Abstract

This research develops a balancing robot control system using a fuzzy logic approach, focusing on the adjustment of membership function parameters. The main components of the system include the ESP32 microcontroller, MPU6050 sensor for detecting tilt angle and angular velocity, and L298 motor driver for DC motor actuation. Triangular-shaped membership functions are implemented, and parameters a, b, and c are adjusted through simulation to enhance system performance. Evaluation results indicate an average settling time of 1.2 seconds, a maximum overshoot of 5%, and a steady-state error of less than 2 degrees. This adjustment successfully balances response speed and stability, providing important guidance for developers in designing a more optimal fuzzy logic control system. The research was conducted at the Electrical Engineering Laboratory of 17 August 1945 University (Untag) Surabaya from June to December 2023.

Abstract

Micro hydro power plants (MHPPs) are increasingly important for decentralized renewable electrification, especially in isolated and rural grids where low inertia makes frequency highly sensitive to abrupt consumer-load variations. The main problem addressed in this study is that governor-turbine dynamics and conventional controller tuning are often insufficient to suppress transient frequency deviation rapidly, while previous MHPP load frequency control (LFC) studies commonly report ICA, BA, SMES, or CES results separately and in per-unit form, making practical comparison less direct. This paper contributes a current benchmark-based synthesis and normalized comparative analysis of Superconducting Magnetic Energy Storage (SMES)-assisted LFC for a 40 kVA, 32 kW, 50 Hz MHPP using the Imperialist Competitive Algorithm (ICA) and the Bat Algorithm (BA) with Integral Time Absolute Error (ITAE) as the optimization objective. Literature benchmark data are reprocessed by converting per-unit overshoot into Hz and by calculating reduction relative to the uncontrolled condition to provide a transparent and reproducible engineering interpretation. ICA-based PID-SMES gives a frequency overshoot of -4.11 x 10^-5 pu (-0.002055 Hz), whereas BA-based SMES-PID gives -4.038 x 10^-5 pu (-0.002019 Hz). Compared with the uncontrolled system, the overshoot reduction reaches 87.07% for ICA and 87.30% for BA. The main contribution of this work is a clarified research-gap map, a normalized ICA-BA comparison on a comparable MHPP benchmark, and a replicable basis for future equal-condition MATLAB/Simulink validation.

Abstract

Autoped has become a popular alternative in environmentally friendly urban transportation. It uses batteries as the main power source to drive their electric motors. However, efficient and optimal battery usage is essential to maintain the performance and durability of autoped. This study aims to design a speed monitoring system for autoped using LiFePO4 batteries by considering variations in user loads. This monitoring system informs autoped drivers about the speed when used and battery usage. This electric autoped is equipped with a DC brushed motor with a specification of 24 Volt/500 Watt. The speed is measured using a metal proximity sensor that functions without direct contact, thus ensuring consistent measurements and reducing the risk of errors due to physical interaction. In addition, a load cell sensor with a maximum weight measurement of 100 kg is used to classify user's weight which is divided into three variations: 35-45 kg, 46-55 kg, and 56-65 kg. As the main energy source, this system uses a LiFePo4 battery with a specification of 24 Volt/36 Ah. The system was tested on a flat track on the campus, where the scooters were used to support environmentally friendly mobility around the campus area. This test ensured that the designed speed monitoring system was able to provide real-time data on scooter performance based on user weight, as well as support increased efficiency of battery energy use.

Abstract

This study aims to explain students' behavior in accessing the kalam.umi.ac.id learning platform and its impact on student academic performance. It analyzes data collected from students' access to the platform during 12 sessions in one semester for the Islamic communication subject taught by Professor Surani. The data includes students' access times, access frequency, and academic performance such as assignment grades, midterm exams, and final exams. Through data processing methods, correlation analysis, and cluster optimization, the study found a positive relationship between access times, midterm exams, final exams, and assignments with students' final grades. The higher these variables, the higher the students' final grades. However, this relationship is not always consistent across different variables. In this study, the Elbow method was used to determine the optimal number of clusters by identifying the point where the variance reduction becomes less significant. Additionally, the Sum of Square Error (SSE) was analyzed to understand the sharp change followed by a gradual decrease in the value of K until stability is reached. Clustering results using the K-Means algorithm showed the presence of three student clusters based on their learning behavior. Cluster 0 is the largest, consisting of 176 students. Cluster 1 has 57 students, and cluster 2 is the smallest with 17 students. These clusters provide insights into varying student learning patterns, including differences in final grades and access frequency. These findings can be used as a basis for developing more effective and personalized learning strategies for students.

