Abstract

An image is one of the important assets for an organization that should be continuously built and maintained. A good image is one of the important tools, not only to attract consumers in choosing products or services, but also to improve customer satisfaction attitudes towards the organization. The image also shows the existence of an organization in the public eye, namely, showing the public's view of the organization that has formed over a long period of time. A well-formed image will also have a good impact on achieving the goals set by individuals or organizations. Based on preliminary research, it is known that the Image of PGRI Schools in Bogor Regency is relatively suboptimal. Therefore, research is needed to obtain information on variables related to improving Service Quality. The purpose of this study is to implement strategies and methods to improve organizational image by conducting research on the influence of personality variables, visionary leadership, organizational culture, and service quality. This study uses the path analysis method to determine the influence between the variables studied and the SITOREM method for indicator analysis to obtain optimal solutions in efforts to improve organizational image.

Abstract

Clean-water demand in coastal settlements has increased dependence on groundwater and may intensify water-quality deterioration caused by seawater influence, surface runoff, and local hydrogeological conditions. This study evaluates dug-well water quality in the South Depok Coastal area using Total Dissolved Solids (TDS) and turbidity, and examines the relevance of a hybrid multistage reverse osmosis (RO) system for raw-water treatment. Water samples were purposively collected from 10 community wells in January and May 2025. The mean TDS increased from 84.15 mg/L to 171.70 mg/L, while mean turbidity increased from 1.48 NTU to 5.81 NTU. The Pearson correlation between TDS and turbidity was positive, with r=0.74 in January, r=0.60 in May, and r=0.67 for the combined dataset. These results show that higher dissolved-solid concentrations tend to coincide with higher turbidity, although the relationship is affected by well-specific conditions, rainfall, suspended matter, and local hydrogeology. Although all TDS values remained below 500 mg/L, five May samples exceeded the 5 NTU turbidity threshold. A multistage treatment train consisting of sedimentation, multimedia filtration, cartridge filtration, pH-antiscalant conditioning, RO membrane separation, remineralization, and disinfection is therefore recommended to reduce particulate loading and stabilize treated-water quality. Future studies should report stage-by-stage permeate and concentrate data to validate membrane performance quantitatively.
