New and renewable energy sources today and in the future are human needs that need to be sought and explored from all existing nature, especially in countries with many sources of application, such as Indonesia. Indonesia is an archipelagocountry that has a vast nature with abundant alternative energy sources such as river flow, irrigation which can be usedas a source of energy for pico-hydro power plant. The purpose of this study was to determine theperformance of pico-hydro with a test model for the position ofnozzle position mounted on the pico-hydro usingscrew Archimedes turbine. The research method is carried out by direct experimentation from a tool that has been made using water fluid that iscirculated continuously as if in actual operating conditions. The results of this research show that the positioning of the nozzle distance as the water output to drive the turbine blades affectoperational results obtained. The farther distance fromnozzle position tothread, the power and rotation also decrease, on the other hand, ifnozzle is tooclose, the water sprayed bynozzle causes a back force of water so that the results are not optimal. In this research, the greatest power is generated at a nozzle distance of 4 cm, which is 230 Wattat a flow rate of 24 m3/h, and the lowest power is obtained at 44 Wattat flow rate of 2 m3/h where this position is ideal for pico-hydro installation.The best turbine shaft rotation in this study was produced at a nozzle distance of 4 cm which is 195 rpm, in this condition the spray of water flowing out of the tip of the nozzle towards the screw blade of the first part of the turbine which hits the sidelines of the screw occurs without resistance.
