Abstract

Batu City, which is famous as a tourist city, is not only an urban area. Most of the Batu city area is a rural area, especially the northern area which is included in the Bumiaji sub-district. As a tourist area, Batu City has a large enough economic potential to improve the welfare of its people. Most of the people of Batu city who live in rural areas are fruit and vegetable farmers. Pandanrejo village in Bumiaji sub-district is an example of a strawberry-producing village in Batu city. Various problems are faced by strawberry farmers in Pandanrejo village. One of them is related to the uncertain weather conditions in their village. The ITS Physics department team provides solutions related to these weather conditions with an innovative climate conditioning technology that can be applied in agriculture. This technology is a smart greenhouse in which there is control of environmental conditions for strawberry plants. With the application of smart greenhouse technology, it is expected to increase the productivity of strawberries and the welfare of the farming community of Pandanrejo village, Batu city.

Abstract

Electrical energy has become the main need of society. PLN manages the supply of electrical energy in Indonesia as the State Electricity Company. The problem is that not all areas of Indonesia are covered by the PLN electricity network. Various energy sources can be converted into electrical energy in remote areas not yet reached by the PLN network. One example of this energy source is micro hydro energy, energy from river flows that are not too strong. The equipment for converting micro hydro energy into electrical energy is called MHPP. This research is part of the application of MHPP based on Archimedes screw turbines as a source of electricity for areas near river flows that are not yet accessible to river flows. The focus of the research is to study the effect of the turbine elevation angle on the output electrical power of the MHPP. This research aims to determine the optimum values of rotation, torque, voltage, current and electrical power produced by an Archimedes screw turbine MHPP design with variations in turbine elevation angles of 20°, 25°, 30°, 35° and 40°. The MHPP design studied consists of 3 blades, a gearbox ratio of 2.8:1, a water flow rate of 6.34 liters/second, and a low rpm BLDC generator type. The optimum rotation is 1001.38 rpm at an elevation angle of 35° and the optimum torque is 1,738 Nm at an elevation angle of 40°. The optimum voltage is 14.84 V, the optimum current is 0.670 A, and the optimum electrical power is 7.861 W at an inclination angle of 40°.
