Abstract

Climate change has triggered increased rainfall intensity and exacerbated the risk of disasters, especially landslides in the tropical hilly areas of Ambon Island. This community service activity was carried out in Karang Panjang Village, Sirimau District, Ambon City, to increase public awareness and knowledge about the impacts of climate change and preventive strategies for slope landslides. Activities include geoscience and bioengineering-based education and direct practice of planting vetiver grass (Chrysopogon zizanioides) as a natural solution for slope prevention. The evaluation results showed an increase in public understanding by 24.7% after participating in a series of socialization activities. In addition to gaining knowledge about the causes and dynamics of slope stability, residents were also equipped with skills to plant and maintain vetiver independently and sustainably. This program proves that an educational and participatory approach can be a strong foundation for community-based disaster mitigation.

Abstract

This study investigates the tsunami hazard potential induced by the activity of the South Buru Thrust Fault on the coastal areas of Ambon City through two-dimensional (2D) numerical modelling using the COMCOT v1.7 software, while incorporating three-dimensional (3D) slip evolution from the fault scenario. The earthquake scenario was set at Mw 8.3 based on fault length, width, and slip potential estimates, representing an extreme seismic event in the region. By integrating 3D slip evolution into the 2D tsunami model, the approach accounts for spatial variations in vertical displacement along the fault plane, directly influencing tsunami generation and propagation. The simulation results show significant spatial variations in tsunami run-up heights and inundation zones, with maximum run-up recorded at Kapahaha (13.08 m, arrival time ~832 s) and Slamet Riyadi Port (12.02 m, arrival time ~786 s). In comparison, minimum values occurred in Ambon's northern and northeastern parts (<1 m). The affected area and inundation distance from the shoreline also vary, e.g., Kapahaha (12,813 m², 159 m) and Slamet Riyadi Port (414,158 m², 1,213 m). Areas experiencing the highest tsunami inundation are Latuhalat (>5 m), followed by Galala–Wayame–Laha (3–5 m) and Paso–Rumah Tiga–Hative Kecil (2–4 m). The distribution of tsunami waves is influenced by coastal morphology, wave direction, and the presence of bays and capes, which can either amplify or block waves. Further analysis highlights the effects of seafloor topography, coastal morphology, and wave propagation pathways on run-up heights and arrival times. These findings underscore the importance of considering multi-segment rupture models, 3D deformation, and coastal morphology in tsunami hazard assessments and contribute to more realistic, source-specific mitigation strategies in tectonically complex regions such as Ambon.

Abstract

Indonesia sebagai negara dengan tingkat kerentanan bencana tinggi, khususnya gempa bumi, memerlukan upaya mitigasi yang komprehensif. Fokus program pengabdian kepada masyarakat (PKM) ini adalah memberikan pengetahuan tentang mitigasi bencana kepada siswa SMA Angkasa Pattimura, Ambon menggunakan media game virtual. Dalam pelaksanaannya, program ini mengadopsi model ADDIE (Analysis, Design, Develop, Implement, Evaluate) sebagai metode pengembangan. Tahap analisis melibatkan pemahaman terhadap peserta didik, tujuan instruksional, pengembangan instruksional, dan tujuan pembelajaran. Desain media virtual game menggunakan software articulate storyline 3 dengan komponen utama, seperti pendahuluan, materi, virtual game, dan kuis. Implementasi dilakukan di SMA Angkasa Ambon pada Oktober 2022, dengan evaluasi berupa hasil kuis dan wawancara. Hasil program menunjukkan bahwa media virtual game mitigasi bencana gempa bumi berhasil dikembangkan dengan baik dan dapat diakses melalui laptop atau smartphone. Penyampaian materi kepada siswa SMA Angkasa Pattimura Ambon berlangsung interaktif dan diikuti oleh 34 siswa. Evaluasi berdasarkan hasil kuis menunjukkan pemahaman yang memuaskan dari siswa terkait mitigasi bencana gempa bumi. Dengan demikian, program ini memberikan kontribusi positif dalam meningkatkan pemahaman siswa terkait mitigasi bencana gempa bumi. Program ini diharapkan dapat meminimalisir kerugian saat terjadi bencana dan meningkatkan kesiapsiagaan masyarakat Indonesia dalam menghadapi ancaman bencana alam.

