Introduction – Tidal flood is one of the problems found in Semarang.

• – Rising Sea level and land subsidence contributed to the problem of tidal flood.

  It is reported that the area close to Kemijen has land subsidence around 13.5 cm / year.

• – Community in Kemijen is struggling with this environmental problem by raising the floor of their house to prevent tidal flood entering the house

The other practical solution which has been done by Kemijen community is raising the road surface. As a result the

height of the house becomes low compare

to the road surface.

  Problems – The elevation of the environmental road surface is only temporary solution.

  Street elevation is useful for people's access to daily activities. However, it caused a new problem for the poor/ low income people because they could not raise their houses so that the floor surface was lower than the street level.

• – By looking at the background above, the problem of the proposed research is how to design a house which is able to adjust with rob/tidal flood, without putting more soil to the floor for raising the level of the floor
• – The first research was to develop a model design of adaptif hydrolic bamboo house, then the second step applied the design to the real location, the area which was suffered from the tidal flood

Methodology

• – The location is in RW IV, the most heavily inundated areas in Kemijen.
• – Observation, interview and FGD were used to get the data and to

  get informed about the environment condition and the need of

  the community

• – Considerations for choosing the location the family who has low

  financial ability and 2) the condition of the house which is not suitable for living

Desain adaptif hydrolic bamboo house

  

The Adapative House model is in the form of a hydraulic stage built 1.5 meters above the road

(house on stilts) can be used to overcome flooding or tidal flooding for 5-10 years. If the water

has reached the surface of the house, the floor of the house can be raised. Once raised as high

as 50 cm, it is sufficient for 3-5 years

  Purpose of introducing Adaptif Hydrolic Bamboo House

• – Research related to bamboo house design is made as an alternative solution for

  Kemijen people, especially those with low income

• – With the social capital that is owned by the Kemijen community (gotong royong), the construction of a hydraulic stilt house made of bamboo will be able to be built well because the costs can be cheaper, and the togetherness between people in the community can be maintained.

Location

  Stages in the application of hydraulic bamboo houses

• – Focus Group Discussion
• – Socialization of the design was done through the FGD. The input from the community that came was very helpful to improve the hydraulic house design, in accordance with the local environment and in accordance with their needs. Through the FGD, the location where the design would be applied was decided by agree
• – Stages of development of the house:
• – 1) Preparation works, 2) Bamboo preservation and installation for foundation
• – 3) Instalation of sloof
• – 4) Galvanized pipe installation (hydraulic pole)
• – – 5) Instalation of flooring stilt house 6) Hydraulics Test of the House Pole stage

Preparation Works

• – Land clearing where bamboo hydraulics will be built
• – Form of participation: Clearing the location, done by the Heri family and some of the residents next to his house. This work is carried out mainly by male residents. On normal days not many residents can help because they also have to work,

Bamboo preservation – The bamboo to be used must be put in the water first so that it lasts longer.

• – Form of participation: Because the amount of bamboo is quite a lot so it cannot be soaked only on the land next to the house, so it is needed to find anther location. By deliberation, it was finally agreed to use a pond near the house that could be used for soaking. The immersion process is carried out together with the the craftsman, the owner of the house and a number of nearby residents

Installation of Sloof, Galvanized Pipe Installation (Hydraulic Pole) and Installation of Stage House Floors .

• – Form of participation: – Very limited, need skills, can only be done by expert/craft
• – Participation from women by providing snack

Instalation of house floors

• – In this step, community participation began to be seen again. Here the floor of a stage house made of bamboo starts to be prepared. Bamboo that has been soaked for a long time is then taken, and then prepared to be used as floor material.
• – The removal of bamboo from the immersion site was carried out together with craftmen, homeowners and several community members, then some of them began to help to cut bamboo according to needs. All this work is done voluntarily

Hydrolic Test of the Adaptif house

• – This hydraulic house test is carried out by raising the galvanized pole, so that the floor of the stage house moves up. Jack / tipping tool used is a car jack with a maximum load of 5 ton. Therefore, the building materials chosen and used in the construction of houses are lightweight materials, such as bamboo and mild steel.
• – It takes at least 4 people to jointly raise the hydraulic pole. There are 4 poles that must be lifted / jacked together. Participation of male citizens from nearby neighbours

Conclusion

• – In connection with community involvement in the construction of this bamboo-based hydraulic house, community participation was more visible when the community was asked to provide input on the hydraulic house design in the FGD forum. In this case participation can be seen in the form of input and thought, not participation in physical form
• – Participation in physical form was found at several stages of development, but the people involved were only residents whose houses were close to the location of the hydraulic house construction, while during the FGD and design socialization, more people came
• – Learning process in everystage, some people who are interested to know about how to build this house came and discuss with the team. It is hope that they understand every stages, how each stage is carried out and so on, so they can build b themselves

Conclusion

• – Obstac>

  – Activities are carried out on weekdays (because they also involve a worker), so that residents can only help on free time or when they are not working.

• – Some of the work is done by requiring skills or technical skills so that residents can only participate in work that does not require expertise or skills

• – Although according to residents of mutual cooperation activities by involving citizens is not as easy as before, but in certain conditions where the community considers the

  problem is a common problem, community participation can still be expected.
