## 🗺️ Konstanta Wilayah (44 Kecamatan DKI Jakarta)
Untuk memetakan wilayah pada leaflet/map atau drop-down pilihan di FE, gunakan konstanta koordinat dan baseline berikut:

```typescript
export interface RegionMetadata {
  latitude: number;
  longitude: number;
  normal_avg: number;
  warning_threshold: number;
  critical_threshold: number;
  city: 'Jakarta Pusat' | 'Jakarta Utara' | 'Jakarta Barat' | 'Jakarta Selatan' | 'Jakarta Timur' | 'Kepulauan Seribu';
}

## ⚡ Contoh Integrasi Frontend (Axios / JavaScript)

Berikut adalah contoh cara menarik data prediksi Autopilot dan memuatnya ke komponen halaman FE Anda:

```javascript
import axios from 'axios';

const BACKEND_URL = 'http://localhost:8001';

// 1. Memuat Umpan Berita AI
export async function getWasteNews() {
  try {
    const res = await axios.get(`${BACKEND_URL}/api/v1/news`);
    return res.data; // Mengembalikan array berita
  } catch (error) {
    console.error("Gagal menarik berita sampah:", error);
    return [];
  }
}

// 2. Memuat Data Autopilot Otonom DKI
export async function getAutopilotData() {
  try {
    const res = await axios.get(`${BACKEND_URL}/api/v1/autopilot`);
    return res.data;
  } catch (error) {
    console.error("Gagal memuat autopilot data:", error);
    return null;
  }
}

// 3. Menjalankan Prediksi Manual (Simulation)
export async function postSimulationPrediction(kecamatan, hari = 7, model = 'gradient_boosting') {
  const payload = {
    forecast_days: hari,
    rainfall_mm: 0.0, // Auto
    event_scale: 0,
    location: kecamatan,
    granularity: hari <= 7 ? 'hourly' : 'daily',
    model_type: model
  };

  try {
    const res = await axios.post(`${BACKEND_URL}/api/v1/predict`, payload);
    return res.data;
  } catch (error) {
    console.error("Gagal melakukan prediksi simulasi:", error);
    throw error;
  }
}
```
