Abstract

The presence of wild monkeys in the Engineering Prayer Room at Malikussaleh University has become a severe problem for cleanliness and worship activities. Monkeys often damage equipment and disturb the comfort of pilgrims, causing material losses and threatening environmental cleanliness. Traditional methods to repel monkeys have proven ineffective for a long time, so technological solutions such as ultrasonic waves are needed. This study looked at the effects of using various ultrasonic frequencies on monkeys at multiple distances to determine their effective range of distraction. The results show higher frequencies cause more significant interference, especially at close range. At 23 kHz and 26 kHz, monkeys were only disturbed at a distance of 1 and 2 meters, without disturbance at 3 and 4 meters. The frequencies 29 kHz and 32 kHz show interference at a distance of 1 and 2 meters, with variations at 29 kHz at 3 meters. At 35 kHz, the monkeys were highly disturbed at 1 meter, disturbed at 2 meters, and slightly disturbed at 3 and 4 meters. The 38 kHz and 41 kHz frequencies cause significant interference at 1 and 2 meters, and interference is still felt at 3 and 4 meters. Thus, using frequencies above 30 kHz has proven effective in driving away monkeys up to a distance of 4 meters, with the highest intensity of interference at a distance of 1 to 2 meters. It is hoped that using ultrasonic technology can maintain cleanliness, safety, and comfort in prayer activities in prayer rooms and demonstrate commitment to sustainable and environmentally friendly solutions.

Abstract

Pressure sensors play a crucial role in various industrial and scientific applications. The accuracy and precision of pressure measurements depend highly on the sensors' calibration. This study aims to calibrate the HK1100C pressure sensor using a linear regression method, supported by the Arduino IDE software, and to display real-time measurement results via an I2C LCD screen. The experimental procedure involves connecting the HK1100C sensor to an Arduino UNO board, collecting pressure data using a pressure gauge as a reference, and analyzing the data through linear regression to obtain the calibration equation. The results indicate that the HK1100C sensor provides high accuracy and precision. The smallest average error was recorded at 10 PSI with a value of 0.00038%, while the most significant average error occurred at 2 PSI with a value of 0.00372%. Additionally, the standard deviation of the measurements was relatively low, indicating good data consistency. The lowest standard deviation was found at 6 PSI at 0.0012%, and the highest at 12 PSI at 0.092%. The linear regression method effectively calibrated the HK1100C sensor, resulting in accurate and consistent pressure measurements. This approach also demonstrates that the Arduino IDE is an efficient and flexible tool for developing pressure measurement systems tailored to specific needs.

Abstract

Electrical energy is an important part of supporting life. PLN, as the main source of electricity supply, does not guarantee that it will always be reliable, so alternative resources are needed to support these electricity needs; the resources required to replace PLN's main resource are generators. The automatic main failure is equipment with an automatic control system to overcome main channel disturbances of the electric energy supply system and generator heating system. To extend the genset life in the input section, a push button is a conventional control on the automatic main failure circuit, which includes starting the generator, the generator off, and resetting. In the process section, the Outseal PLC Mega V1 functions as a data or command processor from input to output. From the test, it can be concluded that the time needed to activate the generator when the PLN goes out is ± 15 seconds if the generator can be activated by starting once. The fuel indication system also works according to its function. From the results of the generator heating system scheduled for automatic main failure, the time that has been programmed is 1 time in 7 days for ± 45 minutes

