Abstract

Penelitian ini bertujuan untuk menganalisis keanekaragaman dan asosiasi pergerakan burung migran di beberapa habitat di sekitar Kota Bogor, Jawa Barat. Pengamatan dilakukan pada bulan Oktober sampai dengan November 2024 di empat lokasi yaitu Situ Gede, Lapangan Walet, Katedral Bogor, dan Kampus IPB Dramaga. Dengan menggunakan metode point count, teridentifikasi 28 jenis burung, termasuk dua jenis burung migran yaitu Elang Madu Oriental (Pernis ruficollis) dan Elang Ekor Biru (Merops philippinus). Indeks keanekaragaman jenis tertinggi (H'=2,87) dan indeks kemerataan (E=0,94) tercatat di Kampus IPB, menunjukkan habitat yang stabil dan heterogen. Jenis burung migran menunjukkan peran ekologis yang berbeda; P. ruficollis sebagai predator puncak menunjukkan interaksi predator, sedangkan M. philippinus menunjukkan perilaku kompetitif memperebutkan makanan dan tempat bertengger dengan jenis burung lokal. Keberadaan burung migran ini menunjukkan pentingnya Kota Bogor sebagai tempat persinggahan di Jalur Terbang Asia Timur-Australasia. Studi ini menggarisbawahi pentingnya kualitas habitat dalam mendukung populasi burung penghuni dan burung migrasi dan memberikan wawasan tentang interaksi spesies selama migrasi.

Abstract

Ekosistem mangrove memiliki peran penting dalam menjaga keseimbangan lingkungan pesisir serta berpotensi dikembangkan sebagai objek ekowisata yang berkelanjutan. Di Kecamatan Sungai Apit, Kabupaten Siak, keberadaan hutan mangrove menjadi peluang sekaligus tantangan dalam pengelolaan berbasis masyarakat. Penelitian ini bertujuan untuk mengetahui tingkat partisipasi masyarakat dalam pengelolaan objek ekowisata mangrove. Metode penelitian yang digunakan adalah deskriptif kualitatif. Data dikumpulkan melalui observasi lapangan, wawancara mendalam, dan studi literatur. Penelitian dilakukan di tiga kampung: Kayu Ara Permai, Mengkapan, dan Sungai Rawa. Hasil penelitian menunjukkan bahwa partisipasi masyarakat meliputi kontribusi pemikiran, tenaga, harta benda, dan keterampilan, namun belum merata. Kampung Kayu Ara Permai menunjukkan partisipasi lebih aktif karena dukungan dari pihak luar dan keterlibatan internal. Sementara itu, keterbatasan pengetahuan, minimnya fasilitas, dan kurangnya pendampingan menjadi penghambat utama di dua kampung lainnya. Diperlukan kolaborasi berkelanjutan antara masyarakat, pemerintah, dan mitra untuk memperkuat pengelolaan ekowisata mangrove secara berkelanjutan.

Abstract

The Heart Surgery Theory emerges from the ongoing governance crisis in Indonesia's environmental sector, characterized by institutional fragmentation and sectoral disconnection. This theory proposes a collaborative governance approach that emphasizes spatial and temporal synchronization combined with the application of mutual accountability across sectors. The Cantelan mechanism anchors budgetary allocations (DIPA/DPA) to specific priority locations, ensuring the simultaneous presence of forestry, environment, public works, agriculture, and social sectors in critical ecosystems. This study applies a reflective literature review combined with lessons from national and international practices, including TVA (United States), MDBA (Australia), and ICPR (Europe). The results indicate that spatial-temporal locking and mutual accountability reduce bureaucratic inefficiencies, close governance loopholes, and strengthen bureaucratic integrity in ecosystem restoration efforts.

Abstract

The estuarine of Sungai Hitam in Bengkulu City represents a sandy terrestrial ecosystem characterized by a diverse assemblage of ground cover species, which collectively contribute to the ecological functionality of the immediate environment. This study aimed to identify the structural characteristics, species composition, and species diversity of the ecosystem's constituent flora. Fieldwork was conducted from January to February 2018. Data collection involved the systematic placement of 1m x 1m quadrat plots at 20m intervals. Subsequent data analysis utilized the Important Value Index (IVI) and Shannon-Wiener Diversity Index (H') equations. The findings revealed the presence of 79 species distributed across 22 families of ground cover plants. Sphagneticola trilobata (L.) was identified as the dominant species within this area, attributed to its robust adaptive capabilities and invasive characteristics. Despite this dominance, the overall species diversity was classified as high, evidenced by a diversity index value of 3.21. This high index signifies a relatively stable community structure and considerable ecological resilience against environmental disturbances.
