Abstract

Tripa Multi Mandiri adalah perusahaan yang menyediakan layanan dalam pengurusan sertifikasi industri dan legalitas perusahaan. Untuk meningkatkan kualitas kerja dan memotivasi karyawan, perusahaan ini menerapkan sistem pendukung keputusan untuk menilai kinerja karyawan terbaik. Namun, evaluasi kinerja yang dilakukan secara manual sering kali kurang konsisten dan objektif. Untuk mengatasi masalah ini, penelitian ini mengusulkan penggunaan sistem pendukung keputusan dengan metode Simple Additive Weighting (SAW). Metode SAW, yang dikenal sebagai metode penjumlahan terbobot, mekan penilaian kinerja yang lebih sistematis dan objektif dengan mempertimbangkan lima kriteria utama: kedisiplinan (bobot 0,30), kehadiran (0,20), tanggung jawab (0,20), kerja sama (0,15), dan prestasi (0,15). Data kinerja karyawan dinormalisasi dengan nilai maksimum dan minimum pada setiap kriteria, lalu dihitung untuk mendapatkan skor akhir berdasarkan bobot yang ditetapkan. Hasil evaluasi menunjukkan bahwa metode SAW efektif dalam menentukan karyawan terbaik, dengan nilai total tertinggi mencapai 0,957 untuk karyawan A1 dan nilai terendah 0,787 untuk karyawan A11. Sistem ini memberikan solusi yang lebih adil dan transparan dibandingkan dengan metode manual sebelumnya. Penelitian ini merekomendasikan agar PT. Tripa Multi Mandiri secara berkala meninjau dan memperbarui bobot kriteria penilaian untuk menjaga relevansi dan efektivitas sistem evaluasi.

Abstract

 In the current IS/IT era, service to consumers is an absolute must to be prepared to survive in business competition. Physical and logical attacks with the aim of disrupting information technology services for individuals/agencies/companies or reducing the performance of IS/IT used. The development of IoT in the industrial revolution 4.0, which is all online, is a challenge in itself, from a negative point of view, all of them are able to carry out attacks on ISP servers, often carried out by hackers. DDoS (Distributed Denial of Service) attacks are the most common attacks. The development of software for DDoS attacks is very much on the internet, including UDP Unicorn software to attack very easily and can be done by anyone. Software for real-time monitoring of DDoS attacks, one of which is the Telegram bot. Telegram is a messaging system centered on security and confidentiality, while bots are computer programs that do certain jobs automatically. Telegram bot is free, lightweight and multiplatform. In the case study, this research contains 10 access points to the internet that will be mitigated from DDoS attacks. In this study, it was found that DDoS attacks caused traffic to become very high/congested by fulfilling upload traffic so that legitimate traffic users could not access the internet, connection to the internet was slow, the traffic was also unnatural, making it unable to connect to wireless devices and making Mikrotik  login page becomes unable to appear. The purpose of this study is to mitigate DDoS attacks with the help of telegram bots so as to facilitate the notification of DDoS attacks in the event of an attack so that it is fast to deal with and find the perpetrators of the attack. The conclusion of this study is that DDoS attacks using UDP unicorn software resulted in a traffic spike of 53.5 Mbps on the upload traffic side, causing traffic for legitimate/authenticated users to slow down. By using telegram bots to know DDoS attacks occur in real time with a success rate of attack detection up to 100% notifications on telegram bots. Mitigation of DDoS attacks takes steps to track users using the torch feature on the routerboard interface menu, trace internet connection lines using wired or wireless transmission media, and ensure always monitoring the proxy interface from winbox.
