The couple had married in September and the husband found out on the wedding night that his wife was no longer a virgin.
She then said she had been raped one week before the marriage.
Police said Mr Effendi, 30, asked his 20-year-old wife to arrange a meeting with the man she accused of raping her.
He stabbed the man to death and cut off his genitals before setting the car on fire.
He said that he fried the severed genitals and ate them to cure his heartache over the rape.
Police said the couple could be charged with premeditated murder, which carries a maximum death penalty.
