Site class F is a profile of soil layers that are prone to failure or collapse due to earthquake loads such as liquefaction, highly sensitive clays, weak cemented soils, and highly organic clays that require specific geotechnical investigations and site-specific response analysis. If a structure has a shape or configuration not profitable to influence of earthquake forces, then the structur…
Tapung Kiri Sub river Basin is part of siak river basin which is categorized as a critical basin river and a flood prone area. The potential for flooding is caused by high rainfall in the middle, upstream and along basin river that have undergone land use changes. So it is necessary to do debit forecasting to find out when floods will occur in the future. There have been many hydrological mode…
Peatland fires are a recurring phenomenon and become a biggest problem in Indonesia. This problem was triggered because of conversion of peat swamp forest into agriculture and plantations, accompanied with the construction of drainage canals. The land use change with canalization can affect the hydrological function of the peat ecosystem which causes over drain and drought. One of the efforts t…
Pekanbaru City, which is the regional center of Riau, has three main functions, namely the center of government activities, the center of trade activities and the center of transportation activities. This research aims to analyze the level of intersection services based on the intersection traffic data, whether the degree of saturation has passed the DS = 0 threshold. , 75. If the DS value is> …
Increased air traffic at Sultan Thaha Syaifuddin Airport (Sultan Thaha Airport) located in Jambi City, Jambi Province and managed by PT. Angkasa Pura II occurs every year. PT. Angkasa Pura II plans to increase the ability of Sultan Thaha Airport to be able to serve wide-body aircraft by increasing the length and width of the runway with the current size of 2.220 meters long and 30 meters w…
Indonesia is located on earthquake-prone area and many building structures experience damaged and even collapse. To avoid damage on the building structures during the earthquakes several efforts have been suggested, one of the methods is the application of base isolation. The basic idea of this base isolation system is to isolate the propagation of vibrations caused by the earthquake from the g…
The research area is located in the right Kampar sub-watershed that crosses Riau and West Sumatra provinces. The result of the delineation process has formed 44 sub-watersheds with a total area of 447,221.10 ha. From the results of the study obtained 12 types of land closures, 5 types of land with a slope level of 0-25%. This study aims to analyze the effect of land cover changes on surface flo…
The accumulation of used tires in nature continues to increase due to the use of used tires which is still small so that the potential for environmental pollution is very high because used tires cannot be decomposed naturally. One of the industrial wastes that are considered hazardous to the environment is the fine form of coal combustion from a steam power plant called fly ash. Both of these w…
This study discusses the durability of conc rencete using PCC cement with a conc rencete quality plan of f'c renc 15 MPa, f'c renc 20 MPa and f'c renc 28 MPa through a treatment process using normal water for 28 days which is then immersed in a peat water environment with a pH ranging from 3.00-3.80 with an average pH of 3.42 for 120 days in Bengkalis Regency. The objective of this research is …
Time is a scale which is the duration of an event and the shape of the sand grains, is one of the factors that affect the technical properties of sand on shear strength, this needs to be considered so that the effect can be maximized for construction related to sand. The purpose of this study was to determine how to analyze the time required and the shape of the sand grains in analyzing the beh…
Rigid Pavement in Peat area requires high durability in order to make concrete could survive in surrounding environment without being damaged for a specified period of time. The research objective was to assess the durability of the concrete mixture of crumb rubber and fly ash with the quality of the 35 mpa fcr concrete plan which is soaked in peat water.

This thesis discusses the hypocycloid area starting by determining the auxiliary circle to calculate the hypocycloid area. Furthermore, to determine the hypocycloid area with the auxiliary circle, it is obtained from the reduction of the area of the circle forming the hypocycloid and the area of the auxiliary circle. Base on determining the area of hypocycloid, resulted that the area of hypocyc…
In a building construction, the column functions as a support for the loads from beams and slabs, to be transmitted to the subgrade through the foundation. The loads from these beams and plates are in the form of compressive axial loads and bending moments. Therefore, it can be defined that the column structure is a structure that supports axial loads with or without bending moments. An incline…
Rubber fibers from used tires can substitute for coarse aggregate, fine aggregate, and additives to mortar and concrete. Their elastic properties increased the flexibility and ductility of concrete, yet have not been widely used as high-value materials. This research used miniscule rubber powder with modifications of 0%, 2.5%, and 5% of cement weight from used tire processing in the tire r…
