Extensification of palm plantation has significantly increase land fire hazards, which is difficult to extinguish. One of the effective land fire fighting is by using foaming agent, which is mostly imported and expensive. This innovation formulates environmentally friendly foaming agent through saponification process of fatty acids and methyl ester of palm oil. This foaming agent is biodegradable, so that it is safe for the environment. The foam concentrate has a good foam stability up to the third day (77-91%).
