Abstract

Advances in additive manufacturing (AM) technology have opened up opportunities for the rapid and precise production of complex components, including those used in unmanned aerial vehicle (UAV) structures. However, ABS material prints often exhibit variations in quality due to the influence of various interacting process parameters. This study aims to analyze the influence of four parameters: infill pattern, layer thickness, print speed, and chamber temperature on two important mechanical properties: ultimate tensile strength (UTS) and elongation. The Taguchi method with an experimental design using an orthogonal array L9(3⁴) was applied to minimize the number of trials without sacrificing important information. The tensile test data were analyzed using the signal-to-noise ratio (S/N ratio) and Analysis of Variance (ANOVA). The results showed that the infill pattern was the most dominant parameter, contributing 80.78% to UTS and 73.16% to elongation. Chamber temperature has a significant effect on elongation (19.78%), as it enhances interlayer bonding through temperature control in the printing chamber. Layer thickness contributes moderately to UTS (10.01%), while print speed has the smallest effect on both responses. These findings emphasize the importance of selecting the appropriate combination of parameters to consistently improve ABS print quality and serve as a foundation for developing process standards based on experimental data.

Abstract

The field of materials and technology has developed rapidly, various types of inventions have been developed and researched to obtain new materials that are suitable for use at low production costs. The potential of bamboo plants is promising where the availability is abundant and sustainable, the utilization of specimens is made with polyester binders reinforced with natural and synthetic fibers. The type of bamboo that will be investigated for the tensile strength and toughness of the specimen with the difference in fiber volume fraction is a reference for the combination of bamboo fiber and fiber-glass where the volume fraction of 25% SB:25% FG, 35% SB:15% FG and 40% SB:10% FG particles at a fixed resin volume is 50%. Of the three variations in the volume fraction, the highest tensile strength in a balanced fiber filler is 40% bamboo fiber: 10% fiber-glass with an average value of 80.907 MPa, with a tensile strain of 2.53 % The lowest tensile strength value is in the volume fraction of 35% bamboo fiber: 15% fiber-glass with an average value of 75.552 MPa, with a tensile strain of 2.09%. For the highest toughness value of the specimen is in the volume fraction of 35% bamboo fiber: 15% fiber-glass, i.e., 0.83 J〖/mm〗^2 With an absorbed energy of 43.73 joules. On the other hand, the lowest toughness value is in the volume fraction of 25% bamboo fiber: 25% fiber-glass with an average value of 0.24 J〖/mm〗^2. With an absorbed energy of 39.94 joules. The observation results showed that the fiber volume was good at a percentage of 40% SB with 15% FG suitable for combination as an alternative tensile material. The toughness value in the volume fraction of 40% SB:10% FG is very low. However, the observation of bamboo fiber fracture results has a strong enough ability for the application of manufacturing products and others.

Abstract

A common issue encountered with main heat exchanger equipment is improper operation, which can lead to the development of cracks in the stainless-steel pipes. The welding process alters the metal microstructure in the heat-affected zone, thereby affecting the mechanical properties of the welded joint. To mitigate this issue, TIG welding with argon shielding gas is employed. This method helps prevent oxidation and ensures the formation of a stable welding arc in 304 stainless steel, which is renowned for its excellent mechanical properties and corrosion resistance. The objective of this study is to evaluate the impact of variations in shielding gas flow on the mechanical properties of 304 stainless steel plates during the TIG welding process. The aim is to determine the optimal settings for producing robust and long-lasting welded joints. To assess the hardness of the welded joints, we employed a Brinell-type Hardness Tester FB-3000LC machine. A Brinell steel ball indenter measuring 5 mm on the HBW scale and applying a load of 125 Kgf was utilized. At a protective gas flow rate of 8 L/min, the average tensile stress was 44.72 N/mm², strain was 0.177, modulus of elasticity was 2518 MPa, and hardness was 99.712 HBW. Increasing the gas flow rate to 13 L/min resulted in an average tensile stress of 47.50 N/mm², strain of 0.189, elastic modulus of 2525 MPa, and hardness of 105.522 HBW. Further increasing the gas flow rate to 18 L/min led to an average tensile stress of 49.69 N/mm², strain of 0.192, modulus of elasticity of 2597 MPa, and hardness of 106.704 HBW. Based on the research findings, it was observed that the weld area exhibited an increase in hardness values due to the heat generated during the welding process. The use of protective gas flow during welding is deemed effective in producing well-formed welded joints, as it prevents fractures from occurring within the weld area during the tensile test process. The choice of protective gas is determined by the dimensions of the material plate.

