The Development of Natural Rubber Composite Based Canal Blocking to Sustain Peatland Environment

Abstract:

Peatland fire became a serious problem in Indonesia until nowadays. The most problem of peat fire was caused by converting peatland become plantation area, wherein need canal blocking to adjust water ground as crop planting requirement in peatland. The structure design of this canal blocking should be strong enough to block excessive water level degradation so that can sustain the peatland environment. The current design of canal blocking was used wood as building structure, which has nor water-resistant, therefore, it can be rotten and easy to collapse. Indonesian Rubber Research Institute (IRRI) has already developed novel technology of canal blocking, namely natural rubber composite based water level canal blocking to overcome this problem. This novel technology was used natural rubber composite as material structure, therefore it has higher water-resistant, longer service life, and higher acid resistance than traditional canal blocking. In addition, novel canal blocking has equipped with water level system, which could control the groundwater level were suitable enough for crop planting requirement in peatland. Indeed, novel canal blocking could sustain peatland environment through peatland fire risk reduction, carbon dioxide (CO₂) emission reduction and increase peatland plantation production. This technology has already installed in South Sumatera. Present work would be detailed review structure strength novel canal blocking, environment and economic impact on its application. The application result had determined successful to reduce CO₂ emissions up to 3,723.38 ton CO₂ /ha during 7 months installation. Furthermore, the production of the intercropping system (palm oil and corn) in peatland within novel canal blocking was increasing the profit wherein the B/C of novel canal blocking application was 1.77, while traditional design canal blocking application was 1.55.
