<strong>Abstract. </strong>Intensive water quality determination needs to be adjusted with technological developments to meet today's society's needs and increased water pollution due to urbanization. Therefore, early detection is essential for in site water quality determination and as a critical consideration in making health and environmental decisions. OpenCV is a library programming feature for Computer Vision which focuses on extracting information from images in real-time, this can be considered to be potential to measure the pollutant concentration. <strong>Objectives:</strong> This study identify the potential of colorimetry analysis method by using OpenCV as an alternative method for pollutant concentration measurement<strong>. Method and results:</strong> First stage, this study collecting the data of NH3 phenate and Pt-Co CU from the spectrophotometer. The first stage also was including the development of an OpenCV code. Then, the data was collected were processed to get the concentration of NH3 and Pt-Co both using OpenCV and spectrophotometer; factors that influence the Pt-Co sample image measurement process by using OpenCV-Python was analyzed too. Then in the analysis stage, the result of the two measurement method was tested by statistic determine its significant difference. The conclusion found whether OpenCV could be potential to measure the pollutant concentration or not. <strong>Conclusion:</strong> the OpenCV has potential to be use as alternative colorimetry measurement method to determine water pollutant as there is no significant difference in the spectrophotometric method results and the results from OpenCV for Pt-Co sample.  Meanwhile, in this study found that the result of NH3 from spectrophotometer is nonlinear different with from OpenCV that is linear. Thus, further research is needed to test the validity of OpenCV method.  The factor influence of measurement using OpenCV code is when determining the Region of Interest (ROI) and determining the pixel values for the normalized box filter

Higher education institutions has a huge population that induces the large consumption of drinking water, the large consumption of electricity, the production of large quantities of garbage, the use of high transport and the rise in the building of facilities. Thus the implementation of Environmental Management System in Unversity Campus is crucial to achieve sustainability campus. This study is a literature review about the implementation of the ISO 14001 Environmental Management System in University campus and its recommendation. The discussion also discussed its implementation in indonesia’s campus as well as in other country campus. The implementation have to be done is start from environmental policy that made by campus adjusting to the ISO 14001 , the environmental management planning , implementation , and assessment for evaluation. Several campus has been implementing environmental management system but still need improvement. Universities should start implementing environmental management practices that promotes sustainable development and protection of the environment. These initiatives can focus on various environmental aspects, depending on the needs and culture of the campus. Although some case studies have shown that the solid waste management is a common aspect that many institutions focus on.