Abstract

Ngurbloat Beach, located in the Kei Islands, Maluku Province, has a varied coastal ecosystem, including benthic habitats that play an important role in ecological balance and sustainability of marine resources. This study aims to map the spatial distribution of benthic habitats including substrates in the waters of Ngurbloat Beach by utilizing Allen Coral Atlas data. The analysis was conducted through classification of high-resolution satellite images using remote sensing and geographic information system (GIS) methods. The results showed that the total mapped area was 183 ha. Benthic habitats in this area are dominated by coral reefs (18.99%), seagrasses (0.85%), microalgae (2.93%) and sand substrates (16.42%), rocks (39.44%) and dead corals (22.7%). Oceanographic factors and anthropogenic activities in the waters of Ngurbloat Beach affect the distribution of benthic habitats, especially coral reefs that have suffered serious damage and need to be rehabilitated. The utilization of Allen Coral Atlas data proved effective in providing accurate spatial data for benthic ecosystem mapping, which can support conservation efforts and sustainable management of coastal resources.

Abstract

Maluku merupakan daerah kepulauan dengan kekayaan sumber daya alam yang melimpah, seperti gunung, pantai, hutan tropis, dan terumbu karang yang memiliki potensi besar untuk dikembangkan sebagai objek wisata. Salah satu wilayah yang menjanjikan adalah Desa Rumahkay di Kecamatan Amalatu, Kabupaten Seram Bagian Barat. Desa ini memiliki potensi alam berupa hasil hutan, perkebunan, pantai, dan air terjun. Namun, potensi tersebut belum banyak diketahui masyarakat luas sehingga pengembangan Desa Rumahkay sebagai destinasi wisata masih kurang terpublikasi. Untuk menjawab permasalahan tersebut, dilaksanakan Program Kemitraan Masyarakat (PKM) dengan tujuan menerapkan teknologi digital berupa GPS, Avenza Map, dan ArcGIS dalam pemetaan potensi sumber daya alam. Kegiatan ini menghasilkan peta informatif yang menunjukan potensi sumber daya alam Desa Rumahkay terutama objek wisata alam. Metode pelaksanaan mencakup sosialisasi, pelatihan pemetaan menggunakan GPS dan Avenza Map, dan survei pemetaan lapangan. Melalui pemetaan berbasis perangkat digital, berbagai potensi wisata alam Desa Rumahkay dapat terdokumentasi secara sistematis. Beberapa produk yang dihasilkan dari kegiatan ini meliputi peta jalur objek wisata alam air terjun yang menampilkan informasi grafis jalur tercepat menuju objek wisata alam tersebut serta peta fasilitas umum yang menggambarkan mengenai sebaran infrastruktur dan sarana pendukung yang tersedia bagi masyarakat maupun wisatawan. Adapun hasil evaluasi dari pelaksanaan kegiatan ini menunjukkan melalui metode pelatihan secara langsung (learning by doing) mampu secara signifikan meningkatkan pemahaman masyarakat dan ketertarikan masyarakat terhadap pengembangan Desa Rumahkay sebagai desa wisata yang berkelanjutan.

Abstract

The initiative to promote earthquake disaster mitigation strategies in Liang Village is designed to enhance the community's awareness and readiness in the face of potential earthquakes. This effort is crucial due to Maluku's earthquake-prone geographical characteristics, underscoring the need to equip residents with essential knowledge and mitigation skills. The approach includes socialization, engaging discussions, and training in using basic technologies like the Avenza Maps and INATEW. Residents from various hamlets participated, with support from the Maluku Provincial BPBD. The outcomes reveal a notable improvement in participants' comprehension, as shown by the increase in pretest and posttest scores. Furthermore, the community's active involvement in establishing disaster preparedness groups reflects heightened collective awareness. The use of simple technology also enhances residents' capability to map their surroundings. This initiative has effectively become an educational, practical, and innovative model for community-based disaster risk reduction.
