Pennyu Indonesia

Data Analyst • Kemnaker Internship Program

Delivered 6 business case projects across marketing, operations, and PPIC, translating data into actionable business insights.
Analyzed promotion impact on customer behavior, identifying increased engagement but low conversion and uneven segment performance → recommended more targeted and efficient promo strategy.
Evaluated GPS implementation on fuel efficiency, uncovering inconsistent results driven by driver behavior, idle time, and data issues → recommended stronger SOP enforcement and monitoring to optimize fuel efficiency.
Developed a custom web dashboard to overcome Looker Studio limitations, enhancing route visualization and analysis capabilities.
Evaluated route efficiency and sales discipline, identifying travel inefficiencies → improved route efficiency by 9% through optimized routing.
Analyzed outlet visit behavior using correlation methods, identifying visit frequency as the key driver of transaction and activation → recommended increasing visit intensity on high-potential outlets.
Validated PPIC planning accuracy by comparing plan vs demand, identifying misaligned buffer logic → redesigned data-driven buffer approach, reducing planning deviation by >95%.
Built 15+ pages of Looker Studio & web-based dashboards, standardizing data and improving visibility for KPI, performance, and operational monitoring.
Collaborated with data analysts, data engineers, and IT teams in data discussions, analysis, and solution development.
Shared knowledge on web dashboard development with data teams (analysts & engineers) to improve analytical capabilities.
Delivered AI-related material in Pennyu Learning Circles and participated in 10+ internal sessions.
