Abstract

Watermarking sebagai salah satu cabang dari ilmu steganography yang merupakan teknik penyisipan data atau informasi yang bersifat rahasia ke dalam media data digital lainnya.Watermarking merupakan salah satu solusi untuk melindungi hak cipta yang merupakan suatu teknik penyisipan (embedding) informasi ke dalam media data digital seperti citra, teks, audio dan video secara rahasia.Pada penulisan ilmiah ini dibuat suatu aplikasi watermarking menggunakan metode Least Significant Bit (LSB).Tahapan yang dilakukan untuk membuat aplikasi ini adalah melakukan analisa kebutuhan aplikasi, perancangan menggunakan UML dan struktur navigasi, serta pembuatan aplikasi dan pengkodean mengunakan MATLAB R2010a.Hasil uji coba aplikasi ini memungkinkan pengguna untuk menyisipkan watermark ke dalam gambar digital yang dapat berupa teks maupun gambar untuk mengamankan gambar digital. Pada gambar digital yang berekstensi .png dan .bmp metode Least Significant Bit (LSB) yang dalam proses watermarking tidak membuat adanya perbedaan yang signifikan antara ukuran gambar asli dengan ukuran gambar yang dihasilkan, sedangkan pada gambar asli yang berekstensi .jpg proses watermarking membuat perubahan ukuran yang signifikan karena adanya perubahan ekstensi pada hasil gambar. Kata kunci: Gambar Digital, Least Significant Bit, MATLAB, Watermarking

Abstract

The objective of this research is to describe effectiveness of the learning model of problem solving in improving communication and inference skills in buffer and hydrolysis lesson. Samples in this research were students of State Senior High School 1 Tumijajar of classes XI Sciences 2 and XI Sciences 3 even semester School Year 2011-2012 that have equal academic abilities. This research used a quasi experiment method with Nonequivalent Control Group Design. Effectiveness of the learning model of problem solving was measured by significant differences in control class and experiment class, shown by significant gain. Based on the results of this research, average value of N-gain for communication skills in control and experiment class were 0,53 and 0,65; and average value of N-gain for inference skills in control and experiment class were 58 and 0,66. Hypothesis testing in this research used test two average different with t-test.  Hypothesis result test show that class that used learning model of problem solving had higher communication and inference skills than class with conventional learning model. This indicated that learning model of problem solving was effective to improving communication and inference skills in buffer and hydrolysis lesson.  Keywords: learning model of problem solving, communication skills and inference skills

Abstract

This research is a descriptive study with the aim to produce a model of planning for therecruitment and training of the institution in creating a professional labor export. The methodologyused by the technique of collecting data through surveys, koesioner, and interviews, the sample isprospective migrants who apply through the recruitment agency in West Sumatra. The resultswere obtained that the model include the need to pay attention to the existence of recruitment, thecharacteristics of the workers, paperwork / documents TKI, giving skills / expertise of workers andthe provision of debriefing Final Departure (PAP) before workers dispatched. From the analysisconducted that models used give a significant effect of more than fifty percent. This means that thismodel should be applied against those involved in sending workers abroad, namely recruitmentand skills training institutes place. As for the government of this model can be used as a referencein making a policy in sending workers abroad in order to minimize problems abroad.

Abstract

This study examines the influence of the quality of education and skills of prospective Indonesia Labor from West Sumatra on income. Wage income is expected equivalent to the level of wage labor which comes from other countries. Therefore, in order to obtain equal wage, prospective Indonesian labors sent abroad should be a good level of education, skill trained so that labor productivity increased. The method used in this study is Test Crosstab, and, Chi Square test to see the effect between the two variables used. It is shown that Indonesian labors do not able to compete in terms of quality of education and skills, compared to foreign labors, so that the income received by the Indonesian labor is lower. In addition, professional job that has been chosen by the Indonesian labor is the operator, profession which does not necessarily require a high level of educational and skills qualifications.
