Abstract

Low back pain (LBP) is one of the most common health problems among office workers, especially those with long working hours and unergonomic sitting postures. Many work responsibilities must be completed so that the time to rest and return to work is uncertain. This study aims to analyze the relationship between work duration and work posture with NPB complaints in office workers and the factors that influence them. The method used is literature review by reviewing 15 journals that discuss the risk factors of NPD. The results of the analysis showed that work duration exceeding 8 hours and poor sitting posture had a significant correlation with an increased risk of NPD. In addition, several other factors contribute to the incidence of NCD, such as age, workload, and work attitude. Older workers are at higher risk of NBP due to reduced bone elasticity and muscle stability. Heavy workloads and long working hours cause muscle fatigue, which increases complaints of NBP. Unergonomic work attitudes, such as bending or sitting that are not ideal, also increase the risk of musculoskeletal disorders. Prevention can be done through the application of ergonomic principles and good working time management to reduce musculoskeletal risks.

Abstract

UAVs with RTK technology offer high-accuracy aerial mapping, with RTK Radio and RTK NTRIP as two correction methods affecting orthomosaic precision. While previous studies compared these methods in terrestrial surveys, their impact on UAV-based orthomosaics remains underexplored. This research evaluates and compares the accuracy of UAV-derived orthomosaics using RTK Radio and RTK NTRIP to provide practical guidance for optimal mapping applications. This research combined UAV RTK photogrammetry and GIS to produce high-precision aerial maps in two areas of Padang City with different topographies. Data were collected using DJI Mavic 3 Enterprise RTK with RTK Radio and RTK NTRIP techniques, supported by GCPs, BMs, and satellite imagery, then processed into orthomosaics for analysis. Accuracy was assessed using ICPs and statistical measures like RMSE to compare the spatial precision of both correction methods under varying terrain conditions. The results show a difference in mapping accuracy between RTK Radio and RTK NTRIP aerial photographs, with RTK Radio achieving 0.683 accuracy and 0.450 RMSE, while RTK NTRIP reached 0.563 accuracy and 0.371 RMSE. RTK Radio is more suitable for areas lacking CORS access but still requires GCP verification. RTK NTRIP performs better in urban areas with strong CORS networks. Combining both methods with adequate GCPs provides an effective solution for mapping in varied or densely vegetated terrains.
