Penerapan Teknologi WebGL pada Virtual Aquarium Berbasis Tiga Dimensi (3D)
Full text linkVirtual Aquarium is an application which can be used to display an aquarium together with its content that is look like a real one. By using this application, users can see the display of the aquarium like they are looking at the real object because it is displayed in 3D animation. WebGL is one of the technologies that can be used to build this 3D web. It is a canvas context from a HTML element which provides a 3D API graphic object that is implemented into a web browser without using the plug-in. WebGL can provide an interface program for 3D graphic. This new technology use a HTML5 version by accessing the canvas element which then it is accessed by using Document Object Model Interface. As a result, the user can see a Web interface which formerly in 2D, and then it is developed into 3D where the object can be seen from any other sides
Rancang Bangun Sub-sistem Informasi untuk Pencatatan Transaksi di Program Studi Sistem Komputer Undip
Full text linkCurrently in Computer Systems Engineering, Faculty of Engineering, Diponegoro University, Semarang, all records of financial transactions are still using Microsoft Excel and Microsoft Word. It can be assumed that to make a statement of financial performance is very difficult, both statements of cash receipts and cash disbursements report. It should be made a software for reporting financial performance can be monitored by the Head of Department and staff are entitled, at a moment's financial performance reports can be monitored and printed quickly, easily and accurately.This research is conducted by methods such as by literature study, system design and testing of the system. In the literature study used methods of research library of reference books related. The design of this study using a Rapid Application Development (RAD) so easy to develop applications. Applications are also made so easily accessible web-based and maintained (maintenance), because the application is placed on the server side. To secure information from unauthorized users, multi-user application created with the login system.The expected result is a sub-information systems for recording transactions and reporting financial performance can easily monitor and printed at any time needed
Pengukuran Kesenjangan Digital di Institusi Pemerintah Daerah (Studi Kasus: Pemerintah Kota Semarang)
Full text linkThe rapid growth of information and communication technology (ICT) facilitate human activity. Along with this rapid development, emerge a gap between individuals who have access to technology and those whose not. This is what we called the digital divide. The main challenges of e-government development are the ability and readiness of management not only the technology. The skill divide between human resources in the government will certainly affect the implementation of e-government in Indonesia.The purpose of this study was to determine the factors that influence the digital divide between individuals in the government, to measure the condition of the digital divide between the current individual in government
Desain dan Implementasi Web Proxy dan VPN Akses (Studi Kasus di Undip)
Full text linkThe development of computer and network technologies lead many organizations to expand its network. The intranet network is used initially to connect clients with geographically dispersed enterprise networks, but when it is need a more extensive and huge network intranets are not possible anymore, it is necessary development of a secure private network that uses Internet network. Methodology of research for this final task include the study of literature, design systems, and testing of the system. In the literature study used research methods from the literature study reference books that are related. The design of this final task using OpenVPN and Glype Proxy to access the local network from the Internet. Last is the testing of this network system, where in this stage the network system will be tested in order to create a reliable network and secure. The result obtained is a network system that allows users from outside the network can access some or all services available on the local network as still in a network, from anywhere via the Internet. For Internet users to become members of this private network they must go through the process of authentication, the data available on the private network is encrypted so it can not b
Framework untuk Pengembangan Sistem Otomatisasi Menggunakan Programmable Logic Controller
Full text linkNowadays, the programmable logiccontroller/PLC has been a key device in industrial automation. This device has a function to monitor production process and to control its operation automatically. This paper presents a framework to develop this product service-system PLC using opensource softwares. It includes software for PLC hardware development, firmware development and IDE system
Detection of the Breast Cancer from Thermal Infrared Images
No full textThermography can be used as part of an earlydetection tool which gives women of all ages the opportunityto increase their chances of detecting breast diseases at avery early stage. Breast thermography is a noninvasiveprognostic procedure which can predict a tumor growth ratein breast cancer patients. The objective of this research is toacquire the potential of the statistical characteristics of thebreast thermogram images for the detection of the breastcancer.For this research we use thermal data images fromSardjito hospital at Yogyakarta, from normal and abnormalbreast (detected breast cancer). Firstly, download the breastimage thermograms from the InsideIR software of FlukeTi20 and save them as the inputs to our image processingprogram. Then adjust the format of the images, convert tograyscale images, and crop them to separate the suspectedobjects from the background. Finally we tabulated thestatistical characteristics of the objects which are the means,standard deviations, and entropy to reveal the abnormalitiesof breast thermograms.The results show that the method are promising todetect the abnormality on the breast thermogram images.The normal breast thermograms have minimum entropieswhich differ from those abnormal thermograms in the earlystage of breast cancer and thesignificantly from the moreadvanced of breast cancer
