Abstract

Polimer superabsorben (SAP) adalah polimer hidrofilik cross-linked jenis tiga dimensi, yang dapat menyerap dan mempertahankan sejumlah besar air dalam waktu yang relatif singkat. Sintesis SAP dari kitosan, amilum dengan penambahan glutaraldehid, dibuat dua variasi yaitu variasi 1 (kitosan 0,5%, amilum 2%, gluteraldehid 25%) dengan variasi 2 (kitosan 2%, amilum 2%, glutaraldehid 5%). Kedua variasi SAP dilakukan uji degradasi untuk mengetahui perbandingan waktu degradasi massa. Karakterisasi SAP dilakukan dengan Fourier Transform Infrared (FTIR) dan Scanning Electron Microscopy (SEM). Pada uji FTIR menunjukkan adanya reaksi antara gugus amina yang terdapat pada kitosan dengan gugus aldehid yang terdapat pada glutaraldehid. Pada uji SEM didapatkan hasil permukaan dari SAP terlihat sangat kasar dan terbentuk agregat. Uji degradasi didapatkan variasi 1 terdegradasi sempurna pada hari ke-15 dan variasi 2 terdegradasi sempurna pada hari ke-14.

Superabsorbent polymer (SAP) is a three-dimensional cross-linked hydrophilic polymer, which can absorb and retain large amounts of water in a relatively short time. The synthesis of SAP from chitosan, starch with the addition of glutaraldehyde, was made in two variations, namely variation 1 (chitosan 0.5%, starch 2%, gluteraldehyde 25%) with variation 2 (chitosan 2%, starch 2%, glutaraldehyde 5%). Both variations of SAP were subjected to a degradation test to determine the comparison of mass degradatio time. SAP characterization was carried out using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). The FTIR test showed a reaction between the amine group found in chitosan and the aldehyde group found in glutaraldehyde. The FTIR test showed that there was a reaction of amines found in chitosan with aldehydes found in glutaraldehyde. In the SEM test, the surface of the SAP looks very rough and aggregates are formed. The degradation test showed that variation 1 was completely degraded on the 15th day and variation 2 was completely degraded on the 14th day
