      Abstract
      Kayu randu (Ceiba pentandra L. Gaertn.) termasuk jenis kayu cepat tumbuh dan berkerapatan rendah berkisar 0,21-0,28 g.cm-3. Hal ini membatasi pemanfaatan jenis ini khususnya untuk tujuan struktural. Peningkatan kualitas dan kekuatan kayu dapat dilakukan dengan menerapkan proses densifikasi. Efektivitas proses ini dapat ditingkatkan dengan memberikan pra perlakuan berupa delignifikasi parsial. Tujuan penelitian ini adalah menganalisa sifat fisis dan mekanis kayu randu terpadatkan dengan pra perlakuan delignifikasi parsial. Proses densifikasi diawali dengan penerapan pra perlakuan delignifikasi parsial menggunakan campuran CH3COOH dan H2O2 (1:1) pada konsentrasi 20%, dan 25%, serta akuades (0%), dilanjutkan dengan proses densifikasi pada suhu 150 °C dan 160 °C selama 30 menit. Hasil penelitian menunjukkan bahwa penerapan pra perlakuan delignifikasi parsial pada proses densifikasi mampu meningkatkan sifat fisis dan mekanis, serta stabilitas dimensi kayu randu terpadatkan, kecuali nilai T/R-rasio. Penggunaan suhu 150 °C dengan konsentrasi 25% merupakan perlakuan optimum pada kayu randu terpadatkan.
       
      Randu wood (Ceiba pentandra L. Gaertn.) is a fast-growing wood species with a low density ranging from 0,21-0,28 g.cm-3. This limits the utilization of this species especially for structural purposes. Improving the quality and strength of wood can be done by applying densification process. The effectiveness of this process can be improved by applying partial delignification as pre-treatment. The purpose of this study was to analyze the physical and mechanical properties of densified randu wood with partial delignification as pretreatment. The densification process begins with the application of partial delignification as pretreatment using a mixture of CH3COOH and H2O2 (1:1) at concentrations of 20%, and 25%, as well as aquadest (0%), followed by the densification process at 150 °C and 160 °C for 30 minutes. The results showed that the application of partial delignification as pretreatment in the densification process was able to improve the physical and mechanical properties, as well as the dimensional stability of randu densified wood, except for the T/R-ratio value. The use of 150 °C temperature with 25% concentration is the optimum treatment in term of randu densified wood.
