PEMILIHAN ALTERNATIF PERBAIKAN LERENG MELALUI PENDEKATAN “VALUE ENGINEERING”

Abstract

Slope failures and rockfall present significant hazards, including damage to retaining walls, highway infrastructure, blocking of drainages, and loss of bridges infrastructures. There is a need decision support frameworks based on geotechnical asset management principles for effective slope remedy procedure. This research objectives are to; (i) identification the steep slopes prone to rockfall/erosion along Lintas Tengah Sumatra from Pekanbaru (Riau Province) – Solok (West Suatra Province) via “Jalur Lintas Tengah Sumatra highway” encompassing 260 Km; and (ii) developing technical approach to remedy the slopes and (iii) establishing procedure in prioritizing slopes remedy based on value engineering technique. This research identified 65 prone to erosion and rockfall events. Approximately, 15 slopes were identified as high-risk slopes with RHRS scores of >300 points. According to value engineering approach, technical and economical aspects shuld be put into consideration in order to address issues of highway safety in a systematic procedure as well as efficient in use of limited budgets. Value engineering approach may suggest to remedy slopes within this road section at the following order.
