Abstract

Diseases of the digestive system are a type of disease that often attacks rabbits. This disease is also one of the causes of death in rabbits. This is based on interviews with veterinarians who say that, if diseases of the digestive system are not given the treatment quickly and precisely it will cause death in rabbits. Most veterinarians only open practices in big cities, so it is not uncommon for rabbit breeders who are late in giving treatment to diseases of the digestive system suffered by their pet rabbits. Based on the above problems, it is necessary to create an expert system that can help rabbit keepers and veterinarians in diagnosing diseases in the digestive system of rabbits, because so far there has not been any application to deal with this. The Fuzzy Expert System method will calculate every symptom experienced by rabbits by using the inference method from mamdani. In the Mamdani method, both input and output variables are divided into one or more fuzzy sets. The end result will be done by the process of processing a fuzzy set obtained from the composition of fuzzy rules to produce output in the form of a number in the fuzzy set domain, while this process is called affirmation (defuzzification). From the results of testing the system using the visual basic 2008 program is good to use, but still needs a lot of development in applying it to the expert system

Abstract

The strength of the algorithm used in data security does not only depend on the complexity of the algorithm used, but lies in the randomness and complexity of the key solving used. The repetition of the same character in the formation of a key used by a data security algorithm is very vulnerable to attack, because it can make it easier for attackers to break the algorithm itself. One of the commonly used data security algorithms is the comfort cipher algorithm. The number of key characters needed in this algorithm is directly proportional to or equal to the number of characters of text or data that is secured. Using a number of key characters like this allows the repetition of the same characters, making it easier for attackers to find out the pattern of the keywords used. Based on this, random key generation is necessary to optimize the robustness of the algorithm used. Multiply with carry generator is a random number generation technique that has advantages in speed and length of randomization cycle so that it has more seed variations to the generated random numbers. This study describes how to apply this random number generation method to generate keywords used in the beaufort cipher algorithm, so that the keys used can be more optimal and more complicated for attackers to crack.
