Mitigasi Longsor Berbasis Komunitas melalui Penerapan Metode Bioengineering Rumput Vetiver di Desa Petir

Abstract

Petir Village, Dramaga District, Bogor Regency, is one of the areas with a high level of landslide susceptibility. The steep topography, high rainfall, and history of landslide incidents that have caused casualties indicate the need for effective and sustainable mitigation efforts. This community service activity aims to strengthen community-based landslide mitigation through the application of the soil bioengineering method using vetiver grass (Vetiveria zizanioides). The program was conducted from June to October 2025 and consisted of four main stages: slope gradient measurement, landslide and bioengineering method socialization, vetiver planting, and identification of hazard-prone areas. Measurements in RW 03 and RW 04 identified slope gradients ranging from 17.7° to 35°, which are considered suitable for vetiver planting according to the PUPR Technical Guidelines (2012). Two points in RW 03 and RW 04 were prioritized for vetiver planting due to their proximity to residential areas. The results show that vegetation-based bioengineering methods can be effectively applied in the area. In addition to forming vegetative slope reinforcements, this activity also enhanced community capacity in understanding and implementing environmentally friendly disaster mitigation practices.
