Abstract

Kemajuan ilmu pengetahuan dan teknologi pada era modern mendorong lembaga pendidikan untuk menerapkan sistem komputerisasi guna meningkatkan efektivitas operasional. Namun, masih banyak lembaga yang mengalami kendala dalam pengolahan sistem informasi, seperti kesalahan dalam pembuatan laporan, kehilangan dokumen, penyimpanan data yang tidak rapi, serta lambatnya proses pelaporan akibat pencatatan manual. Permasalahan penelitian ini berfokus pada inefisiensi sistem pengolahan informasi pada salah satu akademi futsal. Tujuan penelitian ini adalah untuk merancang dan membangun sistem informasi futsal berbasis web yang dapat meningkatkan akurasi, efisiensi, dan kerapihan dalam pengelolaan data serta pelaporan kegiatan. Subjek penelitian adalah sebuah akademi futsal yang sedang mengalami kendala dalam pengelolaan data secara manual. Metode yang digunakan dalam penelitian ini meliputi observasi langsung terhadap sistem lama, wawancara dengan pihak pengelola, serta dokumentasi kebutuhan sistem. Analisis data dilakukan menggunakan pendekatan sistem berbasis objek, dan pengembangan sistem dilakukan dengan bahasa pemrograman PHP serta database MySQL. Hasil penelitian menunjukkan bahwa sistem informasi futsal berbasis web mampu meminimalkan kesalahan input data, mempercepat proses pembuatan laporan, serta memperbaiki sistem penyimpanan dokumen secara digital. Simpulan dari penelitian ini adalah bahwa penerapan sistem informasi berbasis web memberikan dampak positif terhadap efisiensi manajemen data di lingkungan akademi futsal, serta dapat menjadi solusi atas berbagai kendala yang timbul dalam pengelolaan informasi secara manual.

Abstract

Computer architecture plays a crucial role in the development of embedded systems, particularly in the era of the Internet of Things (IoT), edge computing, and intelligent devices with low battery power. The two main approaches in computer architecture, namely RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing), each have their own advantages and disadvantages in terms of efficiency, speed, and energy consumption. This study aims to compare and analyze the performance of both architectures in the development of modern embedded systems, focusing on several parameters such as instruction efficiency, memory usage, interrupt response time, and support from toolchains and developer ecosystems. This research employs both qualitative and quantitative methods based on a literature review of 20 recent international journals (2020–2025), as well as case studies of implementations on ARM Cortex (RISC), RISC-V, and embedded x86 processors (CISC). The analysis results show that RISC architectures, particularly RISC-V, offer better flexibility, modularity, and energy efficiency, making them well-suited for low-power and real-time applications. However, CISC architectures remain superior in terms of backward compatibility, structured instruction complexity, and broad industry support for traditional applications. The study concludes that the selection of an architecture should consider several factors, including energy efficiency, design complexity, and ecosystem support, according to the specific requirements of the embedded system being developed

Abstract

The New Student Admission (PPDB) process is a critical gateway for educational institutions. However, SMKS Jakarta 1 Pondok Kopi faced a significant 35.4% decline in applicants between 2021 and 2024 due to an inefficient and fragmented PPDB system. Key issues included an outdated information platform, a complex multi-platform registration flow, error-prone manual payment verification, and an insecure online exam system. This research aimed to develop a web-based integrated PPDB information system that consolidates all stages: registration, digital payments via a payment gateway, an online examination with anti-cheating features, and centralized announcements. Using the Waterfall development model, the system was evaluated in two stages. Black Box testing confirmed that all functionalities performed as expected. Furthermore, User Acceptance Testing (UAT) revealed a very high acceptance rate, achieving average scores of 4.48 out of 5.00 from student proxies and 4.50 from the committee, yielding a final interpretation of “Very Good.” The practical implication of this system is a significant improvement in administrative efficiency, data accuracy, and modernization of the school's services. This research contributes by providing and validating an effective integrated PPDB system model, proving it to be a comprehensive solution for vocational education institutions.

Abstract

The rapid development of information and communication technology has significantly influenced various sectors, including the trade industry. One sector experiencing notable growth is the fashion industry. The increasing use of the internet and digital devices has changed consumer behavior, with many people preferring online shopping for its convenience, efficiency, and accessibility. This trend has encouraged fashion businesses to adopt digital platforms such as e-commerce websites to expand their market reach and improve customer service. This study aims to design and develop a fashion e-commerce website that facilitates online buying and selling transactions. The system is expected to help fashion business owners promote and market their products more effectively while providing consumers with greater convenience in accessing product information and completing purchases. The system's development process uses the waterfall method, comprising the following stages: requirements analysis, system design, implementation, testing, and deployment. This method is chosen because it provides a structured and systematic approach to software development. The results of this study indicate that the fashion e-commerce website was successfully developed, featuring a product catalog, shopping cart, payment system, and order management. System testing was conducted using the black-box testing method, demonstrating that all features function properly in accordance with the specified system requirements. Therefore, the developed website can support digital marketing and enhance the online shopping experience for consumers.
