Studi absorpsi metal tosik tembaga (copper) oleh Gracilaria sp. telah dilakukan. Tujuan dari studi ini adalah meneliti kemungkinan kemampuan vegetasi akuatik yang akan digunakan sebagai biofilter. Pada kegiatan budidaya air payau di Indonesia, logam tembaga sering digunakan sebagai desinfektan pemusnah predator pada saat tahapan persiapan kolam/tambak. Namun di lain pihak tembaga juga memiliki potensi toksisitas yang tinggi terhadap lingkungan. Studi ini dilakukan secara laboratoris, dengan melakukan pemaparan rumput laut Gracilaria sp. pada tiga perlakuan konsentrasi tembaga yang berbeda (K1: kontrol; K2: 0,5 ppm; dan K3:1 ppm) selama empat perbedaan waktu pemaparan (M1: 1 minggu; M2: 2 minggu; M3: 3 minggu; dan M4: 4 minggu). Analisis kandungan tembaga pada Gracilaria sp. dilakukan pada setiap minggu. Hasil penelitian ini menunjukkan bahwa Gracilaria sp. mampu menyerap tembaga yang terlarut dalam air laut. Penyerapantembaga meningkat secara sangat nyata sejalan dengan peningkatan perlakuan konsentrasi dan lama waktu dedah. Konsentrasi tembaga yang diserap pada K2 (0,5 ppm Cu) adalah, masing-masing, 12,745 ppm(setelah pemaparan 1 minggu), 27,604 ppm (setelah pemaparan 2 minggu), 29,890 ppm (setelah pemaparan 3 minggu), dan 30,215 ppm (setelah pemaparan 4 minggu). Sementara itu, konsentrasi tembaga setelah pemaparan Gracilaria sp. pada K3 (1 ppm Cu) masing-masing adalah 31,980 ppm (setelah pemaparan 1 minggu), 50,564 ppm (setelah pemaparan 2 minggu), 53,884 ppm (setelah pemaparan 3 minggu), dan54,486 ppm (setelah pemaparan 4 minggu).Kata kunci: Gracilaria sp., tembaga, logam toksik, absorpsi/penyerapan.Absorption of toxic metal (copper ) by Gracilaria sp. had been studied. The aim of the study reported in this paper was to investigate the possibility of Gracilaria sp. as a biofilter. In brackish water pond culture in Indonesia, copper is usually used as the predator eradicator in pond preparation. But in other hand, copper has potentially high toxicity to the aquatic environment. The study was conducted in the laboratory, by exposing seaweed Gracilaria sp. to three different concentrations of copper (K1: control; K2: 0,5 ppm; and K3: 1 ppm), during four different exposure times (M1: 1 week; M2: 2 weeks; M3: 3 weeks; and M4: 4 weeks). Analyses of copper metal accumulated by Gracilaria sp. were done every week. The results of present works revealed that Gracilaria sp. is able to absorb copper metal dissolved in seawater. Absorption of copper increase significantly by increasing of copper concentration and exposure duration. The concentrations of copper absorbed in K2 (0,5 ppm Cu) are, respectively, 12,745 ppm (after 1 week exposure), 27,604 ppm (after 2 weeks exposure), 29,890 ppm (after 3 weeks exposure), and 30,215 ppm (after 4 weeks exposure). Meanwhile, the concentrations of copper after exposure Gracilaria sp. to K3 (1 ppm Cu) are 31,980 ppm (after 1 week exposure), 50,564 ppm (after 2 weeks exposure), 53,884 ppm (after 3 weeks exposure), and 54,486 ppm (after 4 weeks exposure), respectively.Key words: Gracilaria sp., copper, toxic metal, absorption.

