SABO-TECHNO AS CLEAN TECHNOLOGY

During several last years there are some misperceptions that Sabo-techno is related to a big scale massive structure with an expensive cost, in additional some said that it is only a useless monument because its function only can be seen when debris flow occurred which is very rarely event. So the community can not experience its function directly. Furthermore by the end of 20th centaury when the environment issues become more important, Sabo-techno is accused for causing damages on river morphology and ecology-system. The fact that its function will protect the community in the downstream from debris mass movement was not realized at all. For an instance in case if there are no Sabo dams in Boyong River (BO-D6 structure) then debris mass movement from Mount Merapi lahar in 1994 will effect greater numbers of victims.

Sabo works is not always identically to civil engineering structure. Although early warning system is also one part of comprehensive Sabo works, so are hillside works such as reforestation, regreening, and grass planting on dike revetment. It is to be notice that the implementation of Sabo-Techno through vegetative approach (non-structure) is important and unsubstitude as ecological aspect. Even though it has to be realized that the approach is along term activity which is took longer time has many obstacles to be applied in the hillside than structure approach. It is the reasons why structure approach as a quick yielding action also important to be combining.

The meaning of development is to achieve a better condition in the future by doing changes on present condition. The purpose of Sabo-Techno implementation in the future is first, to protect the community and its property from debris mass movement disaster and give secure feeling to them; second, to maintain natural resources sustainable and improve the surround environment; third, to protect the productive and public infrastructure area from debris mass movement.

If the implementation of Sabo-techno could be develop and applied in a proper and wise approach then it should not be emphasized to state that Sabo-Techno is a CLEAN TECHNOLOGY.
