KHOIRUL AJMI SIREGAR:Modification ofmechanicalcoffeeroastersequipment rotarytype, supervised byACHWILPUTRAMUNIRand SULASTRI PANGGABEAN. Roasting isan important stepin the production ofcoffee powder, whereinthe formation ofaromaanddistinctiveflavourof coffeeis enhancedat this stage. From nationalproductionof coffee beans,only 20% areprocessed andmarketedin the form ofsecondaryproductssuch as roastedcoffee, ground coffeeand instant coffee. This studywas plan to modifymechanicalcoffeeroastersequipment rotarytype. The study was conductedwith literature study, experiment, observationand testingof theequipment. Parameters observedwerethe effective capacity ofthe equipmentand economic analysis.Based on this research, it was summarized that the effective capacity of the equipment was2.96kg/hour. The economic analysis was as follows: basic costs for the first to the fifth year wereRp. 6703,04/kg, Rp. 6713,34/kg, Rp. 6724,63/kg, Rp. 6736,76/kgandRp.6749,81/kg respectively. The break even pointwas 264,54kg/year. The net present value was Rp. 125.277.927. The internalrate of returnwas 50%
