Abstract

Abstract. One of the regions in Surabaya which has accumulated the largest pollution levels was the region of Wonorejo. Wonorejo is an area that is used as a mangrove conservation. But,Pb and Cu are heavy metals that have been detected in high concentration in this region. Avicennia albahas been known to have the ability to absorb heavy metals so that mangrove can be used us phytoremediation agent. The purposes of this research were to analyze the concentration of heavy metals (Pb and Cu) in sediments, roots and leaves of Avicennia alba;  to understand the potential of Avicennia albaas an agent of phytoremediation. The result showed that Cu concentration was higher than Pb concentration in sediment, roots and leaves. The concentrations  of Cu were4.13 ppm - 36.95 ppm and Pb between 3.28 ppm - 23.79 ppm. Based on bioconcentration factor (BCF) Avicennia alba was categorize as excluder (BCF1)  of both heavy metals, but concentration oftranslocation factor (TF) of Pb was categorized phytoexstraction (TF1) and Cu was categorized phytostabilization (TF1). The result of the BCF and TF showed that Avicennia alba can absorb heavy metals (Pb and Cu) from the environment, however the mobility of the heavy metals in the mangrove will experience different phytoremediation mechanisms (phytostabilization for Cu; phytoexstractionfor Pb).Keywords: Avicennia alba, Phytoremediation, Factor Bioconcentration, Factor Translocation, Heavy Metal (Pb and Cu) Abstrak. Salah satu kawasan di Kota Surabaya yang mempunyai tingkat akumulasi pencemaran terbesar adalah wilayah Wonorejo. Wonorejo merupakan wilayah yang dimanfaatkan sebagai daerah konservasi mangrove. Namun, Pb dan Cu merupakan logam berat yang terdeteksi dalam jumlah yang tinggi pada wilayah ini.Avicennia alba mempunyai kemampuan menyerap logam berat sehingga mangrove dapat dijadikan sebagai agen fitoremediasi. Penelitian ini bertujuan untuk mengetahui kandungan Pb dan Cu yang terdapat dalam sedimen, akar dan daun Avicennia alba; untuk mengetahui potensi Avicennia albasebagai agen fitoremediasi logam berat Pb dan Cu. Distribusi Pb dan Cu pada sedimen, akar dan daun menunjukkan Cu lebih tinggi dibandingkan Pb yang berkisar 4.13 ppm - 36.95 ppm untuk Cu dan 3.28 ppm - 23.79 ppm untuk Pb. Berdasarkan nilai faktor biokonsentrasi (BCF) maka Avicennia albaterkategori bersifat excluder (BCF1) untuk kedua logam berat, namun berdasarkan faktor translokasi (TF) Avicennia alba bersifat fitoekstraksi (TF1) terhadap Pb dan fitostabilisasi (TF1) terhadap Cu. Berdasarkan hasil perhitungan BCF dan TF maka dapat disimpulkan bahwa Avicennia albamampu untuk menyerap logam berat (Pb dan Cu) yang berada pada dilingkungannya namun mobiltas kedua logam berat pada mangrove akan mengalami mekanisme fitoremediasi yang berbeda (fitostabilisasi untuk Cu ; fitoekstraksi untuk Pb).Kata Kunci:Avicennia alba, Fitoremediasi, Faktor Biokonsentrasi, Faktor Translokasi, Logam Berat (Pb danCu)

