1. Introduction

Engineering Faculty is one of many Faculty in Jakarta State University which has some course of study, and one of those courses is Electronic Engineering Education. Based on the book BPA UNJ, Electronic Engineering Education main purpose is to prepare Graduated Students with high capability to become teacher in Vocational High School. In addition, the graduate student also can work on industry, Hence, to prepare the student to enter the world of work (both of as teacher or working in Industry) the quality of knowledge both Theory and Practical should be good, right and quality. One of indicator's quality for education is graduates who mostly produced having knowledge, skill and good manners. This quality can be seen with mostly student graduate in time and obtain index achievement good. In equip graduate knowledge and skill in the study Electronic Engineering Education there are some engineering lecture, and one of them is Industrial Electronics (ELIN). In order the students each have the skills in the psychomotor, good manners and morals they need materials and equipment or private practice the same amount as the students.

Digital Games are becoming a new form of interactive content and game playing provides an interactive and collaborative platform for learning purposes. Games provide a context where participants are continually challenged and confronted with increasingly difficult problems as they progress. The use of game as a medium learning can work for some device technology one of them is a smart phone. Application mobile Game Based Learning (mGBL) built in line with the rate education and also adjusted to the curriculum apply. Mobile game as a medium learning can be improved and be utilized in accordance with the learning design. Mobile game be able to support the creation of the new learning, effective, and pleasing to achieve goals learning.

Digital mobile game-based learning is the product of a balance between learning and gaming elements (Mehran, Fattaneh dan Saeed: 2018). In the other words, entertaining intrinsic of games has potentials to be coupled with the learning process and improve it. Therefore, two important elements of educational games are entertainment and educational component separating educational games from entertaining games and e-learning applications.

The development of game ELIN in mGBL is conducted in ordered and in accordance into each step.

The outcome of the investigations resulted in game ELIN in that way could be used as Lab Learning Media. This chapter will conclude that ELIN game can be used as Lab Learning Media for Electronic Engineering Education.

2. Methods and Equipment

Methods

Game development method

Development Model as a reference development of ELIN game is using R&D Method (Research & Development) with model MDLC (Multimedia Development Life Cycle. The stage for this development is:

  • Concept StageAt this stage do identification and estimate the needs resulting from observations on a research and do analyze about media technology

  • Design/Planning StageIn the planning stages using three stage whose are used before make the notation game that is DFD (Data Flow Diagram) and Storyboard. Analyze Method that used to build this educational game application is procedural Model.

  • Collect Data StageAt this stage, the matter related to teaching material/learning material obtained from interview to Lecturer of Industrial Electronics. Existing Matter refer to a curriculum that provided.

  • AssemblyThe assembly (making) is the stage in which all material objects or multimedia made. Making an application based on Data Flow Diagram (DFD) and storyboard. All objects or material made and combined into one whole application.

  • TestingThis stage called equally testing stage alpha (alpha test) where testing done by the maker of the application or environment its own maker. Testing alpha including functional test, feasibility test by Lecture Expert and Media Expert. Next up betha testing. Testing betha including respondent test and T-Test.

  • DistributionAt this stage, applications that has been completed tested and was declare as a good purpose, will be distributed to VIIA Class students in SMPN 269 Jakarta.

Data collection method

The technique of data collection is the main step in a study, because the main objective of the study is to get the data (Sugiyono, 2016: 137). The technique of collecting data which used in this research were:

  • Observation Method. Observation done to obtain data that support the study

  • Interview Method. In this method interview used to get information through lecturers about the curriculum and obstacle in learning.

  • Questionnaire Method. The survey given to media experts to know feasibility of media in learning process, and to lecturer expert to know feasibility of material. Data of student response during learning taken with questionnaire survey about the use of game ELIN in Industrial Electronic Lecture.

Data analysis method

In this research, there are 4 kind of data there are validation instrument by experts, validation matter by expert, validation media learning by experts, the survey/the questionnaire response by students.

  • An Analysis Data result of Validation InstrumentsValidation instrument is done to know how much instrument can measuring the object to be observed. Validation instrument test is using Lawshe's CVR (Content Validity Ratio)Method and CVI (Content Validity Index). Lawshe (1975) proposes that each of SME (Subject Matter Experts) to answer question for each item with three option named: (1) Essential, (2) Useful but not Essential, (3) Not Required. Lawshe validity according to the formula used to analyze or counting each item: Note: CVR = Content Validity Ratio, nε = quantities of Experts who answer Essensial, N=total of Experts.After count CVR (Content Validity Ratio) the next step is to calculate CVI (Content Validity Index) from all of question. CVI (Content Validity Index) calculated based on the average of CVR (Content Validity Ratio). Formula to calculated CVI (Content Validity Index) is: Note: CVR = Content Validity Ratio Total

The result of CVI calculated has ratio from 0 to 1 which can categorize based on CVI value. CVI Value table can be seen as below:

Table 1

CVI Calculated Ratio.


