Learned about the use of water resources as a micro hydro power plant is very importantto be carried out by Electrical Engineering students at Udayana University. At this time atConvertion Energy Laboratory there was not been a practicum about Mycro Hydro Power Plandue to the unavailability of guide practicum module and micro hydro power plant prototypes.Therefore in this research was design and build a Prototype of Microhydro Power Plan wich had18 buckets where had 5 cm width, 4,47 cm length, 1,6 height and the tickness was 0,28 cm.This prototype can made 4,5 L/s water discharge, 9,809 W Power, and the torque was 0,26 Nm. So that prototype had 1,48% efficiency. To make this prototype as a complete practicummodule was arranged practicum guide modules that was explain abaout Characteristic of MicroHydro Power Plan with Pelton Turbines.

Utilization of irrigation flows as a source of electrical energy is not too much, because irrigation flows have low head heights so it's hard to do the design and type of power plant used. In addition, the water discharge in the irrigation canal is also a problem because the water seed in the irrigation canal is not always constant which is influenced by seasons and weather factors. In this study, we will discuss the effect of adding a gearbox to the Archimedes screw turbine on the output value of the generator such as electric current, voltage, efficiency, and torque. This micro hydro power plant uses an Archimedes screw turbine which has 9 blades with an angle of 24o and a blade thickness of 0.25 cm. on the gearbox used using a spur gear type which has a total ratio of 4: 9. The results of research conducted on irrigation lines in Munggu Village, Mengwi District, Badung Regency, got the highest rotation results, namely 160.7 rpm at the turbine, 882.4 at gearbox and 1013, 8 rpm on the generator. The highest voltage and current generated by the generator are 11.15 volts and 0.66 amperes. The torque obtained is 0.45 Nm and the highest efficiency is obtained at 0.00638%.

At present the power plant has a high dependence on energy sources such as diesel, natural gas and coal, while its energy source in nature is increasingly scarce, this situation encourages the development of renewable energy, one of which is in micro hydro power plants. This study aims to determine the effect of the width of the work triangle on the highest rpm produced. the fall of water on the pinwheel is set from the position angle of the nozzle 00, 150, 300, 450, 600, 750 and from the angle of the nozzle 00, 50, 100, 150, 200, 250, 300, 350 and 400 on the semicircular blade turbine, triangle blade turbine , and fin blade turbines. Semicircular turbine blade, working triangle area produces greater rpm at position of angle nozzle 00 and angle of nozzle 250 with area of work triangle 360,36 cm2, where the position produces 216 rpm at windmill rotation and 1626 rpm at generator rotation. When the nozzle position angle 150 and the nozzle angle 200 with the working triangle area 264.27 cm2, produce 221 rpm at the pinwheel rotation and 1711 rpm at the generator rotation. while at the nozzle position angle of 300 and the angle of the nozzle 100 the area of the triangle works 134.37 cm2 and produces 173 rpm at the spinning wheel and 1307 rpm at the generator rotation. on the triangle blade turbine and fin blade, the working triangle area does not affect the rpm produced.

Micro-hydro power plants using vortex turbines have the advantage that their operation can be carried out at low levels of falling water or head. One of the problems that exist in vortex turbine is there is no equation to determine the maximum output generated by the number of blades used. Based on the problems described, a prototype of micro-hydro power plants using vortex was made to test the variations in the number of blades to get the best efficiency. The prototype test in this study used a turbine with various number of blades of 3, 5, and 9 blades. Based on the research conducted, the increase of micro-hydro power plant prototype performance equals to number of blades used. When the system was set with a discharge of 4.5 liters per second paired with a turbine consisted of 9 blades which produced 303.8 rpm of turbine rotation before coupled by the generator and 230.5 rpm after coupled by the generator, the generator rotation was 653.5 rpm, the generator output voltage was 8.29 Volts, generator current output was 0.046, generator power output was 0.387 Watt, torque was 0.0393 Nm, and the highest efficiency was 2.92%

Vortex turbine is a reaction water turbine that can utilize energy from low headed waterway. The power output of generator on microhydro power plant will differ depend on the input parameters used, such as water flow rates. Hence, this research goal is to find out the power output of generator from various water flow rates with an artificial waterway on a vortex turbine within the microhydro power plant prototype. This research consist a free variable of water flow rates of 2,5 l/s, 3,5 l/s, and 4,5 l/s using 9 blades turbine and paralel load lamps. From the experiment, raises of water flow rate is proportional to the increase of generator’s power output. The power output generated by each water flow rates used are 0,085 W at 2,5 l/s water flow rate, 0,256 at 3,5 l/s, and 0,387 at 4,5 l/s. Based on the experiment, it can be concluded that the increase of input water flow rate is equal to the increase of the power output generated by the generator. It is caused by the rotation of the turbine will be adjusted by the water flow rate used.

MHPP is a run of river hydroelectric power plant type, that does not require a large dam or water discharge, but rather diverts the flow rate of water into a channel. Vortex turbine utilizes whirlpool of water obtained from the spiral basin shape to push the turbine to rotate. The reason of this research was to decide the design of the MHPP prototype using a vortex turbine. This prototype is a miniature or laboratory scale. This research is designed to model the MHPP prototype using a Vortex turbine which is helpful for learning before it is implemented directly to the river. In this study, the prototype MHPP with vortex turbine was designed with a 0.3 m head, 1.5 dim input pipe, 4.5 L/s water flow, basin with an upper diameter of 40 cm, 40 cm height and 12 cm outlet and 41° cone angle. The runner blade design has 9 blades with a runner outer diameter of 15 cm, 5 cm neck diameter, and 5 cm runner width. This prototype is able to generate power of 0.387 Watt and has an efficiency of 2.93%.

These days technology has developed rapidly, almost covering all aspects in humas life for example is automation system. The automation system works without human intervension and complete all works independently. Existing technology can already be connected to each other via the internet network so that it can transmit or receive data automatically. The Internet of Things (IoT) can support automated systems by providing real-time information so that users can monitor the performance of these automated systems. This research was to develop rabbit cage by utilizing microcontroller as monitoring system. The system utilizing Internet of Things (IoT) as monitoring medium between users and devices to help users monitor their rabbit cage remotely. The design installed several sensors such as ultrasonic, temperature, load cell sensors, DS18B20 and water level sensors. This research used Arduino Mega 2560 as main microcontroller and NodeMCU ESP8266 as communication device between the tools and database. The tools use android application on user smartphone that fuctions real time monitoring for the cage. Based on the results of this research by using Arduino Mega as microcontroller board to controlling and monitoring rabbit’s cage has succesfully in monitoring the cage via internet through the NodeMCU ESP8266 intermediary according to the design.
