LASMARIA MANIK: The Influence of Temperature and Time Pressing of
Physical and Mechanical Properties Particle Board from Waste Oil Palm Trunk
with Isocyanate Adhesive Supervised by RUDI HARTONO and TITO SUCIPTO.
The main objective of the research is the substitution (replacement)
diminishing wood and to cope with the waste oil palm trunks are increasing. The
research highlights on the influence of temperature and time pressing of the
physical and mechanical properties by using isocyanate adhesive and resistance
agains termite soil particles board. This research method in comparison with SNI
03-2105-2006 and use completely randomized factorial design 2 factors:
temperatures (150oC, 160oC and 170oC) and times (3 minutes, 5 minutes, 7
minutes and 9 minutes) and compressed with pressure of 25 kgf / cm2. The results
showed that the temperature and the interaction between temperature and time
did not significantly affect the physical and mechanical properties except the time
factor that significantly affect the moisture content and water absorption.66 HalamanSkripsi Sarjan
Asetilasi Kayu Kemiri (Aleurites moluccana), Durian (Durio zibethinus), dan Manggis (Garcinia mangostana)
FEBRINA HERYANI TARIGAN. Wood Acetylation Of Aleurites moluccana,
Durio zibethinus, And Garcinia mangostana woods. Supervised by Luthfi
Hakim and Rudi Hartono.
The alternative that was used to solve the problem of the unstable
dimensions of wood fruits and the susceptible of the wood from termines attack is
an attempt preservation of wood by chemical modification of wood acetylation.
The purpose of this research are to evaluate the stability dimension and the
quantity of the preservatives that absorbed into the Aleurites moluccana, Durio zibethinus, and Garcinia mangostana woods, and to know the durability of wood from termite attack by acetylation with laboratory tests and grave test.
This research carried out by soaking the kemiri wood, durian wood, and
manggis wood for 2 weeks with the concentration of acetic acid solution 10%,
15%, 20%, and 25%. The results showed that concentration of 15% has good stability dimension 67.8% and in addition 44.41%. The greatest retention from the concentration 25% by 7.73 gr/cm3 this his means that the greater the concentration of acetic acid solution, effect to the higher retention becomes which means resistance and the wood becomes better67 halamanSkripsi Sarjan

HARTONO and guided by TITO SUCIPTO .
Durian wood is a type of timber from community forest are commonly
used as a wood carpentry . The purpose of this study is to evaluate the physical
and mechanical properties of wood durian after microwave heating with time and
different thicknesses . Durian wood thickness variations were tested in this study
was 2 cm , 4 cm and 6 cm and length of heating with microwaves is 0 minutes , 5
minutes , 10 minutes and 15 minutes as much as 3 replications . The results of
measurements of physical properties based on the British Standard ( BS : 373 .
1957) suggests testing the water content ranges from 28.17 % -90.08 % , a density
range of 0.53 g/cm3-0 , 0.82 g/cm3 , depreciation ranged from 2 , 27 % -6.95 % .
In testing the mechanical properties of durian wood MOE values obtained ranged
kg/cm3-84054 kg/cm3 64129 , MOR values ranged from 573.23 kg/cm3-709 , 03
kg/cm3 and value hit 240.83 kg/cm3-284 parallel fibers , 08 kg/cm3 . Microwave
heat treatment on durian wood causes decreased water content and density of the
wood , while the mechanical properties of thick wooden significantly affect MOR ,
and does not significantly affect the MOE and press the parallel fibers.70 HalamanSkripsi Sarjan
Asetilasi Kayu Rambutan (Nephelium lappaceum L), Cempedak (Artocarpus integer Merr), dan Rambai (Baccaurea montleyana Muell. Arg)
JENDRO ZALUKHU Wood acetylation of Nephelium lappaceum, Artocarpus
integer, and Baccaurea montleyana woods. Guided by LUTHFI HAKIM and
RUDI HARTONO.
Termites are wood destroying organisms that cause harm and
considerable damage to buildings in Indonesia. Therefore, there should be
methods of termite attack on buildings. Method of chemical modification of wood
used in this study is acetylation using acetic acid solution is applied to the wood
of fruit (Nephelium lappaceum, Artocarpus integer, and Baccaurea montleyana
woods). The purpose of this study was to test the dimensional stability, and
retention test measures the resistance of wood against termite attack on
Nephelium lappaceum, Artocarpus integer, and Baccaurea montleyana woods
after acetylation.
The method is carried out three types of wood soaked in each
concentration of acetic acid solution (control, 10%, 15%, 20% and 25%). The
results showed that the acetylation of wood to improve dimensional stability
(ASE). In addition, the process also increases the acetylation of wood resistance
to termite attack. This is shown by the retention of preservative that occurs in
wood diasetilasi. Acetylation with acetic acid solution of 25% has the highest
retention value, and the weight loss due to termite attack the lowest. This means,
the process of acetylation can increase the resistance of wood against termite
attack.70 halamanSkripsi Sarjan

Termite (Macrotermes gilvus Hagen). Supervised by Rudi
Hartono and Ridwanti Batubara
Sengon wood (Paraserianthes falcataria) has low-grade durability and very
durable from biological attack, such as subterranean termites
(Macrotermes gilvus). One way toincreasethe durability ofsengon wood is to
insert liquid smoke. Hazelnut shells waste is usedas araw materialliquid smoke.
The aim of this research are to identify chemical compunds from hazelnut shells
waste liquid smoke using Gas Cromatography Mass Spectroscopy (GCMS) and to
evaluate the effect of liquid smoke on sengon wood against subterranean termites
with concentration of liquid smoke 0%, 5%, 10%, 15% and 20%. The method used
is soaking the wood into liquid smoke.Thisresearchevaluated thedominant

. This study used nonfactorial completely randomized design and the results are compared with
standard JAS 243: 2003.
The results showed that glue spread variation of UF adhesive on
laminated board does not affect to the value of all physical and mechanical
properties. Water content and delamination test values fullfilled the standard of
JAS 243:2003, while the MOE and MOR values have not fullfilled the standard of
JAS 243:2003. The value of density, water content, water absorption, thickness
swelling, delamination ratio, MOE and MOR were 0.48-0.51 kg/cm3
