Abstract

Abstract: This study aims to determine the simultaneous and partial effects of Kualitas layanan, E-WOM, and Customer Experience on consumer satisfaction. The sample consisted of 96 respondents. The data analysis technique used multiple linear regression. The regression results produced the equation: Y = 1,901 + 0,315X1 + 0,561X2 + 0,407X3. The F-test result shows an Fcount (33.997) > Ftable (2.70), indicating that kualitas layanan, E-WOM, and customer experience simultaneously have a significant effect on consumer satisfaction. The t-test results show that, partially, kualitas layanan has a positive effect on consumer satisfaction because tcount (2.145) > ttable (1.986), E-WOM has a positive effect on consumer satisfaction because tcount (6.240) > ttable (1.986), and customer experience also has a positive effect on consumer satisfaction because tcount (3.386) > ttable (1.986). The R² test result shows an Adjusted R Square value of 0.515, meaning that the independent variables consisting of kualitas layanan, E-WOM, and customer experience are able to explain consumer satisfaction by 51,5%, while the remaining 48,5% is explained by other variables not included in this study.

Abstract: This study aims to determine the simultaneous and partial influence of Online Customer Review, Online Customer Rating and Consumer Trust on Purchase Decisions of Hanasui Products on Shopee among Students of the Faculty of Economics, Asahan University. The type of research used is quantitative research with causal associative properties. Data analysis uses multiple linear regression, while sample determination uses a non-probability sampling method with the Cochran approach totaling 100 respondents. The data collection technique was carried out by distributing questionnaires to students of the Faculty of Economics, Asahan University who had purchased Hanasui products on Shopee. Validity and reliability tests were carried out to ensure the research instrument was suitable for use. The results of the study indicate that simultaneously Online Customer Review, Online Customer Rating and Consumer Trust have a significant effect on Purchase Decisions of Hanasui Products on Shopee among Students of the Faculty of Economics, Asahan University. Partially, Online Customer Review has a positive and significant effect on Purchase Decisions, Online Customer Rating has a positive and significant effect on Purchase Decisions, and Consumer Trust also has a positive and significant effect on Purchase Decisions. The Consumer Trust variable is the most dominant variable in influencing Purchase Decisions because consumers tend to consider the sense of security and confidence in the product and seller before making online transactions. Based on the coefficient of determination (R²), it is known that online customer reviews, online customer ratings, and consumer trust are able to explain variations in purchasing decisions, while the remaining factors are influenced by other factors outside this study. This research is expected to contribute to the development of marketing management science, particularly in the fields of consumer behavior and digital marketing. Keywords: Online Customer Reviews, Online Customer Ratings, Consumer Trust, Purchasing Decisions.   Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh secara simultan dan parsial Online Customer Review, Online Customer Rating dan Kepercayaan Konsumen terhadap Keputusan Pembelian Produk Hanasui di Shopee pada Mahasiswa Fakultas Ekonomi Universitas Asahan.

Abstract: This study aims to analyze the performance appraisal system implemented at CV. Anugerah Bersama Cahaya and examine the influence of subjectivity in the appraisal process on employee work discipline. The research employed a qualitative approach with a case study design. Data were collected through in-depth interviews, observations, and documentation involving the company leader, division coordinators, and employees. Data analysis was conducted using the interactive model of Miles, Huberman, and Saldaña, including data condensation, data display, and conclusion drawing and verification. The findings reveal that the performance appraisal system remains informal and lacks standardized performance indicators. The appraisal process relies heavily on managerial observation and personal judgment, resulting in subjectivity, unclear performance standards, and perceptions of unfairness among employees. These conditions affect employee discipline, particularly in terms of compliance with organizational rules, punctuality, and job responsibility. The findings emphasize that objectivity, transparency, and consistency in performance appraisal are essential factors in fostering perceptions of fairness and strengthening employee work discipline. This study contributes to the human resource management literature by highlighting the relationship between appraisal subjectivity and employee discipline within the context of small and medium-sized enterprises. Keywords: performance appraisal, appraisal subjectivity, work discipline, organizational justice, human resource management.   Abstrak: Penelitian ini bertujuan untuk menganalisis sistem evaluasi kinerja yang diterapkan di CV. Anugerah Bersama Cahaya serta menjelaskan pengaruh subjektivitas dalam proses evaluasi terhadap disiplin kerja karyawan. Penelitian menggunakan pendekatan kualitatif dengan desain studi kasus. Data dikumpulkan melalui wawancara mendalam, observasi, dan dokumentasi terhadap pimpinan, koordinator divisi, dan karyawan perusahaan. Analisis data dilakukan menggunakan model interaktif Miles, Huberman, dan Saldaña yang meliputi kondensasi data, penyajian data, serta penarikan dan verifikasi kesimpulan. Hasil penelitian menunjukkan bahwa sistem evaluasi kinerja masih bersifat informal dan belum didukung oleh indikator kinerja yang terstandarisasi. Proses penilaian yang sangat bergantung pada pengamatan dan pertimbangan pribadi pimpinan menimbulkan subjektivitas, ketidakjelasan standar, serta persepsi ketidakadilan di kalangan karyawan. Kondisi tersebut berdampak pada disiplin kerja, terutama terkait kepatuhan terhadap aturan, ketepatan waktu, dan tanggung jawab kerja. Temuan penelitian menegaskan bahwa objektivitas, transparansi, dan konsistensi dalam evaluasi kinerja merupakan faktor penting dalam membangun persepsi keadilan dan memperkuat disiplin kerja karyawan. Penelitian ini berkontribusi pada pengembangan kajian manajemen sumber daya manusia, khususnya mengenai hubungan antara subjektivitas evaluasi kinerja dan disiplin kerja pada usaha kecil dan menengah. Kata kunci: evaluasi kinerja, subjektivitas penilaian, disiplin kerja, keadilan organisasi, manajemen sumber daya manusia.

Abstract: Plastic bottle waste remains one of the environmental issues commonly found in university environments. One effort to reduce the use of single-use plastic bottles is by encouraging the habit of using reusable tumblers. This study aims to analyze the effect of carrying tumblers on reducing plastic bottle waste at the State Islamic University of North Sumatra (UIN Sumatera Utara). The research employed a quantitative approach using a survey method through questionnaires distributed to 47 respondents and simple interviews with 6 respondents. Data were analyzed using descriptive statistics to describe students’ habits of carrying tumblers, plastic bottle consumption, environmental awareness, and consistency in tumbler usage. The results indicate that students have a relatively high level of environmental awareness, with mean scores ranging from 2.70 to 2.74. The habit of carrying tumblers has also begun to develop positively, as reflected by a mean score of 2.42 for regular tumbler use. However, practicality remains a major factor leading some students to purchase bottled drinks. Overall, the use of tumblers contributes to reducing plastic bottle consumption on campus, although greater behavioral consistency and better campus facilities are needed to achieve more optimal outcomes. Keywords: Tumbler, Plastic Waste, Environmental Awareness, Students, Environmentally Friendly Behavior. Abstrak: Permasalahan sampah botol plastik masih menjadi isu lingkungan yang banyak ditemukan di lingkungan kampus.
