Abstract

Decision support system is a system adopted from human knowledge, which can help people in the decision making process. In research conducted at PT Coal Bukit Asam (Persero) authors see most of the systems currently used in the search process of promotion of employees still in manual form, causing the length of the assessment process associated with a promotion for every employee of the company in accordance with any the criteria that have been specified company. Various weighting of criteria and sub criteria established companies are always considered manager to each process of inputting assessment. Therefore, the authors make a decision support system application manager that can facilitate the process of inputting weight rating decision promotion of employees in accordance with the criteria and sub-criteria that have been specified company. Application decision support system of promotion is designed using Analytical Hierarchy Process that the process to obtain the priority weighting is done by comparing each criteria and sub-criteria. Decision to be achieved can help managers to determine who the employees are entitled to a promotion in accordance with keptusan obtained from the application of this decision-making system.

Abstract

The use of electronic media is expected to help the archive managers to manage their archives effectively and efficiently. By using electronic media in the management of Archives will be obtained the benefits of speed, convenience and savings. The purpose of speed here is through the use of electronic media, the process of searching, discovering, distributing and processing data is carried out in a short time. The purpose of the ease of use of electronic media is the ease in terms of search, distribution and processing of data, which is efficient in the use of electronic media that can reduce energy, mind and save costs in managing archives. With these reasons, at present many organizations / agencies that use electronic media in the management of archives, ranging from simple to sophisticated. At the Forestry Service of North Sumatera Provinceexperience difficulties in the management of receiving and storing various letters, reports, forms and so on. The administration section is one of the parts of the Forestry Service of North Sumatra province of Batujajar. This work Unit manages the archives as the end result of administrative activities. One type of archive that is managed is the Mail Files. This file has not been done electronically.

Abstract

WFZ Book Store is a Book Store that provides various types of books. The sales process is done offline where the costumer has to visit the store to make a purchase. The process of recording data using the ledger makes it difficult for WFZ Book Store to make sales reports because it has to collect transaction data in the ledger, it causes difficulties to know the available Book stock because it has to check every sales transaction in the ledger. WFZ Book Store requires an information system that can manage book sales data onlineagarcostumers can easily view book data, stockand book online reservations. With the wfz Book Store information system can facilitate the customer in managing book data and store customer data that has made transactions also WFZ Book Store does not find it difficult to provide book purchase transaction data for the customer, so that the data can be used for book recommendations by finding the set of data that most often appear in a data set. Datamining techniques have been widely used to overcome existing problems, one of which is the application of a-priori algorithms to find association rules formed from book purchase transaction datasets. So it will be known the association between the title of the book purchased. The association rules between book titles formed from the mining process can later be used by the WFZ Book Store to increase the number of books purchased, besides that it can be used for the procurement of books from the association rules of frequently purchased books, it can also be developed into a knowledge base for the book purchase recommendation system. The Output is in the form of a priori algorithm analysis software.

Abstract

Diseases of the teeth and mouth are one of the many health problems that often interfere with the activities of sufferers. Diseases attack indiscriminately Reed both children and adults. Dental and oral health is an important thing that needs to be considered. Problems that occur in the teeth and mouth must be handled properly so as not to cause other problems that occur due to improper handling. Doctors are required to provide decisions quickly, and accurately in diagnosing diseases suffered by their patients. But to make such a diagnosis is not easy, considering that each disease has more than one symptom, and several different diseases have almost the same symptoms. Decision - making in diagnosing the disease carefully and appropriately must be done quickly for the treatment process of the disease. Especially for young doctors and all doctors if they find cases that are difficult to diagnose, they will generally be guided by books. This will certainly take time and effort. Treatment for this problem is to build an expert system application that functions to diagnose diseases of the teeth and mouth. This expert system application is expected to help doctors in deciding to diagnose diseases quickly or become a matter of consideration or reference.

Abstract

Understanding the electricity tariff class is needed to predict how much usage costs or electricity bills that must be incurred by customers. Each power capacity has a different basic electricity tariff based on the class, household, business and industry. Fuzzy logic can solve problems with imprecise and heuristic data by producing accurate conclusions. The conclusion obtained from the Fuzzy Logic results is expected to be a consideration for customers in predicting electricity usage costs based on electricity tariff groups and customer electrical power capacity. The proposed research uses the Mamdani Fuzzy Logic Method, the use of this method aims to facilitate customers in predicting the cost of electricity usage based on the electricity tariff class and the customer's electric power capacity. The output of this research is the result of predicting the cost of electricity usage based on the power group in residential homes. The higher the tariff group, the number of kWh, electronic goods, and usage time, the higher the predicted energy consumption used. The results obtained from adjusting the fuzzy input antecedents and fuzzy values, namely [900;850;30;20], then for Type_Tariff Power 900, Total_KWh 850, Electronics 30, and Time_Use 20 is 986. Then the cost that must be incurred in the example case above is 1,333,072 rupiah.
