Abstrak: Growth hormone has been reported to be able to increase fish adaptability to the environment. The purpose of this research was to evaluate the growth performance, feed efficiency, survival rate, and stress level of growth hormone transgenic common carp reared in low temperature (15±0.3 °C). The design used in this research was completely randomized design consisted of 2 treatments (transgenic and non-transgenic) and 3 replications. Transgenic and non-transgenic common carp were reared in 30x25x30 cm3 sized tanks with stocking density of 10 fishes/tank for 30 days. The results showed that there was no significant differences in growth between transgenic and non-transgenic fishes (p>0.05). The survival rate of both transgenic and non-transgenic fishes was 100%. There was also no significant difference found in total feed consumption of transgenic and non-transgenic fishes (p>0.05) and it was 3.43±0.01 g for transgenic and 3.71±0.16 g for non-transgenic. Similar result was also found in feed efficiency between transgenic and non-transgenic fishes (p>0.05), 86.85±14.03% for transgenic and 70.57±8.36% for non-transgenic. Resistance against stress of transgenic fish was presumed higher compared to non-transgenic fish indicated by significant difference in their blood glucose level (p<0.05). Glucose level of transgenic fish (51.56±7.40 mg/dL) was lower compared to non-transgenic fish (90.78±12.44 mg/dL). It could be concluded that transgenic common carp reared in low temperature was presumed has higher resistance against stress compared to non-transgenic fish, meanwhile the survival rate, growth, and feed efficiency of transgenic and non-transgenic common carp were similar.

Abstrak: Fertility and viability are common parameters used to evaluate environmental safety as well as breeding potency of transgenic organisms. This research was performed to evaluate the reproductive performance of F2 generation GH (growth hormone) transgenic male common carp. This research used completely random design with two factors (transgenic and non-transgenic) and three replications. Three GH transgenic male common carp (TGJ) and three non-transgenic (NTJ) fish were crossbred with two non-transgenic female common carps (NTB), resulting 12 families. Parameters observed were semen volume, motility, duration of motility, number of sperm cells, survival of embryo, hatching rate, survival of larva until 3 days old, and morphology of sperm and larva. The results showed that semen volume of TGJ and survival of juvenile in 30 days was higher compared to NTJ (p<0,05), while motility rate, duration of motility, number of sperm cells, survival of embryo, hatching rate, and survival of larva were similar (p>0,05). Furthermore, there were no abnormalities found in sperm morphology of TGJ and the hatched larva of TGJ x NTB crossbred were the same with NT. As the conclusion, reproductive performance of GH transgenic male common carp showed good and similar result with the non-transgenic fish.

Judul: Rendezvous Search Pada Garis Dengan Lebih Dari Dua Pemain
Abstrak: Pada suatu jalan raya, lebih dari dua orang yang bersahabat, telab sepakat akan bertemu di jalan tersebut, tetapi mereka tidak tahu di mana letak sebenarnya mereka akan bertemu. Pencarian dilakukan sepanjang jalan raya tersebut dan untuk memecahkan masalah ini digunakan rendezvous search pada garis. Penelitian ini dilakukan untuk membanlu para pemain agar mereka dapal bertemu datam waktu yang minimum. Pada awal penempatan di jalan raya, setiap pemain mengetahui posisi masing-masing tetapi tidak mengetahui posisi pemain lain. Mereka bergerak dengan kecepatan paling besar 1 untuk bertemu.
