Data Security Using Color Image Based on Beaufort Cipher, Column Transposition and Least Significant Bit (LSB)

One of cryptography algorithm which used is beaufort cipher. Beaufort cipher has simple encryption procedure, but this algorithm has good enough endurance to attack. Unauthorized people cannot break up decrypt without know matrix key used. This algorithm used to encrypt data in the form of text called plaintext. The result of this algorithm is string called ciphertext which difficult to understood that can causing suspicious by other people. Beaufort cipher encryption tested with avalanche effect algorithm with modified one, two, three and all key matrix which resulting maximum 31.25% with all key modification so another algorithm is needed to get more secure. Least Significant Bit (LSB) used to insert ciphertext created to form of image. LSB chosen because easy to use and simple, just alter one of last bit image with bit from message. LSB tested with RGB, CMYK, CMY and YUV color modes inserted 6142 characters resulting highest PSNR value 51.2546 on YUV color mode. Applying steganography technique has much advantage in imperceptibility, for example the image product very similar with original cover image so the difference can not differentiate image with human eye vision. Image that tested as much ten images, that consist of five 512 x 512 and five 16 x 16 image. While string message that used is 240, 480 and 960 character to test 512 x 512 image and 24, 48 and 88 character to test 16 x 16 image. The result of experiment measured with Mean Square Error (MSE) and Peak Signal Ratio (PSNR) which has minimum PSNR 51.2907 dB it means stego image that produced hood enough. Computation time calculation using tic toc in matlab resulting fastest value 0.041636 to encrypt 2000 character and the longest time is 4.10699 second to encrypt 6000 character and inserting to image. Amount of character and amount of multi algorithm can affecting computation time calculation.

Extension Mechanism of Overlay Network Protocol to Support Digital Authenticates

Zero-trust security is a new security model that has recently received much attention. Since the model protects all resources, continuous authentication and authorization of resources are mandatory. Many enterprises currently use cloud systems to manage their resources and provide service. On the other hand, IoT systems typically require cooperation service among IoT devices. As a solution for redundant routes and load on the cloud, a peer-to-peer type system is a good candidate. On the contrary, it requires zero-trust security because each device should guarantee security. Since the authors have proposed and developed CYber PHysical Overlay Network over Internet Communication (CYPHONIC) as a fundamental technology to realize zero-trust security, this paper introduces Public Key Infrastructure (PKI) into CYPHONIC. It proposes an extended device authentication scheme and a key exchange mechanism using digital certificates. According to the PKI mechanism, a certification authority authenticates the system and its authenticity of system, allowing communication with the correct communication partners. The proposed extension performs mutual authentication with digital certificates at the start of communication and secure encryption key exchange for communication between endpoints. We develop the proof of concept of the proposed scheme to confirm the adequacy of the extended mechanisms.
Disruption as a Way Forward: Resilience and Adaptation to Prepare Bakery Students for the Future

Ever since the first humans accidently mixed grains with water to ferment dough, the bakery profession has embraced social, cultural and political disruptions to advance its understanding and practices. During the last five years, the Level 5 Bakery Programme at Toi Ohomai has employed project-based learning (PBL) pedagogies to create real-world learning environments and provide baking students with 21st-century skills. In March 2020, Covid-19 created significant disruptions to this learning environment, with the programme and its learners being forced to quickly pivot their traditional practices to ensure contemporary and pedagogically responsive learning continued. Here, I discuss anecdotal findings around PBL and the work-ready preparedness of bakery students in a post-Covid landscape, with broader implications for PBL environments and responsive pedagogy.

