Abstract

The use of electrical energy is getting bigger along with the increasing population growth and variousfacilities that depend on electrical energy. However, the availability of electricity from PLN is notsufficient to meet the needs of the Indonesian people. Therefore, it is necessary to conduct researchon the utilization of potential renewable energy sources which are widely owned by our country,Indonesia, one of which is river flow and irrigation canals. For this solution, a PLTMH (Micro HydroPower Plant) is made, a small-scale power plant that uses hydropower as its energy source. Thepurpose of this study was to determine the performance characteristics of the prototype Snail-Lieturbine at MHP. The research method used is first to look for data by studying literature related toMHP and existing Micro Hydro Power Plant prototypes, secondly collecting data by observing anddirectly testing the parameters on the prototype of the Power Plant. Micro Hydro Power. This researchwas conducted to determine the characteristics of the Snail-Lie turbine prototype at a Micro HydroPower Plant, namely by measuring parameters based on the angle of the nozzle and nozzle armssuch as the turbine rotational speed, the rotational speed of the generator produced by the turbine,the resulting current and voltage then calculating the power from the turbine which has the highestrotating speed. The conclusion that can be drawn from the results of the measurement of theparameters is that the Snail-Lie type turbine the larger the nozzle arm angle, the faster the rotationspeed of the turbine and generator. The faster the speed of the turbine, the greater the current andvoltage generated. The faster the rotation speed of the turbine, the greater the torque produced.

Abstract

Grounding is a basic measure to guarantee the security, reliability of the operation of the system and ensure the safety of humans and living things when there is a ground disturbance in the electric power system. In research on the earthing system, what must be considered is the nature of the soil as the place where the grounding system will be installed. The difference in soil type and acidity will affect the safety quality of the grounding system. This study discusses the acidity of the soil to get an appropriate earthing system on different soil textures. The research method used is direct measurement of acidity and resistivity of different soil textures. As well as analyzing by calculating the optimization of 4 types of earthing system namely Rod, Multiple Rod, Plate, Mesh and Grid-Rod technically. The results of the analysis found that each soil has a different level of acidity. The stronger the soil acidity, the smaller the type of resistance produced. A good acidity level is used for the grounding system (pH <7). Unequal acidity causes different types of soil resistivity, so the shape of the grounding system will vary according to the texture and type of soil.
