<![CDATA[Bazaar is a trading activity that is based on a committee that meets the requirements with the division of tasks in accordance with available resources. Bazaar is usually carried out when welcoming the End of the Odd Semester Examination and as an event or routine every year, with bazaar decorations that attract the interest of visitors. In carrying out the Bazar, the organizer often experiences problems in determining the Best Bazaar Stand. Among them, Invalid data, constrained by limited time and Lack of experience of the Bazar implementers so that in practice participants have insufficient and uncoordinated concepts, Failure in carrying out the bazaar can also be influenced by poor or insufficient loyalty control which results in a shortage of and out of stock, which results in disappointed customers and leaving the bazaar stand. A bazaar data collection study was conducted in semester 8 of STMIK Budi Darma Medan, based on predetermined criteria. Followed by the calculation of the value of each Alternative by using the MOORA method to produce the best alternative. Of the 10 alternatives taken, Alternative A2 became the highest ranking result, with a value of 0.29051 as the best Bazaar Stand at STMIK Budi Darma Medan.]]>

<![CDATA[Education is one thing that is very important for one's life, education also plays a big role for the progress and development of a nation. A developed and large nation that is certainly supported by adequate quality education for its citizens. One of the countries that has the best education level in the world is Finland. Finland is currently in fifth place after Hong Kong. Continuing college education in Finland is the desire of many Indonesian students, especially through scholarships, because continuing education in Finland can gain a lot of knowledge that may be rarely found in Indonesia. String Matching is an algorithm used to speed up the search process for the desired word. String matching is divided into two, namely exact matching and heuristic or statistical matching. The string matching algorithm has often been used before as an example in the string matching process based on the data text equation, namely Brute Force. In this case, the brute force algorithm is chosen because this algorithm can be used to search strings or texts. Brute force algorithm is an algorithm to match patterns with all text between 0 and n-m to find the existence of patterns in text. With the development of technology today string matching can also be used in education. Education is one thing that is very important for one's life. To overcome the above problems the authors build an android-based application, namely the Indonesian-Finnish translator application. In the search tools the author implements the string matching algorithm namely zhu takaoka algorithm. The zhu takaoka algorithm is one of the best algorithms that can do the string matching process quickly because it shifts with bad characters for two text characters in a row from right to left.]]>

<![CDATA[Text messages are very vulnerable to the encoding or theft of information by irresponsible parties. In order to maintain the security of text messages, it can be done by using cryptographic techniques. Cryptographic techniques can encode text messages by encrypting them in the form of passwords that are not understood. The FEAL algorithm is a symmetrical block chipper type encryption algorithm, which has a block length of 64 bits, a length of 64 bits, and has an iteration of 8 rounds. The RSA algorithm is one algorithm that can be relied upon in realizing cryptographic techniques. This asymmetry algorithm will produce a higher level of security against text messages because the process is quite complicated with generation and uses different keys so that it will be difficult for cryptanalysts to access the text messages. This research will use FEAL and RSA Algorithm for the encryption and decryption process, so that in the process it is necessary to go through several long steps in order to produce the final cipher. This study describes the process of securing text messages by encoding them based on the FEAL and RSA algorithms, in the form of a password that is difficult for others to understand and understand. This is done as an effort to minimize the actions of irresponsible parties.]]>

<![CDATA[Nucleus hernia (HNP) is a disease that often causes pain in the vertebrae. HNP occurs due to the presence of nucleus pulpus (a filling material in the form of a springy substance such as gell) that comes out of the discus vertebral (spinal joints). Early symptoms of this disease are often not realized by sufferers. As a result of this lack of awareness can actually cause activities to be inhibited. This is because HNP can cause pain in the spine that can affect the pain in the thighs, calves and legs and can even cause spinal deformities. To reduce the risk of this HNP disease, we need an expert system that can help both sufferers and experts in diagnosing the initial symptoms of this disease so that prevention of harmful effects can be done more quickly. In this study, an expert system was made that functions to diagnose the early symptoms of HNP with a case-based reasoning method as an expert system logic that was made. This solution was made because with the help of web technology, patients can easily diagnose the symptoms of HNP anytime and anywhere]]>
