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: Growth Performance of Common Carp Cyprinus carpio With Four Different Commercial Feeds
Abstrak: Pakan yang diberikan pada ikan mas harus memiliki kandungan nutrien yang dapat dicerna dengan baik oleh ikan mas sehingga ikan mas dapat tumbuh secara optimal. Penelitian ini bertujuan mengevaluasi kinerja pertumbuhan ikan mas (Cyprinus carpio) yang diberi pakan empat merek berbeda dengan kandungan protein yang sama. Penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga ulangan, yaitu pakan komersial A (27,88%), pakan komersial B (27,86%), pakan komersial C (27,94%), dan pakan komersial D (27,85%). Ikan mas yang digunakan memiliki bobot 13,27 ±0,01 g/ekor dengan padat tebar 15 ekor per akuarium, dipelihara selama 50 hari. Parameter yang diamati, yaitu rasio konversi pakan (RKP), tingkat kelangsungan hidup (TKH), jumlah konsumsi pakan (JKP), laju pertumbuhan spesifik (LPS), rasio efisiensi protein (REP), retensi protein (RP), retensi lemak (RL), dan average daily gain (ADG). Pemberian pakan D menunjukkan kinerja pertumbuhan pada ikan mas yang lebih baik dibandingkan dengan pakan lainnya., The feed given to common carp must contain nutrients that can be digested properly by common carp so that common carp can grow optimally. This study aims to evaluating the performance of common carp (Cyprinus carpio) growth when provided with four different brands of feed with the same protein content. The study used a completely randomized design (CRD) with four treatments and three replications, namely commercial feed A (27,88%), commercial feed B (27,86%), commercial feed C (27,94%), and commercial feed D. (27,85%). The common carp used weighed 13,27 ± 0.01 g/individuals with a stocking density of 15 individuals per aquarium, reared for 50 days. Parameters observed were feed conversion ratio (FCR), survival rate (SR), total feed consumption (TFC), specific growth rate (SGR), protein efficiency ratio (PER), protein retention (PR), fat retention (FR), and average daily gain (ADG). D feeding showed better growth performance in common carp compared to other feeds

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.
