IMPLEMENTASI ALGORITMA F-AHP PADA SISTEM PAKAR

DETEKSI PENYAKIT TUBERKULOSIS PARU BERBASIS WEB

ABSTRAK

Perkembangan teknologi informasi memberikan informasi-informasi yang

relevan, akurat, tepat waktu dan memberikan informasi yang dapat digunakan

untuk membantu dalam mengambil sebuah keputusan. Salah satu contohnya

adalah pengambilan keputusan dalam mendeteksi penyakit Tuberkulosis Paru

pada pengguna. Penyakit Tuberkulosis Paru merupakan penyakit yang penting

dan paling sering ditemui di dunia. Penggunaan teknologi informasi yang

berkembang dengan pembuatan sistem dapat digunakan sebagai sarana pengguna

untuk mendeteksi dini penyakit Tuberkulosis Paru. Pembuatan sistem untuk

mendeteksi penyakit Tuberkulosis Paru menggunakan algoritma Fuzzy Analytical

Hierarchy Process (F-AHP). Algoritma F-AHP dibagi menjadi dua tahap yaitu

AHP dan F-AHP. Algoritma AHP digunakan sebagai menentukan nilai hasil

konsistensi data yang digunakan. Algoritma F-AHP digunakan sebagai penentu

akhir bobot masing-masing data kriteria yang digunakan. Pada penelitian ini,

pengujian sistem dilakukan dengan menguji metode dan menguji ketergunaan

sistem. Pengujian metode dengan membandingkan nilai hasil bobot akhir antara

perhitungan sistem dengan perhitungan manual dan menghasilkan nilai yang

sama. Pengujian ketergunaan sistem menggunakan system usability scale (SUS)

dengan pakar menghasilkan skor 82.5 dan termasuk ke dalam kategori

“Acceptable”, sedangkan ketergunaan sistem berdasarkan pengguna menghasilkan

skor 86.16 dan termasuk ke dalam kategori “Acceptable”.

IMPLEMENTATION FUZZY AHP ALGORITHM ON EXPERT SYSTEM

TO DETECT PULMONARY TUBERCULOSIS DISEASE

WEB BASED

ABSTRACT

The development of information technology provides information that is relevant,

accurate, on time and provides information that can be used to assist in making a

decision. For example is making decision in detecting pulmonary Tuberculosis

disease at users. Pulmonary Tuberculosis disease is an important and most

common disease in the world. Using the information technology that develops by

creating a system that can be used as a means of users to detect early pulmonary

Tuberculosis disease. In making a system to detect pulmonary Tuberculosis

disease using the Fuzzy Analytical Hierarchy Process (F-AHP) algorithm. The F-

AHP algorithm is divided into two stages, AHP and F-AHP. The AHP algorithm

is used to determine the value of data consistency from data that has been used.

The F-AHP algorithm is used as final determinant of the weight value of each

criteria data used. In this study, testing system is done by testing the method and

testing the usefulness of the system. Testing the method by comparing the value

of the final weight between the system calculations and manual calculations and

produces the same value. Testing the usefulness of the system using System

Usability Scale (SUS) based on expert produces score 82.5 and included in the

category “Acceptable“, while SUS based on users produce score 86.16 and

included in the category “Acceptable“.
