Abstract

Sedimentation in drainage channels is one of the main factors that can reduce flow capacity and hydraulic performance. This study aims to analyze the effect of sedimentation levels on flow discharge in several drainage channel segments with different cross-sectional shapes, namely rectangular and trapezoidal, as well as varying channel dimensions. The data used include channel width, channel height, sediment thickness, and water surface elevation in each segment. Flow discharge is calculated using the Manning equation to determine the actual flow conditions. The results show that higher sedimentation levels significantly reduce flow discharge, particularly in segments with smaller channel dimensions. In addition, rectangular cross-sections with larger dimensions tend to provide better flow capacity compared to smaller trapezoidal sections. Therefore,     sedimentation plays an important role in influencing the performance of drainage systems.

Abstract

Analysis of Sedimentation Percentage and Its Impact on Flow Discharge in Trapezoidal and Rectangular Channel Sections. Sedimentation in drainage channels is a major cause of reduced capacity and flow effectiveness. This study aims to analyze the effect of sedimentation percentage on flow discharge in five segments of drainage channels with variations in cross-section types (rectangular and trapezoidal) and dimensions. The data used include top width, bottom width, channel height, sediment thickness, and water surface height in each segment. The analysis was conducted using Manning’s equation to calculate the actual flow discharge under existing conditions. The results show that the highest sedimentation levels occur in Segments 2 and 3, with percentages of 20.8% and actual discharges of 0.597 m³/s and 0.560 m³/s, respectively. Segment 1 with a trapezoidal section has 7.4% sedimentation and the smallest discharge of 0.0022 m³/s due to small channel dimensions. Segments 4 and 5 have sedimentation rates of 7.5% and 4.6% with actual discharges of 0.0278 m³/s and 0.0286 m³/s. It can be concluded that sedimentation significantly affects the reduction of flow discharge, and rectangular sections with adequate dimensions provide better flow capacity compared to trapezoidal sections with small dimensions.

Abstract

This study analyzes the implementation of the Occupational Health and Safety Management System (OHSMS/SMK3) at the Hotel XYZ construction project in Balige, Toba, North Sumatra. The project is a 16-story hotel building currently at the structural work stage (floors 6-8) at the time of observation. A qualitative observational method was used, carried out during a 3-month internship period. Data was collected through direct field observations covering risk activities, use of personal protective equipment (PPE), availability of K3 signs and facilities, as well as supervision and work procedures. The results show that high-risk activities such as working at height, heavy equipment operation, material lifting, welding, and electrical work were identified at the site. PPE consisting of safety helmets, reflective vests, safety shoes, work gloves, and full body harnesses were available; however, worker compliance in using PPE was still low. Several critical K3 facilities were not available, including K3 signs, assembly points, fire extinguishers (APAR), Lock Out-Tag Out (LOTO) systems, safety briefings, APD supervision, K3 SOPs, and K3 officers. These findings indicate that the SMK3 implementation at this project is still in the poor category based on the performance criteria of Ministerial Regulation PU No. 9 of 2008. Improvement recommendations include providing complete K3 facilities, implementing routine safety talks, strengthening supervision, and appointing competent K3 officers.

Abstract

Urban drainage systems play an important role in managing stormwater runoff in urban areas. Rapid urban development often reduces infiltration areas and increases surface runoff, which can lead to flooding and waterlogging in several locations. This study aims to analyze the performance of urban drainage systems and identify factors causing water inundation in urban areas. The research method used is a descriptive quantitative approach by evaluating drainage channels based on rainfall data, channel capacity, sedimentation conditions, and supporting environmental factors. Secondary data were collected from previous studies and hydrological analysis results. The analysis includes rainfall intensity calculation, runoff discharge estimation, and comparison with existing drainage channel capacity. The results show that several drainage channels are unable to accommodate the design discharge due to sedimentation, waste accumulation, and changes in land use. In addition, insufficient maintenance of drainage channels also contributes to the reduced performance of the drainage system. Therefore, improvements in drainage channel capacity, routine maintenance, and integrated urban drainage planning are needed to reduce flood risks in urban areas. The results of this study are expected to provide useful information for local governments in improving urban drainage management systems.

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.
