gilingan, kadar air dan organoleptik oleh panelis yang expert dibidangnya. data yang didapatkan kemudian akan dianalisa. hasil penelitian menunjukan bahwa perlakuan perbedaan kehalusan bubuk kopi yang dihasilkan mesin penggiling conical burr mill memberikan pengaruh nyata pada kapasitas mesin, rendemendan kadar air. ditinjau dari aspek perforrma mesin diketahui perlakuan pada tingkat kehalusan 5 mesh merupakan perlakuan terbaik pada pengujian mesin conical burr mill dengan menunjukan nilai 20.3203kg/jam pada kapasitas mesin, 9.1668% pada rendemen, 1.9706% pada kadar air bubuk kopi. sedangkan ditinjau dari mutu bubuk kopi diketahui perlakuan pada tingkat kehalusan 10 mesh merupakan perlakuan terbaik pada pengujian organoleptik dengan skor 83.25 kata kunci :kopi, mesin penggiling, conical burr mill abstract: therefore the purpose of this research is to know the performance testing of the machine coffee grinder with the treatment difference fineness. the materials used in this research is the arabica bean coffee obtained from bener meriahthen roasted with a temperature of 170 ° c for 25 minutes.treatment that is done is the difference fineness with 3 degrees of fineness is measured with sieve mesh size 35, mesh size 10, mesh size 5 with any moderate performed as many as 3 times repeats so retrieved 9 units of the experiment. observation and measurement of the result is done by way of analysis in accordance with the parameters include capacity of machine and water content and cupping test by the expert panelists in their jobs. the result obtained will then be analyzed. results of the study showed that treatment difference fineness of the coffee produced grinder machine type conical burr mill give a real influence on the capacity of machine, the percentage losses and water content. reviewed performance aspects of machines known treatment on the level of fineness 5 mesh is the best treatment on machine with conical engine testing showed the value of 20.3203 kg/h on the test engine performance, 9.1668% yield ground coffee, water content at 1.9706% ground coffee. whereasin terms of the quality of the coffee is known to the treatment on the level of fineness 10 mesh is the best treatment on cupping test with a score of 83.25 keywords :coffee, grinder machine, conical burr
