Technology is very helpful for simplifying work and daily needs and provides a variety of entertainment for those who want it. For this reason, the community is required to make a change in every activity. The teacher's learning process at Tunas Harapan Kindergarten, which is located at Limbangan Village Rt 02 Rw 04 Banyu Putih District, uses paper media that is attached to the wall or uses teaching aids in delivering learning materials that have not used learning technology. Thus, children feel bored and sometimes neglect to pay attention to the teacher's explanation, and sometimes the learning process is very dependent on the delivery of material delivered by the teacher directly. For this reason, providing support for interactive learning is to take advantage of the existence of media learning facilities that use technology-based mobile education. The application of the learning model with the STEAM method in the learning activities of children aged 5 to 6 years, one of which is the development of student creativity. In building mobile education in interactive learning for early childhood to present or introduce mobile-based education technology to children from an early age, in independent learning it is easily accessible outside class hours and assisting teachers in teaching in particular.

Abstract Catfish is one of the important strategic commodities in Indonesia which is widely cultivated. Catfish needs continue to increase along with the increasing demand for catfish as foodstuffs such as the need for many lamongan stalls. However, efforts to increase production and development of catfish farming have several obstacles that can reduce production by 50% due to certain diseases. This situation is certainly very detrimental to the catfish in particular and the wider community in general. However, farmers have very low knowledge about the technical maintenance of catfish plants. This situation resulted in farmers being highly dependent on the control of a limited number of plant pests. To overcome this problem, a website-based application was made. To optimize computational resources on mobile devices, we need a Cased Base reasoning method that consists of frame based and rule based representation with rules or rules that are used to determine whether catfish plants contract certain diseases, which types of diseases can be detected in the process this research includes bacterial pustular disease, interchnose disease, mosaic virus disease, collapsing disease, rust disease and blight disease. then analyzed which cased base reasoning is the most optimal. This can be done with a scenario comparing some of the cased base reasoning from the level of accuracy at 87.5%.

The development of reading learning carried out at Cut Nyak Dien Kindergarten which is located at Surokonto Wetan Village, RT. 03/RW. 03 district. Pageruyung Kab. Kendal. The ongoing learning process still uses manual or conventional methods by using posters in the form of cardboard. The limited media used in learning causes teachers to need to explain repeatedly using teaching aids. When viewed from the media used, namely cardboard, the images that will be conveyed are less attractive to children in studying the images. This is because children still have difficulty in pronouncing letters and connecting pictures with words. One of the supporting factors for interactive learning is by utilizing game media for learning facilities using mobile education-based technology. The purpose of making and developing educational games is to attract children's attention to play games that function as learning media. One of them is to improve children's language skills. Language development is part of the abilities that must be possessed by children. One of the language skills that must be developed is the ability to read, because by reading children can understand the meaning of words and sentences, and understand that there is a relationship between spoken and written language. The application of educational games in classroom learning with the inquiry learning method in the simplest explanation is a form of approach that is oriented to early childhood. Where the teacher only gives direction and then students are able to realize their learning and thinking abilities. In this method, children play an active role in learning. Researchers need to solve this problem with the ADDIE method, namely by analysis, design, development, implementation and evaluation. The data collection technique is using a questionnaire. The results of the validation of interactive game development can be concluded that interactive games to improve early childhood reading skills are valid, practical, and effective

Various parties in the customization chain such as device vendors such as Samsung, Xiaomi, Oppo, Huawei, and others, operators such as Telkomsel, Smartfren, XL, etc., and hardware manufacturers can customize one or more layers to adapt devices for different purposes, such as supporting specific hardware and providing different interfaces and services. The purpose of this study was to investigate systematically for any inconsistencies that arose as a result of the processes involved in this study and to assess their various security implications. This research runs DroidDiff to perform a substantial-balance diverse investigation on images collected by the analytical methodology. DroidDiff found a lot of differences when it comes to the selected features. The method used in this study is the method of five differential analysis algorithms. As a result, by comparing the security configurations of similar figures, important security changes that could be accidentally introduced during customization can be found. The results show that DroidDiﬀ can be used by vendors to check the configuration of various security features in a given image. DroidDiff will extract those features from the image, and compare them to other image configuration sets, then DroidDiff will flag the inconsistent ones for further investigation by vendors who have the source code and tools to check their effect. For future work, improvements to DroidDiﬀ to more accurately detect risky inconsistencies are highly recommended. Improving DroidDiff will help reduce the number of false positives and determine risky configurations more accurately.
