Sugar cane is a sugar-producing plant. Sugar needs in Indonesia have not been able to meet the needs of the community due to the low yield. The decrease in yield is due to delayed processing and incorrect harvest time. This study aims to determine the age of sugarcane and the delay in the process of reducing yield. The research was arranged in a factorial completely randomized design (CRD) with three replications. The first factor is the process delay time which consists of 0, 12, 24, and 36 hours. The second factor is the age of sugarcane which consists of ages 10, 12, and 14 months. The results showed that delay in processing sugar cane affects briks (%), pol (%), reducing sugar levels, and partial loss of sugar. Age of sugarcane affect briks (%), pol (%), reduce the sugar content, and loss of sugar crystals. The decrease in yield was due to delays in processing and by the age of the plant. The decrease in yield due to processing delays during the 12, 24, and 36 hours delays was 7.20, 6.71, 6.23, and 5.93% compared to direct processing. The decrease in yield due to plant age shows that there is a significant difference. The highest yield was produced by plant age 12, 10, and 14 months with a yield of 7.18, 6.58, and 5.80%. Processing delay causes a decrease in yield, and the age of 12 months is the right time to harvest sugar cane. In the future, it is expected that the yield can be maximum, so there is no delay in processing for too long and the exact age of the plant is 12 months.
