“…In expressing the degree of certainty, CF assumes the degree of certainty of an expert on a data [2]. The following is a description of some combinations of Certainty Factor for various conditions [2,[13][14][15]: Where ( ) is CF of the CF value given by the expert (between 0 and 1) and ( ) is inputting the CF value from the user input. In step 1, the calculation is done by multiplying the second input, that is, CF users and CF experts with the results of the values obtained will be accommodated to CF1, and to get the value of 2 it is necessary to repeat step 1.…”

Kepribadian adalah sifat dan kebiasaan seseorang yang membedakannya dari orang lain. Identifikasi gangguan kepribadian penting untuk semua orang. Kondisi kepribadian yang mencerminkan kondisi mental yang sehat. Namun, tidak bagi manusia untuk tidak bisa menerima tekanan pada diri sendiri. Dalam beberapa kasus, banyak orang ingin melakukan pengujian dengan sumber daya yang cukup dan verifikasi yang sesuai. Untuk mengatasinya, diperlukan tes validasi untuk metode deteksi cacat. Metode yang mendukung validasi adalah Metode Dempster-Shafer dengan Metode Faktor Kepastian.Analisis validasi dilakukan pada metode Dempster-Shafer dengan metode Certainty Factor karena menimbang nilai kerusakan kedua metode ini diperlukan dari data hipotesis atau perubahan dalam bentuk data simptom. Analisis validasi dilakukan pada nilai bobot yang dihasilkan untuk setiap metode yang diterapkan. Dari hasil analisis validasi, nilai bobot yang diperoleh dengan metode Demp-ster-Shafer dapat menghasilkan nilai bobot yang lebih akurat.

“…The evidence is derived from the user's answer to questions built on a stored rule or hypothesis. Each user's answer will have a certain value or commonly called the user value [7] Therefore, it can be concluded that in an expert system there are two (2) values that are considered to interfere with the problem-solving process to produce a conclusion or decision, namely hypothesis (expert value) and evidence (user value) [8] The conclusions of the expert system are formulated as follows: Hypothesis (expert value) and evidence (value of user) as described previously is a value of certainty so it requires a problem-solving technique of certainty or probability theory [6]…”

The Certainty Factor method is used as a method of resolving the problem of certainty by calculating every possible value. The Certainty Factor method calculates the probable value of all the factors involved in a problem. The result of a certainty factor calculation is the result of a combination of the calculation of each factor. The combination stage of the certainty method is standard so that the calculation results will be greatly affected by the calculation of the first-factor value calculated. The certainty factor method is also known as the expert system solution method that has been used in many studies in diagnosing a problem. The influence of probability value of the first factor greatly influence the diagnosis result, therefore needed a research which discusses modifies at combination stage of method certainty factor.

“…Sistem pakar tidak hanya digunakan untuk mendiagnosa penyakit pada manusia tapi juga dapat digunakan sebagai diagnosa penyakit pada tanaman yaitu diagnosa hama anggrek coelogyne pandurata dengan metode penerapannya adalah metode forward chaining dan CF [6]. Metode CF juga digunakan dalam sistem pakar diagnosa hama dan penyakit pada tanaman bawang merah [7], hasil yang diperoleh adalah masih kurangnya pakar yang dapat memberikan informasi mengenai solusi terbaik dalam permasalahan yang ada.…”

There are two factors that cause a disease, called Congenital and Acquired. Congenital refers to a disease a person is born with, while Acquired refers to a disease acquired after a person was born such as infection, trauma, and neoplasm. The infected person will sometimes require information on the disease before going to the doctor or a hospital. Such information may be found from a system which receives input on the symptoms and gives a clear information on the corresponding disease. This may be achieved via a system of experts, in which the expert refers to an ENT (Ear, Nose, and Throat) specialist. Such information is hoped to provide a solution on the disease. The system of ENT specialists designed and research in this paper used the certainty factor method. The method will overcome the uncertainty in decision making depending on the symptoms described by the user. This paper is successfully applied certainty factor method used as an instrument of decision making in the system of ENT specialists. The system is web-based, enabling the user to access and choose the symptoms of the disease as well as acquiring information on ENT diseases easly.Abstrak-Faktor dan penyebab suatu penyakit ada dua yaitu Kongenital dan Acquired. Kongenital merupakan penyakit bawaan sejak lahir dan Acquired merupakan penyakit yang didapat setelah lahir (penyakit yang bukan bawaan sejak lahir) seperti infeksi, trauma, Neoplasma (keganasan/tumor). Penderita suatu penyakit terkadang membutuhkan informasi mengenai penyakit yang dialami sebelum memutuskan untuk berobat ke dokter atau rumah sakit. Informasi tersebut bisa didapatkan melalui sistem yang dapat menerima inputan berupa gejala penyakit dan memberikan informasi yang jelas mengenai penyakit tersebut. Hal ini dapat dilakukan menggunakan sistem pakar, dalam kasus ini pakar merupakan dokter spesialis THT (Telinga, Hidung, dan Tenggorokan). Informasi tersebut diharapkan memiliki solusi dari penyakit yang diderita. Sistem pakar penyakit THT yang dirancang dan diteliti pada penelitian ini menggunakan metode certainty factor. Metode ini dapat mengatasi ketidakpastian dalam pengambilan keputusan berdasarkan gejala-gejala yang dirasakan atau diinputkan oleh user. Penelitian ini telah berhasil dan tepat menerapkan metode certainty factor sebagai alat pengambilan keputusan pada sistem pakar penyakit THT. Sistem ini berbasis web, sehingga user dapat dengan mudah mengakses dan memilih gejala yang dirasakan serta mencari informasi mengenai penyakit THT.Kata kunci-Certainty Factor, sistem pakar, THT (Telinga, Hidung, dan Tenggorokan), web
