Abstract

Traffic lights are lights that are used to regulate the smooth flow of traffic at a road intersection. The traffic light system in the city of Bengkulu currently still uses a time system that is already installed in the system and does not have a feature for setting the switching time. This system means that operators cannot change the flashing time of traffic lights to suit road conditions and vehicle density at each intersection. In this research, an IoT-based traffic light control system is developed so that it can be controlled centrally using Arduino Mega, Arduino Uno, ENC28J60 as a traffic light machine and using a web-based application as a centralized control system. The research method used is the prototype method, where by using this method there are several processes that must be carried out, including analysis, planning, building a prototype, evaluating initial use, improving the prototype, and implementing and maintaining. The results of this research are that traffic lights can be controlled centrally using a web-based application, where the response time from the Arduino Mega only takes a matter of seconds. From tests carried out on one of the buttons, a response time of 1010.4 ms (milliseconds). Apart from that, the system being built can also display status messages when selecting the status button on the web page based on the selected intersection, then the web application will display information on the intersection status, intersection mode and intersection location.

Abstract

Penelitian ini bertujuan untuk menganalisis dan mengimplementasikan keamanan jaringan berbasis Firewall Raw terhadap serangan Distributed Denial of Service (DDoS) pada Router Mikrotik. DDoS merupakan ancaman serius yang dapat mengganggu layanan jaringan, sehingga penting untuk menguji efektivitas Firewall Raw dalam menghadapi serangan tersebut. Dalam penelitian ini, pengujian dilakukan dengan tiga jenis serangan DDoS, yaitu TCP SYN Flood, UDP Flood, dan ICMP Flood, pada jaringan lokal dan jaringan internet. Metode penelitian yang digunakan adalah metode eksperimental, di mana konfigurasi Firewall Raw disesuaikan untuk berbagai protokol yang diuji. Hasil penelitian menunjukkan firewall raw mampu memblokir lebih dari 70% paket serangan DDoS. Dari sisi performansi sebelum firewall raw diaktifkan, penggunaan CPU pada router sebesar 100% dan free memory 5.8 MiB saat serangan terjadi. Ketika Firewall Raw diaktifkan, CPU menurun menjadi 60-70% dan free memory meningkat menjadi 9.8 MiB. Pada pengujian DDoS lewat jaringan internet juga menunjukkan penurunan CPU Load dari 100% turun menjadi 5% dan free memory dari 4.5 MiB meningkat menjadi 8.0 MiB. Pengukuran Quality of Service, menunjukkan tidak terlihat peningkatan yang signifikan saat Firewall Raw diaktifkan. Penelitian ini menyimpulkan bahwa Firewall Raw cukup efektif dalam memblokir sebagian besar paket dari serangan DDoS. Namun, belum mampu meningkatkan stabilitas jaringan karena jaringan masih mengalami penurunan saat Firewall Raw aktif.

Abstract

The development of Internet of Things (IoT) technology has had a significant impact in various fields, including the fisheries sector. In fish farming, water quality and feeding efficiency are important factors that affect fish health and growth. This study aims to design and implement IoT-based automatic fish feed and water turbidity monitoring system. This system uses an ESP32 microcontroller connected to a turbidity sensor to monitor water turbidity levels, an ultrasonic sensor to detect feed levels, and actuator devices in the form of servos and water pumps. Turbidity data and device status are transmitted in real-time via MQTT protocol to web-based monitoring application and an Android app. Test results indicate that the system can accurately monitor water turbidity levels and activate feeding according to a schedule or manually via the user interface. The testing was conducted in a 40x12x15 cm aquarium containing five guppy ornamental fish, and on the seventh day, an increase of 1 NTU was recorded. The implementation of this technology is expected to improve operational efficiency, reduce feed waste, and maintain aquarium environmental quality sustainably..

Abstract: This community service activity aims to improve the knowledge and skills of students at SMA Negeri 03 Bengkulu Utara in utilizing information technology for online business. Before the training, a pretest was conducted to measure the participants' initial knowledge, which showed that most participants had a low basic understanding before the training, with only 30% of participants successfully answering with a score of more than 60% of the total questions correctly. However, after the implementation of the training program, the posttest results showed a significant increase, where the average score of participants increased to 57% successfully answering with a score above 70% and 43% of participants successfully answering with a score of more than 80%. Feedback from participants showed that they felt more confident in applying this new knowledge in their business practices. Thus, this program provides direct benefits to students and contributes to the development of skills that are relevant to market needs in the digital era. It is hoped that similar activities can be continued in the future with more in-depth and diverse materials, as well as post-training mentoring support. Through a systematic and participatory approach, this program is expected to continue to support the development of student competencies in the fields of information technology and entrepreneurship, as well as provide a positive impact on society as a whole. Keyword: Information Technology, Online Business, Digital Products.  Abstrak: Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan siswa di SMA Negeri 03 Bengkulu Utara dalam pemanfaatan teknologi informasi untuk bisnis online. Sebelum pelatihan, dilakukan pretest untuk mengukur pengetahuan awal peserta, yang menunjukkan bahwa sebagian besar peserta memiliki pemahaman dasar yang rendah sebelum pelatihan, dengan Hanya 30% peserta yang berhasil menjawab dengan skor lebih dari 60% dari total pertanyaan dengan benar. Namun, setelah pelaksanaan program pelatihan, hasil posttest menunjukkan peningkatan yang signifikan, di mana rata-rata skor peserta meningkat menjadi 57% berhasil menjawab dengan skor diatas 70% dan 43% peserta berhasil menjawab dengan skor lebih dari 80%. Umpan balik dari peserta menunjukkan bahwa mereka merasa lebih percaya diri untuk menerapkan pengetahuan baru ini dalam praktik bisnis mereka. Dengan demikian, program ini memberikan manfaat langsung bagi siswa dan berkontribusi pada pengembangan keterampilan yang relevan dengan kebutuhan pasar di era digital. Diharapkan kegiatan serupa dapat dilanjutkan di masa depan dengan materi yang lebih mendalam dan beragam, serta dukungan pendampingan pasca pelatihan. Melalui pendekatan yang sistematis dan partisipatif, program ini diharapkan dapat terus mendukung pengembangan kompetensi siswa di bidang teknologi informasi dan kewirausahaan, serta memberikan dampak positif bagi masyarakat secara keseluruhan. Kata kunci: Teknologi Informasi, Bisnis Online, Produk Digital.

Abstract

The need for an efficient electrical energy consumption monitoring system is increasingly urgent in the digital era, especially to overcome power wastage due to the large number of electronic devices used. This research aims to develop a web application. The method used in this research is the experimental method with a system engineering approach, through the user interface. The application was built using PHP, HTML, CSS, and MySQL, and integrated in the XAMPP environment. The test results show that the application is able to display energy data interactively, both in graphical and tabular form, and provide reports in PDF and Excel formats. The system also provides the feature of controlling devices such as lights and fans through the dashboard, thus increasing efficiency and user convenience in managing energy consumption. With its comprehensive features and user-friendly interface, this application is expected to be an effective solution in supporting energy savings.
