Abstract

The procurement of beauty competitions from ornamental betta fish has been held throughout Indonesia. The concept of judging and assessment carried out in the ornamental betta fish beauty competition still uses manual bookkeeping. The assessment with the national scale (SNI) is still a concern for the competition participants because of the lack of knowledge about the standard for judging ornamental betta fish contests. DSS (Decision Support System) can be an application development solution to determine the candidate for the winner of the ornamental betta fish contest. The criteria used include color value, neatness value, proportion value, mental value, and appearance value. The calculation method used in conducting this research is AHP and TOPSIS methods. The recommendations made will go through the AHP process for weighting based on the SNI assessment standard, while TOPSIS is used to receive alternatives from users. Then the ranking is based on the preference value generated by the TOPSIS method. This study has obtained the results of the application of the AHP and TOPSIS methods to make a recommendation system for contestants for winning ornamental betta fish correctly. Testing the level of user satisfaction obtains satisfaction results measured through the EUCS (End User Computing Satisfaction) dimension with the help of a Likert Scale calculation, so that it gets a satisfaction value of 87.89%

Abstract

Most Software Development Processes (SDP) project failures occur due to errors in estimating cost, time, and effort during the planning phase. This happened because the planning carried out still relied on the intuition and experience of the programmer. One approach that can be taken to plan the right SDP is to know the value of SDP productivity. The focus of this research is to determine the value of productivity based on the differences in programmers’ skills. The case study is conducted to determine the productivity value of the web-based software that has been built, namely McDelivery. The productivity value is calculated based on the ratio of software size to the effort. Software size is obtained through the calculation of the Application Function Point Count (APFC). Meanwhile, the effort is obtained through expert judgment to determine the time needed by the development team at the junior, middle, and senior software developers to implement software functionality in person-day to the form of program code. The result shows that the productivity value of SDP is directly proportional to the level of ability of the programmers. These productivity values ​​can be used as a solution option to calculate the estimated time, cost, and even the availability of programmers that are adjusted to the conditions faced in planning software development

Abstract

The Javanese script, known as Hanacaraka, or Carakan, is one of the traditional Indonesian scripts developed and used on the island of Java. The government's efforts to preserve the use of Javanese language and script by making Javanese a compulsory subject of local content at the education level in Central Java and East Java. In the basic competence of writing, the Javanese script has a complicated shape so that students have difficulty writing and recognizing Javanese script writing. Through this research a web-based basic Javanese writing learning application was designed that can recognize handwriting digitally which aims to help learn basic hanacaraka writing for beginners, especially students at the basic education level in Central Java and East Java. Handwriting Recognition is a system that can recognize handwritten characters and convert them into text that can be read and understood by machines or computers. The handwriting recognition process in this study uses the Convolutional Neural Network (CNN) algorithm which has the capability and ability to recognize patterns in images. Based on the tests that have been carried out between the two architectural models that have been made, the performance of the CNN model that will be used from various experiments has an accuracy of 98.29% and a loss of 0.0746 on the training data. As well as producing an average accuracy value of 99.52%, an average error rate of 0.48%, an overall accuracy of 95.03% and an overall error rate of 4.97%.

Abstract

Automation testing is much more efficient and accurate, the script is easy to document, and update compared to manual testing. Testing a website may necessitate time and effort to learn the tools to be used. Cucumber and Robot Framework are well-known open-source frameworks, according to Stack Overflow and GitHub. Cucumber and Robot Framework are known on an international scale, especially Robot Framework, which is often used by large companies. Each uses the Java and Python languages, which both support BDD. The comparative efforts of the two tools aim to help testers compare and determine automated testing tools in the BisOps Logee Port Web Admin case study based on the effectiveness and efficiency of the tools and create specific test cases as test documentation so that testers do not need to spend time analyzing both. Because this research involves evaluation and comparison, several criteria were chosen to support the evaluation process, namely functionality, reliability, usability, performance efficiency, and portability. The results of this study show that both tools can be recommended for novice QA's who want to learn the basics of automation by implementing BDD. Meanwhile, for QA's who have done automation before and want to do more in-depth configuration and reporting, it is recommended to use Robot Framework because the syntax is short, has lots of keywords that make it easier for testers, and can make the testing system shorter but more specific.
