Abstract

Sign language learning application to be able to help its users in order to learn sign language easily namely a sign language dictionary application can display video in it, is needed these day. The popularity of using android operating system in the general society makes the development of Indonesian sign language dictionary application based on android. This application development is using the software development waterfall model that consists of a stage needs analyze includes an analysis of user needs, preparation tools and the materials development, system design in the form of use case diagrams, activity diagram, sequence diagram, as well as interface design, coding by using the Java programming language, to the testing of products include the black-box test, experts test, and users test. The result of this application development is a dictionary application of sign language that can display a video of Indonesia language sign movement. Black-box testing result showed the application was already running in accordance with the design that has been created. Testing applications by material and media experts indicated that this application has a very good quality. Also for the application user testing results conducted 22 people studied the sign language, they indicated that the application has a very good functional qualities. Based on the results of these tests, then it can be inferred that Indonesian sign language dictionary application development can be used as a learning tool for helping Indonesian people to study about the sign language.

Abstract

This aim of this research to create a clone hardware that can represent original Bonang Barung using existing technology. Capacitive sensors on Arduino was used to detect a touch on bonang. The touch was distinguished by the declaration pins of Arduino. Each pin represented one sensor for one tone. The tone was derived from recording original Bonang Barung stored in SD-Card WTV020SD-16P module. Furthermore, Arduino as microcontroller would select input to produce an output through the speakers. Testing was done by analyzing the frequencies and sensitivities that exist in electronic bonang. Results of the test were showed difference frequency of 1-9 Hz between the frequency of original bonang with electronic bonang. This difference was still relatively the same frequency in one tone. The use of different thickness metal in sensitivity testing was as good as the response from the sensor. On the use of resistors, the higher value of resistor would make higher sensitivity of the sensor. Based of the research could be concluded that the capacitive sensor could be applied to design electronic bonang by using appropriate resistor value that was 1 MW. The higher value of resistor would make sensitivity of electronic bonang higher too. The use of aluminum foil and aluminum plate with thickness 0.8mm, 1mm and 1.5mm with each side lengths 3cm, 4cm and 5cm were as good as for sensor response.

Abstract

The purpose of this study was to determine the effect of the application of problem solving learning model to increase learning outcomes of ICT in class VIII SMP Negeri 1 Ulujami. The method used is a method of quantitative experiments. The population in this study were all students of class VIII SMP Negeri 1 Ulujami the academic year 2015/2016 with the number of 364 students. The research sample is chosen randomly selected classes are two classes as class ekserimen (VIII-A and VIII-G) and two classes as the control class (VIII-C and VIII-I). The results showed the average posttest experimental class learning model of problem solving that is class VIII-A is 86 and VIII-G is 86, while those using the lecture method on the control class is class VIII-C is 79 and VIII-I was 83. the results of the study concluded that there are significant learning model application problem solving to learning outcome of ICT on students of SMP Negeri 1 Ulujami. It can be seen from the results of the linear regression equation VIII-A is ý = 0.29 + 63,79X and the results of the linear regression equation VIII-G is ý = 0.57 + 40,91X means that the effect of variable to variable pretest posttest is positive, showing a rise of the value pretest will be followed by a rise in the value of the posttest.

Abstract

English is an international language that is needed in the development of global information technology. Each persons English skills can be measured by a test called TOEFL. TOEFL (Test of English as a Foreign Language) is a test oriented to American English. The English test used in the eucation world is the TOEFL ITP (Institutional Testing Program) because it focuses on a particular institution. Currently, there are many universities that use TOEFL ITP as one of the requirements of graduation that is adjusted to the standards of each university. Currently many agencies provide services to study and practice TOEFL at a cost that is quite expensive. In this study made alternative implementation of TOEFL simulation to learn, practice and perform TOEFL simulation through android smartphone. The results showed the validation and validation category of the media, the TOEFL ITP simulation application included in the category very well. The effectiveness test obtained Sig. (2-tailed) less than 0.05 ie 0.012 and 0.002 with average Sig. (2-tailed) is 0.007. Test results of 82.5% outcome result results with very good category. So it can be concluded that the application called TOEFL OS enthused by the user and has been appropriate user needs as an alternative learning media TOEFL.
