Abstract

The use of natural rubber in the form of solids such as crumb rubber (SIR 20) will require a long time when mixing with asphalt, therefore mastication process is used before mixing with asphalt. Mastication is process of grinding natural rubber in open mill to break the chain in natural rubber polymer. The aim of this study to determine the effect of rubber mastication and rubber storage time after mastication on modified asphalt characteristics. In mastication process, asphalt as plasticizer agents with levels of 0%, 1%, 2%, 3%, 4% and 5% w/w and rubber storage time after mastication are 0 days and 30 days. The asphalt used is 60/70 penetration type asphalt. Asphalt modified by mixing SIR 20 and asphalt with a ration of 1:9 at temperature of 165oC and stirring time for 30 minutes. Modified asphalt is tested for penetration test, softening point, marshall stability, and weight loss. The results of the study showed that the addition of plasticizers in rubber and rubber storage time after mastication affected the value of penetration, softening point, marshall stability, and weight loss. The best results were obtained at 0% plasticizer content and 0 days rubber storage time with a Penetration value of 58.5 dmm, Softening Point 59.1ºC, Marshall Stability 1710.9 kg, and Weight Loss 0%. The storage time of 30 days, the best results on a 5% plasticizer content with a Penetration value of 58.4 mm, Softening Point 56.3ºC, Marshall Stability 1463.3 kg, and Weight Loss 0.27%.Keywords : asphalt modification, plasticizer, mastication, SIR 20, penetration, softening point, marshall stability

Abstract

Palm Fatty Acid Distillate (PFAD) is a byproduct from palm oil processing industry that used as raw material for synthesis polyester based vegetable oil. The purpose of the research is to study polymerization reaction of ester from PFAD using inisiator benzoyl peroxide 0,4%. There are three step reaction in this research that was esterification, polymerization, and polyesterification. The esterification stage was done at temperature 70oC, reaction time 2 hours, reactant ratio 1:8 (ALSD : metanol), and concentration catalyst H2SO4 1% (w/w) ALSD. Polymerization stage was done at variation of temperature 120, 130, and 140oC and variation reaction time 3, 4, and 5 hours using initiator benzoyl peroxide 0,4% (w/w) methyl ester. Polyesterification stage was done at temperature 175-200oC, reaction time 4 hours, and ratio reactant 1:1 (polymerized methyl ester : ethylene glikol). Product was analyzed by using FT-IR, GC-MS, and viscosity. The result of FT-IR showed that vinyl group was presence who indicated double bonding was presence and polymerization was not occur. The result of GC-MS showed there had no change of molecular weight. And product with temperature 130oC and reaction time 5 hours has higher viscosity value.Keyword : benzoyl peroxide, esterification, PFAD, polymerization

Abstract

Palm frond biomass is potentially to be used as a filler for plastic-wood composite products known as Wood Plastic Composite (WPC). This study aims to determine the influence of solvent type and temperature on preparation of palm frond as raw material of WPC. The palm frond which has been reduced to powder is dried in open air for ± 24 hours. Further drying uses an oven at 1050C where the final water content of the powder is 5%. Furthermore, the material is scaled down again in size to obtain 60 mesh. Palm oil powder is extracted for 15 minutes using solvent and high temperature. The solvent variations used are NaOH and H2O2 with concentration of 1 N while the variation temperature of extraction step is 100oC, 120oC and 140oC. The results showed that the type of solvent has a relatively significant effect on cellulose content of frond is increasing cellulose level of 13.44% - 22.23%, while the temperature changes did not give significant effect to the increase of fronds cellulose levels. The best preparation results were obtained in the preparation using NaOH solvent at 140 ° C with a cellulose content of 57,47%.Keywords: moisture content, palm frond, preparation, wood plastic composite
