Abstract

The Industry revolution 4.0 has become a prominent topic of discussion, emphasizing the need to harness digital technology to enhance various aspects of human work, including the construction industry. In the field of construction, Building Information Modeling (BIM) has been widely adopted as a guiding framework for construction processes. Additionally, Augmented Reality (AR) technology has emerged as a powerful tool for bringing 3D models into the physical world. This research employs a qualitative approach, utilizing 3D design data of Pile Caps in the construction of the IKN Minister's Residence and Solo - Yogyakarta Toll Road Office. A total of 74 and 68 coordinate points were extracted from each design to analyze the discrepancies resulting from the implementation of AR technology. The findings reveal that both designs exhibited a margin of error of 0.6148648649 % for the IKN Minister's Residence and 0.6102941177 % for the Solo - Yogyakarta Toll Road Office, both of which fall below the 1% threshold for maximum allowable error.

Abstract

This research discusses efforts to revitalize the Batujai Reservoir in Central Lombok with a focus on sedimentation problems. Batujai Reservoir has a strategic role in meeting water needs in the surrounding area, but faces serious challenges due to significant sedimentation. In addition to assessing the effects of these changes on the reservoir's benefits—such as irrigation, flood control, and electricity production—this study intends to examine the effects of land use changes in the Dodokan Sub-Watershed Catchment Area (DTA) on the features and volume of sedimentation entering the reservoir. In addition, this study attempts to develop suggestions for efficient sedimentation management plans in order to increase the Batujai Reservoir's service life. Research methods include primary and secondary data collection, sedimentation modeling using the Water and Tillage/Sediment Delivery Model (WATEM/SEDEM), to evaluate the impact of sediment control structures such as check dams. Research variables include catchment area, population, annual rainfall, average daily evaporation, mainstay surface water availability, land surface erosion rate, sediment volume deposited in the reservoir, effective age of the Batujai Reservoir, and changes in land use in the Dodokan Sub-watershed. The results of this research will provide a better understanding of the main sources of sedimentation in the Batujai Reservoir and the impact of land use changes on the reservoir. It is hoped that the recommendations for sedimentation management strategies resulting from this research will help maintain reservoir storage capacity, which is important for meeting various water needs in the region.
