Pembuatan Komposit Superabsorben Polimer Berbasis Selulosa dari Serat Aren (Arenga Pinnata Merr) dan Poly Acrylamida Menggunakan Mesin Berkas Elektron

Abstract

The uncertain climate change due to global warming make the Earth's surface temperature be increased, a longer dry season coupled with the uncertainty of rainfall which caused the soil in some places become dry and damaged. This research was conducted on the making of the superabsorben polymer (SAP) of cellulose-based fiber Palm can absorption water up to many times compared to the weight of the polymer, which aims to improve soil properties due to climate change are erratic and can be controlled erosion on steep slopes. The methods used in this research is a method of grating to know the effectiveness of SAP, the determination of the functional groups of the SAP of Aren fiber using FT-IR spectrophotometry, calculate the rate of cellulose Aren fiber in the manufacture of SAP, know the ability of absorption water (swelling) and robustness of SAP in storing water. Making SAP of Aren fiber and polyakrilamid is using an electron beam with dose of radiation 50 kGy. The results of research on testing transplants faction (grafting) and the ability of the water is the absorption (the ratio of swelling) ) in this study SAP with levels of cellulose 77,80 % having results grafting faction of 72,25 % to the ability of the uptake of water as much as 930,72 % , but with SAP cellulose 56,00 % faction obtained the decline in grafting and the ability of the absorption of the water that is 56,15 % and 875,51 % , with this we can conclude that the level of cellulose can influential on high the low transplants faction and the ability of absorption water.
