Abstract

Semakin berkembangnya jaringan komunikasi mengakibatkan meninggkatnya pengguna jaringan komunikasi jaringan berbasis seluler. Untuk mengoptimalkan kualitas jaringan di dalam coverage area suatu BTS digunakan teknik tilt pada antena sektoral. Salah satu BTS yang dilakukan optimasi bernama 4115874E_TEKAM MEPAWAH yang berada di jalan Tj.Harapan, Kota Pontianak Kalimantan Barat. Pada penelitian ini dilakukan untuk mengetahui pengaruh dari tilt antena sektoral terhadap kualitas jaringan dengan parameter RSRP yang diterima di dalam coverage area antena sektoral tersebut. Pengambilan data dilakukan di lokasi penelitian dan simulasi menggunakan ATOLL 3.4 dengan menggunakan metode tilting dan drive test. Perubahan tilt antena yang terjadi pada sektor 2 dan sektor 4 dari 3° ke 2° pada mechanical tilt. Pada saat mechanical tilt 2° di lokasi penelitian diperoleh persentase kualitas jaringan RSRP pada -70 sd. -80 dBm sebesar 0,29%, pada -80 sd. -90 dBm sebesar 9,80%, pada -90 sd. -100 dBm sebesar 31,12%, pada -100 sd. -110 dBm sebesar 52,74%, dan -110 sd. -120 dBm sebesar 6,05%. Sedangkan pada saat simulasi mechanical tilt 2° diperoleh persentase kualitas jaringan RSRP pada -60 sd. -70 dBm sebesar 0,7%, pada -70 sd. -80 dBm sebesar 0,7%, pada -80 sd. -90 dBm sebesar 11,27%, pada -90 sd. -100 dBm sebesar 16,20%, -100 sd. -110 dBm sebesar 53,52% dan -110 sd. -120 dBm sebesar 17,61%. Kemudian mechanical tilt pada sektor 2 dan sektor 4 dirancang kembali menggunakan ATOLL 3.4 secara bervariasi dengan tilt berkisar antara 2°, 3° dan 4° yang belum diterapkan di lapangan dan simulasi untuk memperkirakan persentase kualitas jaringan RSRP yang akan diterima di lapangan, dari new palnning mechanical tilt ini diperoleh rancangan terbaik pada saat sektor 2 mechanical tilt 4° dan sektor 4 mechanical tilt 2° karena memiliki persentase parameter RSRP terbaik dari rancangan tilt antean yang lainnya yaitu pada parameter RSRP -90 sd. -100 dBm dengan nilai 27,60%, -100 sd. 110 dBm 62,45% dan -110 sd. 120 dBm sebesar 0,75%.

Abstract

This study focuses on the development of an interactive web-based learning platform for Proportional-Integral-Derivative (PID) control systems, aimed at addressing the conceptual challenges faced by electrical engineering students when learning PID through conventional teaching methods. Despite its foundational role in control theory, PID remains difficult to grasp without practical visualization and hands-on experimentation. To bridge this gap, the research introduces a practical and accessible platform that enhances conceptual understanding through real-time simulations and physical interaction. The proposed system integrates key hardware components including an ESP-32 microcontroller, DC motor, rotary encoder, BTS 7960 motor driver, and I2C LCD. The platform’s web interface is built using HTML, Tailwind CSS, and JavaScript, enabling intuitive user interaction. Motor response data is captured via the ESP-32 and transmitted to the web interface using the WebSocket protocol, allowing users to instantly visualize system behavior as PID parameters (Kp, Ki, Kd) are adjusted. This dynamic feedback mechanism enables students to observe changes in system characteristics such as rise time, overshoot, and settling time in real time. To evaluate the platform’s feasibility, practicality, and educational effectiveness, beta testing was conducted among electrical engineering students using Likert-scale questionnaires. The results demonstrated that users were able to successfully interpret the impact of PID tuning on system performance. The average evaluation score reached 75.13%, indicating strong agreement regarding the platform’s educational value and its effectiveness in enhancing learning outcomes. In conclusion, the study affirms that the developed web-based platform offers a feasible, engaging, and pedagogically effective alternative to traditional learning approaches. By combining interactive simulations with physical experimentation, the platform significantly improves students’ understanding of PID control systems.
