Abstract
Penelitian ini bertujuan untuk merancang dan membangun mesin pengaduk adonan roti dan donat tipe horizontal dengan kapasitas 20 kg/jam sebagai solusi bagi industri rumah tangga dan usaha kecil menengah (UKM) yang membutuhkan proses produksi cepat, efisien, dan higienis. Metode penelitian menggunakan pendekatan Design Science Research melalui tahapan analisis kebutuhan, perancangan mekanis, pembuatan, perakitan, serta uji kinerja. Hasil pengujian menunjukkan bahwa mesin mampu mengolah 10 kg adonan dalam waktu 14 menit 49 detik dan 20 kg adonan dalam 29 menit 46 detik, dengan efisiensi waktu 67–70% dibandingkan metode manual. Analisis daya motor bensin 6,5 HP serta perhitungan kekuatan rangka ST 60 dan umur bearing menunjukkan bahwa mesin aman digunakan dan memiliki umur pakai hingga ±5 tahun. Dari sisi ekonomi, penggunaan mesin ini mampu mengurangi biaya tenaga kerja hingga 60% dan meningkatkan kapasitas produksi harian 2–3 kali lipat. Dengan demikian, mesin ini terbukti efektif dan layak diterapkan pada skala usaha kecil maupun menengah serta berpotensi dikembangkan lebih lanjut dengan sistem otomatisasi dan penggunaan energi ramah lingkungan
