Several previous studies have shown several approaches in creating a post-flood detection system, including using SMS and using the Web that using the MQTT protocol. However, among the existing detection systems there is not yet a discoverability system to allow users to interact quickly with the system. In this study, a Web of Things-based post-flood detection system was created with the MQTT communication protocol and the Eddystone URL discoverability protocol. Web applications that used on the Web of Things use a Progressive Web App to enable compatibility with mobile devices. The test results show that the use of MQTT in the post flood detection system has a latency of less than 200ms, the use of Eddystone URL as a discoverability protocol in the flood detection system shows a fairly good system response with 90% success in ten trials on the Eddystone URL protocol, and web application testing with Google Lighthouse showed an average score of 91 for mobile web applications and an average value of 96.75 for desktop web applications.</p> Geraldhi Aditya Putra Mahayadnya Gusti Rafi Afkariansyah Franciscus Faust Hartanto Marshelino Laksmana Syahjaya Harianto Harianto Copyright (c) 2021 Antivirus : Jurnal Ilmiah Teknik Informatika 2021-08-09 2021-08-09 15 2 147 162 10.35457/antivirus.v15i2.1611 QUESTION BANK CLASSIFICATION BASED ON BASIC COMPETENCE USING THE WINNOWING ALGORITHM <p>The world of education in Indonesia needs to prepare students to face the increasingly complex challenges of the 21st century. They must be able to think critically, creatively, innovatively and be able to solve problems. In this case, it is necessary to measure student learning outcomes by conducting assessments both in writing and orally. In a written assessment, an educator is expected to have many different question banks so that they can measure the maximum achievement of student competencies. The large number of question banks sometimes makes it difficult for educators / teachers to sort out questions to measure the extent to which students are successful in achieving certain competencies. With the winnowing algorithm, the questions in the question bank are compared with the existing basic competencies using the Jackard Similarity Coefficient to determine which basic competency questions belong to. With this research, it is hoped that it will make it easier for educators to sort out questions in the question bank and make it easier to find out student achievements in certain basic competencies.</p> Azis Suroni Endang Setyati Setyati Copyright (c) 2021 Antivirus : Jurnal Ilmiah Teknik Informatika 2021-10-04 2021-10-04 15 2 163 173 10.35457/antivirus.v15i2.1542 DEVELOPMENT OF ARTICULATE STORYLINE-BASED LEARNING TOOLS WITH ZOOM APPLICATION AS INTERMEDIARY MEDIA IN BASIC GRAPHIC DESIGN SUBJECTS IN THE ERA OF THE COVID-19 PANDEMIC <p><em>The world is suffering by the Covid-19 pandemic which all activities including the learning process is having trouble.

Corn yields are influenced by many factors, among others, the ever-changing climate, water availability, soil fertility, crop management systems and so on. At the time of initial observation to the farmer group failure is often also experienced due to the disruption of pig pests at night. So that a system is needed that can control the handling of pig pests by making traps using a stun tool. To convert DC (Direct Current) current into AC (Alternating Current) can be done with a series of power transistors. The power transistor designed is using the flip-flop method, both transistors will work alternately, this type of change includes a phase changer. The goal in this study was to create a microcontroller-based garden fence control device. This tool is able to provide an alternative in making it easier for farmers to control the land so as to avoid pig pests. The results of the trial DC current changer to AC d field is very well functioning so that farmers no longer experience pig pest disturbances at night.</em></p> Ardiansa Ayu Annisa Akbar Copyright (c) 2021 Antivirus : Jurnal Ilmiah Teknik Informatika 2021-11-18 2021-11-18 15 2 199 208 10.35457/antivirus.v15i2.1721 WEB-BASED GEOGRAPHIC INFORMATION SYSTEM FOR MAPPING LANDSLIDE-PRONE AREAS OF SAMARINDA CITY USING THE SCORE AND WEIGHTING METHOD <p>Landslide disaster occupies the second position of disasters that often occur in Samarinda City after the flood disaster and from this study the results of the level of vulnerability to landslides can be obtained.

One of the systems developed is the Balikpapan City Housing and Settlement Service in charge of carrying out government affairs in the areas of housing, settlements, landscaping and cemeteries. One of the existing fields, namely the housing sector, has a program of providing sanitation assistance and uninhabitable houses to the people of the city of Balikpapan. In its implementation, several obstacles were found, such as the slowness of data on recommendations for aid recipients, ineffective data management, and unclear process transparency. Therefore, a system was created that assists in collecting data on prospective beneficiaries, providing actual and fast progress, as well as a more optimal process of assisting. This SSVS development uses the Personal Extreme Programming method with seven phases, namely Requirements, Planning, Iteration Initialization, Design, Implementation, System Testing, and Retrospective. It is hoped that the existence of SSVS can help the implementation of aid provision more effectively, efficiently, and transparently. This research produces a web-based system with a total of 44 use cases that are carried out in 5 iterations. Testing is carried out by user training to see acceptance from related users. user training is carried out with 3 parties to represent several types of users, from the three parties it shows very good satisfaction and acceptance with a percentage of 100%.</em></p> M.

The systems built are still standalone and not yet integrated, so users must have different accounts on each system. Users must remember each account to access the system and for security reasons users usually change their passwords regularly. This Password change process will take a long time considering that every change made is directly proportional to the number of existing systems. Therefore we need a system that can integrate user accounts and manage the authentication and authorization process. This process requires an additional server that acts as a liaison between the system integrator and the application service system. The purpos of this research is to create an innovative system that can handle all authentication and authorization of each application system and is known as the Single Sign On (SSO) system. So that the benefits of research from the existence of a Single Sign On system, users only by using one user account can access many systems without entering repeated Usernames and passwords. In practice, user account data is retrieved from Cloud Identity via Secure LDAP, then user data is managed by the RADIUS Server and distributed to existing application service systems. The research has been successfully carried out and implemented on a website owned by the Politeknik Negeri Tanah Laut, with the implementation of Single Sign On, login to the website only by using the same Username and password.</em></p> <p><em>&nbsp;</em></p> Fathurrahmani Herpendi Khairul Anwar Hafizd Copyright (c) 2021 Antivirus : Jurnal Ilmiah Teknik Informatika 2021-11-25 2021-11-25 15 2 242 251 10.35457/antivirus.v15i2.1813 SENTIMENT ANALYSIS OF PROGRAM MERDEKA BELAJAR – KAMPUS MERDEKA ON TWITTER USING SUPPORT VECTOR MACHINE <p class="western" lang="en-US" align="justify"><span style="color: #333333;"><span style="font-size: small;"><span lang="id-ID"><em>Merdeka Belajar - Kampus Merdeka Program as one of the public policies by the Ministry of Education, Culture, Research, and Technology, cannot be separated from public opinion.
