Abstract

This study aims to determine the inner surface morphology of pipes and to identify pipe corrosion products using stereo microsocope and X-ray diffraction (XRD) observations. In this study, the sample used was a piece of Blacksteel gas pipe that had been used for 107 days and 570 days with dimensions of 3 cm in length and 4 cm in diameter. The sample was taken from the Air heater Unit of the Pagotan Madiun sugar factory, East Java, Indonesia. Morphology the inside of the tube was observed with a CARL ZEISS Stemi DV4 stereo microscope (32x magnification). Furthermore, the rust material powder on the sample pipe was taken to determine the corrosion product using the XRD X'Pert PRO instrument. The results of observation by using a stereo microscope on the inner surface of air heater pipe that had been used for 107 days and 570 days indicated that the pipe surface experienced corrosion and peeling. From the results of X-ray diffraction (XRD) observations, FeOOH layer were formed from Fe2+ and OH- ions produced from O2 and H2O molecules in the smoke gas from burning bagasse. At the bottom of FeOOH layer, Fe3O4 was formed from the subsequent reaction between FeOOH and Fe2+ ions.Keywords: pipe, air heater, corrosion, smoke gas.

Abstract

From the development and progress of a country, increasing the speed of growth, and increasing speed, from that we need a word to reduce exhaust emissions produced by motors because the catalyst is made of copper and it is easy for us to get the basic materials and for the manufacture of the catalyst is also a little easy. Its utilization is to reduce HC and CO gases from incomplete combustion of motorized vehicles and fuel mixed with ethanol which slightly helps to increase the combustion of motor vehicles. Seen from the CO results from the use of full hole catalyst, it is 2.7490, in the right hole is 2.4650 and the left hole is 2.6290. seen the results of HC from the use of the full hole of 597.30, on the right hole of 492.60 and the left hole of 637.70.

Abstract

A locomotive is one of critical part in train set, because a locomotive had to bear a big load and has operational time which long enough. So in a locomotive design required more in depth analysis compared to the other means of transportation. The purpose of this research is to make a design locomotive carbody according to those standards applied and analyze stress happened to carbody locomotive designed. In the design of this to analyze carbody locomotive construction strength, the analysis are done using finite element methode(FEM) with help of Ansys software. The simulation of loads working on the structure was made approaching the real loading. Structure of locomotive carbody should be able to hold the loads working on carbody construction. From the design results locomotive carbody that have been made, this locomotive carbody sized length 19000 mm, width 2790 mm, and high 3700 mm. Materials that used for the locomotive carbody design isSS 400 and SM 490A with Yield stress of 245 MPa dan 325 MPa. The analysis results received a value of von mises stress maximum of 195,429 MPa that occurs at the part of the end of underframe (end center sill), where the sress value are still below of Yield stress materials which are in the form of SM 490 at 325 MPa. From the analysis result suggests that overall locomotive carbody structure can be expressed as safe and able to hold the loads operational.

Abstract

Plastic oil is a fuel produced from plastic, which is processed by means of distillation. In the plastic distillation process used LDPE (Low density polyethylene) plastic bag, this type of plastic is ductile and flexible in addition to this type of plastic also has a transparent nature, and is resistant in shock so that this type of plastic is widely used by the community for plastic wrapping. LDPE plastic is included in the type of thermoplastic is one of a group of plastics that are able to be recycled again so that it is easy in the distillation process. The results of diesel oil plastic types will be mixed with bio diesel and tested for density, color, distillation, flash point, sulfur content and cetane number values. In a mixture of 30% LDPE plastic type diesel oil and 70% bio diesel with a density of 843.3 kg / m3, has a clear and bright color, in the distillation process in a mixture of 30% LDPE plastic type diesel oil 70% bio diesel is known at initial temperatures IBP 150oC at 10% drop at 201oC at 50% drop at 289oC and at the last drop 90% at 347oC. a mixture of 30% LDPE plastic type diesel oil and 70% bio diesel has a flash pont value with 57oC test results. sulfur content in a mixture of 30% LDPE plastic type diesel oil and 70% bio diesel with a value of 0.11% m / m, in a mixture of 30% LDPE plastic type diesel oil and 70% bio diesel has a cetane number value of 53oC.

