“…The correlation between the amount of PVAc adhesive and the value of the SWR is possibly due to the ability of adhesive in strengthening the particle bond. Therefore, the higher the adhesive content, the stronger the capacity to hold the screw inserted in the particleboard [34]. The factor contributes to the SWR value includes the internal bonding in which the higher the internal bonding value, the stronger the screw withdrawal resistance [2] The density of particleboard also affects the strength of particleboard in holding nails and screws.…”

The quality of particleboard made from broad-leaved acacia branches and PVAc adhesive was investigated. A non-factorial completely randomized design (CRD) with adhesive contents of 10%, 15%, and 20% was employed. The parameters for testing physical properties included moisture content, density, water absorption, and thickness swelling. The parameters for testing the mechanical properties were modulus of elasticity, modulus of rupture, internal bonding, and screw withdrawal resistance. The results indicates that the concentration of PVAc adhesive has a significant effect on both physical and mechanical properties of the fabricated particleboards. The LSD further test indicates that particleboard with 20% adhesive content has the highest value in strength tests and meets the Indonesian National Standard (Standard Nasional Indonesia/SNI) 03-2105-2006. It is suitable for non-structural indoor (interior) element.

Samama wood (Anthocephalus macrophyllus (Roxb) Havil) is a fast-growing and lesser-utilized wood species that has inferior properties; therefore, its quality needs to be improved. This research aimed to determine the effect of citric acid impregnation at high curing temperatures on the dimensional stability and mechanical properties of wood. Citric acid solution with 10% concentration (w/w) was impregnated into wood samples by vacuum-pressure method (-0.5 cmHg, 30 min; 0.7 MPa, 3 h), followed by curing process at 140℃, 160℃, and 180℃ of temperature for 1 h. In comparison, the other wood samples were heat treated at the same temperatures and time. The results showed that the increase in curing and heat temperatures for both treatments were directly proportional to the dimensional stability, but inversely proportional to the mechanical properties. Citric acid impregnated had higher density, dimensional stability, and mechanical properties, except for modulus of rupture, than that of heat treatment. The optimum temperature is suggested at 160℃ in both treatments.

“…Papan partikel yang baik adalah papan partikel yang mengandung semakin banyak bahan baku yang memiliki peran sebagai penguat seperti kulit buah kopi, limbah kayu gmelina, dan limbah kayu meranti untuk mengurangi rongga pada papan partikel. Rongga yang semakin terisi akan menyebabkan ikatan antar bahan penyusun semakin lebih kuat (Wulandari et al, 2020). Hasil analisis keragaman pada Tabel 7 menunjukkan bahwa seluruh perlakuan variasi komposisi campuran partikel berpengaruh nyata terhadap nilai kekuatan tarik pegang sekrup papan partikel.…”

Limbah hasil hutan dan pertanian saat ini belum memiliki nilai ekonomis yang baik maka pembuatan papan partikel bisa menjadi solusi. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik fisis dan mekanis papan partikel dari campuran serbuk gergajian kayu sengon dan kulit buah kopi menggunakan perekat dekstrin dari pati tepung onggok. Pembuatan dekstrin dilakukan dengan cara menyemprotkan asam klorida (HCl) dengan konsentrasi 5% sebanyak 5 mL terhadap 80 g pati tepung onggok, kemudian dioven pada suhu 130°C selama 3 jam. Selanjutnya, dilakukan pembuatan papan partikel dengan target kerapatan 0,6 g/cm3. Untuk mengetahui komposisi campuran bahan yang optimal, papan partikel dibuat dengan empat komposisi bahan campuran antara serbuk gergajian kayu sengon dengan kulit buah kopi dengan perbandingan berat: 100%:0%, 75%:25%, 50%:50% dan 25%:75%. Perekat dekstrin yang digunakan dalam pembuatan papan partikel sebanyak 20% dari berat kering tanur partikel dan dilakukan pengempaan pada suhu 185°C serta tekanan 20 kg/cm2 selama 10 menit. Hasil pengujian sifat fisis menunjukkan bahwa nilai kerapatan 0,49-0,64 g/cm3, kadar air 7,89-9,01%, daya serap air 92,41-167,65% dan pengembangan tebal 11,91-59,90%. Papan partikel dengan komposisi campuran serbuk gergajian kayu sengon dan kulit buah kopi sebanyak 25%:75% telah memenuhi standar pengujian sifat fisis, meliputi: kerapatan, kadar air dan pengembangan tebal, sedangkan nilai daya serap air tidak dipersyaratkan di dalam Standar JIS A 5908: 2003. Hasil pengujian sifat mekanis menunjukkan bahwa nilai internal bond 0,02-0,03 N/mm2 dan nilai kuat tarik pegang sekrup 46,4-144 N. Papan partikel dengan komposisi campuran serbuk gergajian kayu sengon dan kulit buah kopi sebanyak 25%:75% memiliki sifat mekanis optimal, namun demikian tidak memenuhi standar JIS A 5908: 2003.
