Application of TiO2 for Self Cleaning in Water Based Paint with Polyethylene Glycol (PEG) as Dispersant
No full textTiO2 anatase and rutile having composition of 1%, 1.5%, and 2 % have been applied as a self-cleaning in water based paint containing dispersant polyethylene glycol (PEG) with molecular weight of 6000. Anatase TiO2 is used for self-cleaning and rutile TiO2 for ultraviolet protection. Mud and dye were used as pollutant for self cleaning test. Atomic Force Microscopy (AFM) was employed for evaluating TiO2distribution. Image J was used to calculate area of pollutant and distribution of TiO2. The results show that 2% TiO2 with ratio of anatase : rutile 90:10 has the minimum pollutant area indicating the best self cleaning properties. FTIR characterizations show absorbance peak at 1080 cm-1 wave numbers indicating characteristic peaks of PEG. The increase of peaks at around that wave number indicates maximum TiO2 aggregation. It was found that 2% TiO2 with ratio of anatase : rutile 90:10 has the minimum peak at that particular wave number. The AFM image for this composition shows that aggregate distribution of TiO2 in the film paints are more homogenous compare with other samples leading to an improved self cleaning properties
Identification of the Main Water Quality Parameters for Monitoring and Evaluating Watershed Health
No full textWater quality is one of the crucial parameters in monitoring and evaluating watersheds. A large number of parameters causes the monitoring and evaluation of watershed performance to be less efficient and costly. This study aims to determine the main parameters as a method of simplifying water quality observation parameters by producing equations that can be used to predict the level of pollution of a non-point source pollutant (watershed). A sampling of surface water was carried out by purposive sampling at several outlets located in the Brantas and Upper Solo watersheds. The research parameters analysed were: TSS, TDS, BOD, COD, Phenol, Free Chlorineine, Sulfide, Arsenic, Fe, Pb, Phosphate, Nitrate, Nitrite, Detergent, Turbidity and E. Coli. The results of the analysis of water quality are used to calculate the value of the Pollution Index (PI) according to the Decree of the Minister of Environment No. 115 of 2003 and to determine the class of water quality standards that refer to Class III water quality standards, in Government Regulation No.82 of 2001. The analysis showed that all samples were at mild to moderate pollution levels, and did not meet class III water quality standards. Multiple regression analysis produced two equations, namely: Model 1: PI = 3.952 + 91.668 Phenol and Model 2: PI = 3.086 + 80.167 Phenol + 0.152 BOD, with R squared values of 53% and 69.9% with a confidence level of 0.005. Thus the prediction of pollution levels of similar watershed can be made only by using the two most influential parameters namely phenol and/or BOD alone.

No full textThe research was carried out in order to determine the effect of paraquat on the early development of chick embryos. Doses of paraquat 0, 0.1, 0.25, 0.55, or 1.25 mg/egg paraquat were administered to the unincubated Highland chick embryos and examined for cardiovascular abnormalities on 96 hours of incubation. The result showed no malformation in heart, but aortic arch development occurred. Nevertheless, doses 0.55 and 1.25 mg/egg of paraquat caused a highly significant increase (p<0.01) in the extraembryonic vessels malformations. All the administered doses did not significantly caused intraembryonic vessels malformations. Doses 0.55 and 1.25 mg/egg of paraquat also caused a highly significant increase (p<0.01) in both frequency of erythrocytes abnormalities and the micronucleated erythrocytes. This experiment represented a significant increase in extraembryonic vessels malformations, abnormalities and mutation level of erythrocytes due to the administered doses.The research was carried out in order to determine the effect of paraquat on the early development of chick embryos.

Perbedaan Pemberian ASI Eksklusif Antara Ibu Rumah Tangga dengan Ibu yang Bekerja di Luar Rumah di BPS Umu Hani Bantul Tahun 2011
No full textBased on World Health Organization (WHO), The cause of 54% mortality baby in the world is infl uenced by nitrition factors including affected by granting breast-feeding. Tendency of the use breast feeding in some society is declining. This is due to paradigm shifting in any women because of growing understanding women about self-actualisazion. This research aims to compare providion of exclusive breastfeeding between working mothers and household mothers at BPS Umu Hani Bantul. This observational study used cross-sectional design with consecutive sampling. Data were obtained by using questionnaire and analysed through table a frequency distribution subjects and data statistic was tested by using chi-square. The result were 84% breastfeeding mothers at BPS Umu Hani as housewife, 15.9% of those working outside and at about 68,2% given exclusive breastfeeding. There was significantly distinctive at about p< 0,05 on the proportion of exclusive breast-feeding given by household mothers and housewife mothers.</p
