Abstract

Technology is currently experiencing rapid development, especially in the field of industrial engineering materials. One of the advances in industrial engineering materials is the use of ornamental plants as materials for making composites. Natural fiber reinforced composites are the right choice to be used as composite materials. The aim of the research is to obtain the highest tensile test values at fiber lengths of 60 mm, 80 mm, 100 mm and fiber volume fractions of 10%, 20%, 30% with 6% NaOH alkaline treatment for 1 hour and heating at 80? for 2 hours. The method used is full factorial. Samples were made using the hand lay-up method. The influence of fiber length and fiber volume fraction on tensile testing is very large. The longer the fiber used, the greater the tensile strength. Likewise with the percentage of fiber, the more it is, the stronger it is. The highest tensile strength was 39.03 Mpa at a fiber length of 100 mm and a volume fraction of 30%. Meanwhile, the lowest tensile strength result was 15.07 MPa at a fiber length of 60 mm and a fiber volume fraction of 10%. From the test results, the tongue-in-law composite can be used to make helmets, because its tensile strength value is higher than the tensile strength of SNI helmet material which is only 33.93 MPa.

Abstract

Fried onions made from shallots are an important type of horticultural crop and are very often used by the public. The process of making fried onions is carried out in several stages until it becomes fried onions that are ready to be consumed, starting from peeling the onion skin, slicing, frying, draining and packing. From the results of a survey conducted on partners, the process of slicing onions is still done manually using a slicing tool made of wood. Mrs. Yuliana, who currently produces fried onions, reaches 10 kg/day for Monday - Thursday, and Friday - Sunday 15-20 kg/day, and for religious holidays usually the capacity produced can reach 60 kg/day, with a total on average 500 kg per month, you have to replace the slicer every 4 months. The tool currently used to slice onions has a capacity of 10 kg/hour, so it requires more energy and time for the slicing process. In order to increase the production of shallots and produce slices as is done today, a shallot slicing machine was developed with a slicing system similar to the tool used. Partners receive appropriate technology in the form of shallot slicing machines and training on the process of using the machine and maintaining the machine. Apart from that, a monitoring and evaluation process is also carried out to measure the level of success and obstacles to the machines used by partners. After developing a red onion slicing machine, partner production productivity increased, the machine can function well and is capable of peeling 2.5 kg of red onion skin in 4 minutes in one process or 37.5 kg/hour.

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

Minimal Surface Roughness results are the desired goal in the CNC Milling machining process for circular motion side cutting with the right machining process parameters in order to obtain minimal workpiece Surface Roughness response results. This study was conducted in order to obtain parameters that contribute greatly to surface roughness and determine the effect of parameter variations on the LAGUN MC 750 CNC milling machine using the Taguchi research method. The machining process parameters varied were spindle speed (2,400 RPM, 3000 RPM), depth of feed (0.2 mm, 0.4 mm) and feeding movement (clockwise, counterclockwise) using S45C steel material. The results of this study show that minimal roughness results are obtained with a spindle speed of 2400 RPM, a depth of feed of 0.2 mm, and a counterclockwise feeding movement.

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.
