ABSTRAK

Depresi dan Demensia adalah salah satu gangguan yang banyak ditemui pada lanjut

usia.Berdasarkan data pada WHO(World Health Organization) di Canada, orang yang hidup

dalam lingkungan institusi sebesar 30–40 % mengalami Depresi dan Demensia. Data penderita

Depresi dan Demensia di Canada yang cukup besar disebabkan karena penanganan yang lambat

terhadap Depresi dan Demensia. Penanganan yang lambat tersebut disebabkan karena gejala-

gejala dari Depresi dan Demensia yang mirip dengan perilaku dalam kehidupan sehari hari.

Sehingga,pada saat kondisi parah baru diketahui menderita Depresi dan Demensia

Berdasarkan kasus diatas pada penelitian Tugas Akhir ini ingin membuat sebuah Sistem

Pakar.Sehingga,dapat membantu untuk memberikan diagnosa awal mengenai penyakit Depresi

dan Demensia sekaligus mampu memberikan penanganan awal Depresi dan

Demensia.Pembentukan rule pada sistem pakar menggunakan metode Forward Chaining yang

memproses hasil diagnose dengan berdasarkan gejala gejala yang ada hingga menuju kesimpulan

. Untuk menghitung nilai probabilitas dari masing masing kesimpulan digunakanlah metode

Dempster Shafer.

Berdasarkan hasil pengujian dengan menggunakan data rekam medis penderita Depresi

dan Demensia pada RSUD Wangaya sebanyak 50 data rekam medis didapatkan 41 data (82%)

hasil prediksi sistem pakar memberikan hasil yang sesuai dengan yang diharapkan.

ABSTRACT

Depression and dementia are a disorder that is commonly found in an elderly age. Based

on the data of the WHO (World Health Organization) in Canada, 30-40% of the people living in

the institutional environment undergo Depression and Dementia. Depression and dementia

patients in Canada are quite large due to the slow handling. Handling is slow because the

symptom of depression and dementia is similar to the behavior in daily life. Thus, only when it is

in a severe condition, is it known that one suffers from Depression and Dementia.

Based on the case above, this final assignment wishes to create an expert system that can

help to provide an early diagnosis of Depression and Dementia diseases at the same time it is

able to provide initial treatment of Depression and Dementia. The formation of rule on expert

system used Forward Chaining method that processed the diagnostic results based on the existing

symptoms leading towards the conclusion. To calculate the probability values of each

conclusion, Dempster Shafer method was used.

Based on test results using medical records of Depression and Dementia patients in

Wangaya hospital, of the 50 medical records of data obtained, 41 (82%) of the prediction results

of the expert system yielded the expected results.

Keywords: Depression, Dementia, Forward Chaining, Dempster Shafer, Expert System

KATA PENGANTAR

Puji syukur penulis panjatkan kehadapan Tuhan Yang Maha Esa , karena berkat rahmat
