The implementation of information and technology with literacy is known as digital literacy. Digital literacy not only talks about the skill or competency of using technology as a teacher in the learning process, but how school as a formal education institution can help the students to have digital literacy competency since this skill is needed by the students and teachers who are imposed by the technology as an impact of the pandemic. Schools not only have a responsibility to educate students about digital literacy competency in the learning process, but in all the school aspects must support the implementation of digital literacy. This research wants to explore how digital literacy competency has been implemented at senior high school level in Indonesia. Therefore, this descriptive qualitative research objective is to explore the digital literacy competency implemented at Citra Kasih School in Indonesia. The data collection techniques used in this research were observing and interviewing the principal by asking questions that had passed the validity test. Following the digital literacy competency which was set by Indonesian Ministry of Education and Culture (2017), this research explored the implementation of digital competency into three bases, class based, school environment based, and community based. From the research, it can be concluded that Citra Kasih Senior High School has applied three bases of digital literacy competency indicator at school. In the class based, Citra Kasih Senior High School has attended digital literacy training, applied and utilized digital literacy, and understood how to use digital media and the internet. Based on the school environment Sekolah Citra Kasih High School has implemented digital literacy in reading references, book borrowing frequencies, school activity, school policy. School service, and information presentation. However, on community based, Citra Kasih Senior High School has implemented digital literacy in facilities and infrastructure and in the involvement of parents and institutions.</p> Floren Agnesia Sinaga Ratna Dewanti Darmahusni Copyright (c) 2021 Floren Agnesia Sinaga, Ratna Dewanti, Darmahusni https://creativecommons.org/licenses/by/4.0 2021-09-22 2021-09-22 8 9 1 8 10.29121/ijetmr.v8.i9.2021.1026 THE EFFECT OF LEVERAGE, FIRM SIZE, AND SALES GROWTH ON INCOME SMOOTHING AND ITS IMPLICATION TO THE FIRM VALUE (STUDY ON STATE-OWNED COMPANIES LISTED IN INDONESIA STOCK EXCHANGE 2016-2019) https://www.granthaalayahpublication.org/ijetmr-ojms/index.php/ijetmr/article/view/IJETMR21_A08_2638 <p>The purpose of this research was to determine the effect of leverage, firm size and sales growth on income smoothing and its implication to the firm value. The population used on this research was 24 state-owned companies listed on Indonesia Stock Exchange. The samples were determined using purposive sampling method and there were 19 companies which selected as the samples. The analytical method used on this research was statistic descriptive and panel data regression and use Eviews 9 for data processing. The result of this research showed that leverage which measured by debt to equity ratio has negative and insignificant effect on income smoothing while firm size and sales growth have negative and significant effect on income smoothing and income smoothing itself was found to have positive and significant effect on the firm value</p> Sri Mulyati Bambang Mulyana Copyright (c) 2021 Sri Mulyati, Bambang Mulyana https://creativecommons.org/licenses/by/4.0 2021-09-22 2021-09-22 8 9 9 18 10.29121/ijetmr.v8.i9.2021.1015 DIVERSITY AES IN MIXCOLUMNS STEP WITH 8X8 CIRCULANT MATRIX https://www.granthaalayahpublication.org/ijetmr-ojms/index.php/ijetmr/article/view/IJETMR21_A09_2656 <p>In AES MixColumns operation, the branch number of circulant matrix is raised from 5 to 9 with 8´8 circulant matrices that can be enhancing the diffusion power. An efficient method to compute the circulant matrices in AES MixColumns transformation for speeding encryption is presented. Utilizing 8´8 involutory matrix multiplication is required 64 multiplications and 56 additions in in AES Mix-Columns transformation. We proposed the method with diversity 8´8 circulant matrices is only needed 19 multiplications and 57 additions. It is not only to encryption operations but also to decryption operations. Therefore, 8´8 circlant matrix operation with AES key sizes of 128bits, 192bits, and 256 bits are above 29.1%, 29.3%, and 29.8% faster than using 4´4 involutory matrix operation (16 multiplications, 12 additions), respectively. 8´8 circulant matrix encryption/decryption speed is above 78% faster than 8´8 involutory matrix operation. Ultimately, the proposed method for evaluating matrix multiplication can be made regular, simple and suitable for software implementations on embedded systems.</p> Yan-Wen Chen Jeng-Jung Wang Yan-Haw Chen Chong-Dao Lee Copyright (c) 2021 Yan-Wen Chen, Jeng-Jung Wang, Yan-Haw Chen, Chong-Dao Lee https://creativecommons.org/licenses/by/4.0 2021-09-25 2021-09-25 8 9 19 35 10.29121/ijetmr.v8.i9.2021.1037
