Abstract

Dalam penelitian ini adapun tujuan yang diharapkan terkait dengan analisis perhitungan head pompa sentrifugal pada rangkaian seri dan paralel yaitu untuk mengetahui perbandingan nilai head total pompa dari dari masing-masing rangkaian, serta untuk mengetahui perbandingan dari hubungan head (m) terhadap bukaan valve dan juga hubungan head loss terhadap bukaan valve. Proses pengujian dilakukan dengan menggunakan dua pompa sentrifugal tipe 1 ½ BA-6 dengan jenis fluida kerja yang dipakai ialah air pada temperatur ±30⁰C. Dari hasil penelitian yang telah dilakukan didapatkan suatu hasil data analisis dari perhitungan head total pompa,  dimana nilai head total pompa seri untuk bukaan katup penuh sebesar 38,79 m dengan debit aliran 0,00325 , bukaan katup 2/3 nilai head total sebesar 46,14 m dengan debit aliran 0,00323  dan bukaan katup 1/3 nilai head total sebesar 50,16 m dengan debit aliran 0,00306 . Sedangkan pada pompa paralel diperoleh nilai head total dari bukaan katup penuh sebesar 27,7 m dengan debit aliran 0,00375 , bukaan katup 2/3 nilai head total sebesar 32,6 m dengan debit aliran 0,00374  dan bukaan katup 1/3 nilai head total sebesar 37,9 m dengan debit aliran 0,00367 . Dari hasil data yang diperoleh dapat diambil kesimpulan bahwa adanya kenaikan nilai head total terhadap variasi pengaturan bukaan valve yang mana nilai head total tertinggi terdapat pada bukaan valve 1/3. Dan dari kedua jenis rangkaian terlihat adanya penurunan nilai head total seiring juga dengan bertambahnya nilai debit/kapasitas pada pompa. Sehingga hubungan antara head total dengan debit adalah berbanding terbalik, dimana nilai head  terendah diperoleh pada debit yang paling besar.

Abstract

Mesin pencoak pipa (pipe notcher) yang ada di pasaran saat ini harganya cukup mahal sehingga banyak bengkel-bengkel kecil masih menggunakan cara konvensional untuk melakukan pencoakan pipa. Cara yang biasa digunakan adalah dengan menggunakan gerinda tangan, sehingga membutuhkan waktu yang lama dan hasilnya kurang presisi. Untuk itu pada penelitian ini dirancang mesin pencoak pipa dengan memanfaatkan sabuk amplas sebagai V-belt yang dihubungkan dengan poros dan digerakkan oleh motor listrik. Kemudian benda kerja didekatkan pada poros matras dan selanjutnya ditekan maju sampai terbentuk profil yang diinginkan. Rancang bangun mesin pencoak pipa multi dimensi ini terbagi dalam tiga tahap. Tahap pertama konsep desain dan perencanaan komponen, dilanjutkan dengan tahap pembuatan dan terakhir adalah pengujian mesin. Dari hasil rancang bangun diperoleh bahwa mesin pencoak pipa multi dimensi ini menggunakan motor listrik 0,5 HP dan putaran 1400 rpm sedangkan rangka mesin menggunakan besi siku ukuran 4 x 4 cm. Setelah dilakukan pengujian, mesin dapat bekerja dengan baik. Untuk mencoak pipa dengan diameter 3/4 inch dibutuhkan waktu selama 0,335 menit, sedangkan untuk pipa ukuran 1 inch membutuhkan waktu selama 1,075 menit. Sedangkan profil yang dibuat menggunakan mesin ini mampu membentuk sudut antara 0° sampai dengan 30°. Pipe notcher on the market today are quite expensive so that many small workshops still use the conventional method for cutting special pipe profiles. The method commonly used is to use hand grinding, so it takes a long time and the results are less precise. For this reason, in this study was designed a pipe notcher machine using the sandpaper belt as a V-belt connected to a shaft and driven by an electric motor. Then the workpiece is brought closer to the mattress axis and then pressed forward until the desired profile is formed. The design of this multidimensional pipe notcher engine is divided into three stages. The first stage is the design concept and component planning, followed by the manufacturing stage and the last stage is machine testing. From the design results, it is found that this multi-dimensional pipe notcher machine uses an electric motor 0.5 HP and a rotation of 1400 rpm while the engine frame uses 4 x 4 cm angle iron. After testing the machine can work properly. To check a 3/4 inch pipe it takes 0.335 minutes, while for a 1 inch pipe it takes 1.075 minutes. Meanwhile, the profiles made using this machine are capable of forming angles between 0 ° to 30 °.

Abstract

The purpose of this study was to determine the characteristics of the two centrifugal pumps using the same circuit and to obtain the resulting value, namely head, discharge, pump power, efficiency of the two pumps. And variations in valve opening settings used are full valve openings, valve openings 2/3, and valve openings 1/3 which have different coefficients at each valve opening. This research method was carried out experimentally. The fluid used is water, fluid pressure measurement using a pressure gauge to measure the pressure side (discharge) and a vacuum pressure gauge to measure the pressure which is relatively lower than the atmospheric pressure for the pump on the suction side (suction) and using a flow meter to determine the volume or discharge water used. The results of this centrifugal pump test equipment research found that the working pump shows that the resulting discharge affects the head value, pump power, and pump efficiency obtained, the higher the total head value, the smaller the resulting discharge. However, this centrifugal pump test equipment can be used for fluid practicum activities in the mechanical engineering department in the mechanical laboratory.

Abstract

The Covid 19 pandemic makes the need for a washbasin in a public place to prevent the spread of the virus. However, in practice the available washbasins are still not standardized and not ergonomic. So that in this study an ergonomic washbasin design was tried using the DFMA (Design for Manufacture and Assembly) method. Because using the DFMA method aims to improve the design. Through this method, it is possible to produce products with a shorter time and the number of components that are more effective in accordance with the function but have better design quality. In this study there were several components that were repaired, combined and removed, but did not change the function and usability of these components. So that this research resulted in a sink design that is modern, multifunctional, easy to use and comfortable.