Abstract

The cultivation of giant gourami is constrained by its high mortality due to low resistance to diseases. Resistance is an inherited character from the parental to their seeds. High resistance seeds can be selected using molecular marker, such as Major Histocompatibility complex (MHC) gene. Resistance character is assumed to be different among individual from different broodstocks and is suggested related to their genetic constituent.  This research aims to analyze the resistance of sowang gouramy seeds from different broodstocks and describe genetic character of seeds from different broodstocks. An explorative survey was perfomed. One hundred individuals were taken purposively from Balai Benih Ikan Sikamaju Ciamis West Java and hundred individuals were bought from fish farmer in Ciamis West Java. Sampling was performed in 2015 for the first seed group and in 2016 for the second seed group. Samples were subjected to Aeromonas hydrophila and Pseudomonas aeruginosa infection. The fragments of MHC gene were amplified using PCR technique from eight individual of first group and six individuals of second group. The resistance characteristic was analyzed using simple mathematics based on the number of living seeds compared total infected seeds and molecular characteristics was analyzed descriptively based on DNA band pattern. Different resistance to A. hydrophila was observed between seed groups from different broodstocks. The seeds group from the first broodstocks showed lower resistance level with the value of 29% than that from the second broodstocks with the resistance value reached of 100%. Both seed groups also showed resistance differences to P.aeruginosa, although  not as high as A.hydrophila infection. The differencies were also reflected in their MHC gene between seed groups from two different broodstocks. The amplication of MHC gene of the seeds from the first broodstacks resulted of 585 bp and 400 bp length fragments, while from those second broodstocks was only resulted of 400 bp frament. The differences on DNA band pattern between seed groups indicate a different molecular characteristics among seeds from different broodstocks.Usaha budidaya ikan gurami terhambat oleh tingginya mortalitas benih karena rendahnya resistensi terhadap penyakit. Resistensi merupakan sifat yang diwariskan dari tetua ke anakan. Benih yang resisten dapat diseleksimenggunakan marka molekuler seperti gen Major Histocompatibility complex (MHC). Sifat resisten diduga berbeda diantara benih yang beraasal dari induk berbeda dan diduga terkait dengan kompenen genetik yang dimiliki. Tujuan penelitian ini adalah untuk mengetahui sifat reisten dan karakter molekuler benih gurami sowang asal induk berbeda. Fragmen gen MHC diamplifikasimenggunakan teknik PCR. Sifat resistensi dianalisis menggunakan perhitungan matematika sederhana berdasarkan jumlah benih hidup dibagi jumlah total benih yang diinfeksi, sedangkan karakter molekuler dianalisis secara deskritif berdasakan pola pita yang dihasilkan. Kedua kelompok benih memiliki sifat resistensi berbeda terhadap Aeromonas hydrophila. Benih dari induk pertama memiliki sifat resistensi lebih rendah dengan nilai kelangsungan hidup sebesar 29% daripada kelompok benih dari induk kedua yang memiliki kelangsungan hidup mencapai 100%. Kedua kelompok benih juga memperlihatkan perbedaan sifat resisten terhadap P. aeruginosa, meskipun perbedaannya tidak sebesar terhadap A.hydrophila. Perbedaan tersebut juga tercermin pada gen MHC kedua kelompok benih. Pada kelompok benih pertama dihasilkan dua fragmen gen MHC dengan ukuran 585 pb dan 400 pb, sedangkan dari kelompok benih kedua hanya dihasilkan fragmen berukeuran 400 pb. Perbedaan pola pita diantara kedua kelompok benih tersebut merupakan idikasi adanya perbedaan karakter molekuler pada benih yang berasal dari dua induk berbeda

Abstract

The principle of sperm preservation is to prolong the viability of spermatozoa by reducing the degree of metabolism during storage at low temperatures, and one method involved was a cryoprotectant as a sperm protector. This study aimed to determine the best type of cryoprotectant for refrigeration storage of goldfish Carrasius auratus sperm. A completely randomized design was used, and five types of cryoprotectant were tested, namely Methanol, Ethanol, Ethylene Glycol, Glycerol, and DMSO at a 10% concentration combined with 15% egg yolks. The sperm was diluted with Ringer’s solution and stored at 4⁰C for 48 hours. The ANOVA test revealed that cryoprotectant significantly affected the motility and viability of sperm after 48 hours of refrigeration (P0.05). The results showed that 10% DMSO combined with 15% egg yolk could maintain sperm motility and viability better than other treatments, with values of 85.80% and 86.50%, respectively, which were significantly different from the other treatments. Glycerol produced the second-best sperm quality with motility and viability values of 71.13% and 74.13%, respectively. Therefore, DMSO is the most effective cryoprotectant for refrigeration storage of goldfish sperm.
