Abstract

This study aims to design a conceptual model of a grass chopper machine to assist in the preparation of livestock feed. The design process was carried out systematically through several stages, including need identification, functional analysis using the Black Box method, development of alternatives via a morphological chart, and evaluation of concepts using a weighted Likert scale. The analysis produced three conceptual design variants (AVK1, AVK2, and AVK3), which were evaluated based on six criteria: functional achievement, manufacturing time, safety, durability, ease of assembly, and maintenance. Based on the evaluation results, AVK3 was selected as the best concept with the highest total score of 4.45. The outcome of this conceptual design is expected to serve as a reference for the future development of an efficient and ergonomic grass chopper machine suitable for small to medium-scale farmers.

Abstract

The benchmark for the results of the machining process can be seen from the results of the products, one of which is the level of surface smoothness. The purpose of this experimental research is to find out how much cutting speed (Vc) and depth of cutting produce a workpiece with the smoothest level of surface roughness for the turning process carried out by students at the Bangka Belitung State Manufacturing Polytechnic Workshop. This research is using experimental method. The cutting speeds (Vc) used were 23 m/min, 24 m/min, 25 m/min, the cutting depths used were 0.5 mm, 0.8 mm, and 1.0 mm and the feeding speed was set at 0.040 mm/rev. The results showed that the best turning results using a cutting speed (Vc) of 23 m/min was using a cutting depth of 0.5 mm with a roughness value (Ra) of 1.372 m, using a cutting speed (Vc) of 24 m/min using a depth of cut. 0.5 mm with a roughness value (Ra) of 1.189 m and using a cutting speed (Vc) of 25 m/min using a depth of 0.5 mm with a surface roughness value (Ra) of 3.14 m. The lowest value for the level of surface roughness of the turning process was obtained using a cutting speed (Vc) of 24 m/min with a depth of 0.5 mm with a surface roughness value (Ra) of 1.189 m.

Abstract

3D printing technology is an additive manufacturing technology (layer by layer) to create 3D objects with melted filament material. With this 3D printer, users can create a ready-to-use product. This research uses ABS (Acrylonitrile Butadiene Styrene) filament because mechanically this filament is very strong and has resistance to high temperatures. This study aims to find the highest tensile test value from 3D printer printing results with ABS filament specimens, for the factors used are infill layer thickness, wall printing speed, nozzle temperature, bed temperature, print speed, fan speed, infill density, wall thickness, top layers, bottom layers, infill overlap, retraction distance, and retraction speed. Printing is done with the Anycubic 4Max 3D printing machine, while the specimen size is 115 mm x 19 mm x 4 mm. This study uses the Taguchi L16 method with 13 factors and 2 levels printed as many as 48 specimens. So that the tensile test results were obtained with the highest value of 30.46 MPa in the second experiment the lowest with a value of 25.31 MPa in the third experiment. For the calculation of the S/N ratio, the most influential factor is the fan speed.

Abstract

This study aims to compare the performance of four types of blades, namely cutter knives, razor blades, wood carving knives, and meat blender knives, on a 220 ml portable plastic packaging shredder. The research was conducted through experimental testing to determine the durability and cutting efficiency of each type of blade under workload during the shredding process. The test results showed that the wood carving knife had the best performance with a cutting force of 1 N, producing the highest number of cuts, totaling 41 plastic cups compared to the other knives. The cutter knife ranked second with 38 cuts, while the razor blade and meat blender knife showed the lowest results. The combination of an optimal wedge angle and low cutting force makes the wood carving knife the most efficient choice for a portable plastic shredder. The results of this study are expected to serve as a reference in selecting effective and economical blades to support small and medium scale plastic waste recycling process.
