Information Dashboard Executive (INDEX) is a visual representation of data in the form of dashboards that are used to get a snapshot of performance in every business process so as to facilitate the executives took a quick response. Pentaho is a BI application is free open source software (FOSS) and runs on top of the Java platform. QlikView is focused on simplifying decision making for business users across the organization. Processing needs to be able to optimize data analysis functions of PDPT is developing an interactive dashboard visualization data. The dashboard will be built using the data pentaho integration as a gateway connecting between database applications with Data PDPT and data visualization are developed by using QlikView. Software development methodologies in application development work is incremental method which is a combination of linear and iterative method with parallel modifications in the process the iterative process so that the project done faster.The results of this study are is the data representation of the modeling query is constructed able to describe the activity / student profiles in a certain semester. The data representations constructed include active distribution per class, per student graduation force distribution, distribution of student status, distribution provinces of origin of students per class, the distribution of the number of class participants, distribution of credits lecturers and distribution of subject.

Decimal Classification

Senayan Library Management System, usually called as SLiMS dan e-DDC (electronic Dewey Decimal Classification), is an application for library that now is used widely because it is easy to use, guaranteed of updating from the provider, and free. SLiMs and e-DDC is actually two separated application, but in the practice, it is possible and recommended to be used together. SLiMS is used as a tool of library automation, meanwhile e-DDC functions to help finding collection classification number. Some users of SLiMS and e-DDC have suggested to develop SLiMS that is integral with e-DDC, so the use of both application can be practical which can make the librarian easier to manage the library. Based on the suggestion, the writer and e-DDC team finally created and designed additional application which is called plugin in SLiMS automation system that contained e-DDC. The plugin was created using PHP MySQL and MySQL database. The purpose of this paper is to enrich the reference of library application development, especially that is based on Free Open Source Software (FOSS). The method used is Research and Development method. The result was the Plugin e-DDC for SLiMS was finished and released on May 2, 2015 to celebrate National Education Day.

AbstractThe article describes how the Structure-from-Motion (SfM) method can be used to calculate the volume of anthropogenic microtopography. In the proposed workflow, data is obtained using mass-market devices such as a compact camera (Canon G9) and a smartphone (iPhone5). The volume is computed using free open source software (VisualSFMv0.5.23, CMPMVSv0.6.0., MeshLab) on a PCclass computer. The input data is acquired from video frames. To verify the method laboratory tests on the embankment of a known volume has been carried out. Models of the test embankment were built using two independent measurements made with those two devices. No significant differences were found between the models in a comparative analysis. The volumes of the models differed from the actual volume just by 0.7‰ and 2‰. After a successful laboratory verification, field measurements were carried out in the same way. While building the model from the data acquired with a smartphone, it was observed that a series of frames, approximately 14% of all the frames, was rejected. The missing frames caused the point cloud to be less dense in the place where they had been rejected. This affected the model’s volume differed from the volume acquired with a camera by 7%. In order to improve the homogeneity, the frame extraction frequency was increased in the place where frames have been previously missing. A uniform model was thereby obtained with point cloud density evenly distributed. There was a 1.5% difference between the embankment’s volume and the volume calculated from the camera-recorded video. The presented method permits the number of input frames to be increased and the model’s accuracy to be enhanced without making an additional measurement, which may not be possible in the case of temporary features.

O desenvolvimento de software é uma atividade intensive em esforço humano. Assim, a forma como os desenvolvedores encaram suas tarefas é de suam importância. Em um ambiente como o usual em projetos de FOSS (free/open source software) em que profissionais (desenvolvedores pagos) compartilham os esforços de desenvolvimento com voluntários, a moral da comunidade de desenvolvedores e usuários é fundamental. Neste artigo, apresentamos uma análise preliminary utilizando técnicas de análise de sentimentos realizada em um projeto de FOSS. Para isso, executamos a mineração da lista de endereços eletrônicos de um projeto e aplicamos as técnicas propostas aos participantes mais relevantes. Embora a aplicação seja limitada, no momento atual, experamos que essa experiência possa ser benéfica no future para determiner situações que possam afetar os desenvolvedores ou o projeto, tais como baixa produtividade, abandono do projeto ou bifurcação do projeto, entre outras.

AbstractHuman genetic variants are usually represented by four values with variable length: chromosome, position, reference and alternate alleles. There is no guarantee that these components are represented in a consistent way across different data sources, and processing variant-based data can be inefficient because four different comparison operations are needed for each variant, three of which are string comparisons. Existing variant identifiers do not typically represent every possible variant we may be interested in, nor they are directly reversible. Similarly, genomic regions are typically represented inconsistently by three or four values. Working with strings, in contrast to numbers, poses extra challenges on computer memory allocation and data-representation. To overcome these limitations, a novel reversible numerical encoding schema for human genetic variants (VariantKey) and genomics regions (RegionKey), is presented here alongside a multi-language open-source software implementation (https://github.com/Genomicsplc/variantkey). VariantKey and RegionKey represents variants and regions as single 64 bit numeric entities, while preserving the ability to be searched and sorted by chromosome and position. The individual components of short variants can be directly read back from the VariantKey, while long variants are supported with a fast lookup table.
