Abstract

Kerusakan hutan mangrove di Desa Silo Baru menyebabkan terganggunya fungsi mangrove baik secara fisik, biologis, dan ekonomi. Upaya rehabilitasi dilakukan sebagai sebuah langkah perbaikan agar fungsi-fungsi tersebut dapat kembali berjalan sebagaimana mestinya. Selain itu, kegiatan rehabilitasi bisa memicu perubahan atau penambahan komposisi dan keanekaragaman jenis di suatu wilayah. Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman jenis vegetasi mangrove hasil rehabilitasi di Desa Silo Baru, Sumatera Utara. Pengambilan data dilakukan pada 4 lokasi rehabilitasi mangrove menggunakan metode transect line plot dengan jarak antar petak ukur adalah 55 m. Setiap petak ukur dilakukan pengamatan vegetasi dengan metode nested sampling menggunakan petak ukur 10x10 m untuk pohon, 5x5 m untuk pancang, dan 2x2 m untuk semai. Analisis dilakukan dengan menggunakan INP dan indeks diversitas Shannon. Hasil menunjukkan bahwa ditemukan 12 jenis vegetasi mangrove yang terdiri dari 10 mangrove mayor dan 2 mangrove minor. Jenis mangrove yang mendominasi pada setiap lokasi rehabilitasi berbeda-beda dan keanekaragaman jenis mangrove hasil rehabilitasi di Desa Silo Baru tergolong kriteria keanekaragaman rendah hingga sedang.

Abstract

Background. Mangrove ecosystems have increasingly been recognized as important components of disaster risk reduction (DRR), particularly in mitigating the impacts of coastal hazards such as tsunamis, storm surges, and coastal flooding. Alongside the growing influence of climate change adaptation and nature-based solutions, scholarly interest in mangroves has expanded across multiple disciplines. However, the overall development, thematic orientation, and existing gaps within mangrove-based DRR research remain insufficiently synthesized. The study’s objective was to examine the evolution, disciplinary structure, dominant themes, and underrepresented areas of global research on mangroves in the context of DRR. Materials and methods. This study employed a bibliometric approach to analyze peer-reviewed journal articles and review papers indexed in the Scopus database between 2000 and 2026. Descriptive analysis, keyword co-occurrence networks, thematic mapping, thematic evolution analysis, and geographic collaboration analysis were conducted using Biblioshiny and supporting analytical tools to identify publication trends, subject area distributions, core journals, thematic structures, and spatial research patterns. Results. The findings reveal a substantial increase in mangrove-based DRR research over time, particularly following major coastal disasters and during the recent climate-resilience era. The literature is dominated by environmental and earth sciences and primarily framed around ecological protection, ecosystem services, and hazard mitigation. In contrast, governance, preparedness, social vulnerability, and policy-oriented dimensions remain weakly represented. Thematic evolution indicates a shift toward climate-related and ecosystem-based approaches, alongside persistent conceptual gaps. Conclusions. This study concludes that while mangroves are well-established as ecological assets in DRR studies, their role as socio-ecological infrastructures remains underexplored. Advancing mangrove-based DRR requires greater integration of governance, preparedness, and social perspectives to enhance policy relevance and support sustainable coastal resilience.

Abstract

Mangrove forests are vital coastal ecosystems that sequester large amounts of carbon, helping mitigate climate change. Indonesia has the world’s largest mangrove area, including the Langsa Protected Mangrove Forest in Aceh, which holds high biodiversity and significant blue carbon potential. The Mangrove Forest Tourism Area in Langsa is one of the largest in Southeast Asia; therefore, estimating its carbon potential is essential to support Indonesia’s commitments to the Paris Agreement and carbon trading initiatives. This study aims to (1) identify tree species diversity in mangrove, and (2) estimate aboveground biomass, carbon stock, and carbon sequestration in the Langsa Mangrove Forest Tourism Area. A purposive sampling method was used for the initial plot, followed by systematic sampling. From 369.01 hectares of mangrove area, 19 plots were established with sizes of 10 m × 10 m for trees, 5 m × 5 m for saplings, and 2 m x 2 m for seedlings. Carbon stock estimation employed species-specific allometric equations. Out of 293 individual trees, four tree species, namely Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Ceriops tagal, were identified, with most ranging within 3.18–4.61 cm diameter classes. The highest aboveground biomass, carbon stock, and carbon sequestration were found in plot 19, at 27.66 ±13.18 tons/ha), 13.00 ±6.20 tons C/ha), and 47.67 ±22.71 tons CO₂/ha), respectively. These findings highlight the substantial blue carbon potential of the Langsa Mangrove Forest in a protected area, emphasizing its importance in regional conservation strategies.

Abstract

Cinnamon as a non-timber forest product plays a significant economic role in supporting rural livelihoods in Gayo Lues Regency, Aceh Province. This study analyzes the economic value contribution of cinnamon cultivated and utilized by communities in several villages of Kutapanjang District. The primary product utilized is cinnamon bark, while the stem is not commercially traded and is instead used as household fuelwood. The findings indicate that the average annual income derived from cinnamon bark reaches Rp26,557,283 per household, contributing 71% to total household income. In comparison, secondary livelihood activities contribute Rp2,213,106 or 29%. These results demonstrate that cinnamon functions as the dominant income source within the local agroforestry system. The aggregate economic structure reflects relatively stable returns, indicating resilience against short-term market fluctuations. The integration of household-based forest resource management and local economic activities highlights cinnamon’s strategic role in strengthening village economies. Therefore, cinnamon as a non-timber forest product represents a sustainable economic driver that supports rural development and forest-based livelihood systems in Gayo Lues Regency.
