ABSTRACT

The bridge is a means of connecting between places separated by the river, the

bridge construction project aims to mmemperlancar path of the economy,

development and connecting lines between the place or region .. In this paper the

authors designed sustu system capable of supporting decisions that determine the

structure of the soil to membangu bridge. Applications built a web-based

applications using the programming language PHP and using MySQL databse. The

method used in this application is Analytichal Hierarchy Process (AHP). This

method is a method known as weighted summation method used to find the optimal

alternative of a number of alternatives with the following criteria: soil structure,

layout area, bridge type, soil type, the type of foundation. then also requires the

decision matrix normalization process to a scale which can be compared with all the

ratings of existing alternatives so as to determine the feasibility of building a bridge

that is based on the structure of the soil.

ABSTRAK

Jembatan adalah suatu sarana penghubung antar tempat yang terpisah oleh

sungai, proyek pembangunan jembatan bertujuan untuk mmemperlancar jalur

perekonomian, pembangunan dan jalur penghubung antar tempat atau wilayah.. Pada

skripsi ini penulis merancang sustu sistem Pendukung keputusan yang mampu

menentukan struktur tanah untuk membangu jembatan. Aplikasi yang dibangun

merupakan aplikasi berbasis web dengan menggunakan bahasa pemrograman php

dan menggunakan databse MySQL. Metode yang digunakan dalam aplikasi ini adalah

Analytichal Hierarchy Process(AHP). Metode ini merupakan metode yang dikenal

dengan metode penjumlahan berbobot yang digunakan untuk mencari alternatif

optimal dari sejumlah alternatif dengan kriteria-kriteria sebagai berikut: struktur

tanah, letak daerah, jenis jembatan, jenis tanah, jenis pondasi. kemudian juga

membutuhkan proses normalisasi matriks keputusan ke suatu skala yang dapat

diperbandingkan dengan semua rating alternatif yang ada sehingga dapat

menentukan kelayakan bangunan jembatan yang berdasarkan struktur tanah.

Kata kunci :jembatan, proyek, Web, Sistem, Analytichal Hierarchy Process(AHP),
