<![CDATA[The purpose of this paper is to develop an e-voting security system using a cryptographic hash function and the one-time pad algorithm. The security of e-voting system is applied through the fulfillment of the five aspects of information security that consist of confidentiality, authentication, data integrity, availability and non-repudiation. The implementation of e-voting security system is done by encryption the voting result. The encryption process is divided into two steps. First, by hashing the voting results using SHA-256 hash function then the hash value stored in the database. Second, by encryption the voting result using one time pad algorithm, this algorithm encryption process by performing XOR operation on plaintext and key that are generated using a random number generation approach. And then the description of the OTP algorithm is hashed using SHA-256 hash function. Both of hash value then compared, if it give a same value then the ballot is considered valid and safe from attacks during the transfer process to the server. This paper successfully meets five security aspects of e-voting system through the implementation of login system for confidentiality aspect, time validation and voters validation for authentication aspect, the encryption process during the elections for data integrity aspect, vote counting for availability aspect and time record for non-repudiation aspect.]]>

<![CDATA[In this study the author tries to compare two models that guided inquiry learning and guided discovery learning. The subjects were three classes in junior Kesatrian 1 Semarang selected by purposive sampling, with details of the two classes of experiments is to apply the model guided inquiry with guided discovery learning in both classes, while classes only used as a control class. To find out improving student learning outcomes The author provides the initial test (pre-test) and final test (posttest). Based on analysis of survey data using t-test and classical completeness. The results of this study indicate that both modes give rise to learning outcomes with the acquisition of the t-test as follows, for a class of guided inquiry thitung 12.017> t table 1.994 (a significant difference), class guided discovery thitung 11.142> ttabel 1,994 (there is a difference significant). From the analysis it can be concluded that both the model can improve student learning outcomes. Then from these two models turned out to be a model guided inquiry further improve student learning outcomes when compared with the model of guided discovery learning. It can be seen from the acquisition value of classical completeness these two classes, namely guided inquiry 83.33% and 77.77% guided discovery learning.]]>

<![CDATA[This study aims to determine the increase in student learning outcomes SMPN 2 Ungaran through the application of Practice Rehearsal Pairs learning strategies on the subjects of ICT Class VIII Junior High School 2 Ungaran. This research is classified as quasi-experimental research with Nonequivalent Control Group Design. The population in this study are all students of class VIII SMPN 2 Ungaran totaling 298 students. Samples were taken by purposive sampling with F VIII class as the experimental class and I class VIII as the control class with the number of 68 students. Data were analyzed using independent sample t-test test and n-gain test. The results showed that increased cognitive achievement of students in the experimental class is greater than the control class with n-gain experimental class > n-gain control class with 0.74> 0.62. In addition, there is an increased learning outcomes in the affective and psychomotor aspects of the experimental class larger than the control class. This shows that Practice Rehearsal Pairs learning strategies better than conventional learning. Suggestions based on the achievement of the implementation of Practice Rehearsal Pairs learning strategies in the learning process which can be used as an alternative in implementing learning in school and to the subsequent researchers to further develop the application of learning strategies Practice Rehearsal Pairs on subsequent learning process.]]>
