Abstract

SnO2/ZnO composites were synthesized using the hydrothermal method using Japanese papaya (Cnidoscolus aconitifolius) leaf extract. This study aims to determine the effect of using Japanese papaya leaf extract (Cnidoscolus aconitifolius) on the formation of crystallinity and morphology in synthesizing SnO2/ZnO composites. Synthesis was carried out with variations in mass of 5, 10, and 15 grams using the hydrothermal method for 12 hours at 160°C. The results of X-Ray Diffraction (XRD) characterization show that wide diffractogram peaks are identified as the peaks of the SnO2 compound with a tetragonal structure and sharp peaks are identified as the peaks of the ZnO compound. The Fourier Transform Infrared (FTIR) characterization shows the peak wave number of 665 cm-1 which is the Sn-O-Sn strain and the peaks at wave numbers 598 cm-1 and 501 cm-1 which are the Zn-O strain. Characterization of Scanning Electron Microscopy (SEM) in the synthesis of SnO2/ZnO composites after adding Japanese papaya (Cnidoscolus aconitifolius) leaf extract had relatively reduced particle size and aggregate formation compared to no extract. The best effective mass of Japanese papaya leaf extract (Cnidoscolus aconitifolius) is the mass variation of 15 grams with 28.49 nm crystals.

Abstract

Tujuan pelaksanaan program pengabdian pada masyarakat berbasis riset ini adalah meningkatkan pengetahuan dan keterampilan masyarakat dalam mengolah jambu bol menjadi minuman kesehatan dan memanfaatkan hasil sampingnya sebagai briket arang untuk sumber energi alternatif yang bernilai ekonomis. Pelaksanaan kegiatan pengabdian ini dibagi menjadi 4 tahap yaitu: perencanaan program, pelaksanaan, observasi dan evaluasi, serta refleksi. Pada pelaksanaan program, dilakukan implementasi program kegiatan yang meliputi peningkatan pengetahuan dan keterampilan, demonstrasi dan pembinaan beserta pelatihan teknologi buah jambu bol menjadi minuman kesehatan dan briket arang. Program ini berhasil meningkatkan pengetahuan dan keterampilan masyarakat Desa Kemumu dalam memanfaatkan jambu bol (Syzygium malaccense) menjadi minuman kesehatan dan briket arang, yang memberikan alternatif energi terbarukan serta peningkatan ekonomi lokal. Tingkat keberhasilan adopsi teknologi tercermin dari kemampuan peserta mereplikasi prosedur diversifikasi produk tanpa pendampingan langsung.
