Judul: Perencanaan Sistim Irigasi Curah Berdasarkan Kapasitas Alat dan Kebutuhan Tambahan Air di Kebun Bangelan PT Perkebunaan XXIII
Abstrak: Tujuan perencanaan ini adalah untuk mendapatkan suatu kapasitas sistim irigasi curah yang mempunyai efisiensi pemakaian air relatif tinggi dengan tolok ukur keseragaman pemakaian air, sifat fisik tanah dan kondisi iklim setempat serta menentukan kebutuhan tambahan air untuk setiap daerah irigasi. Pelaksanaan irigasi curah dilakukan pada periode defisit air yaitu sebagai tambahan air aldbat suplai air dari curah hu jan tidak mencukupi bagi kebutuhan air tanaman (crop water requirement). Berdasarkan evapotranspirasi tanaman puncak dan curah hujan efektif bulanan, periode bulan Juni sampai Oktober terjadi kekurangan suplai air hujan. Pada bulan Juni 70.66 mm, Juli 95.73 Rata-rata kekurangan air mm, Agustus 106.79 mm, September 75.80 mm dan Oktober 28.17 mm.

Abstrak: Water balance is the balance of the input and output of water somewhere at a certain period, so it can be to determine the amount of the excess or shortage of water. This study aimed to analyze the flow of water and the excess water needs that occur at BBPTP. The procedure consisted of field studies, literature review and data analysis. Based on the analysis, the direction of water flow in the area around the research flowing to the south where there is a Cijengkol river downstream water flow. Based on the analysis of the water needs of the consolidation that has been done can be concluded highest evapotranspiration values occurred in October that is 7.13 mm/day. The highest value of water demand in October is 2.10 lt/sec/ha. The maximum irrigation discharge occurs in the irrigation channel number 7 is 28.01 lt/sec with 13.34 ha area. Based on the analysis of rainfall can be summed value maximum daily rainfall for the area of research at the Center for Rice Research amounted to 76.25 mm with a return period of 2 years and Gumbel distribution. The maximum effluent discharge occurs in the drainage channel number 88 is 117.30 lt / sec with 14.15 ha area.

Judul: Using cytochrome β (Cyt β) gene for species identification of dog, cat, and tiger to ensure food authenticity and drugs
Abstrak: Adulteration food products from animal still happen until now. Species identification method development in food and medicine derived from animal was needed to prevent falsification information. Molecular genetic improvement allows the detection is carried out at the level of DNA, so the results more accurate, although processed. Research on several meat have been conducted by several researchers using DNA mitochondrial DNA (mtDNA). Using mtDNA because it has high copy number in a cell, compared with nuclear DNA. In this case where the amount of extracted DNA is very small or degraded. Gene used as marker specific species is cytochrome β (cyt β) because it has varied sequences. The objective of this research was to study species authentication (i.e. dog, cat, and tiger) to ensure animal origin in product using cyt β gene specific marker. Total DNA samples for each species which identified are three samples were consisting blood (cat), cooked meat (dog), feces (tiger), and as a comparison used blood sample from several animal (i.e. goat, chicken, cattle, sheep, horse, rat) and pork. Reverse primer specific for dog, cat, and tiger was designed using MEGA 5 software. DNA extraction and fragment amplification was conducted using phenol-chloroform and multiplex PCR method, respectively. Multiplex PCR is a variant of PCR which many primers were used together for amplification of multiple region. This research showed that different length of amplification for the species tested (dog, cat, and tiger) were 523, 331, 319 bp, respectively; and for the comparison species (goat, chicken, cattle, sheep, pig, horse, and rat) were 157, 227, 274, 331, 398, 439, and 603 bp, respectively. Species specificity also indicated by high reverse primer homology percentage. Specific fragment amplification on genome pool with closed fragment length should be separate to avoid band overlapped between species. Taxonomy hierarchy (i.e. dog, cat, and tiger) could be distinguished to the species level.
