“…According to [11], the presence of the roots of vegetation will create space that can be filled by water and strengthen soil aggregates. [5] said that organic matter levels will increase if the closure of the crown is tighter. This will encourage the activity of organisms on the soil surface, such as ants, worms, ureters, and other insects that form soil macropores.…”

The Jasinga Silviculture Teaching Industry (JSTI) area is a research forest with ecosystem conditions that have yet to be widely known. Research on the local ecosystem is needed, especially regarding vegetation, soil, and the hydrological cycle. Vegetation densities in the JSTI area are uneven, which affects groundwater absorption (infiltration rate). This study aimed to identify the infiltration rate and soil physical properties at different vegetation densities. The research plot was determined through purposive sampling techniques based on the level of vegetation density. The research methods carried out were analysis of vegetation density and composition, identification of soil physical properties (such as organic matter content, bulk density, porosity, and moisture content), measuring field infiltration rates using a double-ring infiltrometer, and analyzed the Spearman correlation. The results showed that dense vegetation has the highest score of organic matter content (> 4%), the bulk density is moderate, the porous category dominates the porosity, and the water content and infiltration rate were greater than sparse vegetation plots. Therefore, it is recommended to carry out planting activities at sparse vegetation density in the JSTI area.

“…Besides reducing the intensity of sunlight and maintaining temperature, lamtoro functions as a source of organic matter (Dahang and Munthe 2020). According to Bachtiar and Ura (2017), lamtoro provides versatile benefits, including fodder, intercrops, and wind barriers. Therefore, lamtoro is suitable for the Gayo coffee agroforestry system in Mude Nosar Village with windy and sloping area conditions.…”

Gayo coffee has many benefits in terms of the environment, economy, and socio-cultural aspects, especially for the Gayo tribe. Recently, Gayo coffee has been the main commodity for the plant cultivation of the Gayo tribe, including the Mude Nosar as local farmers. One of the ways to cultivate Gayo coffee is through an agroforestry system. However, limited reports on the tree species composition and its management in Gayo coffee-based agroforestry needs to be explored. This study aims i) to identify the tree species composition and structure, as well as 2) to analyze the management of Gayo coffee-based agroforestry system in Mude Nosar Village. The study method used plot establishment for vegetation analysis, and interviewed the Gayo coffee farmers. The results showed that the number of tree species at all growth stages was 26 species. The highest Important Value Index (IVI) at the understory and sapling level in order was rumput kerbau (Paspalum conjugatum) and Gayo coffee (Coffea arabica), while at the seedling, pole, and tree levels were dominated by lamtoro (Leucaena leucocephala). The local farmers often use lamtoro as a shade tree for Gayo coffee in agroforestry system. The species diversity index (H') showed low values at all growth levels, except for understory plants with moderate values. The horizontal structure of the tree stand showed an inverted J curve, meaning that the regeneration rate is normal. The vertical structure of the tree stand belongs to strata C and D. The local farmers have applied good Gayo coffee management practices through an agroforestry system including land and seed preparation, planting, maintenance, and harvesting techniques. Coffee seeds and seedlings are from natural regeneration. Plant maintenance techniques are carried out by weeding, pruning, organic fertilization, and controlling pests and diseases. The harvest coffee season is generally twice a year. The management of Gayo coffee using an agroforestry system impacts the ecological, economic, and social aspects.

“…Aren (Arenga pinnata) merupakan salah satu jenis tanaman yang mempunyai berbagai macam fungsi karena hampir seluruh bagiannya dapat digunakan. Aren dapat digunakan sebagai bahan baku untuk berbagai macam pangan, kerajinan tangan, peralatan serta perlengkapan rumah tangga, aren juga berfungsi sebagai tumbuhan konservasi (Bachtiar et al 2020), serta endosperm biji biasanya dikonsumsi sebagai bahan makanan maupun minuman (Rizki et al,2011).…”

“…Pematahan secara fisik dilakukan dengan pelukaan benih dekat embrio dan digosok dengan kertas amplas atau pasir. Menutut Polhauspessy, 2014; (Bachtiar et al 2020), hormone giberelin (GA) dapat mematahkan dormansi pada kulit biji dan mempercepat perkecambahan. Menurut (Saragih et al, 2019), cendawan endofit dapat memacu pertumbuhan tanaman dengan menghasilkan berbagai substansi hormon yang berbeda terhadap pertumbuhan tanaman.…”

Salah satu kendala dalam penyediaan bibit aren adalah dormansi aren dan pertumbuhan bibit yang membutuhkan waktu lama. Penelitian ini bertujuan untuk mengetahui jenis dan dosis cendawan endofit yang dapat mempercepat pertumbuhan bibit aren. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 2 perlakuan yaitu jenis cendawan endofit dan dosis cendawan endofit. Jenis cendawan endofit terdiri dari 3 taraf yaitu : isolat 1 (C1), isolat 2 (C2), dan isolat 3 (C3). Dosis cendawan terdiri dari 3 taraf yaitu: 5 gr (D1), 10 gr (D2), dan 15 gr (D3). Parameter yang diamati adalah panjang apokol (cm), munculnya tunas (hari), tinggi tanaman (cm), lebar daun (cm), panjang daun (cm), panjang akar (cm), bobot segar tanaman (gr), bobot segar akar (gr), bobot kering tanaman (gr), bobot kering akar (gr). Hasil penelitian menunjukkan jenis cendawan endofit isolat 1 (C1) cenderung memperlihatkan hasil terbaik pada parameter pengamatan munculnya tunas, panjang akar, panjang daun, bobot segar tanaman, bobot segar akar, bobot segar daun dan bobot kering akar. Dosis cendawan 5 g (D1) cenderung memperlihatkan hasil terbaik pada parameter pengamatan munculnya tunas, tinggi tanaman, lebar daun, panjang akar, bobot segar tanaman, bobot segar akar, bobot segar daun, dan bobot kering akar. Perlakuan jenis cendawan isolat 1 dengan dosis 5 g (C1D1) cenderung memperlihatkan hasil terbaik pada paremeter munculnya tunas dengan nilai rata-rata 31,3 hari, panjang akar dengan nilai rata-rata 22,7 cm, bobot segar tanaman dengan rata-rata 5,6 g, bobot segar daun dengan nilai rata-rata 1,2 g dan bobot segar akar dengan rata-rata 0,9 g.
