Abstract

Oyster mushroom is one of the most popular mushroom consumption cultivated in Indonesia. The cultivation process of oyster mushrooms is relatively easy , and also marketable because it has the nutrients and good nutrition. Oyster mushrooms is perishable foodstuffs. A few days after harvesting, oyster mushrooms will be amended, color changes to brown, becoming soft texture, and appeared unpleasant aroma. To overcome this, it is necessary to oyster mushroom processing innovation into alternative food products that have high sales value and longer shelf life. One alternative diversification of processed fresh oyster mushrooms is powdery mildew . To cultivate oyster mushrooms into powdery mildew, in this study focus to design a dryer oyster mushrooms with solar energy ( Solar dryer) and applying the grinder. Drier and grinder oyster mushrooms  was tested in groups of oyster mushroom farmers in the Tambak village Boyolali . Solar drier, can drying fresh oyster mushrooms with a capacity of 10 kg within a period of 50-72 hours. Oyster mushrooms grinder can be used with a capacity of 120 grams with a flouring 180 seconds

Abstract

PT.XYZ is a manufacturer of body bus which produce four type of bus that is big bus, medium bus, small bus, and mini bus. There is ten process to produce 1 unit big bus that is machine work, sub assembly, pra production, body assembly, metal finish, epoxy, putty, painting, trimming, and PDI (Pre Delivery Inspection). Based on the check sheet data summary from January to August of 2013, most major defect are in the putty process and based on the observation and interviews, there is product defects that pass inspection and entry process of painting. So, this study aims to identify the root cause of the defect and the escape of product defect from inspection. Root Cause Analysis method are used to identify the root cause of this problem. Using Root Cause Analysis method, RCA diagram showed that the root causes of defects are SOP that cannot be applied, the color of paint (epoxy) is less clear for inspection, poor lighting, lack of machinery, the wages of workers, and porous of fiber, while the root cause of the escape of product defect from inspection are SOP that cannot be applied, the color of paint (epoxy) is less clear for inspection, poor lighting, lack of machinery, the wages of workers, and lack of quality standards.
