博士 === 國立成功大學 === 水利及海洋工程學系 === 103 === The relationship between land use and water quality was complex and likely to be site-specific, and more work was required to quantify this. This paper first reviewed the water quality status using three WQI methods, and analyzed by using Principle Component Analysis (PCA) and Cluster Analysis (CA) to reduce data of some water quality parameters, as well as to group the various waterbodies based on their water quality characteristics. It thus presented a comprehensive assessment of watershed and waterbody conditions in Depok Area, and their relationship with each other. An Aquaculture Water Quality Index (AWQI) was developed for use in an aquacultural context. The selected water quality parameters were representing the integration of physico-chemical and microbiological properties of aquaculture lakes. The AWQI developed in this work can be used as an effective, low-cost water quality monitoring program for developing countries. Because AWQI emphasized the simplicity and understandability as it must communicate to decision makers and the experts. Waterscape lakes also considered in this study because they played an important role in understanding aesthetic value of lakes. The current study implemented an enhanced visual quality assessment method by using a video-questionnaire to assess the aesthetic value of multi-purpose lakes in Depok Area, Indonesia, based on the perceptions of respondents. The results showed that the video-questionnaire method was quite efficient, easy to use, and understandable in identifying and measuring aesthetic value in relation to perceptions of bio-physical attributes. The final purpose was to design a conceptual framework of integrated evaluation methodology for aquaculture lakes preservation in Indonesia.
