Maintaining data that needs to be considered in system security is the authentication process. This process is carried out to ensure users who access data or information on the system are authorized users. There are several methods to authenticate, one of them using data encryption (cryptographic) techniques. Cryptography is applied to data or information by encoding or organizing the data needed only by those who have the key to which the data or information can be accessed. This research will implement the One Time Pad (OTP) algorithm to encode the data and information used. Data or information transferred in the application will form a ciphertext so that users will get a key to access the data or information. The making of this application is expected to guarantee the confidentiality and security of data properly, where the party that can access the original data or information is only the party that has the key.

Social anxiety disorder is a mental health disorder characterized by a fear of being watched, judged, or embarrassed by others. Anyone can actually experience fear or anxiety when interacting with other people. But for sufferers, this fear is experienced excessively and gradually over time. As a result, this condition affects interaction with other people, productivity at work, or achievement at school. For this reason, we need a system that can carry out psychological tests for social anxiety disorder, which are dominated by sufferers with an age range of 10-17 years and even more, sufferers who have anxiety and are afraid to tell what they are experiencing can use this application before deciding to consult a psychologist. . The application of the Dempster Shafer Method in this application provides accurate results on the percentage level of confidence in social anxiety disorder by transferring expert (psychological) knowledge into an Android-based application, the system will be said to be successful if it shows the same or close percentage. Implemented into Android-based software and the application is dynamically displayed and user friendly.

The maze solving robot is the development of the line follower robot. Where the robot can trace a path that has an intersection, in tracing a maze, apart from finding a way out / finish, it will be more efficient if the robot can find a shorter path through the maze. From the maze samples made, the robot can explore a maze and find the shortest path. When the mapping process is carried out, the robot traces 12 path codes; after the path simplification process is carried out, the robot can shorten the path it takes to 6.

Developments in technology and information in the world of website design require students to be able to master the skills needed, especially in designing website layouts. Responsive Web Design is a technique that can make the web-based application design process more dynamic and easy to use on various types of devices. This is because using Responsive Web Design allows the screen resolution, density, and aspect ratio on the website to follow the screen ratio of the device. To make it easier to make a website more attractive and it doesn't take too long, it is necessary to take advantage of the use of HTML which helps regulate the appearance of a website and CSS which helps improve the content to make it more colorful. This Community Service conducts training on making Responsive Web Design using HTML and CSS for students of Tritech Informatics Vocational School in Medan. The method used is in the form of training accompanied by hands-on practice using HTML and CSS on the website layout used. This activity began by conducting a survey on the needs of the training participants to map the needs and expectations obtained from the training participants. Most of the participants stated that the material presented in the training was in accordance with the needs of the participants and 85% of the participants were able to design Responsive Web Design using HTML and CSS. Therefore, similar training activities must be carried out continuously so that students' understanding and skills become more comprehensive and students' confidence in interacting with computer media becomes higher.

The cooperative at the Mahkamah Syar'iyah Banda Aceh faces several challenges, one of which is the limited number of cooperative management personnel involved in developing cooperative business activities. The author identifies two main issues. First, from the perspective of cooperative members, there is difficulty in determining the amount of savings or loans, as the cooperative managers are not always present at the location. Second, from the perspective of the management, the bookkeeping process is still conducted manually. The purpose of this design is to provide easy access to information for members, such as the cooperative profile, savings balance, outstanding loans, and remaining installments. This system also aims to increase the trust of members towards the officers and to facilitate cooperative officers in generating more accurate and efficient reports. From the management side, the system provides access to an admin login page, home, master savings type, master member, savings transaction, loans, repayments, and savings reports. From the member's side, the system allows them to view the amount of their savings and loans. The web-based cooperative information system design at the Mahkamah Syariyah Banda Aceh utilizes fast web technologies for data processing, making reporting more efficient. This system is designed to facilitate data entry, data processing, and data storage, allowing easy access for various purposes such as data retrieval and reporting. The advantages of the Bahagia Bersama Cooperative program include its ability to generate savings reports, loan reports, and member lists.

Post-Traumatic Stress Disorder (PTSD) is a serious mental health condition that can develop after an individual experiences a traumatic event. Early diagnosis of PTSD symptoms is crucial to prevent more severe psychological and social impacts. This study aims to develop a mobile-based expert system application that implements the Dempster-Shafer method to independently diagnose the confidence level of PTSD symptoms. The system is designed with three main components: biodata input, a symptom selection interface based on 9 indicator questions, and an inference engine utilizing the Dempster-Shafer method with a Likert scale to assess the severity of trauma experienced by respondents. Testing was conducted on 47 respondents, and the analysis results showed that 19.1% were in the safe category, 4.3% in mild PTSD, 12.8% in moderate PTSD, and 63.8% in severe PTSD. Validity testing indicated that all symptom items had correlation values (r-calculated) greater than 0.2876, confirming their validity, and the instrument’s reliability was measured at α = 0.806. The application is capable of providing an initial diagnosis along with recommended actions based on the severity level of PTSD. This study demonstrates that applying the Dempster-Shafer method in a mobile application offers an effective, efficient, and accessible alternative solution for early PTSD diagnosis, especially for individuals with limited access to professional mental health services.

Rice is the staple food source for the Indonesian nation. Quality rice is produced from superior rice seeds which have a high yield quantity. At present the agricultural sector is growing with many rice varieties emerging. Superior rice seeds are very important for farmers because rice seeds are the main factor that determine the success of rice cultivation. The existence of many choices makes farmers more careful in choosing the type of rice varieties that suit the soil structure and climatic conditions of the local agricultural environment. The Analytical Hierarchy Process (AHP) method is applied to determine the important criteria for rice varieties and to obtain alternatives that are in accordance with the environmental conditions of agricultural land. The alternatives used are the types of rice seeds in Indonesia, namely Inpari45, Baroma, Jeliteng, Pamelan, and Pamera. This Decision Support System was created to provide information and assist farmers in making decisions regarding the selection of rice seeds to be planted with the criteria of Upright Rice Height, Planting Age, Productive Saplings, and Yield Potential. By applying the AHP method to this Decision Support System, it is found that the best alternative has the highest value of 0.247.
