Abstract

A Retaining Wall (DPT) is a structural element designed to hold back soil and maintain land stability, particularly in hilly or landslide-prone areas. In Ubud, Bali, a region renowned for its cultural tourism and natural landscapes, retaining walls play a crucial role in ensuring land stability and infrastructure safety. The Parisudha Ubud, a guesthouse currently undergoing expansion, requires the construction of a DPT due to its sloping terrain and risk of soil displacement. However, the construction of DPTs often involves high costs, which can hinder project efficiency and timely completion. This study applies the Value Engineering (VE) approach as a method to optimize construction costs without compromising the structural integrity and function of the DPT. The research methodology includes field observations, technical data analysis, and cost simulations. Three alternatives were compared to the initial design: (1) Reinforced Concrete DPT, (2) Geotextile + Stone Gabions, and (3) Wire Gabion and Stones. The analysis results indicate that Alternative 3 is the most cost-efficient option, yielding savings of IDR 80,549,600. This alternative not only reduces costs but also aligns with sustainable tourism principles by using eco-friendly materials and minimizing construction waste. Therefore, the application of VE in this project offers tangible benefits in reducing costs while ensuring a more sustainable approach to infrastructure development for tourism.
