Hutan mangrove merupakan ekosistem penting yang secara signifikan berkontribusi dalam mitigasi perubahan iklim, perlindungan pesisir, dan konservasi keanekaragaman hayati. Kajian literatur ini menganalisis peran hutan mangrove di Indonesia, dengan fokus pada kemampuan penyerapan karbon, jasa ekosistem, dan ancaman dari aktivitas manusia. Temuan menunjukkan bahwa mangrove menyerap karbon hingga lima kali lebih banyak dibandingkan hutan terestrial, dan berperan sebagai penyerap karbon yang sangat penting. Selain itu, mangrove juga berfungsi sebagai pelindung pantai dengan menstabilkan garis pantai, mengurangi erosi, dan melindungi masyarakat dari badai. Terlepas dari manfaat tersebut, hutan bakau di Indonesia mengalami degradasi yang signifikan akibat budidaya perikanan, pembangunan perkotaan, dan pembalakan liar. Upaya konservasi, termasuk kebijakan nasional dan inisiatif berbasis masyarakat, menunjukkan hasil yang menjanjikan tetapi membutuhkan penegakan hukum yang lebih kuat, pendanaan yang konsisten, dan keterlibatan masyarakat secara aktif. Studi ini menggarisbawahi perlunya pendekatan terpadu dari berbagai pemangku kepentingan untuk melestarikan hutan bakau sebagai aset penting dalam strategi ketahanan iklim Indonesia.

Kerentanan Indonesia terhadap bencana alam diperparah oleh degradasi lingkungan, sehingga mendorong pelaksanaan program rehabilitasi lahan dan hutan untuk mengurangi risiko bencana. Studi ini mengevaluasi efektivitas program-program tersebut dalam memitigasi bencana di berbagai wilayah dengan menggunakan pendekatan analisis komparatif. Data dari laporan program, wawancara, dan metrik lingkungan dikumpulkan dari beberapa inisiatif rehabilitasi terpilih di Jawa, Sumatera, Kalimantan, dan Sulawesi. Hasil penelitian menunjukkan bahwa keterlibatan masyarakat, diversifikasi pendanaan, strategi teknis yang sesuai dengan konteks, dan kolaborasi antarlembaga secara signifikan meningkatkan hasil program, yang mengarah pada pengurangan frekuensi dan tingkat keparahan bencana yang terukur. Namun, tantangan seperti keterbatasan pendanaan dan kendala pemeliharaan menghambat keberlanjutan program. Temuan ini menggarisbawahi pentingnya pendekatan adaptif yang berpusat pada masyarakat di daerah rawan bencana dan memberikan rekomendasi yang dapat ditindaklanjuti untuk memperkuat ketahanan bencana di Indonesia melalui restorasi ekologi.

This study explores the Community-Based Forest Management (CBFM) strategy as a means to maintain biodiversity in Papua, Indonesia. Using a qualitative approach, data were gathered through interviews with five key informants, including community leaders, local government officials, conservation NGO representatives, and researchers. Data analysis was conducted using NVivo software. The findings reveal that community participation, underpinned by indigenous practices, plays a critical role in forest conservation and biodiversity preservation. However, challenges such as limited resources, ambiguous land tenure systems, and external pressures hinder the effectiveness of these strategies. The integration of modern technology, such as GIS, was identified as a potential enhancer of CBFM outcomes, though capacity-building remains essential. This study underscores the importance of collaborative approaches, policy reforms, and capacity development in strengthening community-based conservation initiatives.

