of red dragon fruit skin aquadest better than citric acid extract with a maximum duration of 2 hours of staining. The length of staining preparations affects the contrast of resulting colour. Staining for 3 hours produces a color that is less contrast than pink to brown.
