Abstract

This pneumatic system tofu press machine is a press machine that is used to compress tofu starch with a capacity of 50 kg to make tofu that is ready to be marketed. The pneumatic system tofu press machine is made to make it easier to press tofu. Previously, tofu was pressed manually, namely by using a stone as a tofu press which resulted in the length of the tofu compaction process. Pressing with stones can also cause work accidents. This tofu press machine uses pneumatics as a punch driver which will press the tofu. The way this tofu machine works is by pressing the on button on the machine then the punch will move down towards the tofu essence and press the tofu. Punch paused for a moment to make sure the tofu blended in perfectly. Then press the off button on the machine to return the punch to its original position. This pneumatic system tofu press machine can reduce work accidents, lighten work, shorten processing time and is also more hygienic because it uses air as a punch driver.

Abstract

The quality of a product determines the level of market demand. This paper discusses the determination of the quality level of plastic molding with the sigma level method which uses the Box Plot to determine the desired quality limit. The purpose of this research is to determine the level of quality of product using statistics. The object of this research is to determine the weight variation of the souvenir of PNP logo with a weight indicator. The experiment were carried out on 200 samples taken at random.Then each sample is numbered from 1 to 200. Each sample is weighed carefully. The results obtained were processed using a box plot to obtain the numbered of rejected samples from 200 samples that were weighed. The result of data processing obtained 19 reject products from 200 products tested. From this data there are 9,5% of products that do not meet the desired specifications. Furthermore, the sigma level is determined from the results of data processing using a box plot. DPMO of 9.5% is 95000 Defects per Milion Opportunities. The result of determining the sigma level is 2.8 Sigma.
