Abstract

Using Aluminum 7075 at a high temperature of 50 degrees Celsius, this study examines the effect of various blank geometry angles on the mechanical properties of strain and stress during the deep drawing process. This study systematically examines the impact of different blank geometry angles on the deformation behavior, strain distribution, and stress concentration during the deep drawing process of Aluminum 7075 sheet using a numerical simulation approach. To describe the behavior of the material against the effect of the angle on the pressure in the simulation taking into account realistic parameters, the main point is the result of the pressure treatment of the predetermined angle on the results of the strains and stresses created. The obtained results, which include strain distribution, stress concentration, and overall mechanical reaction, provide important information for the choice of the best blank geometry angle in deep drawing of Aluminum 7075 at high temperatures. This research contributes to the advancement of process optimization in the metal forming industry, providing a solid foundation for improving efficiency and quality in deep drawing operations involving high-strength aluminum alloys.

Abstract

Nickel oxide (NiO) is a material used due to its remarkable chemical stability, magnetic properties, and electrical characteristics molecules. One notable feature of NiO is its unreactive surface with water (H2O), making it an ideal candidate for use as a cathode in the electrolysis process to produce hydrogen (H2) gas. During electrolyte process, H2 is produced through the oxidation reaction at the anode and the reduction reaction at the cathode. Despite its potential, the detailed mechanism of H2O molecule decomposition using a NiO electrode remains inadequately explained. This research aims to elucidate the increased energy arising from the attractive forces between NiO and H2O molecules. To investigate these attractive forces, simulations were conducted to understand the chemical characteristics of the molecules, including bond lengths, bond angles, and their properties. The results indicated that the use of NiO electrode could increase the potential and kinetic energy of H2O molecules. This energy increase is attributed to the formation of specific polar and non-polar bonds. Specifically, polar bonds were formed between (1) the nickel (Ni) atom in NiO molecules and the oxygen (O) atom in the H2O molecules and (2) the O atom in NiO molecules and the H atom in the H2O molecules. Non-polar bonds were formed between (1) the H atom in the H2O molecules and the Ni atom in NiO molecules, and (2) the O atom in NiO molecules and the O atom in H2O molecules. This study highlights how these interactions help in the electrolysis process by enabling the efficient breakdown of water molecules and the production of hydrogen gas

Abstract

The frequent occurrence of landslides in the Ngantang District, Malang Regency, especially in Ngantru Village, is caused by topographic conditions, where the area is hilly because it is located at the foot of Mount Kelud. Likewise, along the Banu Irrigation Area Channel there are points prone to landslides, especially in the upstream part. These landslides result in the channel breaking so that the irrigation water supply is disrupted. DPT (Soil Retaining Wall) is a building structure whose role is to maintain the stability of the soil on sloping land. The existence of this wall is expected to be able to prevent the soil from moving or landslides. Therefore, to protect the Banu Irrigation Area Channel, a DPT construction was built where the DPT details used were stone masonry construction or the Gravity Wall type. With a total height of 3.9 m, the bottom sole width is 1.00 m and the upper sole width is 0.50 m. The purpose of this paper is to analyze whether the existing DPT is safe  against the forces that work, especially analyzing its stability, then comparing it with other DPT designs with the Cantilever Wall type. Based on the analysis of calculations for the Existing Gravity Type Earth Retaining Wall, the stability figures for soil bearing capacity σ max= 23.76 > 15.012 (safe ), stability against sliding hazards Fgs=3.321 ≥ 1.5 (safe ), and stability against sliding hazards Fgs=3.321 ≥ 1.5 (safe ) are obtained. = 6.26 > 1.5 (safe ) while for cost calculations the value obtained is IDR 180,390,000.00 (One Hundred and Eighty Million Three Hundred and Ninety Thousand Rupiah). Meanwhile, for the analysis of the comparative soil retaining wall for the cantilever type, the stability figures for soil bearing capacity σ max= 25.92 > 15.012 (safe), stability against sliding hazards Fgs=3.55 ≥ 1.5 (safe ), and stability against overturning hazards were obtained. SF= 6.64 > 1.5 (safe ).

Abstract

Reconstruction following climate change induced disasters is often required after possible destruction of the built heritage. Achieving greater disaster resilience and reducing disaster risk due to climate change requires that such reconstruction must be balanced with financial and technical feasibility while conserving the historic character of the heritage building. The ‘Build-Back-Better’ mantra is mostly embraced during disaster induced reconstruction, and seeks to build safer and more resilient structures, to reduce pre-disaster vulnerabilities. The ‘Build-Back-Better’ approach assumes that there were vulnerabilities within the pre-disaster built environments that need to be rectified during reconstruction to enhance resilience. As such, achieving building conservation and climate adaptation during reconstruction might at first glance appear completely divergent. Conservation mostly focuses on maintaining the fabric of a place in its existing state, while adaptation may require updating/altering the components of an existing building. However, a more thorough understanding may lead to the conclusion that there is a convergence. This is because the conservation of the built heritage should contribute to resilience, in many ways similar to adaptation, especially in the context of post-disaster recovery. A divergence will result in a fairly unprecedented exposure to natural hazards triggered by climate change, and amplify the performance deficiencies, in terms of functional, technological and normative obsolescence. A convergence is needed due to the increasing requirements of safety, well-being and accessibility of the historic and architectural values, whose conservation is sought. Flooding is the most widely spread climate change induced disaster that affects the built environment globally. This study highlights how heritage conservation can techno-economically align with the resilience agenda, during reconstruction following flood disasters induced by climate change.

Abstract

Air pollution poses a significant threat to human health and environmental sustainability, exacerbated by anthropogenic activities such as industrial emissions, vehicle exhaust, and fossil fuel combustion. Major pollutants include carbon monoxide (CO), nitrogen dioxide (NO2), hydrocarbons (HC), sulfur dioxide (SO2), ozone (O3), particulate matter (PM2.5), particulate matter (PM10), and etc. In this study, an Early Warning System (EWS) was developed integrating sensors, microcontroller, IEEE 802.11 network, web interface monitoring, and Instant Messaging. The system uses the CART algorithm to analyze the data, with sensors that detect CO, NO2, and HC. The evaluation of the system demonstrated its effectiveness, with recorded pollutant concentrations of 1.401 ppm for CO, 0.639 ppm for NO2, and 0.860 ppm for HC, and identified correlations between these pollutants. The EWS proved capable of providing timely alerts, ensuring continuous monitoring and management of indoor air quality, and contributing to public health and environmental protection.

Abstract

This paper presents the design and simulation of an infrared emitter driver circuit for the MILES (Multiple Integrated Laser Engagement System) application. The circuit aims to efficiently drive a high-power IR emitter, maximizing output power while maintaining compatibility with low-power embedded systems (e.g., ESP32). Key design considerations include the selection of an appropriate IR diode emitter, driver circuit topology (utilizing a push-pull amplifier and low-side MOSFET driver for fast switching), pulse shaping techniques to optimize rise and fall times, and thermal management strategies. Simulation results demonstrate the effectiveness of the proposed design in achieving high power output (4.5W) with fast switching speeds and minimal ringing, suitable for MILES applications requiring precise and rapid IR LED control.
