Abstract

The   voucher    program    entitled    "Manufacturing      Ornamental     Stone   Cutting Machine   for Small  Building  Ornament   Industries"   aims to increase  productivity   of the CY. PURBA   KRIAST A 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    areplanning,    machine    manufacturing,     and   training   for  industry   partner   workers.    The planning   step  includes   : (1) designing   machine   plan  draft,  (2) calculating   the  needed materials,   and  (3)  calculating   the  implementation    cost.   The  machine-manufacturing step  includes:    (1)  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   :  (1)   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 rnrn  thick.   The  machine   size  is  120  em  length,   60  em  width,   and   190  em  height, moved  by a  1 phase  electric   motor  power   SEM  of  1 HP  and  rotation   speed  of  2800RPM.   The  cooling   system   uses  water  moved   by  an  aquarium   pump.   The  machine performance    and  productivity   especially   for  cutting  straight   forms  has  speed    of 8 to10 times  faster  compared   with  manual  cutting  having  been  done  lip till now.
Key words:   stone cutting  machine,  and  small ornamental   stone industry.
