Abstract

Today, social media has become a new lifestyle for modern society. One of the most popular social media is Twitter. The character limitation when tweeting on Twitter makes the message conveyed by its users short, solid and clear. Thus, the complaints of users as outlined in a tweet can be analyzed using text classification which can then be used as a new method to determine the stress level of a person. In which up to this time, to determine the stress level is still done manually using a questionnaire system. The text classification used in this study is the Improved k-Nearest Neighbor method which is an improvisation of the k-Nearest Neighbor method which has a weakness in the use of k values for all classes. In addition, to improve the accuracy of the system and eliminate less relevant features, chi-square feature selection is used which can eliminate less relevant features without reducing the accuracy of the system. From 5 feature ratio tests, the best value is obtained at the feature ratio of 25% and k-value = 20 with an average precision value of 70%, the average recall is 67.2%, the average accuracy is 83.3%, and the average f-measure is 66.3%. From this research, it can be concluded that feature selection can increase the average precision, recall, accuracy, and f-measure.

Abstract

One of human welfare is derived from the value of health. For health, it is obtained by maintaining food intake for the body. Maintaining food intake can be done in consultation with experts or the application of a balanced diet. Universitas Brawijaya Malang Clinic is one of the nutrition health service providers. The clinic conducts services based on the Hospital Nutrition Guidelines book in 2011. The services carried out are in the form of recording personal data until monitoring and evaluation. Recording patient data currently using conventional methods, causing limited access to patient data services. In making a diet menu design the patient needs food data and does not exceed the patient intervention limit. This study aims to develop an information system that assists nutritionists in serving the nutritional health of patients using the waterfall development method. The technology used to develop the system is the use of laravel frameworks with the website programming language. In making system requirements engineering, 30 functional requirements were obtained which were then made designs and then implemented. In the final stage of the study, testing was carried out using the black box and white box method. The results of the black box testing of 30 functional requirements found 52 test cases that gave a valid status of 100% which meant that it was in accordance with the design made.

Abstract

Unit testing is one phase in the software testing process, but there are still some programmers who are reluctant to do the unit testing. These problems also occur in PT. Global Digital Niaga. Some programmers don't pay attention to the quality of the unit testing's code and only pay attention to the value of the unit testing code coverage. Researchers develop applications that can be used to scan unit testing codes and identify the incorrect unit testing code based on rules. The scanning process starts with searching for information on the uploaded project. Then, application scans production code and unit testing code using JavaParser library. After that, the application analyzes each scanned unit test code whether the code matches with writing rules or not. Then, the application saves the scan results and displays them. The first phase of this research is the study of literature. Then, the requirements engineering produced 25 functional and 2 non-functional. Next is the design and followed by the implementation by creating a website application. After that, the testing with a 100% pass, 100% valid, and 100% accurate for unit, validation, and accuracy testing. The application can run on eight different browsers for compatibility testing.

Abstract

Test case prioritization is a strategy of regression testing. It can reduce the cost of regression testing. Test case prioritization based on lexicographical ordering is considered to be the best technique based on its Average Percentage Fault Detection (APFD). This technique determines test case prioritization based on coverage information of each test case. There have been no studies that implement this technique into a system and research shows that prioritizing test cases based on code coverage is expensive both in terms of time and resources. Because the more number of test cases, the greater size of the code coverage information that have to be read. Therefore, this study developed an application system for test case prioritization based on lexicographical ordering. This system aims to help the process of reading coverage information and determining test case prioritization automatically. So this system is expected to accelerate the determination of test case prioritization. The results of testing phase show that the system has 100% accuracy with reading coverage information in each test case also finding prioritization in less than 8 seconds. This paper will summarize the application system development process. The stages described from the introduction, research methodology, results and discussion, and getting conclusions from the research.

