The effects of initial pH, adsorbent dosage, contact time, and initial concentration were investigated in the batch adsorption mode. The optimum pH was found to be 5.5. Isotherm and kinetic data were modeled; the data fitted best to the Freundlich model, and, kinetically, the adsorption was of pseudo-second order as shown by the high R2 value of 0.9928 along with close agreement between the experimental qe (13.9 mg g ¡1) and calculated qe (14.24 mg g ¡1) values. The studied biomass material was found to be effectively used for removal of cadmium from contaminated mine wastewater.

Seagrass provides a habitat for diverse flora and fauna, spawning ground, nursery ground, raising ground, and feeding ground. Balanan Resort-Baluran National Park has many beaches, such as Kajang Beach, Si Banjir Beach, Kakapa Beach, and Serondo Beach. This study was aimed to determine species composition, seagrass dominated, and the diversity index of seagrass and substrate in Resort Balanan-Baluran National Park. This research was carried out in Kajang Beach, Sibanjir Beach, Kakapa Beach, and Sirondo Beach from August to September 2015 using belt transect method, each transect consists of 15 plots (19 transects = 285 plots) and using the frame of 1x1 m. This research found seven genera and ten species : Cymodoce (C rotundata and C. serrulata), Syringodium (S. isoelifolium), Thallassodendron (T. ciliatum), Enhalus (E. acoroides) , Halodule (H. univernis and H. pinifolia), Halophila (H. ovalis and H. decipiens), and Thalassia (T. hemprichii). The diversity index of seagrass bed was moderate [H'=1.90] in Balanan Resort. The substrate of seagrass bed was mud, gravel, sand, clay sand and rubble in Balanan Resort. The dominance index was near zero [C = 0.194], that means no dominant species.

Kegiatan tersebut menyebabkan tanah berpotensi tercemar oleh lindi, terutama jika TPA berada di daerah dengan curah hujan dan muka air tanahnya tinggi. Beberapa penelitian menunjukkan bahwa pencemaran lindi menjadi permasalahan yang umum terjadi di TPA di Indonesia. Hal itu sangat berbahaya karena secara umum, lindi sampah mengandung zat berbahaya seperti Cd, Zn, Cr, Hg, dan Ni (Freeze, 1979). Potensi pencemaran oleh lindi dapat diminimalkan dengan melakukan pengolahan yang tepat didasarkan atas kualitas dan kuantitas dari lindi di suatu TPA. Oleh karena itu, penelitian ini bertujuan untuk mengkarakterisasi lindi di sebuah TPA sebagai data primer untuk merancang teknologi pengolahan yang tepat. Karakter fisik-kimia adalah suhu, TDS, TSS, pH, Fe,Mn, Ba, Cu, Zn, Cr6+, Cr tot, Cd, Hg, Pb, Sn, As, Se, Ni, Co, CN, H2S, Fluoride, Cl2, NH3-N,...

This investigation studied seed storage at a low temperature, in vitro germination, and seedling development of H. cinnabarina in order to establish an optimized protocol for propagation, and thus assure species conservation. Seeds of different ages were incubated on Knudson C (KC), Murashige and Skoog, and Vacin and Went media with or without 1 μM of N6-benzyladenine (BA) and exposed to either 12 or 16 h of light (30 μmolm−2s−1 at 26±2°C). Seed surface sterilization was deleterious to 3-mo-old seeds and severely reduced the viability of the 4-mo-old seeds. More mature seeds were not affected by the sterilization procedure. In general, the germination of 4-, 5-, 6-, and 7-mo-old seeds increased when BA was added to the culture medium especially under 16 h of light. Germination rates were highest with 8- and 9-mo-old seeds, and application of BA failed to enhance germination rates further. Developmental studies revealed that this cytokinin reduced seed and protocorm mortality rates; however, protocorm development was negatively affected in its presence. Seedling development was more pronounced when KC medium with 16 h of light was used. Long-term seed storage at 4°C did not provide promising results. The protocol described in this study proved to be efficient and relevant to in vitro seed germination and initial development of H. cinnabarina, and thus will contribute to conservation of this orchid species.

