Abstract. Fata YA, Hendrayanto, Erizal, Tarigan SD, Wibowo C. 2022. Vetiver root cohesion at different growth sites in Bogor, Indonesia. Biodiversitas 23: 1683-1692.The plant system, including the system of vetiver grass, plays a critical role enhancing soil cohesion, shear strength, and vegetated slope stability. Numerous studies on mechanical reinforcement grass-roots have been conducted, with majority focusing ground-planted good maintainedor naturally grown vetiver, while grass roots planted landslide areas various less maintenance is still uncommon.The purpose this study was to examine that grew had affected by landslides. samples were collected January 2021, age 8 months. from plants growing (a) bareland, (b) shrubland, (c) bushland. The tensile strength determined using Universal Testing Machine (UTM) capacity 3 tons, measurement accuracy load cell 1/10000. test conducted accordance ASTM D638-14 guidelines. Three repetitions performed representing length class 10 cm. results indicated influenced morphological architectural properties grass-roots. bushland exhibited higher density than bareland or shrubland. denser greater range lengths. Short cm most prevalent, them found near surface. depth, quantity roots.The (TR) tends get smaller longer roots, rootsgrew highestTR(15-59 MPa) relative their (9-37 shrubland (16-29 MPa). ratio fiber area (RAR) also deeper roots. Likewise, increasing caused (tR) (CR) which are function RAR. CR??of (0.015-0.275 kPa) relatively those (0.02-0.168 (0.002-0.028 same class, depth.

Nutritional and Antinutritional Components of Vetiver Grass (Chrysopogon zizanioides L. Roberty) at Different Stages of Growth
Vetiver grass was harvested at 4, 6 and 8-week old re-growth. The chemical composition and quantitative analyses of anti-nutritional components were determined. The result showed that dry matter and fiber content increased with age while crude protein, mineral content and anti-nutritional components reduced with age. It was concluded that age of re-growth significantly affect the nutrient and a...
