<![CDATA[Has realized a detection tool quality coffee beans to coffee papain using the principle of measurement of the capacitance. The working principle of this tool is to use a conveyor which serves to select the color of coffee beans and a capacitive sensor to measure the capacitance value of the coffee beans. The research that has been conducted producing good quality coffee beans that is red and has a rated capacitance range between 160 fF -170 fF. The coffee beans that has been retrieved is evidenced by the conventional method of soaking in water, where the range of 160 fF -170 fF the coffee beans submerged. Compared to manual, this technique is more effective because it can generate data capacitance can be used as a reference to identify the range of good quality coffee beans and of poor quality.           Keyword: capacitance, range 160 fF -170 fF, quality coffee bean]]>
