Abstract

This research aims to design an information system for buying and selling motorbike units using the Waterfall method. The information system for buying and selling motorbike units has an important role in supporting motorbike sales business activities, from ordering to the payment process. The design of this system was carried out by following the Waterfall method approach which consists of several stages, namely requirements analysis, system design, implementation, testing and maintenance. The needs analysis stage involves identifying business and system user needs, including required functions and system requirements. Next, system design is carried out by designing the structure, interface and transaction process flow using the notation and methods provided by the Waterfall method. In implementation, an information system for buying and selling motorbike units is developed based on the design that has been created. Then, testing is carried out to verify the success of the system in carrying out its functions and ensure conformity with the specified needs. After that, the system is ready for use and maintenance is carried out to maintain the performance and reliability of the system on an ongoing basis. By applying the Waterfall method in designing a motor unit buying and selling transaction information system, it is hoped that it can produce a system that is structured, has functions that suit business needs, and is tested overall. The Waterfall method also allows developers to have a clear understanding of each design stage before moving on to the next, thereby minimizing the risk of errors and deficiencies in the system.

Abstract

Some motorbike service workshops generally do not use information technology, so there are several obstacles found in their business processes. Where the process of recording service data takes quite a long time because the data is still written manually using books, so there is still a lot of data that is still not neatly arranged. When inputting service data there are often errors, so that the service data is no longer accurate. Then checking, updating and searching for spare parts stock takes a long time, because there are no reports of spare parts stock that will run out or have already run out. So if there are consumers who need spare parts, it is often these consumers. The wait was quite long because the company checked manually by checking directly at the warehouse. The Unified Modeling Language design model can make it easier for system developers to design the system that will be created because of its object-oriented nature. This Motorcycle Dealer Service Management Information System can make it easier for workshop admins to process motorbike service data in Motorcycle Workshops. By using this Motorcycle Dealer Service Management Information System, you can save time and simplify admin performance in carrying out motorbike servicing and creating service transaction reports.

Abstract

Serangan siber berbasis pemindaian jaringan dan eksploitasi sistem menjadi ancaman signifikan bagi keamanan aplikasi web. Alat seperti Nmap dan Metasploit banyak digunakan oleh peretas untuk mengidentifikasi celah keamanan serta mengeksploitasi sistem target. Penelitian ini bertujuan untuk mengevaluasi efektivitas layanan Cloudflare dalam memitigasi serangan reconnaissance dan eksploitasi tersebut. Metode yang digunakan adalah pendekatan eksperimental dengan melakukan simulasi serangan terhadap dua lingkungan server: satu tanpa proteksi Cloudflare dan satu dengan konfigurasi penuh layanan Cloudflare. Serangan dilakukan menggunakan teknik pemindaian port dan service enumeration dari Nmap, serta injeksi payload eksploitasi menggunakan Metasploit Framework. Hasil pengujian menunjukkan bahwa Cloudflare mampu secara signifikan mengurangi keberhasilan pemindaian dan eksploitasi, dengan tingkat deteksi dan pemblokiran mencapai lebih dari 90% terhadap permintaan mencurigakan. Fitur seperti Web Application Firewall (WAF), rate limiting, dan penyembunyian IP server terbukti efektif dalam menghambat proses pengintaian serta serangan berbasis payload otomatis. Penelitian ini menyimpulkan bahwa Cloudflare merupakan solusi mitigasi yang efisien dalam meningkatkan ketahanan sistem web terhadap serangan berbasis Nmap dan Metasploit.
