Abstract

This Decision Support System is to make it easier for each student to choose an organization that is in accordance with the wishes of each student, so that students will not regret later when they have joined as members or administrators of the organization itself. The organization is a group of people who work together for a common goal and can also be a forum for people to gather and work together rationally and systematically, planned, guided and controlled, in developing interests and talents as the goals of the organization itself. VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) is a multi-criteria optimization method used in complex systems. This method focuses on ranking and choosing from a set of alternatives, and specifies a compromise solution to the problem of conflicting criteria, which can help decision makers to reach the final decision. Here, a compromise solution is a viable solution that is closest to the ideal, and compromise means an agreement is established with mutual concessions.

Abstract

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

Abstract

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

Abstract

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
