Abstract

Per tahun 2019, tercatat bahwa volume konsumsi minyak goreng sawit nasional mencapai 16,2 juta kiloliter. Limbah dari minyak bekas penggorengan atau minyak jelantah merupakan salah satu sampah rumah tangga yang dapat mencemari lingkungan. Pada kegiatan pengabdian ini dilakukan sosialisasi dan pembuatan lilin aromaterapi berbahan dasar minyak jelantah. Kegiatan ini dilakukan sebagai upaya pengurangan pencemaran lingkungan akibat limbah minyak jelantah. Lilin aromaterapi adalah jenis lilin yang dibuat dengan penambahan minyak atsiri untuk menghasilkan aroma yang menyegarkan, seperti minyak sereh. Penggunaan minyak atsiri sereh memiliki efek relaksasi karena aromanya yang menyegarkan. Hasil sosialisasi dan pelatihan mendapatkan respon dan antusiasme yang baik dari peserta. Lilin aromaterapi yang dibuat dari minyak jelantah memiliki kualitas yang baik dan dapat mengubah minyak jelantah menjadi barang yang lebih bernilai ekonomis..

Abstract

The development of environmentally friendly methods for nanoparticle synthesis has gained increasing attention. Black pepper essential oil contains secondary metabolites that act as both reducing and stabilizing agents, making it a promising green alternative in silver nanoparticle (AgNP) synthesis. This study aims to investigate the effect of pH and synthesis time on the yield and characteristics of AgNPs synthesized using black pepper essential oil via the sonochemical method. AgNP synthesis was carried out using the sonochemical method by adding black pepper essential oil to a silver nitrate solution. AgNPs were synthesized at pH levels of 8, 9, and 10 with reaction times of 30, 60, and 90 minutes. The obtained AgNPs were analyzed for yield, UV-Vis absorbance, and particle size distribution. The results demonstrated that yield increased with higher pH and longer synthesis time, reaching a maximum of 58.12% at pH 10 and 90 minutes. UV-Vis analysis confirmed the presence of AgNPs with absorption peaks between 400500 nm. The particle size ranged from 9.66 to 348 nm, indicating size variability influenced by synthesis conditions. These findings highlight the potential of black pepper essential oil as a green and sustainable approach for AgNP synthesis, offering eco-friendly benefits for various applications.
