Abstract

Bioactive are natural compounds that are easily found in plants and an alternative to use in many industrial products because of their rich benefits espspecially as a source of antioxidants. In the production of bioactive usually use the extraction method. However, some of the methods used still have shortcomings, especially in bioactive compounds that are thermolabile, the number of solvent compounds that are wasted have potential to damage the environment and the length of extraction time needed. This encourages the development of extraction methods that can answer these shortcomings, namely supercritical extraction methods where performance tests are needed on the design of supercritical extraction tools to ensure the stability and success of the design. These performance tests include leakage, pressure, temperature, and operating time to achieve supercritical conditions. Performance tests are carried out by flowing CO2 solvents, where the result of device design can achieve the minimum target of supercritical conditions which is 72.8 bar and 31.1oC and able to achive 90 bar and 35oC. It also obtained the average time it took to reach a supercritical state of 2:40:22. Based on leakage testing, leakage is a factor that affects the length of time required and hampered the achievement of supercritical conditions. In addition, heat loss and head loss factors which include pipe spacing, pipe connection, the size of pipe dimensions affect the duration and efficiency of tool design performance. This makes the tool identified for review of the tool design in the form of structural and functional design reviews.
