Selamat datang di <b> <?php echo $this->config->web_app_title(); ?>. </b>

Sistem ini berguna untuk menentukan lokasi hydrant yang tepat di Kota Medan

berdasarkan kriteria lokasi seperti Topografi, Penggunaan Lahan, Gegologi,

Hidrologi, dan Aksebilitas. Output dari sistem ini adalah nilai preverensi

lokasi yang dihitung dengan metode Simple Additive Weighting (SAW). Kecamatan kota Medan

yang memiliki nilai preverensi tertinggi merupakan lokasi yang terpilih sebagai

lokasi hydrant yang tepat yang akan ditampilkan (dihighlight) pada peta kota Medan.<p> </p>

Pengguna dapat menggunakan sistem ini dengan mengikuti prosedur berikut:

<ul>

Pilih Menu <b>Fire Hydrant Kota Medan.</b> </li>

<li>

Input nilai <b>Bobot Kriteria (Weight)</b> dan <b>Matrix Keputusan X (r<sub>ij</sub>),

</b> kemudian tekan tombol <b>proses.</b> </li>

<li>

Nilai preverensi setiap alternatif (lokasi) akan ditampilkan, yang selanjutnya

dapat divisualisasikan dalam bentuk peta dengan mengklik link <b>Tampilkan Peta.</b>

</li> </ul>
