Judul: Hormonal Induction of Gonads Maturation Female Eel Fish (Anguilla bicolor bicolor) with a Combination of Oodev and Catfish Pituitary
Abstrak: Ikan sidat Anguilla bicolor bicolor merupakan komoditas budidaya dengan potensi pasar yang tinggi diseluruh dunia. Permasalahan pada budidaya sidat terdapat pada keberhasilan pembenihan. Ketersediaan induk ikan sidat matang gonad masih langka dikarenakan sidat tidak dapat bereproduksi pada perairan tawar ataupun wadah budidaya. Penelitian ini bertujuan untuk menganalisis perkembangan kematangan gonad ikan sidat dengan penyuntikan kombinasi hormon Oodev dan hipofisa ikan lele. Metode penelitian yang digunakan adalah metode eksperimen rancangan acak lengkap dengan perlakuan O (Oodev), H5 (Hipofisa ikan lele 0,5 mL/kg), dan OH5 (Oodev + hipofisa ikan lele). Penyuntikan hormon dilakukan 1 kali/minggu selama 12 minggu. Hasil penyuntikan hormon menunjukkan indeks gonadosomatik tertinggi yaitu H5 sebesar 3,57%, OH5 3,00%, dan O 2,70%. Indeks hepatosomatik tertinggi yaitu perlakuan OH5 sebesar 0,95%, O 0,92%, dan H5 0,89%. Digestive tract somatic index tertinggi yaitu perlakuan H5 sebesar 1,50%, O 1,35%, dan OH5 1,33%. Penurunan bobot tertinggi terdapat pada perlakuan H5 sebesar -61 gr, OH5 -45,33 gr, dan O -40,33 gr. Penurunan panjang tertinggi terdapat pada perlakuan O sebesar -1,1 cm, OH5 -0,7 cm, dan H5 -0,6 cm. Indeks mata tertinggi yaitu perlakuan O sebesar 1,50%, H5 1,42%, dan OH5 1,36%. Histologi gonad induk ikan sidat perlakuan OH5 menunjukkan hasil terbaik mencapai fase vitelogenik akhir. Pemberian kombinasi hormon Oodev dan hipofisa ikan lele memberikan pengaruh yang baik terhadap perkembangan gonad ikan sidat. Kombinasi hormon oodev dan hipofisa ikan lele 0,5 mg/mL memberikan hasil terbaik dalam pematangan gonad ikan sidat betina berukuran bobot 675,37 ± 99,97 gr/ekor dan panjang 64,73 ± 4,01cm/ekor dalam waktu pemeliharaan 12 minggu. Kata kunci : Hipofisa ikan lele, ikan sidat Anguilla bicolor bicolor, Oodev, pematangan gonad., Anguilla bicolor bicolor eel is a cultivated commodity with high market potential throughout the world. The problem in eel cultivation is the success of the hatchery. The availability of gonadal mature eel broodstock is still scarce because the eels cannot reproduce in freshwater or in aquaculture containers. This study aims to analyze the development of gonad maturity of eel by injection of a combination of Oodev hormone and catfish pituitary. The research method used was a completely randomized design experimental method with O (Oodev), H5 (catfish hypophysis 5 mL/kg), and OH5 (Oodev + catfish hypophysis) treatments. Hormone injections are carried out once a week for 12 weeks. The results of hormone injection showed the highest gonadosomatic index, namely H5 of 3.57%, OH5 of 3.00%, and O of 2.70%. The highest hepatosomatic index was 0.95% OH5 treatment, 0.92% O, and 0.89% H5. The highest digestive tract somatic index was treated with H5 1.50%, O 1.35%, and OH5 1.33%. The highest weight loss was found in the H5 treatment of -61 g, OH5 -45.33 g, and O -40.33 g. The highest decrease in length was found in the O treatment of -1.1 cm, OH5 -0.7 cm, and H5 - 0.6 cm. The highest eye index was treatment O at 1.50%, H5 at 1.42%, and OH5 at 1.36%. Gonadal histology of broodstock eel OH5 treatment showed the best results reaching the final vitellogenic phase. The combination of the Oodev hormone and catfish pituitary had a good effect on the

Judul: Induction of Gonadal Maturation of Eel Anguilla bicolor bicolor with Oodev and Estradiol-17β through Meal
