The research conducted a completely randomized design (CRD). The results analysis of beta-carotenes content of fresh pumpkins of 0.82 mg/100 g after processed into yoghurt by storage time and lighting at the highest levels of beta-carotene by 0.071 mg/100 g on 2nd day in darkness packaging, while the lowest levels of beta-carotene of 0.050 mg/100 g on 4th in darkness packaging. The highest total acid found in pumpkins yogurt in light packaging on 10th day in the amount of 1.047%, whereas lowest total acid present in yoghurt pumpkins in darkness packaging on 2nd day is 0.981%. Lighting treatment and storage time had not significant on changes in the levels of beta-carotene and total acid. The level of preferences indicate that storage time the 6th day of the desirability of consistency, flavor, aroma, and color.
