Spons dari Tepung Glukomanan dengan Penambahan Charcoal
Abstrak. Telah dilakukan pembuatan spons dengan bahan dasar tepung glukomanan dengan penambahan charcoal. Pada percobaan ini dipelajari pengaruh dua jenis larutan alkali yaitu larutan Na2CO3 dan larutan NaOH terhadap karakteristik spons yang dihasilkan. Spons dibuat dengan cara melarutkan tepung glukomanan dalam air yang dilanjutkan dengan membusakan larutan dengan penambahan Sodium Laureth Sulfate (SLS) bersama-sama dengan penambahan charcoal. Larutan basa ditambahkan untuk membentuk gel basah. Spon kering diperoleh setelah proses thawing dan pengeringan dengan sinar matahari.Karakterisasi spons dilakukan dengan melihat rongga menggunakan mikroskop kamera serta menganalisis daya serap air, daya ekspansi spon basah serta nilai iod teradsorpsi. Spons yang dihasilkan mempunyai rongga dengan ukuran antara 0,1 mm sampai 0,25 mm.
