Due to the change of land use, Ciliwung watershed suffered from physical degradation. Considering the increasing land use change along the Ciliwung watershed, it was necessary to perform a research on land use change and its impact on the river water quality (BOD, COD, DO). The land-use forms were divided into six categories: waterbody, bareland, forest, built-up area, agriculture and paddy field. The level of correlation was measured by Pearson correlation. The change of land use of waterbody, bareland, forest, built-up area and dry land agriculture influenced the river water quality. Waterbody had positive effect on water quality, while bareland and built-up area had a negative effect on water quality.Keywords

The aim of this research was to use tilapia farming waste as a nutrient for plant growth in recirculation systems in order to make use of water efficiently and to reduce pollution materials entering the aquatic environment. Aquaculture wastes such as residual feed and faeces, after experiencing decomposition, can be utilized as a nutrient supply for plants. During the 35 days of study, butterhead lettuce could grow well relying on the supply of nutrients from fish farming waste. Relative growth (RGR) of P2 treatment (10 pot plants) was 0.07 ± 0.02. It was almost the same as in the treatment of P3 (20 pot plants) amounted to 0.07 ± 0.01. Similarly, the specific growth of butterhead was of 7.49 ± 1.21 in P2 and 6.86 ± 1.02 in P3. The use of tilapia fish farming waste as a nutrient on water recirculation system was able to support butterhead lettuce growth.Keywords