Abstract

Plastic oil is the result of the conversion of plastic waste into fuel oil. The use of plastic waste oil is not directly at 100% use, but it is necessary to have the right dose so that it can be used as a mixture. The method used in this study is experimental research, namely several variations that are carried out successively to the same subject and determine the performance and exhaust emissions on a motorcycle with a mixture of Pertamax and plastic oil and has a CP10 code (pertamax 90% + plastic oil). 10%), CP20 (pertamax 80% + plastic oil 20%), and CP30 (firstmax 70% + plastic oil 30%). The results of all tests of the highest torque occurred in the CP30 mixture of 14,593 Nm at 3000 rpm and the highest power results in the CP30 mixture of 7.1 Kw at 5000 rpm. In the test results the best CO exhaust emissions occurred in the CP10 mixture with emission levels of 1.69% at 5500 rpm while the best HC exhaust emission test results are in the CP10 mixture, which is 81 ppm at 5500 rpm. The lower the CO and HC exhaust gas emission levels, the more efficient the fuel and the more complete combustion.

Abstract

Salah satu upaya untuk memperlancar pemasukan campuran bahan bakar ke dalam silnder yaitu dengan cara memodifikasi venturi karburator. Karena pada saat langkah hisap, campuran bahan bakar tidak terhisap seluruhnya, sehingga perlu dimodifikasi dan sekaligus untuk mengetahui perubahan performa mesin. Untuk mengetahui hasil dari perubahan venturi pada karburator akan dilakukan pengujian dengan menggunakan dynamometer chasis, dimana torsi dan daya didapat dari roda belakang. Pengujian dilakukan dengan beban tetap, data di dapat dari rol yang diputar roda listrik, dan data diambil dari terendah 5000 rpm sampai yang tertinggi atau full open throttle pada gigi transmisi 3, untuk konsumsi bahan bakar data diambil dari rpm 5000, 6000 dan 7000, sedangkan untuk emisi gas buang diambil pada putaran mesin stasioner. Dan masing masing benda uji diuji sebanyak 5 kali. Pengujian dilakukan di laboratorium Mototech Indonesia Yogyakarta. Hasil pengujian pada dynamometer menunjukan torsi, daya, konsumsi bahan bakar dan kadar CO pada emisi gas buang dapat diketahui setelah venturi dimodifikasi. Data torsi tertinggi ditunjukan pada modifikasi 17 mm sebesar 7,36 Nm pada rpm 5750. Data daya tertinggi ditunjukan pada modifikasi 17 mm sebesar 6,0 hp pada rpm 6000. Berdasarkan perhitungan konsumsi bahan bakar untuk kondisi standar maupun modifikasi, konsumsi bahan bakar terendah ditunjukan pada modifikasi 17 mm sebesar 0,3 ml/s pada rpm 5000 sedangkan konsumsi bahan bakar tertinggi ditunjukan modifikasi 18 mm sebesar 0,583 ml/s pada rpm 7000. Berdasarkan pengujian pada gas analyzer menunjukan CO terendah 6,20 % pada modifikasi 17 mm, dan CO tertinggi 9,19 % pada modifikasi 18 mm.

Abstract

Ketergantungan akan energi listrik terus meningkat dan ketersediaan energi fosil saat ini mengalami penurunan maka diperlukan sumber energi baru yang terbarukan dan ramah lingkungan. Salah satu energi yang dapat dimanfaatkan adalah energi angin. Tujuan penelitian ini adalah untuk mendapatkan unjuk kerja model turbin angin Savonius tipe L dengan 3 variasi. Ketiga variasi turbin angin tersebut dibuat dalam tiga stage, dengan ukuran yang sama yakni 0,35 m x 0,60 m.. Setiap model turbin angin diuji untuk mengetahui torsi, putaran poros, daya kincir, TSR dan koefisien daya. Hasil penelitian menunjukkan bahwa model turbin Savonius dengan jumlah 2 stage memberikan koefisien daya (Cp) maksimal (21,86 % pada kecepatan angin 8,57 m/s) tertinggi di antara ketiga model turbin yang diteliti. Model turbin angin Savonius dengan bentuk sudu standar menghasilkan koefisien daya maksimal 14,10 % pada kecepatan angin 7,92 m/s. Serta turbin angin ketiga menghasilkan koefisien daya sebesar 16,39 % pada kecepatan angin 8,7 m/s
