Abstract

Improving students' reading interest is one of the efforts to support the achievement of quality education, as part of the Sustainable Development Goals (SDGs). The 2025 Thematic Literacy Community Service Program (KUKERTA) by Universitas Riau, held in Dayang Suri Village, Bunga Raya Sub-district, Siak Regency, represents a tangible form of multisectoral collaboration in partnership with the National Library of Indonesia to promote a planned, structured, and sustainable literacy culture. This community service activity employed a quantitative descriptive approach. Data collection methods included observation, documentation, and the distribution of questionnaires to sixth-grade students at SDN 09 Dayang Suri who participated in the literacy activities. One of the key literacy initiatives was regular read-aloud sessions aimed at fostering students’ interest in reading, improving reading comprehension, and cultivating a literacy culture in the school. The results of the questionnaire indicate that 30% of students have a very good reading interest level, 40% are categorized as good, and 30% are categorized as adequate. This data is supported by the higher frequency of library visits, enthusiasm during the read-aloud sessions, and the growing confidence of students in reviewing the content of the texts they read. These findings provide an overview of the reading interest conditions of students in Dayang Suri Village, while also demonstrating the potential for multisectoral collaboration utilizing the school library and reading aloud activities as parts of efforts to support literacy and quality education.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh reputasi organisasi, aksesibilitas layanan, dan kualitas komunikasi pemasaran terhadap kepercayaan serta minat bergabung ke Organisasi Advokat di Pekanbaru, dengan kepercayaan sebagai variabel mediasi. Penelitian ini dilatarbelakangi oleh meningkatnya jumlah lulusan Fakultas Hukum di Pekanbaru dan kebutuhan organisasi advokat untuk memahami faktor-faktor yang membentuk minat calon anggotanya, khususnya mahasiswa hukum tingkat akhir di Universitas Riau dan Universitas Islam Riau. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei terhadap 120 responden. Analisis data dilakukan menggunakan Structural Equation Modeling (SEM) berbasis Partial Least Square (PLS) melalui software SmartPLS 4. Instrumen penelitian meliputi lima variabel utama: reputasi organisasi (X1), aksesibilitas layanan (X2), kualitas komunikasi pemasaran (X3), kepercayaan (Z), dan minat bergabung (Y). Hasil penelitian menunjukkan bahwa ketiga variabel independen, yaitu reputasi organisasi, aksesibilitas layanan, dan kualitas komunikasi pemasaran, berpengaruh positif dan signifikan terhadap kepercayaan dan minat bergabung. Selain itu, kepercayaan terbukti berpengaruh positif dan signifikan terhadap minat bergabung serta memediasi pengaruh seluruh variabel independen terhadap minat bergabung. Temuan ini menegaskan bahwa reputasi yang kuat, layanan yang mudah diakses, dan komunikasi pemasaran yang efektif merupakan faktor kunci untuk membangun kepercayaan dan meningkatkan minat mahasiswa hukum untuk bergabung dengan organisasi advokat.

Abstract

The implementation of self-service (the application of Human Computer Interaction) and SMS-based message machine (the application of Computer Mediated Communication) at Riau University Library, has changed the way of communication in services, changed infrastructure, and user satisfaction. This study aims to examine the significance of the influence of these two innovations on service quality, as well as user satisfaction at Riau University Library. This quantitative research that using questionnaire instrument was conducted in January to October 2019 with a population of 14,757 people, and a sample of 200 people. The study uses a Structural Equation Modeling approach with LISREL tools. Data analysis uses Confirmatory Factor Analysis, which produces T-values for each correlation tested. The effect between variables is considered significant if the T-values are greater than 1.96 (critical significance value). From the results of the analysis, it was found that the implementation of self-service had a significant effect on service quality (T-values=4.986) and significant on the satisfaction of users (2.875), while the implementation of SMS-based message machines was significant on service quality (2.576), but not significantly on user satisfaction (0.877).

Abstract

This study is motivated by growing consumer awareness of environmental and sustainability issues; however, a gap remains between attitudes and behavior, known as the green attitude–behavior gap. Consumers with high environmental concern do not necessarily purchase green products. In this context, Eiger, an Indonesian outdoor brand, has developed environmentally friendly products and strengthened its brand image through innovation and sustainability campaigns. Nevertheless, the relatively low contribution of green product sales indicates that a strong brand image does not directly guarantee purchasing decisions. Therefore, word of mouth (WOM) is considered a potential factor bridging this relationship. This study aims to analyze the influence of brand image and green products on purchasing decisions, both directly and indirectly through WOM as a mediating variable among Eiger consumers in Pekanbaru City. A quantitative approach with a causal research design was employed using purposive sampling. Data were collected through Likert-scale questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS. The results indicate that brand image and green products have positive and significant effects on WOM and purchasing decisions. WOM also mediates the effects of both variables on purchasing decisions. These findings highlight the importance of consumer communication, education, and sustainability-value communication in strengthening green marketing strategies and encouraging sustainable green product purchases through trust, social recommendations, and consumer understanding. Penelitian ini dilatarbelakangi oleh meningkatnya kesadaran konsumen terhadap isu lingkungan dan keberlanjutan, namun masih terdapat kesenjangan antara sikap dan perilaku (green attitude–behavior gap). Konsumen yang memiliki kepedulian terhadap lingkungan yang tinggi belum tentu melakukan pembelian produk hijau. Dalam konteks ini, Eiger sebagai merek outdoor lokal Indonesia telah mengembangkan produk ramah lingkungan dan membangun citra merek melalui inovasi serta kampanye keberlanjutan. Namun, kontribusi penjualan produk hijau yang masih relatif rendah menunjukkan bahwa citra merek yang kuat belum secara langsung menjamin keputusan pembelian. Oleh karena itu, word of mouth (WOM) dipandang berpotensi menjembatani hubungan tersebut. Penelitian ini bertujuan menganalisis pengaruh citra merek dan produk hijau terhadap keputusan pembelian, baik secara langsung maupun melalui WOM sebagai variabel mediasi pada konsumen Eiger di Kota Pekanbaru. Penelitian menggunakan pendekatan kuantitatif dengan desain kausalitas dan teknik purposive sampling. Data dikumpulkan melalui kuesioner skala Likert dan dianalisis menggunakan SEM-PLS dengan SmartPLS. Hasil penelitian menunjukkan bahwa citra merek dan produk hijau berpengaruh positif dan signifikan terhadap WOM serta keputusan pembelian. WOM juga terbukti memediasi pengaruh keduanya terhadap keputusan pembelian. Temuan ini menegaskan pentingnya komunikasi antarkonsumen, edukasi, serta penyampaian nilai keberlanjutan dalam memperkuat strategi pemasaran hijau dan mendorong pembelian produk hijau secara berkelanjutan melalui kepercayaan, rekomendasi sosial, dan pemahaman konsumen.

Abstract

This study investigates the numerical solution of fractional differential equations using the Caputo fractional derivative of order . The proposed method is based on the analytical properties of fractional differential equations, which can be reformulated as nonlinear Volterra integral equations of the second kind. A quadratic polynomial interpolation is employed to approximate the solution of the integral equation. Numerical simulations are conducted to evaluate the accuracy and efficiency of the proposed method and to compare its performance with several existing numerical methods. The numerical simulations indicate that the proposed method performs better than the two benchmark methods over short time intervals, especially when using larger step sizes. This makes it more efficient by reducing the overall computational cost.
