Software modeling is an integral practice for software engineers, especially as the complexity of software solutions increases. Unified Modeling Language (UML) is the industry standard for software modeling. however, it is often used incorrectly and misunderstood by novice software designers. This study is centered around understanding patterns of student proficiency of abstraction and systems thinking within a software modeling context. The participants of this study (n = 97) belonged to a systems analysis and design course that is primarily taken by second-year university students. The exam solutions to a case study from the course were evaluated for modeling proficiency. As evidence of proficiency in abstract thinking and systems thinking, we evaluated UML activity diagrams, class diagrams, and sequence diagrams and the alignment between these representations in terms of functions, structures, and behaviors. The results suggest students being proficient in modeling the functional aspects of an information system while facing some difficulty in capturing the structural and behavioral aspects of an information system. Clustering analysis revealed two groups within the sample, with one group displaying a significantly higher abstraction and systems thinking ability. Statistically significant correlations were also found between student proficiency of abstraction and their modeling proficiency in terms of functions, structures, and behaviors.

Companies need an information system that supports and can provide fast and accurate data. This research was conducted as an effort to improve the existing payroll system so that it is more effective and efficient. At this time several companies engaged in the payroll system services are still at their maximum, starting from recording attendance to payroll, making it possible when the process takes place there are errors in payroll, inaccurate reports made and late in searching for the required data. The research information system uses object-oriented Unified Modeling Language (UML) software modeling. Researchers use Unified Modeling Language modeling with the aim that the desired system can be provided properly so that problems in the existing system are resolved. This uml modeling process begins with analyzing the system's needs and implementing it in usecase traffic diagrams by making class diagrams, sequence diagrams, and activity diagrams. UML software modeling also provides benefits in software development and is able to monitor the flow or system flow expected by the company. This research also uses the approach waterfall method, namely analysis, design, code generation program, testing and maintenance in designing. This information system design is the best solution to solve problems that exist in the payroll system. The payroll system that utilizes software to support the process provides a very effective contribution to the company and the development process will still be carried out for existing problems.

Yoga Farm is a Micro, Small, and Medium Enterprises (MSME) that focuses on catfish breeding that is still doing business processes manually. With this process, information received by related parties is very difficult to obtain quickly. Therefore, the product is still not widely known, and customers are still few because the system used in sales and promotions still uses a manual system. The research method used is qualitative. This study aims to create a sales information system recommended at Yoga Farm and design using Unified modeling language (UML) for the recommended business processes. Customers will get product information in real-time, products can be widely recognized, and the number of Yoga Farm customers can increase. Based on the results of this study, adoption of a web-based sales information system can certainly make it easier to get the latest information quickly, can expand the market and can also facilitate customers in the transaction. For future research, this research can be used as a reference for conducting similar studies at other MSMEs to increase sales

In the research space of interactive surface environments, toolkits have a central role in rapid prototyping. They simplify operating both hardware and software technologies. However, the accelerated development of these technologies discontinues the usability of toolkits, in some cases making toolkits obsolete. One approach to address this challenge is establishing future-proof hardware and software interfaces based on the study of prevailing interactive surface environments. In this paper, we study interactive surface implementations and proposes a metamodeling infrastructure to support the analysis of prevailing implementations toward designing future-proof hardware and software modeling constructs. Our approach employs the unified modeling language and emphasizes the flexible description of existing systems. To evaluate the proposed approach, six existing research prototypes have been used to conduct traces, and the consistency demonstrated is promising. A face validation study with experts has also been conducted. Expert perceptions from the face validation study suggest potential benefit in using the UML-based approach as a shared notation for studying interactive surface environments.

During the object-oriented software design phase, the designers have to describe the dynamic aspect of the system under development through the most common interaction diagram variant in UML 2.0, i.e. sequence diagrams. Some novice designers, including undergraduate and postgraduate students, suffer from making inappropriate models due to insufficiently detailed guidance required to develop such sequence diagrams. This paper classifies some potential mistakes which are likely performed by such novice designers, and discusses the corresponding corrections. We summarized such mistakes based on our long experiences in teaching software modeling classes as well as software analysis and design classes. There were classified twenty-one potential mistakes with respect to the syntactical and semantical correctness of the developed models. It is concluded that novice designers have to be aware and take into account the identified mistakes in such a way they can produce correct sequence diagrams.
