KESIMPULAN DAN SARAN
A. Kesimpulan
1. OSB kombinasi dengan bambu Andong dan Betung memberikan sifat
fisis, mekanis statis dan dinamis yang lebih tinggi dibanding bambu Ampel.
2. OSB dengan panjang strand 13 cm memberikan sifat fisis, mekanis
statis dan dinamis yang terbaik dibanding OSB dengan panjang 7 cm dan 10 cm.
3. Berdasarkan model regresi sederhana, nilai SWV belum dapat
digunakan untuk menduga nilai modulus elastisitas statis MOEs, modulus patah MOR, dan modulus elastisitas dinamis MOEd dari
OSB dengan kombinasi susunan 3 jenis bambu dan variasi panjang strand
B. Saran
Dalam pembuatan OSB kombinasi dari beberapa jenis bambu sebaiknya dilakukan pengujian sifat fisik dan mekanik dari bahan baku bambu tersebut
sebelumnya.
