Abstract

During the workpiece turning process, several factors affect the final workpiece, such as the cutting angle and cutting speed. The purpose of this study was to determine the effect of variations in cutting angle and cutting speed on the material consumption rate of SCM 440. The method used in this study is the Response Surface Methodology (RSM), with a two-parameter design, each of which has three levels for each parameter variation. . The results of data analysis obtained eigen values ​​with different signs (positive and negative) which indicated that the stationary point values ​​were in the form of saddle points with a stationary point values of x1 (cutting angle) of -1.686 and x2 (Vc) of 0.199. From the uncoded process, the optimal value for the MRR factor is obtained, namely the cut angle of 10.64° and Vc of 15.28 m/min. The optimum feed rate for SCM 440 material is obtained at an optimal value of neither minimum nor maximum or a saddle point shape at a cutting angle cut of 10.64° and Vc of 15.28 m/min with an MRR area of ​​300-400 mm3/minute.

Abstract

The success of the manufacturing world in improving production processes is greatly influenced by the machine equipment used. SKD-11 steel has high wear resistance and good ductility, so it is suitable for components that require high precision and durability. Surface Response Method (RSM) Box-Behnken Design can be used in the optimization process, which has three variables that can predict the best optimum value. The roundness variable used in this research is MZC (Minimum Zone Circle), whose non-roundness value is the difference between the radius of the most extensive circle profile and the smallest circle profile, MZC. From the test results, it was found that the smallest non-sphericity was 7.5 μm. The optimal value for this test is VC 234.784 m/minute, feeding 0.127 mm/rev and depth of cut 0.18 mm, and the predicted response value is 13.05 μm. From the results of the ANOVA analysis, these three factors have no effect on roundness, but there is one factor that almost influences roundness, namely the depth of cut.

Abstract

Produk cacat dalam produksi bata ringan dapat menyebabkan dampak negatif tidak hanya pada biaya keuangan, tetapi juga pada efisiensi produksi, reputasi perusahaan, dan aspek bisnis secara keseluruhan. Produk cacat mengakibatkan pemborosan bahan baku seperti semen, pasir, foam, dan air, serta energi yang telah digunakan dalam proses produksi, seperti pencampuran, pencetakan, dan pengeringan. Penelitian ini bertujuan untuk mengurangi tingkat cacat produk dengan memodifikasi mesin potong bata ringan dari tipe sumbu X menjadi tipe sumbu X-Y. Mesin potong tipe sumbu X hanya mampu memotong pada satu sumbu, sedangkan tipe sumbu X-Y dapat memotong pada dua sumbu secara simultan. Desain penelitian menggunakan eksperimen komparatif antara dua mesin dengan variabel bebas berupa jenis mesin, dan variabel terikat berupa jumlah cacat produk dalam satu siklus pemotongan. Pengamatan dilakukan selama lima siklus untuk setiap mesin. Data dikumpulkan menggunakan formulir khusus dan dijaga konsistensi variabel lain seperti bahan baku dan jumlah pekerja. Analisis data meliputi uji normalitas (Kolmogorov-Smirnov) untuk memastikan distribusi data, dilanjutkan dengan uji t untuk membandingkan jumlah cacat antara kedua mesin. Hasil analisis menunjukkan bahwa modifikasi mesin potong menjadi tipe sumbu X-Y secara signifikan menurunkan jumlah cacat produk, sehingga meningkatkan efisiensi dan kualitas produksi bata ringan. Analisis dilakukan menggunakan software Minitab untuk memastikan keakuratan hasil. Hasil analisis menunjukkan bahwa modifikasi mesin potong berhasil menurunkan tingkat cacat secara signifikan, memberikan manfaat nyata terhadap efisiensi dan kualitas produksi bata ringan.

Abstract

Limbah cair industri makanan umumnya menghasilkan cairan yang mengandung pH rendah. Air limbah tersebut dialirkan ke sungai sehingga air tercemar dan menjadi asam. Air dengan pH yang rendah tersebut dapat diperbaiki kualitasnya dengan menambahkan adsorben. Cangkang siput gonggong dapat digunakan sebagai adsorben dengan cara aktivasi. Aktivasi berguna meningkatkan muatan adsorpsi, sehingga energi adsorpsinya bisa dinaikkan. Proses aktivasi dilakukan menggunakan oven dengan temperatur 550°C, 650°C, dan 750°C. Serbuk yang digunakan adalah mesh 100, 150, dan 200. Metode analisis untuk mengetahui nilai optimal proses aktivasi sehingga menghasilkan karakter kualitas terbaik digunakan metode Taguchi. Hasil penelitian menunjukkan bahwa serbuk siput gonggong yang telah diaktivasi dapat meningkatkan pH air yang tercemar. Hasil optimasi dengan metode Taguchi diketahui bahwa nilai terbaik temperatur aktivasi berada pada suhu 550°C dengan ukuran serbuk mesh 150 (± 89 μm).

Abstract

Tin mining tailings consist of 80-90% sand and the rest mud.  The high levels of Silicon Dioxide (SiO2) in these tailings are hard and can be used as an added material in the manufacture of composites.  This research aims to study the physical and mechanical properties of metal matrix composites reinforced with SiO2 powder processed by powder metallurgy, as an effort to provide a replacement material for Non-Asbestos (NOB) motorbike brake linings.  The impact of hot compaction pressure in the form of two pressing directions, including 4600, 4500 and 4400 Psi, with a pressing hold of 15 minutes and sintering which includes 30, 20 and 10 minutes, at a temperature of 600 ºC was studied for its effect on hardness and density.  Mechanical blending was used with a horizontal ball mill in the ratio of 10:1 at a speed of 90 rpm for 4 hours.  The test results showed that the greater the hot compaction pressure and the longer the sintering, the higher the hardness and density values.  The highest hardness reached 81.7 HB and the highest density of 2.385 g/cm3 occurred at a bidirectional hot compaction pressure of 4600 Psi, with the lowest wear rate of 0.333 mm3/m. This occurs as a result of the increase in hot compaction has an impact on increasing the contact between powder particles resulting from mechanical alloying to be tighter as a result of which the cavity and porosity decrease
