Abstract

Quick progress also occurs in the field of cellular communication networks with the concept of open systems, making it easier for someone to enter into the network. This can cause the process of sending data to be unsafe because it can be used by other parties who are not responsible for taking data and information in the middle of the road. To achieve the goal of maintaining confidentiality, various kinds of security techniques have been developed. To protect and maintain the confidentiality of data to avoid people who are not entitled to obtain this information, namely using cryptographic methods. In terms of data security techniques, many cryptographic methods can be used. Cryptographic methods have their own techniques and methods. One of the cryptographic methods that can be used is the Reverse Cipher method. But if you only use the Reverse Cipher method, text data security is very weak. So to achieve a higher level of security this method is combined with the RSA method which uses a public key and has high security because the difficulty of factoring large numbers becomes prime factors in the RSA algorithm.

Abstract

Kurangnya pengetahuan publik tentang perilaku abnormal berakibat perilaku-perilaku abnormal yang ada dan tampak sering dipahami secara keliru, bahkan tidak jarang penyandang perilaku abnormal diperlakukan secara tidak manusiawi. Bukan hanya pada orang dewasa, perilaku abnormal juga dapat dialami oleh anak-anak. Salah satu bentuk perilaku abnormal tersebut adalah Attention Deficit Hyperactivity Disorder atau gangguan pemusatan perhatian pada anak. Tujuan dari penelitian ini adalah membuat suatu aplikasi sistem pakar yang berjalan pada sistem operasi windows yang dapat mendiagnosa gangguan Attention Deficit Hyperactivity Disorder dengan memberi hasil diagnosa berdasarkan tingkat keyakinan terhadap gejala-gejala yang diderita pasien dengan metode Certainty Factor. Penerapan metode Certainty Factor dapat memperkuat diagnosis yang dihasilkan karena sistem mempunyai nilai sehingga tingkat kepastian atau tingkat keyakinan lebih akurat. Dari sistem yang dirancang dan hasil pengujian secara manual diperoleh nilai keakuratan sebesar 0,9676 atau bila dipersentasikan nilainya menjadi 96,76% untuk gejala Combine (Inatentif, Hiperactif / Implusif dan Implusif ).

Abstract

The selection of laying ducks on a farm is an important step for the continuity of activities in it. Increasing the selection of laying ducks requires quality standards to measure its success. This increase uses a simple additive weighting (saw) method in a decision support system. The increase in the selection of laying ducks is based on several criteria that have been applied, including the age of the ducks, the weight of the ducks, the shape of the duck feathers, and the shape of the duck wings. The results of this study indicate that the proposed model can be used properly in carrying out the selection of parent ducks for laying eggs. The SAW method is able to produce decisions in the form of the best alternative that can be used to assist decision makers. so that it can assist in the selection of broodstock ducks in an ordinary or intensive farm.
