Abstract

The design of a Project Management Information System (PMIS) using the Program Evaluation and Review Technique (PERT) method at PT Media Jaya Konstruksi aims to optimize project scheduling planning and control. PERT was chosen because it can analyze uncertainties in project task completion time by estimating optimistic, pessimistic, and most likely durations. The system is designed to facilitate the company in managing the complexities of construction projects, estimating project duration, and identifying critical paths that impact project success. The system development methodology follows the PERT approach, encompassing the stages of requirements analysis, design, implementation, testing, and maintenance. Key features of the system include creating PERT diagrams, calculating critical paths, simulating project schedules, and generating automatic reports. Additionally, the system is equipped with an interactive dashboard to visualize project progress and support data-driven decision-making. The design results show that the PERT-based information system can help PT Media Jaya Konstruksi identify project bottlenecks earlier, reduce the risk of delays, and enhance project management efficiency. The system's implementation is expected to support the company in increasing competitiveness and maintaining client satisfaction through more structured and timely project completion.

Abstract

This study aims to design and develop a web-based village administrative service information system for the Ulak Kemang Baru Village Office. The system is designed as a solution to various issues faced in manual administrative services, such as slow document processing, inefficiencies in document management, and limited time and accessibility for the community. Through the web-based system, the community can submit administrative requests online, while village officials can manage data in a more structured and efficient manner. The software development method used is the Prototype method, which enables iterative system development involving user feedback. The system design process utilizes Unified Modeling Language (UML) for system modeling, while system implementation is carried out using PHP and MySQL. The system testing was performed using the blackbox method, which focuses on testing system functionality without considering internal implementation details. The results indicate that the information system can improve the efficiency and effectiveness of village administrative services. The system successfully provides key features such as user registration, document submission, verification by village officials, and report generation. Based on the testing results, all major system features function as expected according to user requirements. With this system, it is expected that administrative services at the Ulak Kemang Baru Village Office will become faster, more transparent, and easily accessible to the community, supporting the digitalization of public services at the village level.

Abstract

This research aims to design and develop a Web-Based Construction Project Management Information System for PT Jaya Kusuma to address various challenges, such as manual project submissions, budget planning (RAB) calculations using Microsoft Excel, and inefficient project progress reporting. The system is designed using the Agile Development methodology to ensure flexibility and responsiveness to user needs. Key features include online project submission, automated RAB management, uploading of initial agreement and contract documents in PDF format, and real-time project progress monitoring, all of which are accessible to clients, managers, and supervisors. Additionally, the system provides graph-based reports, enabling directors to monitor project performance easily. The implementation results indicate that the system enhances business process efficiency, data transparency, and service quality for clients while reducing the risk of errors in construction project management.

Abstract

The advancement of information technology has created significant opportunities to enhance efficiency and modernization, including in the Micro, Small, and Medium Enterprises (MSME) sector. MusiCraft, an MSME in Palembang, is engaged in woven crafts and food products, but faces various operational challenges, including manual sales methods, traditional transaction recording, and limited product promotion. This study aims to design and develop a web-based sales information system to address these challenges. Through this system, customers can easily access product information, make purchases, and utilize modern payment methods. For business operators, the system offers features for stock management, automatic transaction recording, and a customer loyalty program that rewards customers. The research employs the Research and Development (R&D) method with a prototype approach, involving users to ensure the system meets their needs. The study results indicate that the web-based information system enhances operational efficiency, expands market reach, and strengthens MusiCraft’s competitiveness in the digital era. The implementation of this system is expected to support MSME sustainability and provide a better shopping experience for customers.

Abstract

Forecasting adalah suatu proses analisis untuk memprediksi nilai-nilai masa depan berdasarkan informasi data historis, atau tren yang telah ada. Forecasting melibatkan metode matematika, statistik, untuk menghasilkan perkiraan tentang apa yang mungkin terjadi di masa mendatang dengan mengumpulkan data historis jumlah mahasiswa baru yang mendaftar selama 11 tahun terakhir. Data harus mencakup periode waktu yang cukup lama untuk mengidentifikasi tren dan pola, kemudian analisis data historis untuk mengidentifikasi tren, musiman, atau fluktuasi lainnya. Analisis data dilakukan dengan menggunakan teknik analisis single exponential smooting akan memperhitungkan nilai alpha (konstanta smoothing) untuk menghasilkan perkiraan yang paling akurat. Analisis data menggunakan tiga nilai konstanta alpha 0.3, 0.6, 0.9 tersebut akan dipilih nilai alpha dengan nilai error terkecil, dan kemudian akan di aplikasikan pada sistem peramalan berbasis website. Melalui sistem berbasis website, informasi dapat dikelola secara efisien dan memungkinkan Universitas Indo Global Mandiri untuk mengoptimalkan proses penerimaan mahasiswa baru mereka. Dengan menerapkan metode peramalan ini dalam sistem berbasis website, Universitas Indo Global Mandiri dapat mengelola informasi secara efisien, yang pada gilirannya akan membantu mereka mengoptimalkan proses penerimaan mahasiswa baru. Analisis data dengan tingkat error terkecil, dapat diartikan bahwa metode peramalan tersebut telah memberikan hasil yang sangat mendekati dengan data aktual, sehingga dapat diandalkan untuk melakukan proyeksi ke depan.
