Metode :

1.

Contoh uji (CU) berukuran 2 cm x 2 cm x 2 cm diambil dari papan

bagian pangkal, tengah, dan ujung masing-masing jenis kayu. Dilakukan

untuk 3 kali ulangan sehingga diperoleh 9 buah CU.

2.

CU ditimbang untuk menentukan berat awal (basah) kemudian CU

dikeringudarakan dengan kipas angin selama 3 minggu, lalu ditimbang

untuk menentukan berat kering udara.

3.

CU yang telah kering udara (KU) dimasukkan ke dalam oven dengan

suhu (103 ± 2)

0

C selama 24 jam dan ditimbang beratnya (berat kering

oven).

4.

Dihitung kadar airnya, dengan rumus :

KA basah (%)

= berat awal – berat kering oven x 100%

berat kering oven

Metode :

1.

Contoh uji (CU) strands berjumlah 100 buah untuk masing-masing jenis kayu

diambil secara acak dari tempat penyimpanan (storage).

2.

CU dikeringudarakan dengan kipas angin selama 3 minggu, lalu ditimbang

beratnya dan diukur dimensinya sehingga diperoleh besar volumenya.

3.

Dimensi panjang dan lebar masing-masing diukur 2 kali ulangan dengan

menggunakan kaliper kemudian dirata-ratakan, sementara dimensi tebal

diukur sekali pada bagian tengah strand menggunakan mikrometer sekrup.

4.

Rumus yang digunakan untuk menghitung berat jenis (specific gravity), yaitu :

Berat Jenis

= kerapatan kayu

kerapatan benda standar

Berat Jenis

= massa/ volume

1 g/cm

3

5. Pengukuran dimensi menghasilkan juga nilai aspect dan slenderness ratio,

yaitu

Lampiran 3 Pengukuran kadar resin padat

Standar : JIS (

Japanese Industrial Standard

)

K6833:1980 untuk kadar resin padat

Metode :

1.

Contoh uji (CU) perekat ditimbang sebanyak 1.5 gram kemudian dimasukkan ke

dalam oven pada suhu (133.5

–

136.5)

0

C selama 58-62 menit.

2.

CU dimasukan ke dalam desikator sampai dingin kemudian ditimbang.

3.

Penentuan kadar resin padat dilakukan 3 kali ulangan

4.

Penghitungan kadar resin padat perekat ditentukan menggunakan rumus :

Keterangan:

RSC

:

1.

Teteskan larutan perekat sebanyak satu tetes (kurang lebih 0.05 ml) ke permukaan

strand

dengan menggunakan pipet.

2.

Tiga detik setelah tetesan perekat tadi jatuh di atas permukaan

strand

dilakukan

pemotretan dengan fotomikroskop.

3.

Penentuan sudut kontak perekat dilakukan tiga kali ulangan untuk masing-masing

jenis kayu dan hasilnya dirata-ratakan.
