Abstract

Water is a vital resource that supports various aspects of life, including domestic needs, agriculture, industry, and environmental conservation. The development of infrastructure such as dam plays a key role in maintaining the sustainability of water resources. So it is necessary to pay attention to hydrological analysis, lighthouse, and also stability of a weir. The aim of this research is to be able to understand and know how to plan weir by using existing technical data on weir designs as a guide and as a comparison parameter in this research. This research was carried out in Majene Regency, West Sulawesi Province during March to August 2024. The results of this research show that in general the hydraulic planning review for Kayuangin weir consists of a lighthouse height of 5 m, a weir width of 108 m, an effective width of the weir of 99,5 a deckzerk elevation of 26,59, a lighthouse elevation of 23,20, front floor elevation 17,95, and front floor length 20,60.

Abstract

The Jene'berang River Basin is one of the main river basins in South Sulawesi Province, which has a high level of sedimentation and landslide vulnerability due to a combination of factors, including steep topography, unstable soil types, high rainfall, and changes in land use. This study aims to analyze the effectiveness of applying pine vegetation-based bioengineering technology in sediment control in the Jene'berang-Jenelata watershed. The research method was conducted from January to June 2025 through field observations, spatial analysis using Geographic Information Systems and measurements of sediment landslide volumes at several variations of pine vegetation planting distances. The parameters analyzed included soil classification, land activity, slope gradient, rainfall, and sediment landslide volume. The results showed that the application of bioengineering had an effect on sediment control, with variations in vegetation planting distance affecting the volume of landslides that occurred. Wider planting distances showed higher sediment retention efficiency compared to very dense planting distances. The appropriate and integrated application of bioengineering technology with the physical characteristics of the watershed is expected to be a sustainable solution for sediment control and landslide mitigation in the Jene'berang watershed.
