Judul: Penambahan probiotik dengan dosis berbeda terhadap kinerja pertumbuhan ikan nila merah (Oreochromis niloticus)
Abstrak: This research aims to test the effect of the addition of probiotics with different doses on the growth performance of Red tilapia (Oreochromis niloticus). The feed used in this research is the artificial diets with protein levels of 31.75% in added probiotic commercial Power Lac® with a different dose of a feed A (0 g/kg feed), B (0,25 g/kg feed), C (0,50 g/kg feed), and D (1 g/kg feed). Fish used is juvenile red tilapia with average body weight of 13,67±0,22 g were reared in the 3x2x0,7 cm3 bath with density of 50 fish/bath. Fish were reared for 151 days and feed 3 times daily at satiation levels. The results of research showed that treatment C with the addition of probiotic 0,50 g/kg feed gives the best results compared with others in improving the growth performance of red tilapia (Oreochromis sp).

Judul: Application of Probiotics from Different Genera to Improve Growth Performance and Health Status of Tilapia Oreochromis niloticus Fry
Abstrak: Sejalan dengan perkembangan usaha budidaya ikan nila, terdapat beberapa masalah yang dihadapi pembudidaya salah satunya penyakit infeksius. Penyakit infeksius dapat mengganggu sistem metabolisme, memengaruhi pertumbuhan bahkan kematian massal. Penggunaan probiotik dapat menjadi alternatif untuk mencegah penyakit infeksius. Penelitian ini bertujuan menganalisis aplikasi probiotik dengan genus berbeda, yaitu S. lentus L1k dan B. cereus BR2 melalui pakan dalam meningkatkan kinerja pertumbuhan dan status kesehatan benih ikan nila. Ikan uji yang digunakan adalah ikan nila dengan panjang 5,22±0,33 cm dan bobot 2,23±0,10 g. Ikan dipelihara selama 42 hari dan diberi pakan suplementasi dengan pemberian pakan tiga kali sehari secara at satiation. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yang terdiri dari K (kontrol), S (S. lentus 106 CFU mL-1 ), B (B. cereus BR2 106 CFU mL-1 ), SB (S. lentus L1k 106 CFU mL-1 + B. cereus BR2 106 CFU mL-1 ). Hasil penelitian menunjukkan bahwa ikan nila yang diberi probiotik monospesies S. lentus L1k dan B. cereus BR2, serta kombinasi keduanya mampu meningkatkan kinerja pertumbuhan dan status kesehatan benih ikan nila. Hasil penambahan probiotik monospesies S. lentus L1k dan B. cereus BR2 tidak memberikan efek berbeda dengan penambahan probiotik dual-spesies S. lentus L1k dan B. cereus BR2.

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.
