Judul: Induksi Maturasi Ikan Sidat (Anguilla bicolor) dengan Menggunakan Kombinasi Hormon Berbeda
Abstrak: Production of Indonesian eel (Anguilla bicolor) juvenile through the hatchery can not be done yet. In this research, induction of Indonesian eel gonadm aturation was performed by hormonal with a combination of pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG) antidopamin and recombinant growth hormone (rGH). This research consisted of five treatments namely: control(NaCl 0,9%), PMSG 20 IU/kg, PMSG 20 IU/kg + antidopamin 10 ppm/kg, PMSG 20 IU/kg + antidopamin 10 ppm/kg + rGH 10 μg/kg dan PMSG 20 IU/kg + HCG 10 IU/kg. Each treatment contained 10 fishes. Hormonal induction was conducted by intramuscular injections, as much as five times at intervals of seven days. Furthermore observations on gonadal development were performed after injection for 21 days.The results showed that the treatment generated pregnancy level of 100%, while control was 0%. The best treatment is PMSG 20 IU/kg + antidopamin 10 ppm/kg+ rGH 10 μg/kg, seen from a more mature phase of the gametes, spermatocytes in male and oocytes with perinukleolar phase in female fish. Eel fish at body weight 120.4 to 207.8 g and 40.9 to 43.1 cm of body lenght was male, body weight of 274.8 g and length 47 cm was the intersexual phase eels, while at body weight 323.4 g and length 53 cm was female.

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.

Judul: Klasifikasi dengan Analisis Komponen Utama Kernel
Abstrak: Principal component analysis (PCA) is a special case of the kernel PCA with linear kernel function. The aim of this study is to resolve the data problem that is not linearly separated and to classify an object into a group by using kernel PCA to obtain the smallest classification error. Group classification using kernel PCA is performed by the linear and Gaussian kernel function. The result of the study shows for wine recognition data with the linear and Gaussian (parameter 2.5) kernel function produces 30.889% and 17.416% classification error, respectively
