Abstract

Information Technology Infrastructure Library (ITIL) provides a range of processes models and best practice functions as a guide in the alignment of IT and business process. Service Desk is the main function in ITIL to manage and handle all Incidents and Request from users of IT services. One of the main problems encountered in the implementation of Service Desk is the fact that some users are requesting IT services without following the procedure, they ask for help directly to IT personel. This study attempts to minimize those problems by designing Service Desk application using User Centered Design method. Users are expected to be able to use this application with ease and without constraints, thus leading to an increase in the active role of users in the Service Desk. This research was conducted in the PT. Bakrie Telecom Tbk. Application design on this research was done using WSDM (Web Site Design Method). Application design was tested based on three aspects, Navigation Quality testing, Navigation testing using a Test-Case, and testing user response through a survey. The test results prove that the overall design of Service Desk applications built using User Centered Design method have a better usability, making it more attractive to users and is expected to increase the participation of users in the Service Desk.

Abstract

E-government (e-gov) classified into four levels, the first is information publication through the website, second is interaction between society and government. The third is transactions between the community and government and the fourth is integration of all government offices. Service Oriented Architecture (SOA) is framework that has properties of loosely coupled, highly interoperable, reusable, and interoperability. It has potential connecting diversity of platforms without make changes to the application and the database that already exists. Currently Sidoarjo has e-gov first level and most depart-ment/agency already has applications and databases, but it can’t communicate with each other because of diversity of appli-cations/platforms. The study aims build prototype of e-gov third level by increasing cohesion between services and the interope-rability of data/applications. The research used Shared Service Life Cycle (SSLC) method, consists of business process identi-fication, analysis, design and development, and evaluation. The study produced a prototype e-gov third level SOA-based that has cohesion between services and the interoperability of data/appli-cations.

Abstract

One important aspect that is needed to determine the successful implementation of a system is the evaluation. Evaluation is one important aspect that is needed to figure out the successful implementation of an information system. This study aims: (1) to evaluate the use of System Paperless Office in University Gadjah Mada by using Delone and Mclean, (2) to proceed the survey data by using Partial Least Square (PLS) software for measuring user perceptions of the PLO. The data which have been collected are primary data by using questionnaires that has to be fulfilled by Gadjah Mada University employees of three faculties. Moreover, they have to be PLO users who actively use this system. The variables used are the system quality, information quality, service quality, user satisfaction, individual impact and organizational impact. The results of the survey indicate that PLO as a system has not been fully used by all PLO users. Some factors that hinder the utilization of PLO are the lack of information and system quality, so the users cannot maximize the advantage of the PLO. It also affects to the value of utility PLO.

Abstract

Visual reconstruction and modeling of three dimensional (3-D) object is an emerging research topic in computer vision and photogrammetry fields. Nowadays, many commercial products are developed to obtain 3-D model of rigid object, starting from small ancient heritages to city landscape. Such commercial tools are very expensive and not accessible for education and research purpose. This paper aims to present a low-cost approach to generate a 3-D model from geometry of multiple two-dimensional (2-D) images using consumer-level Digital Single Lens Reflection (DSLR) camera. Direct Linear Transformation (DLT) algorithm was used to obtain 3-D point cloud. Texturization of 3-D object was generated by implementing Convex Hull and Random Sample Consensus (RANSAC) algorithms. Experimental result of small Merlion Singapore statue and large Herz-Jesu building shows that the proposed low-cost method is able to visually reconstruct small and large objects by using 10-20% feature points detected on 2D images.

Abstract

ZigBee standard can be used in wireless sensor networks (WSN) with a mesh topology. WSN which formed WPAN that uses ZigBee standard has the capability to thousands of WSN devices can be combined in a single WPAN. With that ability need to do testing WPAN performance parameters to get the number of WSN devices for the best performance in mesh topology. Using simulation program, the research measure throughput, traffic (sent, receive and drop), delay and hop number parameters. Testing about the influence of the number of WSN devices is done by running a simulation of the 20 kind WPAN where every WPAN has one WSN gateway and the number of WSN devices ranging from 5 and increasingly by 5 to reach the 100 WSN devices in a single WPAN. The results showed that WPAN performance with ZigBee standard in mesh topology has the best conditions when the maximum number WSN devices achieve 20 WSN devices.

Abstract

The usual configuration of a UPFC consists of two voltage source converters, which are connected through a common DC link capacitor. One converter is connected in shunt and the other is in series to transmission line in a substation. UPFC is normally located on a transmission network requiring reactive power, with the primary duty to be power flow control. The secondary function could be transient stability improvement due to their rapid response. This research aims to investigate the dumping function of UPFC in coordination with Power Oscillation Damping (POD) Controller in Single Machine Infinite Bus (SIMB) with Power System Stabilizer (PSS). The presence of UPFC in the existing system equipped with both conventional controller and PSS in the generator, could lead to get a dynamics and stability system improvement, a precise adjustment of these controller parameter of POD has been carried out in order to get a good and appropriate set of parameter value.
