Spatial planning

should

accommodate

human activities,

realize the integrity

of human activities

and available space,

and realize the

protection towards

negative impacts of

space utilization,

including: disaster

risk vulnerability

Spatial Planning Policies based on disaster mitigation are

directly integrated on Spatial Plan Documents (RTRW)

Level

Zoning Regulation agreed by all the stakeholders related to spatial planning should

include acceptable risk level as an integral part of the detailed spatial plan (RRTR)

and stipulated as a legal document that have legal binding

Identification of physical

condition of the area in the

formulation of RTRW

A. Pre Disaster

1. Identification of the disaster

risk level2. Identification of land

suitability

3. Direction of suitable land

utilization

4. Limitation of development in

disaster-prone areas which

has low land-suitability level5. Formulation of space pattern

plan, including the

distribution of conservation

and cultivation areas



6/19

6. Space utilization rule for conservationarea as well as cultivation area is

stipulated in the detailed spatial plan

(RRTR), as the basic of the establishment

and implementation of zoning regulation.

7. Zoning Regulation consists of: prohibition,limitation, conditional permit, additional

rules as well as exceptions in accordance

with the classification of the risk level of

each disaster-prone area (high, medium,

and low).

8. Determination of the evacuation zone andits public and social facilities used as the

service center, in anticipation of the

beginning of disaster crisis era.

C. Post Disaster

Review of RTRW in order to create a more sensitive

spatial plan to minimize the negative impacts of disaster

in the future:o Re-identification of disaster vulnerability level of an area;

o Improvement of the quality of services (information system,

etc.)

o Determination and implementation of the current disaster

management (rehabilitation, reconstruction, relocation,

resettlement)

o Evaluation of space allocation and space utilization

o Severe restrictions, both for space allocation and space

utilization

THE EVACUATION OF

DISASTER , DISASTER

MITIGATION PVMBG 2004

There are about 113 places of refuge

which remains to be verifiedwhether all utilized

Volcano Observation Post is located

in Kediri

There disaster mitigation building

scattered around Kelud mainly to

accommodate the flow of lava ,

among others, control weir lava ;

lava pockets , consolidation dam ;and lava dikes

VOLCANOS ARE LOCATED ON THE

DISASTER PRONE AREA 1.

ONE OF THE CAUSES IS THAT THERE ARE

CONSIDERABLE NUMBER OF EXISTINGRESIDENTIAL AREAS LOCATED ALONG THE

RIVER THUS CAN BE EFFECTED BY LAVA

FLOW.

THERE ARE 865 LOCATIONS (OUT OF 2979
