The poor insulation of concrete masonry units prompted researchers to investigate the effects of adding fiber rice straw and recycled rubber granules from waste tires to replace aggregates in concrete masonry production. The use of rice straw and rubber from waste tires has helped to create more sustainable building units by using recycled materials and reducing the energy consumption of buildings. An experimental investigation was conducted to explore the mechanical and thermal properties effects of the addition of different proportions of rice straw and shredded rubber as aggregate substitut

Clean water crisis is a significant concern in the Frontier, Outermost, and Disadvantaged regions in Indonesia, particularly on small islands. To overcome the concern, the development of desalination technology based on solar energy is essential due to the limited sources of electrical energy in these islands. In addition, solar thermal desalination (STD) technology provides sustainable prospects for providing clean, low-cost water. Among the available STD technology, the use of Solar Still (SS) has proven to be effective due to its potential to produce clean water from seawater at lower costs

The increase in cattle rustling throughout many nations is worrying for the socio-economic and political stability of the region. Cattle rustling has been linked to fatalities, a rise in the number of those accused, and security issues. It has aided in the spread of poverty in countries like Kenya thus causing community instability. In most African nations, pastoral farmers’ way of life revolves around their livestock. Due to the export of beef to the European Union, the beef industry is Botswana’s second-largest contributor to GDP. If cattle rustling episodes are allowed to continue, ther

All internal combustion engines have a high rate of energy loss while operating; the cooling and exhaust systems of the engine squander the vast majority of the energy generated during combustion. The use of this energy improves engine efficiency. One application of this power is to improve the efficiency of the engine's air pumping, which is done via a turbocharger. Use thermoelectric generators (TEGs) to convert heat energy into electrical energy. A thermoelectric generator type (12715) mounted outside the exhaust terminal was used in this study. A system consisting of four thermoelectric ge

The decline in oil production is currently a big challenge. To overcome this problem, the Enhanced Oil Recovery (EOR) method was used. The EOR method used is surfactants, such as AOS Surfactant (alpha-olefin sulfonate). This laboratory research used five AOS concentrations (0.3; 0.5; 0.75; 0.9; 1%), with a salinity of 7,000 ppm. AOS was chosen because of its ability to reduce interfacial tension. The research carried out was a phase behavior test to assess the stability of the emulsion for 14 days at a temperature of 80C. The process of making a surfactant solution involves mixing AOS powde
