Use extweaks since you are using siyah. Open extweaks > press "CPU" tab if you are not on it by default > Hotplug mode > set to "Second core always-off".

Thanks in advance.

May I ask why would you want to shut down second core?

If not for the battery or performance why then just doesn't make any sense!
