01 — About

I'm a fresh graduate at Universitas Muhammadiyah Prof. Dr. Hamka with a strong interest in data, especially data analysis and data science. I enjoy working with data to find patterns and turn information into meaningful insight that supports decision-making. To me, data is a story waiting to be uncovered through the right approach.

My interest in mathematics and statistics helps me understand data more deeply, both in computational logic and result interpretation. I keep developing my skills across different tools and techniques, hoping to contribute data-driven solutions that create real impact.

Evaluating Subscription Program Effectiveness

A retail company's subscription program had never been evaluated with data, despite being central to its retention strategy — built from 3,900 transactions.

Key findings

  • Adoption is low and skewed by gender — 40% male vs. 0% female subscribed
  • Subscription doesn't lift spending or cut discount reliance ($59.5 vs. $59.9)
  • Revenue concentrates in customers aged 46+, in Clothing & Accessories

Recommendations

  • Redesign the program to be gender-inclusive
  • Shift from blanket discounts to loyalty-driven incentives
  • Prioritize retention campaigns for the 46+ segment
  • Explore demand-building for Outerwear

Netflix TV Show Catalog Analysis

Netflix needs to understand its TV show catalog composition and performance to guide content acquisition, localization, and rating decisions.

Key findings

  • Dramas dominate the catalog — 1,600 titles, far ahead of other genres
  • The US leads production (~800 titles); international markets remain underdeveloped
  • TV-MA is the most common rating (1,145 titles); family content is minimal

Recommendations

  • Diversify ratings by investing in TV-G / TV-Y7 content
  • Expand non-US acquisition — Korea, Spain, France
  • Focus investment on high-performing genres while maintaining niche ones

Movie Recommendation System (Collaborative Filtering)

An item-based collaborative filtering engine on the MovieLens dataset, recommending movies by shared audience behavior rather than genre.

Users and movies with too few ratings are filtered out to keep the data manageable, then a sparse user-item matrix is built from what remains. Item-item cosine similarity measures how closely movies relate based on shared rating patterns, ranking the most similar titles for any query — searching "Toy Story" surfaces Toy Story 2, Forrest Gump, and Back to the Future, purely from shared audience taste.

Mindscroll — Classifying TikTok Scrolling Behavior with Decision Tree

My undergraduate thesis classifies TikTok users into 3 mindless-scrolling categories (Low, Moderate, High) based on two variables: Scroll Behavior (frequency, duration, dwell-time, overuse) and Mindless Scrolling (entry point, normative dissociation, exit point), using survey data from 359 TikTok users aged 18+. After Data Selection, Preprocessing, Transformation, and Categorization stages, a Decision Tree model was tested across 3 scenarios — the best-performing model combined both variables (X+Y), reaching 81.48% accuracy and a 0.8875 macro AUC-ROC, with perfect recall (1.00) for the Low category. The model was then deployed into a website called "Mindscroll" so users can get their classification results directly.
