The purpose of this study was to determine the influence of microwave electromagnetic waves on the bio briquette quality of pecan shells through power variants and the duration of carbonization time. The stages are pecan shell cleaning, carbonization process with microwave electromagnetic waves at predetermined power and duration of time (0.5, 1, 1.5 and, 2 hours), the process of crushing into charcoal with disk mill equipment, mixing with adhesive material with a ratio between the mass of charcoal and adhesive material 80:20 (b/b), bio briquette printing and the last stage is drying with sunlight for 2 days. From the analysis obtained the most optimum results are at 440 watts of power for 1 hour with the following results: water content of 7.30%, ash content: 7.48%, Carbon Bound obtained: 73.31%, Volatile matter: 30.23% and, the calorific value of bio briquette is: 5706.24816 cal/gram</span></p><p><span lang="EN-US"><br /></span></p><p><strong>Keywords:</strong> bio briquette, pecan shell, electromagnetic wave, carbonization, microwave</p><p><span lang="EN-US"><br /></span></p>
