Abstract

Waste management in Indonesia is still very undirected and we are still looking for the right solution regarding alternative solutions. One alternative solution for waste management is to manage the waste by turning it into useful items that have selling value. The alternative solution offered is to make brick products made from diapers and plastic packaging waste. This research aims to make 2 products with different compositions, then carry out composition test specimens and test the two brick products through compressive strength tests in the laboratory. After carrying out the process of making bricks with different compositions, a comparative study can be carried out using the One Way ANOVA method and the F count or Critical F result is 4.00687, so F count ≥ F table means that H1 is accepted (Composition A has a significant difference between Composition B). Composition A has a compressive strength test result for concrete bricks that is in accordance with SNI-15-2094-2000, namely 50 Kg/Cm2.

Abstract

Abstract: The demand for electrical energy in Indonesia has experienced a significant surge, becoming indispensable for nearly all modern activities. However, despite this surge, the primary energy source for power plants continues to heavily rely on fossil fuels. Consequently, it is imperative to transition towards renewable energy sources to mitigate environmental impact and tackle the prevailing energy crisis. In response to this need, permanent magnet synchronous generators have emerged as a promising alternative within the electricity industry. These generators operate by utilizing permanent magnets to generate a magnetic field within the coil, thereby eliminating the necessity for excitation current. By leveraging renewable energy sources such as wind or hydro power, these generators strive to optimize electricity production and alleviate the ongoing energy crisis. This research project aims to repurpose materials sourced from used water pump motors, including rotors and stators, to construct permanent magnet synchronous generators. The process involves incorporating permanent magnets into the rotor and modifying the original motor winding. Through rigorous testing involving the application of a 40 Ohm load and varying rotational speeds between 2000 and 1600 rpm, the research reveals that the generator can generate a minimum power output of 0.7 Watts at 200 rpm and a maximum power output of 41.8 Watts at 1600 rpm. The optimal efficiency of 75.78% is attained at 400 rpm. Overall, this research underscores the potential of repurposing existing materials to develop renewable energy solutions, offering a sustainable approach to addressing not only the energy needs of Indonesia but also those of other regions globally.

Abstract

As we enter the 21st century, concerns over dwindling oil and gas reserves have become more pronounced. With energy demand on the rise, particularly in developed nations, projections indicate a 70% increase between 2000 and 2030. By the year 2017, global electricity demand is expected to reach 25.4 trillion kWh. Solar energy emerges as a promising solution, especially in regions like Indonesia, where the entire mainland covers roughly 2 million km2 and receives an average daily radiation distribution of 4.8 kWh/m2. This translates to a solar energy potential of 5.10 mW, equivalent to 112,000 GWp. Technically speaking, solar panels have shown an efficiency improvement of 17.4%. When considering components and the quality absorbed by solar power plants (PLTS) synchronized by KWH EXIM, calculations reveal a performance ratio of 81%, confirming the technical feasibility of implementing such systems

Abstract

Increasing the efficiency of equipment is very necessary to avoid wasting energy. It is known that fossil fuel energy continues to increase and runs out quickly, so alternative energy is needed that can be used continuously and does not run out quickly when used because this energy is easy to obtain and comes from nature. The aim of this research is to create a design for this equipment that can be applied in laboratories, pharmacies, hospitals, etc. The methods used in this design are structural plans and functional plans. In the process of heating the air in the evaporator with varying volumes, namely 1 liter, 2 liters, 2.5 liters, 3 liters and 3.5 liters, you can see a large amount of steam with a short heating process. The results of the research show that it can be seen that the electrical thermal efficiency shows that the smaller the value of the feed water volume, the greater the electrical thermal efficiency (inversely proportional). This shows that one indication is that the performance of the aquadest evaporator saves electrical energy in the heating and evaporation process of optimal water because the less feed, the faster the heating process, and the greater the amount of steam produced in one hour of operation and it can be seen that the energy consumption is spent on a volume of 3.5 liters because the heating time is long compared to other variations in feed water volume so the energy consumption is large

Abstract

The last decade, electric cars have grown so rapidly. One of the driving parts in electric cars is the Brushless DC Motor (BLDC). The use of BLDC motors is needed because this motor has low mechanical losses, this is because the motor does not use brushes. However, in operation, there is still a ripple that is complained by the control or drive of the motor so that the efficiency of the motor rotation output torque and speed is not perfect. One way to operate a BLDC motor is by direct torque control method. The Direct Torque Control method became popular for controlling BLDC motors because it provides a fast dynamic torque response, the variables controlled in this DTC are flux and torque. Direct torque control (DTC) is a method used to control torque and speed on a motor with a variable frequency drive (VFD). This method is a calculation that includes estimating motor flux and torque based on the voltage and current on the stator. In the stator, the flux is estimated based on the stator voltage while the torque is estimated from the stator flux estimator and motor current.The input values measured to the DTC control are the current and voltage of the motor. The torque output of this DTC has a fairly high ripple along with the application of a larger load so that changes in motor load affect ωr. Ripple Torque that affects the speed of the rotor must be given an additional circuit, namely Ripple Suppression. This additional circuit will suppress the ripple so that the torque and speed rotation of the BLDC motor will be better. Therefore, this research will discuss the design and simula tion of the BLDC motor using the direct torque control method with ripple suppression which is expected to produce more efficient output from the BLDC motor due to the torque ripples on the motor have been reduced by the ripple suppression circuit. From the research results, it can be seen that the efficiency of BLDC motors increases by 2 to 3 percent at starting time and increases by around 1.5 percent at steady state.
