Abstract

Digital forensic investigation is a crucial process in collecting, analyzing, and presenting digital evidence that can be used in law enforcement. One type of storage media that is often used as an object of investigation is optical drives, such as CDs, DVDs, and Blu-rays. This study discusses the application of the National Institute of Standards and Technology (NIST) standard method in the forensic analysis of optical drives. The methodology used includes the stages of identification, acquisition, analysis, and reporting, all of which are in accordance with NIST guidelines. Through the application of the NIST method, this study highlights the reliability and accuracy of the procedure in ensuring the integrity of digital evidence from optical drives. This study also discusses challenges that are often faced in the forensic process, such as physical damage to the media and data encryption. The results of the study show that a systematic approach based on NIST standards can improve the accuracy and validity of the investigation results. Thus, the application of this standard is very important to support the credibility of digital evidence in court. Investigasi forensik digital merupakan proses krusial dalam pengumpulan, analisis, dan penyajian bukti digital yang dapat digunakan dalam penegakan hukum. Salah satu jenis media penyimpanan yang sering dijadikan objek investigasi adalah optical drive, seperti CD, DVD, dan Blu-ray. Penelitian ini membahas penerapan metode standar National Institute of Standards and Technology (NIST) dalam analisis forensik optical drive. Metodologi yang digunakan mencakup tahapan identifikasi, akuisisi, analisis, dan pelaporan, yang semuanya sesuai dengan pedoman NIST. Melalui penerapan metode NIST, penelitian ini menyoroti keandalan dan ketepatan prosedur dalam memastikan integritas bukti digital dari optical drive. Studi ini juga membahas tantangan yang sering dihadapi dalam proses forensik, seperti kerusakan fisik media dan enkripsi data. Hasil penelitian menunjukkan bahwa pendekatan sistematis berdasarkan standar NIST mampu meningkatkan akurasi dan validitas hasil investigasi. Dengan demikian, penerapan standar ini sangat penting untuk mendukung kredibilitas bukti digital di pengadilan.

Abstract

Dalam era digital yang terus berkembang, kebutuhan akan sistem informasi menjadi hal krusial dalam menunjang kegiatan administrasi dan operasional di berbagai instansi. PT. PLN (Persero) UP3 Sidoarjo selain bergerak di bidang jasa kelistrikan juga memberikan kesempatan para pelajar untuk merasakan seperti apa dunia kerja sebenarnya melalui kesempatan magang yang diberikan oleh perusahaan. Dalam pelaksanaan pendataan peserta magang selama ini pengelolaan dilakukan secara manual sehingga memunculkan berbagai kendala seperti duplikasi data, keterlambatan pencetakan sertifikat, dan kesulitan dalam pemantauan jumlah peserta magang yang aktif. Permasalahan ini mendorong dilakukannya penelitian untuk merancang dan membangun sistem informasi manajemen peserta magang yang mampu memfasilitasi proses pendataan peserta magang. Penelitian ini menggunakan metode Software Development Life Cycle (SDLC) model Waterfall, yang meliputi empat tahap utama: analisis, desain, pengkodean, pengujian sistem menggunakan metode black-box. Dalam rancang bangun yang telah dilakukan berhasil menghasilkan sebuah sistem yang dapat memenuhi seluruh kebutuhan pengguna.

Abstract

The need for a stable and high-performance network is essential to support real-time data transmission. One common challenge faced is the effective management of two or more internet connections to avoid bottlenecks on a single link. This study aims to optimize network performance by implementing the Load Balancing PCC (Per Connection Classifier) method on Mikrotik routers to evenly distribute traffic load across two available ISP links. The research methodology used is PPDIOO (Prepare, Plan, Design, Implement, Operate, Optimize), an approach that encompasses all network management activities. The testing environment is simulated using PNETLab, with performance monitoring conducted using tools such as Zabbix Server Monitoring and Speedtest.net. The parameters tested include Quality of Services such as throughput, response time, bandwidth utilization, and traffic load distribution across each ISP link. The test results show that the application of the PCC method significantly improves network performance. The average throughput increased from 1.49 Mbps to 2.08 Mbps, response time decreased from 3.6 ms to 1.6 ms, and download bandwidth utilization increased from 0.43 Mbps to 0.96 Mbps. Furthermore, the traffic load, which was initially concentrated on a single ISP link, was successfully distributed evenly across both links, demonstrating that PCC load balancing is effective in balancing connections. Therefore, this method is highly recommended for network implementations that require high efficiency and stability in traffic management.