No. Category Ratio
1 Not Suitable 0 – 0,33
2 Suitable 0,34 – 0,67
3 Very Suitable 0,68 - 1
  • An Analysis Data Result from Lecture Expert & Media ExpertThe survey that used to test the feasibility by Media Expert and Material Expert are using Guttman scale with two options, 1 as YES and 0 as NO. Guttman Scale used because it requires firm answer is learning media eligible for use or no. The results of the survey on every aspect must have answer yes to be announced eligible for use, if there was a no answers these aspects must be resolved. The validation data instrument from two Experts will be analysis using Coefficient Contain formula by Gregory with the aspect judge by expert (Retnawati, 2016: 32). Before counting the validity of the instrument and the near future after receiving the data from the answers of the each of an instrument who were judged to be, the answers need to arranged beforehand with prepare contingency table to calculate the Gregory Index. Contingency Table to calculate the Gregory Index to be demonstrated at tables as below:

Table 2

Contingency Table to Calculate Gregory Index.


Ahli 1
Poor Strong
Ahli 2 Poor A B
Strong C D

After get the data from experts, move the data into Contingency Table by compared the corpuscular list of two expert with relevancy category strong with all corpuscular list (to grouping the strong and the poor one). The score for each answer can be calculated with formula:

Coefficient of Content Validity =DA+B+C+D

Note:

A = the answer of one expert NO and the other one NO as well (Poor-Poor)

B = the answer of one expert YES and the other one NO (Strong-Poor)

C = the answer of one expert NO and the other one YES (Poor-Strong)

D = the answer of one expert YES and the other one YES as well (Strong-Strong)

The next step is the result of calculation that has coefficient of the validity interpreted it into the Agreement Expert index (Retnawati, 2016: 33). Table Agreement Expert Index can be show below:

Table 3

Table Agreement Expert Index.


No Percentage Category
1 < 0,4 Low Validity
2 0,4-0,8 Enough Validity
3 > 0,8 High Validity
  • An Analysis from Questionnaire Survey to RespondentsThe survey given to students as a respondent used Likert Formula which consist of five options (Akdon, 2012:21) as shown in the table:

Table 4

Criteria for Respondent Questionnaire using Likert Formula.


No. Criteria Score
Positive Negative
1 SS/ Very Agree 5 1
2 ST/ Agree 4 2
3 CS/ Not so Agree 3 3
4 TS/ Not Agree 2 4
5 STS / Not Really Agree 1 5

The data was obtained from respondents watchful such students analyzed in order to know how student's response about education media ELIN game that has been used, do education media ELIN game useful or not.

In the collection data method will be used 3 steps before made the Notation Block games there are Context Data, Data Flow Diagram (DFD) and storyboard. Analysis Modelling approach that used to prepare the education game is procedural modelling. This software will used Data Flow Diagram (DFD).

  • Context Diagram. Context diagram is a diagram which draw input, process and output as global which happen in the on-software system whose will made. The context diagram of this ELIN Game can be seen in the picture

  • Data Flow Diagram (DFD). Data flow diagram (DFD) is a technique which draw the data and information which used as a travel data from input to output. DFD made if the contex diagram still need any more process that need more explanation. This Data Flow Diagram of this ELIN game can be seen in the picture.

  • Storyboard. In this stage we did planning the layout and prepare sketch design as a storyboard which show the product start from opening, main menu which show sub menu learning and play till the last level of the game till the end. The good layout will make an interesting game.

Data collection stage

In this stage we will prepare all the data we need, such a material, animation picture, audio and video. The material we need for this ELIN game is based on Curriculum of Industrial Electronics study.

Assembly stage

The assembly is stage where whole object multimedia built upon storyboard and structure navigation derived from the design. At this stage we used some software in manufacturing namely adobe illustrator, adobe photoshop cc14, mix craft pro studio 6 and adobe after effect cc14 for making illustration, audio and video, and programming. This stage is stages by which product ready to be operated consisting of explanation for the environment and the implementation of the program. The support application to be applied to the environment, so in this case must consider specifications hardware and software in making the ELIN game.

Testing stage

  • Media ImplantationIn this stage, media that prepare by storyboard which has been planned in the design stage. ELIN Game Education as a learning media has some contents and display, there are: content, opening page, main page, playing page and exit from game.

  • Product FeasibilityThe product that has been develop will be test the feasibility before implantation the media as a learning media to the students of Electronic Engineering Education. It has 2 tests to know the feasibility of the ELIN game as a learning media, which is Functional Test and Expert Test.

  • Functional Test Result (Black Box)Base on the Black Box Test will get the result which function can running well and based on the command input.

  • Expert Test ResultThe software which has prepared then will be doing the test by experts, Lecture Expert and Media Expert. Both of the test will be done to know if the media already feasibility or need more revision. Based on the feasibility test by both experts, will get expert validity coefficient value 1, this result is a high validity. After get the conclusion as a feasibility game, the next step is ELIN Game will be test to students, and will get the percentage of feasibility product as whole 89%, which conclude that ELIN game is “VERY SUITABLE” for Learning Media in Industrial Electronic Lab Study.
