Closed Beta Testing on e-Label Batik Application to Know the Best Environment for Optimal Application Performance

The Batik of Pekalongan is a heritage that continues to be maintained and until now it is still used as a source of livelihood for the majority of the people in Pekalongan city, so the city of Pekalongan is known as the city of batik. However, the existence of batik is facing a serious threat, caused by the abundance of textile products with batik motifs (batik printing) on the market, but not matched by increased public knowledge of batik. Various efforts, both in Pekalongan city government through the labeling of batik, and ASEPHI in Pekalongan city through the implementation of original batik hologram, has been done to maintain the sustainability of batik. But this has not yet provided optimal results, because it is still found that the fraudulent batik seller who put the original batik label/hologram on batik printing, thus harming the society, harming batik craftsmen/producers and tarnish the batik image of Pekalongan city. This happened because the batik label or the original batik hologram had not been connected to a computer-based information system, so that they cannot monitor and validate the attachment of original batik labels/holograms. For this reason, researchers developed a e-label batik application that was able to be used by the community to scan batik labels that produced by the e-label batik application, so that can know information the authenticity of the batik. The application is also equipped with facilities that provide convenience to monitor, validate, get feedback from the community and become a learning media for the community towards batik. The development of e-label batik applications has gone through the stages of alpha testing and continued with closed beta testing to find out the ideal environment, So that the performance of the batik e label application is optimal, and can be used properly by the community.

Introduction
Batik Pekalongan city is a legacy that continues to be preserved and used as a source of livelihood for the majority of the people in Pekalongan city, so that the city of Pekalongan is known as the city of batik and batik is a typical product of Pekalongan city.However, today the existence of batik is facing severe challenges, caused by the abundance of textile products with batik motifs (batik printing) on the market but it is not balanced with the increasing knowledge of the people about batik, so that it has an impact on: 1. the emergence of misperceptions of the people who consider textile products with batik motifs (batik printing) are batik, so that it provides an opportunity for individuals who sell batik to seek profits by cheating, by offering products that are sold are batik.Actually textile products with batik motifs not only harm the people who buy the product, but also batik craftsmen / producers and at the same time tarnish the batik image of Pekalongan city [1] [2]. 2. Cheaper selling prices owned by textile products with batik motifs, thus encouraging people to prefer to buy batik-based textile products compared to original batik and this becomes one factor in the decline in sales turnover Pekalongan batik city and threatens the sustainability of Pekalongan city batik craftsmen / producers.
Based on this, several stakeholders have tried to overcome it through the following methods: 1.The Pekalongan city government has issued Peraturan Daerah Nomor 6 Tahun 2014 about the use of Pekalongan batik labels, as a protective effort for the batik of Pekalongan city, batik craftsmen / producers of Pekalongan city and people who buy batik in / from Pekalongan city [3].
2. Asosiasi Eksportir dan Produsen Handicraft Indonesia (ASEPHI) Pekalongan City which accommodates the batik producers of Pekalongan City, has announced the use of original batik hologram on April 12, 2016, as an effort to provide a marker for the community that the product they buy is authentic batik, not textile products with batik motifs.this makes people not easily deceived by unscrupulous batik sellers.
However, these efforts have not provided optimal results, because there are still people who sell batik that put the original batik label/hologram not on the designation.For example, label/hologram batik tulis is affixed to batik cap, thus harming the people who bought it.This can happen because original batik labels and holograms have not been connected to computer-based information system, so that they cannot monitor and validate the attachment of original batik labels/holograms.
To overcome it, researchers developed a e-label batik application that could be used by the community to scan the batik label so that information on the authenticity of the batik can be known.The application is equipped with facilities that make it easier for relevant stakeholders to monitor, validate, get feedback from the community and become a community learning media for batik.The e-label batik application developed by researchers is an augmented reality based application that can be accessed from various devices and operating system so that it will make it easier for users.To utilize the application, users can directly access it through the available site address.The following is the technical specification of the e-label batik application (table 1):

Community
His authority is to be able to scan batik labels that attached on batik product to get information on the authenticity of batik, can learn various information about batik and can submit complaints/criticisms /suggestions and get a reply.
For batik craftsmen/producers, can use the application after registering membership to the application and validated by the manager/administrator.For community user there is no need to register.The following is the appearance of the e-label batik application (table 2): Table 2.

