ABSTRACTThe quality of cut flowers can be improved by soaking them in a preservative solution, containing three basic compounds, sucrose, citric acid, and Lysol (called the basic formula). A research was conducted to find out an exact formulation which can give an optimal result by mixing the basic formula with cytocinine as a growth substances or anti-ethylene molecule as an completing agent (called the complete basic formula) for chrysanthemum cut flower. This research was done in the plant physiology laboratorium at Faculty of Agriculture of Bandung Raya University, Bandung on July to August 2004 by using univariat Randomized Block Design method consists five treatments, which are basic formula, basic formula + cynetine, basic formula + BAP, basic formula + AOA, and basic formula + STS. The result shows that the quality of chrysanthemum cut flowers can be kept by soaking it in a basic formulation preservative solution only, which containts 48 x 103 mgL-1 sucrose + 241 mgL-1 citric acid + 800 mgL-1 lysol in 14 hours. Soaking the cut flowers in a preservative solution, the decreasing of fresh weight is also minimalized and relative 2-days water uptake is maximalized. The number of ethylene that synthesized and respiration activity of chrysanthemum cut flowers can be pushed by adding the cytocinine into basic formula. Key Words: Preservative Solution, Quality Of Chrysanthemum Flowers, Growth Substances Cytocinine, Anti-Ethylene

ABSTRACTPalm juice as a raw material of brown sugar can be fermented easly. Smoke is used traditionally as an alternative indirect way to preserve the palm juice. Preservation of palm juice using liquid smoke directly have never been conducted before. The aim of this study is to investigate the effects of liquid smoke on palm juice preservation. First step, the liquid smoke was redestilated. Then, 0,50%, 1,00%, 1,50%, 2,00%, and 3,00%(v/v) concentration of liquid smoke was applied on palm juice when tapping and storage. It showed that the liquid smoke with concentration under 0,5% (v/v) cannot preserve the palm juice during 12 hours storage. 1% until 3% liquid smoke can preserve the palm juice during 12 hours storage. In fact, the pH of palm juice with liquid smoke increased when it was tapped, but the pH of palm juice without liquid smoke decreased certainly. The concentration of liquid smoke 1% and 3% could preserve the pH of palm juice above 6. That indicated the palm juice could be processed become brown sugar.Key Words: Liquid Smoke Palm Juice, Tapping, and Storage
