<![CDATA[ In general, a water pump's main source of power is to use electrical energy to transport fluid to a certain place. However, electrical energy is the main problem in rural areas to power the pump. Therefore, technological innovation is needed so that the pump can still be used even though it does not have an electricity source.The main objective of the research is to find out and identify the minimum water availability needed to run PATM. This research was carried out on the South Dulamayo river using PATM made of galvanized steel construction material in the form of a pipe with a diameter of 3 inches and a length of 1.4 meters. The method used is by changing the damper opening by 100%, 50% and 25%.Based on the testing, the results of the research Machine Testing are obtained. The water pump without an engine produces a quantity of water of 3 liters for 100% opening and the lowest is 1 liter for 25% opening. The flow rate (Q) produced is respectively 9.1 m2 for 100% opening. %, and 6.8 m2 for 50% openings and the lowest is 4.5 m2 for 25% openings. The time obtained to get the fastest amount of flow is 60 seconds and the longest is 120 seconds.]]>
