Abstract

The Covid-19 has become a epidemic that is troubling the public because of the extent and speed of the virus spreading. The Covid-19 has resulted in people being unable to move outside their homes freely so that household consumption has decreased. This condition is similar to the crisis in 1997-1998, where MSMEs and small traders could survive. In Banyumas district, the percentage of MSMEs are in the large, medium, and small groups that can support the habit of Mega Shifting, or businesses that can be done at home so that they can be an economic savior in the covid-19. Clustering is a method of grouping similar objects which are taken from several criteria. X-Means is a grouping method that can be used to effectively calculate the value of K. As for testing the quality of a cluster using the Purity test method, it is said to be "Good" if the results of this Purity are close to 1. The total of MSMEs in the Banyumas district which be grouped is 27,574 MSMEs. The purity based on the results of the cluster is 0.9892 (3 groups), 0.9894 (4 groups), 0.9928 (5 groups), and 0.9677 (6 groups). In 3 groups, the results of grouping are 58 MSMEs belong to large groups, 381 MSMEs belong to medium groups, and 26,602 MSMEs belong to small groups. The recommended MSMEs sectors to face mega shifting are food stalls, culinary, agriculture, snacks, traders, craftsmen, workshops, furniture, constructions, and grocery stores.

Abstract

Special School B (SLB B) Yakut Purwokerto is an extraordinary school that focuses on handling Deaf Children with Special Needs (ABK) under the auspices of the Tama Business Welfare Foundation (YAKUT). In the process of monitoring student progress for guardians, SLB B Yakut Purwokerto still uses manuals and serves individual guardians. This is of course very ineffective and efficient. In addition, teachers also use social media in the form of WhatsApp to contact students' parents when students have finished learning activities at school. The development of technology is currently very rapid and it is appropriate for SLB B Yakut Purwokerto to develop monitoring activities using an effective and efficient system. Based on a review of several previous studies, User Centered Design (UCD) is an effective and most frequently used method to build an application. In understanding the user's cognition, character, and attitude, the design of the monitoring application for SLB B YAKUT Purwokerto students must focus on the user by applying the User Centered Design (UCD) method so that the application seems more interactive. The collection of user needs is carried out using three ways, including observation, interviews, and collecting the required documents. There are 5 stages that must be passed to implement the UCD method, plan the human-centered process, specifically the context of use, specify user and organizational requirements, product design solutions, and evaluate design against user requirements. The result of this research is that the design of the SoBat Yakut Monitoring System application design has been successfully completed to the prototype stage.

Abstract

During the pandemic, the learning model directly impacts both students and teachers, especially in evaluating and correcting assignments to measure student learning. Evaluation and correction of the learning process at both the high school and high school and university levels are generally carried out multiple-choice examinations during this pandemic. Many tools can be used to carry out multiple-choice assessments. The essay assessment is usually done manually and takes a long time because the lecturer has to make corrections one by one. On the other hand, information retrieval is a concept that can be used to build an automatic essay correction information system so that the correction of essay questions can be done quickly and efficiently, as in multiple-choice works. The automatic essay correction information system is a relatively new technology, especially for its plural use in this pandemic. A new technology that will be applied in a plural manner requires a measurement. One of the measurements that can be used is the Technology Readiness Index (TRI). TRI is used because it can measure the readiness and tendency of users to implement an information system. The case study in this research was conducted at the Faculty of Informatics (FIF) Telkom Institute of Technology Purwokerto (ITTP). The TRI measurement of the automatic essay correction information system carried out at FIF produces a TRI of 3.27. This value is between 2.90 and 3.51 (2.90 ≤ TRI ≤ 3.51). Consisted of an optimism value of 1.01, and innovativeness value of 0.52, a discomfort value of 0.55, and an insecurity value of 1.19.

Abstract

Internet services have the potential to be targeted by hackers using various DDoS (Distributed Denial of Service) attack techniques, including the ping of death attack. This attack involves multiple machines launching simultaneous attacks on the database server and File Transfer Protocol (FTP), resulting in severe consequences for computer networks. To effectively classify such attacks, the Fuzzy Tsukamoto method is employed, which represents each IF-THEN rule as a Fuzzy set with a corresponding membership function. Fuzzy logic offers great flexibility, tolerance for imprecise data, and the ability to model highly complex and nonlinear functions. By implementing this classification technique, it becomes easier to differentiate and analyze network traffic captured by Wireshark, enabling the detection of ping of death attacks against the server with maximum accuracy through the Fuzzy Tsukamoto method in the classification process.
