Abstract

Batik Industry has been developed in Banyumas regency, Central JavaIndonesia. This industry produced liquid waste as the side of production process.The liquid waste decreased the water quality surrounds it. One of the pollutantwhich brought trough the liquid waste was heavy metal chromium (Cr) whichknown toxic to the organism in the water. Therefore, there should be preventionaction to minimize the bad impact of liquid waste. One of method which could beuse to prevent the water quality was by phytoremediation. There were three kindsof aquatic plant in this research; Eceng gondok (Eichornia crassipes), kayu apu(Pistia stratiotes) and ganggang (Hydrilla verticillata). The aim of using aquaticplant was to observe the ability of aquatic plant to decrease chromium level in thewater and decide which was the most effective. It was use completely randomizeddesign with 4 treatments and 6 repetitions, which will analyze by ANAVA andcontinued with LSD. The result showed that aquatic plant could be used asremediator agent to heavy metal Cr. Eceng gondok had 49.56%, kayu apu had33.61% and ganggang had 10.84% on decreasing Cr level in liquid waste of batikindustry. It can conclude that Eceng gondok was the most effectivephytoremediator agent on decreasing Cr level in liquid waste of batik industry.

Abstract

Indragiri Hilir mangrove forest is a type of one which is influenced by sea water tide, freshwater, soil texture, and salinity. The diversity of flora and fauna in the mangrove forest is relatively higher than that of many others in Indonesia. The potential vegetation is dominated by Bruguiera spp., Rhizophora spp., Avicennia spp., and Soneratia spp. This study was aimed to (1) determine biomass potential in Indragiri Hilir mangrove forest and (2) develop estimation model on the mangrove biomass with diameter of stem. The results showed that biomass potential of Rhizophora apiculata was 536.4 to 2,333.0 kg/tree, R. mucronata was 376.0 to 900.5 kg/tree, and Bruguiera spp. was 328.0 to 546.0 kg/tres. Estimation model on biomass of Bruguiera were 0.9450903501 D1.865827743 for stem biomass and 10.11259103 D 1.30096243 for total biomass, while those of R. apiculata were 0.2109981916 D 2.453342882 for stem biomass and  0.7574460068 D 2.232516567 for total biomass.
