This is proven by the increasing number of crimes that occur in Indonesia. The perpetrators of these crimes do not only come from outside the home but can also come from their own homes or family. The problem approach that will be used in this study is a normative juridical approach and an empirical approach. Based on the results of the research and discussion in the previous chapter, the following conclusions can be drawn: Factors that cause a father to commit a crime of deception and persuade a child to have intercourse are due to several factors such as internal factors in the form of the defendant's lack of understanding of religion, the defendant's mental state was also a causal factor, as well as the existence of the defendant's sexual abnormalities such as pedophilia where the defendant prefers young children compared to someone of his age. In addition to internal factors, external factors also influenced the defendant in committing the crime, such as environmental conditions and the circumstances where the defendant lived which supported the occurrence of the crime, then he could not give vent to his sexual desires because his wife was not at home, the defendant's low education, and the media. and technological advances were also a part of the external factors that caused the defendant to commit these actions. Criminal liability by a father who commits a crime of deception and persuades a child to have intercourse is that the Defendant is sentenced to imprisonment for 13 (thirteen) years and a fine of Rp. 100,000,000.00 (one hundred million rupiahs) provided that the fine is not paid is replaced by imprisonment for 6 (six) months and the period of arrest and detention that the Defendant has served is deducted entirely from the sentence imposed.
