    Abstract: Pico hydro is a power plant that uses water as turbine propulsion that can generate electricity by a generator. This research will discuss the numerical analysis of the effect of the number of threads on the turbine blades. The analysis process uses the Computational Fluid Dynamic method and the software used in ANSYS FLUENT. In variation 1 uses 9 threaded blades, variation 2 uses 6 threads, variation 3 uses 4 threads. Based on the simulation results in variation 1 with the number of blades 9 threads, the highest torque at TSR 12 is 0.00984111 Nm, power is 0.007671419 Watt. The water pressure entering the turbine blades in variation 1 is 0.097098 Pascal and the water pressure coming out of the blades is 0.047954 Pascal, there is a total pressure drop of 0.4914 Pascal. Based on the torque and power values of the Archimedes turbine in the three variations, it is known that variation 1 has the best performance followed by the other two turbine variations.

    Abstract: Designing a vehicle frame, selecting materials and determining the factors of safety and comfort are a very important thing very important. So that the safety of the driver is a concern important when the car has an accident. Research methods used is a simulation using the method finite element. Impact testing modeling mechanism that done is full-width frontal impact. This crash test variation was carried out on the frame structure of the E – Falco electric car. The research compares the two materials to be applied to the frame namely ASTM A36 and JIS G3101 materials. Variation of speed applied to the impact testing of this research is 40 km/hour, 60 km/hour, and 100 km/hour. After the analysis process is carried out, obtained the maximum deformation of the frame on the ASTM A36 material with a speed of 100 km/h is 176.57 mm and at JIS G3101 material is 175.09 mm. The maximum stress value obtained in a frame with ASTM A36 material with a speed of 100 km/hour is 4488 MPa and the JIS material G3101 is 4475 MPa. The maximum strain value obtained frame with ASTM A36 material with a speed of 100 km/hour is 2.46E-02 and the JIS G3101 material is 2.52E-02. The frame with ASTM A36 material has a safety factor of 2.4 and the JIS material G3101 has a safety factor of 3.1.

    Performance Analysis of DN1750 and DN1800 Electric Submersible Pump for Production Optimization on the Oil Well
    Institute for Research on Innovation and Industrial System (IRIS) ; 2022

    Abstract: Abstract. Electric Submersible Pump (ESP) is an artificial lift method to lift fluid from the reservoir to the surface with a certain production rate, the ability of the pump to lift a certain fluid to the surface is adjusted to the capacity of the well itself. Over time, the production of oil wells will experience a decrease in the rate of production which will cause a decrease in pump performance. In several oil wells, well maintenance activities have been carried out. Therefore, in this study, an analysis of pump performance and optimization of the ESP pump was carried out using the Nodal Variable Speed Drive analysis method. The goal is to determine the production capacity of the oil well and determine the pump speed as desired. Oil well performance analysis and optimization of the ESP pump were carried out by mathematical calculations with the optimization results obtained that the DN1750 pump was installed at a frequency of 50 Hz, 55 Hz, 60 Hz, 65 Hz, and 70 Hz. The Hz number does not cross the desired flow rate line (q optimum) or is outside the desired fluid flow rate range by the oil well so it can be interpreted that based on the observation of the optimization process, the condition of the DN1750 pump is not working optimally so that the oil production capacity is not optimal. The DN 1800 pump at a frequency of 55 Hz with a speed of 3300 rpm is in accordance with the production capabilities of oil wells so that the appropriate pump is obtained and is expected to work at optimum conditions. At a frequency of 55 Hz with a speed of 3300 rpm successfully cut the desired flow rate line (q optimum) from the observed oil well characteristics or is in the range of fluid flow rates desired by the oil well, which is 1936,698 Barrels Per Day (BPD) with wellbore pressure (PWF) 629 psi.

    Abstract: The motor releases torque and power to drive an electric car by carrying the load from a start position until it travels at the desired speed. The KMLI E-Falco electric car uses a BLDC type electric motor with a power capacity of 2 kW. To find out the amount of torque of a 2 kW BLDC motor when driving with variations in speed, it can be done by manual calculations using the torque equation and doing a dynotest test. The dynotest results show that the motor torque at the speed: 1 km/h is 1 Nm, 10 km/h is 131 Nm, 13 km/h is 228 Nm, 20 km/h is 225 Nm, 30 km/h is 219 Nm, 40 km / h is 188 Nm, 50 km / hour is 145 Nm, 60 km / h is 113 Nm, and 70 km / h is 85 Nm. From the results of the dynotest, it shows that the peak torque occurs at a speed of 13 km / h at 228 Nm. Racing software installed in the controller can increase the motor torque by four times at a speed variation of 13-70 km/h based on the results of the dynotest above. Keywords: motor, BLDC, torque, speed, acceleration.
