This work studied slopes with different geometric situations. The purpose is to select types of soil for embankment construction stabilise the site by using nearby accessible filling materials. Then, PLAXIS-2D software was used including five (6) phases sequential calculation such as soil, structure, mesh generation, conditions flow and stage use Vetiver grass embakment stability reinforcement....

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, wit...

High-valued medicinal plants Achillea millefolium, Acorus calamus, Arnebia nobilis, Fumaria indica, Gymnema sylvestre, Origanum vulgare, Paeonia emodi, Peganum harmala, Psoralea corylifolia, Rauwolfia serpentina, and Vetiveria zizanioides were identified with the help of taxonomical markers and investigated for characterization and palynological studies. These parameters are used to analyze the...

Roots of Vetiveria zizanioides Nash (Mae Hae; Thai ecotype) planted in three different cultivation systems (normal soil, normal soil with added microbes and semi- hydroponically) were extracted using a simultaneous steam distillation and solvent extraction (SDE) apparatus. Yields of the essential oils obtained were 0.27, 0.18 and 0.06%, respectively. The separation profiles obtained by comprehe...
