The tropical forest has a unique feature. Its biological and ecological diversity relies on a very complex and interrelated system. Managing the forest sustainably required a wide application in multiple scientific disciplines. Jurnal Silva Tropika is a periodic scientific article and conceptual thinking of tropical forest management covering all aspects of forest planning, forest policy, forest resources utilization, forest ergonomics, forest ecology, forest inventory, silviculture, and management of regional ecosystems. Jurnal Silva Tropika also welcomes the topics that directly or indirectly support tropical forest management, e.g., economics, anthropology, social, and the environment.

Abstract

ABSTRACT Communities in Empat Lawang Regency, South Sumatra have implemented an agroforestry system. Bambang lanang (Magnolia champaca) is a local species and is mainly cultivated by the local communities in Empat Lawang Regency as a carpentry tree. However, the information of tree species composition and structure of Bambang lanang agroforestry system is still limited. This study aimed to analyze the tree species composition and structure in the Bambang lanang community forests. The method used was vegetation analysis in 4 villages with a total plot was 100 plots. The results showed that the agroforestry pattern was the most widely used pattern by Bambang lanang's farmers. The highest total plant species in the Bambang lanang community forest was found in Fajar Bakti Village (26 species). The highest number of species at the level of seedlings, saplings, poles, and trees in order were found in the villages of Muara Pinang (17 species), Paiker (17 species), Muara Pinang (12 species), and Paiker (20 species). The dominant plant species composition in the community forest is Bambang lanang, combined with Coffee (Coffea sp.), and Durian (Durio sp.). The agroforestry system contributes to the vegetation diversity.   Keywords: complex agroforestry, Sumatra, vegetation analysis, vegetation diversity   ABSTRAK Masyarakat di Kabupaten Empat Lawang, Sumatra Selatan telah mengimplementasi sebuah sistem agroforestry. Bambang lanang (Magnolia champaca) adalah jenis lokal dan umum dibudidayakan oleh masyarakat lokal di Kabupaten Empat Lawang sebagai kayu pertukangan. Oleh karenanya, informasi mengenai komposisi dan struktur jenis pohon pada sistem agroforestri Bambang lanang masih terbatas. Penelitian ini bertujuan untuk menganalisis komposisi dan struktur jenis pohon pada hutan masyarakat Bambang lanang. Metode yang digunakan adalah analisis vegetasi di 4 desa dengan total plot sebanyak 100 plot. Hasil penelitian menunjukkan pola agroforestri paling banyak digunakan oleh petani Bambang lanang. Jumlah spesies tertinggi ditemukan di hutan masyarakat Bambang lanang Desa Fajar Bakti (26 spesies). Jumlah spesies semai, pancang, tiang, dan pohon secara berurutan ditemukan di Desa Muara Pinang (17 spesies), Paiker (17 spesies), Muara Pinang (12 spesies), dan Paiker (20 spesies). Komposisi spesies tumbuhan dominan di hutan masyarakat adalah Bambang lanang yang dikombinasikan dengan kopi (Coffea sp.) dan durian (Durio sp.). Sistem agroforestri berkontribusi terhadap keanekaragaman vegetasi.   Kata kunci: agroforestri kompleks, analisis vegetasi, keanekaragaman vegetasi, Sumatra

