Abstract

Membrane technology is growing rapidlybecause of its superiority and has beenwidely applied in various industries. Thewaste of teak sawdust is increasing as thefurniture industry develops, but its utilizationis not optimal. The purpose of this study wasto determine the effect of the addition of TiO2on the mechanical properties andperformance of photocalytic membranesfrom cellulose diacetate teak sawdust forprocessing PDAM water raw materials.Cellulose isolation from teak sawdust wascarried out by adding NaOH 17.5% (b / v)and continued with cellulose bleachingprocess. Cellulose teak sawdust wassynthesized into cellulose diacetate byacetylation method. Membrane production isdone by phase inversion method withvariations in the composition of TiO2 0.25%,0.5%, 0.75% and 1% and also variations inevaporation time 20 seconds, 25 seconds,30 seconds and 35 seconds. The photocyticmembrane of cellulose diacetate from teaksawdust and TiO2 produced wascharacterized by thickness test, mechanicalproperties and performance. Photocalyticmembranes with optimum conditions arecharacterized by SEM (Scanning ElectronMicroscopy), FT-IR (Fourier TransformInfraRed) and antibacterial effectiveness.The optimum composition of thephotocatalytic membrane is 16% cellulosediacetate, 4% formamide, acetone 79% and1% TiO2 with 30 seconds evaporation time.The mechanical properties obtained werestress 1562,50000 kN / m2, strains 0.01 m /m and Young Modulus 141593,4835 kN /m2. The membrane has an averagethickness of 0.04 mm, a flux value of 683.10L.m2.hari-1, a rejection value of 97.74% andan antibacterial effectiveness of 99.57%.

Abstract

Widal examination is an agglutination examination using suspension of Salmoella typhi and S. Paratyphi as antigens to detect the presence of antibodies against Salmoella typhi or S. Paratyphi in patient's serum. Salmonella infections in humans can vary in the form of infections that can heal itself (gastroenteritis), but can also be a serious case if there is a systemic spread (enteric fever). The purpose of this study was to determine the effect of delaying the slide method widal examination in typhoid fever patients at Anna Medika Madura General Hospital. This research uses a quasi-experimental method (pre-experiment / quasi experimental design). The variable of this study is the effect of the delay of the Widal Slide Method examination. The population was 25 patients at Anna Medika Madura Public Hospital, while the sample was 25 respondents. The sampling technique used was purposive sampling. The analysis technique used in this study was the Repeated Anova Measure test. The statistical test results of this study were obtained the level of confidence α = 5% (0.05) with P value> α 0.05 ie P Value = 0.354 then H0 received H1 was rejected, so it can be concluded that there was no effect of delaying the widal slide examination method in typhoid fever patients at Anna Medika Madura Public Hospital. Based on the results of the study, it is expected for further researchers to try to conduct widal examination using plasma without being separated from the tube with temperatures above 25 ° C
