Terorisme merupakan kejahatan luar biasa dan menjadi ancaman dunia karena merupakan suatu tindakan kekerasan yang mampu menimbulkan suasana teror atau rasa takut secara meluas sehingga menimbulkan banyak korban. Di Indonesia sendiri pada awalnya sasaran dari serangan terorisme memfokuskan pada simbol-simbol negara barat, akan tetapi sejak tahun 2010 jaringan terorisme tersebut beralih sasaran terhadap pemerintah khususnya Polri yang dianggap sebagai salah satu pihak untuk melakukan penanganan terorisme. Para pelaku teroris menganggap satuan kepolisian sebagai thogut karena dianggap menghalangi kegiatan mereka. Adapun dari pihak kepolisian sendiri menerapkan suatu upaya guna melakukan pencegahan terhadap serangan terorisme, yaitu peningkatan sistem pengamanan internal yang berlaku bagi seluruh kantor polisi di Indonesia. Oleh karenanya, tujuan dari skripsi ini adalah untuk mengetahui sistem pengamanan internal Kepolisian Resor X, Jawa barat sebagai kantor polisi pertama yang terkena serangan bom secara langsung oleh teroris. Penelitian ini merupakan penelitian deskriptif dengan menggunakan pendekatan kualitatif, serta metode pengumpulan data berupa wawancara dan observasi. Adapun analisis temuan data dilakukan dengan menggunakan Teori Pencegahan Kejahatan Situasional dan Pencegahan Kejahatan Berbasis Komunitas. Hasil penelitian menunjukkan bahwa terdapat perubahan dan peningkatan sistem pengamanan internal di Polres X setelah terjadinya serangan terorisme serta adanya pelibatan masyarakat sekitar Polres X dalam pencegahan kejahatan terorisme.

Terrorism is considered as an extraordinary crime and also a world threat because of their violent acts. Other than that, terrorism is capable of creating an atmosphere of terror which cause moral panic as well as the victims. Before 2010, the target of terrorism attacks in Indonesia mainly focused on symbols of westernization. However, now it has changed that the terrorism network has shifted their target to attack the government, especially against the Police, which is considered as one of the parties responsible for handling terrorism in Indonesia. The terrorists assume that the police are part of the thagut because they have intervened in their activities. As for the police themselves, to prevent terrorist attacks they are implementing an effort to prevent terrorism attacks, namely by increasing their internal security system that applies to all police stations in Indonesia. Therefore, the aim of this thesis is to find out the internal security system of the X Police in West Java as the first police station to be bombed by a terrorist. This study used descriptive qualitative research, and the data was collected from interviews and observations. Furthermore, the study was analyzed with situational crime prevention theory and community-based crime prevention. The results showed that there were changes and improvements in the internal security system at Polres X after the terrorism attack. In addition, the involvement of the community around Polres X also has an important role to prevent the terrorism attacks.
