Penelitian tentang pengaruh variasi massa partikel kayu dan serat lidah mertua pada core (inti) terhadap sifat fisis dan mekanis papan partikel perekat resin epoksi telah dilakukan.  Sifat fisis yang diuji meliputi kerapatan, kadar air, dan daya serap air sedangkan pengujian sifat mekanis meliputi kuat lentur, kuat tekan dan kuat tekan sejajar. Papan partikel ini dibuat dengan memvariasikan komposisi partikel serbuk kayu dan lidah mertua yang lolos ayakan 50 mesh sebagai filler pada core dengan tiga variasi komposisi yaitu 0%:30%, 15%:15% dan 30%:0% sedangkan kadar resin epoksi 10%. Bagian lapis muka papan dibuat dengan komposisi partikel serbuk kayu yang lolos ayakan 100 mesh sebesar 20% dan kadar resin epoksi 10%. Hasil uji sifat fisis menunjukan bahwa papan partikel komposit memenuhi ketentuan SNI 03-2105-2006 berdasarkan kadar air dan daya serap air, namun memiliki kerapatan yang melewati batas standar SNI 03-2105-2006. Selain itu, uji sifat mekanis yaitu kuat tekan sejajar memenuhi standar SNI 03-2105-2006, sedangkan pada kuat lentur (MOE) dan kuat tekan (MOR) tidak memenuhi standar SNI 03-2105-2006. Variasi massa yang terbaik dalam pembuatan papan partikel yaitu dengan menggunakan variasi massa core antara serbuk kayu (30%) dan serat lidah mertua (0%).
Kata kunci: papan partikel, resin epoksi, serat lidah mertua, dan serbuk kayu.