General description of e-label batik application
The e-label batik application has gone through the stages of alpha testing conducted by researchers and the test results show that the application has good performance for the clarity and speed of information displayed when the batik label is scanned with a smartphone camera.The next stage of testing is to do a closed beta test, by inviting 10 users (not the research team) who will be asked to scan the batik label that has been provided with hardware, software and test cases that have been determined.

Material and Methods
The following are the preparation stage for testing the closed beta application of the e-label batik, that is: 1. Setting up the application The e-label batik application has been uploaded to hosting, so it can be accessed easily by users.

Prepare test cases
The following is a test case (table 3) to test the clarity and the speed of information is displayed:

Results and Discussion
To facilitate the analysis, the results of the tests are divided into 6 groups of 28 existing test cases (14 kasus uji kecepatan dan 14 kasus uji kejelasan), that is: 1. Speed testing using Mozilla or Google Chrome, scan position perpendicular to 90 0 , the user is free to choose the camera resolution het provided and the scan distance is 5 cm or 10 cm. 2. Clarity testing using Mozilla or Google Chrome, scan position perpendicular to 90 0 , the user is free to choose the camera resolution het provided and the scan distance is 5 cm or 10 cm. 3. Speed testing using Mozilla or Google Chrome, position scan tilt 45 0 or 70 0 , the user is free to choose very fast, so that if the three values are summed up, the following results are obtained: The value of the test case with Mozilla and the scan distance of 5 cm is 50.56 The value of the test case with Google Chrome and the scan distance of 5 cm is 52.78 The value of the test case with Mozilla and the scan distance of 10 cm is 48.33 The value of the test case with Google Chrome and the scan distance of 10 cm is 48.89Of the four values above, the test cases that have values above 50 are only those with a scan distance of 5 cm, scanned perpendicular to 90 0 , using Mozilla and Google Chrome and camera resolution between 5 mp or 8 mp or 13 mp.
2. Group 2 results as shown in Figure 3   The category of clarity of information that can still be read well by users is the category of quite fast, fast and very fast, so that if the three values are summed up, the following results are obtained: The The category of the speed of the appearance of information that does not interfere with the user is quite fast, fast and All test case results have values above 50, so the scan distance, scan position perpendicular to 90 0 , web browser and camera resolution do not affect application performance in displaying information that can be read well by the user.
3. Group 3 results as shown in Figure 4 below:  The category of the speed of the appearance of information that does not interfere with the user is quite fast, fast and very fast, so that if the three values are summed up, the following results are obtained: The value of the test case with Mozilla and scan slope 70 0 is 37.22 Of the four values above, the test case has a value above 50, only in the test case with a 45 0 scan, scan distance 15 cm, using Mozilla and Google Chrome, and camera resolution between 5 mp or 8 mp or 13 mp.
5. Group 5 results as shown in Figure 6  The category of the speed of the appearance of information that does not interfere with the user is quite fast, fast and very fast, so that if the three values are summed up, the following results are obtained: The value of the test case with Mozilla and camera resolution 13 mp is 92.78 10,00 30,00 The value of the test case with Mozilla and and camera The category of clarity of information that can still be read well by users is the category of quite fast, fast and very fast, so that if the three values are summed up, the following results are obtained: The The value of the test case with Google Chrome and camera resolution 5 mp is 7.22 Of the six values above, there are only 4 test cases that have values above 50, a test case that uses a camera resolution of 13 mp and 8 mp, using Mozilla and Google Chrome, scan distance 15 cm and scanned perpendicular to 90 0 .
If the scan position is tilted, it should be taken from a slope of 45 0 with distance 15 cm, with Mozilla or Google Chrome web browsers and camera resolution for scanning is 5 mp or 8 mp or 13 mp.

Conclusion
1.So that the performance of the e-label batik application is optimal in terms of speed display information and clarity of the information displayed, then the ideal environment is: The scan position is perpendicular to 90 0 by choice 5 cm or 15 cm distance, with Mozilla or Google Chrome web browsers dan camera resolution for scanning is 8 mp or 13 mp.The scan position is tilted from a slope of 45 0 with distance 15 cm with Google Chrome and camera resolution for scanning is 5 mp or 8 mp or 13 mp
