INTRODUCTION
In the implementation of the learning process in schools, in general, various problems arise that affect students (as subjects of the school education system) to achieve the educational goals that have been set. One of the problems faced in learning in schools is the low creativity and interest in students' learning.
Education has an important role in improving the quality of human resources such as social, spiritual, intellectual and professional abilities, humans who have good quality are the main force in successful development. This is in accordance with Law no. 20 of 2003 Article 1 concerning the National Education System which states that: "Education is a conscious and planned effort to create a learning atmosphere and learning process so that students actively develop their potential to have religious spiritual strength, self-control, personality, intelligence, noble character. , as well as the skills needed by himself, society, nation and state". The law interprets that education has an important role in developing all the potential that exists in every human being, in order to create human qualities that are faithful, devoted, creative and independent. Educational institutions, especially schools, are responsible for implementing quality learning in order to achieve the educational goals set out in the law.
Based on the initial observations made, there are symptoms that are still not optimal student learning achievement. This can be seen from the learning outcomes obtained by students in the economics subject of class XI IPS SMA Ekasakti Padang, there are still many students who have not reached the predetermined target for Economics subjects, the minimum completeness criteria (KKM) is 78. Based on the table above, it is known that the learning achievement of grade XI IPS students at SMA Ekasakti Padang is still not optimal, because the KKM standard is at 78 and there are still scores below the standard of completeness and not yet reach KKM. Out of 38 students, around 22 students (57.89%) have met the KKM. Meanwhile, there are still around 16 students (42.11%) whose learning achievement has not yet reached the KKM limit.
The low learning achievement of students which causes the factors that affect a person's learning achievement are classified into factors from within students, namely physiological and psychological factors and factors from outside students, namely social and non-social factors. In addition, there are several other factors that can affect learning outcomes such as teacher factors, student factors, facilities and infrastructure factors, and environmental factors.
From the factors that have been explained, it is necessary to see which factor is more dominant in influencing student learning achievement, based on observations from observations that have been made at SMA Ekasakti Padang, about the number of students who are below the KKM score caused by several factors, one of them is the lack of student creativity in learning. Seen during the lesson, some students tend to be passive, indifferent, do other tasks and look for their respective activities, and students tend to wait for all information from the teacher, besides that students are also less confident either asking questions, responding to friends' questions, or convey ideas when the teaching and learning process occurs.
Creativity is a person's ability to produce compositions, products, or ideas that are basically new, and previously unknown to the creator. It can be in the form of imaginative activities or synthesis of thoughts, the results of which are not only summaries but have a purpose or purpose, not mere fantasy. By being creative, a person can actualize himself, something that is a basic human need today. People who usually manifest themselves are people who successfully develop and use all their talents and abilities so that they can enrich the quality of their lives.
Interest is a sense of liking and a sense of attachment to a thing or activity, without anyone telling. Interest is a psychological aspect that grows in a person, so that with the emergence of interest there will be a tendency in that person to like, have and learn about what he is interested in. In other words, if students do not have an interest in the learning process, the learning outcomes obtained by these students will not be optimal compared to students who have a high interest in learning in these subjects.
Good learning achievement is not only influenced by motivational factors, creativity that comes from within (intrinsic), but is also influenced by factors that come from outside (extrinsic). Thus, interest in learning is closely related to the way students learn. An active way of learning will make it easier for students to master the subject matter, if students easily master the subject matter, student learning outcomes will increase. Thus it can be said that interest in learning has an important position in supporting the teaching and learning process in schools.

METHOD
This research is a descriptive study with a quantitative approach. According to Sugiyono (2012: 8) "Research methods based on the philosophy of positivism are used to examine certain populations or samples, collect data using research instruments, and analyze quantitative/statistical data, with the aim of testing predetermined hypotheses".
The instrument used in this study was a questionnaire where the validity and reliability of this questionnaire were tested. Of the 30 creativity items, there are 22 items that are valid and 8 items that are not valid, while the interest in learning from the 30 items contains 23 items that are valid, while those that are not valid are 7 items.
The description of the data is done to determine the position of the data in a group. The description aims to reveal the mean, mode, median, variance and standard deviation in order to describe the distribution of the data and the level of achievement. To describe the data used descriptive statistical analysis techniques. This research was conducted on students of class IX IPS SMA Ekasakti Padang.
To determine the level of achievement of respondents in each variable, the formula is used: To test the requirements for analysis, several tests are carried out: (1) Normality test using the Liliefors Kolmogrof Smirnov test, (2) Linearity test (3) Multicollinearity test by looking at the Variance Inflation Factor is carried out with the help of SPSS version 22 . Hypothesis 1 and 2 tests are used to prove the truth of hypotheses 1 and 2 that have been formulated, the results of which will be used as conclusions for the research that has been carried out. The technique used to test hypotheses 1 and 2 is a simple linear regression technique. In general, Ghozali (2005) formulates the statistical (partial) t-test as follows: Description: t = Following the function with degrees of freedom Sb = Standard standard b = Regression coefficient If t count > t table then the data is significant at = 0.05 with degrees of freedom (df) = nk-1. Hypothesis 3 test is used to prove the truth of hypothesis 3 that has been formulated, the results of which will be used as the conclusion of the research that has been done. The technique used to test hypothesis 3 is multiple regression technique with F test (simultaneous). To prove the relationship of all independent variables to the dependent variable together, namely variables X 1 and X 2 against Y is used the F test formula quoted from (Riduwan, 2008: 142), which is as follows: Where: F = calculated F value R 2 = Determination/regression coefficient value k = Number of independent variables n = Number of samples To see The percentage of the contribution/influence of variable X to variable Y is used the coefficient of determination formula (Riduwan 2008: 139).

