Abstract

Bambu Tali leaves are part of bamboo plants that have not been used optimally. Bambu Tali leaves can be used as a refreshing drink. The aims of this study is to determine the effect of blanching and drying temperature on the characteristics of the Bambu Tali leaves and to determine method of blanching and drying temperature which can produce the best characteristics of Bambu Tali tea leaves. This study used a Randomized Block Design with two factors. The first factor’s is the blanching method that is without blanching, steam blanching, and water blanching. The second factors that is drying temperature that consisting of 50oC, 60oC, and 70oC. Data were analyzed by analysis of variance and continued with Tukey test. The results showed that the blanching treatment and drying temperature significantly affected the water content, ash content, extract content in water, total phenolic, IC50, and organoleptic test. The steam blanching treatment with a drying temperature of 70oC is the best treatment to produce Tali’s bamboo tea leaves with a characteristics of water content is 5.17%, ash content is 5.52%, extract content in water is 35.70%, total phenolic is 36.92 mg GAE/g, and antioxidant activity of IC50 2,629.06 ppm, and color scoring of sensory evaluation is 3.55 (yellowish green to green), taste scoring is 3.55 (slightly astringent to astringent), Scent scoring of 3.45 (slightly leaf scent to leaf scent), and overall reception 4.90 (rather like). Keywords: Gigantochloa apus Kurz., blanching, drying temperature, tea.

Abstract

Used cooking oil is cooking oil that has been used over and over again. Used cooking oil can be used as raw material for soap and biodiesel. However, before being used, the used cooking oil must be purified using an adsorbent. This study aims to determine the effect temperature and stirring time on the characteristics of used cooking oil purified with bagasse and determine the best temperature and stirring time to produce the best characteristics of used cooking oil. This study used a factorial randomized block design. The first factor was the adsorption temperature which consists of 70 °C, 80 °C, 90 °C, and 100 °C. The second factor was the stirring time which consists of 3 levels, namely: 60, 70, and 80 minutes. The data were analyzed by analysis of variance and continued with the Tukey test. The results showed that the adsorption temperature and stirring time significantly affected the clarity, water content, free fatty acid content, and brightness level. The interaction between treatments had a very significant effect on the level of clarity and brightness. The best treatment of the used cooking oil refining process using bagasse is the treatment at 100°C temperature and 80 minutes stirring time, with the characteristics of a clarity level of 0.149±0.010 A, 0.13±0.02% water content, 0.21±free fatty acid content. 0.02% and a brightness level of 47.37±0.01L*.
