Abstract

Higher education has a noble task, namely disseminating science and technology and cultural arts to all citizens with personal and institutional references to the principles of scientific methodology. Community capabilities need to be developed from various social strata by conveying the Tri Dharma of Higher Education, which is the main task of lecturers, this is a form of effort from universities to accelerate competitiveness to encourage the realization of government programs in national development. This community service activity is in collaboration with partners, namely high school and vocational schools (SMA / K) in Samarinda. The target of this program is to introduce and disseminate laboratory-based processing of plantation commodities at the Samarinda State Agricultural Polytechnic (PPNS) campus. From the results of observations in the field, there are still many high school / vocational students in Samarinda who are still not familiar with the processing technology of plantation commodities and the processing process and analysis techniques. The method of this activity is the delivery of material directly (lectures), discussion and deepening of the material by means of questions and answers, as well as simulation of laboratory-scale plantation commodity processing technology. The result of the implementation of this service is an increase in students' knowledge regarding plantation commodity processing technology and the students involved in this activity are able to master plantation commodity processing technology.

Abstract

Nutgrass is a common weed often found in agricultural fields. Its high population in agricultural land can have negative implications for farmers as it may prevent farmed crops from growing and producing as well. However, nutgrass has the potential to be developed into a biopesticide due to its phytochemical compounds. The purpose of this study is to identify secondary metabolite compounds present in nutgrass extract. On nutgrass extracts, the study used phytochemical screening techniques with ethanol (polar) and n-hexane (non-polar) solvents. According to the findings, ethanol and n-hexane solvents produced nutgrass extract yields of 10.81% and 0.65%, respectively. Alkaloids, flavonoids, saponins, tannins, and steroids were all present in nutgrass extracts made with ethanol, whereas only steroid components were present in extracts made with n-hexane. Saponins, tannins, alkaloids, flavonoids, and steroids are only a few of the secondary metabolite substances found in nutgrass extracts.
