Abstract

This study was conducted at Bio Live Healthy Home, located in Sei Bamban District, Serdang Bedagai Regency. The primary objective of this research is to determine how lifestyle, reference groups, and consumer attitudes influence the decision to use services offered by the institution. In a rapidly growing health and wellness industry, understanding consumer behavior is essential to improve service quality and increase customer engagement. To achieve the research objectives, the study employed a survey method with a quantitative approach. The target population consisted of service users, and a sample of 92 respondents was selected. Data collection was carried out through a combination of observation, interviews, documentation, and the distribution of structured questionnaires. The questionnaire was designed to capture variables related to lifestyle, reference groups, attitudes, and service usage decisions. Before conducting the main analysis, the data were tested for validity and reliability to ensure that the instrument accurately measured what it intended to measure. Furthermore, classical assumption tests, including normality, multicollinearity, and heteroscedasticity tests, were conducted to confirm the feasibility of using a multiple linear regression model. The analysis was performed using the Statistical Package for the Social Sciences (SPSS) software. The results of the study revealed that lifestyle, reference groups, and attitudes each had a significant and positive influence on the decision to use services at Bio Live Healthy Home. This indicates that individuals with health-conscious lifestyles, influenced by their social environment and holding positive attitudes toward wellness services, are more likely to engage with the services offered. Moreover, these three factors collectively contributed to a meaningful explanation of the variation in consumer decisions. In conclusion, the findings highlight the importance for service providers to consider psychological and social factors when designing marketing strategies.

Abstract

This study aims to identify and measure the influence of customer relationships, customer satisfaction, and brand image on customer loyalty at Ryandini’s Sweet Chicken Claw business, located in Sei Sijenggi Village, Hamlet III, Perbaungan District, Serdang Bedagai Regency. A quantitative research method was employed, with data collected through observation, documentation, and questionnaires. The questionnaires used a Likert scale as a measurement tool to assess respondents’ opinions accurately. Data analysis was conducted using several stages, including validity and reliability tests, classical assumption testing, and multiple linear regression analysis, processed through SPSS version 22. These methods were used to ensure the validity of the instrument and the consistency of the findings. The research findings demonstrate that customer relationships have a significant and positive effect on customer loyalty. Customers who feel connected and valued by the business are more likely to remain loyal. Likewise, customer satisfaction—reflecting the extent to which customers' expectations are met or exceeded—has a strong and positive influence on loyalty. In addition, the brand image of the business, which encompasses customer perceptions and reputation of the product, also significantly influences loyalty in a positive direction. Furthermore, the simultaneous analysis of customer relationships, customer satisfaction, and brand image shows that all three variables jointly have a significant and positive impact on customer loyalty. This means that enhancing these three factors can strengthen customer retention and long-term commitment. These results provide valuable insights for small business owners in the food and beverage industry. Focusing on building strong relationships with customers, consistently delivering satisfaction, and maintaining a positive brand image are essential strategies to increase loyalty. For Ryandini’s Sweet Chicken Claw and similar businesses, these findings offer practical guidance for developing customer-centered marketing strategies in an increasingly competitive market.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) merupakan sektor yang amat vital sebagai penyangga ekonomi daerah dalam menciptakan pertumbuhan dan lapangan pekerjaan. Namun, pentingnya sektor ini belum diimbangi dengan kontribusi terhadap nilai Produk Domestik Bruto (PDB) dan nilai ekspor yang relatif masih rendah bila dibandingkan dengan populasi pelaku UMKM sebanyak 99,9%. Menjadi seorang wirausahawan memerlukan kerja keras, keuletan, kreatif dan inovatif serta keberanian untuk mengambil risiko. Metode pelaksanaan dalam program ini yaitu mengacu kepada permasalahan yang ada di lapangan yaitu masih mengalami perkembangan dalam produksi yang masih manual dengan cara yang tradisional karena ketiadaan alat produksi yang memadai serta kurangnya pengetahuan dalam proses produksi sehingga berdampak pada hasil produksi yang minim dari segi kuantitas dan kurang dalam hal kualitas. Produk masih dikemas dengan cara yang terlalu sederhana dan kurang memperhatikan standar kebersihan dan kesehatan sehingga kurang menarik minat pembeli. Selain itu,harga jual produk yang relatif mahal sehingga masyarakat enggan untuk membeli. Kegiatan Pengabdian Kepada Masyarakat dilakukan dengan menggunakan pendekatan “andragogi”, yaitu mengutamakan partisipasi dari hasil pelaksanaan pengabdian yang dicapai sesuai tahun pelaksanaan pengabdian.

Abstract

Advances in digital technology have encouraged small and medium-sized enterprises (SMEs) to shift to cashless payment systems, including the Quick Response Code Indonesian Standard (QRIS). This study aims to assess the effect of QRIS implementation on the cost structure, profitability, and break-even point (BEP) of Heiho Healthy Food Catering in Depok in 2024. The method used is BEP analysis, taking into account an additional cost of 0.3% in the form of the Merchant Discount Rate (MDR) for QRIS transactions. The results show that before implementing QRIS, the contribution margin per unit was IDR 21,451.61 with a BEP of 3,131 units. After using QRIS without any adjustment to the selling price, the margin decreased to IDR 21,296.77, and the BEP increased to 3,155 units, indicating a higher risk to profitability if sales decline. However, increasing the selling price by 0.3% to IDR 50,150 per unit raised the margin to IDR 21,446.77, and the BEP decreased to 3,134 units, approaching the level before QRIS implementation. The findings indicate that QRIS can still generate profit, provided that it is accompanied by an appropriate pricing adjustment strategy to maintain margins and business efficiency.
