Abstract

This research aims to determine the effect of stem cutting size on the growth of Gembili. The design used in this research was a Randomized Group Design (RAK) with 4 treatments repeated 3 times. The research treatments were M1 = cutting length 20 cm, M2 = cutting length 30 cm, M3 = cutting length 40 cm, and M4 = cutting length 50 cm. Data analysis uses variance, if the treatment has a significant effect, then the analysis continues using the Least Significant Difference test (LSD) with a confidence level of 95%. The results showed that the size of the cuttings had no significant effect on the growth of Gembili in all growth variables. The length of cuttings of 50 cm tended to show the highest increase in average values for all observed growth variables.

Abstract

This study presents a comprehensive bibliometric analysis aimed at mapping the progress and direction of sustainable agriculture research in Indonesia. With a focus on addressing environmental, social, and economic challenges while ensuring food security and agricultural productivity, sustainable agriculture has emerged as a critical area of focus globally. In Indonesia, a country rich in agricultural diversity and natural resources, sustainable agricultural practices are paramount to mitigate the impact of climate change, preserve biodiversity, and enhance the livelihoods of farmers and rural communities. Through systematic collection and analysis of relevant publications from academic databases, including Web of Science, Scopus, and Google Scholar, this study identifies key thematic areas, trends, collaboration networks among researchers, and potential research gaps within sustainable agriculture research in Indonesia. The analysis spans from 1982 to 2023, covering a wide range of topics such as agroecology, organic farming, precision agriculture, and sustainable resource management. Results reveal a significant impact of Indonesian research contributions, highlighting collaborative efforts and interdisciplinary approaches towards addressing complex agricultural sustainability challenges. The study provides valuable insights for policymakers, researchers, and stakeholders to prioritize areas for further development, formulate evidence-based policies, and foster interdisciplinary partnerships in promoting sustainable agricultural practices in Indonesia.

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
