Abstract

The main challenge in the briquette-making process is selecting the appropriate and proportionate reinforcement or adhesive. The chosen adhesive must not only provide strong adhesion but also be compatible with other components. Briquettes are alternative fuels in solid form, made from carbon-containing materials with a high calorific value, allowing them to burn for an extended period. Coal is one of the alternative materials that can be used for briquettes. The choice of adhesive type and composition directly influences the compressive strength, thermal stability, and durability of briquettes in various environmental conditions. This study aims to investigate how process parameters affect the compressive strength of briquettes produced from coal powder reinforced with molasses, to improve the efficiency of the briquette production process. The methodology used in this study is the Taguchi method. The process parameters include four factors, each with three levels, tested with three replications: the percentage of reinforcement or adhesive at levels of 10%, 12.5%, and 15%; pressure at levels of 8 MPa, 10 MPa, and 12 MPa; temperature at levels of 70 °C, 90 °C, and 110 °C; and heating time at levels of 60 minutes, 90 minutes, and 120 minutes. To enhance the comprehensiveness of the study, several factors, including the moisture content of the briquettes, have also been examined. The results indicate that the temperature during the drying process is the most significant factor influencing the production of these briquettes.

Abstract

The safety aspect is important that must be considered in vehicles, because components that not comply with standards can pose serious risks. The use of asbestos also have a negative impact on health, caused by exposure to contaminated air and can damage respiratory system. This research aims to develop environmentally friendly brake linings, as well as studying the effect of two-way hot compaction pressure and reinforcement volume percentage on friction coefficient. This research uses powder metallurgy method which starts from the process mixing recycled aluminium powder, silica sand, and palm oil boiler fly ash, using ball mill machine (BPR 10:1) at speed 90 rpm, for 6 hours. Compaction was carried out in two directions with pressure variants of 5000, 5400 and 5800 Psi at temperature 350°C for 10 minutes. The sintering process was carried at temperature 600°C with holding time of 10 minutes. Friction coefficient testing is carried out to calculate the wear by following the ASTM G99-05 standard. The results show that increasing the percentage reinforcement and compaction pressure can increase friction resistance, highest wear value of 0.055 gr with parameters (84% reinforcement, pressure 5000 Psi) and the lowest wear value of 0.032 parameters (92% reinforcement, pressure 5800 Psi).

Abstract

This study aims to analyze the effect of process parameters on the Material Removal Rate (MRR) in CNC milling machining of S50C steel material. The process parameters examined include spindle speed (RPM), cutting speed (Vc), and depth of cut. The experimental design uses the Taguchi method with an L9 (3³) Orthogonal Array matrix, including three repetitions to ensure data reliability. The analysis results show that the depth of cut has the most significant impact on increasing MRR, contributing 86.14%. The optimal MRR value is achieved with the process parameter combination of spindle speed at 3,184 rpm, cutting speed at 105 m/min, and depth of cut at 0.6 mm. Selecting the appropriate process parameters can enhance the efficiency of material removal in CNC milling machining. This research provides guidance for practitioners to determine optimal parameters to achieve maximum results in material processing.

Abstract

This study aims to investigate the effect of the percentage of reinforcement and hot compaction pressure on the density value of Aluminum Matrix Composite brake pads, reinforced with Boiler-Fly-Ash and silica sand. The Powder Metallurgy method was used in this study, with variations in the weight fraction of reinforcement being 6%, 10%, and 14%. Mixing of the matrix powder and reinforcement was performed using a Ball Mill Machine, with a Ball Powder weight Ratio of 10:1, within 6 hours of mechanical alloying at a speed of 90 rpm. The molding process used a hot compaction system in the form of a Hydraulic Jack machine with an upper press and a lower press, with a hot pressing temperature of 350 ºC, a holding time of 10 minutes, at a pressure variation of 5200 Psi, 5600 Psi, and 6000 Psi. The sintering process used a temperature of 600 ºC at a holding temperature of 10 minutes. The density test of the specimen uses the ASTM B962-17 standard with the Archimedes theory approach, while the hardness test uses the Brinnel Hardness, referring to ASTM E110-14.  The result, the highest average density value is 2.10 g/cm³ with a reinforcement percentage variation of 10%, while the lowest density value is 1.90 g/cm³ with a reinforcement percentage of 14%. The highest hardness value is 42.93 HB with a percentage of 10%, while the lowest hardness value is 41.4 HB with a reinforcement percentage of 14% compaction of 6000 Psi

