Judul: Evaluasi kualitas pakan berbeda terhadap kinerja pertumbuhan Ikan Mas Cyprinus carpio
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pemberian pakan dengan kualitas berbeda terhadap kinerja pertumbuhan ikan mas (Cyprinus carpio). Ikan mas dengan bobot awal rata-rata 16,88±0,01 g/ekor dipelihara selama 40 hari dalam akuarium berukuran 50x40x35 cm dengan kepadatan 10 ekor/akuarium. Suhu air diatur 28 °C menggunakan heater. Ikan uji diberi tiga jenis pakan yang memiliki kandungan protein berbeda yaitu 31%, 32%, dan 33% dengan rasio energi protein (c/p) sebesar 14 kkal/g. Pemberian pakan dilakukan secara at satiation sebanyak tiga kali sehari pada pukul 08.00, 12.00, dan 16.00 WIB. Parameter penelitian yang diukur adalah kinerja pertumbuhan; jumlah konsumsi pakan, kecernaan protein, kecernaan energi, retensi protein, retensi lemak, laju pertumbuhan harian, efisiensi pakan, dan kelangsungan hidup. Hasil penelitian menunjukkan bahwa pakan dengan kadar protein 32% memberikan laju pertumbuhan harian dan efisiensi pakan terbaik pada ikan mas dibandingkan dengan pakan perlakuan lainnya.

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: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