Abstrak: Ikan sidat (Anguilla sp.) betina matang gonad berukuran >500 g memerlukan waktu pemeliharaan yang panjang sehingga diperlukan metode untuk mempercepat pematangan gonad. Salah satu upaya tersebut yaitu melalui manipulasi reproduksi secara hormonal. Penelitian ini bertujuan mempercepat pematangan gonad sidat menggunakan hormon Estradiol-17β dan Oodev. Sidat berukuran 250-290 g diinduksi dengan hormon Oodev dan Estradiol-17β metode oral melalui pakan yang disuplementasi dengan tepung kunyit 5 g/kg pakan. Penelitian menggunakan rancangan acak lengkap (RAL) tiga perlakuan dan satu kontrol. Padat tebar sebanyak 10 ekor/perlakuan. Dosis hormon perlakuan dicampur dalam pakan terdiri dari kontrol (0 mL/kg ikan hormon), hO2 (1 mL/kg ikan Oodev (PMSG + AD), hO1E3 (1 mL/kg ikan (Oodev (PMSG + AD) + 3 mg E2), dan hO1E6 (1 mL/kg ikan (Oodev (PMSG + AD) + 6 mg E2). Hasil menunjukkan bahwa perlakuan hO1E6 memberikan nilai terbaik untuk LPS (4,004±0,96%/hari), AG (126,456±29,098 cm), IGS (1.30±0,51%), persentasi betina 80%, nilai hematokrit (39,57±3,36%) dan eritrosit ((1,83±0,21)x106 sel/mm3 ) (P<0,05), sedangkan untuk parameter PPM, IHS, diameter mata, faktor kondisi, DTSI tidak berbeda nyata (P>0,05). Pemberian kombinasi hormon 1 mL/kg ikan Oodev dan 6 mL/kg ikan Estradiol-17β dapat mempercepat pertumbuhan bobot, pematangan gonad, dan feminisasi sidat. Kombinasi hormon tersebut dapat menjadi alternatif untuk mempercepat pertumbuhan bobot dan pematangan gonad pada kegiatan budidaya pembesaran dan pembenihan sidat., Eel (Anguilla sp.) mature female gonads measuring >500 g require a long maintenance time so a method is needed to accelerate gonadal maturation. One of these efforts is through hormonal manipulation of reproduction. This study aims to accelerate the gonadal maturation of eels using the hormones Estradiol-17β and Oodev. Eels measuring 250-290 g were induced with the hormone Oodev and Estradiol-17β orally through feed supplemented with turmeric flour 5 g/kg feed. The experimental design used was a completely randomized design (CRD) with three treatments and a control with 10 animals/treatment. The dose of treatment hormone mixed in the feed consisted of control (0 mL/kg fish hormone), hO2 (1 mL/kg Oodev fish (PMSG + AD), hO1E3 (1 mL/kg fish (Oodev (PMSG + AD) + 3 mg E2 ), and hO1E6 (1 mL/kg fish (Oodev (PMSG + AD) + 6 mg E2). The results showed that hO1E6 treatment gave the best value for SGR (4.004±0.96%/day), AG (126.456±29.098 cm ), GSI (1.30±0.51%), 80% female percentage, hematocrit value (39.57±3.36%) and erythrocytes ((1.83±0.21)x106 cells/mm3 ) (P<0 0.05), while for parameters Lm, IHS, eye diameter, condition factor, DTSI was not significantly different (P>0.05).The administration of a combination of hormones 1 mL/kg Oodev fish and 6 mL/kg Estradiol-17β fish could accelerate weight growth, gonadal maturation, and eel feminization.The combination of these hormones can be an alternative to accelerate weight growth and gonad maturation in eel rearing and hatchery cultivation activities.

Abstrak: Existing design of the telephone public network is susceptible to eavesdropping on its voice stream. Consequently, any wire taper can listen to supposedly private conversation. In order to prevent such eavesdropping, we propose a protocols and its implementation for end-to-end voice privacy authenticate as a service available for interested subscribers. Our protocols consist of customer enrollment system, customer authentication system and simulation voice privacy. Protocols that we made are adaptation from Sharif and Wijekesera journal with the title Providing Voice Privacy as a Service over the Public Telephone Network. The result of the process shows how the customer enrolls and how the system process the password, how the system authenticate customer simulate voice privacy.
