### 2. Visual Indicator
- **Dev Chip**: Chip orange dengan text 'dev' 
- **Positioning**: Muncul setelah text menu di expansion items
- **Styling**: Size xs, orange background, white text
- **Responsive**: Konsisten di semua ukuran layar

### 3. Menu Items Updated

## Technical Implementation

### Environment Files
```bash
# .env.development
VITE_APP_ENV=development

# .env.production  
VITE_APP_ENV=production
```

### Vue Component Changes
```vue
<script>
import { defineComponent, ref, onMounted, computed } from 'vue'

// Development environment detection
const isDevelopment = computed(() => {
  return import.meta.env.VITE_APP_ENV === 'development'
})
</script>

<template>
<!-- Expansion Item with Dev Chip -->
<q-expansion-item>
  <template v-slot:header>
    <q-item-section avatar>
      <q-icon name="history" />
    </q-item-section>
    <q-item-section>
      History
      <q-chip 
        v-if="isDevelopment" 
        size="xs" 
        color="orange" 
        text-color="white" 
        class="q-ml-sm"
      >
        dev
      </q-chip>
    </q-item-section>
  </template>
</q-expansion-item>
</template>
```

## Files Modified

### 1. MainLayout.vue
- **Path**: `frontend/src/layouts/MainLayout.vue`
- **Changes**:
  - Added `computed` import
  - Added `isDevelopment` computed property

## Visual Result

### Development Mode (localhost:5173)

   # Lihat sidebar - chip 'dev' harus muncul
   ```

2. **Production Build**:
   ```bash
   cd frontend
   npm run build
   # Deploy ke production server
