Abstract

The learning process that has been done face-to-face in class has turned into a new habit, which is done online. Education must continue to be carried out considering that Indonesian children are the hope of the nation's future which we must prepare by learning. Information technology is one of the technologies that is growing very rapidly, even during this pandemic. SMA Negeri 1 Tanjungsari is a school located in the South Lampung area and is a superior or advanced school. However, in these schools, the lack of knowledge in the field of information technology can cause obstacles to the learning and teaching process, so it is necessary to be equipped with knowledge in the field of information technology to improve digital literacy skills and learning platforms for students in schools. In connection with the problems that have been described, this service provides a solution by holding a training and creating a learning platform based on e-learning for schools and students based on information technology. This platform was created by the team with the hope of contributing to the school as a learning centre for students. The result of this PkM program is a B-Smart application product as a learning medium for high school students and training is carried out in its operation so that it can be implemented immediately. Digital literacy skills training provides an increase in understanding in the community, seen from the pre and post tests showing an 86% increase in understanding.

Abstract

Security in communication is very important for everyone to pay attention to. To prevent data leakage and illegal retrieval of data, cryptography and steganography can be used. In this study, GOST and XOR LSB with PRNG were used to inject text into images. The final result shows that the combination of these two methods is quite good in terms of image quality, message capacity, embedding speed, and imperceptibility (cannot be seen with the naked eye). Of the 9 image formats tested, 7 images containing messages could be extracted properly with a median MSE of 0.0001935 and a median of PSNR of 85.261. Then, in terms of rotation, all im-age rotations from 90°, 180°, and 270° fail to extract messages and in terms of resizing all sizes from 10%, 30%, 50%, and 80% also fail to extract messages. The average time required for encryption with test data 6 test data is 0.073 seconds with the GOST algorithm, using GOST + XOR LSB with PNRG is 0.485 seconds. By using the XOR combination method LSB with PRNG can store an average of 43.3 bits. From the impercibility test using 5 respondents and visualization using an RGB histogram, it can be seen that there is no difference be-tween the cover image and the stego image.

Abstract

Water desalination is the process of making fresh seawater or the process of making fresh water from salt water. This study uses a thermal desalination process because the salt content produced is less than the results from membrane desalination. This fuzzy method also has several variations in its application. The fuzzy Sugeno method used in this study differs from other methods, that is, with this method the results are in the form of constants or linear equations so that they can automate the desalination process. Tangkil Island is used as the object in this case study because it is a center for family tourism but has difficult access to fresh water. This study tested the results of desalination water by using a salinity measuring instrument with the type of salinity-615 as the standard for reading salt levels. The comparison results have an error value of above 50% due to the difference in the reading digits of the salinity-615 tool, which only has a value of 1 digit behind the comma, so that the results compared with the salt level sensor (embedded), which can read 3 digits behind the comma, have a high error percentage. The results of the tests carried out using Matlab with the actual conditions at the temperature, humidity, and water level observed that the desalination process runs automatically. From the results of these tests, there are very large differences in the calculation of the evaporation rate. The temperature and humidity factors can change at any time, which causes very large differences from the calculation results. In line with the increase in temperature and decrease in humidity, the evaporation process will be faster but will experience a slowdown in the evaporation process if the opposite occurs.

Abstract

Education is an important element that needs special attention, because education is an important element for the progress of a nation. Not only formal education starting from elementary school to high school, it can now be said that higher education has a central role in developing the capabilities of the Indonesian people. One way to get into state universities is with Ujian Tertulis Berbasis Komputer (UTBK). UTBK is set to be the main requirement to take part in the Seleksi Bersama Masuk Perguruan Tinggi Negeri (SBMPTN). Students' abilities cannot necessarily be measured by the UTBK scores. Student achievement when entering tertiary institutions is determined by an assessment of the GPA (Cumulative Achievement Index). In this study the authors tried to find a relationship between the UTBK scores and student GPAs using the linear regression method. The results showed that the correlation between the UTBK and GPA scores was 0.670157 and the mean squared error was 0.0546.