Abstract

Pertanian adalah sektor yang sangat vital bagi kehidupan masyarakat pedesaan di Indonesia, termasuk di Kecamatan Glumpang Tujuh, Lhoksukon, Aceh Utara. Meskipun tanahnya subur, pengelolaan irigasi di daerah ini masih mengandalkan sistem tradisional yang kurang efisien, menyebabkan pemborosan air, ketidakstabilan hasil pertanian, dan peningkatan biaya. Dengan adanya tantangan ini, penerapan teknologi Internet of Things (IoT) dalam sistem irigasi otomatis diharapkan dapat menjadi solusi untuk meningkatkan efisiensi penggunaan air dan produktivitas pertanian. Teknologi ini menggunakan sensor kelembaban tanah yang dapat mendeteksi kondisi tanah secara real-time dan mengatur aliran air sesuai kebutuhan tanaman. Sistem irigasi otomatis berbasis IoT dapat mengurangi pemborosan air, menghemat biaya, serta meningkatkan hasil pertanian secara berkelanjutan. Program pengabdian masyarakat yang dilakukan di Glumpang Tujuh melibatkan edukasi dan pelatihan kepada petani tentang penggunaan teknologi ini. Hasil dari penerapan teknologi ini diharapkan dapat mendukung pertanian yang lebih efisien dan ramah lingkungan. Keberhasilan program ini tidak hanya bergantung pada penerapan teknologi, tetapi juga pada keberlanjutan dan partisipasi aktif dari masyarakat, pemerintah, serta pendampingan berkelanjutan untuk memastikan manfaat jangka panjang.

Abstract

The development of technology in the 4.0 era has led to the creation of various smart devices that can ease household chores, including in the field of cleaning. This rapid innovation brings significant changes such as vacuuming robots. A vacuuming robot is an innovative design to solve cleaning automatically. This research aims to design a vacuuming robot using Takagi-Sugeno fuzzy navigation and holonomic movement mapping. This innovation in the field of automation is designed to improve efficiency and accuracy in the cleaning process. This system integrates several main components: Arduino Mega 2560 as the central controller, DSM501A dust sensor for detecting dust levels with a range of 20-150 μg/m³, and HC-SR04 ultrasonic sensor for obstacle avoidance at a distance of 5 60 cm. The drive system uses an L298N motor driver to control the mecanum wheel with a PWM value of 150-250, enabling precise holonomic motion with a position error of 1.2% to 4.1%. The robot can move at a speed of 0.5 m/s in the no-obstacle condition and adjusts to 0.3 m/s when detecting obstacles, with a system response time of 1.5 seconds. Test results showed consistent performance, with maximum speed reaching 873.2 RPM without load and 714.4 RPM with load at PWM 250, while in holonomic motion testing, the robot demonstrated high accuracy in diagonal motion and 360° rotation with a position standard deviation of only 0.7 - 1.5 cm. The Takagi-Sugeno fuzzy system successfully classified the obstacle distance into three categories (near, medium, far) and regulated the motor speed between 350-1100 RPM according to the environmental conditions, proving that the integration between TakagiSugeno fuzzy algorithm and holonomic design resulted in an efficient and adaptive vacuum robot system, capable of effective navigation and cleaning while maintaining high precision in obstacle avoidance.

Abstract

The PT100 temperature sensor, a type RTD (resistance temperature detector), is widely employed in industries, particularly for steam boiler temperature regulation. Precise temperature measurement is vital for operational efficiency and safety maintenance. Utilizing linear regression for calibrating and measuring temperature with the PT100 sensor integrated with Arduino Uno and LCD I2C is proposed to enhance accuracy. Testing involved assembling the PT100 sensor with Arduino Uno and LCD I2C. Test data were employed for linear regression to derive the calibration equation. Measurements were conducted by comparing PT100 sensor readings with a digital thermometer across a temperature range of 30ºC to 75ºC at 5ºC intervals, with each temperature point tested five times. Results exhibit good accuracy in temperature measurement with the PT100 sensor, featuring low error and percentage error. The standard deviation indicates consistent measurement. Integration of the PT100 temperature sensor with Arduino Uno and LCD I2C, coupled with linear regression for calibration, yields a precise temperature measurement system. Testing against a digital thermometer demonstrates highly accurate outcomes. This developed system finds application in high-precision temperature measurement for steam boiler operations.
