Introduction
Currently, the development of learning strategies at the basic, intermediate, and high level has undergone changes in line with advances in information technology. Advancement of information technology has penetrated to various sides of society's life, including also in the field of education. That matter reinforced by the statement of Raja and Nagasubramani [1] in 2018 which states that technology has transformed and revolutionized the field of education through the use of information technology in automating the learning process so that the transfer of knowledge becomes faster and easier.
Some examples of information technology-based learning strategies that can be used in the learning process both at the elementary school level up to college whether implemented in the classroom or outside the class include e-learning, e-teaching, blended learning, and others. In particular, one of the technology-based learning strategies that are currently being used in college is blended learning. The reason for the use of blended learning because the quality of learning can still be maintained through the learning process, which is a combination of face-to-face learning in the classroom with information technology-assisted learning. It needs the right platform following the learning objectives and most importantly is easy to use to be able to operate blended learning in college optimally. Some platforms that are familiar and often used to support the implementation of blended learning in college are Edmodo and Moodle.
However, the fact that occurs especially when researchers directly were involved in the learning process with learning strategies used blended learning that utilized of Moodle platform in Assessment and Evaluation course in the Department of Information Technology Education, Universitas Pendidikan Ganesha. Which it shows that not all blended learning that is supported by the Moodle platform can running well and stable, but there are also found its weakness.
The weakness was known when there was a complaint from students that revealed that access to blended learning with Moodle for Assessment and Evaluation course was slow. The weaknesses of Moodle related with slow access, reinforced by the research results in 2018 that was conducted by Ndlovu and Mostert [2] which revealed that: "One of the obstacles from Moodle was the speed of access was slow". Other research results which in essence also indicate the weakness of Moodle that is research conducted by Ivanović et al. [3] in 2009 stated that gaps that often appear in the learning process using Moodle are slow loading when accessed by many users.
Besides used blended learning that utilized the Moodle platform, the researcher has also used Edmodo platform to support the learning process of Assessment and Evaluation course. However, there was also a weakness that appears on the Edmodo platform that was used to support blended learning in the Assessment and Evaluation course was the use of full English on Edmodo platform that causes difficulties in the operation of blended learning for students and lecturers who wasn't understanding about English. The weakness that was found from Edmodo platform was also reinforced by research conducted in 2017 by Gay and Sofyan [4] which in principle states that "the use of language in Edmodo program that is still in English so that sometimes make it difficult for the lecturers and students who have limited knowledge of English".
From some of the problem findings and reinforced by some of the research results that have described previous, then it is necessary to do this research. Besides, based there were the findings of several problems in the utilization of Moodle and Edmodo platforms was in support of the blended learning implementation in universities, it needs to search the innovation to overcome them. The innovation intended is the utilization of Kelase platform in supporting the implementation of blended learning in universities.
Based on the findings of problems and the innovation as its solutions, then the problem statement in this research was: "How did the implementation of blended learning with Kelase platform in supporting the learning process of Assessment and Evaluation course?" From that problem statement, it is clear that the purpose of this research is to know the implementation of blended learning with Kelase platform used in a learning process, especially in the Assessment and Evaluation course at the Department of Information Technology Education, Universitas Pendidikan Ganesha.
Some research results related to this research include: research that was conducted in 2016 by Al-Ajlan and Hammoudeh [5], where the results of their research had similarities with this research in terms of its research focus was about implementation a system/platform that supports learning strategies in universities. The difference lies in the platform was used and the form of its learning strategy, wherein their research more focused on the Moodle platform to support the implementation of e-learning, while in this research more focus on Kelase platform to support the implementation of blended learning.
The research of Lin, Tseng, and Chiang in 2017 [6], generally had similarities with this research in terms of its research focus that was about implementation an interactive media in the form of blended learning that could be used to encourage the improvement of education quality in universities. The difference lies in the platform was used to create blended learning, and the courses were packed with blended learning. Where in the research that had been done by Lin, Tseng, and Chiang focus more on the Moodle platform in made the blended learning that was used to support the learning process of Mathematics courses. While in this research, more focus on Kelase platform in made blended learning, which was used to support the learning process of Assessment and Evaluation course.
The research that had been carried out by Wichadee in 2017 [7] had similarities with this research that was in terms of its research focus about the implementation of a platform that supports a form of learning strategy so that it could optimize the process of learning. The difference was on the platform that was used, the form of learning strategies that were used in the learning process, and the location of its implementation. Where, in research conducted by Wichadee focus more on the utilization of Edmodo platform to made e-learning which was implemented in vocational high school, while in this research more focus on utilization of Kelase platform to made blended learning which was implemented in college.
The research that was conducted in 2017 by Patmanthara and Hidayat [8] had similarities with this research in terms of its research focus in the implementation a system/platform used to create blended learning in supporting the learning process. The difference lies in the platform used in making blended learning and the location of the implementation of blended learning. Research conducted by Patmanthara and Hidayat more focus on utilization of Edmodo platform to made blended learning and location of its implementation in vocational high school, while in this research more focus on Kelase platform utilization to made blended learning and its implementation location focused on college.

