Abstract

Abstrak. Ketergantungan manusia terhadap lahan sangat terlihat nyata dengan adanya perubahan fungsi lahan. Perubahan fungsi lahan juga berdampak terhadap tingkat biodiversitas tumbuhan. Studi ini mempelajari tingkat biodiversitas dan kelimpahan tumbuhan di tiga lokasi yang berbeda yaitu lahan konservasi pinus/perkebunan kopi, lahan persawahan dan lahan pemukiman. Ketiga lahan tersebut berada di Daerah Aliran Sungai (DAS) Cilaja yaitu di Desa Giri Mekar dan Desa Sindanglaya Kabupaten Bandung. Dalam penelitian ini dilakukan metode sampling struktur komunitas vegetasi untuk mengetahui komposisi, struktur dan jenis vegetasi serta perbedaan komunitas di tiga titik lokasi tersebut. Untuk analisis kuantitatif digunakan metode kuadran. Hasil penelitian menunjukkan bahwa lahan pemukiman desa lebih beragam dibandingkan dengan lahan sawah dan lahan perkebunan kopi. Dapat disimpulkan secara umum bahwa keterlibatan dalam mengelola lahan dapat merubah komunitas, tingkat keanekaragaman dan dominansi tumbuhan.Kata kunci : DAS, tingkat biodiversitas, metode sampling struktur komunitas vegetasi Abstract. Human dependence on land is very evident with the change in land use. Changes in land use also have an impact on the level of plant biodiversity. The study followed the level of biodiversity and abundance of plants in three different locations namely conservation land pine / coffee plantations, rice fields and residential land. The third land is located in the Watershed (DAS) Cilaja is in the village of Giri Mekar and Rural Sindanglaya Bandung regency. In this research, community structure vegetation sampling methods to determine the composition, structure and type of vegetation and the three-point difference in the communities that location. For quantitative analysis used kuadran method. The results showed that the rural residential land is more diverse than the wetland and coffee plantation. In general it can be concluded that involvement in land management can change the community, the level of diversity and dominance of plants.Keywords : DAS, level of biodiversity, community structure vegetation sampling methods

Abstract

This research had been conducted in the forest area around the Gunung Sa-lak Geothermal Power Plant of PT. PLN Indonesia Power. Plant diversity data in the geothermal power plant area had yet to be fully available. This study aimed to analyze the composition and structure of vegetation in the conservation forest area around the Gunung Salak Geothermal Power Plant unit. This study used a quadrat plot with a purposive sampling method. We sampled 873 individuals from 56 families of 110 species, consisting of native and introduced species. Some introduced flora species that have the potential to become invasive include Calliandra houstoniana, Asystasia gangetica, Bellucia pentamera, Miconia crenata, Maesopsis eminii, and Solanum torvum. The families with the highest number of species at each growth level were Fagaceae (tree), Fagaceae (pole), Arecaceae and Moraceae (sapling), also Acanthaceae, Arecaceae, Melastomataceae, and Poaceae in the understory. Several species of plant at the site are listed as Endangered (EN) based on the IUCN Red List, including Alpinia scabra, Castanopsis argentea, and Dipterocarpus hasseltii. These endangered plants are expected to become priority for conservation strategies and action plans. The Important Value Index (IVI) analysis shows different values at each growth stage. The highest IVI at the seedling and herb was Selaginella plana (29.74), the sapling was Macaranga triloba (20.59), the pole was Ficus fistulosa (43.27), and the tree was Schima wallichii (54.90). The value of the Shannon-Wiener (H') diversity index was 3.784, which indicates that the level of diversity is high.
