| Summary: | Geothermal energy is a potential source of renewable energy in Indonesia that can be
utilized either directly or indirectly. For direct use, geothermal can be utilized to heat outdoor
pond water aquaculture to reach optimum growth temperature of fish, like carp and tilapia
have optimum growth temperature in 29o ± 1oC.
However, the problems of using geothermal energy in outdoor pond that changes in
geothermal temperature that is used as warm water for heating pond water and changes in air
temperature. Both can cause pond water temperature different from desired optimum growth
temperature. Therefore, control system is needed to control flow rate of geothermal fluid to
reach pond water desired temperature 29o ± 1oC.
This research is conducted to simulate and analyze the effect of PID controller in
controlling pond water temperature under geothermal temperature and air temperature
disturbance. With proportional, integral and derivative gain are 3,99, 1,96 and 0,04
respectively, the result shows that PID control is adequate for overcoming the effect of both
disturbance and controlling the pond water temperature at 29o ± 1oC optimum growth
temperature of carp and tilapia. PID controller controls geothermal water supplied to balance
the effect of both disturbance.
