Background

• 90% Parents know least information
• 90% Parents don’t understand what the symptoms is
• Mother take a decision to do work activities outside the

• Help parents in providing information about autism

spectrum

• Help parents in early diagnosis of children’s behavior

based on the symptoms experienced

• Help parents to provide curriculum guidance and

therapy in children with autism spectrum disorder, with relatively low cost and short time into the expert system application

Testing: Certainty Factor Calculation

CF(A) = CF(G(25)) + CF(G(26))) * [1-CF(G(25))] = 0,5 + 0,6* [1 – 0,5] = 0,8 (4.1) CF(B) = CF(G(2)) + CF(A) * [1-CF(G(2))])] = 0,6+ 0,8 * [1 – 0,6] = 0,92 (4.2) CF(C) = CF(G(3)) + CF(B) * [1-CF(G(3))])] = 0,8+ 0,92 * [1 – 0,8] = 0,984 (4.3) CF(D) = CF(G(5)) + CF(C) * [1-CF(G(5))])] = 0,8+ 0,984 * [1 – 0,8] = 0,9968 (4.4) (4.4) * 100 = 99,68% (4.5)

No. Category Total Average Score Satisfaction Level 1. Interface 3.40 Very Good 2. Functionality 3.07 Very Good 3. User Friendly 3.15 Very Good

Testing: User Acceptance Test

Level of satisfaction: 3.1 – 4.0 = Very Good 2.1 – 3.0 = Good 1.1 – 2.0 = Fair 0.1 – 1.0 = Poor

Conclusion

Expert System application is :

• success to be provided and presented the full article and the

curriculum steps for parents, and parents can do consultation

• n the application with fees are relatively inexpensive and do

not require long time

• success to provide value to the accuracy of the diagnosis in

accordance to calculation certainty factor method.

• success to be built with the PHP programming language and

to be hosted in the www.esdas.windyaz.com website.

Suggestion

Expert System application is expected to :

• Diagnose ASD in children aged over 5 years old
• Provide the function to store diagnosis in user data
• Be developed in responsive display
