ABSTRAKAncaman radikalisme dan terorisme hingga saat ini masih berkembang di Indonesia. Kelompok yang rentan dari pergerakan gerakan radikal ini adalah pelajar sekolah menengah atas, civitas akademika kampus, serta masyarakat umum secara terbatas. Hal ini tentu saja menjadi ancaman serius bagi negara, karena dapat mengancam keamanannasional dan masyarakatnya. Oleh karena itu, perlu dilalukan pencegahan dini terhadap radikalisme yang dapat berujung pada aksi terorisme.

Dalam menjawab persoalan di atas, penelitian ini menggunakan metode kualitatif dengan pendekatan analitis deskriptif, sehingga penelitian ini mendeskripsikan mengenai fenomena gerakan radikal dan aksi terorisme di Indonesua dan menganalisis upaya pencegahan dini yang dapat dilakukan oleh Pemerintah. Hasil penelitian menunjukkan bahwa terdapat dua pola penyebaran radikalisme di Indonesia, yaitu melalui Lembaga Swadaya Masyarakat (LSM) tertentu dan pembentukan kelompok-kelompok kajian. mengingat rentanya masyarakat khususnya kaum pelajar akan ancaman radikalisme ini, maka upaya pencegahan dapat dilakukan dengan memberikan pemahaman bela negara melalui mata pelajaran Pendidikan dan Kewarganegaraan. Dalam pelajaran ini, siswa / mahasiswa diberikan pemahaman mengenai nilai-nilai dasar bela negara, sehingga ancaman dari paham-paham radikalisme terhadap masyarakat dapat dicegah secara dini.Kata kunci: Radikalisme, Terorisme, Bela Negara, Perguruan Tinggi, dan Keamanan Nasional ABSTRACTAbstract:The threat of radicalism and terrorism is still on developing phase in Indonesia.

<p>Perkembangan lingkungan strategis berdampak pada pesatnya perkembangan ancaman asimetris. Kawasan Asia Tenggara merupakan salah satu yang menghadapi ancaman ini. Indonesia sebagai salah satu negara di Kawasan Asia Tenggara melakukan kerja sama Trilateral Cooperation Arrangement untuk menangkal ancaman asimetris khususnya di Laut Sulu. Penelitian ini bertujuan<br />untuk menganalisis strategi Trilateral Cooperation Arrangement sebagai strategi pertahanan Indonesia dalam penanggulangan ancaman asimetris di Kawasan Asia Tenggara. Metode penelitian yang digunakan adalah metode penelitian kualitatif dengan pendekatan studi kasus. Penelitian ini menggunakan teori ilmu pertahanan, konsep strategi, counter terrorism, asymmetric warfare,<br />kerja sama pertahanan, cooperative security, dan deterrence theory. Hasil dari penelitian ini dapat dibagi menjadi tiga yaitu pertama, ancaman asimetris yang terjadi di Asia Tenggara khususnya Laut Sulu terus berkembang dan secara khusus dibagi menjadi terorisme; kejahatan transnasional yaitu perompakan bersenjata dan penculikan untuk tebusan; serta migrasi ilegal. Kedua, dalam<br />pelaksanaannya, Trilateral Cooperation Arrangement (TCA) di Laut Sulu terdiri dari Patroli Laut Terkoordinasi (Coordinated Sea Patrol), Patroli Udara (Air Patrol), Pertukaran Informasi dan Intelijen (Information and Intelligent Sharing) dan Latihan Darat Bersama (Land Exercise). Keempat patroli tersebut merupakan kerja sama strategis yang merupakan suatu kesatuan sehingga tidak<br />dapat dipisahkan perbagian atau fungsinya. Namun dalam pelaksanaannya, terdapat peluang dan tantangan yang perlu menjadi perhatian baik pengampu kebijakan atau pihak operasional. Ketiga, Trilateral Cooperation Arrangement merupakan strategi yang dapat menanggulangi ancaman asimetris yang terjadi di Kawasan Asia Tenggara khususnya di Laut Sulu sejak tahun 2016-2018,<br />namun di tahun 2019 ancaman asimetris di Laut Sulu mengalami peningkatan. Adapun strategi yang digunakan adalah menggunakan kerja sama pertahanan serta menggunakan soft power maupun hardpower yang memberikan efek deterrence kepada pelaku ancaman asimetris. Selain itu, memperkuat kerja sama Kementerian dan Lembaga sebagai pembuat kebijakan, serta TNI dan<br />pemerintah daerah sebagai pelaksana operasional serta aturan pendukung seperti aturan prosedur operasional.</p><p><strong>Kata Kunci :</strong> ancaman asimetris, strategi, Trilateral Cooperation Arrangement (TCA)</p>

The paper aims to analyze how diasporas across the globe can become potential elements in enhancing their home country's national interest. Through social aspects such as citizenship laws, engaging diasporas can be one way to broaden a state’s resources in its defense system. Comparative analysis and assessment are used to elaborate on how various countries – which possess a large number of diasporic communities along with comprehensive law systems that regulate its citizenship issues – are reflected upon and proposed for a modified model within Indonesia's scope. The paper concludes that modification of the Indonesian citizenship law in accordance with the government's strategic Defense Diplomacy is an effective way of enhancing sustainable ties with other countries. This research can be used within the government to consider diasporas as elements of national power. Other areas of study, such as defense studies and security studies, may also benefit. This research offers a unique way in altering Confidence Building Measure (CBM) mechanisms in the scope of Defense Diplomacy Studies that will enhance good relations and comprehensively establish synergies between public diplomacy and defense diplomacy en bloc.

<div><p class="Els-history-head">The development of information technology in the international world impacts cyberspace, covering all aspects of national life. So, the government must understand the condition of cyber security in Indonesia and build a national defense system to overcome various threats that come through cyberspace. ASEAN has become one of the platforms for Indonesia to fight for its national interests to support national security in the cyber field. The purpose of this research is to analyze the efforts to strengthen the national defense system based on five aspects of cybersecurity capacity building to realize Indonesia's defense development in cyber defense security through the role of Cyber Defense Center as an actor in Indonesia's defense diplomacy in enhancing cyber defense security cooperation in ASEAN. These strategies and efforts were analyzed through a qualitative approach, and primary data were collected through interviews with informants from various government agencies. In addition, literature, journals, and related documents are also used as supporting data. These efforts resulted in an agreement in the form of making a cyber-portal between countries and equality of view to continue to conduct cybersecurity training in the form of seminars and workshops to build the capacity of the national defense system.</p></div>
