Abstract

Solar energy utilizes sunlight to produce electricity via photovoltaic (PV) panels, which act as a medium for capturing solar energy. PV panels are widely used for efficiency, cost-effectiveness, and scalability. Common challenges in solar energy capture include geographical location, weather conditions, and fluctuations in the direction of incoming sunlight. So, a control system is important. In countries with adequate sunlight, photovoltaic (PV) panels are designed with control systems that track the movement of the sunlight. Given the continuous motion and changing position of the sun, the development of advanced dual-axis solar trackers with intelligent control systems remains an ongoing area of research. Control methods used by sun tracker system is Proportional-Integral-Derivative (PID) with auto-tuning. For increase performance PID control is important to optimize PID at sun tracker sytem dual axis, simulated by MATLAB Simulink. GEO algorithm is optimization method using metaheuristic. GEO is founded on the intelligent adjustments on attack propensity and cruise propensity that golden eagles perform while searching for prey and hunting. In this study, the GEO algorithm will be used to optimize PID with a dual-axis solar tracker simulated by MATLAB Simulink. This research compares three model designs: uncontrolled, PID control using auto-tuning, and PID using GEO tuning (PID-GEO). The result of the simulation, we get comparison performance from three model designs is PID-GEO has the fastest settling time, smallest overshoot and undershoot of all model designs. Where the overshoot horizontal axis is 11. 372% and the undershoot is 0%, that also at the vertical axis, the overshoot is 11. 559% and undershoot is 0%. It can be concluded that PID-GEO has the best performance compared to PID auto-tuning and uncontrolled. So, this research concludes that GEO can be used to optimize PID control

Abstract

Desa Grogol, Kecamatan Diwek, Kabupaten Jombang memiliki 6 dusun sehingga memiliki Usaha Mikro Kecil dan Menengah (UMKM) dengan jumlah besar serta memiliki potensi untuk dikembangkan. Tim PKM dari Universitas Darul 'Ulum Jombang yang diwakili oleh Kelompok H dalam program Kuliah Kerja Mahasiswa (KKM) mengadakan pelatihan digital marketing yang dirancang secara sistematis, termasuk tahap pre-test, pembelajaran, pelatihan intensif, dan post-test. Metode yang digunakan dari kegiatan pengabdian masyarakat ini berfokus pada peningkatan kapasitas UMKM agar dapat bersaing di era digital dengan pemberian pelatihan kepada para UMKM tentang pemahaman digital marketing. Kegiatan terdiri dari 3 tahap, mulai dari tahap prapelaksanaan, tahap implementasi, serta tahap evaluasi. Guna menentukan efektivitas pelatihan, analisis hasil pre-test dan post-test memakai aplikasi statistik SPSS. Program ini memberikan hasil yang positif, terbukti dari hasil analisis uji Paired T-test yang signifikan, hasil pre-test didapatkan mean sebesar 46,59, hasil post-test didapatkan mean sebesar 63,18, dan diperoleh hasil signifikansi uji Paired T-test sebesar 0,000 yang mengindikasikan terdapat peningkatan kompetensi terhadap UMKM setelah mendapatkan pelatihan dan pendampingan terkait digital marketing.
