Abstract

The practical use of plastic increasing the demand for plastic. Plastic waste is difficult to decompose, currently many efforts have been made to reduce this plastic waste. A plastic chopping machine is a tool used to produce shredded plastic items into small pieces of a certain size, which can later be used for further processing as a recycling effort. This study improves the design of an existing plastic chopper that focuses on increasing reliability and convenience by the user. The analysis was carried out using a fishbone diagram and the TRIZ design method. The research resulted in a number of causes for the emergence of problems in the operation of the plastic chopper and a new design for the tool, namely improvements in terms of the type of blade, type of motor, and size of the tool. Keywords: Improvement designing, plastic chopper, fishbone diagram, and TRIZ method.

Abstract

The number of human populations is increasing as well as daily needs and consequently increased the number of wastes that being produced including plastic waste. Indonesia itself consumed 17 kg/capita per year. Recycling the plastic waste is one of alternatives way to reduce waste, by melting the plastic waste using six heaters from electrical energy source. This research was conducted to obtain number of heaters that will be used in the injection molding process by considering the time consumed for the temperature of 50? - 210? C. The observation is being done by measuring the temperature and power supplied from 3, 4, 5 and 6 heaters and repeated for 3 times experiment. Based on the measurement data that has been carried out, it is found that the highest average power is the injection with six numbers of heaters consumed 956.80 W. The time measurement required to reach optimal temperature, for 3 number of heaters was taking the longest time which is 2842 Seconds. This condition is in line with the average of electrical power consumed to reach the optimal temperature is the using of the heaters 0.350 kWh. Based on three hypotheses that being done, the result shows that the Ha is accepted and there is significant influence between three models that being made.
