Information System for Consumables Control of the Department of Public Works, Roads, and Water Resources

Fungky Ariya Wardana — 2026-08-07

This research aims to develop a web-based Information System for Consumable Goods Control at the Department of Public Works, Highways, and Water Resources of Sidoarjo Regency. The primary constraint in this institution lies in the manual inventory recording system, which is prone to data irregularities, reporting delays, and suboptimal stock control. To address these issues, this study employs the Research and Development (R&D) method with a Waterfall development model, encompassing the stages of preparation, system design, implementation, verification, and maintenance. The software is built using the PHP programming language and MySQL database, featuring master data management, transaction recording for incoming and outgoing goods, and real-time stock reporting. Based on the results of black-box testing, the system achieved a 100% success rate, proving that all functions operate according to specifications. The implementation of this system is expected to enhance data accuracy, operational efficiency, and transparency in managing consumable goods.

Designing a Web-Based Information System for Green Open Space Utilization Services

Nihayatur Rohmah — 2026-08-07

The development of an information system in this study was carried out to meet the needs of the Sidoarjo Regency Environment and Sanitation Agency (DLHK) for an integrated system. More specifically, this web-based system was designed to handle services related to the use of Green Open Spaces (RTH), which until now have been dependent on manual processes and have lacked data integration. This condition has the potential to hinder the optimization of management, supervision, and service quality. In building the system, the researchers chose the Waterfall method. The reason is that this method provides clear and sequential stages. We went through these stages, starting from analyzing user needs at DLHK, then designing the system and database, then programming using a specific language, then testing the system, and finally preparing maintenance documents. To ensure that the system runs well, two types of tests were conducted. The first test was a Black Box functional test with 27 scenarios created based on use case schemes. The second test was a User Acceptance Test (UAT) involving potential users to fill out questionnaires. The results of this series of tests were encouraging. In the Black Box test, 96.3% of the functions were recorded as successful. According to the researchers, this figure shows that almost all core features are functioning optimally. Meanwhile, in the UAT, the user satisfaction score reached 91%. Based on our interpretation, this score falls into the "very satisfied" category and proves that the system is well received at the end-user level.

Sidohibah: Web-Based Application for Grant Applications for Private Elementary School Facilities and Infrastructure in Sidoarjo Regency

Kurnia Ningtiyas — 2026-08-07

The process of applying for facilities and infrastructure grants at private elementary schools in Sidoarjo Regency is still mostly handled manually, which sometimes results in delays, recording errors, and difficulties in collecting data for each application. Therefore, researchers developed a web-based information system called Sidohibah. The system was developed in stages, adapting to user needs. The implementation results show that this system is capable of improving administrative efficiency while strengthening transparency in grant management.
