Query optimization in integrated database can’t be separated from data processing method. In order to have faster query response time, a method to optimize queries is required. One of many methods that can be used for query optimization is using fuzzy logic with Tsukamoto inference system. Value set on each variable is defined membership functions and(More)
Solid State Drive (SSD) is a revolutionary new storage technology. Enterprise storage system using full SSD is still very expensive, while hard disk drive (HDD) is still widely used. This study discusses hybrid configuration storage in virtualized server database with benchmark against four hybrid storage configuration for four databases, ORACLE, SQL(More)
The high complexity of the supply chain network and the characteristics of products made supply chain management of agricultural products were more susceptible to the risks emergence of loss. Therefore, it is required to develop a mechanism for price negotiation which distributes the risks fairly for each stakeholder in the supply chain. In addition it is(More)
Collaborative filtering method was widely used in the recommendation system. This method was able to provide recommendations to the user through the similarity values between users. However, the central issues in this method were new user issue and sparsity. This paper discusses about how to use matrix factorization and nearest-neighbour in film(More)
Prediction of future research topics is usually undertaken, especially by policy makers in research environment, to determine the focus of future studies. Analysis of future research topics by using a numerical approach based on scientific publications or patents have been previously done by several researchers mostly by classifying the topics based on the(More)
In developing information system, privacy is an important component that must be guaranteed especially in government system. Indonesian government has introduced universal health care system that adopts Diagnosis-Related Group (DRG). This system is used to increase the service of healthcare providers and integrate patients' data. In Indonesia the universal(More)
Accurate estimating software development effort is essential in effective project management processes such as budgeting, project planning and control. To achieve an accurate estimate some algorithmic estimation techniques proposed to eliminate or reduce inaccuracies estimation. COCOMO is a parametric model used to estimate software effort. However, so far(More)
One of the most important problems in pattern recognition is texture-based image classification. In this paper, the combination of Discrete Cosine Transform (DCT) and Gray Level Co-Occurrence Matrix (GLCM) methods for feature extraction was proposed. The attributes extracted from DCT method were mean and variance, while the attributes extracted from GLCM(More)
