Tech Cart Press en-US Journal of Information Technology, Software Engineering and Computer Science (ITSECS) 2962-0538 https://www.ejournal.techcart-press.com/index.php/itsecs/article/view/351 <p>Pengelolaan data warga dan iuran bulanan di tingkat Rukun Tetangga (RT) atau Rukun Warga (RW) seringkali masih dilakukan secara konvensional menggunakan pencatatan fisik atau spreadsheet sederhana. Cara ini rentan terhadap risiko kehilangan data, salah rekapitulasi, kurangnya transparansi keuangan, serta keterlambatan informasi bagi warga. Penelitian ini bertujuan untuk merancang dan membangun sebuah aplikasi mobile pengelolaan data dan iuran warga guna meningkatkan efisiensi administrasi dan transparansi finansial. Sistem ini dikembangkan menggunakan metode Waterfall, yang mencakup tahapan analisis kebutuhan, perancangan sistem, implementasi, pengujian, hingga pemeliharaan secara terstruktur. Pengembangan aplikasi memanfaatkan framework Flutter untuk menghasilkan performa multiplatform yang responsif, serta didukung dengan diagram Unified Modeling Language (UML) seperti Use Case, Activity, dan Sequence Diagram dalam pemodelannya. Hasil dari penelitian ini adalah sebuah aplikasi mobile yang berhasil mengintegrasikan manajemen profil warga, pencatatan otomatis tagihan iuran, sistem unggah bukti pembayaran, hingga validasi transaksi oleh pengurus. Berdasarkan pengujian yang dilakukan, aplikasi ini mampu mempercepat proses rekapitulasi data keuangan, meminimalkan kesalahan pencatatan, dan memudahkan warga dalam memantau status iuran secara real-time.</p> Muhammad Hilman Fakhriza Nur Azizah Ali Haidir Indah Suryani Kamrozi Kamrozi Copyright (c) 2026 Muhammad Hilman Fakhriza, Nur Azizah, Ali Haidir, Indah Suryani, Kamrozi Kamrozi https://creativecommons.org/licenses/by-sa/4.0 2026-07-28 2026-07-28 4 3 1 12 10.58602/itsecs.v4i3.351 https://www.ejournal.techcart-press.com/index.php/itsecs/article/view/352 <p>Culinary micro, small, and medium enterprises frequently experience financial instability because conventional deterministic costing methods lack the flexibility to handle daily fluctuations in raw material and overhead expenses. This study develops an adaptive Cost of Production model and generates pricing recommendations using a web-based Fuzzy Mamdani decision support system. The research employs an applied quantitative case study design focusing on a single culinary micro-enterprise operating in a volatile local market. The fuzzy engine processes raw material and overhead uncertainties as linguistic inputs using MIN-MAX inference, while treating direct labor as a constant parameter. Centroid defuzzification calculates the final adaptive cost. The results demonstrate that the conventional deterministic cost was Rp27,077, whereas the Fuzzy Mamdani model adjusted this value to Rp27,532. This 1.68 percent increase functions as a calculated risk premium that protects profit margins against minor supply chain volatilities. The system subsequently generated three margin-based pricing tiers. The standard tier with a 30 percent margin demonstrated a 97.74 percent goodness of fit when compared to actual market prices. The primary contribution is the deployment of a lightweight web artifact that removes the technical barriers associated with desktop-based fuzzy simulations. This tool enables non-technical business owners to transition from heuristic guesswork to transparent, data-driven pricing strategies that inherently buffer against operational cost uncertainty.</p> Fallan Switly Fransisco Parengkuan Chriestie Ellyane Juliet Clara Montolalu Mahardika Inra Takaendengan Copyright (c) 2026 Fallan Switly Fransisco Parengkuan, Chriestie Ellyane Juliet Clara Montolalu, Mahardika Inra Takaendengan https://creativecommons.org/licenses/by-sa/4.0 2026-07-30 2026-07-30 4 3 13 24 10.58602/itsecs.v4i3.352
