The conversion of land that occurred in the upstream part of the weir into fish ponds and oil palm plantations as well as the irrigation network not being maintained resulted in a lot of damage to buildings and irrigation channels in the Paku River irrigation network which resulted in the water discharge being small, as a result, rice fields in the downstream areas experienced water sho…
Indonesia is a country that has a high earthquake potential because it is located in the Pacific Ring of Fire. The buildings that function for the public interest must be designed in such a way as to avoid collapse, so as to minimize the number of casualties. Therefore, this research takes a 6-story building with dilation that functions as an educational building. Educational buildings must…
In waterworks planning efforts, the hydrological component is very important. The main component in hydrology is rainfall data, rain stations that are tasked with recording rainfall data. To obtain quality hydrological data, it is necessary to evaluate the number of rain posts that are evenly distributed to represent the hydrological conditions of the area of influence. This study was c…
Indonesia is located in the meeting zone of three tectonic plates, namely the IndoAustralian plate, Eurasia, and the Pacific plate, besides that Indonesia is also located in the ring of fire, causing Indonesia to experience frequent earthquakes. Earthquakes can cause both material and non-material losses, one of which is damage to building structures. Analysis of earthquake-resistant str…

The construction of the Dumai roll-on roll-off (Ro-Ro) ferry port is intended to support the Master Plan of ASEAN Connectivity, as well as the Establishment of an ASEAN roll on-roll off shipping network and short-sea shipping which has been programmed by the government. …
Lightweight bricks are a mixture of cement, sand, water, and foam agent used as building materials for walls due to their lower density compared to conventional concrete bricks. This can reduce the structural load on multi-story buildings. However, the brittle nature of lightweight bricks results in low compressive strength. The addition of fly ash, which has pozzolanic properties, can stre…
Biological wastewater treatment processes using suspended systems have been widely used. The most common and widely used wastewater treatment system is the Activated Sludge Process. Sludge age, which isthe length of time sludge settles and accumulates in waste processing plants, is an important factor in the waste management process. Sludge settling ability can be determined by determining …
Before the erection of a building, Time Schedule is one of the main processes carried out to determine how long the project can be completed by outlining each work item starting with determining the number of workers, calculating the duration of the work, making a time schedule, calculating the weight of the work and making curve s . In this Final Project report, the author makes a time…
Road damage is one of the things that must be overcome at this time, one of which is found on the Garuda road in Pekanbaru city with an overall road length of 1,400 meters and a road width of 5 meters, making it inconvenient for motorists who pass the road so that repairs are needed on the road starting with knowing the types of damage that exist. The purpose of this study is to determi…
Project management is an effort to use limited resources efficiently, effectively and on time in completing scheduled and planned projects. One of them can be applied in the time schedule planning project for a 2-story building for a motorbike dealer on Jalan Ratu Sima, Dumai City. With a building area of 480 m2, to prevent delays in work, project scheduling is required to determine the…
Indonesia is a region that frequently experiences earthquakes. Because the risk of earthquakes is high in Indonesia, innovation is needed to prevent and reduce the impacts caused by these natural disasters. One solution that can be implemented is to strengthen the existing building structure by providing external confinement to the concrete. Cable ties were chosen as the material for ex…
Time Schedule is the allocation of time available to carry out each job in order to complete a project to achieve optimal results by considering the existing limitations, while planning is a step in project management that tries to lay the foundation of goals and objectives while preparing all the technical and administrative programs so that it can be implemented. The problem presented…
Drainage is a facility for controlling air quality in relation to salinity, as well as ways to overcome the effects of excess water.
