Abstract

Permasalahan gizi buruk pada anak merupakan tantangan kesehatan masyarakat yang memerlukan sistem pemantauan berbasis teknologi untuk penanganan yang lebih efektif. Penelitian ini bertujuan mengembangkan Sistem Informasi Geografis (SIG) berbasis web dengan memanfaatkan Google Maps API guna memvisualisasikan persebaran kasus gizi buruk pada anak secara real-time. Sistem ini dirancang untuk membantu pemangku kepentingan dalam mengidentifikasi daerah rawan, mengoptimalkan alokasi sumber daya, dan merumuskan intervensi yang tepat sasaran. Pengembangan sistem menggunakan metode Waterfall yang mencakup tahapan analisis kebutuhan, perancangan, implementasi, pengujian, dan evaluasi. Hasil pengujian fungsional dengan Black Box Testing menunjukkan seluruh fitur sistem beroperasi dengan baik, sementara User Acceptance Test (UAT) memperoleh tingkat akurasi 95% dalam menampilkan data sebaran kasus. Sistem ini diharapkan dapat menjadi alat bantu yang efektif bagi dinas kesehatan dan puskesmas dalam mempercepat respon penanganan kasus, meningkatkan efisiensi distribusi bantuan gizi, serta mendukung pengambilan keputusan berbasis data spasial yang akurat.

Abstract

Church worship services require a system that can assist in organizing and presenting worship materials in a structured manner so that congregants can follow the service effectively. However, the conventional presentation of liturgy, Bible verses, and songs creates challenges in material management, slide transition flexibility, and limited access for congregants. This study aims to design and implement a web-based liturgical presentation system to improve efficiency and flexibility in managing and delivering worship materials in a single church, namely GMIM Kanaan Likupang Dua. The research employs the Research and Development (R&D) method, which includes requirement analysis, system design using Unified Modeling Language (UML), development, testing, and evaluation. The system is developed using PHP with the Yii Framework 2 and MySQL database, implementing the Model-View-Controller (MVC) architecture. The main features include liturgy management, web-based presentation, a Quick Switch feature for rapid content changes, and QR Code integration that enables congregants to access presentation content through personal devices. Black Box Testing results indicate that all system functions operate properly. Furthermore, User Acceptance Testing (UAT) shows a high level of user acceptance, with 98.75% from multimedia staff and 88.86% from congregants. Therefore, the developed system is considered feasible and effective in supporting more structured, responsive, and inclusive worship services.

Abstract

Digital transformation has opened new opportunities for Micro, Small, and Medium Enterprises (MSMEs) in Manado City to increase market reach and strengthen business competitiveness through online transactions. However, many local MSMEs still have limited access to independent digital platforms, while existing e-commerce systems do not always provide the flexibility needed to handle both physical products and service-based offerings in a localized context. This study aims to design and implement a web-based MSME marketplace for Manado City using the Waterfall software development method. The system was developed with a decoupled architecture consisting of Next.js as the frontend framework, Strapi Headless CMS for backend management, and PostgreSQL as the database. The main features include seller store registration, product and service catalog management, dynamic product variants, map-based location pinning, Live Commerce, Midtrans payment gateway integration, order tracking, and accessibility support. System evaluation was conducted using Black-Box Testing and User Acceptance Testing (UAT) with a five-point Likert scale involving buyer and seller respondents. The Black-Box Testing results show that all tested features functioned as expected. The UAT results produced an average acceptance rate of 89.88% from buyers and 91.38% from sellers. These results indicate that the proposed marketplace is functional, practical, and well accepted by users, making it a suitable digitalization solution for supporting MSMEs in Manado City.
