Abstract

The flyover development today is very much at all to do because it is one solution as degrading congestion and lifter segment flyover is one important tool in the construction of flyovers. This final project offers an example of the calculation and planning lifter segment fly over the beam structure for lifting can be separated pairs which can later be changed in accordance with the specification segment flyover to be lifted. The final project is expected to be one of the references manufacture segments lifter fly over. This design uses Pahl and Beitz method and the results of this research. Specifications lifter segment fly over with beam structure for lifting to be loose tide is Lifting Equipment; Wire rope with two types of options on each drum are strands left and right torsion. Mechanism trolley; Can move on the path along the 3,019 mm, diameter the wheel trolley 381 mm, Trolley the wheel shaft diameter: 12 cm or 120 mm with material JIS S45C. Struktur lifter; Beam lifting using a beam with a weight per unit length of 1.97 N / mm with JIS G3101 SS540 material along the 4900 mm and a surface area of retaining cylindrical pedestal A of 5024 mm2 with material JIS G3101 SS540. The mechanism of motion lifter can move on the path along the 4000 mm. Wheel lifter diameter 533.4 mm. Hydraulic of lifters driver using a double acting hydraulic with a maximum

Abstract

Seiring berkembangnya ilmu dan teknologi dalam segala bidang khususnya dalam bidang  otomotif dan industri membuat kebutuhan akan energi semakin meningkat hal ini mengakibatkan semakin menipisnya cadangan bahan bakar fosil yang selama ini dipergunakan dalam memenuhi kebutuhan  tersebut. Semakin minimnya cadangan ini mendorong manusia untuk mencari energi alternatif yang dapat mengurangi penggunaan bahan bakar minyak bumi atau bahkan dapat menggantikannya. Salah satu energi alternatif adalah minyak jarak.Minyak jarak dicampur dengan biosolar murni dalam kadar 10%, 15% dan 20 % minyak jarak sehingga dapat digunakan untuk bahan bakar mesin diesel. Penelitian dilakukan  terhadap mesin diesel satu silinder di laboratorium  prestasi mesin di Jurusan Teknik Mesin Fakultas Teknik Universitas Sultan Ageng Tirtayasa. Hasil penelitian torsi mesin diesel menurun jika solar diberi campuran minyak jarak  untuk semua kondisi putaran mesin. Konsumsi bahan bakar motor diesel dengan bahan bakar campuran minyak jarak dan biosolar campuran 10 % lebih irit pada putaran mesin 1500 dan 2000 rpm bila di bandingkan dengan campuran 15%, 20% dan tanpa campuran.