Polyethylene is a plastic material that was globally produced and is well known as a non-degradable pollutant product. Plastic pollution, primarily microplastics, have been distributed to coral reef ecosystems, where these areas are ecosystems with high productivity. Karimunjawa National Park in Indonesia is one of the protected areas for coral reef ecosystem habitat in Central Java, threatened by microplastic contamination. Recent studies have shown that coral-associated bacteria have an adequate ability to degrade marine pollutant materials. No one has reported that the use of indigenous coral-associated bacteria has the potential for microplastic biodegradation, especially low-density polyethylene microplastic materials. Hence, the objective of this study was to find the potential of microplastic biodegradation agents derived from coral-associated bacteria in Karimunjawa National Park area. Various coral life-forms were isolated in July 2020 from conservation areas and areas with anthropogenic influences. Bacterial isolates were screened using tributyrin and polycaprolactone as substrates to reveal potential microplastic degradation enzymes. The total isolation results obtained 92 bacterial isolates, and then from the result of enzyme screening, there were 7 active bacteria and only 1 bacteria that potential to degrade polyethylene. LBC 1 showed that strain could degrade by 2.25±0.0684 % low-density polyethylene microplastic pellet by incubating bacterial growth until the stationary phase. Identification of LBC 1 strain was carried out by extracting DNA and bacterial 16S rRNA sequences. Bacterial gene identification refers to Bacillus paramycoides with a similarity level in the National Center Biotechnology Information database of 99.44%. These results prove that hard coral association bacteria can degrade low-density polyethylene microplastics.

Kemajuan teknologi budidaya udang di Indonesia semakin pesat, seiring dengan berkembangnya budidaya Udang Putih Vaname (Litopenaus vannamei), sebagai komoditas ekonomis di tambak selain udang windu dan bandeng. Budidaya intensif Udang Vaname dicirikan dengan padat penebaran benih tinggi dan penggunaan pakan tambahan. Manajemen pakan yang kurang baik, berakibat pada timbulnya sisa pakan, secara perlahan-lahan akan meningkatkan kadar bahan pencemar dan menurunkan kualitas air tambak. Upaya yang dikembangkan untuk mengurangi masukan nutrien dari pakan selama budidaya udang vaname intensif adalah metode panen parsial, yaitu melakukan pemanenan udang secara bertahap (parsial) saat proses budidaya berlangsung. Tujuan dari penelitian ini adalah untuk mengevaluasi fluktuasi amoniak, menganalisa sumbangan beban cemaran amoniak ke lingkungan serta mengkaji kelayakan usaha budidaya udang vaname intensif dengan teknik panen parsial dan panen total. Panen parsial dilaksanakan umur 65 hari pada petak 2B, sedangkan panen total petak 2A dan 2B umur 80 hari pemeliharaan. Hasil yang diperoleh kandungan amoniak di akhir periode pemeliharaan petak 2A (panen total) dan petak 2B (panen parsial) adalah 0,120 mg/l dan 0,050 mg/l dengan nilai indeks kualitas air Prakash yang sama yaitu 51,11 kriteria kualitas air sedang. Sumbangan beban cemaran amoniak terhadap lingkungan petak 2A sebesar 7,667 kg/ha/th, petak 2B sebesar 3,164 kg/ha/th. Penilaian kelayakan ekonomi dari biomassa Udang Vaname yang dipanen secara total dan parsial. Hasil perhitungan teknik panen total nilai NPV Rp 88.448.362: IRR 27,09 ; B/C 2,11, teknik panen parsial NPV Rp 426.601.399 ; IRR 69,02: B/C 2,30. Kedua teknik panen mencerminkan usaha layak untuk dilanjutkan. Teknik panen parsial. mampu meminalkan sumbangan beban cemaran ke lingkungan serta memberikan keuntungan usaha lebih besar Rp 9.063.000/siklus/petak dibandingkan teknik panen total. Perlu adanya upaya pengolahan buangan air limbah di akhir pemeliharaan sebelum dibuang ke perairan umum agar memenuhi syarat baku mutu effluent. Technological development of shrimp farming in Indonesia is growing rapidly, along with the development of white shrimp(Litopenaus vannamei) aquaculture, which is an economically viable commodity in pond culture besides tiger prawn and milkfish. Vanamei intensive shrimp aquaculture is characterized by a high stocking density of seeds and the use of additional feed. Poor feed management will result in the increase of food residue and gradually increases the levels of pollutants that degrade the water quality. Efforts to reduce nutrient inputs of feed for shrimp farming is partial harvesting method by harvesting shrimp in stages (partial) during the period of culture. The purpose of this study was to evaluate the fluctuation of ammonia, analyzing environmental contaminant load and study the feasibility of intensive shrimp farming of vanamei with partial harvesting techniques and the total harvest. Partial harvest was held at the age of 65 days for plots 2B, while the total harvest was done at plots 2A and 2B at 80 days. The results of ammonia concentration at the end of the culture period 2A plots (total harvest) and plots 2B (partial harvest) was 0.120 mg / l and 0.050 mg / l respectively, with similar Prakash water quality index of 51.11. Ammonia contamination load in plots 2A was 7,667 kg / ha/years, and plots 2B was 3,164 kg / ha/years. Results of the NPV value of total harvest was Rp 88,448,362: IRR 27.09; B / C of 2.11 whereas for partial harvesting techniques NPV Rp 426 601 399; IRR 69.02: B / C 2.30. Partial method techniques of vanamei harvest can be minimalizing contaminant load in environmental and was more feasible because it provides greater profit of Rp. 9.063 million / cycle / plot. Efforts are required to discharge wastewater treatment at the end of the culture period before being released into the surrounding environment in order to meet the required effluent quality standarts.

