Introduction Technological advances open up huge crime opportunities. This can be seen from the many cases that come to court about digital crime. The cases handled are about the misuse of technologies such as the internet, hoaxes, fake photos and others. One of the facts that cause cybercrime is the need for computer network technology is increasing. Commercial community activities become important things done by using the computer network. It can be spread all over the country. World activities will last for 24 hours and can be monitored for 24 hours as well. These activities include stock trading, banking, and other financial activities. In cyberspace, any activity can be done. This positively impacts technological advancements and adds convenience for people to exchange information. But this did not escape the negative impact. When pornography rife on the internet, the law can not do much in the past. The development of internet technology triggered the emergence of cybercrime. This action will harm others. Cybercrime activities include credit card theft, hacking multiple sites, intercepting other people's data transmissions, and manipulating data by preparing several programs such as viruses to commit such crimes. Cybercrime has become a threat to international stability, so the government is difficult to compensate crime techniques done with computer technology, especially internet and intranet networks. Cyberspace is a media without limits because it is connected to a network of computers connected to the world. It does not recognize territorial or state boundaries. This crime will cause its problems, especially in criminal law and jurisdiction. Jurisdiction is the power or competence of state law against people, objects or events. This is the principle of state sovereignty, equality of state and principle of non-interference. Jurisdiction is also a vital and central form of sovereignty that can transform, create or terminate a legal relationship or obligation. This research tries to explain how the legal system will be applied to cybercrime perpetrators based on certain violations. Each violation has a different legal act. By applying jurisdiction, cybercrime actors will be reduced for the sake of state stability and sovereignty.

Any criminal activity that occurs in the digital world or through the internet network is referred to as internet crime. Cybercrime also refers to criminal activity on computers and computer networks. This activity can be done in a certain location or even done between countries. These crimes include credit card forgery, confidence fraud, the dissemination of personal information, pornography, and so on. In ancient times there was no strong law to combat cybercrime. Since there are electronic information laws and transactions, legal jurisdiction of computer crime has been applied. Computer networks are not only installed in one particular local area but can be applied to a worldwide network. It is what makes cybercrime can occur between countries freely. This issue requires universal jurisdiction. A country has the authority to combat crimes that threaten the international community. This jurisdiction is applied without determining where the crime was committed and the citizen who committed the cybercrime. This jurisdiction is created in the absence of an international judicial body specifically to try individual crimes. Cybercrime cannot be totally eradicated. Implementing international jurisdiction at least reduces the number of cybercrimes in the world. Keywor ds: Cybercrime, Jurisdiction, Law
