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

This research was carried out on one of the fertilizer industry. This industry have numerous itemof machine spare part. The problem concerned with machine spare parts controlling which is theordering of them are done separately, that makes inventory cost and order frequency become quite high. Therefore, inventory control of machine spare part will be done by using a coordinated ordering system with model of can-order policy. Parameters determination (S,c,s) was held on 7 items of machine spare part that was ordered from 1 supplier with using algorithm can order policy. Then, the total cost of inventory was calculated based on parameter of can order and will be compared with existing company system using monte carlo simulation. This comparing result shows the model of can order policy is more efficient to control machine spare part inventory which saving 52 % than the total inventory cost using existing company system.
