Abstract

The effect of starch addition in chitosan adhesive on the physical and mechanical properties of petung bamboo particleboard from bamboo-sawing waste was investigated in this work. The utilization of bamboo-sawing waste particles as a raw material for particle board manufacturing has been gaining attention due to its waste reduction potential and economic advantages. The results of this study indicated that starch has been proven to enhance the physical and mechanical properties of petung bamboo particleboard. Adding only 4% wt. of chitosan/starch adhesive with a chitosan/starch ratio of 7/3 (w/w) has resulted in an improvement in the physical properties of the particleboard, such as moisture content, thickness swelling, and water absorption. It has also enhanced the mechanical properties of the particle board, including modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding (IB), in comparison to chitosan adhesive without starch addition. Overall, these findings provide insights for further developing chitosan/starch adhesive, especially to produce natural-based adhesives with good bonding quality.

Abstract

Efek rasio maltodekstrin-amonium dihidrogen fosfat (M/ADP) dan metode kempa pada sifat papan partikel bambu petung berkerapatan sedang diselidiki. Rasio maltodekstrin/ADP 100/0, 90/10 dan 80/20 g/g% digunakan pada penelitian ini. Dua metode kempa digunakan yaitu metode kempa 3-tahap (three-step press method) dan kempa 1-tahap (single-step press method) pada lama kempa 5 menit dengan suhu 2000C. Beberapa sifat fisika dan mekanika papan partikel dievaluasi berdasarkan standar Japanese Industrial Standard (JIS) A 5908 dan Standar Nasional Indonesia (SNI) 03-2105 seperti kerapatan, kadar air, pengembangan tebal, keteguhan rekat internal, dan keteguhan lengkung.  Tingkat kecerahan, penyerapan air, kekasaran permukaan, sudut kontak papan partikel, dan kegetasan juga dievaluasi. Hasil penelitian menunjukkan bahwa peningkatan rasio ADP dapat meningkatkan sifat fisika dan mekanika papan partikel bambu petung. Metode kempa 1 tahap menghasilkan sifat papan partikel yang lebih tinggi dibanding dengan metode kempa 3 tahap pada lama kempa 5 menit untuk papan dengan perekat maltodekstrin 100% maupun perekat maltodextrin/ADP. Perlakuan rasio maltodekstrin/ADP 80/20 g/g% dengan metode pengempaan satu tahap pada waktu kempa 5 menit menghasilkan pengembangan tebal dan kekuatan rekat internal yang memenuhi standar JIS dan SNI. Papan partikel untuk penggunaan non-konstruksi dapat dihasilkan pada waktu kempa yang lebih singkat dibanding dengan waktu kempa papan komersial yang berkisar 7-10 menit.
