Abstract

3D printing technology is one of the latest innovations in the manufacturing industry. One of the uses of 3D printing is manufacturing products and machine components such as making coupling components on the Z axis of a 3D printer machine. 3D printing technology works by extruding thermoplastic filaments to form layers of material gradually. In this research, the filament used is PLA (Polylactic Acid) filament with a diameter of 1.75 mm. This research aims to analyze the effect of process parameters on surface roughness using response surface methodology (RSM). The parameters tested were nozzle temperature (215°C, 230°C, 245°C), layer height (0.2 mm, 0.25 mm, 0.30 mm), and print speed (50 mm/s, 65 mm/s, 80 mm/s). The results showed that nozzle temperature and layer height significantly influenced the surface roughness results. The most optimal process parameters to minimize surface roughness are at nozzle temperature of 249°C, layer height of 0,17 mm, and print speed of 90 mm/s.

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

This Community Service Program aims to address production challenges faced by the Berkah Utama Snack business group, which operates in the fishery processing industry, specifically the production of fish crackers and kemplang (fish crackers). The business group, led by Mrs. Rika Trisdasawati, is located in the Sinar Jaya neighborhood of Sinar Jaya Jelutung Village, Sungailiat District, Bangka. The main challenges faced by partners were limited and worn-out production equipment, including worn and unhygienic fish grinding machines, manual kneading processes, and low-capacity packaging equipment. This resulted in a production capacity of only 10 kg per day, insufficient to meet consumer demand. The implementation method for this activity involved six main stages: (1) identifying partner needs through field observations, (2) designing machines according to technical specifications using CAD software, (3) manufacturing machines at the Polman Negeri Babel Mechanical Workshop with the involvement of technicians and students, (4) operational testing with partners, (5) operational mentoring, and (6) technology dissemination to partners. The results of this activity demonstrated significant achievements in the form of the construction and delivery of three production machines. First, a fish grinding machine with a 40x40 mm L-shaped angle iron frame, a 5.5 HP internal combustion engine, and a pulley-belt transmission system. Second, a stainless steel dough mixer with a 550x450x550 mm dough tube, a Ø30x370 mm screw mixer shaft, and a gear system for heavy loads. Third, a packaging machine equipped with a 1500x800x700 mm table stand. This program has succeeded in increasing partners' production capacity, improving the hygiene of the production process, and reducing dependence on manual labor. In addition, this activity also provides appropriate technology transfer to local communities and strengthens the regional economy by increasing the productivity of fishery product processing business groups.

Abstract

Penelitian ini bertujuan untuk menyelidiki pengaruh variasi persentase matriks resin fenolik dan tekanan kompaksi terhadap sifat mekanik dan fisik komposit hibrid berbasis resin fenolik yang diperkuat serbuk logam (aluminium, kuningan, silika) serta abu sekam padi (RHA) menggunakan metode metalurgi serbuk. Persentase matriks yang digunakan adalah 46%, 54%, dan 62%, sedangkan tekanan kompaksi divariasikan pada 5000 Psi, 5300 Psi, dan 5600 Psi, dengan setiap kombinasi diulang sebanyak tiga kali. Uji kekerasan dilakukan menggunakan metode Brinell, dan densitas diukur dengan prinsip Archimedes. Data hasil pengujian dianalisis menggunakan ANOVA faktorial dua faktor untuk mengetahui signifikansi masing-masing variabel. Hasil penelitian menunjukkan bahwa tekanan kompaksi tidak berpengaruh signifikan terhadap kekerasan maupun densitas, sedangkan persentase matriks berpengaruh signifikan terhadap kedua sifat tersebut. Kombinasi optimal diperoleh pada matriks 46 % dan kompaksi 5000 Psi dengan nilai kekerasan 82 HRB. Densitas tertinggi dicapai pada tekanan 5000 psi dan matriks 46%, dengan nilai 1,461 g/cm³. Temuan ini menunjukkan bahwa komposit yang dihasilkan berpotensi kuat sebagai material alternatif ramah lingkungan dan aman untuk kampas rem non-asbes.

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

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