Abstract

Code Smell is a structural pattern part of a software program code that has a bad design. The code structure pattern that contributes to excessive coupling is code smell feature envy. Feature Envy occurs because of the high coupling of the inaccuracy of class member placement within a class. Incorrect class member placement will affect the program code structure if a change is made. However, the different patterns of perceptions of each programmer resulted in the difficulty of measuring the code smell feature envy. This study aims to equate the perceptions of programmers by building an application system that can detect the envy smell feature code automatically so that it can simplify the implementation of clean code smell feature envy. The application system for detecting the smell feature envy code was developed based on feature envy factor as a reference in measuring and calculating its value. This system has been tested using the White box method for unit testing and integration testing and then the Black Box method for validation testing with pass status or valid for each method that has been applied. This system also gets 100% accuracy rate for each project tested.

Abstract

A good quality software is usually understood as a lack of errors within the software. The previous study entitled “Towards a Reliable Identification of Deficient Code with a Combination of Software Metrics” has been done by Beranic in 2018 and showed the use of combination of 8 object-oriented software metrics to identify deficient code in certain software. The deficient code detection can be used to calculate the quality rate. However, the calculation of deficient code and quality rate are done separately. To overcome this problem, a tool is made for the calculation of quality rate with a combination of software metrics. This tool was built using Software Development Life Cycle (SDLC) Waterfall method and coded in Java. This tool runs on a desktop platform and use Java project as its input. Requirement engineering process in this tool produced 3 functional requirements and 1 non-functional requirement. The design is in object-oriented and produced 1 class diagram, 3 sequence diagrams, 5 algorithms, and 3 user interface design. The design is develop using JavaFX and ASTParser library. The outcome of the white-box and black-box tests indicate that this tool has a validation percentage of 100%.

Abstract

The educational institutions cannot be separated from scheduling activities because it helps the learning activities to be run properly. However, there are times when scheduling can cause problems such as the clash of the teaching schedule of a lecturer that happened in the Mechanical Engineering Department of Politeknik Negeri Malang (JTM POLINEMA). The manually-done scheduling process by each JTM POLINEMA's Head of the Study Program (KPS) is the reason that the learning activities have to be delayed up to one week. Therefore, this study aims to assist the work of KPS in arranging lecturers' schedules by designing and developing a web-based scheduling system that helps minimize human errors in scheduling and facilitating the schedules' distribution for each lecturer. The development of this system consists of requirement analysis, design, implementation, and system testing. This application system is designed using an object-oriented (OOP) approach and waterfall software development model and will be implemented using the PHP programming language. For testing, this system will be tested with whitebox testing, blackbox testing, and compatibility testing. The results of this study are 100% valid in unit testing, 97.5% valid in validation testing, and the system can work properly on Mozilla Firefox and Google Chrome.

Abstract

Custom clothing manufacturing is one of the bustling businesses with the growth of SMEs production of apparel reaching 7.05 percent in 2018 based on data from the Central Statistics Agency. Through current technological developments, the use of technology for economics can provide benefits for SMEs such as custom clothing manufacturing. However, the application of e-marketplace that already exists in Indonesia do not provide adequate functions for the process of ordering custom clothing. Therefore, ordering custom clothing service cannot be made through an existing e-marketplace application. The problem that occurs in the conventional process is that customers are having trouble finding appropriate prices from various custom clothing merchants, customers have trouble monitoring the progress of the order and the processing period is not clear. Based on these problems, developing e-marketplace applications for custom clothing manufacturing is expected to solve these problems. The first process of the research is requirements analysis and obtained 28 functionals and 2 non-functionals functions, namely compatibility and performance. Then the system design process and system implementation process are carried out that refers to the acquisition of the requirement analysis process. The application implementation uses PHP based Laravel framework. Unit and integration level test results, as well as validation testing of the application, are 100 percent valid. The compatibility test results show that the application has no compatibility issues and can run on multiple platforms. The performance test results show that the application has an average performance that is the application can be accessed within a period of 1 to 2.5 seconds.
