ABSTRACT This study aims to analyze hydrometric parameters in the Air Hitam River by comparing two commonly used measurement methods: the float method and the current meter method. Both methods are employed to measure flow discharge and water velocity along the river, which exhibits variations in flow due to natural factors and human activities. The float method tracks the time taken by a floa…
ABSTRACT This research analyzes water discharge with variations in flow velocity measurements at Sail River, Bukit Raya District, Pekanbaru City. Water discharge is a crucial parameter in hydrology, playing a significant role in water resource management, flood mitigation, and infrastructure planning. The study aims to determine the water discharge value based on flow velocity measurement meth…
ABSTRACT The Tangkerang River in Pekanbaru City frequently experiences flooding due to high rainfall that exceeds the river’s capacity. This study aims to design a retention pond (embung) as an alternative flood control measure to reduce the peak discharge of the river flow. Hydrological analysis was conducted using the Nakayasu Synthetic Unit Hydrograph (HSS) method with rainfall data f…
ABSTRACT The construction sector is one of the sectors with the highest work accident rates in Indonesia. To reduce the number of work accidents, the government issued Minister of PUPR Regulation No. 10 of 2021 concerning the Construction Safety Management System (SMKK). This study aims to analyze the implementation of SMKK in the Brain and Heart Hospital construction project in Pekanbaru…
ABSTRACT The CWR-01 AKSI ADB UNRI Physical Construction Project, specifically the Health Studies Complex Lecture Building, recorded a progress of 70,381% by the end of October 2023. However, according to the initial plan, the project should have reached 100%, resulting in a deviation of 29,618%. Therefore, it is necessary to identify the risks associated with the delay. This study aims to iden…
ABSTRACT The PT. X Palm Oil Mill is one of the palm oil producers in Riau. In its oil processing activities, this factory emits NO2, SO2 and Particulate emissions from the boiler chimney, furnace, and generator. In order to prevent the impact of these emissions, dispersion modeling needs to be carried out using the AERMOD View application consisting of AERMET and AERMAP. The purpose of thi…
