SMART

Simple Multi Attribute Rating Technique (SMART) method for developing Decision Support System

Konfigurasi Metode SMART

Konfigurasi metode ini dapat dilihat pada Smart/config.json. Terdapat dua key yang harus dikonfigurasi, yaitu criteria dan predicate.

Contoh kasus:

Kriteria Penghasilan Orang Tua

Bobot: 20%.

Penghasilan	Nilai
≤ 1.500.000	100
1.500.001 - 2.000.000	80
2.000.001 - 2.500.000	60
≥ 2.500.001	40

Kriteria Tanggungan Orang Tua

Bobot: 10%.

Tanggungan	Nilai
≥ 4	100
3	80
2	60
1	40

Predikat

Range Nilai	Predikat
80 - 100	Layak
0 - 79	Tidak Layak

Sehingga config.json-nya akan terlihat seperti ini

{
  "criteria": [
    {
      "label": "Penghasilan Orang Tua",
      "name": "penghasilan_orang_tua",
      "weight": 20,
      "type": "range",
      "rules": [
        {
          "max": 1500000,
          "value": 100
        },
        {
          "max": 2000000,
          "min": 1500001,
          "value": 80
        },
        {
          "max": 2500000,
          "min": 2000001,
          "value": 60
        },
        {
          "min": 2500001,
          "value": 40
        }
      ]
    },
    {
      "label": "Tanggungan Orang Tua",
      "name": "tanggungan_orang_tua",
      "weight": 10,
      "type": "range",
      "rules": [
        {
          "min": 4,
          "value": 100
        },
        {
          "max": 3,
          "min": 3,
          "value": 80
        },
        {
          "max": 2,
          "min": 2,
          "value": 60
        },
        {
          "max": 1,
          "min": 1,
          "value": 40
        }
      ]
    }
  ],
  "predicates": [
    {
      "label": "Layak",
      "max": 100,
      "min": 80
    },
    {
      "label": "Tidak Layak",
      "max": 79,
      "min": 0
    }
  ]
}

Contoh Penggunaan

Lihat di index.php.

<?php
include_once 'Smart/Smart.php';

// instansiasi objek SMART
$smart = new Smart();

// beri data yang akan dihitung
$smart->fit(
  [
    'ipk' => 3.50,
    'prestasi_non_akademik' => 'Internasional',
    'penghasilan_orang_tua' => 1300000,
    'tanggungan_orang_tua' => 2
  ]
);

echo $smart->result() . '<br>'; // output: 88
echo $smart->predicate() . '<br>'; // output: Layak

Contoh Penggunaan dengan Framework Codeigniter

Copy-Paste folder Smart ke dalam application/libraries/.

<?php

class ContohController extends CI_Controller
{
  public function __construct()
  {
    parent::__construct();
  }
  
  public function index()
  {
    // instansiasi objek SMART
    $this->load->library("Smart/smart");

    // beri data yang akan dihitung
    $this->smart->fit(
      [
        'ipk' => 3.50,
        'prestasi_non_akademik' => 'Internasional',
        'penghasilan_orang_tua' => 1300000,
        'tanggungan_orang_tua' => 2
      ]
    );

    echo $this->smart->result() . '<br>'; // output: 88
    echo $this->smart->predicate() . '<br>'; // output: Layak
  }
}
