Abstract

The application of the Design Thinking method in the development of a mobile web-based online mail system aims to increase efficiency and convenience in creating, managing, and sending letters digitally. Design Thinking, as an approach that focuses on solving problems by understanding user needs in depth, is used to design more intuitive and user-centric solutions in online correspondence systems. This approach consists of five main stages: empathy, problem definition, ideation, prototyping, and testing, all of which have an important role to play in creating mobile web applications that are accessible, secure, and meet user needs, both in terms of functionality and user experience. In the ideation stage, various concepts and features that can improve efficiency, such as automated mail delivery, cloud-based mail archive management, and electronic notifications and verification, were developed. In the prototyping stage, the design of the interface and basic functions of the application is created which is then tested by involving users to obtain feedback that can improve the system. Testing is carried out on an iterative basis, with a focus on testing functionality and user experience, to ensure that the application can be used effectively and efficiently. The results of the implementation show that this system can increase the speed and ease of digital mail management and provide a better user experience compared to conventional mail systems

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.

Abstract

A web-based Student Organization System (Student organizations) is a platform used to manage activities and information about student organizations in higher education institutions. However, in many cases, many existing systems lack an intuitive user interface (UI) and adequate user experience (UX), which causes difficulties in usage and a lack of user engagement. Therefore, this research aims to design a web-based Student organizations system using the Design Thinking method consists of five main stages: Empathize, Define, Ideate, Prototype, and Test. In this study, the first stage was conducted through interviews and surveys with users to understand their problems and needs. The next stage involved defining the identified issues, followed by brainstorming and generating design ideas that fit the requirements. The developed interface prototype was then tested through user testing to evaluate user experience and system functionality. The results of this study were a user interface design that is simpler, easier to navigate, and meets the specific needs of users. Testing of the prototype showed significant improvements in terms of ease of use and user satisfaction. Thus, the Design Thinking approach has proven to be effective in designing a web-based Student organization’s UI/UX system that better aligns with user expectations. The hypothesis test accepted the application with a user reception rate of 86%. Thus, the system falls into the "very strong" category, who stated that a result percentage between 81% and 100% indicates a very high level of strength in testing. Therefore, the developed system is considered feasible for implementation.

Abstract

Media yang digunakan dalam proses belajar mengajar haruslah memiliki mutu dan kualitas yang baik meskipun media tersebut hanyalah sederhana. Kebanyakan ketika mengajar guru menggunakan LCD yang nantinya akan menayangkan pembelajaran tersebut di LCD biasanya dapat berupa video, Seorang guru ketika mengajar harus memperhatikan berbagai banyak hal, misalnya karakteristik dari setiap siswa, tujuan pembelajaran yang ingin dicapai, metode pembelajaran yang akan digunakan, isi dari materi yang akan dijelaskan, serta strategi pembelajaran yang akan digunakan. Dengan adanya peningkatan kapasistas guru diharapkan Guru memegang kontribusi besar dalam pendidikan karena guru tugas utamabya mendidik, mengajar, membimbing, mengarahkan, melatih, menilai, dan mengevaluasi dan yang berhadapan langsung dengan peserta didik. Serta mengembangkan pembelajaran yang tidak hanya meningkatkan pada aspek pengetahuannya, tetapi dengan aspek spiritual, sosial maupun keterampilannya dan menciptakan desain pembelajaran yang inovatif dan menarik dengan cara yang efektif. Hasil akhir dari pelatihan ini guru dapat meningkatkan kapasistas untuk membuat media pembelajaran yang menarik dan interaktif dengan menggunakan media powerpoint. Dengan media yang berkembang dapat meningkatkan motivasi siswa untuk aktif dan belajar lebih baik.

Abstract

This community service activity aims to improve the efficiency of tilapia pond management through the implementation of a manually operated waterwheel system for the Wildatul Sholihah Activity Group in Bojong Village, Bogor Regency. The partner’s challenges include fluctuating water temperatures, low oxygen levels, and limited manpower, as pond maintenance is only carried out on weekends. As an initial solution, the service team conducted training and installed a simple manually operated waterwheel unit. The activity took place on May 28, 2025, and involved several stages: coordination, module preparation, equipment assembly, technical training, and field testing. The results showed that the waterwheel successfully improved water circulation and temperature stability, while also reducing the frequency of manual water replacement. Training participants demonstrated increased technical understanding, high enthusiasm, and the ability to operate and maintain the device independently. This initiative had a tangible impact in supporting more efficient and sustainable tilapia farming. In the future, the system has the potential to be further developed with the integration of digital technologies such as IoT-based monitoring systems

Abstract

The increasing number of patient visits to hospitals each year poses challenges in providing fast and efficient services, especially during the registration process. Conventional registration systems often cause long queues and patient discomfort. This study aims to design the HealthyQue mobile application as a digital solution for hospital registration based on the Android platform. The application development follows the Design Thinking approach through five stages: empathize, define, ideate, prototype, and test, to deeply explore user needs and behaviors. The results of this process are realized in the form of system modeling using Unified Modeling Language (UML), including use case diagrams, activity diagrams, sequence diagrams, and class diagrams to structurally depict the system's workflow and architecture. This application offers features such as online patient registration, doctor schedule checking, and real-time queue notifications. The implementation of HealthyQue is expected to improve hospital administrative efficiency, reduce patient waiting times, and enhance service quality. The design results demonstrate that the Design Thinking approach effectively produces solutions aligned with user needs, while UML modeling supports the system documentation in a technical and systematic manner.
