Abstract

The coffee machine is a very useful kitchen tool from ancient times. It is designed to facilitate coffee making. The more modern the more sophisticated coffee machines are designed but the coffee machine is difficult to bring together because it has a large size and weight. This will lead some problem to coffee lover especially traveler. Therefore, this product is designed to solve the problem so that the coffee machine is easy to carry anywhere. The size of this product is the same as the size of 250 ml bottle of mineral water. This product is designed based on three types of coffee machine which are Moka Pot, French Press and Vacuum Coffee Maker. Then, some morphological chart is carried out to choose the best design for this coffee machine. The design of this coffee machine is drawn using the "Solidwork" software. Once this machine is ready or created, it will be tested and ensured to function as it should. In addition, this coffee machine has a unique mechanism in which it uses the infusion mechanism. This mechanism responds by heating the water at the bottom of the machine coating until it shrivels. The boiling water will be pushed to the top by a small tube by the water vapor pressure. The small tube connects the hot water course from the bottom of the coffee machine to the middle containing coffee powder and then to the top of the coffee machine. The coffee machine has been studied in terms of the time required to produce coffee water and the temperature of coffee produced by using three different types of heat sources namely small bunsen burner, spirit lamp and candle. The result that is obtained after trying and analyzing this product is recorded and tabulated. Small bunsen recorded the least amount of time in producing coffee water of 6.31 minutes and produced the highest temperature water temperature of 92.2˚c compared with spirit lamps and candles. In conclusion, the objective of this project has been achieved. The personal compact coffee machine for traveler is successfully designed and developed based on the requirements. This coffee machine has been named a Traveler’s Portable Coffee Machine.
