Abstract

Pengabdian kepada masyarakat merupakan salah satu pilar dalam Tridharma Perguruan Tinggi yang dilaksanakan oleh Kelompok Bidang Keahlian (KBK) Telekomunikasi, Teknik Elektro, Universitas Andalas, sebagai upaya memberikan solusi terhadap permasalahan di masyarakat. Kegiatan ini memanfaatkan teknologi wireless router untuk meningkatkan konektivitas internet di Mushala Al-Mahira, Aie Pacah, Padang. Program ini bertujuan mendukung kegiatan keagamaan dan sosial, seperti kajian daring, pelatihan teknologi untuk anak-anak, dan komunikasi internal pengurus mushala. Artikel ini menguraikan tahapan pelaksanaan program yang meliputi survei awal, instalasi perangkat, pelatihan pengelolaan jaringan, hingga evaluasi dampak. Hasil kegiatan menunjukkan bahwa teknologi wireless router secara signifikan meningkatkan akses internet, mempermudah penyebaran informasi, dan mendorong produktivitas masyarakat sekitar mushala. Kegiatan ini membuktikan bahwa teknologi dapat menjadi solusi praktis dan berkelanjutan dalam mendukung transformasi digital di komunitas lokal.

Abstract

The growing demand for sustainable materials for flexible electronics and energy storage applications has driven the development of biodegradable composite films with enhanced electrochemical functionality. This study systematically investigates the effect of MXene loading on the structure, morphology, and electrochemical performance of biodegradable PVA/ZnO/MXene/CNC composite films fabricated by aqueous solution casting. The main contribution of this work is the explicit establishment of a relationship between loading, structure, and electrochemical performance for this multicomponent biodegradable film system under controlled processing conditions. Films containing 20%, 25%, and 30% MXene were prepared with constant ZnO and CNC contents and characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and cyclic voltammetry in 1 M KOH. The crystallinity increased from 20.06% to 27.58% and 44.74% with increasing MXene loading, while FESEM revealed progressively more homogeneous morphology and improved filler dispersion. These structural changes were accompanied by a marked enhancement in electrochemical response, with current density increasing from 425.18 to 876.71 and 1480.25 A/m², and specific capacitance rising from 0.921966 to 1.682536 and 2.860035 F/g for 20%, 25%, and 30% MXene, respectively. The 30% MXene film exhibited the best overall performance, indicating that higher MXene loading within the investigated range promotes more continuous conductive pathways and greater electroactive surface accessibility. These findings provide useful insight for designing biodegradable composite films for sustainable flexible energy-storage applications.
