In this study using 3 clients, the amount of bandwidth used is 10 MBps which is divided into 5 MBps, 3 MBps, and 2MBps assuming the bandwidth will be divided between each client using the HTB (Hierarchical Token Bucket) method. While the Action Research method to be able to determine network performance using QoS parameters, namely Diagnosis (Diagnosing), Action Planning (action planning), Taking Action (Action Taking), Evaluation (Evaluating), Learning (learning). The results of this study are that the delay in bandwidth management using the HTB queuing method is smaller than using the Action Research method, the second throughput in bandwidth management using HTB is smaller than the Action Research method and the browsing speed is faster when implementing the HTB bandwidth management method. While the Action Research Method is only able to evaluate the browsing speed of some network users. Based on the results above, it can be seen that the network quality using the HTB queuing method is more optimal, this is because the bandwidth will be divided according to the rules applied.

Garbage has become a part of life, we all produce waste every day, garbage can also contain many diseases and become a source of disease if left unchecked. So in this study, we will build an Arduino-based smart trash can with an ultrasonic sensor, where if we are less than 25cm away, the trash can will open automatically without us having to hold it. This study aims to reduce direct contact between humans and trash bins and hopes to reduce disease transmission, especially in the SMKN 1 Tirtajaya environment.

SMA Attaqwa 02 Babelan is a high school with its address in Babelan District, Bekasi Regency. In ongoing library activities, it is still carried out in a conventional way, which is still taking notes in books and members come directly to the library to find out information about books. Where this activity is considered to still have problems, including limited library operating hours so that students have to go to the library physically to borrow books. The book stock is limited and the current system is not informative, so that when you come to the library to borrow the book you need, the book has not been returned by the previous borrower. The purpose of this study is to analyze the system that is currently running, in order to overcome the problems faced at Attaqwa 02 Babelan High School, by designing a Library Information System Design at Attaqwa 02 Babelan High School Based on Websites. The research framework that will be carried out in solving the problems discussed is identifying, conducting information searches based on theoretical foundations, collecting data using observation and interview methods, analyzing to find solutions to the problems faced by SMA Attaqwa 02 Babelan.

As motorcycles become more popular in Indonesia, more and more“vocational high schools are offering a core course in motorcycle technique (TSM) in addition to life skills training. They also want their students to become entrepreneurs. This study hopes to provide entrepreneurial opportunities to all his TSM students especially in his SMKN 1 Tirtajaya. This research focuses on motorcycle security based on RFID and Arduino Uno. With motorcycle thefts on the rise at the moment and the high cost of motorcycle security equipment, this study will reduce motorcycle theft crimes and provide entrepreneurial opportunities for students after the completion of SMKN 1 Tirtajaya.”
