Publisher : Balai Riset dan Standardisasi Industri Pontianak

Orange (Citrus nobilis var. microcarpa) is the main commodities in Pontianak. Production of essential oils from orange peel wastes and its use for soap aromatherapy substance could improve its economic value. This study is aimed to produce the essential oils from orange peel wastes with the highest limonene content by distillation. Its application for aromatherapy soap substance also evaluated. Distillation of essential oils from orange peels was performed at 1000C and 1100C for 4, 5, 6 and 7 hours. The results showed that at 1000C for 7 hours produced the highest limonene content, reach 97.69%. The essential oils color was pale yellow, specific gravity 0.84, refractive index 1.47, solubility in 90% ethanol 1:1 (transparent), acid value 0.143% and ester number 5.37. The aromatherapy soap produced with addition of 3.6% of limonene oils is in accordance with SNI 06-3532-1994 except for water content parameter.

The main componenet of lemongrass oil that is sitronellal and rhodinol (sitronellol and geraniol) was isolated by using vacuum of distillation fraksinasi. Variably the research included the variable continue to, that is the sample weight (300 mL) and process time (4 hours); and the variable changed, that is the pressure (80, 95 and 100 mbar) and the temperature (145, 150, and 160o C). Results of the analysis of the ras material showed that lemongrass oil that came from Kota Panjang, Gayo Lues, Province Aceh had the content sitronellal that was high that is of 51.067% and rhodinol of 30.761%. The characteristics from lemongrass oil was yellow faded, the ray index 1.466, the specific gravity 0.889 solubility in alcohol 1:1 clear and the round of optics 19.15. The distillation sitronellal, 28.87% rhodinol (22.60% geraniol and 6.27% sitronellol) and 11% other component. The condition for the process that was good enough in the isolation sitronellol used distillation vacuum of fraksinasi with the temperature and the pressure that were low that is 145o C and 80 mbar. The condition for the process that was quite good in the isolation rhodinol was use to use vacuum of distillation fraksinasi in the temperature and the pressure that were not too high and or low that is 150o C and 95 mbar.

Utilization of Durian Skin as Raw Materials of Art Paper Sukma Budi Ariyani; Hidayati Hidayati

This research was to utilize solid waste of durian (durian skin) into economically valuable products. The purpose of this research was to obtain a decorative paper or art paper which can be used as a wide range of creative products such as photo frames, tissue boxes, pencil boxes and others. The research was carried out by destroying the skin of durian and other materials to form slurry and then molded and dried. Assessment of art paper quality was based on the beauty of its performance because it was display the fibers on the surface of the paper. It has been carried out analysis of gramatur, tear resistance, moisture content and ash content of the paper produced by durian skin. Paper with gramatur value, moisture content, low ash content and high tear resistance was the good quality paper. For gramatur and water content testing, a paper which was given a red ocher dye (D) is a paper that has the lowest value of gramatur and water content, each of 0.0212 g/cm2 and 7.77%. While the ash content and tear resistance testing, colored paper with mangosteen peel 17% (E) has a low ash content (0.056%) and high tear resistance (104 times fold).
