Abstract

The utilization of boiler ash from bark burning in pulp and paper industry as a conditioning agent of peat gambut soil inindustrial plantation forest has been carried out. The utilization of boiler ash as much as 5 – 10 kg/plant on peat soil,  as a vegetation media of Acacia crasicarpa conducted in the green house and the field of timber estate. Its influences on productivity and environmental aspect has been observed for 12 months vegetation age. The results showed that there were a significant effect of boiler ash utilization on growth rate and productivity of plantations. Utilization up to 10 kg/plant or 10 tons/ha/plantation period was improving the physical, chemical, and biological properties of boiler soil without detrimental effects to the environment.

Abstract

Ramie waste from result of fiber decomposition process of textile industry contains potential high enough cellulose to be utilized for pulp dissolving making. Diversification usage of pulp dissolving for instance in making of acetate cellulose used for ultra-filtration membrane having excellence character such as hydrophilic and easy to be biodegradable. Process of membrane making was initiated with pulp dissolving making altered to become acetate cellulose product. It was then dissolved in acetone and formal amide in varying concentration. Solution of acetate cellulose was mould and the product was washed. Making and testing of acetate cellulose membrane made from commercial pulp dissolving and testing of of commercial membrane of acetate cellulose were also carried out from comparison.Result indicates that acetyl content of 38.54% of acetate cellulose from pulp dissolving could be obtained. This value approach acetyl content of acetate cellulose made from commercial pulp dissolving (39.19%) and acetyl content made from commercial membrane of acetate cellulose (39.58%). Acetate cellulose membrane that produced from pulp dissolving ramie waste have low water flux (22.92% L/jam.m2) with the rejection value of 74.2% if it is compared with commercial acetate cellulose membrane. Scanning Electron Microscope (SEM) analysis indicates that membrane structure that obtained has pore diameter in the range of 0.08 μm - 0.1 μm  that is categorized membrane asymmetric of ultra-filtration membrane type.Keywords: biodegradable, flux, hydrophylic, ramie waste, cellulose acetate membrane, rejection, ultra-filtrationINTISARILimbah rami dari hasil proses penguraian serat industri tekstil mengandung selulosa cukup tinggi yang potensial dimanfaatkan untuk pembuatan  pulp dissolving. Diversifikasi penggunaan pulp dissolving diantaranya untuk pembuatan selulosa asetat sebagai bahan membran ultrafiltrasi yang mempunyai keunggulan bersifat hidrofilik dan mudah dibiodegradasi. Proses pembuatan membran diawali dengan pembuatan pulp dissolving yang dirubah menjadi produk selulosa asetat. Selulosa asetat yang dihasilkan dilarutkan dalam aseton dan formal amid pada berbagai variasi komposisi. Larutan selulosa asetat selanjutnya dicetak dan produknya dicuci. Pembuatan dan pengujian membran selulosa asetat dari pulp dissolving komersial, dan pengujian membran selulosa asetat komersial dilakukan juga sebagai pembanding.Hasil menunjukkan bahwa kadar asetil 38,54% selulosa asetat dari pulp dissolving limbah rami dapat diperoleh. Nilai ini mendekati kadar asetil yang diperoleh dari pulp dissolving komersial sebesar 39,19% dan juga kadar asetil dari selulosa asetat komersial sebesar 39,58%. Membran selulosa asetat yang dihasilkan dari pulp dissolving limbah rami mempunyai fluks air yang lebih rendah yaitu 22,92 L/jam.m2 dengan hasil rejeksi mencapai 74,2% bila dibandingkan dengan membran selulosa asetat komersial.  Hasil analisa Scanning Electron Microscope (SEM) menunjukkan bahwa struktur membran selulosa asetat yang dihasilkan memiliki diameter pori antara 0.08 μm - 0.1 μm yang termasuk kategori membran asimetrik jenis membran ultrafiltration.Kata kunci: biodegradasi, fluks, hidrofilik, limbah rami, membran selulosa asetat, rejeksi, ultrafiltrasi
