Abstract

The problem that occurs today is that many fuel injection vehicles that use Pertamax are switching to Pertalite for economic reasons. This study aims to determine the difference between the use of pure fuel and a mixture of Pertamax and Pertalite fuels on the power, torque and exhaust emissions produced. This study uses the method of collecting data from pure fuel and combining fuel mixtures from 100% Pertamax, 100% Pertalite and 90% Pertamax 10% Pertalite, 80% Pertamax 20% Pertalite, 70% Pertamax 30% Pertalite The result, the highest torque is at Pertamax 100% 12.34 N.m and Max Power 14.15 Hp. The exhaust gas emission content of pure Pertamax is lower, namely CO 15.3%, HC 458 ppm, CO2 8.4%, and O2 5.95%.

Abstract

Spark plugs are the most important thing in the combustion system. Spark plugs in internal combustion using gasoline significantly affect vehicle performance. Likewise, fuel use must follow the compression ratio in the combustion chamber. The purpose of this study was to obtain the effect of differences in hot, cold, and medium spark plugs on engine performance and also the effect of fuel differences in supporting the performance of pertalite and pertamax two-wheeled vehicles in supporting the performance of 135 CC two-wheeled four-stroke vehicles in 2009. The result with hot spark plugs will maximizer-pm, increasing torque and power with pertalite fuel—the effectiveness of increasing power by 31%.

Abstract

In general, the engine when running must be in a stable condition. So it is necessary to keep the engine temperature cool during operation, this is very important so that performance is maintained and power is not sluggish. One way is to use a cooler, adding STP Cooler to non-coolant water will certainly reduce engine temperature. The purpose of this study was to determine the effect of using STP Cooler on engine temperature when using plain water and a mixture of plain water and STP Cooler. The method used in this study was to test at 3 variations of engine speed, namely 1000 rpm, 1500 rpm and 2000 rpm. The results obtained show that the average temperature of the engine when using plain water at 1000 rpm engine speed is 65 oC, at 1500 rpm engine speed the temperature is 70 oC, and at 1500 rpm engine speed the temperature is 78.3 oC, while the average temperature when using a mixture plain water with STP Cooler at 1000 rpm rotation the temperature is 70.6 oC, , at 1500 rpm rotation the temperature is 75.3 oC, and at 2000 rpm rotation the temperature is 81 oC, . From the test results it can be concluded that when using ordinary water the average temperature is still lower than when using a mixture of ordinary water and STP Cooler.

Abstract

Turbin angin Savonius sebagai alternatif sumber energi terbarukan. Turbin angin Savonius dirancang dengan prinsip kerja yang sederhana, efektif dalam menghasilkan energi listrik pada kecepatan angin rendah, dan mudah dalam perawatan. Tujuan dari penelitian ini adalah untuk merancang dan membuat turbin angin Savonius dengan memiliki efisiensi yang tinggi. Metode yang digunakan adalah metode ekperimental, pengumpulan data, perancangan turbin, pembuatan prototipe, dan pengujian. Pengujian dilakukan dengan mengukur putaran turbin dan menghitung rpm yang dihasilkan pada berbagai kecepatan angin dengan silinder pengganggu dan tanpa silinder pengganggu. Hasil penelitian menunjukkan bahwa desain turbin angin Savonius menggunakan material alumunium 6061 dengan jumlah 2 blade, tinggi blade 500 mm, diameter 722 mm. Pada kecepatan angin rendah 3 – 5 m/s blade dapat berputar untuk menggerakkan generator dan menghasilkan energi listrik, menggunakan power inverter dapat menghasilkan listrik 220 volt. Pengujian tanpa hambatan menghasilkan posisi ideal adalah jarak 0,5 meter dengan kecepatan angin sebesar 4,5 m/s menghasilkan 91 putaran permenit dan 93,7 rpm. Pengujian pengaruh variasi silinder pengganggu menghasilkan jarak ideal posisi silinder pengganggu adalah 20 cm, pengaruh silinder 4 dengan ukuran diameter 85 mm menghasilkan 73 putaran permenit, 91,2 rpm dan pengujian dengan beban generator menghasilkan kecepatan angin ideal dengan kecepatan angin 4,5 m/s dan jarak 0,5 meter menghasilkan 64 putaran permenit, 86,5 rpm dan 9,1 volt .Simulasi blade displance atau perubahan bentuk pada saat terkena angin menghasilkan nilai maksimal 0,07548 mm dan simulasi blade mises stress atau beban titik tumpu dengan nilai maksimal 3,561 MPa. Dari simulasi fluid dengan kecepatan angin 4 m/s dengan streamline 3,8 s/d 5,8 m/s.

Abstract

Technology can be used as a preventive measure to avoid theft. One technology that can interfere and even make the perpetrator cancel the robbery is an alarm. With the sound of the alarm, the thief can be surprised and will immediately save himself because he is worried about being caught. Until now, various alarm technologies have been studied, from simple to complex. There are also many sensors used as triggers for alarm activation. This study created a simple anti-break alarm that is not easily turned off using a magnetic switch and relay. Several parameters are measured to determine the performance of the input and output of the alarm such as voltage and current, then a consistency test is carried out from the alarm that was created. The results obtained were that the alarm functioned properly. The alarm can sound when the door is opened then continues to sound and does not break when the door is closed again. The alarm also works consistently after 100 tests.
