Abstract

Village-owned drinking water enterprises in Indonesia have required better tools for metering, billing, and payment to replace fragmented paper-based workflows. This work aimed to design, implement, and evaluate a web-based information system (PAMDESKU) for a village water enterprise, while strengthening local capacity through the Asset-Based Community Development (ABCD) approach. A web-based application was developed and deployed with modules for customer data, tariffs, meter readings, billing, payments, and reporting, alongside safeguards for authorization, logging, and backup, which was named PAMDESKU. Baseline usability had been poor; after implementation and mentoring, the SUS score increased to the “Good to Use” range, with concurrent reductions in data entry errors and reporting time and improved transparency of billing information. The coupling of ABCD with end-to-end digitalization enabled a locally owned and sustainable service transformation. The approach yielded measurable usability and efficiency improvements and offers a replicable pathway for other village enterprises pursuing Smart Village objectives.

Abstract

Moodle is a widely used Learning Management System in various educational institutions worldwide. However, frequent reports on internet forums indicate performance degradation when massive simultaneous users access Moodle. One of the most resource-intensive components supporting Moodle is the database, as all user-accessed data is stored in it. This study aims to optimize Moodle’s performance through distributed databases. Distributing the database into multiple database servers allows the database load to be distributed across all the database servers, resulting in an overall improvement in Moodle performance. This study compares the performance of Moodle installed on a single server with that installed on multiple database servers. Various testing parameters are employed to get valid results. Namely, course read, course write, and database performance, utilizing the server performance plugin available in Moodle. This research reveals a performance improvement of 384% in course read, 193% in course write, and 260% in the Moodle database in the multi-server scenario compared to the single-server scenario. This result validates that the database is the most crucial part of Moodle.
