TRAYEK

Illustrative project cover

Project Overview

TRAYEK adalah game routing optimization berbasis peta Indonesia yang menantang pemain menyusun urutan kunjungan rute logistik terefisien melawan solver AI (Nearest-Neighbor, 2-Opt) dan routing engine Valhalla. Menghadapi 8 kendala realistis khas Indonesia seperti ganjil-genap Jakarta, banjir rob pesisir Semarang, jam ibadah, one-way streets, serta koridor logistik IKN across 15 kota Nusantara.

Outcomes & contributions

  • Top 100 #JuaraVibeCoding Season 1 (Mei 2026) oleh Google Developer Groups Live Indonesia & Vertex AI (ID Sertifikat: JVC2605-DFFS-KBGR).
  • Arsitektur microservices dual Cloud Run: Frontend Next.js 16 (TypeScript strict) dan Backend High-Performance Go (Golang) untuk route simulation & attempt cooldown.
  • Self-hosted Valhalla routing engine dengan costing multi-armada (motorcycle, auto, truck) serta pre-baked distance matrix untuk zero-cost runtime routing.
  • Integrasi Vertex AI (Gemini 3.1 Flash) dan Google Search Grounding untuk mission briefing naratif serta penjelasan edukatif kendala logistik lokal.
  • Mencakup 15 kota dari Medan hingga Sorong dengan 36 skenario misi logistik kepulauan.

REST API / JSON/XML Parsing

BMKG Open Data REST API & MCP Server

Developed a modern RESTful API wrapper for the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) open data. This project seamlessly converts legacy XML weather and earthquake data into developer-friendly JSON format. It features a robust Model Context Protocol (MCP) integration, allowing AI agents to natively query real-time Indonesian weather forecasts and seismic activity. The service is optimized for edge deployment on Vercel.

Automated Earthquake & Weather Alert System 2026
Astro / Docker

Automated Earthquake & Weather Alert System

A real-time alerting service designed to monitor the BMKG API and dispatch instant notifications for significant weather events and earthquakes across Indonesia. The system continuously polls the data feeds and pushes formatted alerts to external messaging platforms via webhooks whenever predefined risk thresholds are met. Fully containerized with Docker for easy self-hosted deployment.
