Abstract

The voucher
program
entitled
"Manufacturing
Ornamental Stone
Cutting
Machine for
Small Building
Ornament Industries" aims to
increase
productivity
of the
CV. PURBA
KRIASTA especially
in cutting
ornamental
stone
being
produced" It
also
wants
to know the
size and
productivity
of such ornamental stone machine.
The
steps of
this manufacturing ornamental stone
cutting
machine are
planning,
machine
manufacturing,
and
training fbr industry
partner
workers.
The
planning
step includes
:
(l)
designing machine
plan
draft,
(2)
calculating
the
needed
materials,
and
(3)
calculating
the implementation cost
. The machine-manufacturing
step
includes
:
(l)
material cutting to fit the work draft,
(2)
welding,
(3)
assembling,
(4)
electric
installation.
(5)
machine
performance
test, and
(6)
painting.
The training
for industry
partner
workers consists
of :(l) theory and speech
delivery,
(2)
demonstration
of machine using, and
(3)
machine
using
practice
by the
industry
partner
workers.
The result of the
voucher
program
is realization of an ornamental
stone cutting
machine and
skill
achievement
by the
industry
partner
workers
in
the
machine
operation.
The ornamental
stone
cutting
machine was
made of
right-angled
iron frame
sizing 80x80x7 mm,50x50x5 mm, and 30x30x3 mm, combined
with steel
plate
of 3
mm thick. The machine size
is
120 cm length, 60 crn width,
and 190 crn height,
moved by a I
phase
electric motor
power
SEM of I HP and rotation
speed of
2800
RPM. The cooling system
uses
water moved by an aquarium
pump.
The
machinE
performance
and
productivity
especially
for cutting
straight
forms has speed
of 8
to
l0
times faster compared
with manual
cutting having been done
up till
now.
Key words :
stone cutting
machine, and
small
ornamental
stone industry.
