Abstract

AbstrakVacum Forming is process packaging in industrial, wich one deformation of plastic and formed on mold with difference preassure. In food and drinking industrial show positive progress and make bigger contribution for economic grow in Indonesia. At this moment Vacum Forming industrial in Indonesia is just owned big industrial wich have good purchasing power tools in range hundreds of million to billions of rupiah. Metrologi dan Cetak Plastik laboratory in Teknik Mesin Politeknik Negeri Semarang one of the topics is Vacum Forming. Equipment Used is very simple, manny time try and erors needed for have good product without any defects by way temperature varible, pressure, warm-up time and forging. The most difficult is warm-up process where must tu set the hight temperature waring and gap between the material and the heater. The purpose of the research is to know the influence of warming temperatures, time of warming, thick of plastic and pressure on the quality, The result of this research the best variable is time for warm-up 135 second, time of forging 40 second. Ticknes variable is 0,5 mm, 0,3 mm and 0,25mm, the best ticknes of plastic is 0,25 mm.

Abstract

Bahan bakar jenis premium masih menjadi banyak incaran konsumen kalangan menengah kebawah, bahan bakar premium memiliki nilai octane paling rendah, daya yang dihasilkan juga paling rendah dari bahan bakar jenis pertalit dan pertamax. Banyak kalangan berlomba untuk mencari cara bagaiman meningkatakan efisiensi dalam pemakaian bahan bakar jenis premium. Pemanasan mula bahan bakar merupakan salah satu cara untuk meningkatkan efisiensi dalam proses pembakaran, dengan pemanasan mula pada bahan bakar mampu membuat partikel bahan bakar cepat untuk menguap. Tujuan dalam penelitian ini adalah untuk mengetahui pengaruh variasi pemanasan bahan bakar melalui upper tank radiator terhadap daya mesin pada mesin Suzuki SJ410. Variasi yang digunakan adalah bahan bakar tanpa pemanas, bahan bakar dengan panjang pipa 450 mm, dan 900 mm dengan diameter pipa 6 mm. dengan putaran mesin 2500 ”“ 5400 Rpm. Metode yang digunakan untuk mengolah data adalah dengan One-Way Anova. Hasil penelitian menunjukkan bahwa ada perbedaan yang signifikan penggunaan variasi pemanasan bahan bakar terhadap daya pada mesin Suzuki SJ410 dengn daya tertinggi sebesar 29,90 HP pada 4500 RPM dengan panjang pipa 900 mm.

Abstract

AbstractMeans of transportation is one of the needs to make the movement from one place to another. One of the commonly used transportation is motorized vehicles that run on gasoline. Fuel consumption affects the power generated as well as the costs incurred and the time required by motorized vehicles to carry out their functions. This research method uses true experimental design research to conduct performance tests using a Suzuki SJ410 motorized vehicle with an F10A type engine and a capacity of 970 cc.  The test was carried out by carrying out the treatment of heating premium fuel through a copper pipe that was installed on the radiator upper tank with a length of 450 mm (MOD 1) and 900 mm (MOD 2) and also under standard conditions (STD). The results obtained stated that fuel consumption under standard conditions (STD) fuel consumption for 26.03 s/50 ml, for a pipe length of 450 mm (MOD 1) for 31.90 s/50 ml and for a pipe length of 900 mm ( MOD 2) for 33.27 s/50 ml.