Biosorption Capacity and Growth of Seaweed Gracilaria sp. In Media Containing Heavy Metal Cadmium (Cd) Contamination of coastal and marine waters by heavy metals in significant concentrations will threaten the lives of biota inhabitant. One of the dangerous heavy metals due to its potential toxicity is cadmium (Cd). The purpose of this study was to find out: biosorption ability of Gracilaria sp. against Cd in seawater media, the effect of exposure time on Cd content absorbed by Gracilaria sp., and growth of Gracilaria sp. in Cd-contaminated media with different concentrations. This study used a laboratory experimental method, by exposing Gracilaria sp. to three different concentration treatments and one control treatment (A: Control; B: 0.1 mg/L; C: 1 mg/L; and D: 10 mg/L) for 4 weeks. Observation of biosorption ability and growth of Gracilaria sp. was done every week. The results of the research on biosorption ability showed that Gracilaria sp. was able to absorb Cd dissolved in seawater. The concentrations of Cd absorbed by Gracilaria sp., respectively in treatment B were 1.81 mg/kg (first week), 2.33 mg/kg (second week), 4.51 mg/kg (3rd week), and 1.47 mg/kg (4th week); in treatment C were 8.07 mg/kg (first week), 11.67 mg/kg (second week), 9.86 mg/kg (3rd week), and 8.67 mg/kg (4th week); and in treatment D were 52.59 mg/kg (first week), 56.66 mg/kg (second week), 78.01 mg/kg (3rd week), and 87.67 mg/kg (4th week). It is concluded that Gracilaria sp was capable of absorbing cadmium dissolved in seawater. However, the growth of Gracilaria sp. (absolute and specific growth rate) showed a decrease in biomass weight due to exposure to Cd-contaminated media, making Gracilaria sp. was not as a good species to be used as a Cd-metal hyperaccumulator. Kontaminasi perairan pesisir dan laut oleh logam berat dalam konsentrasi yang signifikan akan mengancam bagi kehidupan biota yang ada di dalamnya. Salah satu logam berat yang berbahaya karena sifat toksisitasnya adalah Kadmium (Cd). Tujuan dari penelitian ini untuk mengetahui: 1) kemampuan biosorpsi rumput laut Gracilaria sp. terhadap logam berat Cd dalam media air laut dengan konsentrasi yang berbeda, 2) mengetahui pengaruh perbedaan waktu pendedahan (exposure time) terhadap kandungan logam Cd terabsorpsi oleh Gracilaria sp., dan 3) mengetahui pertumbuhan Gracilaria sp. pada media terkontaminasi logam berat Cd dengan konsentrasi yang berbeda. Penelitian menggunakan metode eksperimental laboratoris, dengan melakukan pemaparan rumput laut Gracilaria sp. pada tiga perlakuan konsentrasi yang berbeda dan satu perlakuan kontrol (A: Kontrol; B: 0,1 mg/L; C; 1 mg/L; dan D 10 mg/L) selama 4 minggu masa pemeliharaan. Pengamatan kemampuan bioabsorpsi dan pertumbuhan Gracilaria sp. dilakukan setiap minggu. Hasil penelitian kemampuan bioabsorpsi menunjukkan bahwa Gracilaria sp. mampu menyerap logam Cd yang terlarut dalam air laut. Konsentrasi logam berat Cd yang diserap Gracilaria sp. pada perlakuan B = 1,81 mg/kg (minggu ke-1), 2,33 mg/kg (minggu ke-2), 4,51 mg/kg (minggu ke-3), 1,47 mg/kg (minggu ke-4); Perlakuan C = 8,07 mg/kg (minggu ke-1), 11,67 mg/kg (minggu ke-2), 9,86 mg/kg (minggu ke-3), dan 8,67 mg/kg (minggu ke-4); Perlakuan D = 52,59 mg/kg (minggu ke-1), 56,66 mg/kg (minggu ke-2), 78,01 mg/kg (minggu ke-3), dan 87,67 mg/kg (minggu ke-4). Dapat disimpulkan bahwa Gracilaria sp mampu menyerap Cd terlarut dalam air laut. Namun demikian, pertumbuhan Gracilaria sp. (pertumbuhan mutlak dan laju pertumbuhan spesifik) mengalami penurunan berat biomassa akibat pemaparan pada media mengandung logam Cd, sehingga menjadikan spesies Gracilaria sp. bukan sebagai spesies hiperakumulator yang baik untuk logam Cd.

