“…The rotation of the AST is low, around 60 until 130 rpm . A turbine with a low rotation is suitable to use a direct current (DC) generator because it still produces electricity [42][43]. However, based on testing, the alternating current (AC) generator generating higher power than the DC generator, the difference of 10% [41].…”

Electricity plays an imperative role in improving the rural or remote community economic growth and quality of life. The pico hydro type Archimedes screw turbine (AST) is considered an independent power plant in rural or remote areas. The advantages of the AST are friendly to aquatic biota, the high and stable efficiency (electrical efficiency of 30% to 49%), and can operate in a run of river conditions. However, although this technology has been studied ± two decades, there is still no theory explaining the relationship between conversion energy, the geometry of screws, and efficiency. Therefore, the development of Archimedes screw focuses on the role of a converter water energy categorized as the environmentally friendly power plant. Thus, this paper aims to describe the future work required for the AST so that the basic principles and empirical theories are found. Based on reviews, the AST design can use Rorres and Muller & Senior analysis, AC generators with a pulley and toothed belt transmission systems, and do not immerse the outflow bucket side in the water. Furthermore, for AST to be better, several studies need to be done such as the method of manufacturing precision screws, the effect bubbles in the bucket and how to avoid them, determination optimum of the head and screw length using the slope angle, and investigation of the ratio of the inlet velocity with the angular velocity of a wheel on performance to avoid overflow leakage due to loading.

“…It is because the first-level shaft with a small rotation will make the torque value larger. Furthermore, by taking into account the aesthetic dimensional factor due to the low turbine rotation and intention to get the turbine dimensions as compact as possible, the pulley-and-belt transmission system should not be used, as revealed in studies conducted by Budiarso et al [23,24]. If the pulley-and-belt transmission system is used, the dimensions will be very large because of using type C pulleys with more than two lanes, as illustrated by Joel and Bakthavastsalam [25] and Scott et al [26].…”

The use of energy, especially for daily needs, is important. Pico hydro is an environmentally friendly power plant model that can take advantage of low flow rates and generate electricity below 1 kW. The purpose of this research is to obtain the best performance of pico hydro with a screw-shaped turbine model or what is called Archimedes Screw Turbine. The research method was carried out experimentally by adjusting the angle of the Archimedes screw turbine shaft, namely 30°, 45° and 60°. Observations at a discharge of 15 m 3 /h with an angle of 30° provide information that the screw turbine power obtained is 111.4 W with an efficiency of 57%. For an angle of 45° the power is 165.7 W and an efficiency of 77% while at an angle of 60° it produces 186 W of power with an efficiency of 87%. The results of this analysis prove that the pico-hydro model with a screw turbine by adjusting the angle variation on the turbine shaft gives the conclusion that the greater the given angle is, the greater the obtained performance will be, in terms of power and efficiency.

“…Someone who is going to build the infrastructure for a hydropower plant model must meet several main requirements such as the flow of river water that has a good enough spring and an adequate place for the construction of a power plant in terms of the height and width of the river where generator is placed. Several references have also been put forward by researchers who are concerned with the field of hydropower, as has been done Budiarso et al, [10], Zitti et al, [11] presented his findings saying that the main part of the guide in the form of a nozzle has an impact on shaft performance for the turgo turbine type, so the nozzle model must be made according to the condition of its application [12,13]. The angle of Blade section is the most important component in water energy conversion system as tool that interacts directly with flowing water.…”

New energy and renewable energy are solutions that can be applied to meet energy needs, especially those that are environmentally friendly. Currently, people, especially those living around energy sources such as rivers and irrigation, can independently create renewable power systems to produce energy. The application of picohydro power generation technology is the best solution in the application of environmentally friendly, independent, and renewable technologies. The purpose of this study was to determine the best performance of the nozzle output diameter of 3", 4", and 5" on picohydro technology using an Archimedes screw turbine. The research method was carried out by means of a prototype experiment using continuously circulated water fluid. The data collection process starts from the water discharge from the flowmeter, the rotation of the turbine blade, the rotation of the transmission, the rotation of the alternator, the pressure in the pressure gauge, and the power generated. The research results obtained information that at the smallest diameter (3") the nozzle pressure to the screw tip is not optimal because the water released by the nozzle only hits part of the screw leaf side, so that the performance is not optimal where the turbine shaft rotation at a maximum discharge of 30 m3/h is obtained at 230 rpm, while if the diameter of the output nozzle is given (5"), a lot of water is sprayed by the nozzle and it fills the screw leaves, which causes water to also overflow onto the screw in front of it, so that the flow does not normally flow from each screw, and it is also possible that the size of the input screw is not proportional to the output screw turbine, where the maximum rotation at a discharge of 30 m3/h is obtained at 247 rpm. For the size (4") it looks higher when viewed from the data obtained, this condition looks ideal in the size ratio between the input and output nozzles so that the resulting flow is also right to drive the turbine screw. The shaft rotation results obtained are 269 rpm for a water discharge of 30 m3/h.
