Judul: Efektivitas penambahan Oodev dan melatonin melalui pakan  dalam meningkatkan produktivitas induk ikan badut (Amphiprion  sp.) di BBPBL Lampung
Abstrak: Salah satu komoditas ikan hias air laut yang banyak diminati adalah ikan badut (Amphiprion sp.). Tingginya permintaan pasar perlu diimbangi dengan kegiatan budidaya. Penelitian ini bertujuan mengevaluasi performa reproduksi induk ikan badut dengan pemberian kombinasi oodev dan melatonin melalui pakan. Perlakuan dengan kode K adalah tanpa Oodev dan melatonin, kode O adalah Oodev 1,25 mL kg-1, Kode OMA adalah Oodev 1,25 mL kg-1 + melatonin 0,5 mg kg-1 dan kode OMB adalah Oodev 1,25 mL kg-1 + melatonin 1 mg kg-1 . Jumlah induk yang digunakan 12 pasang dengan kisaran bobot induk jantan 7,2±1,9 g/ekor dan induk betina 16,4±2,8 g/ekor. Induk yang digunakan adalah induk produktif yang baru selesai memijah. Hasil penelitian menunjukkan bahwa penambahan kombinasi Oodev dan melatonin dapat meningkatkan frekuensi pemijahan, mempercepat waktu pemijahan, meningkatkan jumlah telur dan memperoleh pendapatan yang lebih tinggi dibandingkan perlakuan kontrol dan oodev tanpa melatonin. Keseluruhan parameter menunjukkan perlakuan Oodev 1,25 mL kg-1 + melatonin 0,5 mg kg-1 (OMA) merupakan perlakuan terbaik., One of the most popular seawater ornamental fish commodities is clownfish (Amphiprion sp.). The high market demand needs to be balanced with cultivation activities. This study aims to evaluate the reproductive performance of clownfish broodstock by giving a combination of oodev and melatonin through feed. Treatment with code K is without Oodev and melatonin, code O is Oodev 1,25 mL kg-1, code OMA is Oodev 1,25 mL kg-1 + melatonin 0.5 mg kg-1 and code OMB is Oodev 1,25 mg kg-1 + melatonin 1 mg kg-1. The number of broodstock used was 12 pairs with a weight range of male broodstock 7.2±1.9 g/head and female broodstock 16.4±2.8 g/head. The broodstock used were productive broodstock that had just finished spawning. The results showed that the addition of a combination of Oodev and melatonin could increase the frequency of spawning, accelerate spawning time, increase the number of eggs and obtain higher income than the control treatment and Oodev without melatonin. All parameters showed that the Oodev treatment

Judul: The effectiveness of adding Oodev through feed on the reproductive performance of clown fish (Amphiprion percula) in BBPBL Lampung
Abstrak: Ikan badut (Amphiprion percula) merupakan ikan hias air laut potensial budidaya. Produksi ikan badut masih mengandalkan hasil tangkapan dari alam yang menyebabkan kelangkaan sehingga perlu didukung dengan produksi budidaya. Penelitian ini bertujuan mengevaluasi kinerja reproduksi ikan badut budidaya dengan pemberian hormon oodev melalui pakan. Hormon Oodev ditambahkan dalam pakan dengan dosis 0 mL; 0,75 mL; 1,5 mL per kg induk setiap minggu selama 5 minggu sesuai feeding rate (FR) 3%. Setiap perlakuan menggunakan 3 pasang induk sebagai ulangan, masing-masing dipelihara dalam wadah berukuran 60x40x50 cm3 dan volume air 100 L serta dilengkapi dengan sistem flowthrough. Perlakuan hormon oodev melalui pakan selama 35 hari efektif meningkatkan frekuensi pemijahan ikan badut dalam wadah budidaya. Pada dosis hormon oodev 0,75 mL menghasilkan frekuensi pemijahan 3 kali dengan fekunditas absolut 1098 butir/ekor, sedangkan pada dosis oodev 1,5 mL ikan memijah 3 kali namun fekunditas absolut lebih rendah yaitu 775 butir/ekor, dan pada perlakuan tanpa oodev menghasilkan pemijahan 2 kali dengan fekunditas absolut 550 butir/ekor. Aplikasi oodev pada budidaya ikan badut dapat meningkatkan produksi larva dan profit lebih tinggi., Clown fish (Amphiprion percula) is a marine ornamental fish that is potential of cultivation. Clown fish production still relies on catches from nature which lead to scarcity so its need supported by production through aquaculture activities. This study aimed to evaluate the reproductive performance of clown fish in aquaculture with the addition of oodev hormone through feed. Oodev hormone was added to the feed at a dose of 0 mL; 0.75 mL; 1.5 mL per kg broodstock every week for 5 weeks according to a feeding rate (FR) of 3%. Each treatment used 3 pairs of broodstock as replicates, each was kept in a 60x40x50 cm3 and water volume was 100 L with a flow-through system. The oodev traitment was effective in increasing the clownfish spawning frequency in aquaculture tanks. At a dose of 0.75 mL oodev the fish spawned 3 times in 5 weeks with an absolute fecundity of 1098 eggs/individu, while at a dose of 1.5 mL oodev fish spawned 3 times but its absolute fecundity was lower (775 eggs/individu) compared to the control without oodev it was 2 times with absolute fecundity of 550 eggs/individu. The application of oodev in clown fish cultivation can increase larval production and better profit.

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.
