Sawo sub-district of North Nias Regency has a mangrove ecosystem that has been designated as a Regional Marine Conservation Area (KKLD) with an area of 29,230.85 ha. The 2005 earthquake and tsunami are reported to have caused damage to mangrove ecosystems due to rising land levels. The increase in land surface has resulted in the destruction of mangroves in this area. This impacts the sustainability of the mangrove ecosystem in this region and is important to study. This study aims to analyze changes in mangrove land cover after the tsunami in 2006 to 2022 and to analyze the impact of changes in mangrove land cover. The results found that mangrove land cover continues to experience a reduction in area; in 2006, an area of 139.78 ha continued to decline until the remaining 70.87 ha in 2022. This is due to the increasing population growth that causes mangrove forest degradation and land conversion into agricultural land, plantations, and infrastructure. The increase in population is a driving force, land clearing for settlements and plantations is a pressure factor (Pressures), land use change is a factor of existing conditions (State), and reduced mangrove land area is part of the impact (Impact). Coastal spatial planning and counseling to reforestation is a response (Response). Land conversion to other uses contributes to this area's continued loss of mangrove land.Keywords: Mangrove; Land Cover; GIS; DPSIR

Kepiting bakau merupakan salah satu biota laut yang ada di Desa Jaring Halus, sebuah lokasi yang memiliki banyak potensi perairan. Salah satu jenis biota perairan yang memiliki nilai ekonomi cukup tinggi adalah kepiting, beberapa produk turunannya memiliki potensi dan pasar yang cukup besar. Pengujian logam berat timbal (Pb) harus dilakukan untuk memastikan standar keamanan dan kualitas makanan. Menentukan jumlah logam berat pada kepiting dan bioamplifikasi logam berat pada biota yang bersangkutan merupakan tujuan dari penelitian ini. Metodologi penelitian ini melibatkan analisis laboratorium dengan alat Atomic Absorption Spectroscopy (AAS). Kepiting di Desa Jaring Halus memiliki kadar logam berat Pb sebesar 0,0157 mg/kg di stasiun I, 0,0142 mg/kg di stasiun II, dan 0,0148 mg/kg di stasiun III. Nilai Pb sebesar 0,5 mg/kg yang merupakan batas baku mutu yang ditetapkan oleh SNI 7387:2009, logam berat pada kepiting sebagian besar masih dianggap aman untuk dikonsumsi manusia karena belum melampaui baku mutu. Faktor biokonsentrasi (BFC) kurang dari <250, yang menunjukkan bahwa kepiting memiliki kapasitas yang rendah untuk menyerap timbal (Pb).

Silvofishery merupakan perpaduan antara hutan mangrove dan perikanan dengan memperhatikan kelestarian hutan mangrove yang pengelolaannya akan berdampak positif bagi lingkungan dan sosial ekonomi masyarakat. Pengelolaan yang berlebihan akan menyebabkan fungsi hutan tidak berjalan dengan baik, terutama sebagai jasa ekosistem. Oleh karena itu, tujuan penelitian ini adalah untuk menentukan model silvofishery yang tepat sebagai optimalisasi rehabilitasi mangrove agar pengelolaannya berkelanjutan. Kampung Nelayan dipilih karena masyarakat dominan sebagai nelayan dalam memenuhi kebutuhan hidupnya dan juga hutan mangrove baru saja direhabilitasi sehingga perlu dikelola lebih baik dalam memperoleh hasil laut yang optimal. Penelitian dimulai dengan konsep dan model silvofishery melalui nelayan, masyarakat, dan pengelola lokal. Selanjutnya, pengamatan langsung dilakukan dalam mengumpulkan data tentang kesesuaian silvofishery, kepadatan vegetasi, keanekaragaman biota dan plankton, wawancara dengan nelayan lokal, masyarakat, pengelola dan studi literatur dari studi serupa. Terakhir, penentuan model silvofishery sebagai optimalisasi rehabilitasi mangrove dalam meningkatkan produktivitas hasil laut di Kampung Nelayan menggunakan analisis kesesuaian silvofishery, kepadatan vegetasi, keanekaragaman spesies biota dan plankton, nilai ekonomi mangrove, dan nilai kelayakan usaha.

