Abstract
Abstract. This practice uses a distillation device from household waste. The water used for the clarification process is the sewage water from the ditch in Tomba Village in Baubau and the sea water used is sea water from the sea of Baubau city. This research method is ADDIE development (Analysis, Design, Development, Implementation, and Evaluation). However, this research method only did until the development step. In necessity analysis, the researcher analyzed literature study and field study. After the stages of next analysis stage is the design stage, researchers design a practicum design and then consulted with a competent lecturer in the field of water purification and processing of sea water into fresh water. After the design stage then carried out the stages of development, the researchers conducted the optimization process as much as 3 times. During the optimization process a feasibility assessment of practical design is undertaken. The assessment was conducted by 5 observers of postgraduate chemistry education students. Indicator of practical feasibility assessment that is related to mixed separation material, equipment resistance, practicality of the tool, accuracy of equipment and student safety and tool capability of separation is directed from the distillation result in terms of smell and taste. The result of percentage of process of appraisal feasibility evaluation 90,90%, 90,90%, 93,18%, 93,18% and 93,18%, respectively. The percentage is included in the category of excellent interpre- tation, based on the result of the feasibility assessment, the practical design is ready to be implemented in the learning of mixed separation material.
