Abstract—Child development at the early age requires a lot of
help from their teachers or parents, because children need guidance to get better understanding about their world. According to Piaget's theory, the child's cognitive development is divided into 4 stages, namely Sensorimotor (born - 2 years), Preoperational (2 - 7 years), Concrete Operational (7 - 11 years), and Formal Operation (more than 11 years). Based on interviews with child psychologists, during the Preoperational period, the child's cognitive development should be able to understand how the environment conditions (which have been achieved in the Sensorimotor period), such as understanding the existence of objects, understanding the time of rest at night, and others. Therefore in this period, the child is targeted to understand the problem solving experience, mathematical concepts, letter identification, form recognition, etc. So that during the concrete operational period, the child's is ready to learn when they attend elementary school, jigsaw puzzle is an alternative to enhance that ability. Game applications in mobile devices can be used as an alternative to children's learning. This research is done by Child-Centered Design approach to gain perspective in developing this game application. Testing using the Quality in Use Integrated Measurement (QUIM) model. The user experience model generated from the analysis will be implemented into a jigsaw puzzle game application with a good usability level. From data testing that has done, the result is low persona (85.3%), mid persona (94.5%), and high persona (92.4%).

Introduction
During childhood, children not only growing physically, but they are also growing mentally. They continue to advance their skills in observing and interacting with the world around them and also make tremendous leaps in how they process, store, and use information. According to Piaget's theory, the child's cognitive development is divided into 4 stages, namely Sensorimotor (born - 2 years), Preoperational (2 - 7 years), Concrete Operational (7 - 11 years), and Formal Operation (more than 11 years).
From the interview to the child psychologist, during the Preoperational period, the child should have been able to understand how the environmental conditions that have been achieved in the Sensorimotor period, such as
understanding the existence of objects, to understand the time of rest at night, and others. Therefore in this period, the child is targeted to understand the problem solving experience, mathematical concepts, letter identification, form recognition, etc. So that during the concrete operational period, the child's is ready to learn when they attend elementary school, jigsaw puzzle is an alternative to enhance that ability. Game applications in mobile devices can be used as an alternative to children's learning, because mobile games can be used anywhere and anytime compared to conventional games.
Based on the results of the survey to the children, using two puzzle game applications (Puzzle 4 kids & Super Puzzle), there are still some shortcomings. Usability aspects that have not been fulfilled are memorability and efficiency of use, thus affecting the user experience in early childhood, therefore evaluation is required to improve the user's task.
Children-Centered Design was used in this study to determine the needs of early childhood. So that can be generated user interface model and user experience model, for further testing to the early child to measure the usability level of the resulting prototype. Testing is done using QUIM (Quality in Use Integrated Measurement), this is because the aspects of QUIM are dynamic so that the criteria to be used can adjust the needs.
Literature Study
Piaget Theory
Jean Piaget was a Swiss clinical psychologist known for his pioneering work in cognitive child development. Purpose of theory is to explain the mechanism of the child from birth to teenage kids. Cognitive development is a process reorganizatio of the hild s e tal as result of biology maturity and experience to the environment. There is 4 steps of cognitive child development, that is Sensorimotor (birth to 2 yo), Pre Operational (2-7 yo), Concrete Operational (7-11 yo), and Formal Operation (>11 yo). [1], [5]
User interface
User interface is the all components of an interactive system that provide information and controls for the user to accomplish specific tasks with the interactive system. [18]

