Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kualitas pelayanan terhadap minat wisatawan dalam melakukan pemesanan kamar di Nikita Palace Hotel Bukittinggi. Latar belakang penelitian adalah rendahnya minat wisatawan untuk memesan kamar, meskipun hotel telah berupaya memberikan pelayanan yang responsif, ramah, dan memperhatikan kebutuhan tamu. Penelitian ini menggunakan metode deskriptif kuantitatif dengan teknik accidental sampling dan pengumpulan data primer melalui kuesioner. Analisis data dilakukan menggunakan uji regresi linear sederhana dan uji hipotesis dengan bantuan SPSS 24. Berdasarkan hasil analisis yang dilakukan dengan menggunakan SPSS 24 maka hasil penelitian yang didapat bahwa kualitas pelayanan tidak berpengaruh siginifikan terhadap minat wisatawan dengan nilai probabilitas 0,348 yang lebih besar dari signifikansi 0,05 (0,348 > 0,05) pada a 5% dengan nilai koefisien -,120, dan nilai adjusted R-Squared sebesar -0,001, dan nilai uji t hitung 0,944 < 1,663 t tabel, artinya kualitas pelayanan tidak memiliki pengaruh terhadap minat wisatawan. Nilai koefisien Beta sebesar -0,120 menunjukkan bahwa meningkatnya kuaalitas pelayanan setiap satu satuan akan menurunkan minat wisatawan sebesar -0,120.. Artinya, peningkatan kualitas pelayanan justru menurunkan minat wisatawan untuk memesan kamar di hotel tersebut. Temuan ini mengindikasikan perlunya evaluasi lebih lanjut terhadap aspek pelayanan yang diberikan agar dapat meningkatkan minat wisatawan.

Abstract

Marketing strategies in culinary micro, small, and medium enterprises (MSMEs) have become a focus in various previous studies; however, research that specifically discusses marketing strategies in maintaining consumer loyalty based on the perspective of Islamic business management remains limited. This study aims to analyze the marketing strategies implemented by Warung Joyoboyo in maintaining consumer loyalty. This study employed a qualitative approach with a case study design. The research participants were consumers of Warung Joyoboyo selected through the purposive sampling technique. Data were collected through interviews, observation, and documentation and were then analyzed using qualitative descriptive techniques through the stages of data reduction, data presentation, and conclusion drawing. The results show that marketing strategies through the elements of the marketing mix, which include product, price, place, and promotion, play a role in shaping consumer loyalty. Product quality, affordable prices, strategic location, and word-of-mouth promotion are the main factors that encourage repeat purchases and recommendations to other consumers. However, the level of consumer loyalty shows variation influenced by individual experiences and preferences. These findings contribute to the development of marketing studies, particularly the integration of the marketing mix concept with the perspective of Islamic business management, and broaden understanding of marketing strategies in culinary MSMEs. The conclusion of the study emphasizes that the implementation of effective and ethical marketing strategies plays an important role in increasing consumer loyalty. The practical implication is that MSME actors need to maintain product quality and service consistency so that consumer loyalty can be sustained.

Abstract

The development of the Islamic capital market and the growing dominance of young investors have not been fully accompanied by increased investment interest among Generation Z, particularly in Padang City. This study aimed to analyze the effects of education and advances in digital technology on Generation Z’s interest in investing in the Islamic capital market, both partially and simultaneously. The study employed a quantitative approach with a survey design involving 100 respondents aged 17–28 years who were selected through accidental sampling. Primary data were collected using an online Likert-scale questionnaire and analyzed through multiple linear regression, t-tests, an F-test, and the coefficient of determination with the assistance of SPSS 24. The results showed that education had a positive and significant effect on investment interest, whereas advances in digital technology had no significant partial effect. Nevertheless, the model incorporating education and advances in digital technology simultaneously had a significant effect on investment interest. These findings indicate that the availability and convenience of technology are insufficient to foster investment interest without adequate understanding. This study concludes that education plays an important role in encouraging Generation Z’s interest in investing in the Islamic capital market. The results imply the need to develop investment education programs integrated with the use of digital technology to expand Generation Z’s participation in the Islamic capital market. Keywords: Investment Education; Generation Z; Investment Interest; Islamic Capital Market; Digital Technology

Abstract

Financial technology (fintech) has become an important component in the development of Islamic banking services, particularly in enhancing the convenience, speed, and accessibility of digital services. However, empirical studies on the effect of fintech on the accountability of Islamic banking services at the branch level, particularly based on the perceptions of customers of Bank Syariah Indonesia (BSI) Bukittinggi Branch, remain limited. This study aimed to analyze the effect of fintech on the accountability of Islamic banking services among customers of the BSI Bukittinggi Branch. The study employed a quantitative approach using field research and a survey design. The respondents comprised 101 BSI customers who used its digital services and were selected through purposive sampling. Data were collected using a questionnaire and subsequently analyzed through validity, reliability, and normality tests and simple linear regression with the assistance of SPSS. The results showed that fintech had a positive and significant effect on the accountability of Islamic banking services, as indicated by the regression equation Y = 3.419 + 0.772X + ε and a value of p < .001. The adjusted R² value of .489 indicated that fintech explained 48.9% of the variation in service accountability, while the remaining 51.1% was associated with other factors outside the research model. These findings provide empirical evidence that fintech optimization plays an important role in enhancing the transparency, accountability, and governance quality of Islamic banking services. The practical implications of this study emphasize the need for BSI to improve the quality of its digital services, maintain system stability, and strengthen its mechanisms for handling customer complaints to support sustainable service accountability.
