SIFAT MEKANIKA KAYU PINUS (PINUS MERKUSII JUNGH ET DE VRIESE) ASAL DESA TAENDE MORI ATAS MOROWALI UTARA SULAWESI TENGAH
ABSTRACT: The mechanical
characteristic of wood also known as the strength of wood, the characeristic
that related to the wood endurance in
holding load and content that given to it. The research aimed to find out the
wood mechanical characteristic that involved parallel press strength of fiber,
static curve strength (MOE) and broken strength (MOR) of pine (Pinus merkusii
Jungh et de Vriese) wood from Taende village Upper Mori subdistrict Morowali
Utara District Central Sulawesi. The observed Variabel of the research was the
mechanical characteristic of Pine wood that involved the parallel press
strength of fiber, the static curve strength (MOE) and the broken strength
(MOR). The experiment design that used in the research was Complete Ramdomized
Design (CRD) with three treatments of
posititions in the stem: base, middle and tip. Each treatment was repeated six
times, so there would be 36 units of
experiment samples. The result of the research showed that the rate of the
parallel press strength and the highest rate
of the base was 453,61 kg/cm2, the middle was 324,50 kg/cm2 and the lowest rate of the tie was 269,53
kg/cm2. The highest rate of the static curve strength (MOE) on the base was
62.400,19 kg/cm², the middle was 60.716,01 kg/cm² and the lowest rate on the
tip was 59.479,52 kg/cm². The higjest rate of the broken strength (MOR) on the
base was 464,80 kg/cm², the middle was 427,81 kg/cm² and the lowest rate on the
tip was 386,28 kg/cm². Statistically, the position in the stem had unreal effect to the parallel press strength of
fiber MOE and the broken strength MOR of the pine wood was axial one direction.
