Agroforestry system has been considered as one of the effective ways of the plantation for increasing a production and securing the environment as well as plays an important role in the social and economic development. Mindi development has been widely practiced in community forests but the agroforestry system is only limited to local knowledge obtained from old generation. This causes the people's forests to tend to be unable to survive due to the demands of the people's food needs. Arrowroot (Maranta arundinacea L.) had an important crop as a potential source of food and substitute for wheat flour and potential to be planted under Mindi trees (Melia azedarach L.) which had also potential as an alternative tree planting for the community forest. This research was aimed to 1) analyze the growth of Mindi trees and the productivity of arrowroot under mindi trees compared to monoculture system, 2) analyze the nutrient content of arrowroot under mindi trees compared to monoculture system. The experiment used a complete randomized design (CRD) with the agroforest under mindi trees and monoculture system as a factor. The result of growth in mindi showed that there is no significant difference in height, diameter, and canopy variable in agroforestry and monoculture plantation system while the root variable had significant difference among agroforestry and monoculture system. The physicochemical and nutrients content of arrowroot were diverse whereas there is no significant difference between the two system tested.Keywords: agroforestry, growth, productivity, fisikokimia, soil nutrient
Masyarakat suku gayo memiliki hubungan erat dengan alam dan lingkungan. Masyarakat memanfaatkan berbagai tumbuhan yang ada di sekitar dalam tradisi adat yang telah turun temurun dari para leluhur. Penelitian ini bertujuan untuk mengetahui spesies tumbuhan yang dimanfaatkan oleh masyarakat dalam upacara adat serta menjadi sumber tertulis bagi masyarakat terutama para generasi. Pengumpulan data dilakukan dengan survei lapangan, dokumentasi dan wawancara mendalam (in deft interview) dengan para tokoh adat, tokoh agama, tokoh orang tua dan tokoh masyarakat. Masyarakat mengenal tumbuhan adat yang digunakan dengan Dun kayu kul dan Dun kayu ucak, yang terdiri dari beberapa spesies tumbuhan dan beberapa upacara adat yang memiliki makna yang dipercaya oleh masyarakat suku Gayo. Jenis tumbuhan adat yang dimanfaatkan tidak bisa digantikan dengan jenis tumbuhan lain karena akan menghilangkan makna dan kesakralan pelaksanaan upacara adat.
Abstrak. Keanekaragaman Hayati atau Biodiversity merupakan variasi atau perbedaan bentuk-bentuk makhluk hidup, yang meliputi perbedaan-perbedaan pada tumbuhan, hewan dan mikroorganisme. Nilai INP merupakan salah satu indeks yang dihitung berdasarkan jumlah yang didapatkan untuk menentukan tingkat dominansi dari suatu komunitas. Penelitian ini bertujuan untuk mengetahui nilai INP dan jenis keanekaragaman hayati, yang dilakukan di Desa Leme Kecamatan Blangkejeren Kabupaten Gayo Lues. Pengambilan data yaitu dengan metode purvosive sampling dengan luas wilayah 10 ha yang diambil luas sample 0,5 ha dengan IS 5% sehingga terdapat jumlah 12 plot sample, masing-masing plot dengan luas 400 m2. Berdasarkan hasil penelitian di lapangan, keanekaragaman jenis tumbuhan yang terdapat di hutan pinus yaitu tumbuhan Pinus, Temung, Jambu Biji dan Mangga, dengan tingkat keanekaragaman lebih kecil dari 1 masuk dalam kategori rendah, sedangkan nilai INP menunjukan tumbuhan jenis Pinus lebih besar nilainya dibandingkan tumbuhan jenis lainnya, yaitu dengan nilai 277,13 dengan kategori sangat tinggi.Estimation of Biodiversity Analisis of Pine Forests in Leme Village Blangkejeren District Gayo LuesAbstract: Biodiversity is a variation or difference in the forms of living things, which includes differences in plants, animals and microorganisme. INP value is an index that is calculated based on the amount obtained to determine the level of dominance in a community. This study aims to determine the INP value and types of biodiversity. Which was carried out in Leme village Blangkejeren District Gayo Lues regency. Data collection is by purposive sampling method with an area of 10 ha which is taken with a sample area of 0,5 ha with an IS of 5% so that there are a total of 12 sample plots, each plot with an area of 400 m2. based on the results of research in the field, the diversity of plant species found in pine forests, namely pine, temung, guava and mango plants, with a diversity level of less than 1 is in the low category. While the INP value of 277,13 with a very high category.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
