Abstract
Along with the increasing use of computers, business activities and data storage have also begun to be transferred, from the initial use of document files, now changed to computing activities and digital data stored on the computer. The increasing importance of the computer certainly raises its own challenges and risks. One of the risks and challenges is the security of the computer system and network. Various ways have been done to improve computer network security, one of which is using the Intrusion Detection System (IDS). IDS is one of the security management that is able to detect attacks on a computer network in real-time, for example Denial of Service (DoS) attacks. To maximize the IDS detection function that is able to detect unknown attacks, a data mining approach is used to create an IDS that uses anomaly based detection techniques. In this study, a sequential pattern mining technique, the CM-SPADE algorithm, is used to generate IDS rules that can detect DoS attacks. Modeling and rules are made by applying the CM-SPADE algorithm to the KDD Cup 1999 data set. The results of this study reveal that the implementation of the CM-SPADE algorithm is able to produce IDS rules that can detect DoS attacks with an accuracy rate of 97.976%.

Abstract
UMSIDA Eprints is a repository of student and lecturer publication documents at the Muhammadiyah Sidoarjo University (UMSIDA). The collection of documents is still random and the search can only detect from the title keywords. The increasing culture of writing and research makes it possible for more and more documents as literature. Documents in Eprints are grouped by subject provided by the repository manager and grouped by the admin who uploaded the document. Automatic document grouping can be done by grouping documents based on the contents of the document using the Information Retrieval (IR) approach. The retrieval process is carried out by document processing with tokenization to obtain data tokens, the data tokens are processed through a stemming process to obtain the stem value of each word. The stem value is processed using the indexing process and word stem to get sentence indexes through the weighting process. The index results stored in the database become document variables that are the features or characteristics of each document. The index of all documents is grouped through the Kmeans Genetic Algorithm (GA-Kmeans) by determining the similarity of the document or the proximity of the centroid with the index of each data. The cluster data will be in accordance with the groups grouped from the closest distance to the cluster.

Abstract
The high feature space (dimension) is one of the main issues to be considered in the text clustering process. Therefore, various dimensional reduction methods have been introduced in various researches for selecting informative sub feature. Each method of reduction uses a different strategy to select sub feature, and the results are different even if using the same data set. Typically, union methods and intersection methods are used to combine selected sub feature with different reduction methods. The union method selects all feature and intersection only selects the general feature (slices) of the feature under consideration. So, the union approach causes the an increase in feature dimensions and the intersection approach causes the loss of some important feature. Therefore, in order to take advantage of a method and reduce its weaknesses, in this research proposes new approach, i.e modified union. This approach applies the union methods to select top ranking feature and applies intersection methods to the rest of the feature. In this case, feature selection uses the term variance (TV) and document frequency (DF) methods to calculate the relevance value of each feature. The effectiveness of the proposed method is tested on the data set of Hadith Shahih Bukhary. The results clearly show that the proposed method improves clustering accuracy over other methods with DB index is 2.7.
