The essentialist school of philosophy is a school of philosophy that wants humans to return to their old culture. The emergence of this ideology was a reaction to the absolute and dogmatic symbolism of the Middle Ages. In this way, a systematic and comprehensive concept regarding humans and the universe is formed that is in accordance with the needs of the times. This essentialism assumes that education based on the core belief in flexibility in all its forms can produce views that are easily changed, easily swayed, directionless, and less stable. Therefore, education must be based on values that are stable, proven, long-term, and have values that enable a country's education to remain stable and focused. The aim of the essentialist educational philosophy is to improve the character of society through existing cultural heritage, so that later students can contribute to improving social life in the face of changing times that can damage character values. The purpose of this paper is to examine the philosophy of essentialism from the perspective of Islamic education using library research methods. Based on the research results, it is stated that essentialist schools have a view of the field of education, namely educational goals, educational curriculum, educators, students and the environment. Apart from that, there are several views that can be used as measuring tools and should be taken seriously. These are the ontological view, epistemological view and axiomatic view.

In the online buying and selling process, the seller becomes the name of the store and the buyer does not know the identity of the seller such as name, address, and even age. Buyers will only know from the name of the store selling the item. The concept of online buying and selling is that you only have information about the name and address of the store, but do not know who the owner of the store is. In the buying and selling process, the buyer chooses the product available in the store and if there are any questions about the product, they can ask the seller via chat. The seller then uses a robotic or human system to answer the buyer's questions. The second pillar and condition is ma'qud 'alaih or a medium of exchange and goods sold. The medium of exchange used in the buying and selling process, both online and offline, still uses the same tool, namely money. The purchase or payment process for online buying and selling can be done through bank transfer through the payment code number that has been ordered. The majority of online stores also offer a wider selection of different types of goods.

This research was motivated by researchers' anxiety regarding the reduced attention of teachers to the importance of developing image building in Islamic schools. Image building or image formation, especially in educational institutions, plays an important role in building a school's reputation and increasing public trust and participation. However, the phenomenon observed by researchers shows that many teachers at Madrasah Aliyah pay little attention to this aspect, which can have an impact on public perception of the quality of the education provided. Therefore, this research aims to further explore teacher strategies in developing image building at Madrasah Aliyah Al-Islam Joresan Mlarak Ponorogo. The type of research used is qualitative field study using interview and observation data collection methods. The results of this research found that teachers' strategies in developing image building at Madrasah Aliyah Al-Islam Joresan include using the principle "al-muhafadhotu 'ala qodimis sholih wal akhdzu bil jadidil ashlah" which means "maintaining (maintaining) old values ??or teachings good and adopt new and better values ??or teachings," and empowering the environmental community at Madrasah Aliyah Al-Islam through teacher direction by the school principal.
