Abstract

Penelitian ini berfokus pada investigasi forensik digital untuk menganalisis serangan siber yang terjadi padajaringan, khususnya serangan Denial of Service (DoS) dan brute force, dengan menggunakan alat analisisseperti Wireshark. Tim investigasi dibagi menjadi beberapa kelompok untuk menangani analisis forensikmemori, jaringan, dan penyusunan laporan. Hasil penelitian menunjukkan adanya beberapa serangan DoS,seperti SYN Flood, UDP Flood, dan DNS Amplification, serta bukti satu serangan brute force jenis HybridAttack. Namun, selama investigasi tidak ditemukan indikasi adanya aktivitas malware. Kendala yangdihadapi selama proses investigasi antara lain keterbatasan perangkat dan waktu analisis yangmenyebabkan hambatan dalam penyelidikan lebih mendalam. Penelitian ini menekankan pentingnyapenggunaan alat yang lebih komprehensif dan metodologi yang lebih maju dalam investigasi forensikjaringan untuk memastikan deteksi yang akurat dan lengkap terhadap ancaman siber.Kata Kunci: Forensik Digital, Serangan DoS, Wireshark

Abstract

This study aims to optimize the use of an optocoupler sensor in an Arduino Nano–based ocean current velocity measurement device that is simple, cost-effective, and sufficiently accurate. The measurement system employs a propeller mechanism driven by ocean currents, where the optocoupler sensor detects rotational pulses and the Arduino Nano processes the data to calculate current velocity. The research methodology includes hardware design, software development, and performance evaluation. A comparative testing method was conducted by comparing the measurement results of the developed device with those obtained from a standard ocean current measurement instrument as a reference. Initial test results indicated measurement deviations with an average error of 13.54%, influenced by technical factors such as sensor orientation relative to flow direction, water depth, current turbulence, and data acquisition delay.
