Abstract

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.

Abstract

OPEFB is one source of natural fiber-based composites which have the potential to become activated carbon and nanocellulose. This study aims to synthesize and characterize the activated carbon/alginate/nanocellulose-Cu composite. The characterization used in this study is FTIR and PSA. The synthesis of activated carbon/alginate/nanocellulose-Cu composites began with a process of carbonization and activation with H3PO4 to produce Activated Carbon. Followed by a bleaching process with NaClO2 and a delignification process with Na2SO3 and NaOH to produce Nanocellulose. Alginate using commercial alginate. Furthermore, the three ingredients were mixed until homogeneous and put into a 0.1M CuSO4 solution to produce beads. The results of the characterization of characterization of PSA Nanocellulose obtained a particle size of 41.05 nm and the result of FTIR characterization on the activated carbon/alginate/nanocellulose-Cu composite contained the functional group OH group, triple C bond from stretching alkyne, C=C aromatic group, C-H alkane group, C-O group, the P=O stretching vibration of the P-O-C group and the alcohol OH group expressing the active carbon; there are functional groups of hydroxyl (OH), carboxyl, carbonyl, and C-O-C and –COOH bonds which represent alginate and there are OH functional groups, stretching C-H bonds, C-O stretching, stretching C-C, and β- glucosidic bonds between glucose units which indicate nanocellulose.
