| dc.description.abstract | Banana is a climacteric fruit that continues to ripen after harvest, resulting
in a relatively short shelf life. This study aimed to evaluate the postharvest maturity
criteria of Uli banana at different harvest ages and to determine the best harvest
time for postharvest handling. The experiment was conducted at Sukamantri
Experimental Field using four harvest ages of Uli banana, namely 75, 80, 85, and
90 days after anthesis (DAA). Postharvest observations were carried out at the
Postharvest Laboratory, Department of Agronomy and Horticulture, Faculty of
Agriculture, IPB University. The results showed that Uli bananas harvested at older
ages had a shorter shelf life and higher respiration rate than those harvested at
younger ages. Fruit harvested at 75 DAA had the longest shelf life, reaching 15
days, while fruit harvested at 90 DAA had the shortest shelf life, reaching 11 days.
Heat unit accumulation increased with harvest age, ranging from 909 to 1077 °C
days. Harvest age showed differences in respiration rate, weight loss, edible part,
total soluble solids (TSS), and total titratable acidity (TTA), while fruit softness and
vitamin C content were relatively similar. Based on physical, physiological, and
chemical fruit quality, the harvest age of 85 DAA with heat unit accumulation of
approximately 1018 °C days produced the most optimal postharvest quality of Uli
banana. | |
