The use of fly ash waste as an ingredient in the manufacture of concrete is a step taken to reduce adverse impacts on the environment. Fly ash can be used as a substitute for cement in concrete, commonly called geopolymer concrete. Geopolymer concrete must use high temperature curing in order to accelerate polymerization and increase its strength. The addition of cement to geopolymer concrete, …
The utilization of fly ash waste as a material in concrete production is a step taken to reduce the adverse environmental impact. Geopolymer concrete is one of the applications of fly ash as a substitute binding material for cement in concrete. However, geopolymer concrete requires high-temperature curing to accelerate the polymerization reaction and enhance its strength. Geopolymer hybrid conc…
Sisingamangaraja XII airport is located in Tapanuli Utara, North Sumatra. This airport serves as the main gateway for tourists visiting Lake Toba. The increasing number of tourists visiting Lake Toba has led to a rise in the number of passengers at Bandar Udara Sisingamangaraja XII. In 2018, the airport handled 428,536 passengers, exceeding the existing passenger terminal capacity of 281,266 pa…
The intersection area of Jalan Garuda Sakti and the intersection of Jalan Tengku Bey Pekanbaru, is a center for education, commerce, offices, airports and also access roads outside the city. Traffic volumes that are not balanced with capacity cause deadlock at each intersection, resulting in congestion. Congestion at intersections can be overcome with yellow box junction markings. Minister of T…
The Reteh River is one of the rivers in Indragiri Hilir Regency, Riau Province, where during the rainy season, there is an increase in river discharge, so that river water overflows out of the river body. This overflow of water caused rice fields and residential areas to be flooded. To obtain flood discharge, several stages were carried out starting from rainfall consistency testing, frequency …
In general, the physiographic conditions of Pangkalan Kerinci District are sloping areas or lowlands and swampy areas. The lowlands in Pangkalan Kerinci District are generally influenced by the tides of the Kampar River, resulting in floods occurring at any time. The object of this research is the eastern part of Pangkalan Kerinci City which currently frequently experiences flooding when the ra…
Pangkalan Kerinci Barat Village is located in a lowland. However, it is unfortunate that the rapid development of the city has not been balanced with adequate infrastructure conditions so that in recent years the West Kerinci Base area has often been hit by floods. The rapid growth of the city is not balanced with adequate infrastructure, causing Pangkalan Kerinci Barat to often be hi…
As time goes by, population growth is increased rapidly in the Batang Kuranji Watershed area, followed by the need for natural resources and high land use which has an impact on land conversion or changes in land use, resulting in the potential for land erosion in the watershed area. Therefore, research was carried out to determine the rate of erosion and the level of erosion hazard that occurs…
Walking is a physical activity and is also the simplest mode of transportation. Walking is very effective because it can reach places that cannot be reached by motorized vehicles. Some students choose to live around campus so that access to campus can be reached easily and quickly. One option for students who are near campus is to walk. However, this is not supported by adequate pedestrian faci…
The use of clean water is a fundamental necessity for the population in Indonesia, where clean water is utilized for drinking, hydrology, irrigation, and various other purposes. Consequently, it plays a crucial role in the periodic infrastructure provision of clean water. One of the sources of water on Earth is derived from rainfall. In the planning of the development of existing water resource…
