Abstract

Suatu kompetisi liga sepakbola umumnya digelar dengan sistem kompetisi penuh format kandang-tandang, yaitu setiap dua tim peserta bertanding dua kali dengan bergantian menjadi tuan rumah. Banyaknya pertandingan yang digelar membuat penjadwalan menjadi masalah krusial yang dapat mempengaruhi peringkat. Agar nilai kompetisi tidak berkurang, pihak pengelola kompetisi harus membuat jadwal yang ‘baik’ dan adil untuk semua tim peserta. Dalam hal ini frekuensi pertandingan, frekuensi kandang-tandang dan urutan pertandingan diatur agar seimbang untuk semua tim peserta. Dalam makalah ini disajikan suatu metode penjadwalan yang ‘baik’ dengan menggunakan pendekatan persegi Latin (Latin squares). Metode penjadwalan untuk liga dengan jumlah peserta ganjil akan disajikan terlebih dahulu. Selanjutnya metode diperluas untuk jumlah peserta genap. Lebih lanjut dibuktikan pula bahwa metode ini dapat diterapkan untuk liga dengan jumlah peserta berapapun. Kata Kunci: Kompetisi liga sepakbola, Format kandang-tandang, Penjadwalan pertandingan, Persegi Latin.   A ‘Good’ Scheduling Method for Football League Competition by Using Latin Squares Approach Abstract A football league competition is usually held in a double round-robin competition on home and away format. That is, every team will play against each other team twice, once as the host, once as the visitor. Because of the high number of matches that should be held, the match scheduling will be crucial problem which can affect the competition standings. In order to keep the competitive value, the competition’s administrator must create a ‘good’ and fair schedule for all participating teams. In this case, frequencies of matches, home and away frequencies and order of the matches are set to be balanced for all participating teams. In this article, we will introduce a ‘good’ scheduling method by using Latin squares approach. First we will give the method for odd number of participants. Then, the method is extended to even number of participants. Furthermore it is also proved that this method can be applied for any number of participants in a league. Keywords: Football competition, Home-away format, Match scheduling, Latin Squares.

Abstract

This study aims to determine the magnitude of the influence of Social Media Marketing during campaigns through Instagram on Yogurt X product purchase decisions. The study population was Instagram followers of Yogurt X. Large samples to be taken in this study can be determined through the slovin formula. Researchers used an error tolerance (e) of 10 percent and a population of 29,300 followers of Instagram Yogurt X. Based on the results of these calculations, it can be seen that the sample in this study amounted to 100 people. Sampling in this study was carried out by Nonprobability Sampling. The sampling technique in this study used incidental sampling. Incidental sampling is a sampling technique based on chance, i.e. anyone who incidentally meets the researcher can be used as a sample. The results of the Partial Test (Test t) show that Context (X1), Collaboration (X3) and, Connection (X4) have a significant effect on Yogurt X Purchasing Decisions, while Communication does not have a significant effect on Yogurt X Purchasing Decisions. The magnitude of the influence of Sub Variability (Context, Communication, Collaboration, Connection) on sequential Purchasing Decisions is Context 18.8 percent, Communication 2.94 percent, Collaboration 22.21 percent, Connection 17.47 percent. The results of the Simultaneous Test (Test F) show that Social Media Marketing Yogurt X through Instagram social media affects Purchase Decisions. The magnitude of the influence of the independent variable on the dependent variable was 61.4 percent, while the remaining 38.6 percent was influenced by other variables that were not studied

Abstract

This study aims to examine the impact of using information and communication technology (ICT) in history education on students' motivation, understanding, and engagement. A mixed methods approach, combining quantitative and qualitative data collection, was employed to gather comprehensive insights. Based on the survey results from 100 history education students, 78% reported increased motivation, and 65% indicated enhanced understanding of historical materials after using e-learning platforms. Interviews with 10 history teachers revealed that e-learning facilitates the delivery of complex content and boosts student participation in class discussions. Additionally, e-learning provides high flexibility for students to learn anytime and anywhere, addressing the limitations of traditional classroom settings. The findings suggest that integrating ICT into history education enriches the learning experience, improves academic outcomes, and makes history education more engaging and relevant in the digital era.
