The supply of electrical energy in Tarakan City, North Kalimantan, still relies on diesel power which uses a limited number of petroleum energy sources. There is a need for research related to renewable energy sources that have the potential to become alternative energy for the people of Tarakan City. Water is an energy source that has great potential to generate electricity. The energy source that should be taken into account is micro-hydro which can be used as a Micro-hydro Power Plant (PLTMH). A survey of micro-hydro sources in Tarakan City, precisely in the Karungan area, East Mamburungan Village, has been carried out with the direct measurement method of water discharge and the relationship with the power generated. The result shows the water source has a discharge 0.00034 m3/ s, the water velocity of 0.035 m/s and generates power only up to 1.1 watts. Based on the power obtained, the water source in this place cannot be used as a source of micro-hydro energy, but has the potential as a source of pico-hydro energy.

FEASIBILITY STUDY OF MINI HIDRO POWER PLANT IN THE RIVER MANULA PUGUNG COUNTRYDISTRICT OF WEST COASTAL LAMPUNGRosnita Rauf*), Helny Lalan, and BudimanDepartment of Electrical Engineering, Faculty of Engineering & Planning, Ekasakti UniversityJl. Veterans Dalam No. 26 B, PadangAbstractThe increase in demand for adequate supply of electricity increases with the increase in population. The energy source used today is from PT. PLN Persero. To generate electricity to this day is still dominated by fossil fuels, which is a source of energy that can not be renewed and not environmentally friendly. The Mini Hydro Power Plant is a renewable and environmentally friendly energy source that has the potential to replace fossil fuels. In this research, a feasibility study of mini hydro power plant which is located in West Coast Pesisir Regency of Lampung. This feasibility study, which we need to measure is the number of reliable water debit contained in one of the rivers of Bukit Barisan Selatan National Park (TNBBS). The results showed that Manula river water discharge was Q = 20,32 m3 / s and Beda height or Head = 98 meter able to generate minimum power equal to 17,97 MW.

Hydro Power Plants

The dependence of power plants on energy sources such as diesel, natural gas and coal is almost 75%, encouraging the development of renewable energy in an effort to meet the electricity supply. One of them is the micro hydro power plant by utilizing the potential of existing water. The working principle of PLTMH is to change the potential energy of water into electrical energy. In this final project has been designed modeling of micro hydro power plant by using screw turbine (Archimedes Screw). The turbine used resembles a drill bit, with a diameter of a turbine of 26 cm, a screw width of 10 cm, and an amount of 10 pieces of blade. Measurements made on the modeling of micro hydro power plants include: water discharge, turbine rotation, generator rotation, voltage, current, torque and generator output power and efficiency. The parameters are measured by changing the water fall on the turbine from the position of the turbine head angle 00, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 700, 800  and 900 . The result of measurement that has been done on the parameters of micro hydro power plant modeling, obtained the highest measurement result at the corner of turbine head 400. The output power generated is 10.92 watts, torque is 0.60 Nm and efficiency of 14%. The results obtained are still low because the turbine rotation is less able to rotate the generator, where the generator torque is greater than the torque in the turbine. This is influenced by the small water discharges in the modeling of this micro hydro power plant.

Issues of the contraflows formation in the Votkinsk Reservoir (the middle one in the sequence of the Kama reservoirs) have been studied. The water discharge regime through the Kama Hydro Power Plant determines the contraflow occurrence. The importance of the contraflow issues is caused by the risk of contaminated waters input to water intakes located upstream in respect of the waste water outlets. One of the major industrial agglomeration, namely the Perm-Krasnokamsk cluster with numerous water intakes and waste water discharge points, is located in the upstream part of the Votkinsk Reservoir with is the downstream reach of the Kama Reservoir. On the basis of assessment of the contraflows scale and the consequences for water users the water/economic and environmental limitations are set for the power plant operation regime including sanitary discharge volumes. The contraflows have been simulated as a result of digital solution of the Saint-Venant equation in 1D-definintion with input of the first type boundary conditions directly in the vicinity of the Votkinsk Power Station dam. We have assessed the reservoir morphometry role in the contraflows formation. Outputs of the comparative experiments performed at different schematic models of the Votkinsk Reservoir have shown that reflection of the level lowering straight wave from the Votkinsk Power Station dam is the determining factor of the contraflows formation rather than peculiarities of the morphometry. When decreasing the period of water discharge to the downstream reach the zone of contraflows formation is displacing towards the Votkins Power Plant dam.

Research has been carried out to regulate / control the rotation of the turbine for this type of micro hydro power plant (PLTMH). This research was carried out during the dry season where water discharge greatly affects turbine rotation. This tool utilizes an optocoupler sensor, servo motor and 2x16 LCD. This system works based on the turbine rotation speed that is read on the sensor then controls the slope of the water fall using a DC motor. If thewater speed is low, the servo motor will turn CW up to a maximum slope of 75 degrees to produce maximum rotation and maximum power. This research does not focus on the magnitude of the resulting current source and the amount of water discharge

The city of Jambi is an area batanghari river, the study of the utilization of renewable energy, especially hydro power through the tributaries should be considered for the planning of Micro Hydro Power Plant (PLTMH). Water conditions that can be utilized as electricity generating resources have a certain flow capacity and altitude of their drainage system. A major problem in hydroelectric generation is the availability of river water discharge as a propulsion energy. Therefore, certain techniques are needed to predict the potential flow of river water at all times or the river's main discharge that can be used for hydro-electric power generation, no long-term rainfall and critical watershed conditions can cause water flow the stream becomes small and even becomes dry. Manual river flow measurements over time can only represent the volume of river flow at the time of measurement. Changes that occur due to the occurrence of rain at a later time, or decrease in river discharge due to decreased soil water savings, can not be monitored properly it is necessary to plan a continuous discharge for the capacity of generator turbine rotation by calculating the electrical capacity of the generator which can be generated optimally
