Perancangan Dan Implementasi Aplikasi Manajemen Data Tagihan Air Menggunakan Metode Pieces Berbasis Web (Studi Kasus: Ksm Tirta Lestari Flamboyan)
This study is motivated by the need for effective and efficient clean water management at KSM Tirta Lestari Flamboyan. Currently, water usage recording and billing are still conducted manually, including field data collection, spreadsheet-based recapitulation, and manual creation of payment receipts, which are time-consuming, repetitive, and vulnerable to mistakes. The objective of this research is to create and develop a web-based water billing management system to facilitate water usage recording, automatically generate monthly billing recaps, manage payment data, and provide digital payment receipts. The system is analyzed using the PIECES framework and developed using the Waterfall model with PHP, Laravel, and MySQL. The findings indicate that the system is capable of record water usage data, generate monthly reports automatically, display payment status, and provide digital payment receipts. Therefore, the system improves efficiency, accuracy, and transparency in administrative processes at KSM Tirta Lestari Flamboyan.
