Mangrove is a coastal plant which is vurneable to heavy metal pollution , whether from land or from the sea . More industrial development resulted in high levels of waste pollution .Various industrial waste into coastal waters will threat coastal vegetation like as mangrove. Rhizophora mucronata is one kind of mangrove with the highest population and is most often found around the coastal areas. Many industrial activities dischange lead (Pb), where Pb is one of the heavy metals that can not be degraded, can be accumulated in organism. This study aimed to know the accumulation of plumbum in mangrove the influence of difference concentration of Pb and exposure duration on chlorophyll content of R. mucronata mangrove leaves. The research was conducted in July-August 2012 at the Marine Science Campus , Faculty of Fisheries and Marine Science , Diponegoro University , Semarang. Mangrove saplings used was R. mucronata ± 8 months old . Mangrove test was placed on the test media with concentrations of 20 , 100 , and 500 ppm . Each treatment was triplicates and analysis for chlorophyll content was done every 10 days. The results of study can be concluded that the greater Pb concentration the longer the exposure time could decrease of chlorophyll content. But despite the amount of chlorophyll decreased, based on the calculation of the value of phytoremediation (FTD) R. mucronata still be potencial to reduce pollutant movement of Pb in soil/sediment/

Lignin is one of the principal components constituting wood bulk, besides cellulose and hemi cellulose. It consists of poly-phenolic molecules, serving as a binding agent, which holds the wood cells together. Lignin is also credited with imparting rigidity or stiffness to the wood, rendering its body effectively resistant to the mechanical forces imposed on it. Considering and evaluating the specific attributes of lignin, an idea has come-up to utilize it as a binder or glue in the manufacture of particleboard, plywood, or other wood products.The lignin in the sulphate’s black liquor (known as Kraft lignin) has a strong affinity when being reacted with formaldehyde to form lignin formaldehyde adhesives; and to increase the bonding strength quality, the lignin is further co-polymerization with resorcinol to form lignin resorcinol formaldehyde (LRF) resins. The resin can be employed in the manufacture of particular glued wood products such as finger-jointed wood assembly and glue laminated lumber (glulam). The research was aimed to determine the optimum composition of mole ratio in LRF glue and its pressing duration in laminated wood manufacture for construction qualities with high durability on against dry wood termite. The adhesive was prepared by mixing the isolated lignin, resorcinol and formaldehyde at various mole ratios L : R : F ( 1 : 0.5 : 2; 1 : 0,7 : 2; 1: 0,9 : 2 and control) respectively, and the pressing duration was employed by 3, 6, 12 and 24 hours at room temperature. The research results showed that the higher the resorcinol content, the longer pressing time, the higher the mortality and the lower weight loss. The mortality reaches 91.67 % and weight loss 2.17 %.
