Abstract

Cooling system in the engine functions as the protector of the machine by absorbing the heat. Heat engine is produced by fuel in the cylinder. The heat is deliberately created to generate energy, but it will cause excessive heat if it is left unchecked (over heating effect). In order to prevent overheating and keep the machine temperature, then it uses radiator. How effective radiator is used can be seen by using a tool called a radiator tester. Therefore, this research was Designed a Trial Radiator (Radiator Tester) Laboratory Scale Which is Completed by Round Handler’s Machine and Regulator Wind Blower on Diesel Engine L 300.This research was done by testing the car L 300 diesel in the field then noted rpm and air speed that blew into the radiator. The process of designing a radiator tester L300 diesel engine laboratory scale were making the framework platform machine, making radiator tester cooling system machine to set up a thermometer in the radiator hose in and out, making a mechanism round handlers machine, making a regulatory mechanism wind blower and installing a trial radiator with round handlers machine and wind blower. The rpm test result and air speed on the field was applied to the radiator tester laboratory scale.From the results of the tests, it showed that there was an increase in value of the effectiveness of the radiator without external airflow to engine speed 1000 rpm and the average value was 0.483. Whereas, there was a decrease on the effectiveness of the radiator when given outside air flow 2.3 m / s at 1500 rpm engine speed, which was 0.63.Keywords: Effectiveness, Radiators, Temperature, Air Flow

Abstract

Manual jackscrew is a lifting device used by automobile drivers when any disorders occur, especially when the automobile tires are deflated. Considering manual jackscrew shape and design, not all people are able to use it easily, especially women. This is the reason of manual jackscrew modification into electric jackscrew.This jackscrew modification is conducted by adding a gearbox and DC motor. The ratio between gearbox input and output is 1 : 44.77 and the DC motor power is 160 Watt – 600 Watt. The electric jackscrew working principle is that rotation from DC motor is reduced by the gearbox and forwarded to screw shaft in the jackscrew. The power source is from the automobile battery. The results of electric jackscrew testing show that time of jacking is 10 seconds for tricycle motorbike, 12 seconds  for Gran Max PU car, and 14 seconds for Mazda Vantrend car,all the data is compared with the data manual jackscrew.Key words: jack, screw, manual, gearbox, DC motor, and electric

Abstract

Binary power plant adalah sistem pembangkitan listrik kedua yang mana fluida panas bumi dimanfaatkan sebagai sumber panas utama pada alat penukar panas. Tujuan dari penelitian ini yaitu merencanakan heat exchanger pada binary power plant kapasitas 100 KW, menghitung dan menentukan dimensi-dimensi tiap komponen dari heat exchanger, mengetahui besar longitudinalstress, circumferential stress dan thermal stress yang terjadi pada heat exchanger. Hasil dari perencanaan yang telah dilakukan menunjukan bahwa dimensi dari heat exchanger yaitu berdiameter 0,5 m, panjang 3,6 m, dan tebal dinding yaitu 9,5 x 10-3 m. Tegangan total yang paling besar yaitu tegangan total arah circumferential yang terjadi pada komponen shell dengan nilai sebesar 163,5 Mpa. Tegangan-tegangan yang terjadi pada tiap komponen lebih kecil dibandingkan nilai tegangan ijin material pada nilai SF 1,5 yang direncanakan. Kata kunci :Binary power plant, Circumferential stress, Heat exchanger, Longitudinal stress, Thermal stress.
