Abstract
Coffee borer beetles (Hyphothenemus hampei) generally bore the coffee fruit which its endosperm has already hardened, and thenthere is a disability at coffee bean causing a damage of chemical quality, while the flavor of coffee is influenced by combination of chemical compound components contained in the coffee bean. This study aims to see the changes in levels of caffeine, fat and water in coffee due to the attack of coffee borer beetle (H. hampei). The levels test of caffeine, fat and coffee water were carried out in the laboratory of Baristan Aceh and the farm laboratory of agriculture faculty of Syiah Kuala University. The results of the test show that H. hampei pests can cause the increase of caffeine level in the coffee beans up to 1.41%, decrease of fat level in the coffee beans up to 15, 81% and the increase of water level in the coffee bean up to 2.58%.
