Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh fanatisme supporter Persebaya Surabaya terhadap loyalitas konsumen pada brand Aza Apparel. Penelitian ini menggunakan pendekatan kuantitatif dengan metode analisis regresi linier sederhana. Populasi dalam penelitian ini yaitu supporter Persebaya Surabaya yang pernah membeli produk Aza Apparel. Sampel yang digunakan sebanyak 180 responden yang dipilih melalui teknik purposive sampling. Data dikumpulkan melalui kuesioner dengan skala Likert 1-5. Hasil penelitian menunjukkan bahwa seluruh item pada variabel fanatisme (X) dan loyalitas konsumen (Y) dinyatakan valid dan reliabel dengan nilai Cronbach's Alpha sebesar 0,754 dan 0,777. Hasil analisis regresi menunjukkan bahwa fanatisme supporter berpengaruh positif dan signifikan terhadap loyalitas konsumen dengan nilai t-hitung sebesar 12,191 (Sig. = 0,000 < 0,05). Persamaan regresi yang diperoleh adalah Y = 4,991 + 0,572X dengan koefisien determinasi (R²) sebesar 0,455, artinya 45,50% variasi loyalitas konsumen dapat dijelaskan oleh fanatisme supporter. Korelasi Pearson antara kedua variabel sebesar r = 0,675 yang termasuk kategori kuat. Hasil ini membuktikan bahwa semakin tinggi tingkat fanatisme supporter maka semakin tinggi pula loyalitas konsumen terhadap brand Aza Apparel.

Abstract

Integrasi teknologi wearable dalam Pendidikan Jasmani (PJ) menawarkan solusi pragmatis untuk pemantauan fisiologis massal, namun validitas smartwatch fotoplethysmography (PPG) untuk mengukur denyut jantung maksimal (HRmax) selama tes lapangan intensitas tinggi yang autentik pada remaja masih kurang diteliti. Studi ini bertujuan untuk mengevaluasi validitas konkuren smartwatch PPG komersial terhadap strap dada elektrokardiografi (EKG) (Polar H10). Desain kuantitatif deskriptif-komparatif digunakan, melibatkan tiga puluh siswa SMA laki-laki sehat yang melakukan Tes Kebugaran Multistage (Tes Beep) untuk mendapatkan HRmax. Data dikumpulkan secara simultan oleh dua pengamat independen. Polar H10 menghasilkan HRmax rata-rata 186,4 ± 8,2 bpm, sedangkan smartwatch mencatat 184,1 ± 9,5 bpm. Normalitas dikonfirmasi melalui Shapiro-Wilk (p > 0,05). Korelasi Pearson menunjukkan hubungan positif yang sangat kuat antara perangkat (r = 0,914, p = 0,000). Uji t sampel berpasangan mengungkapkan perbedaan yang signifikan secara statistik (p = 0,03), dengan smartwatch meremehkan HRmax dengan perbedaan rata-rata 2,3 bpm. Meskipun signifikan secara statistik, perbedaan marginal ini jauh di bawah ambang batas <5 bpm yang ditetapkan untuk kesepakatan yang dapat diterima dalam validasi perangkat wearable. Akibatnya, smartwatch PPG menunjukkan validitas praktis yang tinggi untuk menilai HRmax dalam pengaturan pendidikan jasmani berbasis sekolah, memberdayakan pendidik untuk mengganti palpasi manual yang mengganggu dan tali dada yang mahal dengan alat yang mudah diakses dan andal untuk menentukan intensitas latihan.

Abstract

Badminton instruction in higher education is commonly dominated by isolated technical drills, limiting students' ability to transfer acquired skills into authentic match situations that require tactical awareness and rapid decision-making. This study aimed to develop and evaluate the effectiveness of a Virtual Reality (VR)-Based Badminton Simulating In-Game Scenarios learning model for improving university students' badminton performance. A Research and Development (R&D) approach employing the ADDIE instructional design model was adopted, comprising the phases of analysis, design, development, implementation, and evaluation. The developed VR application was implemented with 24 undergraduate students enrolled in a badminton course using a one-group pre-test–post-test design. Data were collected through expert validation, badminton skill assessment, observation, and student response questionnaires. The normality of the data was examined using the Shapiro–Wilk test, while differences between pre-test and post-test scores were analyzed using the Wilcoxon Signed-Rank Test. The results demonstrated statistically significant improvements in player performance (Z = –2.718, p = 0.007) and match-winning performance (Z = –3.051, p = 0.002) following the VR intervention. These findings indicate that the developed learning model effectively enhances badminton performance by providing immersive and representative learning environments that integrate technical execution, tactical awareness, perception–action coupling, and contextual decision-making. This study contributes to technology-enhanced sport education by proposing an innovative VR-based instructional model that extends conventional badminton learning beyond isolated technical practice toward authentic game-based learning experiences.

Abstract

This study evaluated the development of athletic performance at the D'Rangers Volleyball Club in Surabaya. Using a qualitative descriptive approach, data were collected through observations, interviews, and documentation involving the club chairman, managers, coaches, and athletes. Source triangulation ensured data validity, while analysis followed the Miles and Huberman model of data reduction, data display, and conclusion drawing. The findings indicate that the club has achieved good performance development, demonstrated by winning the 2025 Surabaya Mayor's Championship. Athlete development is implemented systematically through talent identification, age-based grouping, regular training, and match simulations. The training program is well structured, covering technical, physical, tactical, and mental components across preparation, competition, and transition phases. Although financial management is considered adequate through sponsorships and membership fees, limitations in training facilities and equipment remain. A positive psychosocial environment, characterized by supportive coaches, the absence of seniority, and enjoyable training, further contributes to athlete development. Overall, the D'Rangers Volleyball Club has shown consistent performance growth, although improvements in infrastructure are needed to sustain future achievements.

Abstract

Event management is one of the competencies that sports students need to have to support their readiness to enter the workforce in the sports industry. However, students' practical experience in managing events is still limited, so a training program that can integrate conceptual learning with practical experience is needed. This community service activity aims to improve sports students' knowledge of event management through experiential learning-based training. The program was implemented using a participatory approach with a one-group pretest–posttest design involving 30 students from the Faculty of Sport and Health Sciences, Surabaya State University. The training consisted of lectures, discussions, case studies, workshops, and simulations of organizing sports events. Evaluation was carried out using a knowledge test and a participant satisfaction questionnaire. The data were analyzed descriptively, using the Shapiro–Wilk normality test, paired sample t-test, effect size (Cohen's d), and Normalized Gain (N-Gain). The results showed that the post-test score increased significantly compared to the pre-test (p < 0.001) with a Cohen's d value of 2.84 indicating a very large effect and an N-Gain value of 0.62 in the moderate category. Furthermore, participant satisfaction reached 90.45%, categorized as very good, particularly in terms of resource person competency and learning methods. These findings demonstrate that experiential learning-based training effectively enhances student knowledge while providing a positive learning experience relevant to the needs of organizing sporting events. This program has the potential to become a model for developing event management competencies that can be replicated in universities and sporting organizations.