Climate change is one of the most significant global threats to the survival of wildlife, particularly in tropical regions that harbor high biodiversity yet remain vulnerable to environmental pressures. This study aims to examine the impacts of climate change on the distribution, phenology, behavior, and physiological responses of wildlife through a literature review of 23 scientific articles published between 2015 and 2025. The findings indicate that species with narrow habitat ranges and high sensitivity to temperature are especially vulnerable to climate change, particularly when compounded by anthropogenic disturbances such as deforestation and habitat fragmentation. Various impacts of climate change have been identified in tropical wildlife. Montane forest-endemic birds in the Andes have shifted to higher elevations due to rising temperatures, while Southeast Asian amphibians are threatened by declining microhabitat humidity. Changes in reproductive rhythms are evident in African wild dogs (Lycaon pictus), which have experienced shifts in their birthing seasons. In addition, increased nocturnal activity has been observed in large mammals in Africa and Asia as a response to thermal stress. Adaptive conservation strategies discussed include the establishment of ecological corridors, habitat restoration, and species distribution modeling. A science-based conservation approach is essential to address future ecological challenges.

ABSTRAKPemanfaatan biodiversitas hutan mangrove dalam upaya menjaga ketahanan pangan masyarakat pesisir sangat penting untuk diketahui. Mengingat pengetahuan tradisional sudah menjadi aset sosial yang penting maka fungsinya dalam masyarakat sekitar hutan harus diidentifikasi dengan jelas. Identifikasi spesies flora dan fauna di ekosistem mangrove dapat diarahkan untuk meningkatkan potensi diversifikasi dalam penggunaannya khususnya bagi masyarakat pesisir yang hidup berdampingan dengan hutan mangrove. Penelitian ini bertujuan mengidentifikasi jenis flora dan fauna mangrove yang dimanfaatkan masyarakat serta bentuk kearifan lokal dalam menjaga ketahanan pangan di Desa Jaring Halus, Kabupaten Langkat. Data diperoleh melalui wawancara semi-terstruktur dengan 35 responden dan observasi lapangan terhadap vegetasi dan fauna mangrove. Hasil menunjukkan bahwa masyarakat memanfaatkan 14 jenis tumbuhan dan 15 jenis ikan dan udang sebagai sumber pangan dan bahan pengobatan. Kearifan lokal berupa tradisi Jamu Laut berperan penting dalam menjaga keberlanjutan ekosistem mangrove. Pemanfaatan mangrove lebih dominan untuk bahan bakar dan kayu bangunan dibanding pangan langsung. Pengetahuan lokal ini berpotensi mendukung pengembangan strategi ketahanan pangan berbasis ekosistem pesisir.Kata Kunci: Kearifan lokal, Mangrove, Pangan, Pemanfaatan, PesisirABSTRACTUnderstanding the use of mangrove forest biodiversity in maintaining food security in coastal communities is crucial. Given that traditional knowledge has become a significant social asset, its function within communities surrounding the forest must be clearly identified. Identification of flora and fauna species in the mangrove ecosystem can be directed towards increasing the potential for diversification, particularly for coastal communities living adjacent to mangrove forests. This study aims to identify the types of mangrove flora and fauna utilized by the community and the forms of local wisdom in maintaining food security in Jaring Halus Village, Langkat Regency. Data were obtained through semi-structured interviews with 35 respondents and field observations of mangrove vegetation and fauna. The results indicate that the community utilizes 14 plant species and 15 fish and shrimp species as food sources and medicinal ingredients. Local wisdom, the Jamu Laut tradition, plays a crucial role in maintaining the sustainability of the mangrove ecosystem. Mangroves are predominantly used for fuel and building wood rather than for direct food. This local knowledge has the potential to support the development of coastal ecosystem-based food security strategies.Keywords: Local wisdom, Mangrove, Food, Utilization, Coastal
