Abstract

Differences in screen size between the desktop screen, tablet and smartphone and the diversity of the number of website columns cause the problem of decrease value effectiveness and efficiency of the website. This problem happens because the layout arrangement is less good when a website has a certain number of column conditions and transformed into a particular device. So it is necessary to rearrange a good website layout by adjusting the number of columns and certain devices. The layout arrangement consists of a website with the number of columns that is one column, two columns, and three columns and the device selected for layout arrangement is tablet and smartphone. The rearrangement of the website layout is derived from the application of Material Design Guidelines (MDG) and User Centered Design (UCD) approaches to find out which approach is better applied for layout arrangement with specific column counts and certain devices to improve the effectiveness and efficiency of the website. The equation of effectiveness and efficiency of Anton Sergeev (2010) is used to determine the increase or decrease in effectiveness and efficiency on website before and after modeled. Based on the results of this study, the MDG approach further increases the efficiency of website time of three columns tablet version. While UCD approach further increase the efficiency of website time one and two columns version of tablets and smartphones and three-column website version of the smartphone.

Abstract

Driving safety is the most important thing in driving on the highway to avoid accidents. Accidents occur due to several factors including lack of concentration while driving, drowsiness, and so forth. One effort to avoid or reduce the risk of accidents when driving is to maintain the distance of the vehicle with the vehicle in front of it. In this study the theme of image processing is used to achieve the goal of maintaining distance between vehicle by utilizing the Histogram of Oriented Gradients (HOG) method as a way of extracting vehicle features which in this case are cars, then classified by the Vector Support Machine (SVM) method to distinguish between car classes and not cars, the two methods are implemented uses a Raspberry Pi camera mounted on the dashboard to detect the vehicle in front of it. When the distance of the vehicle with the vehicle in front is less than or equal to 15 meters (≤15m), the buzzer will sound as a sign that the vehicle is too close. The accuracy of the system in detecting cars using Support Vector Machine (SVM) that based on the Histogram of Oriented Gradients (HOG) feature by testing at a distance of 10 m, 15 m, 20 m, dan 30 m is 81.3% and the testing accuracy of Hardware and Software integration is 87.5%.
