Abstract

One of the potential utilization of non-timber forests derived from mangrove forests is waste. Waste that may be utilized from mangrove forests is branch and twig waste. It has economic benefits from the mangrove ecosystem as a handicraft material to increase the income of coastal communities. Components of physical, mechanical and natural durability properties are important elements to know in order to distinguish the types of wood and to be categorized for woodworking and wood processing and wood resistance to attack. This study was conducted in order to provide information and data on 3 types of mangroves as craft materials. The method of analyzing physical and mechanical properties was carried out at the Forest Products Technology Laboratory Campus 2 USU and the burial test was carried out in the field, samples with a size of 20 cm. Before testing, the samples were ovenized at 103 ± 5 °C. Then, 15 cm of the sample was buried in the soil, and 5 cm was set aside above the soil surface. The test was conducted for 100 days. After reaching the predetermined time, the sample was cleaned and oven again. Parameters observed included weight loss. The results showed that the values of moisture content, density, MOE, MOR and weight loss were different for each wood species, growth section and location. The grave test of wood durability based on weight loss with the highest percentage to low 34.95%-2.152% so that the highest is found in class I. The species with potential as craft materials based on weight loss are oil mangrove, white fire and teruntun branches from Percut and Rugemuk villages.