Abstract

Salah satu penyebab fraktur pada tulang ialah kecelakan pada saat beraktifitas maupun berkendara. Penggunaan pelat implan metatarsophalangeal (MTP) menjadi satu dari berbagai macam metode penanganan fraktur pada tulang. Maka penting untuk mengetahui kemampuan pelat implan dalam menahan segala jenis pembebanan yang mungkin terjadi saat digunakan di tubuh manusia. metode yang digunakan untuk menganalisis kekuatan struktur pelat implan MTP ini adalah dengan menggunakan finite element method. Terdapat tiga tahapan dalam metode ini. Tahapan pertama adalah preprocessing, jenis material dan jenis meshing ditentukan pada tahapan ini. Lalu tahap solution, yaitu penentuan jenis pembebanan dan constraint  yang digunakan. Terakhir tahapan post processing, yaitu proses analisis hasil simulasi yang dilakukan pada dua tahapan sebelumnya. Pada penelitian ini didapatkan nilai von-mises stress dengan pembebanan 44.228 N hingga 200 N sebesar 51.492 MPa hingga 232.85 MPa. Nilai tersebut masih berada di bawah nilai tegangan luluh material Ti-6Al-4V yakni sebesar 880 MPa. Nilai von-mises stress yang rendah tersebut mengakibatkan deformasi total dan deformasi sumbu Z yang terjadi cukup rendah, rata-rata pada angka 0.0189 mm dan 8,77x10-4 mm. Berdasarkan perolehan nilai tersebut dapat disimpulkan pelat implan MTP dengan material Ti-6Al-4V tidak terjadi deformasi plastis. Deformasi yang terjadi pada  pelat implan MTP adalah deformasi elastis, dengan nilai yang cukup rendah. Sehingga aman digunakan sebagai salah satu alat bantu dalam proses penyembuhan fraktur pada tulang MTP.

Abstract

Industri pupuk menghasilkan limbah cair yang mengandung kadar amonium (NH4+) yang tinggi sehingga akan sangat berbahaya bila limbah ini dibuang secara langsung ke perairan karena akan langsung merusak ekosistem perairan. Untuk mengurangi dampak negatif tersebut, perlu adanya recoveriy atau pengurangan kadar amonium dalam limbah. Struvite (MgNH4PO4.6H2O) memiliki karakteristik yang slow release, artinya pupuk dapat melepas secara lambat senyawa yang diperlukan tanaman. Limbah garam (bittern) adalah pereaksi yang merupakan sumber Mg2+ pada produksi struvite. Untuk menurunkan biaya produksi sedapat mungkin digunakan limbah sebagai pereaksi untuk menghasilkan produk tersebut. Tujuan penelitian ini ialah untuk menurunkan konsentrasi limbah cair industri pupuk urea dengan pembuatan struvite. Pembentukan kristal struvite  dengan variabel tetap yaitu pH 9 dan variabel bebas yaitu perbandingan reaktan Mg:PO4. Hasil penelitian dari perbandingan molar Mg:NH4+:PO4 1:1:1 penurunan NH4+ maksimum adalah 132.5 mg/L. Penurunan konsentrasi  NH4+ meningkat pada molar reaktan Mg2+ yang lebih besar yaitu pada rasio molar Mg:PO4 1,2:1 mencapai penurunan konsentrasi optimum 75 mg/L. Produk struvite yang dihasilkan juga diperoleh pada molar reaktan pada Mg:PO4 1,2:1 yaitu 11.4 gr. Produk pupuk struvite dianalisa menggunakan XRD.

