Coloring materials for fabric painting can be produced from natural dyes and synthetic dyes. Natural and synthetic dyes have their respective advantages and disadvantages. The combination of the two colors will give the impression of a brighter color, and slightly reduce environmental pollution. The objectives of this research are: 1) Knowing the processing of synthetic and natural dyes for fabric painting; 2) Knowing the results of applying synthetic and natural dyes to fabric painting. The method used in this research is the research and development approach model Research and Development (R&D) and data analysis. Trials in this study were carried out with dye using 4 types of cloth with the help of a validator as an assessor of the coloring results. The results of this study indicate that synthetic dyes are lighter than natural dyes. Meanwhile, the colors produced from natural dyes tend to be darker. In painting this cloth, the writer needs a combination of dark and light colors. Therefore, the use of synthetic and natural dyes requires mixing of colors. The fading test conducted by the author for the color absorption of diamond crape on the fabric is very good. Thus it can be concluded that the use of natural and synthetic dyes can be applied to fabric painting by conducting trials first to get the right color.

Where the Bantargebang location is a final waste collection site which is the main disposal site for around 6,500 tons of waste per day from all over Jakarta. Plastic bag waste is a serious enemy for environmental sustainability. The difficulty in breaking down makes plastic waste need proper handling so that it does not accumulate. One way is to do an ecobrick. Ecobrik is a plastic waste management method that is very easy for everyone to do and has a very high impact on environmental conservation. We do community service by disseminating the benefits of ecobricks, as well as providing training on how to do ecobricks together with Cikiwul residents. Training using the zoom platform, adapting to current conditions, activities are carried out by discussing and providing training videos on how to make ecobricks. It is hoped that this activity can reduce plastic waste, which its usefulness can be maximized into new objects that have useful values.AbstrakCikiwul merupakan salah satu kelurahan yang berada pada kecamatan Bantargebang.

Virtual teachers are devices or agents with the function of replacing the role of humans (teachers) with their teaching skills. The virtual teacher also has a function as task facilitator and is presented during training, especially when the teacher is actually not present. The virtual teacher's objectivity is carried out by explaining the subject matter in a virtual environment, for example, virtual independent learning. In the western world, virtual schools are quite widely applied, especially to students who are homeschooling. In a virtual school, all materials, assignments and grades are accessed via the internet. The virtual teacher concept refers to a device that provides guidance and practice. Teachers who are equipped with interactive agent functions that can provide direction and feedback in order to improve student abilities. By utilizing natural language processing (NLP) and pattern matching to help students learn alone without being accompanied by a teacher. NLP is used as a learning tool as outlined in the text of the sentence as part of the learning material which is done virtually. Meanwhile, pattern matching is used to group the questions asked so that the computer can gain an understanding of the questions posed by students. This grouping aims to solve problems with different word order which basically have different meanings. The teacher has the facility to make material, make questions, and answer student questions. A teacher can add knowledge about the database to enrich the source of knowledge for students.

Recent technological developments determine humans to be creative in creating tools that implement technology in it with the aim of facilitating human tasks in daily activities. Inappropriate use of fertilizers can cause losses, both losses on fertilizer, on plants, as well as on the soil and the environment around fertilization. Losses on plants such as unhealthy plant growth and susceptible to disease pests, plant yields are not as expected or low. From the background above, the writer found an idea to create a system or tool that can help farmers in determining the dose of Nitrogen fertilizer in their rice plants, through the storage of the dosage data of each land. The user did five scans, from each scan producing RGB values, each RGB value from five samples was then matched with the BWD dose color indicator. The sample dose results are then sent by the NodeMcu microcontroller to the webserver database. Based on the assessment of the test conducted by 10 Users by Gapoktan Farmers Group of Tosari Kendal Village, the total value of 372 that has been averaged to be 37.2 is between 31 - 40 which is classified in the category of "Very Valid or Very Effective".

The economic growth of Pekalongan Regency, which is getting better, is not followed by awareness of citizens in complying with tax payments in a timely manner and in accordance with their income. This can be seen from the level of taxpayer compliance in reporting annual tax return (SPT) taxes at KPP Pratama Pekalongan which is still lacking. Seeing the vision and mission of Pekalongan Regency, it gives encouragement to the community to continue to increase the potential of existing resources, for example in the fields of agriculture, trade, plantations, even in the field of education. Increased utilization of potential resources will lead to increased economic growth in Pekalongan Regency. Increasing economic growth is related to the awareness and compliance of Pekalongan Regency residents with taxes. This Community Service Activity (PKM) is expected to provide an introduction and encouragement for teachers to introduce and apply the importance of implementing tax compliance, both to fellow teachers, to students, and to the surrounding environment.
