Abstract

Nypa Palm fronds has a high lignocellulose, so it has potential to be used as activated carbon. In this research, activated carbon will be made from Nypa palm fronds using H3PO4 as activator and heated at high temperature. The aim of this research is to know about characterisation of activated carbon from Nypa palm fronds with H3PO4. Activated carbon from Nypa palm fronds was made by 2 M H3PO4 and the carbon powder siz was 80 mesh. It was found that activated carbon from nipa palm fronds has characteristic that are in accordance with technical activated carbon requiremet of SNI 06-3730-1995. It has water content of 3%, ash content of 7,25%, iodine absorbance 1129.41 milligrams per gram, methylene blue absorbance 123.99 milligrams per gram and contains the functional groups C=C and P-O-P. Additional pores can be seen on the surface of the activated carbon when compared to carbon without activation.

Abstract

Ketapang leaves are an example of biomass that can be used to make briquettes. However, ketapang leaves produce a low calorific value, so they require additional ingredients to increase the calorific value, one of which is coconut shell. This research aims to evaluate how variations in raw material composition and adhesive content of tapioca flour affect the quality of briquettes on the parameters of calorific value, water content, ash content, volatile substances, fixed carbon content, and density. The method applied in this research involved mixing ketapang leaf charcoal and coconut shell charcoal, then adding adhesive in the form of tapioca flour. The study results showed that all the briquettes tested met SNI 8966-2021 standards except for the density parameter. The conclusion of this study is that the greater the composition of the briquette raw materials and the lower the adhesive content of tapioca flour, the better the quality of the briquettes. The mixed briquettes that produce the best quality are composed of 20% Ketapang leaf charcoal and 80% coconut shell charcoal. The tapioca flour adhesive that delivers the best quality briquettes is at a percentage of 5%.
