Abstract

Piezoelectric is one of the generators of electrical energy when the material is deflected due to pressure. Research has been done on the potential of the fins on the electric voltage produced by piezoelectric. The research method used is to observe the piezoelectric vibrating due to the flow of air passing through the bluff body resulting in a deflection of the fins to strike the piezoelectric and measuring the electric voltage. Changes in the speed of fins installed with piezoelectric dimensions, namely fin one length 12 cm and width 10 cm, fin two length 12 cm width 10 cm and tip width 12 cm, fin three length 12 cm, width 10 cm and tip width 14 cm. The research was conducted in a mini wind tunnel with wind speeds of 5 m/s, 7 m/s, and 9 m/s with a piezoelectric distance to the rhombus bluff body is 80 mm. The results obtained are fin 1 with a speed of 9 m/s produces an electric voltage of 5.15 volts, fin 3 with a speed of 9 m/s produces an electric voltage of 5.46 volts, and fin 4 with a wind speed of 9 m/s has the highest voltage value, namely 5.58 volts. The airflow as it passes through the end of the bluff body section causes the fin to move up and down. The greater the turbulence that occurs, the greater the air hitting the piezoelectric surface so that the value of the electric voltage becomes high.

Abstract

Currently, buildings are responsible for 32% of the world’s energy consumption, with the most massive energy-consuming device in facilities being the refrigeration system. Photovoltaic is an alternative source of energy without causing environmental damage. Solar Refrigeration is an attractive solution because when there is much solar radiation, peak thermal energy is generated, and a lot of cooling capacity is needed. In this research, the amount of PV modules used as the LiBr-H2O Absorption Refrigeration System’s primary energy source is investigated. PV modules have a dual function, namely as a producer of electric power and producing thermal waste, both of which can be used as energy sources to drive this refrigeration system. In this thermal waste, two thermal sources, namely thermal convection and thermal radiation, accumulate to activate heat exchange at the LiBr-H2O absorption refrigeration system’s generator side. For electrical power from the PV module, it is used to run the air heater to increase the temperature until it reaches the optimum point for hot water supply between 65 to 70 oC. The results are that at least 100 modules of 100Wp Monocrystalline PV Module are needed to drive the LiBr-H2O absorption refrigeration system. Still, it is limited to 15.00, after which the energy source is switched back to electricity from PLN because, after 15.00, many PV modules are required and takes up a large enough space.

Abstract

The choice of fuel (fuel oil) whose price is higher needs a solution, especially for conventional foundry entrepreneurs. We need alternative energy that is cheap and easy to get. Wood pellets are an attempt to replace fuel with cheap fuel. As with previous studies, the main objective of this study was to measure the energy potential of the smelting furnace flue gas. The analysis results show that 365,413.3 kJ of heat energy is wasted from the total point required for smelting. The flames sometimes coming out of the furnace flue gas channel indicate that some heat energy is smashed into the free air. The exhaust gas temperature is measured at 500-550⁰C, and you can see flashes of fire coming out frequently. This indicates that there is energy potential for the working process of the pyrolysis reactor; apart from that, the moments of fire that often appear indicate an excess of the combustion process in the furnace. This study's results may differ from other smelting furnace constructions and conditions.

Abstract

The need for electricity in Indonesia continues to increase every year and its supply is increasingly limited because most power plants in Indonesia still depend on conventional energy (fossil fuels). Solar power plants (PLTS) are very suitable to be developed in Indonesia because they have abundant sources of solar energy. with an average solar radiation intensity of about 4.8 kWh/m² per day. Therefore, in this study a design of a household-scale solar power plant (Solar Home System) will be made, with the aim of saving electricity and electricity bills from PLN. The power designed in this study is 0.9 kW. Using 3 units of ST Solar 300 Wp solar panels and the Solis On-Grid Mini-1000-4G Inverter. Based on the economic analysis, this design requires an initial capital of Rp. 17,500,000. savings in electricity bills obtained each month is IDR 154,464. and from the results of the BEP calculations that have been carried out, it is known that the capital will return in the 9th month-6th year

