The purpose of this study is the obstacles to law enforcement against perpetrators of criminal acts of theft of cultural heritage objects in Kupang, East Nusa Tenggara. This research is an empirical juridical research that examines a legal event that occurs through a statute cause approach. Data collection is carried out with two events, namely interviews and document studies. The data obtained is then presented descriptively qualitative. The results showed that the obstacles experienced by the community and law enforcement officials are: the absence of reports to the police and coordination with other stakeholders; the caretaker's mistake in understanding evidence; stakeholders who observe cultural heritage have not functioned optimally; and there is no PPNS cultural heritage in NTT. Prevention efforts taken in the form of prevention include: organizing cultural heritage promotion and counseling campaigns; providing training or technical guidance to all cultural heritage caretakers in NTT; the government supports the presence of the Cultural Preservation Agency (BPK); and collaborating with stakeholders. Law enforcement against criminal acts of theft of cultural heritage objects is still not optimal. Therefore, suggestions for the results of this study are the socialization of cultural heritage protection and cultural heritage laws comprehensively.  All stakeholders must be more adaptive and responsive. BPK needs to cooperate with local governments and related institutions to draft a special regulation or law governing the establishment of a special agency for the supervision of cultural heritage sites. Make a government regulation regarding the establishment of a special cultural heritage police.

(2) Efforts to overcome conflict between crocodiles and humans have been carried out by establishing a SATGAS or task force for dealing with conflict between humans and wild animals and consists of two units, where one unit is tasked with dealing with the community and the other unit tasked with dealing with wild animals. There are also several government agencies in it to respond to reports quickly and handle them according to SOPs or standard operational procedures for handling conflicts between humans and wild crocodiles which serve as standard guidelines for handling conflicts reported by the public. As well as efforts from the government, there have also been short-term efforts such as outreach and long-term efforts such as conducting more in-depth research on crocodiles. Based on the results of this research, it is hoped that there will be awareness from all components, both society and government, so as not to excessively convert land so that it destroys the natural habitat of crocodiles and causes crocodiles to escape into public areas.
