Abstract

Perkembangan Ilmu Pengetahuan dan Teknologi saat ini sangat mendukung setiap kegiatan salah satunya adalah kegiatan keagamaan dan Easyworship merupakan salah satu dari aplikasi teknologi. Adapun tujuan dari kegiatan pengabdian ini adalah mentransfer pengetahuan dan teknologi pada masyrakat non produktif salah satunya adalah gereja. Dengan adanya kegiatan sosialisasi dan pelatihan easyworship mampu meningkatkan potensi pemuda-pemudi terhadap kreativitas dan inovatif dalam pelayanan peribadatan. Metode yang digunakan dalam kegiatan ini adalah pelatihan dengan membentuk small grup agar pelatihan ini lebih fokus kepada individu dan terkesan tidak monoton. Tim pengusul juga mendampingi tiap kelompok jika pada saat pelaksanaanya ada kendala yang dihadapi. Hasil dari kegiatan pengabdian ini adalah pemuda-pemudi di GBKP Tanjung Raja memperoleh pemahaman tentang aplikasi tersebut dan mereka juga semakin antusias untuk mengembangkan kemampuan masyarakat dalam mengoperasikan aplikasi easyworship yang menjadi perwujudan telah adanya kolaborasi teknologi di tempat tersebut.

Abstract

This study aims to evaluate the effect of the mass ratio on the capacitance of electrodes made from TiO-based composites. The composites were synthesized using a wet chemical method and applied using the doctor blade technique, incorporating TiO2 and rGO derived from coconut shell activated carbon. Our findings reveal that at a 1:1 mass ratio, the atomic composition of Ti and O was non-uniform, although there was evident adherence of TiO2 elements to the sample surface. In contrast, at mass ratios of 1:3 and 1:5, a decrease in the concentration of Ti atoms and an increase in O atoms were observed, indicating a reduction in Ti oxidation. SEM analysis further revealed that particle size significantly impacts capacitance: smaller particle sizes yielded higher capacitance. In the 1:1 mass variation, the discharge process was protracted, taking up to 29.3 minutes and generating an electrical energy of 0.000413 joules with a capacitance of 489 µF. These insights are pivotal for optimizing the composition and mass ratio, fostering the development of electrode materials characterized by enhanced capacitance and energy efficiency. Such advancements hold promising potential for a range of applications in the energy storage sector.Keywords: Activated Carbon, Capasitance, Supercapacitor
