Asparagus is a vegetable that is very vulnerable to get physical damage after being harvested. To maintain the quality of freshness of asparagus during storage, proper packaging and storage is needed. This research aims to analyze and determine the best amount of perforation in the packaging of asparagus using 0.03mm polypropylene plastic thickness. First of all, Asparagus would be packaged in polypropylene plastic. Next step, the plastics would be perforated by 2, 4, 6, 8, 10 holes, and one specimen plastic would be left with no holes at all. This step was repeated 3 times. Afterward, these samples would be stored in refrigerator with a temperature of 6±2oC. The results showed that perforated polypropylene plastic with 2 holes is the best packaging because this type of polypropylene plastic was able to maintain weight 41.3%, texture 25.3668 N, color (L 50.91, a 4.52, b 33.10), freshness 4 (fresh), and total dissolved solids 9.4 °Brix of asparagus during storage.
