Abstract

Penerangan Jalan Umum (PJU) merupakan fasilitas penting yang membutuhkan solusi efisien dan berkelanjutan. Penelitian ini mengembangkan sistem PJU berbasis energi hybrid (PLTS dan PLTB) menggunakan Internet of Things (IoT) untuk meningkatkan efisiensi dan stabilitas energi. Sistem ini memonitor dan mencatat output energi secara otomatis, memungkinkan pengawasan jarak jauh melalui aplikasi Blynk. Penelitian dilakukan di Kampus 2 Institut Teknologi Padang (ITP) menggunakan metode kuantitatif dengan pengukuran harian output energi. Hasil menunjukkan daya tertinggi PLTS berdasarkan sensor adalah 65,39 Watt, dan alat ukur mencatat 68,13 Watt pada 27 Agustus 2024. Turbin angin menghasilkan daya tertinggi 3,78 Watt (sensor) dan 3,99 Watt (alat ukur) pada hari yang sama. Kesimpulannya, sistem PJU hybrid berbasis IoT mampu mendukung pemanfaatan energi terbarukan secara efisien dan optimal.

Abstract

As a result of a decrease in the mass flow rate at the inlet section of a variable refrigerant flow (VRF) cooling system, the refrigerant flow system performs poorly. To increase efficiency the steam injection cycle method is used. The effects of steam injection are theoretically explored in this study over a wide range of medium pressures and ambient temperatures, and the findings are supported by experimental data. Compressor heating capacity, input power, coefficient of performance (COP), and isentropic efficiency are all affected by pressure. At low ambient temperatures, the increase in COP by steam injection is remarkable. In this study, the performance of the cooling system with the injection cycle was evaluated, the system with this injection cycle resulted in an increase in cooling capacity of 3.26% and an energy efficiency ratio (EER) of 2.32%.

Abstract

This research is motivated by the current fact that the availability of energy sources on the earth continues to increase and the demand for energy continues to increase in line with the increasing demand for energy on earth. population growth. So the use of new renewable energy sources and environmentally sound is needed. This study aims to determine the voltage generated using used battery carbon electrodes and copper, the effect of used battery carbon electrodes and single copper wire on the resulting voltage and the effect of salt content on the resulting voltage capacity. From the research results, it is obtained that the carbon electrodes of used batteries and copper can generate voltage using a solution of salt water and sea water. The highest voltage in the salt water solution is 1965mV and the lowest voltage is 405mV. In seawater solution, the highest voltage is 2071mV and the lowest voltage is 1890mV. The effect of the electrode on the resulting voltage is whether or not the entire surface of the electrode is immersed so that it affects the resulting voltage. And the effect of salt content on the resulting stress is 10%, 5%, 3%, 2% and 37%. With successive voltages of 740mV, 1777mV, 1965mV, 1920mV and 2071mV. With this it can be concluded that the use of used battery carbon electrodes and single copper wire as a substitute for electrodes in generating voltage using an electrolyte solution of salt water and sea water can be used as an alternative energy source. Keywords: Salt Water, Alternative Energy, Used Carbon Electrodes, Copper Electrodes , Electrochemistry

Abstract

The primary aim of this paper is to offer key insights into solar energy and waste heat adsorption cooling systems, as well as to present a helpful approach concerning the design aspects of the adsorbent bed utilized in adsorption cooling. In recent decades, solar-powered water purifiers have primarily been utilized for heating water in residential settings. In contrast, solar cooling systems have mainly been designed for demonstration purposes. It indicates that absorption cooling systems are better suited for large buildings, while adsorption cooling systems show greater promise for smaller air conditioning units. It is advised to plan solar-powered systems in public facilities. Highly efficient heat pumps are regarded as the best supplementary heat providers since they can operate independently of weather conditions.

Abstract

This study aims to develop and analyze the performance of a hexacopter control system used in weather modification technology missions. Several control methods are applied, including PID, Fuzzy Mamdani, Fuzzy Sugeno, and Model Reference Adaptive Control (MRAC). The tests are conducted through simulations in MATLAB Simulink and Mission Planner, using step response parameters such as delay time, rise time, peak time, settling time, overshoot, and steady-state error as performance benchmarks. The results indicate that MRAC provides the most balanced performance in terms of speed and accuracy, Fuzzy Sugeno excels in response speed, while PID and Fuzzy Mamdani offer high stability.

Abstract

In the Hexacopter flight control system, there are three very influential movements, namely Pitch, Roll and Yaw movements. Roll movement is very important to note because it affects the direction of the plane's flight. This movement is strongly influenced by the system's dynamic response to changes in hardware characteristics and the influence of changes in wind direction and speed from external systems. For this reason, this research is offered to implement a control system that can adapt to these dynamic disturbances. This study proposes the application of a proportional integral derivative (PID) control system, where constant values can adjust to dynamic changes in the system. These constant values can adjust to changes in errors and delta errors at any time. then a fuzzy logic controller (FLC) algorithm is applied, to make the constant values adaptable. The design of Fuzzification and Defuzzification is based on the maximum error and delta error limits. After real-plant testing, system performance is obtained as follows: settling time = 24mS; peak time 21mS; rise time = 9mS; delay time = 4.4mS; percent overshoot and steady state error = 1%.

Abstract

VRV systems are multi-split HVAC systems that maintain different portions by varying refrigerant volume. These systems control refrigerant volume for efficiency and dependability. This review aims to identify VRV system elements affecting operational and performance factors. Previous studies are crucial for future large-scale VRV development.
