An academic information system is a system designed to process educational data. IGracias Mobile is a theoretical information system application that can be used flexibly by Telkom Purwokerto Institute of Technology students. iGracias aims to provide information about lectures to students. iGracias can be downloaded via google playstore. Based on a questionnaire involving students of the Telkom Purwokerto Institute of Technology, they found several problems with the iGracias application so that it could be maximized to provide lecture information to students. Based on the evaluation of the current design using the System Usability Scale (SUS) questionnaire, the contemporary design has a score of 58, which is classified as grade D with a bad adjective rating, so the design needs to be improved. The method used to develop and develop the user interface design on the iGracias Mobile application is the Usability Testing method with a user-centred Design approach. The results obtained from this study are a new design for the iGracias Mobile application, which was made based on the respondents' suggestions and the steps involved in the UCD method. This research found that the new design's usability value has increased from 58 to 80.8, which is included in grade A with an adjective rating of excellent. Then the new design can overcome the problems in the iGracias Mobile application.

The production of water spinach vegetable crops in 2020 in Central Java ranks 2nd in water spinach production, which is 29,108 tons. The amount of water in spinach production and the increased risk of being attacked by pests and diseases will be even more significant, and proper care is needed to improve the quality of water spinach. It takes an expert to convey knowledge about controlling pests and diseases that are good and right. From these problems, we developed a system to overcome the problem of water spinach plant disease. This expert system uses the forward chaining method. The results of this study are a pest and disease diagnosis system on water spinach using a website-based forward chaining method with accuracy testing using the confusion matrix method by testing 50 rules. Of 50 data, 45 are considered appropriate, and the results of 5 rules are not relevant, so the evaluation results of this expert system produce system accuracy with a percentage of 90%.

Human consumption of data and information has become very large due to the enormous growth of data. On the other hand, the increasing need for data visualization in various information media (online or offline) has also become very interesting. Data visualization is not only about beautifying the appearance of data but also about making data more quickly understood and engaging. Tableau specializes in data visualization, data storytelling and dashboards. Training to operate Tableau can answer the needs of pupils, students, the general public, teachers and lecturers as participants. This training aims for participants to apply interactive data visualization quickly and easily using Tableau in dashboard creation activities to explain data in visual form. The methods used in implementing this training are preparation methods and implementation methods as well as training. As a result of this training, 34 participants learned about the importance of data visualization. They learned Tableau as a data visualization tool and visualization training using Tableau to create self-ordered dashboards for examples of COVID-19 cases worldwide.

The North Coast area of Pekalogan City is an area that has great potential for tidal flooding. Some experts say that the geographical condition of Pekalongan City has a high level of vulnerability to global warming. The high value of vulnerability is inseparable from the geomorphological conditions of Pekalongan in the form of sandy beaches and coastal erosion. Due to these conditions, Pekalongan City has become one of the areas affected by the tidal flood. The problem of tidal flooding is not a new problem for Pekalongan City, especially in the North Pekalongan part. In the design of this system will apply the agile `method. In the design of this system will apply the Agile method. In terms of software development guidelines, agile has an understanding that actively and continuously, between developers and customers must always establish good cooperation and communication. This research was conducted using a Geographic Information System (GIS). The integration of Geographic Information System (GIS) technology will provide convenience and advantages in effectively identifying, mapping, and organizing data over a large area. This study aims to make it easier for the people of Pekalongan City to identify areas prone to tidal flooding. This system can open a map of tidal flood-prone areas in Pekalongan City. Based on the results of the questionnaire calculation using a Likert scale, it can be concluded that this system has a good appearance, the layout of this system is easy to understand, this system helps in getting information about the threat of tidal waves in Pekalongan City, and this system is in accordance with what respondents expected because the percentage of index value more than 80% in each question.

Driver fatigue is a critical issue in the logistics industry, contributing significantly to accidents and operational inefficiencies. The system utilizes IoT devices, including physiological and vehicular sensors, to monitor real-time data, such as Heart Rate Variability (HRV), Galvanic Skin Response (GSR), and Acceleration Variance (AV). Blockchain integration ensures secure, immutable data storage and transparency, with smart contracts automating fatigue alerts and management actions. The research results show that HRV increased from 50 ms to 70 ms, reflecting better stress recovery, while AV decreased from 0.85 m/s² to 0.45 m/s², indicating more stable driving behavior. Fatigue alerts dropped by 60%, from 25 to 10 alerts per observation period, demonstrating the system’s effectiveness in early fatigue detection and prevention. The study concludes that the IoT-blockchain integration provides a robust, scalable solution for mitigating fatigue-related risks, enhancing driver safety, and fostering operational efficiency in the logistics sector.

Learning activities for the introduction of various balls are currently still using book media. However, book media has a reading mandate that is still relatively lacking due to the objects displayed in books that are not as real and have less impact on children at an early age. Augmented Reality integrates the virtual world with the natural world built by humans on a computer system. The method chosen in this study is to apply the prototype method. This method was chosen because it has the advantage of realising user needs easier. Testing the functionality of this application is selected by the black box testing method. Using this black box test method, all the functions in the AR Bola application can work as they should. In addition to the black box method, the System Usability Scale (SUS) test method was also carried out. The test results using the SUS questionnaire obtained an average score of 83. This was included in the "Excellent" Adjective Ratings with Grade Scale "B", indicating that the application was good enough for use.

Learning metamorphosis material that is applied to elementary schools is still conventional and not interactive. Metamorphic material requires a clearer picture of the structure of animals and the process of metamorphosis itself. Before the application is distributed to a wider range of customers, it is necessary to evaluate the application in the form of an android-based metamorphosis learning media application. The purpose of this study was to evaluate the usability of the Morphfun augmented reality application using the System Usability Scale (SUS) method. The evaluation was carried out through questionnaires distributed to 10 respondents consisting of 9 students and 1 teacher for grade 6 at SDN Waru Kidul. The results of the evaluation obtained an average score of 72.25 and received a grade C category with the predicate "Good". Referring to the results of the questionnaire statement 4 with a percentage of 50% of users still need assistance when using the application, it is necessary to improve the application features so that users, especially children, more easily understand when using the application without having to use a companion.
