Abstract

The development of technology is an inseparable part of human life. Through its development,  technology furthermore produces various reliable tools to assist people in many ways. The technological applications can be in the forms of Google products such as  Google Classroom, Google Form, and Google meet, and also other applications such as Zoom Cloud Meeting, Microsoft Teams  intended to solve various kinds of problems including education field. These technological advancements are popularly used and are indeed very helpful in learning, but sometimes it can’t be hindered that technological applications are not always in accordance with the needs. For example, the practicum learning process in the Information Systems Study Program, Faculty of Science and Technology, Open University, which has no practical application yet. This is because the existing applications are not in accordance with the learning process at the Open University. So, the solution that must be done is to develop an online practicum application (Praton) in the Information Systems Study Program, Faculty of Science and Technology of the Open University. The process of developing a practicum application also cannot be done immediately, so at least there must be an application development design first. Application development design must go through several stages using a software development model. One of the models that can be used is the waterfall model with an object-based approach or commonly referred to as UML (Unified Modeling Language). The results of this software development design are in the form of a software design document and will be sent to a programmer to establish the application. With this application design, programmers will know more about the specifications of online practicum applications that suit the needs of learning process.

Abstract

The implementation of credit transfer at Universitas Terbuka refers to the Rector's Regulation Number 119, 2018. This credit transfer could only be carried out once when students registered themselves at very first time. Recognition of credit transfer is accepted whn accomplishment of courses have been obtained from their previous universities. Through the provision of credit transfer recognition services, students are expected to be able to finish their study faster. Students can apply for credit transfer through the Faculty which would then be proceed by Study Program. Students are required to collect documents such as diplomas, transcripts, descriptions of courses at their previous university, and the submissions for courses intended to be transferred for credit. The documents which are in form of print out would later be processed in their respective Study Programs. During the process, the Study Program compiled the documents manually by recording and determining the courses approved for credit transfer. However, the study Program hasn’t used a special application. Due to this limitation, several problems occurred in the process, such as the absence of filing the credit transfer application documents, the ineffectiveness of storing the credit transfer master block in the Study Program, and the large number of credit transfer applications. These problems often result in delays in the credit transfer process, thus disrupting academic services for students. Therefore, it is necessary to develop a credit transfer application that can assist in the implementation of credit transfer in the Faculty of Science and Technology. The methodology used to develop this credit transfer application is the waterfall model. For design modeling using UML (Unified Modeling Language), while software testing uses Black Box Testing and usability and acceptance tests applied the PSSUQ (Post-Study System Usability Questionnaire) method. From the results of the tests, it showed that Black Box Testing got test results of 100%, while the usability and acceptance tests using the PSSUQ method got 68% of respondents. The conclusion of this study showed that the application is ready to use and the users Agree/Good/Like on the development of a web-based credit transfer application at the Faculty of Science and Technology of the Universitas Terbuka (case study of Information Systems Study Program). Kata kunci: Credit transfer, Web, Waterfall, , Black Box Testing, PSSUQ.

Abstract

In the current digital era, the quality of website services is a crucial factor in supporting the effectiveness and efficiency of information systems, including the Information Systems Study Program Field Work Information System (SIPKL) at Universitas Terbuka. However, currently there is no in-depth evaluation of the quality of SIPKL services from a user perspective. This research aims to review the service quality of the SIPKL website as a whole and measure the level of user satisfaction with the services provided. To achieve this goal, the WebQual 4.0 method is used which measures three main dimensions of service quality, namely usability, information quality, and interaction quality. In addition, the Importance Performance Analysis (IPA) method is applied to evaluate the importance and performance of each service attribute being measured, so as to identify areas that require improvement. Data was collected through a survey with 100 respondents from Information Systems study program students who had used the SIPKL website. The research results show a value of 101.6% for the level of conformity, which indicates that the SIPKL website service performance has met or even exceeded user expectations and interests. Meanwhile, the gap value is categorized as “Good” with a positive value of 0.08 or >0. Indicators that require improvement are in quadrants II and III. Overall, this research provides strategic recommendations for SIPKL website managers to improve service quality so that it is more optimal in supporting students' needs in undergoing PKL.

Abstract

The development of generative artificial intelligence (GAI) has impacted various fields, including higher education. This research examines the use of GAI as an evaluator and feedback provider in distance legal education. This study tested five GAI models: ChatGPT, Perplexity, Gemini, Bing, and You, using a sample of 20 students and evaluations from legal experts. Descriptive statistical analysis and non-parametric tests, including Wilcoxon, intraclass correlation coefficient (ICC), Kappa, and Kendall's W, were used to assess accuracy, feedback quality, and usability. The results showed that ChatGPT was the most effective GAI, with the highest mean scores of 4.22 from experts and 4.12 from students, followed by Gemini with scores of 4.15 and 4.07. In terms of binary judgement accuracy, Gemini scored 80%, ChatGPT 60%, while Perplexity, Bing, and You had lower scores. Statistical analysis showed moderate agreement (ICC=0.439) and low alignment (Kappa=-0.058) between the GAIs and expert evaluations, with a Kendall's W value of 0.576 indicating moderate consistency in judgements. These findings emphasize the importance of selecting effective GAIs such as ChatGPT and Gemini to improve academic evaluation and learning in legal education, and pave the way for further innovations in the use of AI.

Abstract

Rekomendasi jalur yang optimum sangatlah dibutuhkan oleh para pemudik. Hal ini disebabkan oleh banyaknya permasalahan yang dihadapi pada saat melakukan perjalanan mudik. Ada asumsi bahwa pengambilan rute yang tepat dapat mengurangi waktu dan biaya yang dibutuhkan selama perjalanan mudik. Oleh karena itu, dibutuhkan suatu perhitungan yang dapat merekomendasikan rute yang efisien pada jalur mudik. Salah satu metode yang dapat menyelesaikan permasalahan jalur terpendek adalah algoritma lebah. algoritma lebah itu sendiri terinspirasi dari perilaku sosial koloni lebah dimana seekor lebah dapat menjangkau sumber makanan dengan rute terdekat. Setelah mereka menemukan makanan lebah–lebah akan kembali kesarang dan menginformasikan sumber makan yang dia temukan kepada teman–temannya dengan menggunakan waggle dance. Dalam penelitian ini pencarian jalur terpendek yang dilakukan lebah tidak hanya mempertimbangkan jarak saja, tetapi mempertimbangkan heuristik lainnya seperti kemacetan, lampu jalan, jalan tol, rawan bencana dan keamanan. Sehingga rute yang dihasilkan merupakan rute yang optimum. Hasil yang didapat dari mengimplementasikan algoritma lebah untuk pencarian jalur terpendek dengan mempertimbangkan heuristik adalah rute jalur optimum yang bisa dilalui dari kota awal ke kota tujuan beserta panjang jalur yang dapat ditempuh.
