Learning is the process of interaction between teachers and students in educational institutions which aims to achieve the expected results, through educational interactions and the goals of knowledge, attitudes and skills. Teachers play an important role in learning by providing appropriate teaching materials. Current learning still prioritizes the role of the teacher and students' activities in class do not develop independently through discovery and thought processes. Therefore, to overcome this, learning resources that are integrated with information technology and based on student-centered learning models are needed. One model that can be applied to chemistry learning is the experiential learning model. This research is development research using a 4-D model. The research aims to produce an integrated augmented reality worksheet based on experiential learning on electrochemical cells material. The results of the LKPD validation by material and media validators were considered valid in terms of content suitability, experiential learning characteristic aspects, linguistic aspects, presentation aspects, graphic aspects, appearance aspects, and software utilization aspects with percentages of 98.87%, 100% respectively. , 87.5%, 96.87%, 96.87%, 97.22% and 100%.

Learning is an effort to provide stimulation, guidance, direction, and encouragement to students so that the learning process occurs which is characterized by changes in student behavior as a result of student interaction with the environment. The observation results explained that the 21st century skills possessed by students were still low. One of the causes of low 21st century skills possessed by students is the lack of active involvement of students in the learning process and the lack of orienting phenomena related to chemical concepts. Therefore, to develop 21st century skills, a learner-centered learning model such as Phenomenon based learning model is needed. This research is a development research using the 4-D model. The research aims to produce LKPD based on phenomenon based learning on colligative properties material. The results of e-module validation by material and media validators are considered very valid in terms of content feasibility, presentation aspects, linguistic aspects, graphical aspects, aspects of phenomenon-based learning characteristics, display aspects, and software utilization aspects with a percentage of 100%, 97.5%, 91.67%, 100%, 82.5%, 94% and 100% respectively. This LKPD is in the very valid range with a score of 94.74%, so this LKPD has been confirmed valid and can be tested.

Chemistry is to study the concepts which are mostly abstract. One of them is in colloidal material. The abstract concepts are difficult to understand if only explained in two-dimensional form. Therefore, a media is needed to visualize the abstract concepts of colloidal material both in terms of both macroscopic and microscopic. This study aims to develop an interactive learning media using Autoplay Media Studio 8 that is worthy of being used as a learning media. The study used the Research and Development (R & D) method which refered to the Borg and Gall model. Data collection techniques were in the form of validation sheets and response questionnaires (teachers and students). The data analysis technique used descriptive statistical analysis. The results show that the percentage score obtained from five experts (two media experts and three material experts) gained 96.74% with very valid categories. The results of trials for teachers and students each obtained an average percentage score of 87% and 92% with very practical categories. Based on the results of the study, it can be concluded that interactive learning media using Autoplay Media Studio 8 on chemistry subjects of colloid material in class XI SMA/MA are appropriate to be used as learning media.