RESULTS AND DISCUSSION Descriptive Results of Research
Variables Creativity variable data was collected through a questionnaire consisting of 22 statements and learning interest consisted of 23 statements and Interest variable data was collected through a questionnaire consisting of 23 items which had been tested for validity and reliability. Furthermore, a questionnaire was given to 38 respondents to be filled in. Statistical calculations, while learning achievement was obtained from the final grades of the semester and the results of statistical calculations can be seen in the table below.

Creativity
Based on the table above, the research data obtained the lowest (minimum) 79 and highest (maximum) 106, average (mean) 90.55, middle score (median) 90, 50, the score that appears a lot (mode) is 82, and the standard deviation (standard deviation) is 7.229, while the total score (sum) is 3441.
To determine the average level of achievement of respondents on interest in learning, the following formula is used:

Level of achievement
x 100% =82,32% From the data the level of achievement of the creativity score of 82.32% is included in the high category.

Interest in Learning
From the research interest in learning data, the lowest (minimum) score of 84 and the highest (maximum) 104, the average (mean) 90.34, the middle score (median) 95.00, the most frequent score (mode) 92, and The standard deviation (standard deviation) is 4.289, while the total score (sum) is 3623.
To determine the average level of achievement of the respondents' interest in learning, the following formula is used: From the data on the level of achievement of the interest score learning by 82.90% included in the high category.

Learning Achievement
From the results of the assessment obtained the value of learning achievement obtained the lowest score of 60 and the highest value of 90 based on the distribution of these values obtained an average (mean) = 75.53, middle score (median) = 75, the most frequent score (mode) = 75, and standard deviation (standard deviation) = 7,780 and while the total score (sum) is 2870.
To determine the average level of achievement of respondents on learning achievement, the following formula is used: Level of achievement = x 100% = 75,52 % Based on the resultsobtained the level of achievement of respondents learning achievement of 75.52% included in the medium category.

Prerequisite Test Results Analysis a. of the Normality
Test The normality test used is the Lilliefors by looking at the value on the Kolmogorov-Smirnov. Based on table 21, it is known that the tolerance value of the creativity variable (X1) and interest in learning (X2) is 0.982 > 0.10 and the Variance Inflation Factor (VIF) value for the two independent variables, namely creativity and interest in learning is 1.018. Because the VIF value is less than 5, it can be concluded that the regression model does not find any multicollinearity problems.

Hypothesis Testing
To test Hypothesis 1 and hypothesis 2 were tested by simple linear regression test with -t test, while hypothesis 3 used multiple linear regression test with F test.  (1,690), or significant < alpha (0.021 < 0.05) then Ho is rejected and Ha is accepted, meaning that there is a significant influence between creativity (X1) on student learning achievement (Y) Percentage of creativity (X1) on student learning achievement (Y) by 14%, Munandar (2009: 19) suggests that "creativity is the ability to make new combinations based on previously existing materials, information and data to be meaningful and useful". 2. The second hypothesis is obtained t arithmetic = 5.085 and t table 1.690 (attachment 19), with df = nk-1 = 38-2-1 = 35 (k = number of independent variables). So it can be said that t count (5.085) > t table (1.690) or significant < alpha (0.000 < 0.05) then Ho is rejected and Ha is accepted, meaning that there is a significant influence between learning interest (X2) on learning achievement (Y). The percentage of the influence of interest in learning on learning achievement is 41.8%, Slameto (2010: 180) suggests "Interest is a sense of preference and a sense of attachment to a thing or activity, without anyone telling". 3. The third hypothesis This hypothesis was tested using the significance test of multiple linear regression with the F test (simultaneous). Obtained R2 (R square) of 0.503. Then the magnitude of the influence of creativity and interest in learning on learning achievement is 0.503 x 100% = 50.3%. This shows the magnitude of the influence of creativity (X1) and interest in learning (X2) together on learning outcomes is 50.3%.