Abstract

Kontrol kecepatan turbin memainkan peran krusial dalam menjaga stabilitas dan efisiensi sistem pembangkitan energi. Penelitian ini mengembangkan sistem pengendalian kecepatan turbin menggunakan metode Proportional-Integral-Derivative (PID) berbasis Arduino, dengan proses tuning yang dilakukan melalui pendekatan trial-and-error. Metode ini dipilih karena kemudahannya dalam menyesuaikan parameter Kp, Ki, dan Kd secara bertahap berdasarkan respons sistem terhadap perubahan kecepatan turbin. Tahapan tuning diawali dengan penentuan nilai awal parameter PID, kemudian dilakukan pengujian serta penyesuaian secara bertahap hingga diperoleh kinerja optimal. Evaluasi dilakukan dengan menganalisis karakteristik sistem, termasuk waktu tunda (delay time), waktu naik (rise time), waktu tunak (settling time), overshoot, dan error steady-state. Hasil pengujian menunjukkan bahwa metode tuning trial-and-error memungkinkan sistem mencapai respons yang lebih cepat dengan tingkat kesalahan minimal, meskipun memerlukan waktu serta pengujian berulang untuk memperoleh kestabilan yang diinginkan. Dengan nilai Kd sebesar 0,0005, Kp sebesar 0,04, dan Ki sebesar 0,005, sistem menunjukkan performa yang lebih baik, ditandai dengan overshoot yang lebih kecil serta waktu stabilisasi yang lebih cepat. Pengujian juga mencatat bahwa sistem memiliki rise time sebesar 2 detik, settling time 17 detik, dan overshoot sebesar 115%.

Abstract

Biaya produksi merupakan hal yang harus diperhatikan dalam suatu industri. Biaya produksi tersebut disebabkan salah satunya karena kualitas daya seperti faktor daya dan rugi-rugi daya. Pemakaian beban induktif seperti motor induksi dan tranformator dapat menyebabkan kelebihan pemakaian daya reaktif, dan akan berdampak pada meningkatnya denda PLN yang harus dibayar apabila power factor < 0,85. Hal ini dapat diatasi dengan pemasangan beban yang bersifat kapasitif seperti kapasitor bank untuk menurunkan biaya pemakaian KVAR dan meminimalisir drop tegangan. Tujuan penelitian ini adalah pengoptimalan penggunaan kapasitor bank menggunakan PLC. Stepping otomatis menggunakan cos φ meter sebagai input analog PLC yang akan digunakan untuk penentuan metode yang sesuai dan mengaktifkan kapasitor. Stepping manual dilakukan dengan menekan tombol switch untuk mengaktifkan kapasitor. Hasil dari pengujian, baik stepping manual maupun otomatis sesuai dengan program PLC dan display. Metode sudah dapat bekerja secara otomatis dan penentuan akan sesuai dengan kombinasi kapasitor. Dengan hasil cos φ pada motor 1 yang awalnya sebesar 0,56 menjadi naik sebesar 0,86, pada motor 2 nilai cos φ yang awalnya sebesar 0,74 menjadi naik sebesar 0,93, pada motor 3 nilai cos φ yang awalnya sebesar 0,6 menjadi naik sebesar 0,97 dan pada motor 4 nilai cos φ yang awalnya sebesar 0,65 menjadi naik sebesar 0,95

Abstract

Garbage is one of the problems that we often encounter in the community. One of the factors causing the accumulation of garbage is the lack of public awareness to dispose of garbage in its place. In this problem, it is necessary to have a smart trash can using sound information media which includes Ultrasonic Sensors as distance detectors and trash volume detectors, Servos are used to control the trash can cover, Speakers are used as information media, DFPlayer mini is used as a voice recorder and microcontrollers are used as input data processors from the components used. The trash can cover will open and close automatically by detecting humans at a distance of ≤ 30 cm then detecting the height of the trash from the trash can cover ≤ 10 cm then the trash can is full then the trash can cover will not open and emit information in the form of sound. The method used in this study is the experimental method, namely by designing, assembling, and testing a smart trash can system based on Arduino Uno. Testing was conducted to evaluate the performance of the sensor, and the voice module in responding to the presence of objects in front of the trash can. This research is useful for the community because it can increase awareness in disposing of garbage in its place through an interactive approach in the form of sound, thus supporting the creation of a cleaner and more orderly environment. In addition, scientifically, this research contributes to the development of science and technology, especially in the field of hardware that can be used as a basis for similar innovations in various fields of life.

Abstract

Electricity is a basic need for almost all Indonesian people. Electricity itself is the main requirement in all economic activities and daily activities, while the availability of fossil fuels for power plants in nature is decreasing, so it requires alternative energy sources that can meet energy needs in the form of solar panels as electricity generators. In this research, a micro-scale solar power generator has been developed for the purpose of lighting the prayer room terrace. In the use of solar panels themselves, it is still static, which results in the utilization of solar energy so far being less than optimal. To optimize solar energy as an electrical energy source, solar panels are an alternative. In this study, the design of a 20WP solar panel uses an automatic timer motor based on the real-time principle, as a driver using a servo motor. From the results of testing the timer motor and without using this timer motor, the voltage produced is different, for those using an automatic timer motor the result is 16.48 Volts, while without using an automatic timer motor the voltage produced is 14.94 Volts and for the efficiency of energy conversion from each method has a different value, namely the value of the satis panel is 48% while the value of the dynamic panel is 52%. So from the results, the highest conversion efficiency was obtained at 52%. The results of the study showed that the greater the conversion efficiency, the greater the voltage produced.
