Abstract
Bioactive substances are compounds that are easily found and found in plants, especially in the fruit, roots, skin, and so on. Due to its increasing utilization, a process is needed to take bioactive substances in plants with an easy and efficient process. The extraction methods of bioactive compounds themselves vary, ranging from physical methods to chemical methods. One other extraction method besides those mentioned is extraction using supercritical phase carbon dioxide (CO2). The supercritical phase can be obtained by raising the temperature and pressure on carbon dioxide (CO2). Supercritical carbon dioxide (CO2) phase can later be utilized to extract bioactive materials. Various schemes of supercritical extraction designs, in this design an extraction machine scheme with a separator is used. In this research, testing was carried out by operating a tool without bioactive ingredients. The parameters reviewed in engine performance testing are leak tests, length of time, pressure strength, and engine power usage. Supercritical extraction machine results are obtained using the extraction machine scheme with a separator, in this scheme it was chosen because it can be separated quickly by reducing pressure, lowering temperature, or both. The working mechanism of the supercritical extraction machine is operated into four stages, namely heating, pressing, extraction, and separation. As for the performance of the supercritical extraction machine, the machine use variety of times to heat or making supercritical phase, it can be concluded that the engine performance has not been maximized.
