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).

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
