ASSESSMENT OF THE OPERATOR'S ABILITY TO PRODUCE QUALITY DRINKING WATER
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
Refill drinking water depot (DAMIU) is a business that aims to middle and lower class because of its affordable price. The laboratory analysis of refill drinking water quality showed that the total coliform had exceeded the threshold based on the Ministry of Health Regulation No. 492/2010. Direct observation in the depots resulted in a general conclusion that poor water quality was produced due to incapability the operators in operating water treatment units. The capability of DAMIU operator was divided into 3 latent variables, which are knowledge, attitude, and behavior. Those variables observed by 17 indicator variables described operator’s understanding about refill drinking water regulations (knowledge), depots operation and maintenance (behavior), and operator’s willingness to improve their depots performance (attitude). Structural Equation Modeling conducted through validity test and correlation test. Validity test result showed only 9 indicators were valid. Correlation test carried with the valid indicators identified that correlation value of knowledge, behavior, and attitude towards coliform contamination were 0,165; 0,151; and 0,374; respectively. The priority of the improvement was determined by fishbone analysis which made based on the valid indicators and adjusted by the correlation value between latent variables from correlation test. The first problem to overcome was operator’s attitude, followed by their knowledge, and last was their behavior.
