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".

Kaliwungu Dream Building Shop is a business engaged in the sale of building materials and building-producing tools. This trading business sells various materials and tools for building buildings such as sand, cement, nails, paint, hammers and so on. The Dream Building Shop was founded by Mr. Zaenal, whose address is Jalan Raya Sekopek No. 10 Sarirejo Kaliwungu, Kendal Regency. Kaliwungu Dream Building Shop in recording sales transactions, purchases and reports - reports still use the manual method by writing them into a book, this method still requires time which is relatively old and prone to calculation errors, as a result you have to work 2 times or even many times to recalculate transactions that occur. Factors that are generally controlled are human errors that occur in cooking data and storing & maintaining paper-shaped documents, where this is very difficult to overcome. In addition, the process of searching for data or inventory is also less effective and efficient. also affect customers, even though performance according to the store is needed to satisfy customers.

In village development, the availability of accurate village profile data has an impact on its consistency policy direction.  However, there are some problems that are encountered to be able to update it including the quality of human resources, finance and infrastructure. Therefore, Community Service Program (PKM) activity is intended to provide knowledge about the importance of updating data in planning village development and helping the government update profile data and potential of their villages. The method used is training in updating basic data based on family data which is carried out by providing material and its implementation in the field. Community Service Program can be carried out according to the planned schedule, especially in the provision of training materials. Meanwhile, implementation of material in the training could not be carried out because it was constrained because lack of information technology. However, in general the Community Service Program in Neglasari Village was going well, marked by an increasing participant knowledge and an acceleration of online data updating assisted by students who were doing Community Service Program. Indirectly, this achievement at the same time show that the obstacles faced by Neglasari Village were not only on its human resources but rather on aspects of financial support and infrastructure. The actual presence from the government is needed to support the updating of the profile and potential data of this village because it is not only the village institution that requires it, but rather the central and regional governments.

In the daily use of technology, humans cannot be separated from the internet as a need to exchange information. People at this time spend more time in front of computer screens, laptops, even smartphones to find out information, send data to some of their friends. One of the information that is often sought or sent is a file. Apart from that, image files are files that are much searched for and sent, and many also contain important information in them. Image file security is of course very important so that unauthorized parties do not hack or manipulate information from the image. There is a way to secure information so that it does not leak to unauthorized parties, namely by using cryptography and steganography. By combining these two methods, you can maintain the confidentiality and security of a file, especially image files. In this study the algorithm and method used is the AES cryptographic algorithm (Advanced Encryption Standard) 256 and the LSB (Least Significant Bit) steganography method. Data integrity needs to be tested to ensure that the encryption and decryption processes are running properly. Data integrity testing uses the SHA-1 method. Likewise, the image quality after insertion will experience a decrease in quality. To evaluate this, it is necessary to test using the PSNR method. From the results of data integrity testing by comparing the hash value of the decrypted image file with the original image file, there is no difference. So this shows that the encryption and decryption process was successful. While in testing using the PSNR method, the average PSNR value is 44.14086 dB and with an average error value of 2.830403 dB, which means there is a small decrease in quality. From the implementation and testing results, it can be concluded that the AES 256 cryptographic algorithm and the steganography method LSB can be implemented in maintaining the confidentiality and security of secret messages.