Abstract

Efforts to manage waste are being carried out at various levels, ranging from households to large-scale industries that generate waste on a daily basis. The imbalance between waste generation and proper management has turned waste into a serious environmental concern. Among the different types of waste, plastic is one of the most difficult to naturally decompose (non-biodegradable) and represents the largest portion compared to other waste materials. Statistical data show that in several cities across Indonesia, the amount of non-biodegradable waste disposed of at final disposal sites reaches 6,598.23 tons per day. This study was conducted with both general and specific objectives. The general aim was to utilize plastic waste as a composite material, while the specific objective was to analyze the tensile strength properties of composites produced from plastic waste reinforced with durian fibers. By exploring the potential of plastic waste in construction materials, this research seeks to provide a sustainable solution to the plastic waste problem while contributing to environmental preservation. Four different specimens were prepared for testing: Specimen A (80% plastic waste and 20% durian fiber), Specimen B (60% plastic waste and 40% durian fiber), Specimen C (40% plastic waste and 60% durian fiber), and Specimen D (20% plastic waste and 80% durian fiber). The results revealed that Specimen B exhibited the highest average tensile strength of 20.9 MPa, indicating significant potential for enhancing material performance. In contrast, Specimen D showed the lowest average tensile strength of only 1.2 MPa, highlighting the need for further composition optimization to improve mechanical properties. Overall, this study provides valuable insights into the development of recycled composite materials for use in construction and broader industrial applications.

Abstract

Laser marking has become an industrial trend to label a product to avoid problems arising from errors in product placement, labels can also be other markers depending on needs, laser marking can provide good writing prints on steel sheets. However, problems arise due to poor parameter input errors resulting in marking reading results that cannot be read by the scanner machine, this study aims to provide an analysis of the influence of laser marking input variations that can provide good marking quality, to determine the quality of marking, researchers use a Logitech camera assisted by Open CV programming, to see the quality of laser marking results that can be read by the scanner. This research method begins with inputting 6 parameter variations including speed, laser power and laser frequency, then Open CV programming is carried out to obtain image reading quality with color and line recognition, the reading results will automatically display the error level of the study. The results of the study explain the first test with a high error rate due to low input variables so that the reading is not clear, while the error value is 104040 in color recognition and 69024 in lines that are read with a 100% end range. The lowest error value is in the second test with the highest input variable, namely 1309 in black and white color recognition and 1345 in lines with a range of 100%, therefore the sixth test can be read clearly and well.

Abstract

Control systems education often faces a dichotomy between costly physical laboratories and accessible but numerically inaccurate simulation platforms, such as web-based simulators. Existing web-solutions typically rely on low-order integration methods, failing to capture realistic non-linear behaviors crucial for industrial applications. This study addresses these limitations by developing a high-fidelity, client-side Virtual Laboratory for DC Motor control. The novelty of this work lies in the integration of the Runge-Kutta 4th Order (RK4) algorithm within a lightweight HTML5/JavaScript architecture, eliminating server-side latency while ensuring superior numerical precision over standard Euler-based applets. Furthermore, the system implements a realistic discrete PID controller with a Conditional Integration (Clamping) Anti-Windup strategy, enabling precise analysis of actuator saturation effects. Validation benchmarks against standard numerical computing software like GNU Octave demonstrate rigorous accuracy. The proposed system achieves a steady-state relative error of less than 0.001% and shows negligible deviation in transient response metrics (rise time, settling time, and overshoot). Additionally, the virtual lab maintains identical closed-loop pole locations up to four decimal places. By integrating real-time Bode Plot and Root Locus analysis, this platform provides a robust, open-access tool that effectively bridges the gap between theoretical design and practical non-linear implementation challenges.
