| dc.description.abstract | Drainage construction projects in urban areas such as Medan City are highly
complex, as they not only concern occupational safety but also have direct impacts
on the surrounding community and infrastructure. This study aims to identify
potential hazards in the U-Ditch drainage project activities, assess the associated
risks, and formulate mitigation strategies based on the Environmental
Occupational Safety and Health Management System (SMK3L) using the Hazard
Identification, Risk Assessment, and Risk Control (HIRARC) method. Data
collection was carried out through field observations at three project sites: Jl. Ir.
Juanda, Jl. Putri Merak Jingga, and Jl. Sunggal, distribution of questionnaires to
30 respondents consisting of workers and community members, and interviews with
10 drainage construction practitioners. The results of the study identified 22 hazard
variables, with six dominant risks as follows: infrastructure damage (V22) with a
risk value of 11 (16%), road function disruption (V21) with a risk value of 9 (12%),
disruption of underground utilities (V7) with a risk value of 10 (14%), dust exposure
(V17) with a risk value of 7 (10%), landslides due to excavation (V6) with a risk
value of 6 (9%), and environmental pollution (V18) with a risk value of 6 (9%).
Mitigation strategies focused on these six dominant risks through rapid
infrastructure repair, coordination between relevant agencies, implementation of a
traffic management plan, pre-construction surveys, and regular watering of the
work area. The application of the HIRARC method proved effective in providing a
quantitative risk assessment and generating practical mitigation strategies to
enhance workplace safety and minimize the social and environmental impacts of
urban drainage projects. | en_US |
