Abstract

This review focuses on examining the synthesis and characterization of Carbon Nanodots (CNDs) from the utilization of Tandan Kosong Kelapa Sawit (TKKS) using the microwave method as an environmentally friendly approach. The resulting CNDs were characterized for their optical and structural properties to evaluate their potential application in the field of biosensors. The synthesis process involves carbonizing TKKS at 500℃ for 3 hours, followed by activation using a microwave at 450 Watts for 15 minutes. UV-Vis characterization shows an absorption peak at 280 nm, which indicates n-π* (C=O) and π-π* (C=C). Meanwhile, FTIR characterization aims to determine the presence of the carbonyl C=O functional group at 1990,98 cm-1 and the aromatic C=C bond at 1416,2 cm-1. The CNDs from TKKS exhibit photoluminescent properties and surface functional groupss that enhance adsorption performance and chemical reactivity. This research offers an efficient and sustainable method for synthesizing CNDs, while also being a breakthrough in utilizing biomass wate, particularly TKKS. The findings have the potential for developing carbon materials in environmental and energi applications.

Abstract

Pada penelitian ini membahas tentang pembuatan Reduced Graphene Oxide (rGO) dengan memanfaatkan limbah serabut kelapa sawit dari Aceh. Serabut kelapa sawit termasuk biomassa lignoselulosa berupa serat yang memiliki komponen utama selulosa 59,6%, lignin 28,5%, protein kasar 3,6%, lemak 1,9%, abu 5,6% dan impurities 8%. Metode yang digunakan dalam preparasi rGO adalah metode microwave. Sampel yang telah mendapat perlakuan microwave kemudian dikarakterisasi menggunakan XRD dan SEM untuk mengetahui fasa amorf dan morfologi dari sampel. Pada analisis XRD diperoleh hasil bahwa reduce graphene oxide memiliki fase amorf yang lebih dominan. Kemudian, pada analisis SEM diperoleh hasil bahwa GO dan rGO memiliki perbedaan morfologi pada permukaan sampel, dimana rGO memiliki bentuk lembaran yang lebih tipis daripada GO. Pada penelitian ini dapat diambil kesimpulan bahwa sintesis rGO yang telah dilakukan menggunakan serabut kelapa sawit dengan metode microwave belum sepenuhnya berhasil, dimana masih terdapat kandungan Graphene Oxide (GO) yang tidak tereduksi sempurna menjadi Reduced Graphene Oxide (rGO).
