Abstract

Researchers believe that the Website Quality variable can have a positive relationship and a positive influence on purchasing decisions because buyers can find out detailed information on the website, can bind buyers, and so on (Jonathan Sarwono, 2016). Apart from that, researchers believe that a brand's reputation can strengthen the relationship between website quality and purchasing decisions(Azhari, 2015). This research is quantitative research with an explanatory approach, namely research that uses previous research as a stepping stone to find new variations in future research(Sugiyono, 2019). The data in this research was obtained from distributing digital questionnaires to Tiktok shop consumers after being allowed to return with the criteria of at least one shopping trip, if not more than once, then they cannot be called consumers(Abdurahman, 2016). This data is also called pyramid data. The data in this study were analyzed using PLS 4.0. The result this research show the Website Quality variable has a positive relationship and has a significant influence on The reversal decision was due to being positive and the P- Values were below the 0.05 significance level, namely 0.002.In addition, the researcher's belief and subsequent experiments can be proven because the Brnad Reputation variable can moderate the relationship between the two variables above, indicated by the P- Values which are positive and are below the 0.05 significance level, namely 0.000, which is more significant than the direct test of 0.002. This means that with a quality website high and accompanied by a good brand reputation can further strengthen consumers in deciding to purchase a product being offered.

Abstract

This research concerns the construction of a family of minimal surfaces passing through a helical curve. The construction follows the research by Yoon, which employs an approach using the curvature and torsion functions of a given curve. The construction yields a family of generalized helicoids as the minimal surfaces passing through the helical curve.

Abstract

This study proposes a grouped-object fuzzy N-soft framework for decision-making problems involving clustered or partitioned data. The proposed framework extends the conventional fuzzy N-soft set model by integrating the concepts of strait fuzzy sets and strait soft sets, thereby enabling the representation of objects at both the individual and group levels. Unlike existing fuzzy N-soft models, which evaluate objects individually, the proposed approach incorporates group-based partitions while preserving fuzzy membership information and grade rankings.A score-based decision-making procedure is developed to compare groups under multiple evaluation parameters. To illustrate the applicability of the framework, a case study on student performance assessment is considered, where students are grouped according to grade classes and fuzzy membership intervals. The results show that the proposed method successfully identifies the most dominant group and provides an interpretable ranking of grouped objects. The main contribution of this study is the introduction of a grouped-object extension of fuzzy N-soft sets that supports group-level decision making through strait-based partitions. This framework broadens the applicability of fuzzy N-soft sets to decision-making environments where objects naturally occur in clusters or categories. The proposed approach also establishes a foundation for future theoretical developments and practical applications involving grouped data under uncertainty.

Abstract

The National Science Olympiad (OSN) is a prestigious event that involves the best students from various levels of education who have passed a rigorous selection at the district and provincial levels. One way to improve the quality of students in facing the OSN in Science and Mathematics is through structured coaching. The OSN Science and Mathematics Workshop held around the UNAND campus in Padang City is one such effort that has proven successful. The objectives of this workshop include three main aspects, namely improving the competence of high school students in basic science and mathematics, improving students' skills in solving OSN questions and improving the quality of high school education in Padang City. The workshop consisted of three main stages: planning, implementation, and evaluation. In the planning stage, OSN questions from the previous year were collected to be used as learning materials. The implementation stage involved a series of activities, including a pre-test, structured learning through lectures, question simulations, and discussions using audiovisual aids. The evaluation was conducted through a post-test to measure the improvement of students' understanding after attending the workshop. The results of this workshop showed a significant increase in the understanding of students who had participated from 30% to 60%. This illustrates the effectiveness of a sustainable and structured approach in improving student competencies to face OSN competitions in Science and Mathematics. This workshop could become a model for efforts to improve the quality of education in schools around the campus. It can be an inspiration for other educational institutions. Keywords: National Science Olympiad (OSN), Senior High School, workshop Abstrak Olimpiade Sains Nasional (OSN) adalah ajang prestisius yang melibatkan siswa-siswa terbaik dari berbagai tingkatan pendidikan yang telah melewati seleksi ketat di tingkat kabupaten dan provinsi. Salah satu cara meningkatkan kualitas siswa menghadapi OSN bidang IPA dan Matematika adalah melalui pembinaan terstruktur. Workshop OSN IPA dan Matematika yang diselenggarakan di sekitar kampus Universitas Andalas (UNAND) di Kota Padang adalah salah satu upaya yang telah terbukti berhasil. Tujuan dari workshop ini mencakup tiga aspek utama, yaitu meningkatkan kompetensi, keterampilan, dan mutu pendidikan siswa SMA dalam ilmu dasar IPA dan Matematika di Kota Padang. Workshop ini terdiri dari perencanaan, pelaksanaan, dan evaluasi. Pada tahap perencanaan, soal-soal OSN dari tahun sebelumnya dikumpulkan sebagai bahan pembelajaran. Tahap pelaksanaan, dilakukan pre-test, ceramah, simulasi soal, dan diskusi dengan peralatan audiovisual. Evaluasi dilakukan post-test untuk mengukur tingkat pemahaman siswa setelah workshop.
