Abstract

A Case study was taken as a research to investigate the physical process occurred in a simple electric circuit which consists of resistance component R and inductance L with direct voltage source. The general form of series circuit is represented a differential equation of the first order to count the current transfer equation can be found by many methods, they are the first ordered solution, Euler method, the third order Runge-Kutta method, and the fort order Runge-Kutta by using Matlab program. The examinationon by using step measurement with h = 0,05 caused error value to the first order solution method = 2.79%, Euler method = 3.8%, the third order Runge Kutta method = 2.1%, the forth order Runge Kutta method = 2.26%, using step measurement h = 0.1 caused error value to the first order solution = 2.27%, Euler method = 5.23%, the third order Runge Kutta method = 2.27%, the fourth order Runge Kutta method = 1.85% and using step measurement h = 0,15 caused error value to the first order solution = 5.81%, Euler method = 22,35%, the third order Runge Kutta method = 7.19%, the forth order Runge Kutta method = 4.7%.

Abstract

Expert system for analysis of disease in rice is a computer-based system for analysis and diagnosis of diseases in rice based on the symptoms that are displayed on the search process. System design goal is to help farmers to know the type of disease in rice plants as well as instructions given solution and the solution given by an expert.Design of an expert system was built using the method of forward chaining in which the searches performed with the technique in detail and the detail so that the search process is obtained as solutions of the selected problems.Advantages of this method is the description of the algorithm and a knowledge base that is comparable to the analysis of the problem, so the results given the results obtained in the order and detail. Expert system for analysis of disease in rice plants created uses programming language Delphi 7.0 with MySQL. By using an expert system is expected to acquire the system user the ease in obtaining the information needed regarding the analysis and diagnosis of disease in rice.

Abstract

The development of information technology is currently very rapid, can be seen in the real world how important the use of video, such as in the field of advertising, entertainment, business and no less important in the field of education for the delivery of learning information which all require a clear and attractive display. In this study, we will examine a comparison of three video software on image quality, image sharpness, brightness and audio effects in Windows Live Movie Maker, VideoSpin and Movavi Video. The research conducted made the video using the three software on the NTSC video format, AVI file type, resolution (720x480), 4:3 Pixel ratio, Standard D1 aspect ratio (0.09), 1500 kbps bit rate, 29.97fps frame rate with Audio: Stereo Channels, 48,000 HZ sample rate, 2.2 minutes duration. The samples were taken by the HMJ activities (HIMAKOM), namely graphic science competitions, sports, the introduction of new software training students, data used by static photos. For testing, questionnaires were collected on 43 respondents, students, majoring in Computer Systems and Statistics to assess the results of the video from the three video software and then tested with Anova to find out which one was better. From the results of the calculation of respondents' data, the average respondents liked the Movavi Video software with an image quality value of 89.2, sharpness of images 88.103, audio effects 83.333 and after being tested using Anova software Movavi Video analysis was better. It was concluded in this study that Movavi Video software could be a consideration to choose from in making videos.

Abstract

Nowadays, the fast technology development asked everyone who is able to pro-active in information technology, especially in information system development based on web. Information which is completed by visualization and animation can be easier understood by users. Interactive website is made to make easier the introduction and improvement of tourism interest in Bantul by using Macromedia Firework application program that is used for animation, programming language for PHP and data base server using MySQL ,Adobe Photoshop is used for picture editin. This interactive website is Bantul tourism communication media that based on web. It is able to make easier for all tourism stakeholders to know, to be familiar with, to understand data and Bantul tourism characteristics will be easy to be accessed by stakeholders or tuorists, both foreign and local tourists. The result of making website is to increase the numbers of tourists who visit to Bantul, this caused the increasing of society prosperity, especially society around tourist resort. The activities of tourism included souvenir, stall, special food, culture, transportation and labors

Abstract

Representasi objek 3D dapat dilakukan dalam beberapa cara diantaranya menggunakan teknik rendering ray-tracing dan Radiosity. Radiosity dan ray-tracing adalah teknik rendering untuk menampilkan citra 3D pada layar tampilan 2D yang mensimulasi perjalanan sinar cahaya yang bergerak di dunia nyata. Dalam dunia nyata pancaran sinar dari sumber cahaya akan mengiluminasi permukaan objek. Dalam artikel ini dibahas representasi 3D dengan teknik rendering ray-tracing dan radiosity pada objek bola, kerucut, dan box. Objek berada di luar dan di dalam ruangan. Setelah objek dipilih, permukaan objek yang akan dimunculkan pada display diberi efek pencahayaan dengan teknik rendering ray-tracing dan radiosity. Selanjutnya dianalisis perbedaan dan kesamaan hasil rendering objek menggunakan perangkat lunak POV-Ray. Hasil analisis objek 3D yang tersusun di dalam ruangan adalah kecepatan rendering menggunakan teknik ray-tracing sebesar 2,15 detik dan radiosity sebesar 12,42 detik. Proses rendering objek menggunakan teknik radiosity memerlukan memori lebih besar dibandingkan ray-tracing.
