OPTIMASI KONFIGURASI INTER DIGITAL CAPACITORS SENSOR (IDCS) MENGGUNAKAN METODE PARTICLE SWARM OPTIMIZATION

(x). The optimization design is adapted to the mathematical analysis of the permittivity formulation in IDCS. Based on the gradient optimization results, the value of 𝑁 ≠ 1 is obtained, meaning that N cannot be 1. This limitation is in accordance with the principle of parallel plate capacitors, where the requirements for a capacitor configuration are to consist of two plates. For the electrode length variable (L) the Boundary is obtained, namely L≠ 0. After the Boundary for the IDCS configuration is obtained, the second stage is carried out, namely optimization using PSO. The parameters used for optimization are the number of particles = 500, the maximum speed is 20, the learning factor = 2, the inertia weight is 0.8 – 1.2 and the stop condition when it reaches the minimum error. The range of results from the PSO optimization is the width of the electrode 1-3 mm, the distance between the two electrodes is 1-3mm, the number of electrodes is between 3-7, the length of the electrode is 4-7 mm. The values that often appear with the smallest error are a = 3, b = 3, N = 6, L = 5.
