An earthquake measuring 7.6 on the Richter scale Pariaman Padang, West Sumatra, Wednesday (30 / 9) afternoon, and the SR 7.0 in Jambi on Thursday (1 / 10) morning should be an important lesson for us all. It’s nothing, the quake has destroyed everything. Within a flash, the beauty was dimmed Minang realm.

More than 800 people were killed, thousands injured, and thousands of houses collapsed, flat on the ground. Total losses estimated at more than Rp 2 trillion. Areas with the greatest impact is the city of Padang, Pariaman city, Padang Pariaman, Agam regency, Pasaman, and West Pasaman.

According to the writer’s observation after looking directly into the various locations, the majority of construction of damaged homes was not technically qualified (non-engineered housing).

Destruction of homes caused by several things. Among other things, the configuration of the house. Plan irregularity resulting force and torque stress concentration that destroyed the building.

In addition, the house that collapsed had no practical columns, beam circumference (ring balk), and sloof. Without these things, the house collapsed or ambles easily. If anything, it does not meet the requirements.

Imperfections caused connection structural elements are not bound well. Quality materials, like brick, wood, sand, and a low concrete materials, also impacted on the quality of the building.

If poor-quality job of mixing concrete, mortar mix wrong, careless drafting brick, iron wrong details, wood or concrete connection is bad, pengangkeran (anchoring) bad, and so forth, the house collapsed easily. Lack of maintenance also undermines the strength of the building.

Friendly house disaster

Based on these phenomena, it’s time to clean up.

Ministry of Maritime Affairs and Fisheries has initiated the development of disaster-friendly homes since 2006. Until 2008 has been built around 497 houses in 18 districts / cities. The houses that have proved successful and remained standing despite strong earthquake rocked. In City Pariaman and Agam District, for example, all the houses were able to survive.

Likewise, disaster-friendly house built in the South Coastal District. The houses were resistant to SR 7.4 Bengkulu earthquake, Wednesday (12 / 9), two years ago.

In the year 2009 was 2236 units of housing built friendly fishing disaster in 55 districts / cities. In Agam District, of which 50 houses being built, 14 houses collapsed walls earthquake rocked Padang Pariaman. The reason, the new wall as high as 1 meter works and his condition is still wet. Practical columns casted yet, so there is no good bond between the wall and practical fields.

There are two types of homes are developed, namely nonpanggung and stage. For areas outside the tsunami rayapan, nonpanggung shaped house. The tsunami-prone area with a pool depth of the tsunami less than 3 m built houses on stilts.

Formed the stage for a tsunami can freely pass, thereby reducing the horizontal load on structures. On normal days, the basement can be used to relax, parking, kiosk, repairing nets, weigh the fish, and so forth. The floors above it can be used to evacuate when a tsunami.

Building sketch a simple, symmetrical, single unit, and uniforms. The size of an average house 27.5 square meters. The building was made possible parallel to the direction of tsunami waves spreading or perpendicular to the shoreline to the water pressure to the smaller building.

Sloof mounted on the entire length of the foundation to support and flatten the load on the wall above it and forward it to the foundation beneath. Sloof also serves to prevent rising water from the bottom to the top of the wall. Especially for houses on stilts, sloof installed to connect each pole stage and can function as lateral bracing (horizontal amplifier) to the tsunami.

Practical columns are made to strengthen the walls and supporting pillars, installed. 3-meter maximum distance, the couple straight wall and the wall meetings. Block around the function to flatten the load the horses and the roof truss, the framework of the ceiling to the walls, or columns below.

Calculated stage house structure in order to overcome the hard object collision by ships or other objects thrown into the beach. Pole stage house and should be of concrete cylindrical-to touch the field and a collision with floating debris as small as possible.

Foundation of the house-shaped platform soles (foot plate) and connected strongly with sloof and pole houses. The foundations laid 1.5 meters below the surface in order to better durability, in order to hold water gerusan due to swift currents. Tsunamis can erode the soil up to 1.5 meters deep.

Pattern Bantul and Klaten

To build earthquake-resistant houses and tsunami efficiently and effectively, we are worthy of imitation house reconstruction activities by the earthquake in Bantul and Klaten, the model Java Reconstruction Fund (JRF).

Around 6080 earthquake resistant houses are made JRF without bidding. The contractor was involved. Communities implement and supervise the construction of his house directly.

Each head of family whose homes collapsed or were severely damaged received Rp 20 million aid to earthquake-resistant houses 21 m-27 m. Some of them spend personal money for extra homes to be more beautiful and elegant.

In order for the process of development goes according to earthquake resistant housing standards, they were accompanied by a consultant. Consultant co-supervise the implementation of housing, ranging from the quality of building materials to manufacturing techniques home. JRF paid consultants.

Now, the victims were already enjoying the houses are earthquake resistant. Their lives much more calm. More than that, no leakage aid money for various things.
