Introduction
Concept of colloids is part of chemistry closely related to everyday life, for example in industrial chemistry, on the manufacture of various products such as cosmetics, food ingredients, and a number of other products [1]. In colloid material usually students are required to memorize it, without applying it in everyday life [2]. With the difficulties of students applying colloid material in everyday life, it demands teachers to be creative and innovative, one of which makes a media of learning [3]. The growing technology demands teachers to be able to use technology to create and develop the learning media in accordance with technological developments. [4] Implementation of IT in a field of learning is believed to be able to improve student's learning ability [5]. Learning process by implementing IT will provide the learning materials using various media that will affect the student's learning achievement in a positive way [6]. Learning using multimedia has a positive effect on students' learning outcomes [7]. One example of IT implementation in a field of learning is the making of the educational games.
The making of the game is very important; especially apply it in learning because it will improve the learning outcomes and the students' involvement [8]. One of the technological developments that are currently in demand by many people are smartphones based android. Because smartphones are easier to use, have an open operating system that allows smartphone users can add a variety of applications. [9]. This educational game can be very motivating while still maintaining or even improving the effects of education on the students [10]. Chemical learning on colloid material can be achieved well if the teacher uses the right learning media Thus, we need efforts to develop the android-based learning media. This paper reports on how to manufacture android-based educational games on a colloidal material to develop students' chemical literacy.

There were six stages in making the android-based educational game media in colloidal materials: (1) analysis of SK and KD of the collodial materials, (2) making process of the android-based educational game media, (3) revision of the android-based educational game media, (4) limited trials, (5) data analysis, and (6) production of the android-based educational game media in the colloidal materials.

Result and Discussion
The making process of android-based educational game media in colloidal materials uses research and development. This research method used to produce and examine validity of a particular product [11]. Some phases are conducted in this process. The first stage is analysis of colloidal materials, which aims to plan the sequences of learning process because it plays an important role in learning meaning [12].
In designing stage, the elements needed are integrated in the form of colloidal game by noticing the flowchart and storyboard. Flowchart used to describe the flow from one scene to another which eases the user to operate this colloidal game. The making process of android-based educational game media in colloidal materials is based on the designing stage, such as storyboard and flowchart [13].
The description of scenes, visual and audio design, information, and voice of narration will be made in storyboard stage. Software in this program uses programming language c# c++. After that, the educational game is saved in *.apk format in order to use in android smartphone.
The following is the visualization from android-based educational game media in colloidal materials after finishing some stages.
