INTRODUCTION
Education is important to every human being. According to research conducted by Sujana (2019), the functions and objectives of education in Indonesia play a role to create a society of high integrity and a generation of experts and skilled in each study. The potential that can be developed optimally in human beings is the physical, intellectual, emotional, social and spiritual aspects with the stage of development supported by the surrounding environment.
Physics learns about the knowledge of the universe that requires reasoning and the ability to think, to support the evolution and curiosity of students. Physics is difficult by presenting formulas as a vocabulary understanding and it feels boring when studying materials that are comfortable. In increase to the next problem, there are few interesting and motivating learning media in physics subjects. Interesting media and close to students are able to improve the mastery of concepts. Packaging of quality and informative materials supports the strengthening of student understanding With reference to the development of multimedia-based learning media, qualified educators and creativity can provide a treat of student learning motivation increased (Riskiawan, 2016). One of the materials of global warming is an increase in average temperatures on land, oceans and air that results in extreme weather intensity. The selection of global warming materials is considered in accordance with the consideration of the rising concentration of greenhouse gases in the surrounding environment, especially in industrial areas. In increase, farmers receive a decrease in crop yields both quantity and quality of products so as to affect the selling price of the market. From this phenomenon is very concerned for the future of the earth and humans, therefore it is necessary to make changes by studying global warming material to review how the causes and effects of global warming. Along with the individual consciousness of the importance of education and character that cannot be separated from daily life there is also the development of technology and information that can be the best place to channel various information.
In the development of technology and information in today's digital era has an influence on life in various fields, especially education. Positive development that must be utilized for educators by analyzing the right technology as a teaching medium can assemble the criteria of learning media. This can help online learning activities that are conducted in each student's home during the current pandemic. Online learning is done in each student's home, according to the interests of learning students, but at times like this student and the diamonds must comply with the protocol to take care of each other's health. More innovation and creativity are required in order to increase the quality and quantity of students in learning. Students are considered able to be interested in online learning if done at school or not at home in order to be friends to study sounds group Sundus (2020). Supported by Mustari (2019), the development of digital learning media on global warming materials deserves to be used in the classroom by having an appeal that gets students motivated to learn more quality. The use of digital platforms can be used for every student, but has weaknesses in the limited internet networks that enter into certain areas and not every student has an internet data package (Andi, 2020). The development of IPRO digital technology, media provides solutions to current educational problems by utilizing powerpoints and androids. This media can be accessed without using the internet net so that students can learn quietly without having to think about networking and focus on learning. In addition, it can be accessed at any time when students take part in learning and real learners. With Microsoft PowerPoint which is a software to exhibit information in written form, animation, video or audio. According to certain (2020), learning using animation can improve the representation of students' understanding in understanding learning rather than not using animation as a material delivery tool. Equipped with hyperlink features, and transitions. Everything, there are advantages and disadvantages, PowerPoint have a drawback in accessing done on the Microsoft platform, animations are less interesting and the documents displayed sometimes mess with different versions. Innovation in the utilization of PowerPoint and android applications can help achieve learning targets along with mastery of teachers in usage (Nurhidayati, 2019).
Interactive learning media can improve the understanding of concepts with media that has been validated by experts so as not to cause poisoning in media users. The effectiveness of the media can be known through the positive response of students so that it is suitable to be applied in physics learning materials (Inung, 2018). Android-based interactive media can realize interaction between users and applications just like students in interacting directly with learning media. The advantages with such media can minimize the problem that often occurs is not carrying textbooks while in school or can help self-study at home (Roni, 2020). Based on the description that has been presented, researchers are interested in researching the development of learning media that can help students to understand the material of global warming. Researchers hope this learning medium can build a two-way interaction between students and computers or androids. Researchers hope to improve students' interactive physics learning process, in addition to motivating students to maintain the environment such as the application of global warming materials. According to Yani's research (2020) about the motivation of online learning by reviewing from the aspect of conveying ideas or ideas have five categories one of them with initial capital that is curiosity. The first category can generate high learning spirit and motivation to get a description of the questions presented. The researcher's goal is titled IPRO High School Physics Learning Media Development (Interactive PowerPoint Presentation) Based animation on Global Warming Materials to describe the validity of learning media development and describe the effectiveness of IPRO learning media on global warming materials.
