Abstract
This research was to aimed the quality of particle board made from sago waste on citric acid. Particle board made from sago waste from Ambawang Subdistrict, the Regency of Kubu Raya. The research was conducted at the Wood Workshop Laboratory, Wood Processing Laboratory, Faculty of Forestry and PT. Duta Pertiwi Nusantara. Particle size with 8 mesh – 10 mesh and Adhesive citric acid levels were 10%, 20%, 30%, 40%. Mixing material is done manually. Particle board is made with size 30 cm x 30 cm x 1 cm with target density of 0,6 gr/cm2. specificpressure of 25 kg/cm2 and temperature of 1800 C for 15 minutes. The quality of particle board comply with a request JIS A 5908-2003 is increasing adhesive citric acid 20%.Keyword : citric acid, particle board, sago waste
Highlights

Summary
Nilai rerata daya serap air papan berbentuk cair akan menyebabkan partikel disajikan pada Gambar 3. Nilai Rerata Daya Serap Air (%) Papan Partikel Ampas Sagu (The average water absorption (%) of particle board sago waste). Hal ini diduga karena kadar perekat asam sitrat yang sedikit memenuhi standar Japanese Industrial Standard (JIS A 5908 – 2003). Hal ini menyebabkan ikatan antara partikel kurang kompak sehingga papan mudah diduga karena semakin banyak perekat yang di tambahkan maka akan mengembang. Hasil penelitian ini menyebabkan ikatan antara perekat dan sejalan dengan penelitian Suroto (2010) yang mengemukakan bahwa jika kadar partikel semakin kompak (Suroto 2010). Hal ini diduga karena semakin banyak jumlah asam sitrat maka akan semakin banyak jumlah air yang ditambahkan dalam pembuatan papan partikel, sehingga papan yang dihasilkan lebih lembek dan tidak mampu menahan beban ketika tekanan diberikan. Keteguhan Patah (Modulus of Rupture/ MOR) Hasil pengujian Modulus of Rupture / MOR disajikan pada Gambar 6
