Abstract

Magnetic induction welding is a common process in pipe production. The impeder used in the welding machine needs to be cooled to maintain its temperature below 35oC. The cooling fluid is water with 2% cutting oil and called coolant. It should enter the impeder at 15oC. The required flow rate is as much as 30 lt/min. To ensure the impeder’s temperature be kept lower than required temperature, then the heat exchanger shall be designed to cool the coolant from 40oC to 15oC. Air-cooled water chiller type UWAP750AY3 is used to produce chilled water needed by the heat exchanger. The 5/8-inch-finned-copper pipes are used as tubes in the heat exchanger. The coolant is divided in four equally tubes from a header. To meet the heat transfer area needed, each tubes will be bent to make 10 passes (or rows). At the end of the last row, four flow will be gathered in a header. Then, the coolant will circulate to impeder with the required temperature. Numerical simulation was conducted to get the velocity vector and temperature distribution of flow inside the tube, and also the pressure drop of the flow across the tubes and header. Velocity vector of flow around return bend, flow in entrance and exit are interesting. They give understanding that the pressure drop will be higher in such accessories than in straight pipe. The pressure drop of coolant flowing inside tubes of heat exchanger is 5143.2 Pa from analytical solutions and 4611.4 Pa from numerical simulation using Fluent. Temperature of coolant at outlet got from numerical simulation is almost the same with the designed temperature, i.e. 15oC. So, the numerical simulation reinforces the design of the heat exchanger.

Abstract

In this paper, writers create a new design of reusable plastic bottle, which can reuse as building bricks called Rubicks v. 2.1 with some upgrade of the design that can reinforce static strength when the body of bottle applied by a force. The purpose of this research are to find and to analyze the magnitude of force that can make the design of bottle will be fail or damage. The method that used in this paper is Finite Element Method (FEM). In this paper, the bottle given ten of variation magnitude of forces from 200 N to 2000 N. The result and analyze that the lowest total deformation value is 0.22 mm and the highest total deformation value is 2.25 mm. For Maximum Shear Stress, the lowest maximum shear stress is when the bottle applied 200 N each is 3.66 MPa. Meanwhile, the highest maximum shear stress is when the bottle is applied 2000 N each is 36.65 MPa. The most effective of safety factor is chosen when the bottle have a value of safety factor equal or more than 1. The magnitude of force that can applied on the Rubicks v. 2.1 plastic bottle design is 1700 N.

Abstract

Data kesehatan tahun 2012 menunjukkan bahwa 2,45 % dari jumlah penduduk Indonesia merupakan penyandang disabilitas. Penderita tuna daksa menempati posisi kedua setelah gangguan pada penglihatan. Amputasi bawah lutut adalah salah satu bentuk tuna daksa yang banyak terjadi di Indonesia. Pasien amputasi bawah lutut akan kesulitan berjalan karena ketiadaan organ akibat amputasi. Prostesis bawah lutut merupakan alat pengganti organ bawah lutut. Prostesis bawah lutut akan membantu penderita amputasi bawah lutut agar dapat berdiri dan berjalan. Saat ini, produk prostesis bawah lutut yang ada di Indonesia masih memiliki banyak kekurangan. Pembuatan prostesis masih menggunakan metode custom sehingga membutuhkan proses pembuatan yang lama dan harga yang relatif mahal. Produksi massal tentu dapat menjadi solusi untuk menekan harga dan waktu pembuatan. Desain prostesis bawah lutut yang dapat mengakomodasi rentang antropometri orang Indonesia diperlukan agar prostesis bawah lutut dapat diproduksi secara massal. Hasil pembuatan desain kemudian diuji melalui simulasi sesuai standar ISO 10328 sebelum pembuatan prototipe dan produksi. Prostesis bawah lutut tersebut dirancang untuk mampu menahan beban 100 kg dengan safety factor 4. Selain itu, prostesis bawah lutut yang telah dirancang dapat digunakan untuk penderita yang memiliki rentang tinggi badan antara 150 cm hingga 180 cm.

Abstract

The generator generate optimum electrical energy if drive system sends the power from turbine to generator with the direction of rotation and speed as needed. The object of this research, how to design spur gear transmission apply for pico hydropower. There are several point to design spur gear transmission, i.e. the bending stress and contact stress on the teeth, and shear stress on the shaft. The strength of the tooth and shaft, simulation using by Ansys Workbench 14.5. Materials used to manufacture gears is polyamide 6 and the shaft material is teflon. Furthermore if design allowable the process of manufacture can be begin, and if manufacture finished, carried testing transmission on the pico hydropower prototype. The result of this research are the design spur gear transmission have total gear ratio 1: 2.65 with two pairs of gears each 1:1.73 and 1 : 1.52. Simulate using by Anys Workbench 14.5 shows the value maximum bending stress 6,1453 MPa on the gear driven first mate, the contact stress 15,415 MPa on the gears driving first mate, and shear stress 1,7688 MPa on the output shaft. Experimental test show the gear transmission produce electric power higher than the electric power produced by direct transmission.

Abstract

Especially at this time in big cities like jakarta is certainly a lot of society for various commodities every day .Similarly , the amount of waste generated every day reaches ± 6000 tons which is dumped into bantar gebang tpu , and among of the waste 13 % -14 % is plastic type , not to mention not picked up by scavengers .It is better to use this waste to be a useful compared to the habits of people who as often as burn garbage .Burning waste will make water pollution especially if plastic waste .In this study made fuel oil sourced from plastic using gasification and distillation method that will convert gas from plastic into oil .From the results of this study found that the resulting plastic oil is close to the an element of of diesel oil .The amount of oil produced from each kg of plastic raw material produced 570 ml of plastic oil .This oil is close to the type of diesel oil

Abstract

Currently, the human need for energy is growing larger, due to the increasing population. The dependence on fossil fuels can be seen from Indonesia’s energy usage. Nowadays, energy consumption is dominated by petroleum (46.9%), natural gas (21.9%), coal (26.4%), and other (4.8%). Therefore, to reduce dependence on fossil fuels, biomass can be used as alternative energy which is renewable. In addition, technology required to improve the combustion efficiency is necessary. To convert solid fuel into gas fuel is gasification process. In this research, the downdraft gasification type reactor was tested. In this test, results obtained are CGE (Cold Gas Efficiency) by 41.1% and the gas content of CO2 (2.98%), H2 (2.66%), N2 (66.99%), CO (15.71 %), CH4 (2.98%), H2S (0.15%) with an AFR of 2.47
