Pengembangan Sistem Analisis Fungsi Kognitif Berbasis Website Untuk Evaluasi Pengaruh Aromaterapi Melalui Data Eeg
Abstract
Kemajuan teknologi digital telah berdampak negatif terhadap kemampuan atensi berkelanjutan, yang berimplikasi pada penurunan produktivitas di ranah akademik maupun profesional. Penelitian ini merancang sistem terpadu berbasis web dan EEG guna mengukur pengaruh aromaterapi terhadap fungsi kognitif, melalui integrasi aplikasi SART yang mencatat respons secara akurat dan modul EEG yang menganalisis sinyal otak untuk mengidentifikasi komponen ERP sebagai indikator atensi. Proses validasi melalui User Acceptance Testing membuktikan bahwa seluruh aspek sistem berfungsi dengan tingkat keberhasilan 100%. Hasil pengujian menunjukkan bahwa kelompok kontrol memiliki tingkat deteksi ERP (P200, P300, P500) yang lebih tinggi dibandingkan kelompok eksperimen, khususnya penurunan signifikan komponen P200 pada kanal AF7. Walaupun akurasi kedua kelompok hampir serupa, kelompok eksperimen menunjukkan waktu respons lebih cepat, namun disertai dengan tingkat kesalahan yang lebih besar. Oleh karena itu, aromaterapi lemongrass dalam konteks studi ini tidak terbukti mampu meningkatkan kemampuan atensi berkelanjutan secara signifikan.
