            val geoLocator = GeoLocator(this@BerangkatKerjaActivity, this@BerangkatKerjaActivity)
            val origin = LatLng(geoLocator.lattitude, geoLocator.longitude) //lokasi terapis sekarang
            val destination = LatLng(-7.781200, 110.349709) //lokasi tujuan
            DrawRouteMaps.getInstance(this)
                    .draw(origin, destination, mMap)
            DrawMarker.getInstance(this).draw(mMap, origin, BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE), "Origin Location") //getting red in this line
            DrawMarker.getInstance(this).draw(mMap, destination, BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE), "Destination Location") //getting red in this line
        } else {
            val service = getSystemService(FragmentActivity.LOCATION_SERVICE) as LocationManager
            val criteria = Criteria()
            val provider = service.getBestProvider(criteria, false)
            val location = service.getLastKnownLocation(provider)
            val userLocation = LatLng(location.latitude, location.longitude)
            val origin = LatLng(userLocation.latitude, userLocation.longitude) //lokasi terapis sekarang
            val destination = LatLng(-7.781200, 110.349709) //lokasi tujuan
            DrawRouteMaps.getInstance(this)
                    .draw(origin, destination, mMap)
            DrawMarker.getInstance(this).draw(mMap, origin, BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE), "Origin Location") //getting red in this line
            DrawMarker.getInstance(this).draw(mMap, destination, BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE), "Destination Location") //getting red in this line
        }
