Abstract

A boiler Is a steam-producing closed vessel that can convert chemical energy from fuel into pressurized steam. The steam is used as an electrical power source and for the processing of oil palm fruit. Researchers use direct observation methods to identify specimens and parameters. To analyze the efficiency of thermal boilers and Specific Fuel Consumption (SFC) using 100% fiber fuel and a combination of 70% fiber and 30% shell. From the results of this study, it is stated that using 100% fiber fuel produces 68.1% thermal boiler efficiency, and an SFC value of 13.37 kg/kWh is obtained. The combined fuel use of 70% fiber and 30% shell results in 74.2% thermal boiler efficiency and an SFC value of 10,98 kg/kWh is obtained. So that the efficiency of thermal boilers has increased by 6.1% and the SFC value has decreased by 2.39 kg/kWh.  The improvement in boiler performance and low SFC value is due to the high calorific value of fiber and shell combination fuel which is 12799.343 kJ/kg and low fuel consumption of 5492.53 kg/hour.

Abstract

Rack grate is a component composed of rack clip and rack bone arrangement that serves as a dropping cross-section media of coal and as a media of coal burned in the boiler.  As part of the main component, the rack grate can be regarded as one of the components that ensure the success of combustion in the boiler. Failure to this component will certainly interfere with the implementation of boiler operations. In addition to require the boiler to be shut down while repaired, in addition to requiring the boiler to be extinguished during repairs, the inoperability of the boiler makes the steam production process at the PLTU impossible and ultimately the electricity generation process cannot be carried out as usual. Damage to the rack grate component has a type of plastic deformation with variable loads and fluctuating heat, which means that the thermal stress in the system has reached the yield stress point. To find out the root cause of this component damage quickly and accurately, an analysis of the results of the implementation of engineering software in this case Ansys Workbench, and a comparison of actual operating data, and data design is the best choice. Lastly, by evaluating the optimum values of temperature, equivalent stress and strain, total deformation, input process parameters value can be controlled to the desired values, resulting in less stress concentration occurs, so that the damage to the workpiece can be reduced or even eliminated.

Abstract

Pompa adalah peralatan mekanis untuk meningkatkan energi tenakan pada cairan(fluida) yang dipompa dengan mengubah energi mekanis poros penggerak menjadi energi potensial dan energi kinetis fluida. Seiring berkembangnya teknologi, pompa digunakan diberbagai bidang termasuk pemakaiannya dalam bidang indsutri. Pompa Sentrifugal merupakan salah satu jenis pompa yang mempunyai lingkup penggunaan yang sangat luas terkait dengan head dan kapasitas yang dihasilkan. Pada kesempatan ini penulis mencoba memaparkan hasil penelitian tentang unjuk kerja pompa sentrifugal bila dilakukan variasi tinggi hisap pada pompa sentrifugal akan mempengaruhi kapasitas, Head, Daya Hidraulis dan effesiensi pompa sentrifugal. Variasi tinggi hisap dimaksudkan untuk mengetahui peningkatan performance pompa yang terjadi akibat penambahan tinggi hisap pompa. Menambah tinggi hisap pompa sangat berpengaruh terhadap kapasitas aliran air yang dihasilkan, hal ini juga akan mempengaruhi kerja pompa, kecepatan spesifik, daya dan efesiensi pompa. Sehingga dapat diperoleh titik kerja tertinggi pompa sentrifugal dengan Kapasitas (Q) 0,001180 m3/s, Head (H) 6,066 m, Daya Hidraulis (Ph) 70,008 watt, Effesiensi (ɳp) 26,51 %, hal ini dapat terlaksana bila diikuti penambahan daya dari motor penggeraknya.

Abstract

Radiator is a cooling system using fluid as a heat exchanger. How the radiator works by channeling the heat released by the motor engine is then absorbed by the radiator coolant fluid. The radiator device consists of a coolant inlet and engine outlet, a cooling fan mounted in front or behind the radiator, and coolant. Coolant in the radiator has a very important role in dissipating engine heat to the environment. In this study, I will analyze the different types of coolant variations, namely water, prestone antifreeze, Seiken, premix coolant DCK, and yamacoolant. on the cooling rate and radiator effectiveness using rotation variations of 1600, 3000,5000 rpm and measurement times of 1, 5, and 10 minutes on the Yamaha Nmax engine. The results of the research that have been carried out are the average heat transfer rate and the highest radiator effectiveness occur in the Yamacoolant type cooling fluid of 1.992kW and 0.726, the second highest occurs in the Prestone cooling fluid where the heat transfer rate value is 1.918kW and the radiator effectiveness is 0.652, then followed by Seiken where the heat transfer rate is 1.901kW and the radiator effectiveness is 0.634, then followed by DCK the heat transfer rate is 1.702kW and the radiator effectiveness is 0.592 and the smallest is experienced by mineral water where the heat transfer rate is 1.542kW and the radiator effectiveness is 0.501.

Abstract

The tridharma of higher education is the main task and function for every lecturer that must be carried out every semester. One of the activities of the tridharma of higher education is community service which aims to make a scientific contribution owned by each lecturer. On this occasion, the UMA mechanical engineering study program had the opportunity to carry it out in Tanjung Rejo village, Percut Sei District. The master who owns the mangrove forest tourist attraction. The tourist attraction is located on the coast of the Strait of Malacca, where geographically it has the potential for renewable energy, namely wind energy. Based on the measurement data, the average wind speed was obtained 2 m/s. From the potential power that can be generated through a horizontal type wind turbine theoretically 59.8 W. Actually, this turbine has an average power of 20.9 W. This difference occurs due to an efficiency factor of 35%. The potential of wind energy in Tanjung Rejo Tourism Village is very promising for development. This effort will not only increase the energy independence of the village, but also reduce carbon emissions and preserve the environment.

Abstract

Today, especially among industrialized and developing nations, the usage of renewable energy sources is growing in popularity as a means of supplying energy needs. One of the renewable energy sources that is now being heavily exploited in Indonesia is the potential of water that may be used as a source of electrical energy by establishing a hydroelectric power plant (PLTA). One of the turbines that is frequently used in hydropower plants as a part that may transform water's kinetic energy into mechanical energy is the Pelton turbine. There is not a lot of literature on the design of Pelton turbine buckets. In order to determine the most ideal bucket dimensions that can be used with Pelton turbines, this study presents the conceptual and experimental components of the design and analysis of Pelton turbines based on bucket variations. AutoCAD was used to model the bucket and Pelton turbine, and ANSYS Fluent was used to perform the simulation so that results could be analyzed later. By comparing the simulated data of the blade variants 1 and 2, the ideal blade dimension variation is identified by the blade simulation of variant 1. The blade variation 2 with average torque of 5.859 Nm, average angular velocity of 40.822 rad/s, and average power of 242,970 watts is the most ideal blade. With an average torque of 4,735 Nm, an average corner speed of 40,404 rad/s, and an average power of 196,794 W, the blade 3 model has lower values
