Abstract

Abstract Fuel oil (BBM) consumption in Indonesia has increased from year to year, but the availability of fuel oil will gradually become scarce. Bioethanol can be used as a substitute for fuel oil (BBM) depending on its purity level. Bioethanol is a liquid resulting from the fermentation process of sugar from carbohydrates which has good prospects as a liquid fuel with raw materials that are renewable, environmentally friendly and very profitable economically. Bioethanol can be used as a gasoline mixture for vehicle fuel and can be used as cooking fuel in households. The use of bioethanol can reduce CO gas emissions significantly. Bioethanol can be used directly as fuel oil or mixed into premium as an additive in a certain ratio (Gasohol or Gasoline alcohol). If mixed into gasoline, bioethanol can increase the octane number significantly. Bioethanol is known as an environmentally friendly fuel, because it is free from pollutant emissions. Bioethanol can be made from plant raw materials that contain starch such as cassava, sweet potato, corn, sago and molasses. One of the materials that can be used to make fuel from ethanol is the cassava plant. Cassava is a tuber that contains carbohydrates that come from the roots of the cassava plant. Cassava is very easy to plant and maintenance is not difficult. Cassava is usually used as a substitute for rice, but can also be used as an alternative to fuel oil. This research is qualitative research with a descriptive approach. Researchers use research data in the form of secondary data obtained from a number of credible sources such as scientific articles, books and a number of other sources that are credible and commonly used in research. These data were analyzed using analytical tools with stages of data collection, data selection, data reduction and drawing conclusions. Keywords: Fuel Oil, Bioethanol, Cassava

Abstract

Abstract Agriculture is an important sector for Indonesia. Because around 30% of the population works in the agricultural industry. Currently, agricultural conditions in Indonesia are facing challenges due to climate anomalies. Unpredictable climate changes, shorter growing seasons, an increase in pests and diseases and these conditions have an impact on increasing production costs while yields are not optimal. Climate change is one of the obstacles in increasing plant productivity. The negative impacts of extreme global climate change include the degradation of land and water resources, damage to agricultural and irrigation infrastructure, the emergence of floods and droughts, and increased attacks by pests and plant diseases. Therefore, farmers need knowledge and farming skills that are adaptive to climate change or what is known as Climate Smart Agriculture (CSA). Climate Smart Agriculture is a useful approach to guide the actions needed to transform and reorient agricultural systems to effectively support development and ensure food security in conditions of climate change. CSA technology focuses on climate resilience and food security with the main objectives being: 1.) Increasing agricultural productivity and income in a sustainable manner, 2.) Adapting and building food security to climate change, 3.) Reducing and minimizing greenhouse gas emissions (Mitigation), 4.) Optimizing the use of various resources. So it is hoped that optimal results will be obtained in the agricultural sector. This research is qualitative research with a descriptive approach. The researchers use research data in the form of secondary data obtained from a number of credible sources such as scientific articles, books and a number of other sources that are credible and commonly used in research. These data were analyzed using analytical tools with stages of data collection, data selection, data reduction and drawing conclusions.
