Abstract

At the moment, plants use as medicine are mostlyland plants, while plants derived from water such asmangroves have not received much attentions.Some of the mangrove plants that can be used asmedicine are Acanthus ilicifolius, Avicennia alba,Avicennia marina, Avicennia offinalis, Bruguieracylindrical, Bruguiera exaristata, Bruguieragymnorrhiza, Ceriops tagal, Hisbiscus tiliaceus,Ipomoea pes-capre, Lumnitzera racemosa, Nypafructicans, Pluchea indica Rhizophora apiculata,Soneratia sp., dan Sonneratia alba. The plants wereutilized as antiasma, antidiuretic, antidiabetic, itchrelieve, etc. Purnobasuki, 2004).One of the mangroves that are often found on theEast Coast of Surabaya, East Java is Soneratia sp ..which is classed as true mangrove flora.Ethnobotanically, the wood and stem are used astraditional medicine as pain reliever. Based onresearch conducted by Mahmiah (2012)studyingphytochemical aspect of Avicennia marina from eastcoast region of Surabaya,it was known that the stemand leaves of the plant contained phenoliccompounds.Taking into account the existence of the waves andextreme weather conditions in the East Coast regionof Surabaya, it was hypothesized that the secondarymetabolite compounds produced by the plantswould be different. Based on that hypothesis it wasnecessary to do a research on Soneratia sp. plantlocated on the East Coast of Surabaya with the aimof exploring the content of secondary metabolitesfrom the stem of the plant.Methods that were used to accomplish that aimwere (1) preliminary test; (2) phytochemicalscreening; (3) GC-MS analysis and (4) antioxidanttest

Abstract

Heavy metals are substances that are harmful to human health. Heavy metals are usually found in the form of dissolved ions. One type of heavy metal is lead (Pb (II)). One way to reduce the Pb (II) content is by using the adsorption process using activated charcoal. Several materials from nature have been studied as materials of active charcoal for adsorption of heavy metal Pb (II), including oil palm shells, cassava peels, siwalan coir, and bamboo. Avicennia marina magrove plant is a species that is quite widely available in Surabaya. This study aimed to analyze the adsorption process of activated charcoal from mangrove Avicennia marina against heavy metal Pb (II). The method used includes three stages, namely (1) carbonization; (2) charcoal activation; (3) adsorption of Pb (II). From the research that has been done, it could be concluded that the activation process of charcoal into activated charcoal using ZnCl2 activator can open the pores on the surface of the charcoal, so that activated charcoal can adsorb Pb. The greater the initial concentration, the lower the adsorption% with the same amount of adsorbent. The process of Pb (II) isothermal adsorption by activated charcoal from the mangrove Avicennia marina, more closely follows the Langmuir isothermal adsorption model which had a value of R2 = 0.9968, while for the Freudlinch isotherm adsorption model had a value of R2 = 0.9474.

Abstract

Indonesia has the largest mangrove forest in the world. In addition, Indonesia is also a country with the largest number of mangrove species in the world. This creates a huge potential in the utilization of mangroves in many areas of life, one of them is in the health field. Where, the majority of the plants widely used in the health sector are land plants. Charcoal has been used in the field of health for thousands years. Charcoal generally utilized in the field of health in the form of activated charcoal. Activated charcoal or activated carbon is charcoal that has been through an activation process, chemical or physical. Activated charcoal can be made from any substance containing carbon. Given that wood is a renewable raw material, the use of wood as a material manufacture of activated charcoal is recommended. In this study, the material to be used in the manufacture of activated charcoal was wood from the mangrove plant Avicennia marina. The activation process used in this study was chemical activation using ZnCl2. This study included three stages: (1) carbonization; (2) activation of charcoal; (3) adsorption test of activated charcoal. The results showed that the higher the ratio of ZnCl2 mass / charcoal mass used in the activation process, the higher the adsorption capacity of activated charcoal produced. The highest % removal of CH3COOH was obtained at a ratio of ZnCl2 mass/charcoal mass of 2 which was 30.73%.
