abstract: Telah dilakukan penelitian mengenai konversi nanoselulosa menjadi gula alkohol
menggunakan nanokomposit LaCr0,99Ti0,01O3/NHGO dengan perbandingan berat
0,1:1; 0,3:1; 0,5:1. Nanokomposit disintesis dengan metode sol-gel menggunakan
pektin sebagai agen pengemulsi, metode freeze drying , metode sonikasi dan
kemudian dikarakterisasi dengan FTIR, XRD, SEM-EDX, dan DRS UV-Vis.
Hasil analisis XRD menunjukkan terbentuknya 2 fase kristal utama dari struktur
perovskit ABO3, yaitu LaCrO3 dan LaTiO3 serta diperoleh ukuran kristal
berdasarkan metode Scherrer berkisar 26,95-46,21 nm. Hasil analisis SEM-EDX
menunjukkan bahwa nanokomposit memiliki morfologi dengan beragam bentuk
serta nilai energi band-gap ketiga nanokomposit berada di kisaran 1,45–1,58 eV.
Nanoselulosa kulit pisang kepok dipreparasi melalui tahapan delignifikasi,
bleaching, dan sonikasi dengan asam nitrat serta diperoleh ukuran kristal yaitu
27,55 nm dan indeks kristalinitas 24,13%. Konversi nanoselulosa menggunakan
nanokomposit LaCr0,99Ti0,01O3/NHGO dilakukan dibawah radiasi sinar UV
dengan variasi waktu 60, 120, 180, 240, dan 360 menit. Hasil konversi
menunjukkan bahwa persentase nanoselulosa terkonversi tertinggi yaitu 57,78%
dengan nanokomposit LaCr0,99Ti0,01O3/NHGO (0,5:1) dan konsentrasi glukosa
tertinggi sebesar163,056 ppm dengan menggunakan nanokomposit
LaCr0,99Ti0,01O3/NHGO (0,1:1).

In this research, the conversation of nanocellulose into sugar alcohol had been
studied using the LaCr0,99Ti0,01O3/NHGO nanocomposite by the variation of
weight ratio, as follows: 0.1:1.0; 0.3:1.0; and 0.5:1.0. These nanocomposites were
synthesized by the following methods: sol gel using pectin as an emulsifying
agent, freeze dry, sonication and characterized by FTIR, XRD, SEM-EDX, and
UV-Vis DRS. Based on the XRD analysis result, two main crystalline forms from
ABO3 perovskites had been obtained, namely LaCrO3 and LaTiO3, with size
ranging from 26.95 to 46.21 nm based on the Scherrer method. The result of
SEM-EDX implied that these nanocomposites had various morphologies and their
band-gap energy ranging from 1.45 to 1.58 eV. Nanocellulose from Kepok banana
peel was prepared by the following phases: delignification, bleaching, and
sonication using HNO3. As a result, the size of nanocellulose crystal was 27.55
nm and its crystallinity index was 24.13 %. The conversion of nanocellulose using
LaCr0,99Ti0,01O3/NHGO nanocomposites were carried out under UV-irradiation by
variation of time, as follows: 60, 120, 180, 240, and 360 minutes. As a result, the
highest percentage of converted nanocellulose was 57.78% with the
LaCr0,99Ti0,01O3/NHGO nanocomposite (0.5:1.0) in 300 minutes process, while
the highest concentration of glucose was 163.056 ppm using the
LaCr0,99Ti0,01O3/NHGO nanocomposite (0.1:1.0) in 240 minutes process.
