Abstract:
Nowadays, the quality and quantity of water are decreasing and suffered a violation of order as an impact of overexploitation and the living things behavior. The deviations occur as the impact of overexploitation of human activities that ignore environmental aspects. Mandin Mangapan Waterfall in Niwak Hamlet Paramasan Atas Village is one of the potential forest products in form of environmental services. For a long time the people of Niwak Hamlet, Paramasan Atas Village have used Mandin Mangapan Waterfall to fulfill the water needs as a source of clean water needs. The purpose of this study was to analyze the quality of water-based on physical, chemical and biological parameters and to determine the suitability of water quality as well as describing the management of Mandin Mangapan Waterfall by forest management unit. The results indicate that designation of Mandin Mangapan Waterfall was classified to water quality class 2. That matter showed by, physically with indicators of temperature, color, smell and taste the water was a good quality so that means the requirements to be used as a source of clean water. From the results of laboratory testing, it shows that the water quality is relatively good in terms of chemical parameters with indicators of pH, Nitrite, Ammonia, Alkalinity and Sulfate which is classified in water quality class 1. Meanwhile, in terms of biological parameters, Mandin Mangapan Waterfall is polluted by bacteria. This is indicated by the presence of total coliform and fecal coli content in the water but does not exceed the water quality class 2 standard threshold and can be used as drinking water for conventional drinking water treatment.
