1.6 million barrels of fuel oil were exported in one day when it was at its peak, the huge consumption of non-renewable fuel sources is happening now, and it is increasing over time. Indonesian citizens still rely on oil fuels, such as LPG and crude oil. Even though it is not only Indonesia that consumes a lot of oil, but also America, Japan, and many more. The equation is that they are using non-renewable sources, although they can take thousands of years for that. Now we have to look for other sources of energy that can be renewed faster than that. Not only renewable but also not a negative impact on the environment, cheap and most importantly easy to make. Looking better at biomass, it is generally a product of dry organic matter, or basically just dry plant or organic matter. Biomass is divided into many things such as biogas, biodiesel, bio briquettes, and biokerosene. But this team has their own reasons why they choose to make briquettes over the others. This team could choose bioethanol because it is very effective, instead of buying vehicle fuel we can just make it. But regardless of the effectiveness, to use bioethanol in a vehicle, the vehicle must be modified first which makes it very complicated. Coupled with using this method, we cannot ignore the consequences of vehicles producing deadly and toxic pollution. Therefore, we chose bio briquettes. First, another name for green energy, which is an environmentally friendly energy source. Given that this briquette is made from natural ingredients and does not cause smoke, it is very safe for the environment. Second, it is non-toxic, the manufacturing process is carried out using a natural process, and is made with additional ingredients of tapioca flour from cassava as an adhesive for briquette dough. Therefore, this briquette uses harmless materials with many advantages. Our team has a brilliant idea, while others may only use one main ingredient such as pine cones, rice husks or corn cobs, here the researcher will combine the three ingredients to get optimal results. Darmatasah (2012) tried to make briquettes from rice husks only and it did not contaminate fresh O2 (data). As for Mapai and friends, the making of briquettes from rice husks and corn cobs has been carried out with the highest heat (composition of 75% corn cobs, and 25% rice husks) of 22343.78 kj / kg or 5336,720 kj / kg, which qualified for briquette standard quality. Moreover, by using corn cobs the durability of briquettes is quite long compared to other materials. These ingredients have their own unique way of being beneficial. With these easily available materials, both of them can save money and also make items discarded useful for their daily needs. The research method used was experimental and carbonization methods using corncob, pine strobilus, and rice husks as alternative energy sources in the form of briquettes. The form of charcoal briquettes used is a cylindrical shape with a charcoal particle size of 100 mesh. The independent variable in this study is the holding time, the mold model, the drying temperature, the drying time and the composition of the material, while the dependent variable is the time the briquettes run out. The raw materials for making briquettes used in this study were corn cob, pine strobilus, and rice husks obtained from agricultural waste, weighed in a ratio of 4: 3: 3 and 3: 4: 3. Meanwhile, tapioca flour is used as an adhesive for briquettes. The equipment used in this research includes carbonization tools, sieves, mortars, ovens, scales, water kettle, aluminum pans, and printing tools. The results show that briquettes made from agricultural waste can be used as an alternative fuel that can replace coal briquettes which are classified as Nonrenewable. This research also proves that this briquette is classified as an environmentally friendly product and also easy to make by everyone without using factory tools. With this, it can be concluded that briquettes made from biomass have many advantages, one of which is that they are environmentally friendly products because they emit less smoke than other briquettes, are easy to make and can also be used as an alternative fuel to replace coal.
CHARS-CSR (Charcoal briquettes, a mixture of corncob, strobilus and rice husks) Environmentally friendly
Coal is a non-renewable fuel and is very difficult to renew, while coal has a very important role in this world. Over time, coal fuel will be depleted and depleted, therefore this CHARS was created to become an alternative fuel to replace coal by utilizing agricultural waste to meet the needs of cheap and environmentally friendly alternative household fuels in order to create an energy independent society. The material used in this research is a mixture of pine strobilus, rice husks and corncob which is converted firstinto charcoal, then the charcoal is mashed, mixed and molded in various forms of briquettes such as cylinders, cubes, and eggs. In this research, the methods to be used are experimental and carbonization by utilizing a mixture of agricultural waste. From some of the results of this research, in general CHARS was not too different from coal briquettes from all aspects. Therefore, CHARS can be used as fuel for the natural rubber drying process. The results showed that the dith material is easily available, can save money and could also make the materials discarded useful for everyday needs.
