The more dense and crowded vehicles in the city of Pekanbaru increasingly comparable to road widening by the government. As a result, traffic jams at every intersection, continue to threaten. On some roads like Soekarno Hatta street and Riau street, almost every morning and evening always happen a long traffic jam. This is unavoidable because of the road conditions can not accommodate the num…
Pile threaded (Screw Pile) is one alternative foundation that can be used to provide a good carrying capacity on peat soil, to replace the use of wood pile. This study uses Screw Pile foundations with Helical Pile on a full scale, where there are 12 models of Helical Pile foundations with variations in the distance, number and diameter of the Helixs. Each model of the foundations is given axial…

This final project discusses the generalization of the quadrature rule and its error bound M. The error bound satisfies the error inequality |Rn| ≤ M which depends on a parameter ∈ [0; 1] where Rn indicates quadrature rule error. If the parameter is replaced by a specific number, we obtain a special shape of the error inequality for midpoint, trapezoidal and Simpson rule which their…
