Synthesis and Structure Characterization of SiO2 from Petung Bamboo Leaf Ash (Dendrocalamus asper (Schult.f.) Backer ex Heyne) [PDF]

Journal of Natural Sciences and Mathematics Research, 2017
The Research about Synthesis and Characterization of SiO2 have been worked. We have synthesized Silica from “petung”bamboo leaf ash as SiO2 source. This step used sol gel methode. SiO2 were characterized by Fourier Transform Infra Red (FTIR) to investigated the stucture andX-Ray Diffaction to know about structure and crystallinity.

Analysis of the Physical and Chemical Properties of Petung Bamboo (Dendrocalamus asper) Charcoal Briquettes

Jurnal Biologi Tropis
Bamboo is a very abundant resource with high diversity. There are 157 types of bamboo in Indonesia, one of which is petung bamboo. Petung bamboo is used as raw material for handicrafts and construction, but much of it remains unused and becomes waste, making it a potential alternative fuel source such as bio-briquettes. This study aims to determine the