Literature Review

Blended learning
Based on research that was conducted by Lalima and Dangwal in 2017 [9], it was stated that "blended learning is an innovative concept that seeks to combine offline learning in the classroom with online learning through ICT support that can be done outside the classroom". That statement reinforced with the Shivam and Singh's research in 2015 [10] which states that "blended learning is a combination that occurs between traditional learning carried out face-to-face with online learning conducted via the internet".
According to some definitions above, it can be generated the general conclusion that blended learning is a learning strategy which combines between conventional learning and information technology-based learning, in which learning process can be conducted effectively and with good interaction quality between the lecturers and the students.

Kelase
Kelase is private social networks at the same time online learning environment for institutions education and organization. Kelase developed by PT. Edukasi 101 (one of the private companies in Indonesia with business scope in the field of education) to improve the quality of education and training as well as the productivity of the organization in Indonesia [11]. Kelase's service allows educators to create online classes for their students, so if the educator had not been physically present in the classroom, he could teach from anywhere as long as he had an internet connection [12]. The features available on Kelase, such as • Social features which are used to share status messages, links and photos/images on your page, institutions/organizations, and classes, provide comments, like and function friendship • Collaboration features used for making activities together on a private page and community and also conduct discussions • Features of information and communication used to receive news and comment on the page of news from agencies/organizations, as well as send and receive private messages • Learning function which is used to create and follow the online classroom learning with various learning activities, such as the reading/blog, tasks, quiz, and discussion forum [11].
From those explanations, it can be concluded that Kelase is one platform with a similar shape as a social network developed by an organization called PT. Edukasi 101 from Indonesia, where it can be used to create online classes for several levels of education ranging from elementary to university that is not paid/free equipped with several features, including social features; collaboration features; features of information and communication; and learning function. The language of instruction used in each feature on the Kelase platform is mostly Indonesian.

Assessment
According to Fuentealba [13], Assessment is a tool used to determine the level of learning that has been achieved by students with standard reference and curricular objectives. Wiliam [14] states that only through the assessment process, we can know the success of learning activities. Based on several statements about those assessment, can get a general conclusion that the assessment is an activity conducted to interpret data measurement results of students' ability in following the learning process.

Evaluation
According to Aziz, Mahmood, and Rehman [15], "evaluation is an activity carried out to determine the quality and effectiveness of education to fit the expected objectives". Marlina, Putri, and Darmawijoyo [16] stated that evaluation is a stage to see the effectiveness of a program, whether it has been running following the initial expectations had set or not following initial expectations.
Based on several explanations related to the definition of evaluation mentioned above, a general conclusion can be get that evaluation is an activity carried out by evaluators in a comprehensive and structured in collecting, processing, analyzing, and presenting data into valuable information in order to facilitate policy makers in making a decision whether a program is still running or not.

Discussion
Based on the research results described above, it could be said that there were 40 personnel selected and involved in the introduction and training of the use of blended learning with Kelase platform. After the introduction and operation of the use of blended learning with Kelase platform, the next was conducted the system testing. The test result of the system was obtained through the response from 40 users to blended learning with Kelase platform, where the users' response result showed the percentage average was 90.2% so that generally the implementation of blended learning with Kelase platform was very good if was reviewed based on the categorization of effectiveness rate that refers to scale's five.
The results of this research have been able to provide solution/answer related to problems about slow access when using Moodle platform found in previous research that was conducted by Ndlovu and Mostert in 2018 [2], and research that was conducted by Ivanović et al. in 2009 [3]. The results of this research had answered the problems found in those two previous kinds of research, which was shown with the percentage obtained on item-4 about the access speed when using Kelase platform was 95.5% so including to very good category.
The results of this research were also able to provide a solution to the problems found in research that was conducted by Gay and Sofyan in 2017 [4] related to the constrained in blended learning that used full English in Edmodo platform for users who had weaknesses in English. The result of this research was the solution/answer to that problem. It was indicated from the percentage obtained on the item number-8 about the language was used in blended learning operation with Kelase platform was 92.0%, so it was also very good categorized.
Although the results of this research had been able to provide solutions/answers for some constraints found in other researches, in this research also was found the obstacles in the material content was presented in the blended learning that wasn't depth. It was shown in the percentage obtained on item-5 about the completeness and depth of the material content of Assessment and Evaluation course that was presented in blended learning with Kelase platform was 76.5% so that it was categorized as sufficient.

Conclusion
Generally, the implementation of blended learning with Kelase platform was very good implemented to support the learning process of Assessment and Evaluation course. This platform is very easy and fast to access, easy to be understood by users who have limitations in English, and equipped with full features needed in the process learning, such as: features to facilitate the user in uploading and downloading the learning material, features to facilitate the lecturer in uploading the tests/quiz on each chapter of the learning material, features to facilitate the student to answer the tests/quiz and see the assessment result of the tests/quiz that had been answered, features to facilitate the interaction or communication between lecturers and students, and also features to facilitate the communication between students who follow the group/class. The recommendations given to overcome the obstacles in this research were related to the lack of depth in the material content it is by searching the Assessment and Evaluation materials from various sources either from books or journals related to Assessment and Evaluation so that the material can be more extensive and deep.
