SIFAT FISIK DAN MEKANIK KAYU GERUNGGANG (CRATOXYLON ARBORESCEN Bl) YANG DIDENSIFIKASI BERDASARKAN WAKTU PENGUKUSAN DAN WAKTU KEMPA
Abstract: The increasing
demand for wood every years is not balanced with the availability of raw
materials in nature, especially high-quality wood. Hence the need for an effort
to partially overcome this condition by using low quality wood (III-IV) such as
Gerunggang wood (Cratoxylon arborescen Bl). Samples were made of Gerunggang
wood with size of 30 cm x 8 cm x 4 cm
with a target of 30% reduction in thickness. Physical and mechanical properties
testing refers to the British Standard Methods 373 (1957). Parameters measured
were color and touch impression, water content, density, dimensional changes,
MOE, MOR and MCS). This research used
factorial experiment in a random design complete with 2 factors. Factor A steaming time (50
minutes, 60 minutes and 70 minutes) and factor B pressing time (40 minutes, 60
minutes and 80 minutes) each made 3 times repeats. The results showed
Gerunggang wood was densification by steaming and pressing time produce
physical and mechanical properties better. The best treatment in this research
were at the steaming time treatment 60 minutes and 80 minutes pressing time.