Abstract

The waste discarded by the community every day comes from agricultural activities, markets, households, entertainment, and industry. One form of waste is domestic waste, which originates from household waste. The increase in domestic waste goes hand in hand with the development of physical infrastructure and the expansion of adequate facilities and infrastructure. As a result of this pollution, environmental balance is disrupted. In this experiment, one method will be used to reduce or minimize environmental pollution, especially air pollution, by using an electrostatic precipitator as a tool to capture solid particles from exhaust gas in waste combustion smoke. It is expected to efficiently reduce the solid particle content in the exhaust gas from waste combustion. The electrostatic precipitator is an alternative for reducing environmental pollution, as it has high efficiency, reaching 98.4%, and can capture particles as small as 100 micrometers. The electrostatic precipitator works by capturing solid particles that pass through the particle charging area, which is at a high potential. The charging area provides high-speed electrons by ionizing molecules and particles in the exhaust gas from the smoke. The exhaust gas particles receive positive ions and become highly charged, allowing them to be attracted and captured by negatively charged electrodes (collecting plate). Through this process, the solid particle content in the exhaust gas from waste combustion can be eliminated. Therefore, this final project involves the development of an electrostatic precipitator prototype aimed at reducing environmental pollution, particularly air pollution.

Abstract

Engine performance refers to the capability of an internal combustion engine to convert input energy, specifically fuel, into useful power. One method to enhance engine performance is to modify components of the intake system that affect airflow. A turbo insulator, which is a modified gasket connecting the carburetor to the intake manifold, is designed to generate turbulent airflow into the combustion chamber, thus improving combustion efficiency. This study aims to design and evaluate a turbo insulator on the intake manifold of a Suzuki Shogun NR-125 CC motorcycle through experimental testing of its impact on engine performance—specifically torque and power. A descriptive analysis method was employed for data analysis. Engine performance testing was conducted using an engine dynamometer, following ISO 1585 standards, within an engine speed range of 3,000 to 9,000 rpm, under standard factory conditions and with various turbo insulator configurations (5 and 7 blades, 45° and 60° blade angles, 4 mm and 8 mm thicknesses). The results indicate that the turbo insulator improves engine performance. The most optimal configuration, V-5 (5 blades, 45° angle, 8 mm thickness), achieved a maximum torque of 11.27 Nm at 3,500 rpm and a maximum power output of 10 HP at 7,750

Abstract

The performance of vortex turbines in ultra-low-head hydropower plants is crucial for harnessing energy in irrigation channels and small rivers. Therefore, an optimal design is needed to maximize the conversion of flow energy into electrical power. This study aims to evaluate and determine the best-performing configuration of ultra-low-head vortex turbines. The method used is Computational Fluid Dynamics (CFD) simulations employing the k-ω Standard turbulence model, with variations in the number of blades (3, 5, and 7) and a fixed blade angle of 15°. The results show that the 7-blade configuration with a 15° angle provides superior performance, generating 3.90 W of power, reducing NPSH by 2%, and increasing force by 6%, with a force value of 52.65 N. The implications of these findings suggest that the 7-blade–15° configuration is a suitable design reference for optimizing ultra-low-head vortex turbines in micro-scale hydroelectric power plants, supporting the utilization of renewable energy in irrigation networks and rural areas.

Abstract

Automated Guided Vehicles (AGVs) are a smart transportation solution that is increasingly being used in industry. The stability and strength of the chassis are critical factors in ensuring AGV performance when carrying loads. This study examines the effects of load variations and material types on the structural performance of AGV chassis through an experimental approach and numerical simulation based on Finite Element Analysis (FEA). The materials used were ASTM A36 and ASTM A500, with loads of 5 kg, 10 kg, and 15 kg. A chassis design with dimensions of 400 × 300 × 80 mm was modeled and analyzed using Computational Fluid Dynamics (CFD) software. Validation was performed through experimental testing using a dial indicator. The results show that at a 15 kg load, ASTM A500 experienced a maximum stress of 60.15 MPa and a deflection of 0.00078 m, lower than ASTM A36, which reached 68.06 MPa and a deflection of 0.00089 m. The difference between the simulation and experimental results was well below 10%. Similarly, regarding the safety factor, ASTM A500 has a value of 2.7145 at maximum load, indicating that this material has a higher safety margin compared to ASTM A36. Based on these results, ASTM A500 is considered more efficient and stable, and is more recommended for AGV chassis applications. This study highlights the importance of integrating numerical and experimental methods to produce optimal structural designs.
