Abstract

The detection system of DDoS (Distributed Denial-of-Service) attacks aims to enhance network security across all facets of internet technology utilization. One is at SPKLU, which stands for Public Electric Vehicle Charging Station. The research employed a deep learning approach utilizing a Convolutional Neural Network (CNN) on a publicly available dataset. Based on our study and analysis, CNN has a precision rate of 95%. Its high accuracy and balanced performance across diverse attack types indicate the model's practical application in real-life situations. The model demonstrates promising performance in detecting different network traffic anomalies, offering significant insight into its potential for practical use. Further investigation is necessary to strengthen the resilience of DDoS assault tactics against emerging dangers and to tackle any potential constraints.

Abstract

Increasing public health awareness is an important strategic issue to be handled by local governments, especially in the Depok City area. This strategic issue is handled directly by the Depok City Health Service. This is a result of the lack of public health awareness, which is a challenge in health promotion efforts in Depok City. Several technical obstacles were encountered in the field related to limited technical capabilities in using software to create educational and promotional media using technology. This technical ability can be overcome by providing counseling and technical assistance using a selection of simple, smartphone-based tools. This training involved 60 health promoters from community health centers and regional hospitals in Depok City. The pretest results, which illustrate the success of the community service process, stated that 47.2% of health promotion workers rarely received multimedia training, and 17.85% felt that there had never been any multimedia training. Positive responses were given by the participants, as shown by the results of the implementation of 2-dimensional and 3-dimensional multimedia

Abstract

Computer vision’s ability determines the accuracy of object recognition. This study tested the camera's ability to recognize both passive and active markers using LEDs. A specific active marker is analyzed using blinking on the LED. One of the factors to consider when choosing a specific marker is the value of the duty cycle accuracy. The proposed system is confirmed by implementing an integrated control system and the hardware to develop a specific marker. The result shows that the commercial camera can recognize all colors used as the test markers. Here, a specific marker was improved in the bullet launcher system due to tracking, identifying, detecting, marking, locking, and shooting a target precisely. Generally, image processing obtained the comparison of the time to speed the process, the higher the pixel resolution, the longer the time. When the object moves at a certain speed, the camera can detect several marker shapes, such as circles, squares, and triangles. The result shows that a circle marker gives a higher accuracy at every speed level. In the duty cycle variation test, when the duty cycle value is set to 50%, the best accuracy is obtained when the red LED is used, with the accuracy value obtained reaching 96%. In the LED test, it is also found that the effect of light affects the color detection results on the LED. Moreover, using the highest accuracy results from the LEDs at the implementation stage would be very good.

Abstract

The utilization of Virtual Reality (VR) technology for educational purposes, namely in instructing Indonesian culture, particularly the Keris culture, holds significant importance. This is due mainly to the limited dissemination of knowledge on Keris and traditional weaponry inside educational institutions, as they are not currently incorporated into the curriculum. The Universitas Negeri Semarang and Politeknik Negeri Jakarta teams have developed interactive learning media focusing on virtual reality (VR) technology. The primary objective of the virtual reality (VR) application is to provide a comprehensive exploration of Keris culture, intending to foster a deeper understanding and appreciation of Indonesia's rich cultural legacy among the younger generation, mainly elementary school pupils. The approach involves offering instructional sessions to students and educators, focusing on utilizing virtual reality (VR) technology as an educational instrument. Training activities were provided at Barusari 02 Elementary School in South Semarang. Considering technological accessibility is crucial to ensuring that all students can access educational materials without obstacles. The findings derived from administering pre- and post-assessments to primary school children indicate that Virtual Reality Technology has the potential to engender greater interest among pupils in acquainting themselves with Indonesian culture. Most participants, above 80%, expressed a strong positive inclination towards utilizing Virtual Reality (VR) Technology to acquire knowledge about various cultural aspects. By providing appropriate support and adopting a comprehensive approach, virtual reality (VR) has the potential to serve as an efficacious instrument for enhancing students' comprehension and admiration of Indonesian culture.

Abstract

This research aims to evaluate the solar energy characteristics in the Andoonuhu area, Kendari City, Southeast Sulawesi, as a preliminary study for the development of a solar power generation (PLTS). Data collection was conducted using a simulation approach and direct measurements during the period from March to May 2024. The main parameters analyzed include solar radiation intensity, clearness index, zenith, incidence, solar hour angle, and the power output response of the photovoltaic panel SP-50-P36. The study results show that the average daily radiation intensity ranges from 4.5–6.4 kWh/m²/day, with peak energy occurring in May. Analysis of the sun's position on March 23 (equinox) revealed a minimum zenith angle of about 4–5°, indicating near-vertical sunlight conditions relative to the Earth's surface. Solar panels installed at a 15° facing north exhibited relatively small incidence angles during the day, supporting optimal radiation capture performance. Maximum beam radiation was recorded at 12:00 noon, while diffuse radiation contributed more significantly in the morning and evening. The clearness index showed a positive correlation with the solar angle, with optimal values when the elevation angle was above 60°. Panel performance tests revealed a decrease in thermal efficiency due to an increase in module surface temperature up to 49.25°C. This study indicates that the utilization of solar PV energy in Kendari is quite favorable and can be optimized through fixed or tracking system designs. The research provides a technical fundamental data for the development of efficient, sustainable, and adaptive PLTS systems tailored to local radiation characteristics, particularly in the central-eastern region of Indonesia.
