Abstract

Keamanan data pada suatu citra merupakan salah satu hal penting di era teknologi informasi dan komunikasi. Untuk dapat menjaga keamanan data pada suatu citra dapat menerapkan teknik kriptografi untuk menyamarkan Region of Interest (ROI) citra digital agar layak dilihat masyarakat umum. Penelitian ini bertujuan untuk merancang dan mengembangkan sebuah aplikasi kriptografi yang mengimplementasikan algoritma Data Encryption Standard (DES). Untuk penyembunyian koordinat ROI citra digital digunakan algoritma steganografi Least Significand Bits (LSB). Implementasi Algoritma DES pada aplikasi kriptografi ROI citra digital menghasilkan sebuah perangkat lunak yang disebut dengan DESROICitra. Berdasarkan hasil pengujian perangkat lunak diperoleh bahwa DESROICitra mampu mengenkripsi ROI citra dengan baik. Tampilan ROI citra asli setelah dienkripsi sangat berbeda sehingga tidak mungkin untuk dikenali lagi. Perangkat Lunak DESROICitra dikembangkan dengan menggunakan Bahasa pemrograman Delphi 7.

Abstract

The study aimed at finding out (1) the effect of self regulated learning (SRL) model towards learning achievement in communication and information technique of the students class VIII SMP Negeri 1 Banjar, (2) students motivation towards the implementation of SRL model, (3) students’ responses towards the implementation of SRL model.It was a quasi experimental study employing a Post-test Only Control Group  Design. The population of the study were all students class VIII SMP Negri 1 Banjar in 2011/2012. The study involved a number of 65 samples consisting of students in class VIII-C and VIII-E. Class VIII-C became an experimental group, while class VIII-E as a control group. There were two different variables in this study, those are (1) independent variable: SRL model, and (2) dependent variable: motivation and student learning achievement. The data were collected by using multiple choice achievement test to measure the cognitive domain, as well as psychomotor test to measure the psychomotor domain. The data then analyzed by using prerequisite test involving normality, homogeneity, and t-test. While in terms of response and motivation, questionnaires were used.The findings indicated that (1)  there was a significant  effect of self regulated learning (SRL) model of the students. The average score of the students joining direct instruction was 32.02 with standard deviation of 2.92, and the average scores of the students joining SRL model was about 38.50 with standard deviation of 2.33. It indicated that students joining SRL model got higher scores than those a direct model, (2) students motivation average value of the students during the implementation of SRL model was about 72.15, with a percentage of final session of about 21.88% with very high motivation, 68.75% with high motivation, and 9.38% with average motivation. (3) the average value of students’ responses as about 79.63 with  25% of very positive responses, 65.63% of positive responses, and 9.38% of sufficiently positive responses towards the implementation of SRL model.

Abstract

This study aimed at (1) designing and implementing the development of TAIbased interactive learning media for the technology of information andcommunication subject with the topic of graphic design for grade XII students ofSMAN 1 Sukasada; (2) knowing the students and teachers’ response towards thedevelopment of TAI based interactive learning media for the technology ofinformation and communication subject with the topic of graphic design.This study was in the form of Research and Development/ R&D with the designdeveloped by Dick and Carey. It involved the students from SMAN 1 SUKASADAin the academic year of 2011/2012. The data were taken from interview. The validityof TAI based learning media as well as students and teachers’ responses werecollected through questionnaire. The data were then analyzed descriptively.Waterfall model was used in the development of TAI based learning mediawhich was designed by using DFD (Data flow Diagram). It was also implemented byusing Adobe Dreamwaver CS3 software. The result of students’ response analysisshowed that 9% of the students gave extremely positive response, while 87% studentsgave positive response and 4% of the students gave less positive response. Therewere no students who gave negative or extremely response to it. The students’average score was 65, 78 points. It showed that the students’ response to thedevelopment of TAI based learning media was in the positive level. Meanwhile theresult of data analysis on the teachers’ response showed that 100% of the teachergave positive response to the development of the media.Key words: interactive learning media, cooperative, TAI (team assistedindividualization)
