Abstract

Ray tracing is a technique in computer graphics that produced image by traversing ray from eye to every pixels on screen, and then the intersection checks between ray and objects are done. Ray tracing can produce a photorealistic image, but needs a long time to do the computations. One of the ways to shorten the computation time is by reducing the number of intersection checks between ray and objects. One of the popular methods is Bounding Volume Hierarchy (BVH).In this application, Compute Unified Device Architecture (CUDA) is also used beside BVH. The CUDA’s usage purpose is to reduce computation time by doing parallel computing in the GPU. Computations done in GPU are computing ray directions from eye to every pixels and color of every pixels.The result of this application is more than 70% rendering time reduced when compared to ray tracing application with only BVH. The maximum reduction is 86%.

The advantage of this application is in addition to tell the story to the people, this application also has mini games that people can play. Several mini games contained in this application uses a sensor in android device which is an accelerometer sensor which serves to capture the acceleration of gadget. This folklore application is an application-based learning with mobile devices designed with Java and compiling assisted by Android Studio.The application development is intended to increase public interest in the Cindelaras folklore and as well as a medium of learning for children about moral and ethical values.

Abstract

In the past few years, Big Data has been a trend in the world of Information Technology. Alongside the growth of organizations, the bigger the data that is owned, some can reach the scale of Terabytes to Pentabytes. When an organization wants to do an analysis of a Big Data it takes time due to limited CPU and memory. To overcome this, there is a paradigm which is called distributed computing. There are many tools that aim to cultivate Big Data such as Apache Hadoop, Apache Spark, and etc. However, the tool that is going to be analyzed is the Apache Hadoop.The adoption rate of Big Data in Indonesia is 20% for 2 to 3 years into the future [1]. Seeing these facts, more and more companies are planning to adopt Big Data to analyze their data. Due to the increasing use of Big Data and Apache Hadoop, it is conducted an exploratory analysis of data correlation on Apache Hadoop. In addition, testing was also done using the Apache Hadoop with varying number of nodes, mappers and reducers, and number of different block sizes [10].Exploratory analysis of data correlation on Apache Hadoop is done by making four types of data analysis applications, namely two applications correlation values for the data search Yahoo! Messenger and two applications for creating classification trees. Based on test results obtained that the R application is more suitable for smaller data size while Hadoop is more suitable for large data size. For large data, application R uses higher percentage of CPU and memory than Hadoop. The combination of mapper and reducer that will provide the most optimal execution time is for mapper in the range of 2/3 of the total CPU cores, while the reducer is 1/3 of the total CPU cores.

Abstract

Banknote can’t be detected and recognized by blind people.Application for banknote recognition, which can run on Androidsmartphone with camera, is made in this paper to help blind people.Indonesian Rupiah(IDR) is used as a working example. This doesnot require any communication with remote server, and all thenecessary computations take place on the phone itself. In thisapplication, user can tak picture of the banknote with double tapon the screen, and the results will be announced by voice. Thesystem relies on computer vision algorithm, such as featuredetection, feature description, and matching. Each application ofORB, SURF, and SIFT is applied in matching captured banknoteimages to template images. To improve the confidence of thebanknote recognition, homography is used to filter the featurematching results.The systems evaluate the performance on 700 images and report anaccuracy of 93.14% using SURF, 92.57% using SIFT, and 89.17%using ORB
