## Conceptual framework

## Data

## Final regression model
```{block}
LTIME = +0.2663 * CARVOLUME + 0.6984 * LLENGTH + 0.0203 * LPOP + 0.0605 * TWOWAY + 0.1681 * SCHOOL + 0.0317 * RESIDENTIAL - 0.5497
```
## Studi Kasus : Pemodelan SIG
### Analisis Wilayah Layanan (Service Area Analyses)
1. Load layer jalan dan fasilitas kesehatan dalam format UTM (Zona 48N).
2. Load raster kepadatan penduduk
3. Melakukan analisis ***service area***
- Processing > Network analyses > Service area
4. Create buffer from service area lines
5. Calculate raster using vector
- Zonal statistics
### Menghitung jumlah rumah di sempadan sungai
