## 🎥 Recording Script (Monologue)

### 🎙️ Part 1: Greeting & Introduction
**[Visual Cue: Start on camera. Smile, look directly at the lens. Have the title slide of the project behind you or overlayed on screen.]**

*   **Faril**: "Hello, distinguished judges. My name is **Faril Putra Pratama**, and I am the **AI Engineer** behind Aeterna AI."
*   **Faril**: "My primary goal for this project was to transition Jakarta’s waste management from a reactive, delayed operation into a highly accurate, predictive system. To achieve this, we developed a state-of-the-art predictive engine."

---

### 🎙️ Part 2: Data Sources & Baseline
**[Visual Cue: Cut to screen share showing the datasets folder or list_dir layout in your editor, specifically highlighting 'dataset_vibe_coder_2026.csv'.]**

*   **Faril**: "Everything starts with the data. We calibrated our system using official baseline data from the **Dinas Lingkungan Hidup DKI Jakarta** and the **SIPSN Ministry of Environment and Forestry**, establishing a city-wide generation baseline of **8,020 tons of waste per day**."

---

### 🎙️ Part 3: ML Modeling & GridSearchCV Tuning
**[Visual Cue: Transition the screen share to show the model training code in 'train.py', highlighting the Gradient Boosting Regressor definition and the GridSearchCV parameters.]**

*   **Faril**: "To turn this data into actionable insights, we engineered a hybrid machine learning model. Our core engine uses a **Gradient Boosting Regressor (GBR)**.
*   **Faril**: "Instead of relying on default values, we executed **GridSearchCV** with Cross-Validation to automatically search for the optimal hyperparameters. The resulting optimal parameters are **100 decision tree estimators**, a learning rate of **0.03**, and a max depth of **3**."

---

### 🎙️ Part 4: Dynamic Feature Engineering
**[Visual Cue: Point to slides or diagrams showing the multipliers: 1) Open-Meteo precipitation graph, and 2) Event calendar listing with crowd scale multipliers.]**

*   **Faril**: "What makes Aeterna AI unique is how it dynamically responds to external variables:
    *   First, we integrated **Live Weather Forecasts** by pulling precipitation data directly from the **Open-Meteo API** based on the precise latitude and longitude of each kecamatan. Hujan lebat increases the moisture absorption of waste. Our model applies a math multiplier adding **2% to 5%** weight to the daily total based on rainfall.
    *   Second, we built a **Location-Aware Event Engine** that scans the Jakarta 2026 event calendar. If a major event is detected, our model dynamically injects a crowd scale multiplier of **10% to 35%** to predict plastic and packaging waste surges."

---

### 🎙️ Part 5: Model Accuracy Validation (The Pitch)
**[Visual Cue: Display a high-contrast slide showing the metrik comparison table: MAE: 132.29 Ton, RMSE: 165.46 Ton, R²: 81.51%, and MAPE: 1.59% highlighted in a bright green neon border.]**

*   **Faril**: "The results speak for themselves. In validation tests, our GBR model achieved:
    *   An **R-Squared score of 81.51%**, meaning our engineered features explain over 81% of the daily waste fluctuations.
    *   A **Mean Absolute Percentage Error (MAPE) of just 1.59%**. In statistics, any MAPE under 10% is classified as *Highly Accurate Forecasting*, and our model sits comfortably under 2%.
    *   Furthermore, our **MAE stands at 132.29 Tons** and **RMSE at 165.46 Tons**, ensuring predictions are highly stable with zero extreme spikes."
*   **Faril**: "Lastly, for long-term 30-day baseline forecasting, we integrated a pre-trained **Amazon Chronos-T5** deep-learning transformer model, which handles time-series predictions when contextual parameters are absent."

---

### 🎙️ Part 6: Outro / Handover
**[Visual Cue: Transition back to camera. Confident nod.]**

*   **Faril**: "With this high-accuracy ML engine, Aeterna AI provides a highly reliable forecasting foundation for Jakarta’s waste management logistics. Now, Bagas will take you through the System Architecture and our Laravel Backend Gateway."
*   **Faril**: "Thank you."

**[Visual Cue: Fade to black or transition to Bagas's segment.]**