User Experience
The perso s per eptions and responses resulting from the use on anticipated use of a product, system, or services. User e perie e i ludes all the users emotions, beliefs, preferences, perceptions, and behaviors.[18]
Jigsaw Puzzle
Jigsaw puzzle is traditional game that exists since 1800s. In the beginning, the puzzle is made from wood plain that drawn then cuts into pieces. Jigsaw puzzle can reduce Alzheimer disease. According psychologist, jigsaw puzzle is needed by kids at age betwen 3-7.[13] Because, they difficult to color and shape recognition and jigsaw puzzle can help child to solve those problems.
Children-Centered Design
Children-centered design is part of User-centered design in children context.[4] There s step i this ethods, that is
Fig 1 Children-centered design [4]
1) Specify Context of Use
Start ith ide tif i g the people ho ill use our product, what they will use it for, and under what
o ditio s the ill use it . I ase of CCD, these
people are children. To understand the context of use, we have to do some field research. Interview to parents, teachers, and other adults that can tell you about children habits.
2) Specify Requirements
Observe the objects or engage them in a conversation to get more specific insights. In this step, we need to gather requirements, include business requirements and user goals.
3) Create Solution Design
Based on all the insights you gained from your context analysis and considering your product requirements, we can create solution design for the products.
4) Evaluate
Evaluate the design through user testing your target audience. In this case, there is no way around getting together with your target group to find out if there are any unexpected issues. When designing for children, it is not only important that your product is easy to use
for your target age group, it also has to be fun and engaging.
Persona
The purpose of persona is to create real representation and can be belief as a main reference of the user group. Representation must be based on qualitative and quantitative from user research and web analytics.[15]
Mental Model
Mental model is user beliefs of doing on the system or concept. The belief is developed by habit and behavior based on daily activity of the target users.[16] Basically, mental model represents user activity when doing with the system. When create mental model we have to understand the system clearly to get best result.
Conceptual Model
Conceptual model is structured concept when developing system. Developing model is made based on the user and needs of the system.[16] Conceptual model is a technical form that can be learned and used for the next step of developing process.
QUIM (Quality in Use Integrated
Measurement)
QUIM is a hierarchical methods for analyze usability into factors, criteria, and metrics. Model can be used for create quality of the requirements as well as identifying, implementing, analyzing, and validating product quality by metrics.[11] There are ten factors in QUIM, consist of Efficiency, Effectiveness, Productivity, Satisfaction, Learnability, Safety, Trustfulness, Accessibility, Universality, and Usefulness.
120
Interview
Interview is a verbal communication and face to face with the research objects for some reason, it is occur because we will gather data more completely, includes feels, experiences, emotions, motives, etc.[17] On this research, we use inter ie to the user just a s er it Yes or No . “o that makes child answer easily. Every answer has a value and calculated by each factor. There is example calculation on the table below.
Table ii Example Calculation
Example: Efficiency No Question Yes No 1 Question 1 0,2 2 Question 2 0,2 3 Question 3 0,2 4 Question 4 0,25 5 Question 5 0,2 Total 1
After that, data will be averaged with equation (1).
(1) With xi = sample value to i fi = frequent value to i n = total sample
Validation
Validation is trustfulness of the research measurement. There is many types of validation, the one of them is facing validation, that is validation is being tested by expert.[17] Validation can be used as a measure on the research by qualitative and quantitative. On the qualitative research is usually used in object like social, habit, and behavior.
Modelling
In this section will be explained about every activity in each step when researching. Here is the flow of the each steps.
Fig 2 Child Centered Design Methodology
Interview Child Psychologist
In the beginning of the research is doing interview to the child psychologist to find reference what abilities need to be improved. Interview occur at Biro Konsultasi Psikologi Dwipayana – Jl. Panaitan 15, Bandung, Indonesia.
There is 5 abilities that need to improve, that is gross motor, fine motor, cognitive, social, and religion. And there is many ways to develop each abilities, especially in cognitive ability can be improved by puzzle game.
Specify Context of Use
Gathering data to get specifying context of use by observation and interview parents and teachers. Interviewing parents happened to get the future product is safe by the age and interviewing teachers to get the future product can be used for learning.
Interview is occurred in TK Taruna Bakti and TK Islam RA PERSIS 8. From interviewing teachers, we get information that children at age between 4-6 yo turns out close to the mobile devices. Evidently, there is extracurricular computer in their school. The teachers wants that the future product might have to contain the things around kids, like animals, furniture, transportation, etc. Different from teachers, parents want future product might have to contain cartoon which their kids like.
After that, research is going to observe and interview the children. Observation is occurred in TK Dhiyaul Haq – Sukapura by playing jigsaw puzzle in a board (3x3 – 9 pieces) and mobile device (Animals Puzzle for Kids) which downloaded from Play Store.
From the observation will be got user personas which divided into three types (i.e. Low, Mid, and High). The following persona obtained.

Specify Requirements
In this section will be explained about modelling user experience. By persona, we get user limitation while playing puzzle game. User limitation will be defined into needs and goals. The following user requirements explains below.
Table vi User Requirements
No Persona Goals Requirements 1 Children a)Practicing cognitive ability b)Get to know about things around a)Give score by time as a feature b)Give category which related with the things around
No Persona Goals Requirements c)Pronounce name of the things d)Spelling name of the things e)Wants play with what cartoon they like f)Understanding playing puzzle on smartphone g)Interacted with puzzle game on smartphone c)Give pronounce feature d)Give spelling feature e)Categorize puzzle by its gender f)Give tutorial feature g)Give female/male character Mental Model
At the time of researching, we get mental model from target user. Mental model is user beliefs of doing on the system or concept. Model is represented in flowchart.
122
Fig 3 Mental Model
Hierarchical Task Analysis
From mental model which made above, the model will be identified and create into HTA.
Fig 4 Hierachical Task Analysis
After that, modelling user experience is begun. Model is started by scenario user experience and conceptual model. On scenario, model will be set into tasks, goals, description, and information. And on the conceptual model will be set into technical information, such as task arrangement, respons each task, and element that used in the task.
Create Solution Design
We created the solution in many software by adobe, such as Adobe Illustrator, Adobe Photoshop, and Adobe Audition. Then develop the design into prototype with Unity 3D.
Evaluate Design
Evaluate the design is began by define question, test plan, test scenario, and processing data. QUIM model is used to calculate data testing.
Define Question
Questions is defined from QUIM factors. There is ten factors of QUIM, such as Efficiency, Effectiveness, Satisfaction, Productivity, Learnability, Safety, Trustfulness, Accessibility, Universality, and Usefulness, these factors have a several criteria to define what need to gather from research objects. Each factors will be define into a few questions. And every question asked and
a s er ith Yes or No . The answer has a each value that suitable with its factors and criteria.
Test planning
Prototype which made will be tested to 15 childrens, with each 5 childrens for low persona, mid persona, and high persona. Testing is occurred in TK Dhiyaul Haq – Sukapura.
123
Test Scenario
Testing prototype is done with the following steps. a) Prepared smartphone which installed the
prototype
b) User choose the icon application (Kiddo Puzzle) on screen
c) User is playing the game from beginning to the end for 10 minutes
d) Doing interview from the question which defined before
e) Doing summarize data into digital and calculate