Tropical glaciers, such as those in Puncak Jaya, Papua, are among the most climate-sensitive ice masses on Earth, yet their small size, complex topography, and persistent cloud cover hinder accurate monitorin. Conventional threshold-based mapping methods, including the Normalized Difference Snow Index (NDSI), often misclassify debris-covered ice and bright bedrock, limiting their applicability in tropical mountain environments. This study develops and evaluates an integrated Linear Spectral Unmixing Analysis (LSUA)–Geographic Information System (GIS) methodology for high-fidelity mapping of glacier extent and surface composition in Puncak Jaya. Multispectral Landsat 8 OLI imagery was processed using LSUA to generate fractional abundance maps of clean ice, debris-covered ice, supraglacial water, and surrounding terrain. These outputs were integrated with Digital Elevation Models (DEMs) in a GIS framework for glacier area computation, elevation-based change detection, and spatial context analysis. Accuracy assessment using confusion matrices and Root Mean Square Error (RMSE) metrics against high-resolution reference imagery demonstrated that the LSUA–GIS workflow outperformed conventional NDSI mapping, particularly in detecting debris-covered ice, with an overall classification accuracy exceeding 90%. Results revealed continued glacier retreat, with the most significant ice loss occurring at elevations 4.884 MASL. The proposed workflow offers a reproducible and scalable approach for mapping small, fragmented tropical glaciers, providing critical data for climate impact assessment, hydrological planning, and long-term monitoring in remote mountain regions.

Kegiatan pengabdian kepada masyarakat ini dilaksanakan dalam bentuk Workshop Nasional Metodologi Penelitian dengan tema “Menyelami Konsep Dasar Pendekatan Kualitatif dan Kuantitatif” yang bertujuan untuk meningkatkan pemahaman peserta terhadap dasar-dasar metodologi penelitian. Permasalahan yang melatarbelakangi kegiatan ini adalah masih banyaknya mahasiswa, dosen, dan praktisi yang mengalami kesulitan dalam menentukan pendekatan penelitian yang tepat sesuai dengan permasalahan yang dikaji, sehingga berpengaruh pada kualitas penelitian yang dihasilkan. Pemahaman yang komprehensif mengenai metodologi penelitian menjadi hal yang sangat penting sebagai fondasi dalam proses penelitian ilmiah. Kegiatan ini dilaksanakan pada tanggal 1 Februari 2025 secara daring melalui aplikasi Zoom dan diikuti oleh 28 peserta dari berbagai kalangan. Metode pelaksanaan terdiri dari pemaparan materi oleh narasumber, sesi tanya jawab, dan diskusi interaktif yang membahas secara mendalam karakteristik, kelebihan, dan kekurangan pendekatan kualitatif dan kuantitatif. Hasil kegiatan menunjukkan bahwa peserta memperoleh pemahaman yang lebih baik mengenai perbedaan mendasar kedua pendekatan, serta mampu menentukan metode yang sesuai untuk penelitian mereka. Tingkat partisipasi yang tinggi selama diskusi juga menunjukkan adanya peningkatan ketertarikan dan kepercayaan diri peserta dalam merancang penelitian. Kegiatan ini penting untuk terus dilakukan sebagai upaya meningkatkan kualitas penelitian di berbagai bidang keilmuan.

This study examines the challenges of implementing Sustainable Forest Management (SFM) in Indonesia within the rapidly evolving context of globalization. Using a qualitative literature review of 10 Scopus-indexed articles, the analysis identifies key obstacles that hinder effective and sustainable forest governance. The findings reveal that institutional weaknesses—such as fragmented policies, weak law enforcement, and limited coordination among governmental agencies—remain central barriers. Economic pressures driven by global market demands for timber and agricultural commodities intensify deforestation risks and complicate the alignment between development goals and conservation priorities. Social challenges, including limited community participation, land tenure conflicts, and uneven distribution of benefits, further constrain the success of SFM initiatives. Additionally, environmental degradation, climate change impacts, and insufficient adoption of advanced monitoring technologies continue to undermine forest protection efforts. Global sustainability frameworks and certification schemes, while beneficial, introduce complex requirements that local stakeholders often struggle to meet. This study concludes that addressing SFM challenges in Indonesia requires strengthening institutional capacity, enhancing community empowerment, aligning economic incentives with conservation goals, and integrating advanced technologies to support evidence-based policymaking.