Abstract

Website kuliah atau E-Learning ITERA merupakan sistem yang mewadahi proses belajar mengajar antara dosen dan mahasiswa. Keamanan informasi dari sistem ini sangat penting mengingat banyaknya data terkait nilai ataupun materi perkuliahan yang ada pada website e-learning ITERA. Default password pada e-learning ITERA sendiri sudah ditetapkan. Kredensial pasti juga sudah ditetapkan setiap pengguna yaitu email ITERA. Percobaan ini bertujuan mengetahui celah keamanan menggunakan reverse brute force attack dengan tools OWASP ZAP. Adapun beberapa serangan yang teridentifikasi sebanyak 9 celah keamanan yaitu Cross-Domain JavaScript Source File Inclusion, Incomplete or No Cache-control Header Set, Cookies without SameSite Attribute, Timestamp Disclosure – Unix, Absence of Anti-CSRF Tokens, X-Content-Type-Options Header Missing, Cookies No HttpOnly Flag, SQL Injection, .htaccess Information Leak, Absence of Anti-CSRF Tokens, Cookies No HttpOnly Flag. Hasil pengujian membuktikan bahwa website e-learning ITERA berhasil diserang dengan metode reverse brute force attack dengan pembuktian terdapat 3 URI dengan kerentanan yang beresiko tinggi dengan serangan SQL Injection setelah dipindai menggunakan OWASP ZAP. Hasil mitigasi untuk risiko ini adalah dengan menggunakan query sql dan filter input ke database. Kerentanan Resiko high memerlukan penanganan secepat mungkin karena memiliki resiko yang sangat signifikan kepada sistem. Kerentanan resiko medium juga perlu ditangani secepatnya karena dapat menyebabkan berbagai data yang seharusnya tidak terlihat oleh pengguna dapat diakses. Begitu pula pada kerentanan resiko low perlu ditangani karena dapat memicu celah – celah keamanan lain yang lebih besar, misalnya pada Absence of Anti CSRF Token dapat memicu serangan berupa brute force.

Abstract

Economic growth is one indicator of successful development. An important indicator for knowing the economic conditions in a region in a certain period can be shown by the Gross Regional Domestic Product (GDP) data. An economy is said to experience a change in its development if the level of economic activity is higher than that achieved in the past. Thus, the higher the economic growth, the higher the social welfare. Jambi Province is one of the provinces on Sumatra Island whose economic growth is still below national economic growth, so it is necessary to develop a strategy to overcome this problem. This study uses multiple regression analysis to determine the variables of the people's welfare indicators that influence GRDP in Jambi Province by district/city. From the analysis results, two variables affect the GRDP value in Jambi Province: the percentage of houses with proper sanitation and IPM. It can be concluded, if the Provincial Government of Jambi wants to increase GRDP, then development can be directed at improving proper sanitation services in community housing environments and increasing the IPM of Jambi Province.

Abstract

The development of information technology is currently growing, where now everything has been transformed digitally. Consumers today to shop no longer need to come to the market. Consumers shop through e-commerce applications and just wait for the goods between the couriers from the expedition to arrive at their doorstep. Based on a survey conducted on March 10, 2021, with 100 respondents, it was concluded that 62% of the problems experienced were the process of receiving packages and security risks during package delivery, where the courier did not find the owner of the package at home. Answering the IUI problem requires an IoT-based package receiving box that helps make it easier for couriers to send goods and helps package owners to monitor packages that have been delivered by couriers. This package recipient box is accompanied by an ESP32 Cam camera module to scan the QR code receipt number, ESP8266 helps connectivity and android-based mobile applications with a firebase real-time database to make it easier for package recipients to monitor packages. In helping to facilitate decision making, Mamdani fuzzy logic is used. From the research experiment, it was found that the system can carry out the package storage process with an average time of 11 seconds and the time required to update to firebase is around an average of ±3 seconds.

Abstract

The interface of the automatic answer assessment system is plagued by several issues, including an unfamiliar layout, unresponsive design, inconsistency in elements, and a lack of clarity in presenting information. These problems significantly hinder the overall user experience. As a result, this study aimed to address these challenges by designing a user-centered experience for the automatic answer assessment system, using a high-fidelity prototype tailored to meet user needs. The user-centered design method involved four crucial stages: Specify The Context Of Use, Specify Requirements, Create Designs, and Evaluate Designs. Through rigorous usability testing with teachers, the design achieved an impressive effectiveness rating of 90%, firmly establishing it as a "very effective" solution. Additionally, it demonstrated high efficiency with a value of 0.01307 goals/sec, and teachers expressed positive feedback, confirming the satisfaction and usability of the new interface. Similarly, students' usability testing yielded noteworthy results, with a 90% effectiveness rating, also classified as "very effective." The interface showcased a high level of efficiency, with a value of 0.0849 goals/sec. While the satisfaction value fell below the PSSUQ norm, students still found the interface to be user-friendly and satisfactory. Furthermore, the user experience testing, utilizing the UEQ-S, provided valuable insights. For teachers, the pragmatic aspect scored 1.85, the hedonic aspect scored 2.33, and the overall aspect received a commendable score of 2.09, all of which fell within the excellent category on benchmarks. Similarly, students' ratings were highly positive, with scores of 2.14 for both pragmatic and hedonic aspects, and an overall score of 2.14, signifying an excellent user experience.The retrospective think-aloud validation test reaffirmed the positive response from prospective users. Overall, this research, employing a user-centered design approach, successfully delivered a highly satisfactory and effective user experience for both teachers and students using the automatic answer assessment system.
