Pengaruh Tingkat Penekanan dan Posisi Pengambilan Sampel pada Dolok terhadap Penyerapan Rubinate oleh Sitka Spruce yang Dipanaskan Dahulu dengan Microwave

Karnita Yuniarti, Jeff Hann

Sari


Penggunaan energi mikrowave pada tingkat cukup tinggi dapat menyebabkan perubahan dimensi kayu akibat patahnya beberapa struktur kayu yang lemah. Modifikasi lebih lanjut dengan resin diikuti penekanan kayu selama proses fiksasi resin dapat memperbaiki kualitas kayu tersebut. Penelitian ini bertujuan untuk menganalisis pengaruh penekanan selama proses fiksasi resin rubinate dan faktor posisi pengambilan sampel kayu terhadap penyerapan rubinate oleh Stika spruce yang sebelumnya dipanaskan dengan mikrowave. Hasil penelitian menunjukkan bahwa penyerapan akhir dipengaruhi oleh tingkat penekanan yang digunakan selama proses fiksasi resin dan kurang dipengaruhi oleh faktor posisi pengambilan sampel kayu. Penyerapan akhir rubinate juga dipengaruhi oleh interaksi antara kedua faktor tersebut.


Kata Kunci
