Evaluation of Larvae Production and Growth of Juvenile Red Tilapia NIFI F1 During the Nursery Phase

Salah satu upaya yang dapat dilakukan untuk meningkatkan kualitas genetik yaitu melalui program pemuliaan. Per-baikan karakter reproduksi dan pertumbuhan dapat digunakan sebagai indikator keberhasilan seleksi. Penelitian ini bertujuan untuk mengevaluasi produksi larva dan pertumbuhan benih ikan nila merah NIFI F1 dari induk seleksi dan kontrol. Kegiatan dilaksanakan selama empat bulan di Balai Riset Pemuliaan Ikan. Pemijahan dilakukan di kolam air tawar pada hapa 1 m x1 m. Perbandingan induk ikan nila jantan dan betina 1:1. Larva yang sudah dipanen dimasukkan pada hapa pendederan ukuran 2x2x1 m3 dengan padat tebar 125 ekor m-2 . Selama pendederan , larva diberi pakan (protein 38-42%) secara ad libitum tiga kali sehari pada bulan pertama dan selanjutnya diberi pakan dua kali sehari 15-20% dari biomassa. Pakan yang diberikan selama pendederan mempunyai protein berkisar 38-42%. Parameter yang diamati meliputi produksi larva, pertumbuhan, laju pertumbuhan spesifik, dan sintasan. Hasil penelitian menunjukkan produksi larva ikan nila merah seleksi yaitu 540±114 ekor dan kontrol 508±142 ekor. Performa pertumbuhan benih ikan nila merah seleksi menunjukkan hasil yang lebih tinggi dibanding kontrol dengan nilai pertumbuhan panjang 6,33 ±0,43cm, pertumbuhan bobot 6,60±0,52 g, laju pertumbuhan spesifik 7,33±0% g hari-1 serta sintasan 81,50±4,46%, se-dangkan populasi kontrol masing-masing 5,76±0,52 cm; 4,90±0,58 g; 4,50±0,35% g hari-1; dan 74,85±3,26%. Nilai ini menunjukkan bahwa ada peningkatan pertumbuhan sebesar 25,76% pada benih ikan nila merah NIFI F1

Optimasi Pola Penyusunan Barang Dalam Ruang Tiga Dimensi Menggunakan Metode Genetic Algorithms

The good arrangement pattern in the three dimension space, for example container, must be made as optimal as possible to keep the dispatch cost down. Genetic algorithms as the solution search methods which depends on the natural selection to get an individual with the best gene arrangement, is able to give the solution towards how the good arrangement pattern is optimized through iteration process until some generations with reproduction, crossover, and mutation operators. By inserting some input such as the space and goods specification, and the probability of the three genetic algorithms operator, the optimization process will look for the good arrangement pattern based on fitness or the best grade, that is the fewer empty space left

Aplikasi Pemetaan Multi Risiko Bencana Di Kabupaten Banyumas Menggunakan Open Source Software Gis

Banyumas regency is one of regions in Central Java province that is categorized as prone disaster, especially floods and landslides. With these sort of conditions, research is needed that focuses on local scale to conduct multi risk mapping of flood and landslide disasters as an effort to mitigate the disaster in Banyumas regency. Multi risk map of flood and landslide disasters in Banyumas regency made based on Geographical Information System (GIS) using open source software called Quantum GIS. The method used are scoring and weighting, along with overlays between the constituent parameters. From a research using the VCA matrix multiplication, congruity value as much as 66,667% risk of flood, 77,778% risk of landslide and 61,111% against multi risk disasters of flood and landslide. The modeling results of multi risk disasters obtained 51,785% of the area in Banyumas regency is highly at risk disasters, 18,960% is moderately at risk and 29,255% is low at risk of flood and landslide disasters. Quantum GIS can be used as an alternative device to process GIS although there may still be some deficiency may occur in data analysis with vector format which could not perform the union of three shape files or more

Studi Eksperimental Perilaku Hubungan Pelat-Kolom Terhadap Kombinasi Beban Gravitasi Dan Lateral Siklis

. Flat slab structures are widely used for buildings because of its advantages both in structural and architectural aspects. Besides its advantages, there is a weakness leads to a poor structural behavior under combined gravity and lateral load. The weakness is concentrated in slab-column connections, where flexural and shear stresses are accumulated as a resultant of gravity load and unbalanced moment caused by lateral load such as earthquake. To solve the problem, especially in potential earthquake zone such as most of the Indonesia region, it is necessary to conduct researches to improve slab-column connections behavior. This paper reports the result of research conducted using three specimens of half scaled interior slab-column connection sub-assemblages designed using simillar dimensions, materials, and details, except the shear reinforcement details. The first specimen, constructed as a control specimen, used standard stud rails designed to comply with ACI codes. The second and third specimens used modified stud rail details. All specimens were subjected to a constant gravity load simulated by concrete blocks and cyclic lateral displacements ranging from elastic to inelastic responses. The experimental results show that modification of the stud rails significantly improves the specimen behavior especially the stiffness and energy dissipation

Analisis Kinerja dan Kualitas Hasil Kompresi pada Citra Medis Sinar-X Menggunakan Algoritma Huffman, Lempel Ziv Welch dan Run Length Encoding

Technological progress in the medical area made medical images like X-rays stored in digital files. The medical image file is relatively large so that the image needs to be compressed. The lossless compression technique is an image compression where the decompression results are the same as the original or no information lost in the compression process. The existing algorithms on lossless compression techniques are Run Length Encoding (RLE), Huffman, and Lempel Ziv Welch (LZW). This study compared the performance of the three algorithms in compressing medical images. The result of image decompression will be compared to its performance in the objective assessment such as ratio, compression time, MSE (Mean Square Error) and PNSR (Peak Signal to Noise Ratio). MSE and PSNR are used for quantitative image quality measurement for subjective assessment assisted by three experts who will compare the original image with the decompression image. Based on the results obtained from the objective assessment of compression performance of RLE algorithm showed the best performance by yielding ratio, time, MSE and PSNR respectively 86,92%, 3,11ms, 0 and 0db. For Huffman, the results can be 12.26%, 96.94ms, 0, and 0db respectively. While LZW results can be in sequence -63.79%, 160ms, 0.3 and 58.955db. For the results of the subjective assessment, the experts argued that all images can be analyzed well
