Abstract

The cooling system at work of a gasoline engine functions as a protective engine by absorbing heat. Engine heat is produced from combustion of fuel in the cylinder. The heat is something that is deliberately created to produce energy, but if left unchecked will cause excessive heat (over heating effect). Excessive heat is the cause of changing mechanical properties as well as the shape of the engine components. The purpose of the study was to determine the temperature of the cooling water on the convector / radiator on the convector / radiator on the ferroza official car that has been modified using a multi point injection system. This cooling system does work simultaneously with the combustion system, so as to produce engine work which is the output of the engine. The cooling system is a support system of engine work. The system is not the main system that is the basis of the engine  to do work and effort, but both systems have a very vital function.

Abstract

A hovercraft is an amphibious vehicle that works on an air cushion, capable of traveling on land and water terrains. This vehicle is driven by two systems, namely the lifting system and the propulsion system. The propulsion system functions to produce a thrust that will drive the hovercraft vehicle forward. The thrust is influenced by engine speed, transmission, shaft rotation, fan design, air flow speed, flow rate mass, and air discharge. This research method is carried out by varying the engine speed, starting from 1000rpm, 1200rpm, 1400rpm, 1600rpm, 1800rpm, 2000rpm, 2200rpm rotation. The results of the research and data processing showed that the higher the rotation of the shaft, the greater the thrust generated. Where at a minimum engine speed of 1000 rpm, the shaft rotation of 436 rpm produces a thrust of 11.794 Newton. Whereas at the maximum 2200 rpm engine speed, the 1060 rpm shaft rotation produces a thrust of 87.664 Newton.

Abstract

Magasen drum untuk senjata senapan serbu SS1 V1 Pindad menggunakan pegas spiral untuk menggerakkan munisi masuk kedalam kamar senjata. Dimana pegas spiral yang digunakan sekarang sudah sulit ditemukan dipasaran, Dari permasalahan diatas, maka penulis berencana untuk“Memodifikasi pegas spiral pada magasen drum” yang sesuai dengan pegas yang aslinya. Dengan harapan pegas yang dimodifikasi dapat mempunyai kualitas dan kekuatan bahan yang mendekati ataupun bisa melebihi pegas aslinya.Maka untuk memodifikasi pegas yang baru, diperlukan beberapa pengujian diantaranya uji komposisi kimia supaya bisa mengetahui jenis bahan yang digunakan, Uji torsi dimana bertujuan untuk mengetahui gaya putar  yang bekerja pada magasen drum serta beban yang diberikan pada pegas sampai pegas mengalami patah dan uji kekerasan dimana pada pengujian bertujuan untuk mengetahui sifat kekerasan dari bahan.Dari hasil pengujian komposisi  kimia bahan yang digunakan pada pegas spiral yaitu baja paduan  rendah.  Dan dari perhitungan jumlah keseluruhan dari gaya gesek ditambahkan dengan gaya berat didapatkan nilai :19,26 N.  Bahan yang digunakan aman dan mampu menahan beban maksimum karena nilai tegangan ijin bahan (60 N/mm2), lebih besar dari tegangan kerja (2,405 N/mm2 ). Dari  hasil  perhitungan   untuk mencari dimensi  pegas didapatkan nilai luas penampang pegas sebesar : 0,008 m2. Dimana dari hasil yang diperoleh dapat tentukan : Lebar (b) : 0,005 m dan tebal  (t) : 0,0016 m. Sedangkan untuk nilai panjang (l) sebesar : 800 mm.
