Gigi adalah organ yang patut diutamakan pemeliharaannya. Oleh sebab itu menjaga kebersihan gigi dan mulut merupakan hal yang sangat penting. Sebagian besar masyarakat pada umumnya seringkali menganggap remeh suatu penyakit, sehingga pada saat pasien ditangani oleh tenaga paramedis pasien telah mengalami kondisi yang lebih parah dikarenakan minimnya informasi atau fasilitas untuk mendiagnosa penyakit gigi dan mulut, serta biaya untuk periksa ke dokter yang tidaklah murah. Kurangnya sarana komunikasi dan alat informasi menjadi salah satu hambatan dalam kasus ini. Sehingga perlu adanya media untuk membantu penderita dan para medis dalam menangani kasus ini. Oleh karena itu diperlukan Sistem Pakar yang bertujuan untuk mendiagnosa penyakit pada gigi manusia agar membantu penderita untuk mendapatkan jawaban dari penyakit yang dihadapinya. Adapun metode sistem pakar yang akan digunakan dalam penelitian ini adalah Teorema Bayes. Teorema Bayes merupakan teorema yang digunakan untuk menghitung peluang dalam suatu hipotesis. Teorema ini juga merupakan dasar dari statistika Bayes yang memiliki penerapan dalam ilmu ekonomi mikro, sains, teori permain, hukum dan kedokteran.

Abstrak - The acceleration of data communication in the world of information technology is developing very fast, more than millions of digital messages are exchanging every day in cyberspace. These digital messages are freely communicating on internet networks or public networks that result in anyone being able to access these digital messages. Because the openness of the internet network that involves many people can take digital messages, the protection for the messages should be good. Digital message protection is used so that digital messages are directed to their intended destination, for this reason, a method is needed to maintain the confidentiality of the digital message. Cryptogafi is the study of encoding. By using cryptography digital messages can be changed into passwords so that the confidentiality of digital messages is maintained. Many algorithms can be used to change the original message (plaintext) into a password (ciphertext), one of which is the XOR cipher that utilizes the binary of each character. XOR cipher has a security hole that can be used by cryptanalysts such as using known-plaintext attack, ciphertext-only attack, and flip bit attack. Therefore, to increase the confidentiality of the message, the binary plaintext generated by the XOR cipher will be encrypted again using the Merkle-Hellman Knapsack. The results of this hybrid cryptosystem add a high level of digital message security because the binary ciphertext will re-form the ciphertext with Merkle-Hellman Knapsack, thus forming twice the protection.Keywords - Digital Message, Hybrid Cryptosystem, XOR Cipher and Merkle–Hellman Knapsack Abstract – Percepatan komunikasi data dalam dunia teknologi informasi berkembang sangat cepat, lebih dari jutaan pesan-pesan digital setiap harinya saling bertukar didunia maya. Pertukan pesan digital ini secara bebas berkomunikasi di jejaring internet atau jaringan umum yang mengakibatkan setiap orang dapat mengakses pesan digital tersebut. Sebab keterbukaan jaringan internet yang melibatkan banyak orang bisa mengambil pesan digital tersebut maka sudah seharusnya perlindungan untuk pesan tersebut harus baik. Perlindungan pesan digital tersebut digunakan agar pesan digital tertuju ke tujuan yang semestinya, untuk itu perlu adanya metode untuk menjaga kerahasiaan pesan digital tersebut. Kriptogafi merupakan ilmu yang mempelajari tentang penyandian. Dengan menggunakan kriptografi pesan digital dapat diubah menjadi sandi sehingga kerahasiaan pesan digital terjaga. Ada banyak algoritma yang dapat digunakan untuk merubah pesan asli (plaintext) menjadi sandi (ciphertext) salah satunya XOR cipher yang memanfaatkan binary dari setiap karakter. XOR cipher mempunyai celah keamanan yang dapat dimanfaatkan kriptanalis seperti menggunakan known-plaintext attack, ciphertext-only attack dan flip bit attack. Oleh sebab itu untuk meningkatkan kerahasiaan pesan maka binary plaintext yang dihasilkan oleh XOR cipher akan enkripsi lagi menggunakan Merkle–Hellman Knapsack. Hasil dari hybrid cryptosystem ini menambahkan tinggat keamanan pesan digital karena pada binary ciphertex akan membentuk ciphertext kembali dengan Merkle–Hellman Knapsack, sehingga membentuk dua kali perlindungan.Kata kunci – Pesan digital, Hybrid Cryptosystem, XOR Cipher dan Merkle–Hellman Knapsack

Many of the problems that occur in large-scale computer network one of the problems is a complex network design and difficult to change because the system is running, one of these problems is within the university network, as is known the number of most Internet users come from the university, therefore design or reliable network design is required for good access at the university. Hierarchical network model is one of the efficient network design to be applied in large-scale networks. This model uses 3 layers (layer) namely core layer, distribution layer and access layer. Each layer will be maximized for use in the university network distribution layer will use inter vlan routing which will then be distributed to the faculties acting as the access layer. Network design with hierarchical model will also make it easier to monitor or monitor network traffic so it will be easy for the network administration in managing the work.

The BSM Program is a National Program aimed at eliminating the barriers of poor students participating to school by helping poor students obtain proper access to education services, preventing dropping out, attracting poor students to return to school, helping students meet needs in learning activities, supporting compulsory education programs 9 Years (even up to middle level), as well as help smooth school programs. To obtain the Poor Student Assistance (BSM) fund, the government sets out some criteria for who are the students who can be eligible and entitled to receive Poor Student Assistance (BSM). The criteria will be later that will assist the school or educational institution in determining which students can be eligible to receive Poor Student Assistance Fund. Therefore, an educational institution must have a Decision Support Support System of Poor Student Fund (BSM) using Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method, with a decision support system of Poor Student Assistance (BSM) is expected to be successful, on target, and accepted by the rightful person. Thus the decision maker can compare the performance between the old system with the BSM funding decision support system with the method of Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) without having to ask back the data of students who will be given Poor Student Assistance funds.

In managing a large network, it takes the ability to manage the network so that traffic is good. To connect to such a large network requires many routers, each router will connect to one another. But the best choice of any router is required for network traffic efficiency. There are two routing protocols that can be used, namely static routing and dynamic routing. EIGRP is dynamic routing which, principally between routers, can communicate directly and dynamically, so that when there is a new router in a network, routers can communicate directly because they can exchange information. EIGRP uses the Diffussing Update Algorithm (DUAL) in determining the best path. In this study, EIGRP metrics will be analyzed to try the best path on the network by sending Internet Control Message Protocol (ICMP) packets. There are two networks that will be tested with differences in the Fast Ethernet bandwidth interface of each router. This experiment resulted in different values between Fast Ethernet default bandwidth and non-default bandwidth, so that the value of the variable affects the selection of the best path of network traffic
