Abstract

Citronella oil is a non-timber forest product (NTFP) and is commercially obtained from the distillation of citronella leaves (Cymbopogon nardus L). Fragrant citronella leaves are one of the raw materials for obtaining vegetable oils in the form of essential oils. Essential oil is the main component consisting of composition in the form of geraniol and citronellal. The process of extracting essential oils can be done using various methods, one of which is the Vacuum Hydrodistillation method. The Vacuum Hydrodistillation method is carried out using a vacuum pump as a pressure guard and the boiling point of the distillation process does not exceed the boiling point temperature of water, which is 1000 C, so that the oil produced is maintained its purity. The vacuum hydrodistillation process of citronella was carried out for 3, 5, and 7 hours with each treatment using random and whole pieces of raw material. The resulting essential oil products were analyzed in the form of yield, density, refractive index and oil composition analysis using GC-MS. The best essential oil yields from citronella were obtained under operating conditions with random samples and distillation time of 5 hours. Where the yield produced is 0.17% with a refractive index of 1.41570 and a density of 0.92735 gr/ml. Keywords: Essential Oil, Vacuum Hydrodistillation, Fragrant Lemongrass, Geraniol

Abstract

Styrofoam is one type of food packaging that we often find. Styrofoam has excellent heat and cold resistance so it is used as an insulator. The ability to withstand good temperatures, lightweight and practical encourages the use of styrofoam as a food and beverage packaging material. However, Styrofoam contains many harmful substances and is not environmentally friendly. One solution is to replace the material for making styrofoam which is environmentally friendly called biodegradable foam. Sugarcane bagasse fiber has the potential as a basic material for making biodegradable foam. The purpose of this experiment is to determine the effect of the addition of bagasse fiber on the characteristics of biodegradable foam. This experiment uses a complete randomized design method with sugarcane bagasse fiber concentration treatment. The characteristic tests carried out include tensile strength test, water absorption test, biodegradation test, and thermogravimetric analysis. From the results of bagasse fiber decomposed 9,130 mg and still remaining 1,13 mg. The optimum concentration of biodegradable foam bagasse fiber on water absorption, biodegradation rate, and tensile strength in the 90:10 composition sample. The results of functional group analysis showed O-H and C-O groups which indicated that biodegradable foam is easily degraded by microorganisms in the soil. Keywords: Biodegradable foam, bagasse, cassava starch, packaging.
