Abstract

Beberapa aktivitas pabrik di sekitar kawasan Mangunharjo dapat mencemari lingkungan. Salah satu limbah yang menyebabkan pencemaran adalah logam kadmium (Cd). Keberadaan mangrove di kawasan pesisir menjadi sangat penting karena vegetasi mangrove mempunyai kemampuan mengakumulasi logam berat. Penelitian bertujuan untuk menganalisis kemampuan akumulasi Cd dalam akar dan daun mangrove Rhizophora mucronata di perairan laut dan lahan tambak Mangunharjo. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola factorial 2x2 dengan 3 kali ulangan. Faktor pertama lokasi : laut (L) dan tambak (T), faktor kedua organ : akar (A) dan daun (D). Data penelitian dianalisis secara statistik dengan metode ANOVA. Hasil penelitian menunjukkan bahwa kandungan Cd pada air di perairan laut dan lahan tambak berada di atas ambang batas, sedangkan kandungan Cd pada sedimen di perairan laut dan lahan tambak masih di bawah kisaran ambang batas. Akumulasi Cd organ akar dan daun di lokasi tambak lebih tinggi jika dibandingkan dengan organ akar dan daun di lokasi laut. Nilai Bio-Concentration Factor (BCF) pada akar di lokasi laut paling tinggi diikuti organ akar dan daun di lokasi tambak, sedangkan daun lokasi laut paling rendah.  Several factory activities around the Mangunharjo area can pollute the environment. One of the wastes that cause pollution is metal cadmium (Cd). The existence of mangroves in coastal areas is very important because mangrove vegetation has the ability to accumulate heavy metals. The aim of this study was to analyze the ability of Cd accumulation in the roots and leaves of Rhizophora mucronata mangroves in sea waters and Mangunharjo ponds. The study used a completely randomized design with a 2x2 factorial pattern with 3 replications. The first factor is location: sea (L) and ponds (T), the second factor is organs: roots (A) and leaves (D). The research data were statistically analyzed by the ANOVA method. The results showed that the Cd content in seawater and pond land was above the threshold, while the Cd content in sediment in sea waters and ponds was still below the threshold range. Cd accumulation of root and leaf organs in pond locations was higher than that of root and leaf organs in sea locations. The value of Bio-Concentration Factor (BCF) in roots at sea locations was the highest followed by root and lea/f organs in pond locations, while leaves at sea locations were the lowest.

Abstract

Aktivitas industri di perairan Mangunharjo menghasilkan limbah yang dapat menyebabkan pencemaran logam berat salah satunya yaitu kadmium (Cd). Mangrove Avicennia marina dapat mengabsorbsi Cd dari sedimen dan air melalui akar kemudian di translokasi ke organ lain seperti daun dan akar sehingga berpotensi sebagai fitoremidiasi. Penelitian ini bertujuan untuk menganalisis kemampuan akumulasi Cd pada akar dan daun mangrove Avicennia marina di perairan laut dan tambak Mangunharjo. Penelitian ini menggunakan RAL dengan 2 faktor yaitu lokasi (tambak dan laut) dan organ (daun dan akar) masing-masing perlakuan dengan 3 ulangan. Analisis kandungan Cd menggunakan metode AAS (Atomic Absorption Spechtophotometry), data diuji dengan ANOVA, dilanjutkan dengan DMRT pada taraf uji 5 %. Hasil penelitian menunjukkan bahwa di tambak kadar Cd pada sedimen yaitu 1.0897 ppm dan pada air 0.0123 ppm, sedangkan di laut kadar Cd pada sedimen yaitu 0.1193 ppm dan pada air 0.0163 ppm. Faktor organ mangrove dan lokasi menujukkan interaksi terhadap kadar Cd dan nilai BCF. Kadar Cd tertinggi terdapat pada organ daun di tambak (0.2269 ppm) dan nilai terendah terdapat pada organ daun di laut (0.0200 ppm). Nilai BCF tertinggi terdapat pada organ akar di laut (0.5133) dan yang paling rendah adalah organ daun di laut (0.0567). Industrial activities in the waters of Mangunharjo produce waste that can cause heavy metal pollution, one of which is cadmium (Cd). Avicennia marina mangroves can absorb Cd from sediment and water through the roots and then translocated to other organs such as leaves and roots so that it has the potential as phytoremediation. This study aimed to analyze the ability of Cd accumulation in the roots and leaves of Avicennia marina mangroves in Ponds and Mangunharjo Seas. This study used RAL with 2 factors, namely location (ponds and sea) and organs (leaves and roots) each treatment with 3 replications. Analysis of Cd content using AAS (Atomic Absorption Spechtophotometry) method, data was tested by ANOVA, followed by DMRT at the 5% test level. The results showed that in ponds the Cd content in sediment was 1.0897 ppm and in water was 0.0123 ppm, while at sea the Cd level in sediment was 0.1193 ppm and in water was 0.0163 ppm. Mangrove organ factors and location showed an interaction with Cd levels and BCF values. The highest Cd levels were found in leaf organs in ponds (0.2269 ppm) and the lowest values were found in leaf organs in the sea (0.0200 ppm). The highest BCF value was found in root organs in the sea (0.5133) and the lowest was in leaf organs in the sea (0.0567).

