Abstract
Normal 0 false false false IN JA X-NONE Abstract One strategy attempts to reduce dependence on primary commodity markets are overseas market expansion and development of secondary products. In the secondary product processing coffee beans is required of supporting equipment to facilitate these efforts. Research Center for Indonesian Coffee and Cocoa has developed coffee bean roaster. However, there are still many people who do not know about the technical aspects of roaster machine type of rotating cylinder so that more people use traditional ways to roast coffee beans. In order for the benefits of this machine is better known society it is necessary to study on the technical aspects. The purpose of this research is to evaluate the technical performance of the coffee beans roaster machine type of rotating cylinder. These include the technical aspects of work capacity of the machine, roasting technical efficiency, fuel requirements, and power requirements of using roaster machine. Research methods are including data collection, calculation and analysis. The results showed that the roaster machine type of a rotating cylinder has capacity of 12.3 kg/hour. Roasting efficiency is 80%. Fuel consumption is 0.6 kg. The calculated amount of the used power of current measurement is the average of 0.616 kW.

Summary
Indonesia is become one of the largest coffee producers in the world after Costa Rica and Brazil. On the one hand, increasing the production has a positive contribution to the increasing in export earnings. On the other hand, an anticipatory action needs to be done to deal with a drastic decline in prices that occurred from time to time due to excess supply of coffee beans in the world market (USDA, 2000). One strategy attempts to reduce dependence on primary commodity markets are overseas market expansion and development of secondary products. Development of coffee valued secondary products will provide some economic incentives for countries including the increase value added greater agricultural products, employment opportunities in rural areas, development of related industries and increased per capita coffee consumption in the country which is currently relatively low ( USDA, 2000)
