Abstract

Sales information system is a system designed to simplify the online sales process. Based on research at Roti Nabila Bakery Factory researchers found problems in the Promotion System that only relied on Sales in conducting sales promotions, Ordering system is still recorded in a piece of paper, Calculation of total sales transactions still use calculator tools and Sales Reports are still recorded in a Sales Book so The researcher wants to Design a Sales Information System Application to solve the problems that exist in the research site. This study uses whitebox and blackbox testing. Whitebox testing is testing with trial techniques on program flow, logic structure and program procedures by flowchart mapping, then calculating the number of edges and nodes. Black box testing method focuses on the functional requirements of the software. Therefore black box trials allow software developers to create a set of input conditions that will train all the functional requirements of a program whether it runs as expected or vice versa. Based on the results of examining Whitebox in one of the processes in this system, namely on the Ordering of bread menu with a balanced yield of Cyclometic Complexity (CC) = 4, this system is stated to work well. While the results of the Blackbox system test can run as expected. Keywords: Information System, Sales, Android, php, html and Mysql.

Abstract

in this study to identify the increase in educational services based on the quality of non-formal education is an indicator, having tiered in terms of education, non-formal education (training) to be one of the prerequisites in multiplying the potential for self-development. Data mining algorithms is a basic k-means clustering to put the object based on the average (Means) nearest cluster. Aims to design mapping information system education with the k-means cluster. Application k-means cluster is part of a non-hierarchical method, the mapping system of education in 171 samples of data Isalam Students Association (HMI) were tested in this study showed that the non-hierarchical method (k-means cluster) has a good degree of accuracy because they specify the number of clusters in advance. Education information system mapping is used to cluster the data level, corresponding formal education and training has been followed. Education information system mapping is used to cluster the data level, corresponding formal education and training has been followed . The test results have in me some real, the spread of the data in each cluster are similar.  At the time of  the iteration process is not visible difference in the results of the mapping study using the k-means cluster. Results of a cluster centroid information models with variable 4 educated members include S1, S2, has entered basic training cluster  0, educated S1, S2, S3 has entered basic training cluster 1, S1 has educated basic training and training of incoming intermediate cluster 2, educated S1 has entered basic training cluster 3. formal education, education tiered seen in cluster 1 for non-formal education  (training) tiered education seen in cluster 2. Based the test results k-means cluster.   Keywords: Information Systems; Educational Mapping; Cluster; K?means
