This study introduces a novel methodology for addressing power-related challenges in Virtual Reality (VR) technology by exploring the potential utilization of Low-Temperature Solid Oxide Fuel Cells (LTSOFCs). Despite the capacity of VR headsets in providing immersive experiences, there is frequent limitations encountered due to power supply which a...

This paper examines the development and characterization of composite cathodes for low-temperature solid oxide fuel cells (SOFCs) utilizing gadolinium-doped ceria (GDC) as the electrolyte material. The advantages of operating SOFCs at low temperatures include increased durability, decreased material costs, and improved startup characteristics. The...

As the usage of alternative energy sources grows more widespread in developing nations, it will be crucial to monitor their development. Moreover, control of the utilization of these renewable energy sources is crucial. Rapid advances in virtual reality (VR) and augmented reality (AR) have paved the way for immersive visualization to expedite the s...

Hydropower is one of the renewable energy technology alternatives to produce and provide electricity to grid-off and country applications with almost zero carbon and other harmful gases emission. Almost 20% of the World's electricity generation is contributed by hydropower, which considers to be one of the highest power generation systems. Malaysia...

This study aims to determine how much the FSKTM buildings in UTHM utilized energy and also to identify factors affecting the usage. An end-use energy analysis was conducted on the building to identify energy apportioning and energy end-use based on different categories such as ACMV system, lighting system, IT equipment, and other electrical equipme...

Solid oxide fuel cell (SOFC) is a promising technology for energy conversion efficiency. Electrochemical processes convert the chemical energy of a variety of substances into direct current power. Typically, these reactions occur at temperatures between 400 and 1000 °C. In recent years, a substantial quantity of research has been conducted on inter...

Water Quality Monitoring is crucial in determining the healthy level of a river. The variety of methods for monitoring water quality is essential to cover mistakes or damage in the future. For this reason, the comparison between the multivariate approach and the existing water quality index formulation was carried out in this study. The secondary d...

Wind power harvesting in a low wind speed zone necessitates more energy analysis than development in a moderate to high wind speed region as choosing the right wind turbine generator in such a region is more critical. Therefore, in this study, a detailed assessment of wind energy potentials in the Batu Pahat district of Johor, Malaysia is conducted...

In addition to early childhood through high school (secondary education), teacher preparation, and higher education pertaining to teacher professional development and/or learning education are all topics covered in the journal. Teachers and students were required to work from home during the COVID-19 situation. As a result, the teaching and learnin...

Gua Sireh is located in Baling, Kedah, Malaysia. Baling is a district that hold a variety of unique and beautiful geological features with geoheritage values and attractive geological landforms. The Gua Sireh is currently conserved by the Kampung Padang Che Mas’s committee members as a part of their tourism site. The aim of this paper is to formall...

A high concentration of palm oil biodiesel fuel blend is a strong candidate to substitute conventional diesel fuel (B10) due to its prospect to release fewer emissions. This paper shall present findings when testing palm oil biodiesel fuel blends (B10, B20, and B30) at medium speed (2500 rpm) in a single-cylinder Yanmar L70N diesel engine coupled t...

Fluidised bed combustion (FBC) has been recognised as a suitable technology for converting a wide variety of fuels into energy. In a fluidised bed, the air is passed through a bed of granular solids resting on a distributor plate. Distributor plate plays an essential role as it determines the gas-solid movement and mixing pattern in a fluidised bed...

Battery Electric Vehicles (BEVs) is a promising technology. However, it suffers from low range characteristics thus increasing the anxiety to prospect customers and hindering its market penetration. To overcome this challenge, a range extender that can generate additional power to charge the battery could be the solution. This brief review article...

Black pepper (piper nigrum) is one of the well-known spices extensively used worldwide. Drying is the most popular methods of preserving the black pepper. Unfortunately, this operation may negatively influence product quality. Moreover, due to the high heat capacity of water, drying is usually a long-lasting and energy-intensive process, thus new d...