Persepsi siswa terhadap implementasi pembelajaran Bahasa Inggris sebagai Muatan Lokal di Sekolah Dasar

The interaction process that begins with the perception of education actors, namely students and teachers, is one of the factors that influence the success of learning implementation, including learning English. As one of the foreign languages studied in Indonesia, many elementary schools provide English lessons as one of the local contents. This research was conducted to find out the students' perceptions of the implementation of learning English taught in elementary schools. Using descriptive qualitative research methods, this study involved 97 students from nine elementary schools in a municipality in East Java. Data were collected through questionnaires. The data analysis was done by reducing data, presenting data, and drawing conclusions. The results showed that most of the respondents (84.54%) had positive responses regarding learning English at school. There are at least three factors that influence students' interest in learning English, namely students' motivation towards English learning, teacher factors, and fun English learning activities. In addition to studying at school, as many as 63.92% of respondents provide information that they also study English outside of school. This supports learning English in schools to be more effective. On the other hand, the data from the questionnaire also show that students have difficulty in understanding English vocabulary and structure. The results of this study are expected to give recommendations to schools which include teachers and principals to improve the English learning process in order to improve students' English skills for the better and the objectives of learning English to be achieved.

Upaya Meningkatkan Minat Membaca Melalui Metode Sustained Silent Reading pada Siswa Kelas IV SDN 5 Keresek

Reading is one of the most important skills in the language. Before someone has writing skills, they should have reading skills first. However, let alone being skilled, growing interest in reading itself is still quite difficult. Literacy culture cannot be found in most schools in Indonesia, including in SDN 5 Keresek. The application of the SSR (Sustained Silent Reading) method in several studies can overcome the problem of reading. Therefore, this study aims to find out whether the SSR (Sustained Silent Reading) method can increase the reading interest of students of grade IV SDN 5 Keresek. The research approach that is used is qualitative with case study methods. Based on the results of the study, it can be concluded that the SSR (Sustained Silent Reading) method effectively increases the reading interest of students of grade IV SDN 5 Keresek in Garut Regency. This increase is seen gradually in the observation of the first cycle and the second cycle. The increase in reading interest in each of these cycles can occur because sustained silent reading helps encourage students to focus on following reading activities with books that have been handpicked by them. With this method, students are not easily distracted because everyone reads their book quietly and calmly.

SIMADU: Integrated Application to Support Student Activities in University

Electronic-based academic information systems such as websites are needed to support student activities. In its development, the academic and lecture information is stored in a website hosting, in order to make it easier to access the information from anywhere as long as it is connected to the internet. However, according to the Higher Education Database (PDDikti) that the website is constrained when accessed via a mobile device (mobile), due to the large amount of data to be accessed where the specifications of mobile devices are sometimes limited. So it is necessary to develop an application to access academic information based on mobile devices or smartphones. This study uses the ADDIE model method. Based on the results of a survey of Universitas Pendidikan Indonesia students, 43.6% of students were dissatisfied with the website-based academic information system. Students feel ineffective in using too many websites so that it is confusing and troublesome for students to access the information they need. So to simplify the above, it is necessary to conduct research to utilize information and communication technology in supporting the smooth process of distributing academic and lecture information in the form of a tool in the form of an application program called SIMADU.

A multi‐modal fusion YoLo network for traffic detection

Abstract Traffic detection (including lane detection and traffic sign detection) is one of the key technologies to realize driving assistance system and auto drive system. However, most of the existing detection methods are designed based on single‐modal visible light data, when there are dramatic changes in lighting in the scene (such as insufficient lighting in night), it is difficult for these methods to obtain good detection results. In view of multi‐modal data can provide complementary discriminative information, based on the YoLoV5 model, this paper proposes a multi‐modal fusion YoLoV5 network, which consists of three key components: the dual stream feature extraction module, the correlation feature extraction module, and the self‐attention fusion module. Specifically, the dual stream feature extraction module is used to extract the features of each of the two modalities. Secondly, input the features learned from the dual stream feature extraction module into the correlation feature extraction module to learn the features with maximum correlation. Then, the extracted maximum correlation features are used to achieve information exchange between modalities through a self‐attention mechanism, and thus obtain fused features. Finally, the fused features are inputted into the detection layer to obtain the final detection result. Experimental results on different traffic detection tasks can demonstrate the superiority of the proposed method.
