Judul: Evaluation of the Effectiveness of Commercial Probiotics on the Survival of Carp (Cyprinus carpio) in Tarpaulin Ponds
Abstrak: Probiotik sebagai suplemen tambahan pada pakan sudah umum digunakan pada proses budidaya perikanan. Probiotik merupakan kumpulan dari mikroba yang digunakan untuk meningkatkan kesehatan usus dan sistem kekebalan tubuh. Peneletian ini mengkaji efektivitas probiotik komersial terhadap kelangsungan hidup ikan mas (Cyprinus carpio) pada kolam terpal dengan air mengalir di daerah Situdaun, Bogor. Metode yang digunakan dalam pengaplikasian probiotik yaitu metode coating dengan parameter yang diukur yaitu : rata-rata bobot dan panjang ikan, total ikan yang hidup, Survival Rate (SR), Food Cenvertion Ratio (FCR), pertumbuhan laju mutlak, dan laju pertumbuhan harian. Pengumpulan data dilakukan dengan metode sampling yang dilakukan setiap hari. Hasil penelitian menunjukan perlakuan probiotik komersial lebih baik dibandingkan kontrol pada parameter : rata-rata bobot dan panjang ikan (51,711g , 14,23 cm), pertumbuhan laju mutlak (17,97 cm), Food Conversion Ratio (1,179), dan laju pertumbuhan harian (0,60 cm). Namun, terdapat parameter perlakuan probiotik komersial tidak lebih baik dibandingkan kontrol yaitu total ikan yang hidup (38 individu), dan Survival Rate (47,5 % ). Hasil dari penelitian ini menunjukan aplikasi probiotik komersial cukup efektif untuk budidaya ikan pada kolam terpal pada air mengalir., Probiotics as additional supplements in feed are commonly used in the fisheries cultivation process. Probiotics are a collection of microbes used to improve intestinal health and the immune system. This research examines the effectiveness of commercial probiotics on the survival of carp (Cyprinus carpio) using tarpaulin ponds in Situdaun, Bogor. The method used in the application of commercial probiotics is the coating method with the parameters measured, namely: average weight and length of fish, total fish alive, Survival Rate (SR), Food Conversion Ratio (FCR), absolute growth rate, and daily growth rate. Data collection was carried out using a sampling method that was carried out every day. The results showed that probiotic treatment was better than control in the following parameters: average weight and length of fish (51.711g, 14.23 cm), absolute growth rate (17.97 cm), Food Conversion Ratio (1.179), and daily growth rate (0.60 cm). However, there were parameters of commercial probiotic treatment that were not better than control, namely the total number of fish alive (38 individuals), and Survival Rate (47.5%). The results of this study indicate that commercial probiotic application is quite effective for fish farming in tarpaulin ponds in flowing water.

Judul: Effectiveness of Commercial Astaxanthin Supplementation in Feed on the Growth Performance of Common Carp Cyprinus carpio
Abstrak: Ikan mas termasuk salah satu ikan dengan laju pertumbuhan yang cukup tinggi. Astaxanthin adalah antioksidan dari golongan karotenoid yang dapat mempengaruhi pertumbuhan ikan. Penelitian ini bertujuan mengevaluasi efektivitas suplementasi astaxanthin komersial pada pakan terhadap kinerja pertumbuhan ikan mas (Cyprinus carpio). Penelitian menggunakan empat perlakuan dan tiga ulangan, yaitu K (0 mg kg-1 pakan), L50 (50 mg kg-1 pakan), L100 (100 mg kg-1 pakan), dan L150 (150 mg kg-1 pakan). Ikan dipelihara dengan kepadatan 12 ekor per akuarium selama 60 hari. Pemberian pakan uji dilakukan secara at satiation dengan frekuensi sebanyak tiga kali sehari, yaitu pukul 08.00, 12.00, dan 16.00. Parameter yang diamati yaitu laju pertumbuhan spesifik, tingkat kelangsungan hidup, rasio konversi pakan, jumlah konsumsi pakan, retensi protein, retensi lemak, rasio efisiensi protein, dan feed cost per gain. Suplementasi astaxanthin komersial pada pakan menunjukkan kinerja pertumbuhan yang berbeda nyata (p<0,05) antar perlakuan. Kinerja pertumbuhan ikan mas (Cyprinus carpio) terbaik diperoleh pada pakan dengan penambahan astaxanthin komersial sebanyak 100 mg kg-1 pakan., Common carp is one of the fish with a fairly high growth rate. Astaxanthin is a carotenoid antioxidant which can affect fish growth. This study aims to evaluate the effectiveness of commercial astaxanthin supplementation in feed on the growth performance of common carp (Cyprinus carpio). The research used four treatments and three replications, namely K (0 mg kg-1 feed), L50 (50 mg kg-1 feed), L100 (100 mg kg-1 feed), and L150 (150 mg kg-1 feed). Fish were maintained at a density of 12 fish per aquarium for 60 days. The test feed was given at satiation with a frequency of three times a day, namely at 08.00, 12.00 and 16.00. The parameters observed were specific growth rate, survival rate, feed conversion ratio, amount of feed consumption, protein retention, fat retention, protein efficiency ratio, and feed cost per gain. Astaxanthin commercial supplementation in feed showed significantly different growth performance (p<0.05) between treatments. The best growth performance of common carp (Cyprinus carpio) was obtained with feed supplemented with 100 mg kg-1 of commercial astaxanthin.

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.
