Abstract

Blowout Preventers (BOPs) are critical safety devices in drilling operations and operate in abrasive, high‑pressure environments that accelerate wear and failure. This study applies two Non‑Destructive Testing (NDT) methods, Liquid Penetrant Testing (LPT) and Magnetic Particle Testing (MPT), to identify surface defects on RAM BOP components, and integrates finite‑element‑based crack propagation simulation to assess the risk of further damage. LPT was applied to coated/non‑ferromagnetic parts, while MPT was used for ferromagnetic components, referencing ASME Section V acceptance criteria. Inspections revealed defects including a 4.9 mm crack on the piston shaft and pitting corrosion (≈0.8-5.3 mm) on several parts (e.g., cavity upper, housing). The simulation, with 3000 psi operating pressure and an initial flaw (l = 3 mm; h = 1 mm; r = 0.6 mm), predicted stress concentration at the crack tip (up to ~141 MPa) and potential growth toward ~7.9-11.7 mm if unrepaired. Recommended actions include re‑welding cracked regions and polishing minor scratches/pitting, combined with periodic NDT for early detection. The integrated NDT-simulation workflow supports proactive maintenance, enhances operational safety, and mitigates failure risk.

Abstract

Corn has a high post-harvest moisture content (20-40%), making drying very important to maintain quality and extend shelf life. This study investigated the effect of drum rotation speed in a rotary dryer on the drying characteristics of corn and compared it with solar drying. The drying method was carried out using an LPG-fueled rotary dryer with an inlet air temperature of 70°C and an air flow velocity of 7.9 m/s. The drum rotation speed was varied at 6 rpm, 9 rpm, and 12 rpm with an initial corn mass of 5 kg. Drying was carried out for 6 hours. And data collection was carried out every 30 minutes during the drying process. As a result, a higher drum rotation speed significantly increased the drying rate. A speed of 12 rpm showed the best performance with a maximum drying rate of 0.46 kg/hour and an average of 0.24 kg/hour. However, the highest energy efficiency was obtained at a speed of 6 rpm, indicating that lower speeds require less energy despite longer drying times. Overall, the rotary dryer performed better than solar drying in reducing corn moisture content more quickly, stably, and controlled in a shorter time

Abstract

The rapid increase in global energy demand, driven by industrial growth and the challenges of climate change, makes energy efficiency a top priority in the manufacturing sector. Industrial cooling and production processes consume large amounts of electricity and water, contributing to high operational costs and environmental impacts. This research aims to evaluate and improve energy efficiency in a manufacturing production process through the integration of the Sustainable Overall Throughput Effectiveness (SOTE) and Eco-Management and Audit Scheme (EMAS) methods. The research was conducted using a case study approach at XYZ Company, a multinational manufacturer of heat exchangers operating in Indonesia. Electricity and water consumption data for 2024 were analyzed, focusing on a selected production process with high energy intensity. The EMAS framework was used to identify sources of energy and water inefficiency through environmental audits, while SOTE was applied to evaluate production performance by considering availability, performance, quality, and sustainability index parameters. The research results indicate that the integration of SOTE and EMAS can provide a comprehensive and structured approach to identifying energy waste without sacrificing the quality of production output. This study proves that improving energy efficiency can be systematically integrated into operational performance management, thereby supporting the achievement of sustainability targets while increasing productivity. This integrated approach provides a practical reference for manufacturing companies in aligning operational excellence with environmental sustainability.

