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.

ABSTRACT The study of hydropower potential focuses on hydropower development in Sumatra (4,408 MW), Java (4,595 MW), and Sulawesi (3,240 MW) is in line with the actual development of the hydropower industry. These three islands cover 95% of the viable hydropower potential. Meanwhile, the potential of PLTMH is 770 MW and about 30% has been developed. Most of the Microhydro (<1 MW) and Mini hydro (1-10 MW) are targeting rural electrification with the greatest potential in Papua and Sumatra. Therefore, in the concept of optimizing water use and aligning Water Food Energy Nexus, apart from modernizing irrigation, it is also necessary to develop the use of PLTMH in irrigation networks to generate electricity through a Micro Hydro Power Plant (PLTMH). In practice, the use of irrigation networks for the development of PLTMH electrical energy does not interfere with the flow of irrigation water used to serve the needs of the farming community because the MHP technology used as a power plant only utilizes irrigation water flow with a certain volume, both in the waterfall and the aspect of its flow rate. To find out the completeness of the readiness for the utilization of irrigation networks for MHP, it is necessary to conduct an initial assessment of the preparation process has been carried out. One of the assessment methods that can be used for the construction of MHP are to use a standard sustainable hydropower assessment protocol known as the Hydropower Sustainable Assessment Protocol (HSAP). Key words: power plant, micro-hydro, irrigation network, assessment protocol, HSAP   ABSTRAK Studi tentang potensi tenaga air menempatkan fokus pada pengembangan tenaga  air di Sumatera (4.408 MW), Jawa (4.595 MW), dan Sulawesi (3.240 MW), yang sejalan dengan perkembangan aktual industri tenaga air. Ketiga pulau ini mencakup 95% dari potensi PLTA yang layak. Sementara potensi PLTMH adalah 770 MW dan sekitar 30% sudah dikembangkan. Sebagian besar Mikrohidro (<1 MW) dan Mini hidro (1-10 MW) menargetkan elektrifikasi pedesaan dengan potensi terbesar di Papua dan Sumatera. Oleh karena itu, dalam konsep optimalisasi pemanfaatan air dan penyelarasan Water Food Energy Nexus, selain modernisasi irigasi, juga perlu dikembangkan pemanfaatan PLTMH pada jaringan irigasi sehingga menghasilkan listrik melalui Pembangkit Listrik Tenaga Mikro Hidro (PLTMH). Pemanfaatan jaringan irigasi untuk pengembangan energi listrik PLTMH dalam prakteknya tidak mengganggu aliran air irigasi yang digunakan untuk melayani kebutuhan masyarakat petani sebab teknologi PLTMH yang digunakan sebagai pembangkit listrik, hanya memanfaatkan aliran air irigasi dengan jumlah volume tertentu, baik pada terjunan maupun pada aspek kecepatan alirannya.  Untuk mengetahui kelengkapan kesiapan pemanfaatan jaringan irigasi untuk PLTMH, perlu dilakukan penilaian (assessment) awal terhadap proses persiapan yang telah dilakukan. Salah satu metode penilaian yang dapat digunakan untuk pembangunan PLTMH adalah dengan menggunakan standar protokol penilaian tenaga air berkelanjutan atau yang dikenal dengan  Hydropower Sustainable Assessment Protocol (HSAP).

One form of water energy utilization is done by building a Hydroelectric Power Plant (PLTA) in Indonesia, the Bakaru PLTA is one of the projects within PT. PLN (Persero). This project is a Hydro Power Plant Master project with a SULSELRABAR transmission located 246 km from the city of Makassar. The operation of the Bakaru hydropower system is certainly expected to work optimally, reliably and efficiently. Therefore, evaluation or data on the performance of the generator itself is needed. This study was conducted to determine the condition of the Bakaru hydropower plant based on the equivalent availability factor (EAF) and Net Capacity Factor (NCF) and Cost of Production (BPP). The data used is operating data on the Bakaru hydropower plant for 1 year. The data was obtained by using the documentation technique, while the data analysis was carried out using the Microsoft Excel program. After conducting research, it can be concluded that the condition of the Bakaru hydropower plant in 2017 is considered normal, seen from the EAF value reaching 94.15% and the average EFOR value of 2.4% with the number of Service Hours (SH) of 16,912.93 hours from 2 units. with the percentage of Service Hours to Period Hours reaching 96.53%. Meanwhile, the Net Capacity Factor of the Bakaru hydropower plant in 2017 reached 85.83%, with a total gross energy production of 945,372.50 MWh. This value exceeds the target that has been set.


Electrical energy can be obtained by burning coal (thermal power plant), by using nuclear fuel (nuclear power plant) or by using the power of water (hydro power plant). In these cases, the energy obtained by the sources put a shaft of an electrical generator in motion. The generator generates electrical energy – see Figure 1. In the installation, excitation system for the generator is used. The system turns on an uncontrolled rectifier, thyristor-controlled rectifier or AC thyristor regulator dependent on the generator type. The obtained energy is transmitted using a transmission system towards consumers. The transmission yet is made mainly in high-voltage AC energy form (HVAC). In different parts of the transmission network the voltage value may be different. There are so-called high-voltage (420 kV, 220 kV, 110 kV, etc) and medium voltage (20 kV, 6.6 kV, etc.) systems. General consumers consume electrical energy from so-called low-voltage systems (230V, 50Hz or 110V, 60Hz). During the transmission the type of energy does not change, only the value of the voltage changes using transformers.