Hence, it is necessary to remove the heavy metals before sea water enters the fish pond. The aim of this study was to know the growth, remediation ability, and the highest of removal efficiency of marine diatom Skeletonema costatum in the lead (Pb(II)) and cadmium (Cd(II)) solution. This study used 3 x 4 factorial design, i.e. concentrations of the cell inoculation (5000 cells mL-1; 10000 cells mL-1; and 15000 cells mL-1) and concentrations of Pb(II) and Cd(II) (0; 0.5; 1; and 2 ppm), replicated five times. During five day exposure time, the cell density was observed daily using a microscope (400X), while filtrate of media was analyzed using AAS. The result showed that S. costatum could grow in Pb(II) and Cd(II) at 2 ppm, and could remediate Pb(II) and Cd(II) at 2 ppm. The highest removal efficiency of marine diatom S. costatum in Pb(II) solution was 80.5% (5000 cells mL-1 at 2 ppm on the first day), and in...

The experiments in this work used batch mode adsorption. The parameters process studied were pH, adsorbent dosage and contact time. The values of pH studied were in the range of 2 to 7, the values of adsorbent dosage were in the range of 0.1 to 2 g while the contact time were in the range of 5 to 240 minutes. The results obtained showed that cadmium adsorption capacity was favored by increasing pH, dosage adsorbent and contact time. From the results obtained it can be concluded that algae was a promising adsorbent for cadmium sequestration from aqueous solution.

Bioremediation is an effective process for the removal and recovery of mercury (II) from seawater using organism as an agent of biological degradation. The aim of this study was to know the optimum contact time and concentrations of the Skeletonema costatum cell inoculation on the bioremediation in mercury (II) contaminated seawater. This study has used the concentrations of the cell inoculation (5000; 10000; and 15000 cells/mL), the mercury (II) (0; 0.5; 1; and 2 mg/L), the contact time (24, 48, 72, 96, and 120 hours), and its replicated five times. The maximum bioremediation capacity of mercury (II) was 2 mg/L at 15 000 cells/mL and contact time 96 hours, with bioremediation efficiency 86.83%. Diatom Skeletonema costatum was efficient at removing 2 mg/L mercury (II) 79.5% for 5 000 cells/L at 72 hours, 83.3 % for 10 000 cells/L at 72 hours and 85% for 15 000 cells/L at 72 hours. The optimum contact time and concentrations of...

Ten belt-transects were laid perpendicular to the shoreline, using standard methods. Vegetation structure was determined using data collected on plant species diversity, density, basal area, and the number of each species of mangroves. Shannon Wiener index to calculated diversity, evennes and Simpson to calculated dominance index. The results show there are 2 families and 6 mangrove species occurring in the study areas that is Rhizophoraceae (Rhizophora stylosa, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Ceriops tagal) and Araceae (Nypa fruticans). The highest importance value was R. apiculata (229.90...

Hence, it is necessary to remove the heavy metals before sea water enters the fish pond. The aim of this study was to know the growth, remediation ability, and the highest of removal efficiency of marine diatom Skeletonema costatum in the lead (Pb(II)) and cadmium (Cd(II)) solution. This study used 3 x 4 factorial design, i.e. concentrations of the cell inoculation (5000 cells mL-1; 10000 cells mL-1; and 15000 cells mL-1) and concentrations of Pb(II) and Cd(II) (0; 0.5; 1; and 2 ppm), replicated five times. During five day exposure time, the cell density was observed daily using a microscope (400X), while filtrate of media was analyzed using AAS. The result showed that S. costatum could grow in Pb(II) and Cd(II) at 2 ppm, and could remediate Pb(II) and Cd(II) at 2 ppm. The highest removal efficiency of marine diatom S. costatum in Pb(II) solution was 80.5% (5000 cells mL-1 at 2 ppm on the first day), and in...

The experiments in this work used batch mode adsorption. The parameters process studied were pH, adsorbent dosage and contact time. The values of pH studied were in the range of 2 to 7, the values of adsorbent dosage were in the range of 0.1 to 2 g while the contact time were in the range of 5 to 240 minutes. The results obtained showed that cadmium adsorption capacity was favored by increasing pH, dosage adsorbent and contact time. From the results obtained it can be concluded that algae was a promising adsorbent for cadmium sequestration from aqueous solution.
