Abstract

Pemantauan maritim terpadu sangat krusial di tengah ancaman kerusakan ekosistem global akibat eksploitasi perairan secara ilegal. Literatur saat ini masih terfragmentasi pada pembahasan komponen teknologi secara terpisah sehingga menyisakan kesenjangan riset yang nyata dalam pemetaan holistik interaksi lintas disiplin antara domain komputasi, infrastruktur fisik, dan target ekologi dalam satu kerangka kerja fungsi ganda. Penelitian ini bertujuan mengisi celah tersebut dengan memetakan lanskap literatur global terkait penerapan strategi penggunaan ganda sonar pasif untuk deteksi penangkapan ikan ilegal dan pemantauan ekologi maritim. Desain penelitian memadukan analisis bibliometrik kuantitatif dan tinjauan literatur sistematis kualitatif. Sebanyak 217 dokumen final berhasil diekstraksi dari pangkalan data Scopus pada rentang publikasi tahun 2006 hingga 2026 dengan mengikuti protokol penyaringan ketat. Analisis data dieksekusi menggunakan perangkat lunak pemetaan visual untuk mengevaluasi jaringan kemunculan bersama kata kunci dan metrik performa objektif. Hasil analisis mengungkap lonjakan publikasi secara eksponensial semenjak tahun 2019 yang dipelopori oleh Tiongkok pada volume produksi dan Amerika Serikat pada dampak sitasi. Pemetaan topologi jaringan memunculkan tiga klaster tematik utama. Klaster pertama menyoroti integrasi arsitektur kecerdasan buatan untuk otomatisasi pelacakan armada kapal gelap. Klaster kedua berfokus pada peran diagnostik ekoakustik untuk mengukur tingkat stres mamalia laut dan degradasi terumbu karang. Klaster ketiga menegaskan posisi hidrofon resolusi tinggi sebagai fondasi perangkat keras penangkap sinyal presisi. Kesimpulan penelitian ini membuktikan konvergensi antara sensor akustik mutakhir dan algoritma komputasi cerdas sanggup menciptakan sistem pengawasan laut yang akurat dan bersahabat dengan lingkungan. Keberhasilan implementasi berskala global pada masa depan akan sangat bergantung pada optimalisasi komputasi tepi dan kolaborasi pembagian data lintas yurisdiksi perairan.

Abstract

Urban water bodies such as situ play a crucial role in maintaining hydrological, ecological, and spatial balance in the region, yet their existence is increasingly threatened by urbanization, settlement expansion, and uncontrolled land conversion. Situ Cikaret is one of the water bodies in Bogor Regency experiencing high development pressure amid the growth of the Cibinong area. This study aims to analyze the landscape transformation of Situ Cikaret over the period 1901–2025 using a spatial-historical approach to identify changes in water body area, morphological changes, and surrounding land use dynamics. The research employs descriptive-quantitative methods based on spatial-temporal analysis, integrating 1901 colonial maps, multitemporal Landsat imagery, high-resolution imagery, and Geographic Information Systems. Historical maps were georeferenced using four control points, achieving a Root Mean Square Error of ±2.11 meters. Classification accuracy tests yielded an overall accuracy of 89% and a Kappa coefficient of 86.26%, indicating high data accuracy. The results show that the water body area of Situ Cikaret shrank from 49.97 hectares in 1901 to 21.08 hectares in 2025, a reduction of 57.82%. Additionally, the settlement area increased significantly from 14.78 hectares to 205.61 hectares, accompanied by morphological changes such as narrowing, loss of water body branches, and fragmentation due to landfilling activities. This study concludes that long-term urbanization is the dominant factor in the landscape transformation of Situ Cikaret and underscores the importance of protecting situ buffer zones in sustainable spatial planning.

Abstract

Volcanic ash poses a serious threat to aviation due to its abrasive nature and its tendency to melt at high temperatures, as evidenced by the 1982 British Airways incident at Mount Galunggung. The eruption of Mount Lewotobi from November 7 to 18, 2024, caused ash dispersion that disrupted operations at 13 airports, resulting in the cancellation of hundreds of domestic flights and dozens of international flights. This study employs a qualitative descriptive method, utilizing secondary data, to evaluate how the impacts of the eruption on aviation were managed. The results show that the response was carried out effectively in accordance with Regulation No. PM 95 of 2018, with no serious incidents reported. This was achieved through coordinated dissemination of VONA, VAA, and SIGMET reports, as well as the issuance of ASHTAM and NOTAM. Recommendations are focused on enhancing coordination, strengthening monitoring, and updating aviation operational procedures.

Abstract

Indonesia is one of the countries with the highest level of geospatial disaster risk due to its position on the Pacific Ring of Fire and its exposure to earthquakes, tsunamis, volcanic eruptions, floods, and landslides. The increasing complexity and frequency of disasters, exacerbated by climate change, demands a faster, more accurate, and integrated monitoring system. However, previous studies have focused more on the technical aspects of disaster monitoring without comprehensively examining the strategic role of satellite technology in strengthening Indonesia's national resilience. This gap is the basis for this study. This study aims to analyze the contribution of satellite technology in disaster mitigation and assess how satellite data integration can strengthen national resilience to geospatial threats. The method used is a systematic literature review of reputable international publications from 2014 to 2025 that discuss remote sensing technology, InSAR, damage mapping, early warning systems, and geospatial integration for disaster risk management. The results of the study show that satellite technology plays an important role in three main aspects: (1) real-time disaster monitoring through multisensor data capable of covering a wide area; (2) improving the accuracy of early warning systems for various geospatial disasters; and (3) strengthening national resilience through support for damage mapping, rapid response, strategic decision-making, and inter-agency coordination. The novelty of this research lies in the development of an integrative synthesis that links the use of satellite data with Indonesia's national resilience framework, as well as the affirmation of the need to integrate satellite technology into national disaster management policies. These findings have important implications for strengthening modern mitigation systems and adapting to the escalation of geospatial risks in the future.

Abstract

The safety of shipping and the resilience of maritime infrastructure are affected by the accuracy of the early warning system against extreme weather. The use of Geospatial Intelligence (GEOINT) acts as an integrative framework that combines remote sensing data, spatial analysis, and the interpretation of geographic information for the increasing need for technology-based early detection in the face of increasingly complex marine climate dynamics, both for civilian and national defense interests. The purpose of this research is to analyze the development of global research over the past 25 years on this topic, as well as relate it to maritime infrastructure defense and resilience policies. The methodology used is bibliometric with a quantitative analysis approach to Scopus and Google Scholar publication data, as well as visualization using VOSviewer. The analysis includes the mapping of keyword trends, thematic clusters, institutional actors, and the evolution of research related to GEOINT, remote sensing, and maritime early warning systems. The results show significant improvements in the topic of satellite utilization (MODIS, Sentinel) and the integration of GEOINT big data and spatial analytics for early warning systems, but research on its application in the context of maritime defense policy is still limited. These findings provide strategic direction for the development of GEOINT as a data-driven policy support instrument that supports national shipping resilience and military preparedness in strategic maritime areas. The study also recommends a cross-sectoral research agenda that is more adaptive to the threat of extreme marine weather.
