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

Pemasangan cetakan (mold) pada mesin injeksi plastik membutuhkan alat bantu karena bobot mold relatif besar dan area kerja mesin sering terbatas. Pada kondisi tertentu, penggunaan alat bantu umum belum mampu menjangkau posisi pemasangan dengan baik sehingga proses kerja menjadi kurang efisien dan berisiko bagi operator. Penelitian ini bertujuan merancang alat angkat cetakan dari arah samping untuk mesin Woojin TE170G5 dengan kapasitas angkat 2 ton. Metode perancangan yang digunakan adalah VDI 2222 melalui tahapan identifikasi kebutuhan, pengembangan konsep, pemilihan alternatif, dan penyelesaian rancangan. Data penelitian diperoleh melalui observasi kondisi mesin, pengukuran area kerja, serta studi literatur. Model alat dibuat dan dianalisis menggunakan SolidWorks Simulation untuk mengevaluasi tegangan Von Mises, displacement, serta faktor keamanan. Hasil simulasi menunjukkan tegangan maksimum rangka sebesar 0,629 MPa dan displacement maksimum sebesar 0,004 mm. Analisis pin connector menunjukkan gaya maksimum sebesar 12.004 N pada Pin 1 dengan tegangan geser 26,55 MPa. Nilai tersebut masih berada di bawah tegangan luluh material ASTM A36, sehingga rancangan dinyatakan aman terhadap beban kerja. Meskipun demikian, nilai Factor of Safety yang tinggi perlu menjadi perhatian karena dapat mengindikasikan peluang optimasi dimensi dan biaya produksi.

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.

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

Complex problems in machine assembly processes are often caused by inefficient product designs, such as excessive component count and long assembly time. This study aims to analyze the application of the Design for Assembly (DFA) method to the design of a plastic shredder machine body to improve assembly efficiency and manufacturing ease. The research method includes component analysis, assembly feasibility evaluation using DFA parameters, and assembly efficiency index calculation based on the Boothroyd and Dewhurst approach. The analysis results show that the redesigned body using DFA reduced the number of components by 25% and decreased estimated assembly time by 32% compared to the initial design. Moreover, the assembly efficiency increased from 45% to 66%, indicating a simpler, more ergonomic, and cost-effective design. Thus, the DFA method proved effective in optimizing the design of the plastic shredder machine body, making it easier to assemble and manufacture without reducing its structural strength.

Abstract

Efficient product design not only focuses on functionality and structural strength but also emphasizes the ease of the assembly process. This study aims to analyze the application of the Design for Assembly (DFA) method in the body design process of a product to achieve a more efficient and easily assembled structure. The DFA method is used to evaluate the number of components, assembly sequence, assembly time, and the level of difficulty in installing each component. The analysis compares several body design alternatives based on criteria such as manufacturability, ease of maintenance, and assembly efficiency. The results show that the application of DFA principles can reduce unnecessary components, minimize assembly time, and improve structural efficiency by more than 20%. Therefore, implementing the Design for Assembly concept at the design stage can produce a simpler, more economical, and easily assembled product body without compromising its strength or functionality.
