Methane is a significant contributor to global warming, ranking second only to carbon dioxide in its impact. According to the International Energy Agency (IEA), methane accounts for roughly 30% of the current global temperature increase. One of the primary sources of methane emissions is the improper management of crop waste. Therefore, our objective is to produce R-Yan using crop waste specifically from papaya stalks and banana stems and crafting it into scientific models. The materials required for producing R-Yan are papaya stalks, banana stems, sodium hydroxide, and water. By soaking the papaya stalks and banana stems in a sodium hydroxide solution, non-cellulosic substances can be effectively removed. After the removal of these substances, the cellulosic fibres are dried under the sun for five hours. The dried fibres are then spun into yarn, which can be used to craft scientific models. Load testing has demonstrated that R-Yan can withstand loads ranging from 800 grams to 1 kilogram. In conclusion, recycling crop waste like papaya stalks and banana stems into R-Yan not only helps reduce methane emissions from landfills but also provides an eco-friendlier material for yarn production. This approach aims to set an example that encourages further recycling efforts and contributes to environmental sustainability.