Abstract

ABSTRACT Leuser Ecosystem Area (LEA) is an essential tropical forest ecosystem with an expansive approximately 2,6 Mha. Baseline data of tree species diversity and structure around LEA is limited, whereas vegetation cover as a portion of forest monitoring in GLNP still needs to be considered. The objectives of this study were 1) to estimate vegetation cover changes in LEA in 2016, 2020, and 2021 and 2) to analyze vegetation composition and structure in the natural forests (NF) of GLNP, as well as in the agroforestry system (AF) of Mude Nosar Village, Central Aceh Province where the parts of LEA. The methods used were the Normalized Different Vegetation Index (NDVI) for vegetation cover estimation and vegetation analysis in both locations. NDVI analysis resulted in 5 classes of vegetation cover in LEA, to be specific non-vegetation (class 1), very low dense vegetation (class 2), low dense vegetation (class 3), moderately dense vegetation (class 4), and highly dense vegetation (class 5). LEA vegetation cover in 2016, 2020, and 2021 is dominated by class 5 (highly dense vegetation). The most frequent seedling, sapling, pole, and tree species that grew in NF of GLNP in order were Geseng tanduk (Quercus sp.), Geseng minyak (Lithocarpus lucidus), Geseng pagar anak (Lithocarpus sp.), and Geseng batu (Lithocarpus conocarpus). The dominant species in AF were rumput kerbau (Paspalum conjugatum) at the understory and seedling level, coffee (Coffea arabica) at the sapling level, lamtoro (Leucaena leucocephala) at the pole and tree level. Tree structures in the NF of GLNP are reverse J-curves, while in AF of Mude Nosar Village are not fully reverse J-curves. The success of AF depends on considering tree species composition and structure, along with the specific needs and goals of the landowners. Consequently, enrichment planting in AF is necessary for biodiversity improvement.   Keywords: agroforestry, Gunung Leuser National Park, Mude Nosar Village, species composition, tree structure         ABSTRAK Kawasan Ekosistem Leuser (KEL) merupakan ekosistem hutan tropis yang penting dengan luas sekitar 2,6 juta hektar. Data dasar mengenai keanekaragaman dan struktur spesies pohon di sekitar KEL masih terbatas, sementara tutupan vegetasi sebagai bagian dari pemantauan hutan di Taman Nasional Gunung Leuser (TNGL) masih perlu diperhatikan. Tujuan penelitian ini adalah 1) memperkirakan perubahan tutupan vegetasi di KEL pada tahun 2016, 2020, dan 2021 serta 2) menganalisis komposisi dan struktur vegetasi di hutan alam (NF) TNGL serta sistem agroforestri (AF) di Desa Mude Nosar, Kabupaten Aceh Tengah, yang merupakan bagian dari KEL. Metode yang digunakan meliputi indeks vegetasi berbasis Normalized Difference Vegetation Index (NDVI) untuk estimasi tutupan vegetasi dan analisis vegetasi di kedua lokasi. Analisis NDVI menghasilkan lima kelas tutupan vegetasi di KEL, yaitu tanpa vegetasi (kelas 1), vegetasi sangat jarang (kelas 2), vegetasi jarang (kelas 3), vegetasi sedang (kelas 4), dan vegetasi sangat rapat (kelas 5). Tutupan vegetasi KEL pada tahun 2016, 2020, dan 2021 didominasi oleh kelas 5 (vegetasi sangat rapat). Spesies yang paling sering ditemukan pada tingkat semai, pancang, tiang, dan pohon di NF TNGL secara berurutan adalah geseng tanduk (Quercus sp.), geseng minyak (Lithocarpus lucidus), geseng pagar anak (Lithocarpus sp.), dan geseng batu (Lithocarpus conocarpus). Spesies dominan di AF adalah rumput kerbau (Paspalum conjugatum) pada tingkat bawah dan semai, kopi (Coffea arabica) pada tingkat pancang, serta lamtoro (Leucaena leucocephala) pada tingkat tiang dan pohon. Struktur pohon di NF TNGL mengikuti pola kurva J-terbalik, sementara di AF Desa Mude Nosar tidak sepenuhnya mengikuti pola J-terbalik. Keberhasilan AF bergantung pada pertimbangan komposisi dan struktur spesies pohon, serta kebutuhan dan tujuan pengelola lahan. Oleh karena itu, penanaman pengayaan dalam sistem AF diperlukan untuk meningkatkan keanekaragaman hayati.   Kata kunci: agroforestri, Desa Mude Nosar, komposisi spesies, struktur pohon, Taman Nasional Gunung Leuser
