Abstract

The development of manufacturing technology has developed so rapidly. In this study, SCM 440 steel material was used, which is an alloy steel of chromium molybdenum. This steel has the advantages of stable composition,low harmful elements,high steel purity. Surface roughness is important, surface roughness is defined as the irregularity of surface configuration in an object resulting from a finishing process. This study aims to determine the influence of process variables on the surface roughness rate of SCM 440 material by varying the total cutting angles of 700,750 and 800 then variations in feeding speed of 0.08mm, 0.09mm, and 0.10mm and spindle speed or RPM, namely 160,220, and 280 puts / min in the RSM method. The Rspon Surface method is a set of mathematical and statistical techniques that are useful for analyzing problems where several independent variables affect the response variable and determine the optimal value of the process variable. From the results of the study, the value of the Second order yˆ = + 0.092224 X1² + 0.208515 X2² - 0.03661 X3² was obtained. With stationary point value X0 = ( total Cut angle ) = - 0.382409, X0 = (feeding) = 0.161715, X0 = (RPM) = 0.578250. and found the optimal values of Wedge Angle (78.212), Feeding Speed (0.095 mm) and RPM (278.29 put/min). Then it can be analyzed the optimal value that is different from the value of the RSM method framework and if the values are the same then the research fails.

Abstract

In the world of manufacturing technology there is the latest breakthrough called 3D Printing which is based on layer manufacturing. In making products, a method of adding material in layers is used, usually called additive manufacturing. The principle used in this manufacturing process technology is layered modeling, by converting 3D data directly from computer-aided design (CAD) into a physical model. Many manufacturing technologies have been developed to make prototypes according to needs, for example FDM (Fused Deposition Modeling). Setting factors and experimental levels is an important step in maximizing the quality of research level products referring to transparent materials formed from polypropylene filaments. The factors that vary are Nozzle Temperature, Bed Temperature, Print Speed, and Layer Height. This research design uses the Taguchi method. This research uses an L9 orthogonal matrix with 3 levels. Based on the results of the research carried out, we can conclude that in the impact strength test there is an increase in the results of the impact strength test with the most influential process parameters, respectively, namely Print Speed (35mm/s), Layer Height (0.3mm), Bed Temperature (97 °C) and Nozzle Temperature (215°C) using Polypropylene filament. So the strongest impact strength test value is in experiment no. 2 with an average value of 0.03370 Joules and the weakest is in experiment no. 1 with an average value of 0.02959 Joules.

Abstract

Along with customer demand, the manufacturing industry must improve the quality of its products. In addition to product quality, environmental, safety, and health and welfare considerations also have a significant impact on the manufacturing business. One of the products of the manufacturing industry is a shaft which in its manufacture refers to the level of surface roughness. To minimize the surface roughness of the workpiece as a result of CNC lathe machining, coolant can be used. One of them is using coolant from vegetable oil. Vegetable oil is known as an ecologically acceptable and safe cooling medium for use in manufacturing operations. So a study was conducted to determine the surface roughness value of the workpiece (AISI 1045 steel) using 2 types of vegetable oil as a cooling medium (coconut oil and palm oil). Taguchi experimental design was used in this study. Based on the measurement results, the surface roughness value of AISI 1045 steel with palm oil coolant is 1.614 m, and coconut oil is 1.554 m. The coconut oil coolant type can optimize the minimum AISI 1045 steel surface roughness value with a value of 1,554 m at a cutting speed of 1273 rpm, a depth of cut of 0.50 mm, and a cutting motion of 0.16 mm/put.

Abstract

The manufacturing industry now demands machining processes that are not only precise but also highly efficient. Computer Numerical Control (CNC) machines such as CNC milling have emerged as the answer to these challenges by enabling high-precision mass production. The State Polytechnic of Manufacturing in Bangka Belitung has an aging CNC Milling Machine Lagun MC-750, which has been in use since the establishment of the campus several years ago. The research is focused on metrological testing of circular motion on the CNC Milling machine in the Mechanical Workshop of Polmanbabel. The analytical method involves experimental studies encompassing machining processes, data collection of the results, and data analysis. The machining process is carried out using the CNC Milling Machine Lagun MC-750 with specific parameters such as cutting depth, cutting speed, and feed motion. The test specimens are made of S45C steel with dimensions Ø31.6 x 50 mm. The analysis of 12 specimens revealed a value of 146 μm for clockwise feed motion (G02) and 174 μm for counterclockwise feed motion (G03) for the other 12 specimens. These results fall within the tolerance grade IT 10. This indicates that the machine is suitable for processing workpieces within standard tolerances, as IT 10 is commonly used in general machining for interchangeable parts that can also be classified as highly precise work.

Abstract

The Bangka Belitung Islands consist of two main islands, namely Bangka Island and Belitung Island, which have abundant marine natural resource potential. One of the typical products of the seafood is Kericu, which is a snack made from squid eggs and sago. Kericu has become a special souvenir that is in demand and has become a home-based business opportunity. UMKM "Ampiang Yu Erin" is one of the producers of keriku whose manufacture is still using manual methods, which causes obstacles in terms of worker fatigue and product inconsistencies. To overcome this problem, modifications to the crevice forming machine are carried out to improve production efficiency and product uniformity. Although the desired results have not yet been fully achieved, the trial showed progress close to the expected crease shape, confirming the importance of the mold in influencing the final quality of the product.

Abstract

The use of natural fiber-based composite materials is a key focus in reducing dependence on synthetic materials in the automotive industry. This study examines the impact of fiber volume fraction and orientation variations in Pandanus Tectorius fibers on the tensile strength of composites as an alternative material for car dashboards. These fibers were chosen for their good mechanical properties, eco-friendliness, and renewability.  The composites were made using a polyester resin matrix with fiber volume fractions of 3%, 5%, and 7%, and fiber orientations of random, vertical, and horizontal. Samples were prepared using the hand lay-up method following ASTM D 638 standards. Results revealed that both fiber volume fraction and orientation significantly influenced tensile strength. The combination of vertical fiber orientation and a 7% volume fraction yielded the highest tensile strength at 38,95 MPa, while horizontal fibers with a 3% volume fraction showed the lowest at 15,35 MPa. Tensile strength increased with more fibers aligned in the tensile force direction.  For comparison, ABS High Impact plastic used in dashboards has tensile strength ranging from 20 to 40 MPa. Thus, Pandanus Tectorius fiber composites meet strength requirements and present a promising eco-friendly alternative for automotive applications.

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 development of 3D printing technology has opened up great opportunities in various industries, especially in the manufacture of complex three-dimensional objects. However, the quality of the print results is greatly influenced by the physical and mechanical properties of the filament used. The filament production process, especially in filament extruder machines, requires extra attention to operational parameters such as extrusion temperature and screw rotation speed. Variations in these parameters significantly affect filament quality, such as tensile strength and thickness, which can decrease if not properly adjusted. This study aims to analyze the effect of extrusion temperature and screw rotation speed parameters on filament quality, and to determine the optimal settings using the Taguchi method. The results showed that screw rotation speed is the most significant faktor in determining filament diameter with a contribution of 73%. In addition, extrusion temperature contributes 17.6%. Through optimization using the Taguchi method, it is known that the optimal extrusion temperature is 250°C with a screw rotation speed of 5 RPM, producing filament with a diameter of 1.8 mm.
