<![CDATA[At present the growing number of smartphones is growing which makes managers want to get a better promotional strategy. The way to find the right sales strategy will be to reduce the cost of promotion and achieve the right sales goals. One way that can be done to determine the promotion strategy is to use data mining techniques. The technique used in this case is the FP-Growth Algorithm. FP-Growth is one alternative algorithm that can be used to determine the set of data that most often appears (frequent item sets) in a data set. FP-Growth algorithm is the development of Apriori algorithm. Whereas in the FP-Growth algorithm no candidate is generated because FP-Growth uses the concept of tree development in searching for frequent itemset. The study was conducted by observing several research variables that are often considered by companies especially in marketing in determining the promotional objectives, namely user objectives, user experience, service, analyst. The results of this study are in the form of a software by implementing the FP-Growth algorithm that uses the concept of FP-Tree development in searching for Frequent Itemset]]>

<![CDATA[The prophet who is obliged to believe there are only twenty-five (25) prophets, in the twenty-five prophets, every prophet has a genealogy, with so many genealogies of the Prophet, every Muslim, especially young men and women, need to know the genealogy of the Prophet , it would be a problem if when someone asked about the Prophet's lineage did not know at all, because many Muslims curiosity about the Prophet's genealogy was few and only certain people knew. In the case of searching the genealogy of the Prophet, the Crochemore-Perrin algorithm is very suitable to use because it is able to search from two directions, from front and back, the Crochemore-Perrin algorithm factifies the pattern into two parts of the left pattern, and the right pattern so that the pattern is the same as the left pattern. right. Crochemore-Perrin algorithm can solve the problem of searching the Prophet's lineage because it is easier and faster. The solution to the problem of these problems is to design and build a search application for the Prophet's genealogy that is easily accessible wherever it is and easy to operate. With the application of the genealogy of prophets is expected to facilitate the Islamic community to find and know about the genealogy of the Prophet]]>

<![CDATA[Optimization is a step called to determine the profit and loss of a company in its activities. This optimization is related to yield and production problems that often occur in a company. PT. Alfa Scorpii Pematangsiantar has objects that are marketed through marketing and sales counters. The object being marketed consists of three parts, namely a sports motorcycle, an automatic motorcycle, and a motorcycle. The problem of determining the cost of promotion in the Pematangsiantar Yamaha show room is still determined based on estimates. Marketing manager incurs sales costs based on several factors that influence such as employee costs in marketing motorbikes, promotion costs in the form of brochures of motorcycle types, prices offered. The amount of sales costs must also be based on the number of units of motorcycles sold, if it is reduced, the company will suffer losses, and sales costs must always be incurred during the motorcycle sales process will be minimized, if sales go up, the company will experience profits, then sales costs can maximized. To optimize sales costs to make a profit, the determination of sales costs can be completed using a linear program model. Several ways to solve problems with the linear program model, including being solved by the Simplex Method]]>

<![CDATA[Issues Security and confidentiality of data is one important aspect in terms of information exchange. One solution to maintain security and confidentiality in the process of sending files with encryption techniques as encryption keys on voice files. This study describes developing cryptography (encryption and decryption) that applies the Spritz algorithm. But not all developments in communication technology have a positive and beneficial impact. One of the negative effects of sound files is data tapping, which is one of the most feared problems by network users and voice files. This research resulted in an application program aimed at preventing the security of sound files on storage media. in making this application, the method used is the Spritz algorithm, because it is very suitable for the security of voice files that result in the completion of the encryption and decryption process. This application was created with visual basic 2008 software and the creation of a file security application using encryption and decryption processes using the Spritz algorithm is expected to overcome these problems. The format used in making this application encrypts and decrypts the sound files that have an extension. WAP, and MP3]]>

<![CDATA[Recognition of letters is one of the capabilities of artificial neural networks (ANN) both recognition of facial patterns, fingerprints, handwriting and character patterns, and printouts. The problem experienced in the introduction of the Karo tribe is the difference between the letters of the alphabet and the letters of the script very different, both in form and how to read it, and must be able to recognize each one of the letters. In learning the karo tribe, a person can experience difficulty in learning it. Therefore, the introduction of karo characters is needed to avoid mistakes in the introduction of Karo tribe letters and makes it easier for the public to know or recognize the characters of the karo tribe. The perceptron method is able to recognize the karo characters which will result in the recognition that the image object can be recognized by the network, making it easier for humans to manage data in a program through a pattern of input that is recognized in advance so that the network can be made from a black and white image]]>

<![CDATA[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]]>

<![CDATA[Islamic Shari'a (The word syara 'etymologically means "paths that can be traveled by water"), meaning that the path traveled by humans towards God. Sharia Islamiyyah is an Islamic law, or regulation, which regulates all aspects of the life of Muslims. In addition to containing laws, rules and guidelines for life, Islamic law also contains the key to solving all problems of human life both in the world and the hereafter. Many Islamic Sharia must be known to every Muslim because by studying Islamic Sharia a Muslim will know which obligations and rights as a servant of Allah SWT. In general, Muslims need fiqh books or fiqh books to help find law in Islam. But often Muslims do not bring books or books of jurisprudence, because books have a large size because there are so many discussions in them. The use of books or books is also considered to be long enough in the search for Islamic Sharia so that slowing Muslims in learning. The zhu-takaoka algorithm is a string matching algorithm that can search words with a lot of shifts, namely with an array of 2 (two) dimensions. The core process of searching for the zhu-takaoka algorithm is to search for words using the Right-to-left scan rule technique. Each shift in the word search process is determined by the shift values in the Good Suffix Shift Rule and Bad-Charcter Shift Rule tables. With this algorithm, it is expected to be able to facilitate the user in the process of searching for Islamic law]]>
