Abstract

Routing Protocol merupakan seperangkat aturan yang digunakan oleh router untuk menentukan jalur dalam meneruskan paket data ke jaringan tujuan. Pemilihan rute penting dilakukan agar paket data dapat sampai ke tujuan dengan tepat. Dynamic routing banyak diterapkan karena menggunakan protocol dan algoritma dalam penentuan rute secara otomatis. Interior gateway protocol (IGP) merupakan salah satu jenis dynamic routing yang digunakan untuk bertukar informasi routing table dalam sistem otonom. IGP terbagi dua kategori: berbasis distance vector dan link state. Tujuan penelitian ini untuk melakukan studi komparasi kinerja routing protocol berbasis distance vector dan link state. Routing Information Protocol (RIP) version 2 atau RIP v2 yang termasuk kategori routing protocol berbasis distance vector dan Open Shortest Path First (OSPF) yang termasuk kategori routing protocol berbasis link state dipilih untuk digunakan dalam percobaab pada penelitian ini. Delay, packet loss, waktu konvergensi, throughput diukur dalam setiap percobaan pada penelitian ini. Berdasarkan hasil percobaan yang telah dilakukan, nilai RTD routing protocol OSPF maupun RIP v2 tidak memiliki perbedaan yang signifikan, tetapi nilai RTT routing protocol RIP v2 0,9 % lebih besar dibanding nilai RTT routing protocol OSPF. Waktu konvergensi ketika terjadi failover, routing protocol OSPF hanya memerlukan waktu sekitar 2,01 s, sedangkan routing protocol RIP v2 memerlukan waktu 178,16 s. Waktu konvergensi ketika terjadi recovery, routing protocol OSPF memerlukan waktu sekitar 49,55 s, sedangkan routing protocol RIP v2 hanya memerlukan waktu 4,04 s. Dalam file transfer, throughput yang dihasilkan routing protocol OSPF sekitar 93 MBps dengan waktu pengunduhan 119,63 s, sedangkan routing protocol RIP v2 sekitar 95 MBps dengan waktu pengunduhan 117,82 s.

Abstract

Current formal education does not only focus on developing scientific and theoretical knowledge, but also pays attention to thought processes and behavior. Extracurricular activities are a means that can be optimized to improve thinking skills or behavior. Of the various kinds of extracurricular activities that exist, robotics is one of the new extracurricular activities, but is very much liked by students. Limited human resources who understand robotics and school support is one of the challenges in introducing robotics technology, especially for elementary school (SD) students. The solution to addressing this problem is that in this community service activity socialization and workshops on assembling robots for elementary school students are carried out. There are three main stages carried out in service activities: initial preparation, implementation, evaluation and reporting. Activities during the implementation of activities, begins with the introduction of robot components to be assembled. Participants in the activity totaling 37 students were divided into 6 groups. Each group was guided to follow the steps of assembling the robot, which consisted of: assembling several robot components and tightening the screws using a screwdriver, uploading the previously made computer program to the chip installed on the robot, activating the robot and controlling it via a smartphone. Partners filled out the questionnaire after the main activities were carried out. Partner responses to 6 statements related to the implementation of community service activities, on average giving a value in the category S = Agree, this means that partners agree and support this community service activity.

Abstract

Proses pencatatan data kehadiran perangkat desa perlu dikelola dengan baik, karena mempengaruhi kinerja pelayanan kepada masyarakat. Pencatatan data kehadiran secara konvensional, biasanya dilakukan saat jam masuk kerja dengan membubuhkan tanda tangan pada sebuah buku atau form daftar hadir. Proses pencatatan seperti ini sangat sederhana dan mudah diimplementasikan, tetapi memiliki kekurangan, diantaranya mudah dimanipulasi dengan cara menitipkan tanda tangan kepada orang lain. Beberapa metode untuk menyelesaikan masalah pada pencatatan data kehadiran konvensional, diantaranya dengan menggunakan alat bantu perangkat elektronik berupa : time recording machine, id card with barcode system, magnetic card dan RFID card. Walaupun sudah menggunakan alat bantu elektronik, tetapi masih terdapat kurangan, karena kartu identitas dapat dititipkan kepada orang lain. Dalam kegiatan pengabdian ini diusulkan untuk menerapkan sistem pencatatan kehadiran menggunakan alat bantu pencatat kehadiran berbasis sidik jari (finger print time attendance). Hasil dari kegiatan PPM ini, telah diterapkannya sistem pencatatan data kehadiran berbasis sidik jari di lokasi mitra pengabdian. Pola sidik jari menjadi alat untuk validasi kehadiran setiap perangkat desa. Laporan data kehadiran secara otomatis diproses oleh sistem, dan dapat ditampilkan atau dicetak ketika dibutuhkan.

Abstract

Documents can now be sent not only in paper form, but also in electronic form, making the distribution process faster. However, documents that require signature validation must be printed and signed conventionally before being sent. This conventional process is time-consuming and cannot be completed if the signer is not present. Balai Sertifikasi Elektronik (BSrE) which is under the auspices of Badan Siber dan Sandi Negara (BSSN) has an information system that implements the digital signature concept. However, this concept is limited to state administration institutions and has a closed source code, preventing it from being developed by the public. The aim of this research is to apply a QR Code-based digital signature system for signing electronic documents. The research method consists of problem identification, system architecture design, implementation, and testing. Based on the results of experiment, digital signatures using cryptographic techniques and QR Codes have been successfully applied in the process of signing electronic documents. Thus, the document signing process can be carried out without printing it first. Each QR-Code successfully embedded in an electronic document as a digital signature can store metadata: date, subject, name of signatory, position, institution or unit. Verification can be performed to ensure that the data stored behind the QR-Code is associated with a document that has been affixed with a digital signature.

Abstract

This study proposes a web-based deepfake detection system that integrates Vision-Based Excitation technology and Transformer-based intelligence, called VERITAS (Vision-based Excitation and Robust Intelligence for Transformer-Assisted Deepfake Detection). The system is designed to automatically detect manipulated images and videos by leveraging the Vision Transformer (ViT) model architecture, equipped with the Grad-CAM mechanism for interpretability of detection results. The study conducted a series of tests to measure the system's performance in various scenarios and ensure its reliability in dealing with various types of input. Load testing results showed that up to 30 simultaneous users, the system can operate with good responsiveness (average response time of 130 ms) without experiencing errors. However, when the number of users reaches 40 or more, the system performance drops drastically with a very high error rate, reflecting limitations in handling server load. Real-world testing showed the system can detect deepfakes with an accuracy of 73.61%, with results varying depending on the quality of the tested images. Furthermore, unit functional testing and coverage analysis demonstrated an excellent test pass rate (85%), with all major functions running smoothly and error handling needed to be fixed in some code sections. Overall, the VERITAS system demonstrates strong potential for web-based deepfake detection, with high reliability under low load and adequate performance in functional testing. However, further optimization is needed to handle higher user loads.
