Abstract : Waste bank has problems in the storage of overload plastic bottle waste and even exceeds the storage capacity which should be approximately to 40 tons. Meanwhile, the size of the storage space on the waste bank is limited and even overload waste also takes up other storage space. The factor of this overloading is because the factory that takes plastic bottle waste is uncertain as taking plastic bottle waste at waste bank. The purpose of the plastic bottle waste press tool is to produce a design for the plastic bottle waste press. The process of designing this plastic bottle waste press will use a rational method. This method is used to obtain potential solutions and specifications for plastic bottle presses wishes of the supplier. In order for the designed tool to be comfortable to use, the tool design data will be combined with anthropometric data used to design the dimensions of the plastic bottle press tool that will be made. The rational method is a method that emphasizes a systematic approach in product processing. The results of this study showed that the design of the plastic bottle press using the rational method has been simulated to give good results where there is a decrease in the volume dimension reach 25%. There is an emphasis on plastic bottles when pressing using a press and it has been simulated that it can summarize the volume of plastic bottle waste.
