  A landing page for TB. Sahabat Sentarum, a building supply store in Pontianak, live at sahabatsentarum.my.id. The store sells the same tank and pipe brands as every other shop in town, so the copy sells the store instead of the product: delivery to the site, a free fitting with tanks, competitive prices, help with warranty claims, and the one official WhatsApp number shown as a scam warning, because fake accounts impersonate the shop. Outcome: 14 tank types.

Research

• Quantization Effects on Explainability in Indonesian Transformer-Based Sentiment Analysis

  Quantization Effects on Explainability in Indonesian Transformer-Based Sentiment Analysis is a 2026 research paper by Helena Aurelia Sanjaya, Marvel Collin, Bertrand Geraldo Tjahyadi and Prof. Derwin Suhartono.

  Research on applying model quantization techniques to sentiment analysis tasks. Includes multi-seed evaluation, explainable AI (XAI) analysis, statistical testing, and NusaX benchmark evaluation. Investigates how quantized models perform compared to full-precision baselines on Indonesian language sentiment data. Published in Procedia Computer Science (ICCSCI 2026).

• Efficient Reasoning for Competitive Programming: Precision Limits of Knowledge Distillation and Post-Training Quantization of Large Language Models

  Efficient Reasoning for Competitive Programming: Precision Limits of Knowledge Distillation and Post-Training Quantization of Large Language Models is a 2026 research paper by Marvel Collin, Bertrand Geraldo Tjahyadi, Helena Aurelia Sanjaya and Prof. Derwin Suhartono.

  Distills a DeepSeek-R1-Distill-Qwen-7B teacher into a 1.5B student on unit-test-verified LeetCode reasoning traces, then tests whether the distillation gain survives post-training quantization. The gain holds at INT8 but not at 4 bits, and weight-space measurements of kurtosis, tail mass and quantization error explain why. Under review at IEEE Access.
