Abstract
Grounding rod merupakan komponen penting dalam sistem perlindungan petir, yang berfungsi untuk menyalurkan arus petir ke dalam tanah secara efektif. Resistivitas tanah dan kedalaman pemasangan grounding rod merupakan parameter kritis yang mempengaruhi kinerja grounding rod. Oleh karena itu, penelitian ini bertujuan untuk menentukan dimensi optimal grounding rod yang dapat meminimalkan resistansi grounding serta mempertimbangkan dari segi harga bahan grounding rod. Metode optimisasi yang digunakan dalam penelitian ini adalah Monte Carlo dan Particle Swarm Optimization (PSO) untuk tujuan perbandingan. Metode Monte Carlo digunakan dalam simulasi menggunakan perangkat lunak COMSOL untuk mengevaluasi variasi resistivitas dan kedalaman tanah terhadap performa grounding rod. Simulasi ini menghasilkan data yang kemudian dianalisis menggunakan metode PSO pada MATLAB untuk menemukan dimensi optimal grounding rod yang menghasilkan resistansi grounding minimal. Hasil dari kedua metode optimisasi tersebut kemudian dibandingkan untuk mengevaluasi efektivitas dan efisiensi masing-masing metode. Hasil penelitian menunjukkan bahwa baik metode Monte Carlo maupun PSO dapat mengidentifikasi dimensi optimal grounding rod dengan mempertimbangkan variasi resistivitas dan kedalaman tanah. Namun, perbandingan kedua metode ini menunjukkan adanya perbedaan dalam hal waktu komputasi, kompleksitas implementasi, dan akurasi hasil. Dimensi optimal yang dihasilkan diharapkan dapat meningkatkan efisiensi sistem grounding dan memberikan kontribusi signifikan dalam bidang perlindungan petir.

Grounding rods are crucial components in lightning protection systems, effectively channeling lightning currents into the ground. Soil resistivity and the installation depth of the grounding rod are critical parameters influencing its performance. Therefore, this study aims to determine the optimal dimensions of the grounding rod to minimize grounding resistance while considering the cost of grounding rod materials. The optimization methods used in this study are Monte Carlo and Particle Swarm Optimization (PSO) for comparative purposes. The Monte Carlo method is used in simulations with COMSOL software to evaluate the variations in soil resistivity and depth on the performance of the grounding rod. The simulation data is then analyzed using the PSO method in MATLAB to find the optimal dimensions of the grounding rod that yield minimal grounding resistance. The results from both optimization methods are then compared to assess the effectiveness and efficiency of each method. The study's findings indicate that both Monte Carlo and PSO methods can identify the optimal dimensions of the grounding rod considering variations in soil resistivity and depth. However, the comparison of these two methods shows differences in computation time, implementation complexity, and result accuracy. The optimal dimensions obtained are expected to enhance the efficiency of the grounding system and contribute significantly to the field of lightning protection.
