PENGEMBANGAN TEKNOLOGI LASER SEBAGAI BIOSTIMULATOR UNTUK PENGGEMUKAN DAN PEMATANGAN TELUR KEPITING BAKAU (Scylla serrata)

DEVELOPED OF LASER TECHNOLOGY DEVELOPMENT AS BIOST1MULATOR FOR FATTENINGAND EGG 1l1ATURATION OF MUD CRAB (Scylla serrata)

Abstract

Mud crab was one of the fisheries commodities that havea high economic prospect and good market opportunity, local and export. Soft Laser technology could be achieved using He-Ne and Diode as biostirnulator  for fattening,  egg maturation stage and duration of mud crab. This research was application experimental  that used to Factorial Complete Random Design  with treatment laser with wavelength  differences  (632,8 nm and 635 nm) and Factor II:  Control or no treatment, shooted in theeyestalk point (M) and shooted  in reproduction  point (R) with l O replication. The result of this study indicated that utilization  soft laser influence growth and egg maturation  stage and duration of mud crab. Treatment shooted laser He-Ne (LI) to produce growth and egg maturation stage and duration of mud crab was betterthan not shooted  laser. Treatment shooted soft laser He-Ne (LI) at the eyestalk point to produce better growth as 1,8393   gram and egg maturation  stage and duration of mud crab was highest,  to produce 2 egg maturation stage of full stage as 4 crabs of9 crabs reached  stadia two (LI) with duration of egg maturation  means 9,88   ± 2, 15 days  and control (1,2233  to growth and egg maruration  stage reached 3 crabs to 2 full stage of 7 crabs with duration means 17,33±4,42days).