Chitosan is able to be one solution to reducing the pollution of heavy metals in waters, as capable of binding of heavy metal ions by utilizing the amine and hydroxyl groups on chitosan. This research aims to know the adsorption ability of chitosan against heavy metals lead (Pb). Chitosan is made from the waste of a small crab attaching shells were taken from the village of Betahwalang, Demak. The method used is the method with the demineralisasi using 1 N HCl for 1 hour, deproteinasi with 3.5% NaOH for 1 h, and deasetilasi using NaOH 50% for 2 hours. FTIR analysis of the results showed the degree of Deasetilasi Chitosan of 80.30% with 36.84% yield. Solution of Pb of Pb (CH3COO)2 at a concentration of 10 mg/L is used as pollutants, and the concentration of chitosan used in adsorption process i.e. 1, 2, 4, and 8%. Stirring on the process of adsorption using a magnetic stirrer with a speed of 200 rpm for 30 minutes. The metal content of Pb in the chitosan is then analyzed using AAS (Atomic Absorption Spectrophotometric). The results showed that chitosan obtained from shell small crab attaching has the potential as a bioadsorben metals Pb, the concentration of chitosan 1, 2, 4, 8% & each have an absorbance of 8.31; 35.62; 45.24 & 57.74%.Kitosan mampu menjadi salah satu solusi mengurangi pencemaran logam berat di perairan, karena mampu mengikat ion-ion logam berat dengan memanfaatkan gugus hidroksil dan amina yang terdapat pada chitosan. Penelitian ini bertujuan untuk mengetahui kemampuan adsorpsi chitosan terhadap logam berat Timbal (Pb). Chitosan dibuat dari limbah cangkang rajungan yang diambil dari desa Betahwalang, Demak. Metode yang digunakan adalah metode kimia dengan demineralisasi menggunakan HCl 1 N selama 1 jam, deproteinasi dengan NaOH 3,5 % selama 1 jam, dan deasetilasi menggunakan NaOH 50 % selama 2 jam. Hasil analisis FTIR menunjukkan Derajat Deasetilasi kitosan sebesar 80,30 % dengan rendemen 36,84 %. Larutan Pb dari Pb(CH3COO)2 pada konsentrasi 10 mg/L digunakan sebagai polutan, dan konsentrasi chitosan yang digunakan pada proses adsorpsi yaitu 1, 2, 4, dan 8 %. Pengadukan pada proses adsorpsi menggunakan magnetic stirrer dengan kecepatan 200 rpm selama 30 menit. Kandungan logam Pb yang ada di dalam chitosan kemudian dianalisis dengan menggunakan metode AAS (Atomic Absorption Spectrophotometric). Hasil penelitian menunjukkan bahwa chitosan yang didapatkan dari cangkang rajungan mempunyai potensi sebagai bioadsorben logam Pb, konsentrasi chitosan 1, 2, 4, & 8 % masing-masing memiliki daya serap sebesar 8,31; 35,62 ; 45,24 & 57,74 %.
