“…Database design is one of the illstructured problems in this problem typology (Connolly & Begg, 2006). Therefore, learning the database design process is also a difficult process (Connolly & Begg, 2006;Rashkovits & Lavy, 2021).…”

“…The student must understand the relationship among these four steps for database design to be carried out healthily. Otherwise, many errors may appear in the early stages of the design process (see also Rashkovits & Lavy, 2021). Giving these four stages followed in the database design process together in the teaching process may allow the student to see different stages of the design simultaneously, thus creating a healthier problem scheme and making a more successful database design.…”

In this study, the effect of multiple representation method and prior knowledge level in solving ill-structured problems was investigated. Quasi-experimental and 2x2 (multiple representation method x prior knowledge level) factorial designs were used in the study. The study group consists of 39 undergraduate students. The dependent variables of the study were determined as problem solving skills, cognitive load, and permanence. The independent variables were considered as multiple representation method (step-by-step, holistic) and prior knowledge levels (novice, expert). Prior knowledge level test, problem solving skills test and cognitive load scale developed to measure the variables were used as data collection tools within the scope of the study. The data was analysed with two-way analysis of variance and independent groups t-test as the data obtained from the data collection tools exhibited normal distribution. In the results that were significant in the analysis, Cohen (d) in the independent groups t-tests and eta-square (η2) in the two-way analysis of variance were also shown. As a result of the research, it is evident that the level of prior knowledge and the interaction (interaction effect) of the level of prior knowledge and the multiple representation method affect problem solving skills. In addition, it was concluded that the interaction of multiple representation method and prior knowledge level was statistically significant in terms of cognitive load variable. The findings supported the expertise reversal effect.

“…ERD merupakan model visual yang banyak digunakan untuk menggambarkan entitas bisnis, atributnya, dan hubungannya satu sama lain (Gupta et al, 2021). Perancangan ERD dari sistem informasi pembayaran uang sekolah ini terdapat entitas, relasi, atribut, atribut kunci primer dan asosiasi (Rashkovits & Lavy, 2021).

The Tuition Payment Information System was designed because at this time the payment of tuition at SMP Islam Cilacap still uses the general ledger, causing inaccuracies in payment data by employees (administrative). The purpose of this research is to help solve problems in the processing of tuition payment data, making payment data reports, searching payment data, knowing payment data information, and knowing the school money payment report. The system is designed using MVC (Model-View-Controller) architecture and SMS Gateway notifications as well as system development methods using System Development Life Cycle (SDLC) with Waterfall model. In addition, the system design uses PHP and HTML programming languages, database management is MySQL and uses the Laravel framework. Based on the results of the system test and the results of the questionnaire by 10 respondents that 14% stated enough, 44% stated well and 42% stated very well calculated by the calculation of the Likert scale of 86% entered the excellent qualification which means successful. So it can be concluded that this system can solve existing problems by facilitating the processing of payment data, assisting in the creation of school money payment reports, helping in speeding up the search for payment data, knowing the payment information of tuition without having to come to school, and knowing the payment data report quickly without having to go through a long recap process.

“…Designing a database program describes modeling from the real world into an entity-relation model (E-R Model), better known as an Entity Relational Diagram (ERD) [18,19,20]. ERD is an expression of the actual state into a collection of basic objects called entities through relationships between these entities.…”

During the Covid 19 pandemic, every individual is required to be more creative in carrying out every activity and not make a distance as the reason an activity cannot be carried out. Documentation data, which is usually sent manually by post, will experience difficulties at this time. This research will discuss other ways that can be done to ensure the data exchange process of the Memorandum of Understanding (MOU) between PT. Bank XYZ with partners. The solution that can be implemented is to use the Electronic Data Interchange (EDI) method. EDI is an online-based data exchange method. In other words, the method of exchanging data via postal service is not necessary. Based on this research, the EDI method can meet users' needs in terms of exchanging or sending documentary data on the MOU between PT. Bank XYZ with partners. The method used in building this system design is analyzing the running system and designing the system with UML tools. The final result of the validation test of the system design through the FGD method states that the e-approval system application design of the MOU is by the specifications of the functional requirements required by the user.
