Abstract

Abstract The rapid development of technology, including the internet, can trigger data security issues that harm individuals, organizations, or government agencies. One type of attack often used is a Brute Force attack, which falls under the category of cybercrime. The National Institute of Standards and Technology (NIST) often analyzes digital evidence in these cases. This study analyzes Brute Force attacks using NIST methods on a router that is an additional router to the main router. On the network at the Faculty of Engineering, Universitas Muhammadiyah Magelang (UNIMMA), information about the attack and patterns used by the attacker were successfully obtained, including the IP address and time of the attack. It is concluded that the additional router is vulnerable to Brute Force attacks, and firewall settings are necessary to secure it.

Abstract

Kurikulum berbasis kompetensi (KBK) mengubah paradigma dalam mengajar, di antaranya adalah bagaimana mengukur kemampuan siswa yang outputnya adalah kompeten atau tidak kompeten. Hasil pengukuran suatu kompentensi akan berpengaruh untuk kompetensi selanjutnya. Disvarietas siswa dalam suatu kelas, menyebabkan cara dan langkah pencapaian kompetensi untuk setiap siswa berbeda. Namun, dalam suatu rencana perkuliahan hanya ada satu rencana pelaksanaan, yaitu yang tertuang dalam Rencana Pelaksanaan Perkuliahan (RPP). Educational Data Mining (EDM) dengan memanfaatkan clustering, digunakan untuk memetakan kelompok siswa dalam kelas. Hasil penge-lompokan ini digunakan untuk menyusun rencana pelaksanaan perkuliahan yang lebih komperhensif untuk pencapaian kompetensi.

Abstract

Ngipik Hamlet provides various types of population introduction letter services including creating birth certificates, updating family cards due to the addition of new family members, updating family cards due to the death of a family member, updating family cards due to a family member's relocation, issuing new Identity Cards for individuals turning 17 years old, updating Identity Cards due to changes in status, issuing marriage certificates, issuing certificates of insufficient financial capability, issuing business certificates, and issuing death certificates. However, these services are currently manual, resulting in inefficient processing time and the risk of document loss or incomplete documentation during the application process. Therefore, there is a need for a system that can support the application process for population introduction letters. The objective of this research is to develop a Telegram bot utilizing Google Form and Google Spreadsheet. The "Bot Layanan Surat Pengantar Kependudukan Dusun Ngipik" was tested using the black-box method, where each service was tested using dummy resident data and the required documents were inputted according to the specified requirements. The results show the status of the complete file and the evaluation of the file according to the requirements. With the existence of this "Bot Layanan Surat Pengantar Kependudukan", residents can easily submit their introduction letter requests conveniently from anywhere and at any time. This serves as an alternative solution that simplifies the process of requesting population introduction letters for residents.

Abstract

Work from home is a way to reduce the development of the coronavirus termed COVID-19. In the world of education, we have been familiar with e-learning systems where learning is done with any time, any ware, anybody, and anyplace. Nevertheless, the readiness for implementation is not relaxed because there are technical and non-technical obstacles. There are four roles in e-learning wherein the role of instructor and student's role is the core, but the readiness of infrastructure and integration between systems is a problem in itself. The consequence of Work from home is to provide resources independently at home, with cost and geographical challenges. The development of E-learning 3.0, with its U-learning concept, gives a different dimension, especially in the use of cloud service provider applications. In this paper, the E-learning Service Framework is proposed by considering the results of a review of the LearningCube modeling, Interactive Mode Architecture, and Critical Success Factors.

Abstract

Sipropmawa is a web-based system designed to manage, monitor, and oversee the online submission of proposals. However, the use of the Sipropmawa website is still suboptimal and lacks attention to user interface (UI) and user experience (UX) design, especially when accessed through mobile devices, resulting in user discomfort when using the application. Therefore, the motivation behind this testing is to update the UI/UX of the Sipropmawa application from a website to a mobile-based application by implementing the design thinking method. The choice was made to adopt a design thinking approach because it emphasizes creativity in creating new solutions and places a strong emphasis on understanding user needs. This study involves the collection and analysis of data, which includes five stages of the design thinking method: empathize, define, ideate, prototype, and testing. The implementation of the design thinking method in the development of the user interface (UI/UX) yields results that can achieve the goals of the method, which is to enhance user satisfaction and utility. In this regard, the support relies on the results of usability testing, which achieved a final score of 86 and obtained a B classification on the rating scale. Thus, this indicates that users highly appreciate the usability of the Sipropmawa mobile application. The UI/UX design of the Sipropmawa application is expected to serve as a model for future development of the Sipropmawa application.

Abstract

The tourism sector has an important role as a source of income to support regional or national economic growth. Indonesia has a variety of natural beauty, one of which is in Temanggung Regency, Central Java. This diversity also forms the need for clear information about the location and types of tourism available. Therefore, an information system is needed that can help find the best path to the tourist site. One efficient approach is through the Dijkstra algorithm to determine the nearest route. Through the determination of the most efficient route, it will certainly have a positive effect, because it can reduce operational budgets and can optimize better travel periods between destinations. To implement the Dijkstra algorithm on the website using the Rapid Application Development (RAD) Method. In the built system, users can see the nearest route point from the initial location to the intended tourist spot, so it is expected to help users in terms of providing information and finding the shortest route from the point of travel. The result of this study is the application of an information system to determine the shortest route on a distance map using the dijkstra algorithm in Temanggung Regency.
