Flood disasters frequently occur throughout all regions
In Jember, the floods occurred two times; at the beginnings of 2006 and 2009. The year 2006 the worst-affected floods was District of Panti. The year 2009, flood disasters occurred in the Districts of Silo. This disaster resulted in damages to homes, fields and both material and immaterial losses . 57 people died, 15 people were missing, tens people were injured, 1900 people were evacuated, 300 people had not been evacuated, 36 houses were swept away, 2400 houses were damaged, six bridges were broken, 140 hectares of rice field were damaged

Surrounding Community at Gumitir and Argopuro mountains. the communities that exist at the surroundings of the mountains, the Districts of Panti and Silo. Samples were taken 'in a balance' with a total of 100 samples. The number of samples was divided for each region and population.
RESEARCH AREA
The data used in research were:
vulnerability and capability.
taken from the village office, the Central Bureau of Statistics and others.
There are three main elements in this qualitative research.
data, which could be derived from
2003:7).
m AxK R =
R = Risk of Disaster; A = threat; K = vulnerability; m = ability (ISDR, 2004) There risk measured by:
The Geology of Jember Regency consists of Young Volcano sediment (sandstone ) which has good properties to flow the water
The slope over 15 percent (30 degree) makes the watershed of District of Panti vulnerable to soil movement potential.
The slope over 15 percent (30 degree) makes the watershed of Silo District vulnerable to soil movement potential.
In Silo, whose altruistic spirit remained high both before and after the disaster. Unlike Silo, Panti made the spirit of mutual help among residents (altruism) of Panti community that was originally fair become high.
In Silo, There was no structured mechanism in running the early warning system. Everything was spontaneous and modest. While, Panti Community described their early warning system was structured mechanism.
The majority of officers and the community in Silo stated that the Executing Unit for Disaster Management has none of the six functions This is contrary to Panti residents and officials where that the Executing Unit for Disaster Management in their region already had run the six functions.
Communities and Local Government awareness about flash floods can be seen from the things done, starting from the normal condition, the condition of pre-flash flood occurrence to the condition of early warning and evacuation.
The performance
government preparedness in facing disaster. It was only Panti that had had the map
disaster-prone, but the condition was still not perfect.
Both in Silo and in Panti, most respondents were with lower education (primary school graduation).
The majority of respondents were self-employed and farmers with their respective percentages of 32% and 28%, either as owning farmers, working farmers or the combination of both (owners and workers).
Majority of respondents in Silo and Panti did not have second jobs exactly (75%)and (73%).
In Panti the average income of people in disaster areas was IDR 415,000, while in Silo was IDR 395,000 per month.
Flood disasters in the Districts of Silo and Panti were caused by natural dams clogged by sediment from landslides and erosion in upstream areas. In Panti area, debris materials were boulder-sized while those in Silo area were mud and remnant materials of logging which were more than boulder-sized materials. The potential amount of sediment or potential source of sediment in the area of Panti and Silo was materials derived from volcanically sedimentary deposits and the effect of slope and rain.
Based on the physical, social, institutional and economic conditions of communities in the disaster area, the following vulnerability matrix can be made.
Based on the conditions of threats and capacities, the risk of disaster in Jember regency is highly susceptible to floods disaster because of physical condition While the economy that is quite low less supports the disaster mitigation. However, with the social conditions that can be relied upon to cope with the flood disaster, a set
made in the disaster-affected areas for disaster anticipation and post-disaster mitigation.
Disaster management will run effectively and efficiently if there is cooperation between government, private and public, especially in the surroundings of disasters-prone areas (Silo and Panti). Local Government of Jember needs to prepare strategies related to empowerment and increase of participation of communities as well as nongovernmental organizations (NGOs) . It is very necessary because it will greatly assist local governments in protecting the public from the threat
activities to be carried out in disaster anticipation;
destructors by involving the public, private, and NGOs,
relationships
dissemination and advocacy efforts to the public
and completing the equipment used at the time before the disaster and the aftermath of disasters
awareness to the public in disaster prone areas
The programs that can be implemented by Local Government are:
that have already existed (Executing Unit Coordinators, Executing Units, NGOs and Indonesian Red Cross);
non-governmental actors;
propose policy as well as a means of coordination;
communities as a priority, and local government is supportive;
and making it a routine mechanism.
Based on field observation and analysis results, it can be concluded that:
conditions at the disaster sites are vulnerable enough 2. Spirit of mutual help among people in disaster areas is quite high. 3. Community institutional arrangement Panti is solid enough either in cope with disasters, while in Silo existing institutional arrangement is less solid. 4. Economic condition in the disaster area is categorized low.
than in Panti.
arrangement, people's knowledge about flash flood disaster and disaster management training are necessary.
productive economic sectors in the disaster area is needed on the basis of existing resources around the disaster sites.
flood disasters can be done by creating a set
arrangement in flood disaster-affected community.
