The heavy metals that polluted sea water can end up polluting fish pond too. 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 Cd(II) solution was 80% (15000 cells mL-1 at 0.5 ppm on the fifth day).

Ecotourism development program at Bama beaches area require baseline data of mangrove structure at Bama Resort and in the past two decades has been lost about 35% area of mangrove forest in Indonesia and in the worldThe aims of this study was to find structure, composition, distribution and zonation patterns of mangroves at Bama Resort Baluran Nasional Park. 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%) for trees, R. apiculata (148.69%) for the sapling, and R. apiculata (244.83%) for the seedling. The diversity (H) and dominance index (C) values were moderate (1.79) and 0.521. The most dominant species was R. apiculata (C=0.487). The mangrove zonation pattern from coastline to the mainland was R. stylosa, R. mucronata, and R. apiculata, in the outer zone, respectively (zone directly adjacent to the sea); B. gymnorrhiza and C. tagal in the middle zone; and N. fruticans in the zone that adjacent to the mainland. The present study will aid in the conduct and preservation planning of mangrove forest especially at Bama coast and generally in the coastal areas of Indonesia.

Natural wetlands are the natural habitat of waterbirds, but it is very diffi cult to fi nd an unspoiled wetlands without human interventioncurently. East coast of Surabaya is wetlands area in Surabaya that most of the region have change into fi shpond and residental. Theaims of this reasearch are to determine the community structure of waterbirds in each type of wetland utilization and to determine ifthe different type of wetland utilization infl uence the community structure of waterbirds in East Coast of Surabaya. Data were collectedduring August 2012 to January 2013 with point count method. Six sampling plots have been selected. Six sampling plots representingfour types of use of wetlands, which are bozem, the former fi shpond, fi shpond with vegetation, and fi shponds without vegetation (fi shpond1, fi shpond 2 and fi shpond 3). In bozem recorded 19 species of waterbirds (1107 individual), dominated by shorebirds, with a diversityindex (H') 1.86, and evenness index (J') 0.63. In former fi shpond recorded 7 species of water birds (168 individual), dominated by railsand moorhen, with H’ = 1.12 and J’ = 0.57. In fi shpond with vegetation recorded 12 species of water birds (137 individual), dominatedby large wader, with H’ = 1.85 and J’ = 0.74. In fi shpond 1 recorded 18 species of water birds (299 individual), dominated by terns,with H’ = 1.96 and J’ = 0.68. In fi shpond 2 recorded 9 species of water birds (70 individual), dominated by terns, with H’ = 1.73 andJ’ = 0.79. In fi shpond 3 recorded 10 species of water birds (83 individual), dominated by terns, with H’ = 1.84 and J’ = 0.80. Chi-squaretest showed that X2 count is greater than X2 table with α < 0.05, which indicates that there is a signifi cant difference of the numberof individuals of each species and the number of individual of each water birds’ group for each type of use of wetlands, so it can beconcluded that different types of use of wetlands affect water bird community structure in the East Coast Surabaya.

The objective of this research was to prove that the administration of radish tuber extract (Rhapanus sativus L) to female mice (Mus musculus) might increase blood prolactin level. This was an experimental research using complete randomized design by involving three treatment groups and three control group, each with five replications. Materials consisted of radish tuber extract and 30 female mice of 8 weeks old divided into 6 groups, i.e., control groups of C1, C2, and C3, and treatment groups of T1, T2, and T3. C1, C2, and C3 groups were given water of 1 × 0.5 cc/day per oral, 2 × 0.5 cc/day, and 3 × 0.5 cc/day respectively. Treatment groups of T1, T2, and T3 were given radish tuber extract of respectively 1 × 0.5 cc/day per oral, 2 × 0.5 cc/day, and 1 × 0.5 cc/day. Treatment was carried out for 21 days. Blood was subsequently taken from those rats for blood prolactin level. Data were analyzed using Anove test. If the results indicated significant difference of 95% (p = 0.05), the analysis was continued with LSD. The conclusions of this experiment is the administration of radish tuber extract per oral may result in the increase of blood prolactin level.

Industrial wastewater often contains heavy metals such as Pb(II) and Cu(II) that pose significant environmental and health risks. This study investigates the utilization of Black Soldier Fly (BSF) (Hermetia illucens) pupal shells as an adsorbent material for the removal of Pb(II) and Cu(II) ions from aqueous solutions. BSF pupal shells were chosen due to their high availability, rapid life cycle, and chitin-rich composition, making them suitable for heavy metal adsorption. The preparation process included washing, drying, grinding, and activation with 1 M NaOH solution. Characterization of the adsorbent was performed before and after adsorption using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (SEM-EDX). Adsorption experiments were conducted to examine the effects of pH, contact time, and initial ion concentration. The optimum pH for adsorption was found to be 5.5, achieving removal efficiencies of 95.5% for Pb(II) and 71.81% for Cu(II). The optimum contact times were 180 minutes for Pb(II) and 240 minutes for Cu(II). Kinetic analysis demonstrated that the adsorption process followed a pseudo-second-order model. Adsorption isotherm studies indicated that the Langmuir model provided a better fit (R² = 0.99 for Pb(II) and 0.98 for Cu(II)) compared to the Freundlich model (R² = 0.90 for Pb(II) and 0.77 for Cu(II)). These results demonstrate that BSF pupal shells are a promising, cost-effective, and environmentally friendly material for industrial wastewater treatment applications
