Abstract

In the current digitalization era, the use of household appliances has been developed using information technology such as the process of using devices using passwords, cards, fingerprints and the like. Likewise, the process of opening doors which is done manually, in the era of digitization can also be developed based on information technology. In this study, a prototype application was developed that could open the door device automatically using a smartphone. The research methodology is carried out by studying literature as a reference for research to be made, observations on software and hardware as well as simulation of hardware and software. The software made in the form of an android application that can detect fingerprints to be able to log into the system and the process of storing usage records with firebase. The hardware uses NodeMCU as a microcontroller board, relay as a current regulator which will be forwarded to the door lock solenoid. The result of the research is an application prototype that can open the door automatically. The process of using the application is done by first logging in using a fingerprint. The application can send commands to open and lock the door automatically. The microcontroller device can realize the command to open and lock the door by activating the solenoid door lock which is set through the NodeMCU and is connected wirelessly via the internet network. Applications can also log all application usage activities. All application usage records are stored in a database. Authority processes in application usage are divided into admin level and user level. At the admin level, admins can view system usage records as well as add, view, modify and delete user data. At the user level, the application is limited to only sending commands in the form of opening and locking doors.

Abstract

Cyber Threat Hunting is one of the activities in the cyber security sphere that is currently developing. Threat Hunting shows the process of proactively searching for vulnerabilities and cybercrime actors through network media to anticipate cybersecurity incidents that will occur in a related infrastructure. Of course with this threat hunting, it will complement passive monitoring activities that only rely on alerts on SIEM (Security Information and Event Management), and the case study that I will raise is the threat hunting method at low level memory so that if there are cybercriminal actors who escape the system SIEM and possibly already on internal systems can be detected and can perform forensic and related system recovery activities

Abstract

Today's communication needs are crucial with the advancement and development of increasingly advanced data communication technologies. To meet your data communication technology needs, you need to be wise when choosing an Internet Service Provider (ISP). You can use more than one Internet Service Provider (ISP) as a solution to meet your Internet requirements. Use load balancing, one of the routing technologies available to use multiple Internet Service Providers (ISPs) at the same time. There are many methods available for load balancing, one of which is the Per Connection Classifier (PCC) method. Per Connection Classifier (PCC) is a method that can be used for load balancing. PerConnectionClassifier (PCC) allows you to group connection traffic through a router into multiple groups. Therefore, the router remembers the gateway path passed at the beginning of the connection traffic, and subsequent packets still associated with the original connection are also forwarded with the same gateway path. The implementation results show that load balancing with the Per Connection Classifier (PCC) method achieves optimal results when using bandwidth from Indihome and Telkomsel Internet Service Providers (ISPs).

Abstract

SMK Muhammadiyah 3 Klaten Utara is one of the private schools whose attendance media still uses an attendance manual or handwriting. By using handwritten attendance media, sometimes the stored data is damaged and easily lost so that attendance recapitulation takes a long time. The lack of communication and information between the school and parents resulted in students being able to report that they were in learning activities but in fact the students were playing with friends. So we need a web-based information system that is connected to a network using an SMS Gateway that can be directly connected to parents to control their children going to school or not. Web-Based Student Attendance Attendance Information System Design at Smk Muhammadiyah 3 Klaten Utara aims to help solve these problems. This information system will be able to manage student data, department data, class data, user data, input attendance data, sms and reports that can recapitulate attendance data. The method in designing this information system uses the waterfall model, using the method of observation and interviews at the time the research was conducted. Applications designed and designed using the Unified Modeling Language (UML), and built using a web-based application using the PHP (Hypertext Preprocessor) programming language, and also equipped with a database designed using MySQL and Modem and Gammu as a tool for sending messages. With this application, you can find out the activities of students who are present at school
