Abstract

The preparation of polyelectrolyte complex (PEC) as supporting material of urease immobilisation for  Hg(II) biosensor has done. PEC membrane can be prepared by mixing hydrosol alginate and chitosan hydrosol with 1: 1 ratio at pH of 5.28 approximately. The optimum conditions and characteristics of biosensor was determined. The formed alginate–chitosan PEC membrane was confirmed by using FTIR spectroscopy and SEM analysis. The results shoed that PEC of alginate-chitosan was formed and the proposed biosensor is an excellent platform for sensitive detection of Hg (II).

Abstract

Indonesia’s target to be a new industrial country makes a wide chance in the developing of many industrial sectors. The main problem is the disruption of environmental balance due to poorly managed liquid waste released by the industry. Heavy metal such as chromium (Cr) is the typical pollutant generated from tannery industry in Indonesia. Toxicity test of desorbed chromium ions from polluted soil around tannery industry in Yogyakarta-Indonesia by using Brassica junceaand Helianthus annuus L.has been carried out. In this research, soil samples were dividedinto four sample points based on the distances from the waste water point sources. Metal content and some physico-chemical properties including ash content, total organic carbon, and cation exchange capacity were determined in this study. Furthermore, the chromium ions adsorption and desorption from polluted soils were investigated and measured by atomic adsorption spectrophotometry (AAS). Thus, ecotoxicity testsof soil eluates from desorption experiments wereperformed with Brassica junceaand Helianthus annuus L.The resultsshowed that sample III had the highestCr content at916mgkg–1.The adsorption isotherm of Cr ions into soils followed Langmuir isotherm with the highest maximum adsorption capacity value at 14.286 mg kg-1in the sample point IV (unpolluted soil). The optimum desorption of chromium occurred at pH 3. Toxicity test showed that Cr ions had toxic effect to Brassica junceaand Helianthus annuus L.

Abstract

AbstractThe variables used in this study are personal factors, organizational factors, and non-organizational factors. The research objective is to describe the Organizational Commitment which includes Personal Factors, Organizational Factors and Non-Organizational Factors at Grab Drivers in Lowokwaru District Malang, to identify and analyze the significant influence of Personal Factors, Organizational Factors and Non-Organizational Factors simultaneously or partially on Organizational Commitment. driver Grabin Lowokwaru Malang District. The population in this study is thecommunity driver restoin the District of Lowokwaru Malang, amounting to 90 drivers. The sample in this study amounted to 90 respondents. The sampling technique used in this research is saturated sampling technique. The data analysis method used is the Instrument Test, Multiple Linear Analysis, Hypothesis Test and Coefficient of Determination. From the results of the description analysis, it is concluded that in general the respondents agree with Personal Factors, Organizational Factors and Non-Organizational Factors also have a high enough Organizational Commitment, but in this study Non-Organizational Factors have no significant effect on Organizational Commitment. Based on the results of the Multiple Linear Regression Analysis, it can be seen that the Sig. from non-organizational factors of 0.818> 0.05. In the t test, it was concluded that personal factors, organizational factors and non-organizational factors simultaneously affected Organizational Commitment with the Sig. equal to 0.00 <0.05. This is evidenced by the coefficient of determination of the adjusted R Square value of 161, which means that the dependent variable has a contribution of 16.1% to the independent variable. As for partially but not significant effect on Non-Organizational Factors on Organizational Commitment as evidenced by each Beta coefficient on the t test for Personal Factors (0.325), Organizational Factors (0.252), Non-Organizational Factors (0.025) have no significant effect on Organizational Commitment. on the driver Grab in Lowokwaru Malang District.  Keywords: Personal Factors, Organizational Factors, Non-Organizational Factors and Organizational Commitment.
