Judul: Induksi Hormonal Pematangan Gonad Sidat Betina (Anguilla bicolor bicolor) dengan Kombinasi Oodev, Gonadorelin dan Hipofisa Lele
Abstrak: 100% ketersediaan benih ikan sidat masih bergantung pada tangkapan alam. Penelitian ini bertujuan untuk menganalisis kinerja premiks hormon Oodev (PMSG, hCG, Anti dopamin, Estradiol-17β) dan gonadorelin yang dikombinasikan dengan hipofisa ikan lele terhadap pematangan gonad induk ikan sidat betina (Anguilla bicolor bicolor). Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan tiga perlakuan kombinasi hormon, yaitu (1) Oodev+gonadorelin (OG) 1 mL/kg, (2) Oodev+gonadorelin 1 mL/kg + HPL 0,25 mL/kg (OGH2,5) dan (3) Oodev+gonadorelin 1 mL/kg + HPL 0,5 mL/kg (OGH5), dengan delapan ulangan individu pada masing-masing perlakuan. Metode penyuntikan yang digunakan adalah penyuntikan secara intramuskular setiap satu minggu selama 12 minggu pemeliharaan dengan ikan sidat berukuran 599,52 ± 67,50 g/ekor (62,36 ± 2,87 cm). Hasil penelitian menunjukkan bahwa nilai PBM mengalami penurunan. Nilai PPM, IHS, dan indeks mata mengalami peningkatan, sedangkan nilai DTSI mengalami fluktuasi. Nilai IGS meningkat hingga 1,12-3,37%. Perlakuan OGH2,5 memberikan hasil terbaik dalam mempercepat pematangan gonad ikan sidat betina dengan nilai IGS sebesar 6,57%. Gonad pada perlakuan terbaik telah sampai pada tahap vesikula lipid dengan hasil histologi berada pada fase vitellogenik akhir. Dosis optimal penggunaan hipofisa lele terhadap kombinasi Oodev dan gonadorelin untuk pematangan gonad sidat betina adalah 0,3 mg/kg., 100% of the availability of eel fry still depends on natural catches. This study aimed to analyze the performance of the premix of Oodev hormone (PMSG, hCG, Anti- dopamine, Estradiol-17β) and gonadorelin combined with catfish pituitary on the gonad maturation of female eel (Anguilla bicolor bicolor) broodstock. The experimental design used was a completely randomized design with three hormone combination treatments, namely (1) Oodev+gonadorelin (OG) 1 mL/kg, (2) Oodev+gonadorelin 1 mL/kg + HPL 0,25 mL/kg (OGH2,5) and (3) Oodev+gonadorelin 1 mL/kg + HPL 0.5 mL/kg (OGH5), with eight individual replicates for each treatment. The injection method used was intramuscular injection every week for 12 weeks of rearing with eels measuring 599,52 ± 67,50 g/head (62,36 ± 2,87 cm). The results showed that the PBM value decreased. The PPM, IHS, and eye index values have increased, while the DTSI values have fluctuated. IGS value increased up to 1,12-3,37%. OGH2,5 treatment gave the best results in accelerating the gonadal maturation of female eels with an IGS value of 6,57%. The gonads in the best treatment had reached the lipid vesicle stage with the histological results being in the late vitellogenic phase. The optimal dose of using the catfish pituitary against the combination of Oodev and gonadorelin for gonad maturation of female eels is 0,3 mg/kg.

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

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.
