The digital transformation in education has encouraged the adoption of computer-based tests (CBT) using video content, which demands stable and efficient network performance. This study aims to evaluate the performance of two queue management algorithms, namely Random Early Detection (RED) and Per Connection Queue (PCQ), in maintaining the quality of service (QoS) of school networks during online video-based examinations. A case study approach was applied using a real network topology in a school environment, and QoS parameters such as throughput, delay, packet loss, and jitter were measured. The implementation was conducted using a MikroTik RB450Gx4 router configured with simple queue settings for each algorithm. The results show that PCQ provides more consistent performance under high user loads, achieving an average throughput of 56,482 bps and lower delay compared to RED. Conversely, RED performs better in scenarios with a small number of users. The study recommends using PCQ for networks with dynamic and dense user environments, while RED is more suitable for low-traffic conditions where latency stability is crucial. These findings offer practical guidance for managing bandwidth and improving the quality of CBT delivery in educational settings.

Crime and criminality are increasing by utilizing electronic and digital devices, such as CCTV (closed circuit television) security devices, smartphones, and other electronic devices that have video features, record and store perpetrator data. CCTV recording files are sometimes unclear, so video forensic software is needed to clarify the object so that it can be used as evidence in court. The method used in this research is the National Institute of Justice (NIJ) method and enhancement techniques to clarify the image frame objects of CCTV video recordings using Amped Five forensic image and video tools. The results of the analysis of the evidence concluded that they had succeeded in identifying the vehicle number plate of the alleged perpetrator by carrying out an enhancement process (improving the quality) of the image object. The enhancement process is carried out by utilizing the optical debluring feature of the amped five forensic video software, in settings by increasing the size from 1 to 2 and increasing the noise value from 0.0100 to 0.6310 so it looks clearer than before.

In buying a laptop, you need to look at the specifications and standards that are tailored to your needs and requirements. Some of the standards and requirements include looking at several aspects of the criteria including the price of the laptop, RAM (random access memory), processor, hard drive capacity, screen size, VGA (video graphic adapter), battery power, weight, length of warranty, availability of spare parts, service range center. The fuzzy method is a method that makes it easy to find a value that is still vague and also linguistic, the use of the sample additive weighting (SAW) method is used to assist calculations in supporting decision making. The choice of using the SAW method is simpler in calculations, but the results of the calculations are accurate. From the results of calculations using the SAW method, it is calculated that between laptop 1 to laptop 7 with a price preference weight of 30, RAM 10, processor 10, hard disk capacity 10, screen size 5, VGA 3 (video graphic adapter), battery power 7, weight 5 , length of warranty 10, availability of spare parts 5, distance to service center 5, the highest order starts from laptop 1 with a total value of 18.4, laptop 7 with a value of 16.6, laptop 6 with a value of 13.6, laptop 5 with a value of 13.5, laptop 3 with a value of 13.2, laptop 4 with a value of 11.2, laptop 2 with a value of 8.9. The results of the assessment can change according to the needs of laptop buyers, who are more concerned with which criterion has the most important weight.

School promotions were carried out directly by visiting junior high schools, during a pandemic this can’t be done. In an effort to attract prospective new students at SMK PGRI 2 Salatiga, it is necessary to innovate by adding promotional media that can be accessed by the wider community. Information distribution can be done through social media and the school's YouTube channel. Information media was chosen as virtual reality in the form of 360° videos to display school facilities and privileges. The measurement indicators used in this study are behavior, interactivity, and sound to find out whether the virtual environment can affect the interest of prospective students at SMK PGRI 2 Salatiga. In addition, the interactivity of the video when it is played and the sound of the environment in the video can give immersive in a school environment. The results of this study by the majority of respondents stated that promotional media virtual reality in the form of 360° videos is appropriate for use for school promotions during a pandemic, as an effort to increase the number of new students.

Security is an aspect that is needed by all circles today. With security, it can reduce the risk of crime and worry about the crime. This study discusses a room monitoring camera system using a PIR sensor, if a movement occurs it will be detected by this sensor. To process it, NodeMCU is used, then using the Telegram Bot as a notification if a movement occurs. The way this system works is that the PIR sensor will detect the presence of people or not in the room that is given this security system, then NodeMCU will process the data to send notifications in the form of messages and the IP Camera will display live video broadcasts.

Based on the results of observation, the learning method used in SMP Muhammadiyah 3 Kaliwungu is in the form of discourse, discussions, question and answer with the book media. Learning methods that have been applied so far have not had enough impact on students' level of understanding. The method used is less successful, so students feel bored and bored. This study offers a solution for multimedia utilization with the Mind Map method as an interesting learning media, where computers can display text, images, videos and audio so that students can have a pleasant impression in the learning process. The validity value of media experts is 2.9 which is declared feasible, while the validity value of material experts is 3.3, which is declared feasible, and increases students' understanding and interest as users from 58.5% up to 80.5%.

SMK Kyai Ageng Pandanaran Semarang  is one of the private vocational high school that want to improve quality of teaching and learning to produce quality graduates. During these teaching and learning methods that are used less than maximum, students are easily saturated, study time is limited and there are no facilities for new teachers to learn service and auto repair material  efficiently. The authors develop a learning media services and auto repair expert system based that aims to resolve the issue. Learning media is developed by prototype approach. Expert system technology advanced trace method is applied into the learning media through   the facilities of diagnosis and troubleshooting to help new teachers and student learning to identify the damage automobile. Database can be managed and updated by senior teachers by utilizing the MySQL database and PHP programming language. In addition, this learning media also features video demonstration of the *.swf file and the theoretical material in the form of a *.pdf file. The results of the development has produced a new system of web-based expert system as a supplement learning media services and auto repair in the process of teaching and learning activities.
