Abstract

Di dalam sebuah sistem perlu adanya perancangan sebuah sistem pengendali yang baik untuk mendapatkan nilai keluaran (output) atau hasil yang diinginkan. Motor DC adalah motor arus searah yang mengubah energi listrik menjadi energi mekanik. Motor DC sering digunakan karena kontrol kecepatan yang presisi dalam dunia industri. Di dalam sebuah sistem pengendalian motor DC dibutuhkan komponen seperti sensor dan controller. Controller merupakan sebuah pengendali yang akan memberikan sinyal keluaran berupa sinyal kontrol yang akan dikirimkan ke dalam plant atau sistem yang dikontrol. Pada sistem pengendalian tertutup terdapat adanya nilai feedback yang dibaca oleh sensor dan dikirimkan kembali ke controller sebagai nilai error. Nilai error ini yang nantinya akan mempengaruhi nilai sinyal kontrol dan akan berdampak pada nilai keluaran dari sebuah sistem atau plant. Untuk memperoleh sistem yang stabil maka respon sistem harus mencapai fase steady state. Dalam penelitian ini, sistem akan di simulasikan sedemikian rupa dengan menggunakan program Matlab dengan sistem kendali linear quadratic regulator. Pemilihan sistem kendali ini diharapkan mampu memberikan respon yang stabil. Berdasarkan penelitian yang dilakukan simulasi plant dengan sistem kendali LQR PID mempunyai nilai settling time 2.5 sekon dan rise time 2 sekon. Sedangkan plant dengan sistem kendali LQR mempunyai settling time dengan waktu 1.1 sekon dan rise time 1.05 sekon. Meskipun plant dengan sistem kendali LQR memiliki settling time dan rise time lebih cepat tetapi respon yang dihasilkan lebih stabil menggunakan sistem kendali LQR PID. Pada sistem LQR respon setelah mencapai steady state cenderung lebih tinggi daripada setpoint.Kata kunci— Motor DC, LQR, PID, Matlab

Abstract

This study examines the application of Fuzzy Logic Controller (FLC) to optimize the performance of Direct Current (DC) motors. DC motors offer advantages such as high starting torque and ease of maintenance, making them suitable to replace oil-fueled engines that contribute to pollution and global warming. The transition to electric vehicles is supported by advances in battery technology, which provides reliable DC electricity. An important aspect of using DC motors in vehicles is speed control, which is essential for optimizing performance. FLC provides an alternative by using fuzzy rules for decision making, improving stability, accuracy, and dynamic response under various conditions. This study aims to determine the optimal control parameters for DC motors using FLC. The results showed that the rise time was around 1.05 seconds and the settling time was around 1.1 seconds. Simulations performed in Simulink Matlab showed that FLC allows the system to reach the desired point with minimal overshoot.

Abstract

This research presents the design and implementation of an automatic lamp control system using a photodiode sensor and an IC UA741 comparator circuit. The aim is to develop a system capable of responding to changes in light intensity in real-time to control the ON/OFF state of the lamp. The method involves designing a light detection circuit with a photodiode, signal conditioning, and voltage comparison using the UA741 comparator. Experimental results show that the output voltage of the photodiode is directly proportional to the incident light intensity. During testing, a maximum voltage of 3.6 V was recorded when the photodiode was exposed to light from 5 LEDs, with the voltage decreasing as the number of light sources was reduced. The system successfully switches the lamp on automatically when the light intensity falls below a defined threshold and switches it off when the light exceeds this threshold. This design offers an energy-efficient lighting control system with simple architecture, low cost, and high responsiveness, making it suitable for household applications or small public areas.

Abstract

Breast milk is the main source of nutrition for infants and is highly susceptible to spoilage if not stored at the right temperature. This system uses temperature sensors to monitor the thermal conditions in the storage cabin and automatically control the cooling fan to maintain the ideal temperature for breast milk storage. Test results show that the thermoelectric-based cooling system works optimally in conditions without products, with an initial temperature of 31.3°C that decreases to 2.3°C within 70 minutes. However, in conditions with breast milk products, the initial temperature of 35.3°C could only be reduced to 5.4°C within 120 minutes. This difference indicates that the presence of the product provides an additional thermal load that slows down the cooling process. Therefore, a responsive automatic temperature control system and better thermal insulation are needed to maintain the breast milk storage temperature stably around 4°C. This system is expected to maintain the quality of breast milk during storage and support users' needs in maintaining stable storage temperature efficiently.

Abstract

This project was developed to create an automatic system that can control a lamp based on the surrounding light conditions. The system uses an LDR (Light Dependent Resistor) sensor to detect light intensity and an LM324 IC as a comparator to determine when the lamp should turn on or off. When the ambient light decreases (such as during nighttime), the resistance of the LDR changes and sends a signal to the LM324 circuit. The main purpose of this system is to enable the lamp to automatically turn on when it gets dark and turn off when it becomes bright again, without the need for manual switching. In this way, the system helps to save electrical energy and improve lighting efficiency, especially in areas that are often forgotten to be turned off, such as porches or garden lights. Based on the testing results, the system functions properly and responds quickly to changes in light. The circuit is also stable and easy to build, as it uses simple and commonly available components. Overall, this system is suitable for various lighting automation purposes in residential areas as well as public spaces.

Abstract

Water is one of the basic needs that must be met by humans. To meet drinking needs in urban areas, the easiest and cheapest way for people is to buy refilled drinking water. However, the process of filling drinking water is still done manually by humans, so it is prone to errors. Therefore, in this study, the automation of gallon water filling will be carried out using Outseal PLC. Outseal PLC is used because of its relatively low price and greater reliability when compared to a microcontroller. In addition, the gallon filling status will also be displayed on the HMI display. In this study, a trial will be conducted on a drinking water installation at the Indramayu State Polytechnic (Polindra). Before testing, the flow sensor used must be calibrated first. Calibration is done by comparing the results of the flow sensor readings with the PDAM water meter to obtain a conversion of pulses to liters of water. Based on the tests that have been carried out, the results obtained are that the system can work well, namely the valve and pump turn on when the start button is pressed and will automatically turn off when the sensor has read a water volume of 19 liters. However, the sensor shows different readings when the water source used has a different water flow rate. In the first calibration using PDAM water flow rate, a pulse value of 464 was obtained for 1 liter of water, while in the second calibration using pump water flow rate, a pulse value of 566 was obtained for 1 liter of water. This is caused by the sensor used having less sensitivity to changes in water flow rate, which results in different reading results for different water flow rate. Therefore, the sensor must be recalibrated if it is to be used in water installations with different water flow rate. Although the sensor reading values are inconsistent, from tests carried out 40 times, the difference in readings is less than 10%.