Abstract

This study examines the corrosion resistance performance and failure mechanisms of a hybrid coating system based on castor oil and nano-SiO₂ with three particle size variations (20 nm, 100 nm, and 500 nm) applied to ASTM A36 steel. We compared uncoated samples with three coating variants to evaluate the effect of nano-SiO₂ size on corrosion resistance and damage development. Coating resistance was tested using potentiodynamic polarization, FTIR analysis, corrosion morphology characterization, and coating thickness measurements. Compared to uncoated steel, the formulation with 100 nm nano-SiO₂ provided the greatest improvement, with a three-order decrease in corrosion current density (icorr = 1.33×10⁻⁸ A/cm²) and a shift in corrosion potential toward a more positive direction, accompanied by stable surface morphology and minimal chemical changes. This effectiveness is achieved through homogeneous particle dispersion, which produces a dense barrier structure and tortuous diffusion pathways without a significant increase in thickness. Failure mechanism analysis shows that small particle sizes (20 nm) trigger porous barrier breakdown due to nano-silica aggregation, while large particles (500 nm) cause coating cracking and localized pitting due to sedimentation and excessive thickness. In contrast, the 100 nm size stabilizes the passive film and suppresses pit initiation. These findings confirm that controlling the size and dispersion of nano-SiO₂ not only improves corrosion resistance but also determines the dominant failure pathway in coatings. This research contributes to the development of sustainable bio-nano coatings for structural applications by highlighting the importance of microstructural reinforcement and understanding failure mechanisms in designing high-resistance coating systems.

Abstract

This study investigates the effect of electroplating duration on the hardness and coating thickness of nickel layers deposited on aluminum substrates. Nickel electroplating was performed with immersion times of 17, 34, 51, and 68 min to evaluate the correlation between deposition time, microstructural development, and mechanical enhancement. Microstructural analysis revealed a progressive increase in coating thickness from 3 μm, 7 μm, 11 μm, to a maximum of 44 μm as plating duration increased. Correspondingly, surface hardness exhibited a substantial rise, with untreated aluminum showing 69.44 HV, while electroplated specimens achieved 118.32 HV, 191.32 HV, 258.40 HV, and 418.62 HV, respectively. This increase of up to 502% demonstrates that longer electroplating durations produce denser and finer nickel microstructures, contributing significantly to surface strengthening. The findings confirm that nickel electroplating is an effective method for enhancing the mechanical performance and surface quality of aluminum, with deposition time serving as a critical parameter in optimizing coating characteristics.

Abstract

Go-kart aerodynamics involves a trade-off between drag reduction, lift control, and longitudinal stability, yet most previous studies do not explicitly constrain pitching moment during design optimization. This study proposes a CFD-validated Gaussian Process Regression (Kriging) surrogate for multi objective aerodynamic optimization of go-kart bodywork using ground clearance, nose angle, and operating speed as design variables. A 25-point maximin Latin hypercube design was evaluated using steady RANS CFD, and the surrogate was used to construct a drag-lift Pareto front under an uncertainty-aware pitching moment constraint at 65 km/h. The recommended knee point design (h = 40 mm, α = 24.79°) achieved Cd = 0.771, Cl = 0.157, and Cm.pitch = 0.171. Compared with the baseline, it reduced lift and pitching moment by about 35% each, with a 4.6% drag penalty. Additional CFD checks at 42 and 89 km/h confirmed that the selected design remained feasible and stable across the operating range. These results demonstrate that surrogate-assisted, stability-constrained optimization can identify practically viable go-kart configurations that improve aerodynamic stability without a large drag penalty, providing a useful framework for bodywork tuning within the studied design range.

Abstract

Enhancing thermal efficiency in double-pipe heat exchangers has become a key industrial priority to reduce energy consumption, with passive methods such as pipe geometry modification receiving significant attention. This study investigates the comprehensive thermal and hydraulic performance of concave corrugated tubes (CCT) with triangular, square, and trapezoidal profiles. A three-dimensional numerical simulation was employed, utilizing the finite volume method and the SST k-ω turbulence model over a Reynolds number range of 7700 to 13,800. The results indicate that all CCT geometries improve thermal performance compared to plain tubes, with the square profile showing the highest increase in Nusselt number (13.87–16.59%). This enhancement is attributed to higher turbulence intensity, which, however, also results in the greatest hydraulic penalty due to dominant form drag. Performance Evaluation Criteria (PEC) analysis yielded values above 1 for all geometries, with the square profile being optimal at lower Reynolds numbers, whereas the triangular profile outperformed the others at higher flow rates (Re 12,300), with a PEC value of 1.023. In conclusion, corrugated geometries have been shown to enhance thermal performance, but the associated hydraulic penalties necessitate careful selection based on the operational flow range to achieve an optimal balance between heat-transfer gains and pumping-power requirements.

