Abstract

Agribisnis kelapa sawit berperan penting dan strategis untuk mengembangkan ekonomi negara berkembang seperti Indonesia untuk dapat merealisasikan pertumbuhan ekonominya sehingga peningkatan produksi per hektar yang dikembangkan secara berkelanjutan menjadi isu penting dan harus dipikirkan dengan sangat serius melalui optimalisasi sumberdaya dan inovasi pertanian seperti benih, pupuk, dan herbisida. Penelitian ini membahas salah satu inovasi pertanian yang penting untuk diadopsi petani pada konteks kelapa sawit adalah varietas unggul kelapa sawit Tenera.Pemilihan bibit yang tidak tepat akan membawa risiko yang sangat besar di kemudian hari bagi produktivitas tanaman sawit yang akan menyebabkan kerugian bagi petani baik itu kerugian dari segi waktu, dana, dan tenaga. Hal ini baru bisa diketahui setelah tanaman memasuki masa menghasilkan (TM). Bibit berkualitas tinggi sangat dibutuhkan untuk meningkatkan produktivitas kelapa sawit. Maka dari itu petani didorong untuk menggunakan bibit bersertifikat agar dapat meningkatkan produktivitas kelapa sawit.

Abstract

The growth of artificial intelligence (AI) in healthcare is causing big shifts in management roles and how ready organizations are, especially in private hospitals. In Medan City, rising competition, a small healthcare workforce, and strict accreditation requirements all make it even more important to use digital technology to make operations more efficient. This study seeks to examine the impact of AI on organizational readiness, utilizing management performance as a mediating variable. Quantitative approaches were employed via a survey of managers and administrative personnel at private hospitals, and the data were analyzed using path analysis with SPSS. The findings indicate that AI exerts a favorable and considerable influence on management performance, which in turn directly enhances organizational readiness. Additionally, managerial performance has been demonstrated to mediate the relationship between AI and organizational readiness. These findings address a research gap concerning the mechanisms of AI's role in the managerial context of hospitals in developing countries and offer practical implications for fortifying digital strategies, cultivating human resource competencies, and augmenting organizational capabilities in response to technology-driven healthcare transformation.

Abstract

This study aims to identify and analyze the factors that affect service quality in the implementation of research and community service programmes at private universities under the coordination of the Higher Education Service Institution (LLDIKTI) Region I. As part of its mandate, LLDIKTI is responsible for supervising, assisting, and improving the quality of higher education services, particularly in research and community service funded through national grant schemes. Using a quantitative approach, data were collected from 102 respondents consisting of heads of Research and Community Service Institutions (LPPM) at private universities who received BOPTN grant funding. Data analysis was performed using SPSS version 25, including validity testing, reliability testing, classical assumption tests, multiple linear regression, t-test, F-test, and coefficient of determination. The results show that the variables tangibles, responsiveness, and assurance have a positive and significant effect on service quality, indicating that physical facilities, the promptness of service, and confidence in institutional capability strongly shape user perceptions. In contrast, reliability and empathy show no significant effect on service quality. Simultaneously, all variables significantly influence service quality, demonstrating that service quality is multifaceted and reliant on interconnected dimensions. These findings highlight the need for LLDIKTI Region I to strengthen its physical infrastructure, improve responsiveness, and ensure the professionalism of its services to enhance satisfaction among higher education institutions.

Abstract

This study aims to examine the influence of work environment and job satisfaction on employee performance with loyalty serving as an intervening variable at UPTD Puskesmas Parigi. As public health institutions increasingly emphasize service quality, employee attitudes, work atmosphere, and organizational commitment become critical components that determine performance outcomes. The study uses a quantitative approach with a census sampling method involving all 52 employees at Puskesmas Parigi. Data were collected through structured questionnaires and analyzed using multiple linear regression and Sobel test procedures to assess both direct and mediating effects. The results reveal that the work environment has a positive and significant impact on both loyalty and performance, indicating that comfortable, safe, and supportive workplace conditions contribute directly to improved performance. Job satisfaction significantly influences performance but does not significantly influence loyalty, suggesting that satisfaction enhances productivity but may not necessarily strengthen commitment. Employee loyalty significantly contributes to performance, confirming its role in increasing employees’ willingness to give their best. Furthermore, loyalty does not mediate the influence of work environment on performance but does mediate the relationship between job satisfaction and performance. These findings highlight the importance of cultivating a positive work atmosphere and managing satisfaction proactively to ensure optimal employee performance in healthcare settings.

Abstract

Mangrove ecosystems have a crucial role as coastal fortresses as well as supporting the ecological and economic balance of the community. As a tangible manifestation of the implementation of the Tri Dharma of Higher Education, the Center for Excellence in Science and Technology (PUI) of the University of North Sumatra in synergy with Universitas Prima Indonesia held a 3rd Summer Course with the theme "International Community Service for Conservation and Mangrove Ecosystem Service". This international community service activity was held on September 6-7, 2025 in the Mangrove Forest of Beras Basah Village, Lalat Regency. The programme involves multidisciplinary and cross-border collaboration, bringing together experts and students from renowned global institutions, including Dilliman College, Chulalongkorn University (Thailand), Universiti Sultan Zainal Abidin (Malaysia), as well as the National Research and Innovation Agency (BRIN). PUI Bina Ruang UNPRI also actively participates in conducting in-depth observations on the correlation between the preservation of mangroves and the spatial layout of human life in coastal areas. Through a participatory and educational approach, this activity not only aims to accelerate environment-based national development, but also formulate innovative solutions in maintaining mangrove ecosystem services for global sustainability.

Abstract

This study analyzes the effects of marketing strategy and the ease of use of the MyPertamina application on purchasing decisions for Pertamax, with customer satisfaction as a mediating variable in Medan City. A quantitative approach was employed using SEM-PLS with a sample of 100 MyPertamina users. The results indicate that marketing strategy has a positive and significant effect on customer satisfaction and on purchasing decisions. The ease of use of the application has a positive and significant effect on customer satisfaction, but it does not directly affect purchasing decisions. Customer satisfaction has a positive and significant effect on purchasing decisions and mediates the effects of marketing strategy and ease of use on purchasing decisions. These findings emphasize that improving purchasing decisions is more effectively achieved by strengthening customer satisfaction, both through marketing strategies and by enhancing the application’s ease of use. Practically, PT Pertamina should optimize its digital marketing and develop a MyPertamina application that is simple, reliable, and user-experience oriented to encourage Pertamax purchases.
