Abstract

Mathematics is a subject whose field of study is abstract and requires the ability to think logically so that to convey it, a medium is needed so that students become more understanding of the material presented and stimulate students to improve their ability to think logically. One of the learning media that is in accordance with current developments is the use of software. Using the GeoGebra Software provides several advantages, including geometric drawings which are usually produced more quickly and accurately than using a pencil, ruler or compass. The existence of animation facilities and manipulation movements (dragging) in the GeoGebra Software can provide a clearer visual experience for students in understanding geometric concepts. Can be used as an evaluation to ensure that the painting that has been made is correct. Make it easier for teachers and students to investigate or show the properties that apply to a geogebraic object. The method used in this activity is an interactive lecture that is chosen to deliver software geoebra which is carried out in three stages, namely the field assessment stage, the implementation stage, and the evaluation stage. By using this GeoGebra software, it can increase the knowledge and understanding of teachers in learning mathematics and can produce teaching materials based on GeoGebra.

Abstract

This mentoring and training activity aims to reduce organic waste produced by households and convert it into environmentally friendly products. Implementation can be done through making eco enzymes that can be applied in households. Eco enzyme is a product made from the fermentation reaction of organic waste with brown sugar. Eco enzymes can be made by mixing organic waste, brown sugar/molasses, and water with a mass ratio of 3:1:10. This service activity consists of preliminary, implementation and evaluation stages. In the preliminary stage the team prepared the eco enzyme material. Then, at the implementation stage, assistance activities were carried out in making eco enzymes. Next, at the evaluation stage, a questionnaire is filled out regarding the implementation of service. From the results of the questionnaire it was found that 85.71% were very interested in eco enzymes, as many as 91.43% of residents would make eco enzymes at home by utilizing organic waste from households, as many as 74.29% of residents wanted to develop a business from eco enzyme products, As many as 91.43% of residents wanted to use eco enzyme products in household activities and as many as 85.71% of residents expressed satisfaction with the socialization and assistance activities for making eco enzymes that had been carried out. Through this activity, it is hoped that residents will be more creative and innovative in processing organic waste.
