Kurikulum Merdeka Informatika Kelas 8 Bab 3: Teknologi Informasi dan Komunikasi

0:00 [Music] Hi everyone, welcome back to the education portal channel. On this occasion, we will discuss the summary of Informatics material for class 8 chapter 3, namely information and communication technology. This material is already in the Merdeka curriculum. Let's start with application software and application features. Application software or application programs are computer programs designed to perform certain tasks related to the operation of the computer itself. Applications are usually used by users who are usually

0:46 called and users. Applications are just programs that must be controlled by users. So, we as users must first know what the application is used for and what its purpose is. Now we will learn more about the contents of the application. In general, we start with application objects. Each application has a main object that is managed. For example, for word processing applications, it is used to manage documents that mainly consist of text on a page, it has a number of paragraphs, words, punctuation, etc. There is also a worksheet management application used to manage a set of worksheets in which

1:32 there are numbers, text, formulas, etc. There is also a presentation application used to manage a set of slides to present something to others, which mainly contains text, images, etc. Application objects will be arranged in a structured manner and have relationships with each other. Objects or pieces of objects from an application can be moved from one place to another. both inside or outside the program itself to move objects we can use the Cut or copy command and the main object of the application is processed temporarily in the open application window and

2:19 only when the application window is open when we close it then it disappears Therefore there is a save feature so we can save in the form of a file to be reopened later each file created by the application will certainly have different extensions yes For example files from word processing applications can be saved in dog dog xrtf odt format Or other files from spreadsheet processing applications can be saved in xls XLSX ods csv format or other formats files from presentation material processing applications can be saved in PPT pptx odp format or other formats

3:07 there are also image files with data presentations in the form of bitmaps so save in PNG BMP and JPEG formats in formats with data representation in the form of vectors can be saved in svg format then if the PDF file is a file in a portable format and can be processed by any application for pure text files only in a series of characters stored in txt or HTML format next we discuss the application features each application must have its own features that are tailored to user needs fortunately the interface of most applications is similar because it is GUI based

3:53 or graphical user interface Cut copy and pass feature is the most popular feature used from ancient times until now its history is inspired by traditional practices in editing typed manuscripts on a paper where people cut paragraphs from a page with scissors and paste them to another page in a computer application the Cut command moves text or other objects into the clipboard or buffer which is a temporary storage place the face command will move the object from the clipboard to the destination document the copy command will copy the highlighted text or other object into the clipboard and will move the object from the clipboard to the

4:39 destination document besides the 3 features there are also screenshot and snapping tools screenshot features are used to capture the screen on the Windows platform can use the print screen button then paste it into the active window Well later the results will appear according to the appearance of the window captured in various images the weakness of the result is that the entire screen will be captured and must be cropped or cut manually if you want only certain parts besides using screenshots we can also use snapping tools the function is the same for taking screenshots but more freedom in selecting the desired part next analysis of word processing applications

5:28 Well now we will analyze the contents of word processing applications in this chapter in this book there is Microsoft Word there are many objects that can we find in Microsoft Word we try to learn together yes this is too long here you can see here there is a table of objects explanation of characteristics and operations this explains in detail how each function and its use you can read yes Can try on the whale

6:15 Well next we go into the material of the Maya laboratory Maya laboratory is a laboratory that is made in Maya using a computer The first Maya laboratory was present with the name virtual laboratory of psychology in 1977 this laboratory continues to develop from physiology life sciences general sciences arts and literature in 2000 this project was included in the research project in experimentalization of life funded by the Fox Wagen foundation in 2002 the first version of the virtual laboratory online

7:05 but still has weaknesses yes Here is a comparison between Maya and physical laboratories you can see here there are advantages and disadvantages here if in Indonesia itself We also have a Maya laboratory you can access it at fillab.belajar.kemdikbud.go.id yes although when the admin accessed the site it couldn't Well if there are lots of other alternatives available on the internet such as the Mayapad laboratory novel Labs and the concord Well yes maybe That's enough thank you for watching the learning video until the end hopefully it will be useful for all of us don't forget to like Comment and subscribe
