Abstract

Sistem catu daya LED menggunakan transformator sebagai penurun tegangan, disamping ukuran fisik dan berat lebih besar juga harganya lebih mahal karena semakin besar kapasitas daya yang dinginkan semakin besar transformator yang diperlukan dan tentunya semakin mahal harganya. Pada disain ini kami menawarkan sebuah catu daya tanpa transformator yang dapat mereduksi harga produksi serta ukuran fisik dan berat piranti. Sistem catu daya tanpa transformator ini menerapkan sistem penurunan tegangan arus bolak balik (AC) menggunakan kapasitor. Sebagaimana diketahui bahwa pada rangkain AC, kapasitor mempunyai reaktansi sebesar XC= 1/(2πfC) Ohm, dimana: f = frekwensi dalam Herzt dan c adalah kapasitas kapasitor dalam Farad. Permasalahan dalam disain ini adalah bagaimana mendapatkan nilai kapasitas kapasitor dan resistor yang optimal sehingga dapat memberikan tegangan yang stabil 12 Volt, untuk dapat melayani arus beban dalam rentang 7 Amper. Metodologi yang digunakan dalam penelitan ini adalah dengan melakukan analisa perhitungan, melakukan simulasi dan pengujian empiris di laboratorium. Berdasarkan perhitungan, simulasi dan pengujian di laboratorium diperoleh nilai kapasitas kapasitor sebesar 9 uF

Abstract

This paper introduces an in-service transmission surveillance and protection-based approach for fiber failures/faults over fiber-to-the-home passive optical network (FTTH-PON) with an excellent combination of Access Control System (ACS) and Smart Access Network Testing, Analyzing and Database (SANTAD). Our hardware design works on a standard local area network (LAN) using a specially designed hardware interfaced with a microcontroller integrated Ethernet to monitor the status of optical signals flow and provide the restoration against fiber failures/faults in FTTH-PON. We also introduce the centralized management and access control program by means of SANTAD. ACS is used to control the troubleshooting mechanism carried out by SANTAD. This design will be implemented at central office (CO) for distant monitoring and remote controlling each optical fiber line's status as well as for detecting any failures/faults that occurs in the network system downwardly from CO towards multiple optical network units (ONUs). The scope of this discussion only highlighted on the monitoring and controlling instead of the restoration scheme.

Abstract

According to the solar insolation map, Indonesia has a daily intensity of solar radiation of 4.8 kW/m per day. The potential of solar radiation is highly exploitable and is the most promising source of energy in the future, the energy generated by the sun is unlimited compared to the increasingly depleting fossil energy sources. Many energy experts are already competing to find new discoveries about environmentally friendly alternative energy sources, one of which is solar cells, although efficiency today still requires further consideration. In this study, the authors used the Wemos module with the ESP 8266 type that can be integrated with the Wi-Fi system as its controller, as well as using a temperature sensor with the DHT11 type to detect the temperature in the room and use the LDR sensor as a light intensity detector or as a lux which can be monitored remotely using an internet connection. Light intensity and temperature monitoring results are obtained with light intensity values and temperature values using the application of the highest value = 1005 lux, the lowest value is = 435 lux. For the highest value of the temperature of = 320 Celsius, for the lowest of = 240 Celsius, in sunlight conditions at peak, the resulting value is the light intensity of 1005 lux and the temperature value of 32 ° Celsius which indicates that the weather conditions are very hot.

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

The commercial use of drones has increased rapidly in this sector in the last few decades, one of which is the Hexacopter Type Unmanned Aerial Vehicle (UAV). Hexacopter is a flying robot without a pilot that can be controlled manually using a remote control and controlled automatically or on autopilot. The advantage of the hexacopter is its ability to maneuver flexibly, it can move in 8 cardinal directions without needing to turn first. However, despite their advantages, certain hexacopters must continue to fly stably under a variety of changing conditions, such as changing weather, different loads, or changing environmental conditions. For this reason, a control system is needed that is able to adapt to these changes. This condition makes it interesting to carry out experimental and simulation studies, namely designing a hexacopter with Model Referene Adaptive Control (MRAC) control. By using a Model Reference Adaptive Control (MRAC) control system with the main control using PID control, the response given is good and optimal, the system parameters reach the values: rise time (ts) 1.0709 s, delay time (td) 0.99 s, peak time (tp ) 2.6600 s, settling time (ts) 3.9351 s, overshoot (mp) 4.0847 and steady state error 0.0001%. The mathematical analysis of the MRAC control system needs to be studied in more depth so that the MRAC control calculations become more accurate.

Abstract

The development of hexacopters has progressed significantly in both hardware and software, leading to increased complexity. Despite these advancements, several challenges remain. The nonlinear, multivariable, and dynamic nature of hexacopter systems often results in flight instability, suboptimal precision in movements, and reduced flight duration. To address these issues, this study proposes the implementation of a fuzzy logic control (FLC) system to enhance the performance and stability of hexacopters during flight. The control system aims to minimize rise time, settling time, and overshoot. The research methodology involves developing a mathematical model of the open-loop system using the System Identification Toolbox in MATLAB, optimizing PID values through the PID Tuner, and designing the fuzzy control system based on error and delta error. The open-loop system demonstrates performance metrics of rise time (Tr) 4.60 s, delay time (Td) 2.76 s, peak time (Tp) 6.50 s, settling time (Ts) 5.91 s, and overshoot (Mp) 1.29%. With PID control, the performance improves to rise time (Tr) 3.24 s, delay time (Td) 1.85 s, peak time (Tp) 10.00 s, settling time (Ts) 9.55 s, and overshoot (Mp) 0%. Furthermore, the fuzzy logic controller achieves superior results with rise time (Tr) 3.19 s, delay time (Td) 1.53 s, peak time (Tp) 4.64 s, settling time (Ts) 3.37 s, and overshoot (Mp) 0%.

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
