Abstract

The aim of this study was to determine the content of phenol in the liquid smoke palm kernel shells produced at a temperature 600ᵒC, 700ᵒC, 800ᵒC. Pyrolysis process was carried out by using a furnice that surrounding covered with fire-resistant white cement so that the smoke does not escape into the air and liquid smoke produced more leverage. Temperatures used 600ᵒC, 700ᵒC, 800ᵒC use with condenser-type spiral coil number of turns 30. Liquid smoke produced in deposited for 7 days and in the centrifuge with a rotation speed of 3800 rpm for 60 minutes, filtered and distilled at 125ᵒC temperature for 60 minutes. Liquid smoke analyzed (characterization) using GC-MS and phenol identified for each temperature 600ᵒC is 35.09%, the temperature 700ᵒC is 37.962% and 37.494% temperature 800ᵒC is.Keywords: Liquid Smoke, Phenol compounds, GC-MS

Abstract

ABSTRACTPoly vinyl Chloride ( PVC) represent materials of thermoplastic as solid polymer conducted in the form of plastic sheet which not yet been mixed with something additive, while other film mixed with additive in the form of oleic acid and Palmitic Acid with comparison 10 : 1; 10 : 2; 10 : 3; and 10 : 4; tested migration testing by arranging in film and pressing between each of PVC and oleic acid, PVC and Palmitic Acid; after that they kept in a place that available and left araund 30 days, then the additive migration of oleic acid into PVC equal to 4.2035 % and the additive of Palmitic to PVC 5.8080 %. From the result obtained the amount of additive migration of oleic acid to is PVC smaller than the additive migration of Palmitic Acid to PVC. It also can be seen that effect of additive migration to solid polymer progressively increase (linearly compass with keeping time).Keyword : Polymer - PVC - Additive - Migration - Time.

Abstract

Asphalt emulsion is a mixture of asphalt (55% - 65%), water (35% - 45%) and emulsifier material (1% - 2%). This research studied the effect of adding surfactant tween 80 (polyoxyethylene sorbitan mono-oleate) on the viscosity and activation energy. The research data was obtained by mixing asphalt, surfactant tween 80, and water and then heated at a certain temperature and viscosity values were measured using a Brookfield Viscosimetre at 500 rpm. The results show that the viscosity and the activation energy increase with the addition of surfactant tween 80: η = -49,82380 cp end Ea = 9,18452154 kJ/mol