Abstract

Research on aluminum metal matrix composites reinforced with ceramics using powder metallurgy methods has recently been increasingly in demand to be developed. The goals of this study determined the effect of differences in compaction pressure on the density and hardness properties of the resulting composite. The research method used of is following the stages of the powder metallurgy process, which includes material preparation, mixing and compaction. The mixing of the composite constituent powders was carried out using the mechanical alloying method using a horizontal ball mill for 4 hours. While the hot compaction method used is two-way compression compaction, using a hydraulic pump. The matrix material used is recycled aluminum powder, and the reinforcing material is powder from tin mine tailing silica sand. The hot compaction process was carried out at 500 0C and held for 15 minutes. Two-way compacting pressure variations used 4400 Psi, 4500 Psi and 4600 Psi. Density testing refers to Archimedes with the ASTM B962-15 standard. Meanwhile, the hardness test used the Rockwell hardness testing machine, referring to the ASTM E18-15 standard. The results of the density test and hardness test showed a tendency for the value to increase with increasing compaction pressure applied. The highest density was 2.147 g/cm3 for a sample with a compaction of 4,600 Psi, with the highest hardness value being 53,11 HRB. Based on micro-photographs, it shows that the interlocking mechanical bonds at lower compaction pressures tend to be weak, fractures at the grain boundaries are clearly visible and the pattern of damage tends to show brittle/brittle fractures.

Abstract

This study aims to determine the optimal parameters in the CNC Milling process to produce low surface roughness and improve the quality of brake pad molds. By applying the Taguchi method, the results showed that the process parameters have a significant effect on surface roughness. Data analysis revealed that increasing feed speed and depth were positively correlated with surface roughness. Of the parameters tested, feed speed had the largest contribution of 40.46%, followed by feed depth of 14.01%, and spindle speed of 12.36%. The optimal parameter combination proposed to achieve the best surface roughness is a feed speed of 100 mm/min, a feed depth of 0.2 millimeters, and a spindle rotation of 3343 RPM. These findings provide an important contribution to the automotive industry to improve the efficiency and quality of brake pad production, a component that plays a crucial role in vehicle safety.

Abstract

Covid-19 tidak hanya berdampak pada kesehatan tapi juga pada perekomian khususnya ekonomi keluarga, merumahkan beberapa pekerja yang notabenya adalah kepala keluarga yang disebabkan oleh kebijakan pemerintah maupun kondisi perusahaan yang tidak baik menyebabkan turunnya penghasilan keluarga sehingga sulit untuk memenuhi kebutuhan sehari-hari. Dalam menyelesaikan permasalahan terseebut tidak hanya peran kepala keluarga yang dibutuhkan namun peran ibu rumah tangga juga sangat penting, ibu rumah tangga dapat membantu kepala keluarga mencari penghasilan tambahan, tugas ibu rumah tangga seperti memasak dapat menjadi salah satu sumber penghasilan tambahan keluarga. Ibu rumah tangga yang aktif mencari tambahan penghasilan namun tetap menjalankan perannya di rumah dikenal dengan istilah Mompreneur. Pembinaan mengenai pengembangan ekonomi keluarga berbasis mompreneur akan meningkatkan pengetahuan ibu rumah tangga mengenai aktivitas yang dapat dilakukan untuk menambah penghasilan keluarga dengan memanfaatkan tugas ibu rumah tangga yang biasa dilakukan.
