Pineapple (Ananas comosus L.) is one of the Indonesian local fruits. Processing of pineapple into fruit juice is an effort to extend the shelf life and to increase the utility value of pineapples. Pineapple juice can be added with extracts from spices, such as turmeric, to enrich the content of functional compounds. The purpose of this research was to learn the physical and chemical properties of pineapple juice beverage with turmeric juice addition. The research used a non factorial Completely Randomized Design, with six formulations of pienapple juice and turmeric juice as treatments. The observed parameters were physical (viscosity and color include L*, a*, b*), and chemical properties (total soluble solid, total acid, vitamin C and total phenol). The results showed that the addition of turmeric juice significantly affected the increasing of a*, b* and total phenol values. Based on vitamin C and total phenol values, the formulation of 70 % pineapple juice : 30 % turmeric juice was the best treatment.
