Judul: Pertumbuhan dan Kelangsungan Hidup Ikan Betok yang Direndam Hormon Pertumbuhan Ikan Kerapu Kertang Rekombinan dengan Dosis Berbeda pada Umur 12 Hari.
Abstrak: The study was conducted to determine the effectiveness of recombinant giant grouper growth hormone (rElGH) applied to 12-day-old climbing perch by immersion at different doses. The effectiveness test based on growth and survival rates were performed by four different rElGH doses; 0, 3, 6, and 12 mg/L in triplicates. Before immersion process was conducted, the fish were shocked in 3% saline solution for 2 minutes. Then immersion was conducted for 2 hours in rElGH solution. That solution was made by mixing the BSA 0.01% and rElGH in 0.5% saline water. The result showed that immersed juvenile fish in 12 mg/L rElGH dose increased 4% of biomass than controls.

Judul: Growth and Survival of Climbing Perch Anabas testudineus Juveniles Immersed in Recombinant Giant Grouper Growth Hormone at Different Dose
Abstrak: Penelitian ini dilakukan untuk menentukan dosis perendaman hormon pertumbuhan rekombinan ikan kerapu kertang (rElHP) yang menghasilkan pertumbuhan dan kelangsungan hidup benih ikan betok tertinggi. Dosis rElHP yang diberikan, yaitu 3 mg/L, 6 mg/L, dan 12 mg/L serta tanpa pemberian rElHP sebagai kontrol. Benih ikan sebanyak 200 ekor yang berumur 6 hari setelah menetas (habis kuning telur) direndam ke dalam 200 mL larutan rElHP selama 2 jam. Ikan dipelihara dalam akuarium (30x20x20 cm) dengan padat tebar 20 ekor/L selama 8 minggu dan diberi pakan rotifer, naupli Artemia dan cacing sutera 4 kali dalam sehari secara ad libithum serta pakan buatan at satiation. Hasil penelitian menunjukkan bahwa panjang baku benih ikan betok yang diberi perlakuan perendaman rElHP dengan dosis 12 mg/L (4,62 cm) lebih tinggi (P<0,05) dibandingkan dengan perlakuan 6 mg/L (4,56 cm), 3 mg/L (4,46 cm), dan kontrol (4,49 cm). Biomassa ikan yang diberi perlakuan perendaman rHP dengan dosis 12 mg/L (529,01 g) juga lebih tinggi (P<0,05) daripada perlakuan 6 mg/L (487,55 g), 3 mg/L (476,18 g), dan kontrol (416,17 g). Laju pertumbuhan spesifik tidak berbeda antar perlakuan, dan kontrol (P>0,05). Tingkat kelangsungan hidup benih ikan betok perlakuan 12 mg/L lebih tinggi dibandingkan perlakuan lain, dan kontrol. Dengan demikian perendaman benih dalam larutan rElHP dengan dosis 12 mg/L dapat diaplikasikan untuk meningkatkan pertumbuhan, dan kelangsungan hidup ikan betok.

Judul: Klasifikasi Sidik Jari Menggunakan Support Vector Machine Dengan Feature Berbasis Minutiae Menggunakan Metode Region
Abstrak: Manual fingerprint classification proceeds by carefully inspecting the geometric characteristics of major ridge curves in a fingerprint image. This research proposed an automatic approach of identifying the geometric characteristics of ridges based on minutiae position and angle. Position and angle of minutiae are analyzed using region method. Region was used to discretize the number of minutiae. Positions of minutiae in a region give information about its relation to another region. Angles of minutiae indicate the ridge flow direction. Support vector machine, a binary classifier, is used to classify the fingerprint based on those characteristics. In this research, the classes are left loop, right loop, whorl, arch and tented arch. This research used 2695 fingerprint images from NIST. Classification performance is measured using 3-fold cross validation method. This research achieved 79.7 % accuracy. As we only used local features in this research, further research needs to be conducted especially to investigate global features.
