Abstract

This study aims to examine the factors that influence students’ comfort to participate in the class, and their impact on the objective measure of learning. This study uses an active learning method, which focuses on the case discussions in the management accounting class at Satya Wacana Christian University. This research obtains the data on students' initial habits and perceptions of class discussions through pre and post-test questionnaires. Furthermore, the objective measure of learning was based on students’ marks obtained from lecturers. Three marks were recorded for each student: the final exam, the case discussion, and the class participation marks. Hypothesis testing is done using multiple regression analysis. The test results show that the frequency of student participation in class discussions has a positive effect on the students’ comfort to participate in the class. The result also indicates that students’ comfort and initial GPA have a positive effect on the objective measures of students’ learning.

Abstract

Optimization of data security techniques is very necessary so that the data or information that is secured is really safe from attack. Data that has been encrypted based on cryptographic techniques very quickly raises suspicion that the data is confidential or important. Therefore, this technique is better combined with steganography techniques. Utilization of steganography techniques can minimize the attacker's suspicion of data that is secured, because by using steganography data techniques can be hidden on certain objects. This study discusses how to encode a text based on the Merkle-Hellman Knapsack algorithm and the resulting password is hidden in a grayscale digital image as a hiding object based on the pixel value differencing algorithm. This is done to minimize suspicion and make it difficult for attackers to find out confidential or important data.Keywords: cryptography,steganography, merkle-hellmankanpsack, PVD, image
