Abstract

The waste of timber industry can be utilized to producesome valuable products. A research had been conducted tostudy such possibility. The research was to study the conversionof wood into charcoal briquetting using adhesive or heatingprocess. Result showed that the heating value of charcoalbriquetting made from kempas wood (koompassia malaccensismaing), meranti (shorea spp.) and pulai (alstonia spp)increases significantly compared to that of raw material. Theproduct made from kempas wood (koompassia malaccensismaing.) was formed to have the highest energy per cc (density)followed by those of made of meranti (shorea spp.), ramin(gonystylus bancanus kurz.). However, raw materialavailability must be consideret in establishing charcoalbriquetting industry.

Abstract

Research has been carried out using x-ray diffraction analysis and analysisof Atomic Energy Dispersive X-Ray (EDAX) on a sample of oil palm shellcarbon. X-ray diffraction spectrum of a sample of oil palm shell carbon has anamorphous structure with two peaks in the energy intensity of 639 AU and 232AU (Arbitari Unit). The elements contained in the oil palm shell carboncontaining elements other than carbon C amounted to 98.48% of other elementsthat are also contained 0.71% Si silicon. EDAX analysis of the percentageobtained on the building blocks of atomic carbon C is approximately 99.69% and0.31% Si silicon. SEM analysis obtained by cross-sectional shape is irregular, soit can be concluded that oil palm shell carbon is amorphous, and visible changesin the peak position, width and height of the temperature difference diffractogramto the formation of massive carbon charcoal granules.

Abstract

Production of castor oil biodiesel has been done by transesterification process. The castor oil was previously tested for titration and produced 77,78 % free fatty acid. The process was done in a autoclave by mixing the materials of castor oil to methanol in 1:12 mole. The reaction use 4 % and 8 % of PSS catalyst in 1200C for 6 hours. The solution was neutralized by ammoniac and estracted by n-hexane. The transesterification resulted in 2 layers: upper layer containing methyl ester (FAME) and the lower layer containing residual glycerol and methanol and than separated. The upper layer of the separating funnel contained FAME added sufficiently by n-hexane, and then washed by aqueous repeatedly. The filtrate was distillated by an usual distillation and than vacuumed and the residueweighted. FAME has finished then tested with Gaskromatografi(GC) to determine the content of the results of the reaction, thebreakdown of methyl ester= 93.35%, monogiserida= 0.348%,diglycerides= 0.448% and triglisrida= 0.685%.

Abstract

The varistor ZnO has been made by using raw materials: ZnO(E-Merck) and additive 0 %, 2.5 %, 5%, 7.5%, and 10% wt.Bi2O3. The important property of varistor ZnO is coefficient ofnon linier () and it can give influence correlation betweencurrent I and voltage V. The mixing process of raw materialswas done by using magnetic stirrer and liquid acetone asmedia, and then was dried at 60oC, and also grinded untilpassing 400 meshes. Pellet was made by using pressing 50MPa, and fired at 1050oC with holding time 2 hours. Afterfiring, all samples are characterized, such as: measurement ofcoefficient of non linier (), and observation of microstructureby using Scanning Electron Microscope (SEM). The resultsshow that sample without additive has  less than 5 and thissample has not properties as varistor, but the highest value of is 64 for sample with additive 7.5% Bi2O3. The result ofphotos SEM shows that the increase of percentage of additiveBi2O3 can influence of formation grain boundary and grainsize. Where, value of coefficient of non linier () is depend onexisting of grain boundary and thickness of grain boundary.

Abstract

Negative binomial regression model is used to overcome theoverdispersion in Poisson regression model. This model can be used to model therelationship of the infant mortality and the factors incidence. Geographicalconditions, socio cultural and economic differ one of location another locationcauses the factors that influence infant mortality is different locally.Geographically Weighted Negative Binomial Regression (GWNBR) is one ofmethods for modeling that count data have spatial heterogeneity andoverdispersion. The basic idea of this model considers of geography or locationas the weight in parameter estimation. The parameter estimator is obtained fromIteratively Newton Raphson method. This research will determine the factors thatinfluence infant mortality. GWNBR model with a weighting adaptive bi-squarekernel function classifies regency/city in East Java into 16 groups based on thefactors that significantly influence the number of infant mortality. This model isbetter used to analyze the number of infant mortality in East Java in 2008 due toa smallest deviance value.
