Data Visualization of Housing Project in Aceh 's Rehabilitation and Reconstruction using open source software is a good model to transfer knowledge and lesson learn on Disaster Risk Reduction. The distribution of information can be more accessible for community, government, and related institutions in the field. Housing Project to making Aceh Safer Through in Rehabilitation and Reconstruction was a project initiated by Germany Red Cross (GRC) to monitoring and evaluation for the program to know about 'Building capacity Know-How' and 'Culture of Safety' of the housing structure, and therefore it is necessary to know the end-line situation amongst the communities in the project areas. The most important learning of the study is, building houses used local approach is good, but selected materials to install on the area based on landscaping is more important. Regarding to the most frequently hazard in the area.

## 1. Background

Housing Project of Germany Red Cross (GRC) had been implemented in Aceh. The selection`s criteria of study area is in the two city/district at high risk of disasters in Aceh Province. One is housing program inland, which is Calang Region, Aceh Jaya. And one is in the island, which is Sabang City, to compare differences between two programs.

## 2. Objectives

The objectives of the study is (1) to develop Aceh disaster digital archive in order to facilitate sustainability transfer information and knowledge in relation; (2) to give an alternative media on DRR's Education; (3) to get the lesson from the past disaster: (4) to contribute for Disaster Risk Reduction effort in the future: (5) to function as global information for the world: (6) to create a handy tools of DRR.

## 3. Method

There are two steps method of this research: (1) Qualitative research to collecting data. Using primary data for questionnaire, in depth interview and observation by purposive random sampling. Besides using secondary data from literatures. (2) Quantitative research to making archive. Using cesium as an open source data. Linked to the URL. Visualized data and connecting to social network service (SNS).

## 3. Discussion

The percentages of the categories are variation in each village. By Visualization, the landscaping areas preserve better understanding the comparison between housing project inland and in the island.

- Houses Occupied: in Aceh Jaya, majority houses are occupied by original beneficiaries. In Sabang, turned housing by new owners are up $13 \%$.

- Reinforce Concrete Condition (RCC): Majority houses conditions in reinforce concrete \& structures are no damage visible. In Sabang District, the three villages confirmed from $67 \%$ to $87 \%$. In Aceh Jaya the three of villages confirmed from $95 \%$ to $100 \%$.

- Walls: Study shows walls conditions are minor damage visible. in Sabang, the three villages confirmed from $47 \%$ to $78 \%$. In Aceh Jaya the three of villages confirmed from $36 \%$ to $100 \%$.

- Roof In Sabang the three villages confirmed from $50 \%$ to $78 \%$. no damage visible in the roof condition. In Aceh Jaya
the three of villages confirmed from $56 \%$ to $80 \%$.

## 4 Result

## 3. 5 Specific Finding Result

After 5 years, there are some significant differences in each village in Aceh Jaya District. Finding specific result shows: (1) in Blang Village, $87 \%$ confirmed minor damage wells in this area, (2) in Dayah Baro Village, $31 \%$ confirmed minor damage toilet in this area, (3) in Ketapang Village, $69 \%$ confirmed major damage gable in this area, (4) during the earthquake 2012, housing conditions in the two districts confirmed $100 \%$ no damage due to strong construction and community awareness to evacuate to open space. Or higher land, (5) they are satisfied with the project. In Aceh Jaya the three villages confirmed could be improved in the project from $4 \%$ to $42 \%$, (6) in the three villages in Sabang Island, they had no worries in their house when the earthquake occurred, up to $62 \%$. Otherwise, beneficiaries in Aceh Jaya, beneficiaries had worries in their houses when the earthquake occurred, up to $70 \%$ and very worries up to $97 \%$, (7) base on in depth interview with head villages, in the planning of houses shows $50 \%$ satisfied, $33 \%$ acceptable and $17 \%$ very much accepted in the planning of houses in Sabang and Aceh Jaya, (8) and shows $50 \%$ satisfied with implementation the method of housing project in Sabang and Aceh Jaya, (9) beneficiaries self-initiative to extend the houses for economics, (10)

## 4. Conclusion

Characteristic of structure from Germany Red Cross Housing Project in Aceh Jaya has found that the building structure made Increase in community disaster preparedness from hydro-meteorological hazards (flood) because of houses in Second floor, and for geological hazards (earthquake). Characteristic of structure in Sabang has found that the building structure made Increase in community disaster preparedness from hydro-meteorological hazards (typhoon) because of permanent Gable in the structure. For geological hazards (earthquake). Structure of houses just one floor and there isn't drainage around, make houses risk from flooding in the raining season. Local's material approach for housing program is good, but, local identification by visualization landscaping is most important for mitigation of the secondary hazard and better housing program post disaster in the future.
