This paper considers and compares the hysteresis stress and strain and the penetration property of spur gear assemblies based on three unique designs. Spur gear plays an important part in mechanical structures, and any mechanical setup should consider the execution of such a mechanical component under distinct designs to improve its mechanical productivity and sustainability. To explore the ways in which the mechanical behaviour of the designs varies with the design configurations, we integrate simulation analysis with an experimental study. The outcomes of this paper indicate considerable differences in both hysteresis stress, strain distribution, and penetration behavior measurements between three designs. The paper explains the stated disparities by the unique geometric layouts and material characteristics of each design. Furthermore, it emphasizes that some of the examined designs have lower hysteresis losses and favourable stress and strain distributions, which positively affects the long-term performance of gear systems. Other designs, however, exhibit severe penetration and stress concentrations leading to rapid gear wear and likely premature failure. In distinguishing these events, the present study offers a valuable approach to the parameters that influence the performance of gear systems and aids in the improvement of the design methodology.

In the current paper, AA6101-T6 aluminium alloy was subjected to friction stir welding (FSW) utilizing a vertical milling machine. Alloy plates were welded in butt position to provide a virtually flat interface, using a tool shape that was carefully selected. Because of the excessive generation of heat via the tool and workpieces during friction stir welding, substantial deformation in the nugget zone is seen. The mechanical attributes of the base metal at the joint are significantly impacted by an excessive variation in temperature at the weld. In this experiment, mechanical properties-related changes through the FSW process are kept to a minimum to achieve high tensile strength. The tool’s rotating speed (measured in rpm), the workpieces' traverse speed (measured in mm/min), and the tool tilt angle were chosen as the parameters to regulate the weld quality. As a result of its 44% contribution, the rotating speed parameter is shown to be the most beneficial one for stir welding. The metric determining transverse speed contributes the least, at 19%. For effective stir welding, such as high strength welds, defect-free welds, short welding times, low welding costs, etc., it is preferred that the tool rotational speed parameter be concentrated. By using sustainable Taguchi approach to optimize the chosen process parameter, high tensile strength is achieved at the welded connection.

A2L classified refrigerants provide extended application range at highest safety level versus A3 classified refrigerants, but R-32 still carries a Global Warming Potential (GWP) of 675 making it a transitional solution. This paper compares different relevant parameters and points out the advantages provided by HFO A2L low GWP refrigerants (like R-454B and R-454C) for a wide capacity range of air to water and brine to water heat pumps. A special focus is put on the application of building restoration.

In the face of a global pandemic, the ever-present threat of climate change and the highly unstable economic and social global systems the resource poor smallholder farmer is increasingly finding it harder to meet with the daily challenges of sustaining the livelihood of the farmer and his family. This paper is a review of the challenges of smallholder’s rubber farmers, strategies adopted to build the resilience of the farmers and technological adaptations to sustain the resilience of the smallholder’s rubber farmers in Nigeria. The work looked at the manipulation of space or spacing techniques in rubber-based agroforestry systems, mixed farming in rubber production, cropping patterns, soil nutrient and weed management methods and socioeconomic benefits to the rubber smallholders. The results indicated that RBAF systems helped resource poor rural farmers increase family food supply, improved income and reduced the gestation period of rubber leading to improved livelihood. This results will help in attracting more smallholders to rubber plantation establishment, leading to increased national rubber production for local and international markets and increase industrial development in rubber and rubber related products.

The paper studies the problem of overall assessment of energy sector development options from the standpoint of meeting energy security requirements. It is shown that as the projection time frame extends further into the future, its economic component gains in importance on a par with integral indicators descriptive of strategic threats to and sustainability of energy systems development. Methodological approaches to assessment of these indicators are proposed.

Increasing the number of ship repair that make improvements it can be ensured that the greater the level of pollution will occur. Facilities (Infrastructure) is very helpful to minimize the pollution that will occur when ship repair. If the conditions of Infrastructure make it possible to flourish nowadays, which will further improve environmental performance. Development to improve domestic shipyard Infrastructure sustainability is very importance since 20% of national ship repair is still undertaken in foreign shipyard. This indicates that the ability of national shipyards still need to be improved especially in the infrastructure and facilities sector as production supports. This paper used data sample was undertaken in State-Owned Shipyard industry located in North Jakarta. Data analysis was undertaken starting from the ship entry, repair process until the accomplishment of ship repair. This research is testing the chemical impacts with related chemical parameters around the shipyard. the results showed that dangerous chemical concentrations were located around the shipyard and threatened the surrounding aquatic ecosystems. there needs to be management of shipbuilding infrastructure management that can minimize hazardous waste, especially basic storage. Basically the improvement of shipyard infrastructure can be undertaken if the ship repair process keeps increasing.

The aims of this paper to identify a relationship of social capital with the participation of women in their community to realize the sustainablity of rive in urban areas and to achieve resilience of the city. Efforts to increase women’s participation in urban planning and environmental management require the support of social capital in local contexts to achieve sustainability of river in urban areas. The method used in this research is a quantitative approach, with this type of research is descriptive-explanatory. Data collection techniques in this study by conducting surveys with questionnaire disseminating and literature study. The research location was undertaken in DKI Jakarta as the metropolitan city has the complexity of problems because of the density of citizens and environmental degradation, especially in the river area. The result of this study shows the social capital of the community has a relation to the proactive participation of women. The activity of capacity building for women for environmental management need to strengthen the values of togetherness and trust to actors who are the drivers of citizens and the implementers of community empowerment. The implication of this study can be used for strategy in protecting of the river in urban areas to adopting a more environmentally friendly approach by integrating gender equality.

Policy makers throughout the world have accepted climate change as a repercussion of fossil fuel exploitation. This has led the governments to integrate renewable energy streams in their national energy mix. PV off-grid Systems have been at the forefront of this transition because of their permanently increasing efficiency and cost effectiveness. These systems are expected to produce large amount of different waste streams at the end of their lifetime. It is important that these waste streams should be recycled because of the lack of available resources. Our study found that separate researches have been carried out to increase the efficiencies of recycling of individual PV system components but there is a lack of a comprehensive methodical research which details efficient and sustainable recycling processes for the entire PV off-grid system. This paper reviews the current and future recycling technologies for PV off-grid systems and presents a scheme of the most sustainable recycling technologies which have the potential for adoption. Full Recovery End-of-Life Photovoltaic (FRELP) recycling technology can offer opportunities to sustainably recycle crystalline silicon PV modules. Electro-hydrometallurgical process & Vacuum technologies can be used for recovering lead from lead acid batteries with a high recovery rate. The metals in the WEEE can be recycled by using a combination of biometallurgical technology, vacuum metallurgical technology and other advanced metallurgical technologies (utrasonical, mechano-chemical technology) while the plastic components can be effectively recycled without separation by using compatibilizers. All these advanced technologies when used in combination with each other provide sustainable recycling options for growing PV off-grid systems waste. These promising technologies still need further improvement and require proper integration techniques before implementation.
