Abstract

Water consumption is very high in industrial pulp and paper. In addition, water also ranked at third for the world wide used. Low COD ratio (0.3) and biodegradability around 0.5 in wasted is considered ideal. One of the alternative way which is Advanced Oxidation Process (AOP) able to degrade harmful organism who less active in the normal degradation process. Active radicals in AOP act produced as oxidizing agents to mineralize complex chemical substances in waste. One of the active radicals, which is sulfate radical (SO42-) has a high oxidation potential of 2.5 to 3.1 V. Several studies showed that radical sulfates can be produced by catalytic oxidation process, such as combination of Peroxymonosulfate with homogeneous metal ion catalyst (Fe2+, Mn2+, Ni2+, Co2+, Cd2+, Cu2+, Ag+1, Cr3+, Zn2+). In this study, AOP method Peroxymonosulfate which was activated with the catalyst α-Mn2O3@α-MnO2-500 were used to treat COD content in organic waste water from pulp and paper industry. The α-Mn2O3@α-MnO2-500 catalyst was produced from 1:3 molar potassium permanganate and maleic acid that calcined at 500 ºC. These catalysis were characterized by XRD, BET and FESEM. From the XRD analysis obtained a combined peak between α-MnO2 and α-Mn2O3 are comparable with JCPDS standard. From the FESEM analysis, the crystal size of the nanorod obtained is around 18-60 nm in width and 47-185 nm in length. In BET analysis, the surface area is 3.765 m2/g. The degradation of COD content, appear in 50ºC, at retention time of 240 minute, with concentrations of 0.4 g/L catalyst dose and 1.6 g/L Peroxymonosulfate (67,52%).Key word: AOP, COD, Peroxymonosulfate, Waste water, Catalyst

Abstract

Foam glass is a material can be used as a insulation acoustic. The objective of this research is to investigate the effect of sintering temperature and time sintering on the physicalproperties of foam glass preparation from sheet glass and fly ash using dolomite as foaming agents. Slurry was made with mixed fly ash 50wt% and powder glass 50wt% incorporated indolomite 8wt% and strirred for 30 minutes; 300 rpm. Slurry was dried in oven at oven 105˚C for for 12 hours. Green bodies removed from mold and then it was sintered in the range 750, 900 and 950 oC at the furnace for 10,20,30 minutes. The effect of sintering temperature andsintering time on the shrinkage, porosity, density, compressive strength, microstructure and crystalline phases (XRD) were investigated. As the sintering temperature range 750oCthe density, compressive strength, shrinkage increased while the percentage of porosity decreased however as sintering temperature 900-950oC density and compressive strengthdecreased but percentage porosity increased. Furthermore, the sintering time increased the bulk density, compressive strength, shrinkage increased while the percentage of porositydecreased. The shrinkage, percentage of porosity, density, and compressive strength of the produced foam glass for insulation were 9,28-20,36%; 63-66%; 0,85-0,91 g/cm3; 1,53-1,69MPa; respectively. The optimum processing for producing foam glass for insulation was to use sintering temperature 900oC, time sintering 30 minutes.Keywords: foam glass; foaming agent; morphology; sintering

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 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

Abstract

Oil palm stem is solid waste in oil palm plantation.Oil palm stem content high cellulose which not much in use with optimal. Oil palm stem have potential for filler in wood plastic composite (WPC). The aim of the research is to study the effect of content of oil palm stem particle (SBS) and content of minarex on the morphology and properties of WPC based on a mixture of oil palm stem particle (SBS) and polypropilene (PP). Ratio used of SBS/PP is 70/30, 60/40 and 50/50 with sizes of the SBS is 60-100 mesh. As plastisizer was use minarex-H with values of 0%, 2% and 10% mash. As compatibilizer was use maleated anhydrid polypropilene (MAPP) of 5% mass. WPC samples were prepared using Rheomix 3000 HAAKE mixer at temperature of 170oc. Rotor speed of 60 rpm and time of 20 minutes. Physical testing of WPC focused in water content, bulk density, water absorption and thickness swell and mechanical testing of WPC focused in tensile strength, flexural strength. Beside that morphology testing of WPC using scanning electron microscope (SEM). The result showed ratio of SBS/PP and high content of minarex in WPC will degradate of properties of WPC. The best mechanical properties of WPC are on SBS/PP mass of 50/50 for tensile strength, 61,57 kg/cm2 and SBS/PP mass of 60/40 for flexural strength, 2,68 kg/cm2. key Words : Maleated Anhydrid PolyPropylene, Morphology, plastisizer minarex, Polypropylene, Oil Palm Stem.