Abstract

This study aims to evaluate the combined effects of low level ethanol blending and CVT roller mass variation on the power and torque characteristics of a 110 cc automatic motorcycle. Experiments were conducted using two Pertalite–ethanol fuel blends, E5 and E15, in combination with CVT roller masses ranging from 10 g to 14 g. Engine performance was evaluated using a dynotest, enabling direct measurement of the power–rpm and torque–rpm characteristics for each fuel–roller configuration. The results indicate that increasing the ethanol content from 5% to 15% leads to a consistent improvement in engine performance across the tested range. Compared with E5, the E15 blend produces higher peak power and torque while maintaining the performance peak within the mid range engine speed region that is favorable for CVT operation. Among the tested configurations, the combination of E15 fuel with an 11 g roller delivers the best overall performance, achieving a maximum power of 8.94 hp at approximately 7,200 rpm and a peak torque of 9.21 Nm at around 7,000 rpm. In contrast, heavier rollers tend to reduce peak torque and shift the effective power band toward higher engine speeds, which is less beneficial for daily riding conditions. These findings demonstrate the interaction between fuel blending and CVT roller mass in shaping the power–torque characteristics of automatic motorcycles and provide practical guidance for optimizing performance under everyday operating conditions.

Abstract

This study investigates the structural performance of three stopper mounting designs for conveyor systems using finite element simulations in ANSYS Workbench. The analysis was conducted using a static structural method, where a vertical downward load of 103.43 N converted from the total weight of the stopper was applied to the structure, and fixed support boundary conditions were assigned at the mounting base. We compared the original design with two modified versions, including one reinforced with stiffening ribs. We evaluated each model under static loads by measuring total deformation, equivalent stress, elastic strain, and safety factor. Compared to the original design, MD 1 reduced total deformation by 88.42%, elastic strain by 53.04%, and equivalent stress by 30.72%, while increasing the safety factor by 0.94%. These improvements were achieved without significantly increasing material usage. The addition of stiffening ribs effectively directed internal forces, stabilized stress zones, and enhanced structural resilience. The original design, while functional, exhibited high deformation and uneven stress distribution that limited its suitability for precision-dependent operations. Reinforcing the geometry proved essential in achieving better mechanical performance and durability. This validates the use of local structural enhancement as a key strategy in mechanical design. The findings contribute to automation system development by highlighting the importance of local reinforcement in precision-oriented automation components.

Abstract

Solar energy is considered one of the most promising renewable energy sources because it has the most reliable application potential in energy conservation. The main objective in this study is to compare the performance of two hemispherical solar still models, namely the Hemispherical Solar Still Black Paint (HSSBP) and the Hemispherical Solar Still Internal Reflective Mirror (HSSIRM). Enhancing solar distiller productivity and cost efficiency is profoundly influenced by its material design. Previous literature did not utilize more efficient materials in the solar distiller. The method of the current article utilizes relatively efficient materials for the cover of the solar distiller, which is made of acrylic with a thickness of 2 mm. The cylindrical seawater basin is made of iron with a diameter of 40 cm. This comprehensive study aims to increase the clean water production of the solar distiller by using an experimental setup use water levels different starting from 1cm, 2cm, and 3cm. The experimental results revealed that the seawater basin with a depth of 3 cm in section III achieved the highest cumulative productivity. Freshwater produced from model HSSBP in section III is 955 mL/m², compared to the productivity of 1 cm and 2 cm, which yielded 557 mL/m² and 875 mL/m². Then model HSSIRM can only produce 557 mL/m². The conclusion is productivity of the HSSBP model is better than that of the HSSIRM model.
