Abstract
Coffee is one of the superior plants in North Sumatera Province, where the types of coffee cultivated are arabica coffee (Coffea arabica), robusta coffee (Coffea canephora) and liberica coffee (Coffea liberica). Coffee pulp is one of the solid wastes from coffee industry that can still be utilized because of its nutritional content. This study aims to determine the characterization of three types of fresh coffee pulp and to determine the characterization of cascara after being processed into cascara powder and cascara extract. Based on the research results, Liberica coffee has a larger size and density than Arabica and Robusta coffee.
