Abstract

DC motors are widely used electronic components commonly found in everyday applications. Typically, when a load is applied, a DC motor tends to decelerate and fails to maintain a constant speed. To address this, motor speed can be controlled by adjusting the input voltage. However, to maintain consistent speed under varying loads, a control system is necessary. LQR works by adjusting the motor response to closely approach the desired setpoint, while minimizing both overshoot and undershoot within the system. On the other hand, LQT is a linear control strategy designed to ensure that the system output closely follows a time-varying reference or setpoint. When implemented, LQR yields a motor response that aligns with the target setpoint without any overshoot or undershoot. In contrast, if LQR is not applied, the motor response deviates significantly from the desired target and takes a longer time to settle. Meanwhile, the LQT method produces a quicker response reaching steady state in approximately ±0.5 seconds although it does introduce some overshoot and slight ripple in the signal. Despite these minor drawbacks, LQT is often favored over LQR for applications involving the MG-16B DC motor due to its superior speed in reaching the setpoint.

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

The coast is an area that has potential for tourist attractions, including for turtle conservation which is relied on as a support for the economy. Turtles are one of the protected animals, not just protected by law because they are feared they will become extinct. The Turtle Conservation "Pearl of the Masaran Sea" which is located on Sumbreng Beach, East Java, is one of the turtle conservation areas developed by the Trenggalek Lentera Society. Activities carried out at the turtle conservation site "Pearl of the Masaran Sea" include relocating turtle eggs, caring for turtle eggs, combing eggs, and also releasing hatchlings. There are 5 types of turtles that are protected on Sumbreng beach, some of which are green turtles and hawksbill turtles which are included in the Appendix I category, which means they are prohibited from being traded internationally. Apart from visiting tourists being able to see the turtle breeding process, this conservation also provides economic tourism such as small Jeep facilities that are used to get around the beach and releasing hatchlings in certain months. However, due to lack of exposure to this conservation area. This resulted in a small number of tourists coming, and also some tourists coming in the wrong month and not being able to see the hatchlings being released onto the beach. Therefore, this service presents an innovation in the form of a website facility that is useful for updating all activities taking place at the "Pearl of the Masaran Sea" Turtle Conservation. So it can attract more tourists to visit this tourist attraction and tourists can also find out which months are effective for visiting this tourist attraction. It is hoped that the "Pearl of the Masaran Sea" turtle conservation will have the potential for educational tourism which can be developed further, so that it can support the economy of the surrounding community and can also be used as a source of income for managing the turtle conservation itself.
