Abstract

Penerapan prisip-prinsip mekanika fluida dapat dijumpai pada bidang industri, transportasi dan rumah tangga. Rangkaian pipa PVC yang digunakan untuk mendistribusikan air di rumah, tentunya memiliki kerugian- kerugian yang diakibatkan oleh komponen-komponennya, salah satunya pada perubahan penampang pipa. Salah satu kerugian energi pada perubahan penampang pipa yaitu penurunan tekanan. Penurunan tekanan dapat dipengaruhi oleh debit aliran fluida dan besarnya perubahan pipa tersebut, dibit memiliki aliran fluida yang mengakibatkan tekanan pada dinding pipa. Penelitian dalam skripsi ini dilaksanakan di laboratorium Teknik Mesin Universitas Hasyim Asy’ari. Penelitian ini bersifat kuantitatif yang akan membahas tentang penurunan tekanan pada perubahan penampang mendadak yang memiliki diameter 1 inci ke ¾ inci dan 1 inci ke 1 ¼ inci ini dengan variasi bukaan katup 100%, 75% dan 50%.Hasil Penelitian penurunan tekanan perubahan penampang pipa 1 inci ke ¾ inci pada setiap bukaan katup yaitu 100% sebesar 0,1 bar, 75% sebesar 0,09 bar dan 50% sebesar 0,05 bar, sedangkan penurunan tekanan perubahan penampang 1 ¼ inci pada setiap bukaan katup yaitu 100% sebesar 0,03 bar, 75% sebesar 0,03 bar dan 50% sebesar 0,06 bar.

Abstract

Renewable energy is energy that can replace fossil energy that will run out, renewable energy sources can come from the sun, water, geothermal, biomass and wind. Based on this explanation, the researchers conducted research on the conversion of wind energy into electricity by making ODGV wind turbines, for the purpose of this study was to find out how the number of blades and the load affect the performance of ODGV type wind turbines. The type of research that the author uses is quantitative research, in this method the author conducts research using a total of 7 blades and variations in lamp load 0, 3, 6 and 9 watts. The analyzed values ​​include voltage, current and revolutions per minute. From the results of the study, it was found that the ODGV wind turbine with a total of 7 blades produced a maximum value, namely, a voltage of 10 volts, a current of 0 watts and an RPM of 280.4 with a lamp load of 0 watts.

Abstract

Right now using of electrical energy in society is increasing. This is reason in doing the work, peoples using tools machine that required voltage source as driver. The explanation to be basic for research about convertion of wind energy to electrical with making vertical axis wind turbine. The aim is find out effect of lamp load to voltage, current, and RPM on the 2 blade savonius wind turbine. This is a experiment research. This research using quantitative descriptive analysis, with independent variables are lamp load 0, 3, 6, 9 watts and the dependent variables are voltage, current, and RPM. Results obtain from testing then analysis and conclusion attract. Results research show highest performance of savonius 2 blades wind turbine on 0 watt lamp load it producting, 11.68 volts, 0 ampere, and 334.2 RPM. Lowest performance of 2 blades savonius wind turbine on 9 watt lamp load producting, 7.68 volts, 0.13 amperes, and 272.9 RPM. Based of results on the test can concluded that, The more lamp loads activated, voltage and RPM values decrease while, current value increases. This is because number of lamp loads increas then, amount electric charge moving per unit of time also increas.

Abstract

Alternative energy is a source of energy found in nature that can be directly used freely. In addition, the availability of alternative energy is infinite and can be managed sustainably. This wind energy source can be used as an electricity generator by building several wind turbine units. The problem in this research is how the influence of the load on the performance of the 8 blades cross flow wind turbine, while the purpose in this study is to find out how the load on the performance of the blades of 8 blades. The type of research I use is quantitative research. For the author's method using an experimental method, the free load variable lights 0, 3, 6 and 9 watts and the dependent variables are current, voltage and RPM. The results showed that the 8 blades cross flow wind turbine had the best performance at 0 watt load which produced 0 ampere current, 13.8 watt voltage and 354.92 RPM. while the lowest performance on a 9 watt lamp load which produces a current of 0.2088 amperes, a voltage of 9.08 volts and Rpm 301.08, the current has increased, this is because the current is directly proportional to the load power, while the voltage and RPM have decreased because generator voltage and RPM are inversely proportional to the load power used.

Abstract

Kondensor merupakan suatu alat yang berfungsi sebagai pendingin pada alat pirolisator yang menggunakan bahan dasar limbah plastik bertipe LDPE. Pipa yang terdapat dalam kondensor berbahan dari tembaga dan kuningan yang berbentuk spiral atau melilit. Pada penelitian ini menggunakan kondensor dengan pipa tembaga Ø8 mm dengan panjang 1000 mm dan 2000 mm. Penelitian ini menggunnakan metode penelitian eksperimental untuk menguji kondensor terhadap hasil minyak, Hasil yang diperoleh dari pengujian kondensor dengan 1 kg plastik jenis LDPE yaitu volume minyak tertinggi pada pipa tembaga Ø8 mm dengan panjang 2000 mm menghasilkan 400 ml. Penelitian ini menggunakan pengolahan data ANOVA 2 jalur, hasil yang diperoleh dari hasil volume minyak yaitu nilai sig. 0.000 menunjukkan terdapat pengaruh signifikan terhadap hasil volume minyak, hal ini menunjukkan terdapat pengaruh signifikan terhadap volume minyak.
