Judul: Hybridization Performance of Denisoni Sahyadria denisonii with Rosy Barb Pethia conchonius
Abstrak: Hybridization can produce offspring with better characteristics than their original parent but the opportunity to be succeed is one of the limiting factors. This study aims to identify the successful of hybridization between denisoni and rosy barb. This study was conducted with exploration method using random design complete (RAL) with treatments: DD (denisoni ♀ >< denisoni ♂), BB (rosy barb ♀ >< rosy barb ♂), DB (denisoni ♀ >< rosy barb ♂), BD (rosy barb ♀ >< denisoni ♂) and 3 repetition. The mating was done artificially using Ovaprim® and stripping. Eggs hatched and the larvae reared for 7 days after hatching. The parameters observed including semen volume, spermatocrit, sperm morphology, motility, viability, fecundity, FR, HR, and SR. Hybridization between denisoni and rosy barb was possible for BD treatment otherwise was impossible with differences towards sperm physiological and morphological characteristics, motility, viability, and fecundity between denisoni and rosy barb, also FR, HR, and SR value was significantly different (P<0,05) between treatments., Hibridisasi dapat menghasilkan benih dengan karakter yang lebih unggul daripada tetuanya namun memiliki keterbatasan berupa peluang keberhasilan dalam melakukan kawin silang. Penelitian ini bertujuan mengidentifikasi keberhasilan hibridisasi antara ikan denisoni dengan ikan barbir. Penelitian ini dilakukan dengan metode eksplorasi menggunakan rancangan acak lengkap (RAL) dengan perlakuan: DD (denisoni ♀ >< denisoni ♂), BB (barbir ♀ >< barbir ♂), DB (denisoni ♀ >< barbir ♂), BD (barbir ♀ >< denisoni ♂) dengan 3 kali ulangan. Pemijahan dilakukan secara buatan dengan bantuan induksi Ovaprim® dan proses stripping. Telur ditetaskan dan larva yang dihasilkan dipelihara hingga 7 hari pascatetas. Parameter yang diamati meliputi volume cairan semen, spermatokrit, morfologi sperma, motilitas, viabilitas, fekunditas, FR, HR, dan SR. Persilangan antara ikan denisoni dan ikan barbir memiliki peluang pada perlakuan BD namun tidak untuk sebaliknya dengan adanya perbedaan terhadap karakteristik fisiologis dan morfologi sperma, motilitas, viabilitas, dan fekunditas antara ikan denisoni dan ikan barbir serta adanya perbedaan yang signifikan (P<0,05) terhadap nilai FR, HR, dan SR antar perlakuan.

Judul: Kinerja Produksi dan Kinerja Usaha pada Pendederan Ikan Denisoni (Puntius denisonii) dengan Padat Tebar Berbeda
Abstrak: Ikan denisoni (Puntius denisonii) merupakan ikan endemik asal India yang telah banyak diperjualbelikan karena kekhasan warna tubuhnya. Banyaknya permintaan pasar di Indonesia membuat ikan denisoni banyak dibudidayakan di Indonesia. Produktivitas budidaya ikan tersebut masih rendah karena rendahnya padat tebar. Penelitian ini bertujuan menganalisis kinerja produksi dan kinerja usaha pada pendederan ikan denisoni dengan padat tebar berbeda. Penelitian ini menggunakan akuarium berukuran 2,0×0,5×0,3 m3. Perlakuan yang digunakan adalah padat tebar, yaitu 2 ekor L-1 (A), 3 ekor L-1 (B), dan 4 ekor L-1 (C) dengan tiga ulangan pada tiap perlakuan. Ikan yang ditebar berukuran panjang rata-rata 1,72±0,09 cm dan bobot rata-rata 0,15±0,02 g. Ikan dipelihara selama 35 hari dengan pemberian pakan berupa cacing sutera (Oligochaeta aquatic). Pengelolaan kualitas air dilakukan dengan pergantian air sebanyak 60% selama dua kali dalam seminggu. Hasil yang didapatkan menunjukkan bahwa produktivitas terbaik terjadi pada perlakuan padat tebar 4 ekor L-1 , yaitu sebesar 37.827 ekor m3 tahun-1 dengan keuntungan Rp575.831.829, HPP sebesar Rp781, R/C sebesar 1,87, dan PP sebesar 0,34 tahun atau 4 bulan 5 hari. Kata kunci: budidaya, denisoni, keuntungan, padat tebar, produktivitas, Denisoni fish (Puntius denisonii) is an endemic fish from India which is widely traded because of the unique color of its body. The large market demand in Indonesia makes denisoni fish are widely cultivated in Indonesia. However, productivity is still low due to the low stocking density used. This research aims to analyze the optimal stocking density in denisoni fish nurseries with higher stocking density and 60% air change through a study of production performance and business performance. This research used an aquarium measuring 2,0×0,5×0,3m3. There were three treatments used, namely stocking density of 2 fish L-1 (A), 3 fish L-1 (B), and 4 fish L-1(C) with three replications in each treatments. Fish stocking size with an initial average weight of 0,15 ± 0,02 g and an initial average length of 1,72 ± 0,09 cm. The fish were maintained for 35 days by feeding them using silk worms (Oligochaeta aquatic). Water quality management is carried out by changing the air by 60% twice a week. The results obtained showed that the best productivity occurred in the stocking density treatment of 4 L-1, namely 37.827 ekor m3 year-1 with a profit of IDR 575.831.829, HPP of IDR 781, R/C ratio of 1,87, and PP of 0,34 years or 4 months 5 days.

Judul: Formulasi TSP (Traveling Salesman Problem) menggunakan ILP (Integer Linear Programming)
Abstrak: TSP is a journey of salesman f?om his origin town (place) to visit n-cities (places) only at once, then return to his origin town (place) with a minimum total distance. Its purpose is to minimize the operating expense that is released by the company. Vehicle route at TSP in the form of a Hamiltonian cycle, that is closed path containing all nodes at the graph which representing a network walk. Its problem is to determine a journey route which is feasible (possibly can be passed by) in such a way the vehicle travelled distance passed the route is minimum.