Abstract

Mangrove plants are sensitive to environment condition. This research aimed to analyze the linkages of mangrove growth and environment dynamics and to estimate the growth of mangrove along with the environment dynamics. The research was conducted through the field experiment by the plantation of A. marina in silvofishery pond canals. Data collection was conducted for 18 months with 3 months observation interval. The environment variables observed including temperature, salinity, turbidity, pH, dissolved oxygen, TSS, sediment organic matter, nitrogen and phosphorus, and the growth of mangrove seedling. Analysis was conducted through regression and modelling with Powersim software. The result showed that the height growth was affected by dissolved oxygen, temperature, salinity, turbidity and pH, while the diameter growth was affected by TSS concentration. Inversely, the growth of mangrove also had a significant effect on temperature, change of organic matter and nutrient sediment concentration. Simulation showed that the height and diameter growth rates of A. marina seedling were dynamically changed among periods. Simulated seedling growth for one year forecast resulted in the rate of 0.115024 to 0.282294 cm/day for height and 0.001287 to 0.006031 cm/day for diameter. The simulation also indicated the continuous accumulation of organic matter and nitrogen over time. This research concluded that under limited environment dynamic, the growth of mangrove could be estimated. This model is a novelty in ecological studies. This research might initiates the more advanced ecological studies. Systematic estimation of ecosystem behaviour could be applied to formulate the best management practices, particularly in the silvofishery activities.

Abstract

Environmental dynamic in the coastal area is suggested to affect the metabolite concentration in mangrove plants. This research aimed to study the concentration of total phenol in A. marina leaf and to analyze the effect of environmental parameters on total phenol content dynamics. Environmental parameters studied in this research was temperature, pH, DO, and salinity, as well as N, P, and C sediment content. Data analysis was carried out through multiple regression of natural logarithm transformed data. Laboratory analysis resulted the value of total phenol content in A. marina leaf ranging from 0.88 – 1.62% with the average concentration of 1.28 ± 0.28%. Regression analysis resulted the significant effect of temperature, DO, and sediment content P and C expressed in the formula: ln(TP) = 31.229 – 7.224ln(T) – 0.067ln(DO) – 1.054ln(P) – 1.241ln(C). The research implicated that the increasing value of those factors was approaching the suitable condition for A. marina. Thus, instead of increasing the phenol concentration, the parameters negatively effect the secondary metabolite. The result showed that increasing temperature, DO, and content of P and C reduced the stress in A. marina and reduce total phenol content. This suggests that low temperature, DO, P and C concentration provides more potential of phenolic products from A. marina.

Abstract

Water Jasmine [Echinodorus palaefolius (Ness Mart.) J.F. Macbr.] is an aesthetic plant, that can purify wastewater containing high metals through phytoremediation. By using constructed wetlands system E.palaefolius was used to accumulate Fe (Iron) in leachate. Leachate comes from garbage that was piled up and decomposeds. The purpose of this research was to examine the ability of E. palaefolius plants to accumulate Fe in leachate. This study, used a completely randomized experimental design (CRD). The treatment variation were contact time of plants with leachate consisting of 0,7,14, and 21 day after planting. The results showed that Fe accumulated at the root was 10.86 mg/kg with the highest absorption rate occurring at 7 DAP with 1.56 mg/kg/day and BCF of 49.5 ppm. Fe accumulation on the stem was 571 mg/kg, the highest absorption rate at 14 DAP 63.71 mg/kg/day and BCF 3144.54 ppm. The accumulation of Fe in leaves was 696 mg/kg, the highest absorption rate was at 7 DAP with 104 mg/kg/day and BCF value of 3279.28 ppm. The results shows that the duration of contact affects the ability of E. palaefolius in accumulating Fe and improving the quality of leachate.
