Abstract

Kekuatan maritim merupakan salah satu instrumen strategis yang penting bagi keamanan dan kedaulatan Indonesia, terutama di tengah dinamika geopolitik kawasan Indo-Pasifik. Salah satu elemen penting dalam kekuatan maritim adalah kapal selam yang mampu menciptakan deterrence effect, yaitu kemampuan mencegah agresi lawan melalui persepsi risiko dan kerugian tinggi. Penelitian ini bertujuan untuk menganalisis pengaruh peningkatan deterrence effect kapal selam terhadap wilayah maritim Indonesia. Metode yang digunakan adalah quantitative research dengan populasi praktisi, akademisi, dan personel pertahanan, serta sampel purposive sebanyak 50 responden. Data dikumpulkan melalui kuesioner berskala Likert dan dianalisis menggunakan uji validitas, reliabilitas, regresi linier sederhana, uji t, dan uji F. Hasil penelitian menunjukkan seluruh instrumen valid (r hitung 0,684–0,801 > r tabel 0,278) dan reliabel (Cronbach’s Alpha 0,812–0,861). Koefisien regresi 0,684 dengan R² 0,581 membuktikan bahwa 58,1% variasi pengaruh wilayah maritim dijelaskan oleh deterrence effect kapal selam. Uji t (7,685 > 2,011; p=0,000) dan uji F (59,05 > 4,04; p=0,000) menunjukkan pengaruh signifikan secara parsial dan simultan. Kesimpulannya, peningkatan deterrence effect kapal selam secara nyata memperkuat keamanan, kedaulatan, stabilitas kawasan, dan aktivitas ekonomi maritim Indonesia.

Abstract

Abstract. The North Natuna Sea is often the site of various threats to Indonesia's maritime sovereignty, including territorial violations by foreign vessels, illegal fishing, and unauthorized survey and exploration activities. These threats require a rapid, precise, and coordinated defense response to maintain regional stability. The Indonesian Navy (TNI AL) implements an adaptive defense strategy, utilizing routine patrols using warships and reconnaissance aircraft, technology-based surveillance such as radar and Vessel Monitoring System (VMS), and inter-agency coordination. This approach ensures that any incidents of violations can be detected early and responded to effectively. Qualitative analysis shows that the effectiveness of the TNI AL's defense depends on personnel readiness, strategic planning, and the involvement of coastal communities. The physical presence of the TNI AL in the waters, combined with scheduled patrols and rapid response, has a preventive effect on illegal activities. In addition, coordination with relevant agencies and the use of technology strengthen threat detection and mitigation capabilities, thereby maintaining the security of the border zone. The results of the study confirm that a holistic and responsive defense strategy is a key factor in maintaining the security and sovereignty of the North Natuna Sea. Adapting to the dynamics of threats and strengthening coordination between units enables the Indonesian Navy to maintain an effective presence, while also In addition, coordination with relevant agencies and the use of technology strengthen threat detection and mitigation capabilities, thereby maintaining security in the border zone. The results of the study confirm that a holistic and responsive defense strategy is a key factor in maintaining the security and sovereignty of the North Natuna Sea. Adapting to the dynamics of threats and strengthening coordination between units enables the Indonesian Navy to maintain an effective presence, while minimizing potential risks that could harm Indonesia.
