Abstract

This study aims to develop an analog compression tester measuring instrument into a digital compression tester as a measurement tool that can provide effectiveness and efficiency to users. This research is a research and development or R&D. This research was conducted in several steps, namely: problem identification, information gathering, product design, product manufacture, expert validation, product revision, testing, final production. The development of analog compression tester was first validated by material experts, media experts, and 15 students, and 5 students for field trials. The subjects of this study were vocational students at Taman Karya Madya Teknik Kebumen. Data collection techniques used in this study using instruments in the form of a questionnaire. The data analysis technique of this research is descriptive qualitative and quantitative descriptive percentage. The results of the development of digital compression tester designs are: 1) the tools and materials used are electric drill, grinding, cutter, goggles, gloves, masks, ruler, acetaminine welding, screwdriver, scissors, digital dial pressure gauge, hose, spark plugs, clamps , and nepel, 2) the manufacturing process that starts from the cutting process, the hole drilling process, the welding process and the process of connecting between components, 3) the workings of digital compression tester design that is reading the pressure or compression of the machine displayed on the monitor digitally using dial pressure digital gauge, 4) the test results obtained from the validation results from: a) material experts at 89% or Eligible; b) media experts at 85% or reasonable; c) response of field trial students in terms of ease of use and reading of 90% or feasible. Thus, the conclusion that the digital compression tester measuring instrument declared feasible to use for measurement.

Abstract

Pengujian sirkulasi pada trainer simulator air conditioning mobil bertujuan untuk menguji media pembelajaran simulator sistem air conditioning mobil dengan perantara bahan plastik sebagai bilik kondisi ruangan tertutup pada praktikum mata kuliah sistem air conditioning mobil. Metode penelitian yang digunakan adalah metode penelitan deskriptif dan dokumentasi. Untuk memperkuat hasil penelitian yang memiliki relevansi yang erat dengan pokok permasalahan maka pengambilan data dengan cara observasi dan studi kepustakaan. Hasil pengujian pada trainer simulator air conditioning pada menit ke-20 yaitu: 1) kecepatan putaran blower tinggi suhu kabin rata-rata 17ËšC, 2) Kecepatan blower sedang suhu kabin di bawah 17ËšC, dan 3) Kecepatan blower rendah rata-rata suhu kabinnya 20ËšC.

Abstract

The purpose of this research is to get a clear picture of the process of reconditioning and testing the 1984 Toyota Rino diesel engine. And to find out which components must be renovated for excellent engine performance. This research was conducted at the Piksi Ganesha Polytechnic Laboratory of Indonesia. The research method used is qualitative. The result of the reconditioning process is that several diesel engine components must be replaced in gaskets, air, and fuel filters. The results of testing the diesel engine Toyota Rino 1984 are: 1) Injector test, all injectors’ functions should run when tested using a pressure nozzle test; namely, the manometer shows 3000 psi when the lever is pressed, the nozzle can spray fuel tightly, and the nozzle does not leak; 2) Compression test, all cylinders are still in good condition when tested using a cylinder pressure tester, namely the manometer shows the number 30 kg/cm2.
