Abstract

Urban drainage systems frequently experience performance degradation due to sedimentation and increased domestic wastewater, leading to inundation in residential areas. This study aims to evaluate the causes of inundation and sedimentation in the drainage system on Jalan Makmur Hutan, Medan Tembung District, Medan City. Primary data were obtained from seven observation segments through direct field measurements, including channel dimensions and sediment thickness, while secondary data consisted of 11-year rainfall records (2013–2023) from the Deli Serdang Climatology Station and population data for the same period. Hydrological analysis was conducted using the Log Pearson Type III distribution method to estimate design flood discharges for various return periods, and population projections for 2, 5, 10, 25, and 100 years were calculated using arithmetic, geometric, exponential, linear regression, and least square methods to estimate domestic wastewater discharge. The results showed that the average sediment thickness reached 0.27 m, reducing channel capacity by 29.7%, while the 5-year return period flood discharge was 6.34 m³/s. These findings indicate that sedimentation is the primary factor contributing to reduced drainage performance and frequent inundation in the study area. Therefore, regular channel normalization, routine maintenance, and integrated domestic wastewater management are essential to improve drainage performance and prevent future flooding.

Abstract

The implementation of an Occupational Safety, Health, and Environment Management System (OHSMS/SMK3L) is a crucial aspect in ensuring worker safety on high-rise construction projects. This study aims to identify risky work activities, evaluate the use of Personal Protective Equipment (PPE), and assess the implementation of safety facilities on a 16-story hospital construction project in Medan. The method used was direct field observation during a three-month internship, focusing on structural work. The study results indicate various high-risk activities, including working at heights, the use of heavy equipment, electrical installations, and welding and cutting. Furthermore, several hazardous work areas were identified, such as project traffic lanes, narrow spaces, and slippery work surfaces. The use of PPE, including safety helmets, safety shoes, reflective vests, gloves, masks, and body harnesses, was generally implemented. However, discrepancies were found in the use of PPE, both in terms of completeness and standards. Safety facilities such as K3 signs, evacuation routes, fire extinguishers, and first aid kits were available, but still require improvement in quantity and placement. The conclusion of this study indicates that the implementation of SMK3L in the 16-story hospital construction project in Medan has been quite successful, but still requires improvements in supervision, worker compliance, and compliance with occupational safety standards. Optimizing the implementation of SMK3L is expected to minimize the risk of workplace accidents and create a safe, healthy, and productive work environment.
