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.

Based on the performance test results, Pico-Hydro Power Station can work well. This can be seen from the indicators of high water flow discharge can rotate the turbine quickly during the rainy season the flow of water will be higher turbine will also spin faster. Water discharge is very influential on the rotation of the generator, if the water discharge is high then the charging will be faster. Conversely when the water discharge decreases the charging will be long. The average water discharge of 0.061 - 0.065 can rotate the 371 rpm generator producing an average voltage of 17.5 volts. At a voltage generated from an inverter of 220 Volts can supply a number of 5-sized lamps 15 Watt. The result of the generator test produces a voltage of 12 V AC with a current of 2 Ampere converted to an inverter DC voltage to AC to 220 V with 100 Watt power. Keywords : pico-hydro, 3 phase AC generator,  water discharge AbstrakPenelitian ini bertujuan untuk merealisasikan sebuah Pembangkit Listrik Tenaga Pico-hydro yang dapat digunakan untuk penerangan jalan seputaran kebun salak, serta mengetahui unjuk kerja dari pembangkit listrik tenaga pico-hydro yang nantinya dapat digunakan untuk kebutuhan energi listrik seperti penerangan jalan.

Saat musim hujan aliran air akan semakin tinggi sehingga turbin juga akan berputar lebih cepat. Debit air sangat berpengaruh terhadap putaran generator, jika debit air tinggi maka pengisian akan lebih cepat. Sebaliknya saat debit air menurun pengisian akan lama. Debit air rata-rata 0,061 - 0,065 dapat memutar generator 371 rpm menghasilkan tegangan rata-rata 17,5 volt. Pada tegangan yang dihasilkan dari inverter sebesar 220 Volt dapat mensuplai sejumlah lampu 5 berukuran 15 Watt.

Land degradation on the upstream of watershed will affect hydrology condition in a way that it will disrupt the sustainability of its existing micro hydro. The purpose of this study is to evaluate micro hydro power plant in central Java toward sustainability against hydrology condition of watershed. This study is using River Regime Coefficient (RRC) approach where hydrology of watershed with coefficient value less than 50 is classified as non-critical, between 50 and 120 is moderate and more than 120 is critical. Result of the study that was done on 33 micro hydro power plants scattered on 9 watersheds is showing that there are 2 power plants on 2 watersheds have hydrology condition in non-critical status (9.09%), 1 power plant on 1 watershed is in between critical and non-critical status (3.03%), 21 power plants on 3 watersheds are in between critical and moderate status (63.64%), 8 power plants on 6 watersheds are in critical status (21.21%) and 1 power plant on 1 watershed is in between moderate and critical status (3.03%).

This work is within the scope of set of consultancy studies made for Portuguese islands. It focuses on the integration of Pumped Storage Power in isolated islands. The paper starts to address several power systems circumstances about two Portuguese islands on the energetic level. For each of these islands, an independent examination of the conditions to install a reversible hydro power plant is accomplished. Therefore, the energy volume to be stored due to excess of renewable generation and the ideal power and number of the pumps and turbines to be installed were identified and evaluated for the sake of using the produced energy surplus as to be pumped and later generated. The paper enhances the importance of storing energy in the operation of isolated and small systems with considerable amount of intermittent power resources as well as the conditions for the viability of installing new exploitations of this kind.

Microhydro power plant (MPP) is a small-scale power plant that uses water energy. The process of energy change occurs in a device called a synchronous generator. when the synchronous generator is given an arbitrary load, then the voltage will change. These results cause voltage and frequency instability. This research was conducted to analyze the voltage and frequency instability in MPP. The research method used in this research is descriptive quantitative approach in the village of Soko Kembang, Petungkriyono District, Pekalongan Regency, Central Java. This study provides an overview and explanation of the problems regarding the voltage and frequency instability of Micro Hydro Power Plants. The results of this study are the highest and lowest voltage / frequency instability values, namely 235 volts / 51 Hz and 160 volts / 44 Hz, due to the influence of changes in load current, which can affect the rotational speed of the generator changes, resulting in unstable voltage and frequency generated by the generator, the rotational speed of the generator changes, resulting in unstable voltage and frequency generated by the generator. The solution is  add water power to rotate the shaft of the turbine and generator to be tighter, so that it can reduce the value of the decrease in electric power by losses to the turbine and generator. Large electric power can increase voltage and frequency without having to adjust the load, and the need for improvement of the ELC system in order to get a more effective value of voltage and frequency stability.
