Abstract

This research aims to to study the ability of awar-awar plants ((Ficus Septica Burm. F)) to accumulate heavy metals. Awar-awar are grown in glass reactors and treated with 10 ppm mercury solution wich one, two, and three weeks in time variations. The analysis using CV-AAS showed that the total absorption of mercury heavy metals by awar-awar plants in reactors I, II and III was 81.7%, 34.6% and 85.4% respectively. When the phytoremediation process takes place the plant shows no symptoms of damage or even death even though it has accumulated more than 50% of mercury from the growing media. The BCF value of awar-awar plants in reactor I was 2.79 reactor II was 0.53 and reactor III was 0.55. While the TF values ​​in reactors I, II and III were 0.04; 1.13 and 0.97. The calculation results of BCF and TF values ​​show that Awar-awar plants (Ficus Septica Burm. F) can accumulate heavy metals of mercury so it is recommended to be used as a phytoremediation agent in mercury-contaminated soils.

Abstract

This study examines the accumulation of metallic mercury by several types of plants in the traditional gold processing area in the village of Gogore, Buru district. The plants that were sampled in this study were guava, lempuyang gajah, and harendong bulu. These three plant species were chosen because they dominate the vegetation in the gold processing area. The analysis results showed that the lempuyang gajah was the plant that accumulated the highest mercury metal, namely in the roots of 16.79 ppm and the leaves of 15.03 ppm. Guava plants accumulated metal mercury in the roots and leaves of 11.73 ppm and 9.90 ppm, respectively. Meanwhile, harendong plants accumulated mercury in the roots and leaves of 2.59 ppm and 10.39 ppm, respectively. The BCF values ​​of guava, lempuyang gajah, and harendong bulu plants were 1.58, 0.41, and 0.39, respectively. Meanwhile, the TF values ​​of the three plants were 0.84, 0.89, and 4.01, respectively. From these results, it can be concluded that the three plants can accumulate mercury in high enough concentrations, so these three types of plants are categorized as hyper tolerant plants and accumulators.

Abstract

This study aims to determine the composition of the oxide, the characteristics of palm shell and coir, and silica gel synthesized. The oxide composition, crystallinity, palm shell and coir ash functional groups were analyzed using XRF, XRD, and FTIR. Analysis of the functional groups and crystallinity using FT-IR and XRD. The results showed the composition of SiO2 in palm shell and coir ash was 76%, and SiO2 in the form of quartz and cristobalite was more dominant than amorphous SiO2. The synthesis success was indicated by the appearance of peaks with low intensity, not sharp, and resembling bumps on the synthesized silica gel diffractogram, which is an amorphous SiO2 characteristic. This result is confirmed by FT-IR, where absorption at wave number 455 cm-1 is a Si-O-Si bending vibration, 783 cm-1 is a stretching vibration of Si-O symmetry of Si-O-Si, 3454.51 cm-1, and 3568 cm-1 with fairly high intensity are characteristic of the -OH group from Si-OH. The wide and sharp absorption at 1083.99 cm-1 is a stretching vibration of the Si-O symmetry of Si-O-Si, 1625.99 cm-1 is -OH vibration of water molecule, 798.53 cm-1 is Si-O stretching vibration of Si-O-Si and absorption of 462.92 cm-1 indicates bending vibration of Si-O-Si.

Abstract

This research aims to study the extent of bioaccumulation of the heavy metal Pb by mangrove plants (Rhizopora apiculata) in the waters of Poka Village, Ambon Bay. Mangrove plants were chosen because they can naturally accumulate heavy metals around their roots. In this study, sediment grains were measured using a Sieve Shaker, the content of Pb metal in sediment and parts of mangrove plants was determined using AAS, while the bioaccumulation value of Lead metal (Pb) by mangrove plants was calculated using the BCF and TF formulas. The results showed that the particle size in gravel ranged between 0.00-0.13%, sand 20.44-66.35%, and mud 33.65-79.56%. Lead (Pb) levels in Poka Village waters in sediment ranged from 10,925-16,925 mg/kg, roots ranged from 0.5-21.35 mg/kg, and leaves ranged from 0-4,675 mg/kg. Meanwhile, the BCF value at sampling point 1 = 0.03, sampling point 2 = 1.40 and sampling point 3 = 0.56, the TF value at sampling point 1 = 7.8, sampling point 2 = 0.03 and sampling point 3 = 0.09. This shows that mangrove plants function as phytoextraction and can be used as phytoremediation agents to accumulate the heavy metal lead (Pd) from waters.

Abstract

This research aims to study the level of heavy metal Pb bioaccumulation by sea grass (Enhalus acoroides) in the waters of Tulehu Village, Central Maluku Regency, where the type of particles and Pb content in sediment, roots and leaves are important variables for studying the accumulation and translocation of Pb metal ions by sea grass. Lead (Pb) content in sediment, roots and leaves of sea grass was measured using an atomic absorption spectrophotometer. The ability to accumulate and translocate lead (Pb) in sea grass (Enhalus acoroides) is known from the BCF (bioconcentration factor) and TF (translocation factor) values. The results of the study showed that the type of sediment particle grains at point I was 2.92% gravel, 86.67% sand, 26.67% mud, the size of sediment grains at point II was 16.67% gravel, 82.94% sand, 2.35% mud, and the size of sediment grains at point III was 19.77%, 64.58% sand, 1.04% mud. The Pb metal content produced at point I ranged from 4.80 mg/kg, point II ranged from 4.85 mg/kg and point III ranged from 4.44 mg/kg. The BCF values obtained at points I, II, and III were respectively 0.55; 2.20; 2.12.
