Abstract

The research objectives are to identify the performance efficiency of Centrifugal Pump No. 3, determine the headloss value, and compare the available NPSH with the required one. The method used is quantitative with an experimental approach to collect pump performance data. The results showed that the pump performance efficiency was 9.9%, headloss was 0.003521 m, total pump head = 9.19 m, hydraulic power = 0.49 kW, pump power = 5.1 kW, available NPSH was 9.92 and the required NPSH was 2.3 m. The application of preventive maintenance includes identifying components experiencing wear and tear, periodic maintenance of suction and discharge piping, routine purging to reduce head losses and checking the condition of the pump suction to anticipate cavitation factors. The application of preventive maintenance includes identifying components that are experiencing wear and tear, periodic maintenance of suction and discharge pipe installation, routine flushing to reduce head losses and inspection of pump suction conditions to anticipate the cavitation factor. Keywords: centrifugal pump, PPSDM, head loss, preventive maintenance

Abstract

Gold mining activities on Buru Island legally or illegally cause water at several coordinate points to be contaminated with heavy metal types of mercury (Hg). Knowing the level of mercury in water is important to determine whether or not water can be consumed. This study aims to determine the level of mercury spread and how to overcome environmental damage due to mercury in water using eucalyptus charcoal. The method used in this study is quantitative by collecting data by observation, interviews, and literature studies. The variable in the study was filtering as a tool to reduce polluted mercury levels. The results of this study were carried out at 3 coordinates and 2 of the 3 coordinates showed a decrease in mercury levels, namely in the coodninat of the father's house, sub-district and village hall successively decreased by 18 μg / L and 2 μg / L. From the results it can be concluded that the level of mercury levels does not exceed the Quality standard figures placed according to the Ministry of Environment and Forestry No.Kep 51 of 2004 and eucalyptus charcoal can reduce mercury levels deposited in water. Based on the results of the research conducted, it turns out that there are still many shortcomings using this method. For future researchers who want to conduct similar research, in order to complement by answering the shortcomings of this study. Keywords: mercury, eucalyptus, filter
