At this time began to be revived the use of local materials. This is based on aesthetic and economic considerations. Therefore, researchers are encouraged to examine the knowledge of the utilization of local resources, especially nipah leaves. In Petoaha Sub District, Abeli District, Kendari City is located Kampung KB (Family Planning). Kampung KB is a former village of Bajo ethnic landed (formerly living on water). Mothers in Kampung KB are busy making roof material from nipah leaves. The leaves are taken from the palm trees that grow around Kampung KB. The phenomenon in the field that leaves soaked in sea water for 1-3 days before the roof is made. According to them that the leaves are soaked in sea water has a long lifetime compared to leaves that are not soaked in sea water. Based on their experience that watersoaked leaves have a lifetime for 3-4 years, can even reach 6-7 years when the roof thickness reaches 10 layers of palm leaves. Nipah leaves do not soak sea water has age wear for 2-3 years. This research is aimed to test the nipah leaf of marine water and nipah leaves do not soak the sea water against the period of usage. Metode plate count digunakan dalam penelitian ini. The plate count method to test the total microbial between fresh nipah leaf and nipah leaves is soaked in sea water. This study concluded that the bacteria on the nipah leaf soak the sea water is lower. Nipah leaves soaked sea water has a lifetime longer than nipah leaves do not soak sea water made roof material.
