The Human Development Index (HDI) is very important in measuring the country's success as an effort to build quality of life people a region, including Indonesia. government needs make groupings based on city/district. To facilitate data grouping similarity existing characteristics, it necessary have method, namely clustering technique. There are several algorithms that often used techniques, K...

Web-based interorganizational workflows need efficient time management. Variations of activity durations and branching distributions on or-split nodes make it necessary that we treat time management in workflows in a probabilistic way. We introduce the notion of duration histograms for capturing the available temporal information about workflow execution, define the necessary operations for com...

Social Comparison is important as it can be either encouraging or discouraging for the person who makes it. Although studies concerning social comparison in the classroom context abound, few deal with the relationship between the role of social comparison orientation and tendencies in academic achievement in a competition based educational context. Adopting a non- experimental ex-post facto des...

We describe a programming tutor framework that consists of two configurable components, a guided-planning component and an assisted-coding component that offers task relevant automatically-generated hints on demand to students. We evaluate the effectiveness of the new integrated planning and coding environment by comparing it to three other tutor conditions: planning-only, coding-only, and plan...

In knowledge work, different types of collaboration can be distinguished. Because of close relationships between these collaboration types, it is necessary to support them together in an integrated collaboration environment. Using case studies, in this paper, the authors describe various types of collaboration practice and demonstrate the necessity of their integrated support. Based on this wor...

Contemporary thinking on organizational capability has been profoundly influenced by the resourcebased view of the firm (Barney, 1991; Eisenhardt & Schoovenhover, 1996; Peppard & Ward, 2004). The proponents of this view argue that firms possess costly-to-imitate capabilities (i.e., unique configurations of resources) that are regarded as the fundamental drivers of superior performance (Bharadwa...

In general, the process of collecting and grouping data requires a long process. And if it has to be grouped manually takes very time. Therefore, mining is solution for clustering - lot classify it. this research conducted at CV.Togu Togu On Medan Branch, applied using K-Means model C4.5 algorithm which provides standard in various fields used classification because results method easy understa...
