Abstract

Breast cancer is one of the highest causes of death among women, this disease ranks second cause of death after lung cancer. According to the world health organization, 1 million women get a diagnosis of breast cancer every year and half of them die, in general this is due to early treatment and slow treatment resulting in new cancers being detected after entering the final stage. In the field of health and medicine, machine learning-based classification has been carried out to help doctors and health professionals in classifying the types of cancer, to determine which treatment measures should be performed. In this study breast cancer classification will be carried out using the Naive Bayes algorithm to group the types of cancer. The dataset used is from the Wisconsin breast cancer database. The results of this study are the ability of the Naive Bayes algorithm for the classification of breast cancer produces a good value, where the average percentage of correctly classified data reaches 96.9% and the average percentage of data is classified as incorrect only 3.1%. While the level of effectiveness of classification with naive bayes is high, where the average value of precision and recall is around 0.96. The highest precision and recall values are when the test data uses a percentage split of 40% with the respective values reaching 0.974 and 0.973.

Abstract

Banyuwangi Regency has a new innovation called " Lahir Procot Pulang Bawa Akta " which in this innovation is realized in the form of an Online Deed Website. Every information technology has an interface that can be a link between the user and the technology itself. Interface formation is influenced by needs, and information technology has different interface designs according to the needs of its users. The User Interface has the aim of making it easier for users to operate information technology that can make users feel comfortable using the application or technology. Heuristic Evaluation is one of the Usability evaluation methods that can be used to determine the extent to which a system is used by users to achieve certain goals with effectiveness, efficiency and satisfaction. This research is a research that is focused on the use of Heuristic Evaluation based on user interface design aspects of application usability through observation, interviews and questionnaires to users.

Abstract

The forecast model is done using data from several years before, with the involvement of time parameters in the forecast process is usable for the company to made an effective and efficient planning. Forecasting has an important role because the company requires short-term, medium-term and long-term estimates for each management. For short-term estimates, a company requires personnel, production and transportation scheduling, which is part of the process of scheduling and estimating consumer demand. In this study the results of three forecasting methods were compared, there is simple average, naïve and seasonal naive on demand data of PT SUPER SUKSES NIAGA to be further these three method measured its forecast accuracy using the value of MASE (Mean Absolute Square Error). From the results of data pre-processing consumers whose high value of demand are PT. DIESELINDO, PT. DUTA, PT. HEXINDO and PT. PANATAMA. The results of forecasting shown that the method that has the smallest MASE value is the simple moving average method.

Abstract

The application of IT at the University 17 Agustus 1945 Surabaya has not received special attention because the role of information technology is only seen as a business supporter and not a major business. These conditions cause several problems related to the management of information technology at the University 17 Agustus 1945 Surabaya, namely: (1) the application of information technology governance is not optimal, (2) the function of information technology does not yet have a clear strategic and objective direction, (3) The role and employee responsibilities within the Information Systems Department are clearly defined. The purpose of this study is to create an information technology strategy map by applying the cascading balance scorecard process. In achieving the research objectives, ten cascading balance scorecard stages will be carried out, namely analyzing division objectives, identifying the relevance of divisions, identifying customer divisions, identifying division activities, tabulating outputs, identifying customer outcomes, lowering corporate strategy targets to the Division, compiling a strategy map, and determining KPI as well as strategic initiatives. The results of this study are IT strategy maps that show an increase in information technology user satisfaction that will lead to improved performance in conducting academic / non-academic operational activities. In support of increasing IT user satisfaction, IT mastery strategies are needed by all university human resources and enhancing relationships with IT vendors. Whereas in supporting the improvement of the performance of academic / non-academic operational activities, information systems and optimization of IT asset management need to be supported

Abstract

This research discussed the usefulness of the promethee method to solve one of the problems that commonly occur in UD Motto Racing Surabaya. Problems at UD. Motto Racing Surabaya which is still using a manual system in determining the priority of procurement. One alternative solution to this problem is to build a system that can directly produce recommendations to determine the priority of procurement. So that it can minimize errors in the re-stock of goods that result in consumers disappointed. With the existence of this sales information system and priority of procurement of web-based, can help leaders in making decisions for the procurement of goods because comfort and customer satisfaction are the main keys to the company. The results obtained are the priority recommendations for the procurement of goods to be more accurate than without using the system, as evidenced from the results of accuracy testing in the number of April percentages of 66.67%, May percentages of 83.33%, June percentages of 50% and July percentages of 83.33%.
