Identifikasi Dan Potensi Gulma Di Bawah Tegakan Jati Unggul Nusantara (Jun) Di Kebun Percobaan Universitas Nusa Bangsa, Cogreg, Bogor

Abstract

Weed Identification and Potential under the Stands o Superior Teak Nusantara (JUN) in Experiment Garden of Universityof Nusa Bangsa, Cogreg, Bogor Weed is a plant that the presence is not desirable because it can reduce the results achieved by the plant production. Weeds is an important component in forest ecosystems that must be taken their role. Composition and diversity of weed will determine the forest structure that will ultimately affect the ecological function of the forest. The presence and diversity of weeds under JUN stands in the area of Nusa Bangsa University experimental garden in Cogreg areas need to be studied and identifie for its potential to be used and prevention as well. The method of analysis used in this study was the least squares method of 0,5 m x 0,5 m and made 10 sample plots under the stand of JUN. Weeds were identified by using the description book based on morphological characteristics, the type, amount and its potential as a medical plant. The results showed that there were 15 types of weeds under JUN stands, namely Oxalis barrelieri, Phyllanthus niruri, Nephrolepis biserata, Ageratum conyzoides, Borreria latifolia, Molineria longiflora, Murdanium nudiflora, Synedrella nodiflora, Acalypha indica L, Echinochloa crus – galli (L.) P. beauv, Commelina diffusa Burm, Asystasia sp. and Clibadium surinamense. Among all the types of weeds, Borreria latifolia were dominant.Keywords : Teak Superior Archipelago (JUN), weeds, identification, medicinal plants ABSTRAK Gulma merupakan tumbuhan yang kehadirannya tidak diinginkan karena dapat menurunkan hasil yang dicapai oleh tanaman produksi. Gulma merupakan komponen penting dalam ekosistem hutan yang harus diperhitungkan perannya. Komposisi dan keanekaragaman gulma ikut menentukan struktur hutan yang pada akhirnya akan berpengaruh pada fungsi ekologis hutan. Kehadiran dan keanekaragaman gulma di bawah tegakan JUN di areal kebun percobaan Universitas Nusa Bangsa di daerah Cogreg perlu dipelajari dan diidentifikasi untuk dimanfaatkan potensinya maupun untuk penanggulangan gulma. Metode analisis yang digunakan dalam penelitian ini adalah dengan metode kuadrat 0,5m x 0,5m dan dibuat 10 petak contoh di bawah tegakan JUN. Gulma diidentifikasi dengan menggunakan buku deskripsi berdasarkan ciri morfologi, jenis, jumlah serta potensinya sebagai tumbuhan obat. Hasil penelitian menunjukkan bahwa terdapat 15 jenis gulma di bawah tegakan JUN, yaitu Oxalis barrelieri, Phyllanthus niruri, Nephrolepis biserata, Ageratum conyzoides, Borreria latifolia, Molineria longiflora, Murdanium nudiflora, Synedrella nodiflora, Acalypha indica L, Echinochloa crus-galli (L.) P. Beauv, Commelina diffusa Burm, Asystasia,sp,dan Clibadium surinamense. Diantara semua jenis gulma tersebut, yang mendominasi adalah Borreria latifolia.Kata Kunci: Jati Unggul Nusantara (JUN), gulma, identifikasi, tanaman obat

Respon gulma dan tanaman akasia terhadap aplikasi herbisida pra tumbuh

“…Gulma adalah salah satu indikator yang sangat penting dalam proses budidaya meskipun pengaruh yang disebabkan oleh gulma tidak secara langsung terlihat dan relatif berjalan lambat. Namum secara keseluruhan kerugian yang diciptakan sangat besar karena untuk mencukupi kebutuhan hara tanaman, sinar matahari, air, ruang tumbuh dan udara, gulma dapat berkompetisi dengan baik terhadap tanaman lain (Widhyastini et al, 2012).…”

The Existence of Undergrowth at Forest Garden Stands in Grand Forest Park, Lampung Province

“…Loss of undergrowth can occur due to the clearing of plants which are understood by farmers as weeds at the beginning of the tree planting process. Indeed, undergrowth can become weeds at the start of tree planting, but of course, the control must be as friendly as possible because the composition and diversity of undergrowth or weeds also determine the structure of the forest and affect the ecological function of the forest (Widhyastini et al, 2012).…”

“…Hilwan et al (2013) stated that the number of understorey species under pure plantation forest stands is generally 22 species with a total of 12 families. Understorey plants under mangium forest stand are 21 species (Goreti et al, 2021), under teak forest stands there are 15 species with 10 families, under superior teak forest stands there are 15 species of undergrowth (Widhyastini et al, 2012), in conservation forest there are 32 species of undergrowth with 21 families (Norris et al, 2020). It appears that the diversity of understorey species varies in different compositions of the tree species that make up the stand.…”

“…Of the 38 species of undergrowth, 57.89% (22 species) were medicinal plants and 13.16% (5 species) had the potential as raw material for vegetable pesticides (Table 1). & Susanto, 1992;Indriyanto & Harianto, 2004;Soepardi, 1964;Sutomo & Fardila, 2013;Widhyastini et al, 2012). *= endangered plants (Hamid 1987).…”
