      "abstract": "Proses roasting merupakan tahapan penting dalam pengolahan kopi karena\r\nberpengaruh terhadap kualitas aroma, rasa, dan warna biji kopi. Namun, sebagian\r\npelaku usaha masih menggunakan sistem roasting konvensional yang memiliki\r\nketerbatasan dalam efisiensi dan pengendalian suhu. Penelitian ini bertujuan untuk\r\nmerancang mesin roasting biji kopi berkapasitas 50 kg guna meningkatkan\r\nproduktivitas dan kualitas proses penyangraian pada skala usaha kecil dan\r\nmenengah. Metode yang digunakan meliputi observasi lapangan, studi literatur,\r\nperumusan masalah, desain dan perhitungan teknis, perakitan alat, serta pengujian\r\nkinerja. Mesin yang dirancang menggunakan motor listrik 1 HP dengan putaran\r\n1400 rpm, gearbox rasio 1:30, dan sistem pemanas berbahan bakar LPG. Hasil\r\nperancangan menunjukkan putaran drum roasting sebesar 33,33 rpm. Pengujian\r\nkinerja menunjukkan mesin mampu menyangrai 50 kg biji kopi dalam waktu 58\r\nmenit pada suhu stabil sekitar 225°C. Mesin yang dirancang mampu bekerja\r\nsecara efektif, menghasilkan proses penyangraian yang lebih merata, serta\r\nmendukung peningkatan kapasitas produksi UMKM kopi.",
