Automated ladder over-limit reports using PostgreSQL and Google Looker Studio at PT Profesional Telekomunikasi Indonesia (Jakarta)

During my internship at PT Profesional Telekomunikasi Indonesia (Protelindo), I was placed in the PAAS Division as part of the Performance team, where I was responsible for developing a real-time monitoring dashboard using Google Looker Studio integrated with PostgreSQL. This dashboard visualized power consumption data from tenants, sourced directly from RTU server outputs, and provided insights into whether power usage exceeded the agreed contractual limits. The solution supported management in making informed decisions by analyzing power efficiency, system reliability, and overall consumption trends. I was also involved in collecting and analyzing BTS power system performance, identifying anomalies, investigating root causes, and preparing regular performance reports for both technical and managerial teams.
