Judul: Analisis Gaya Pada Pintu Klep Air PastifasetModel Frame Lurus (PA-FG1)
Abstrak: The rate of food needs is directly proportional to the population growth; must be balanced with the development of agricultural technology innovations that can make use of all existing land conditions. The technology can be used in these circumstances is the application of tidal irrigation. The study aimed to analyze the force that occurs on hydromechanical sluice. Based on the results of the calculation, the maximum value of the placement reaction of HA is 1633.33 N, of HB is 3266.67 N, the value of style vertical slats sluice is 900 N and 3500 N. On the condition when the sluice opened, the greater the angle, the greater openings HA force. This is due to the resultant force of downstream greater than upstream. For sluice with head difference of 0.08 m, aperture angles 45o and 60o have differences with another sluice condition occurs where the force is inversely proportional to discharge. This can happen because the horizontal force component switches to the vertical component. The weight of the door is a major component of the vertical force the door itself. Budget plans are used to construct sluice is Rp177.888.400, -.

Judul: Studi analisis hidrolis pada undersluice sebagai konstruksi pelengkap bendung untuk pengendalian sedimen
Abstrak: Tujuan dari penelitian ini adalah untuk mempelajari pengaruh debit aliran, tinggi lubang undersluice, bukaan pintu undersluice terhadap tinggi muka air di hulu tinggi muka air di hilir, serta kecepatan aliran di lubang, mendekati lubang undersluice, serta di pintu undersluice. 1 Penambahan bukaan pintu undersluice pada keadaan free flow akan mengakibatkan penurunan elevasi di hulu under- sluice, dan sebaliknya. Kecepatan aliran mendekati lubang undersluice semakin kecil dengan setiap penambahan debit. Hal ini diakibatkan karena penambahan elevasi muka air di hulu. Sedangkan pada penambahan debit yang sama kecepatan aliran di dalam lubang undersluice dan kecepatan aliran pada pintu under- sluice akan semakin besar pula. Kecepatan aliran di lubang undersluice akan sama dengan kecepatan aliran pada pintu undersluice. Koefisien pengaliran undersluice (C) didapatkan dengan membuat analisa regresi linear antara debit aliran dan parameter yang mempengaruhinya, sesuai dengan persamaan yang digunakan. Program komputer untuk parameternya pada undersluice dua mempredikS1 dimensi seperti elevası, dan kecepatan aliran. parameter- prototypenya, Hal 101 dilaku- kan dengan terlebih dahulu menentukan tinggi lubang under- sluice rencana.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
