Indonesia has a large amount of rainfall and can be used as raw water of drinking water. A Radio frequencyplasma system radiation can produce active compounds (•OH^-, •O, •H⁺, H₂O₂, O₃ etc) in water, the active compounds have a high oxidation potential and can kill microorganisms present in water (fecal coliform, total coliform and Salmonella). Plasma system is one way to produce drinking water in terms of health aspects because in the process the tool does not contact with the material directly, so the possibility of contamination is small. The purpose of this study is to remove microorganisms in rainwater using plasma radio frequency system continuously. Samples will be filtered using pure and mix polypropylene cartridge filter with a pore size of 1 μm and then contact in plasma system. Plasma is generated by applying a frequency of 0,16 MHz through a glass reactor with a thickness of 2 mm which is wrapped by a 1 mm copper wire. The results show that the removal microorganism in rainwater using plasma coupled with filtration using pure polypropylene filter reached 100% for total coliform, fecal coliform and Salmonella. While the removal microorganisms in rainwater using plasma coupled with filtration using mix polypropylene reached 70–100%, 85–100% and 80–100%, for total coliform, fecal coliform and Salmonella, respectively.

印度尼西亚降雨量大，可作为饮用水的原水。A 射频等离子系统辐射可以在水中产生活性化合物（•OH ^-、•O、•H ⁺、H ₂ O ₂、O ₃等），这些活性化合物具有很高的氧化电位，可以杀死水中存在的微生物（粪便大肠菌群、总大肠菌群和沙门氏菌）。等离子系统是一种从健康方面生产饮用水的方法，因为在此过程中工具不直接与材料接触，因此污染的可能性很小。本研究的目的是利用等离子射频系统连续去除雨水中的微生物。样品将使用孔径为 1 μm 的纯和混合聚丙烯筒式过滤器过滤，然后在等离子系统中接触。等离子体是通过施加 0.16 MHz 的频率通过厚度为 2 mm 的玻璃反应器产生的，该玻璃反应器由 1 mm 铜线包裹。结果表明，等离子体结合纯聚丙烯过滤器过滤的雨水中微生物对总大肠菌群、粪大肠菌群和沙门氏菌的去除率均达到100%。. 而使用等离子体结合使用混合聚丙烯过滤的雨水中微生物的去除率分别达到了总大肠菌群、粪便大肠菌群和沙门氏菌的 70-100%、85-100% 和 80-100% 。
