Abstract

Weed infestation remains one of the major constraints limiting rice productivity because it competes with crops for water, nutrients, light, and growing space. This study aimed to compare the effectiveness of two selective herbicide formulations containing Bentazone (400 g L⁻¹) + MCPA (60 g L⁻¹), commercially marketed as Basagran® and Bentagram®, in suppressing weeds and supporting the vegetative growth of rice (Oryza sativa L.) cv. Inpari 32. The experiment was conducted in irrigated rice fields in Jombang Regency, East Java, Indonesia, from May to June 2025 using a Completely Randomized Design (CRD). Treatments consisted of six herbicide doses (0.5, 0.75, 1.0, 1.25, 1.5, and 1.75 L ha⁻¹) and an untreated control, each replicated twice. Data on weed diversity, dominance index, weed dry weight, plant height, and tiller number were analyzed using analysis of variance (ANOVA) followed by the Least Significant Difference (LSD) test at the 5% significance level. The application of both herbicides reduced weed diversity, with the Shannon–Wiener diversity index ranging from 1.39 to 1.56 and Simpson's dominance index remaining low (0.22–0.25), indicating effective weed suppression without dominance of any weed species. Basagran had no significant effect (p > 0.05) on plant height, tiller number, or weed dry weight, whereas Bentagram significantly increased tiller number (p < 0.05) while maintaining normal plant growth. Although the highest numerical responses were occasionally observed at 1.75 L ha⁻¹, they were not significantly different from those at 1.5 L ha⁻¹. Therefore, 1.5 L ha⁻¹ was identified as the optimum application rate because it effectively suppressed weeds without causing phytotoxicity or adversely affecting rice vegetative growth. These findings demonstrate that Bentazone + MCPA herbicides can be effectively incorporated into sustainable weed management programs to improve rice cultivation efficiency while minimizing unnecessary herbicide inputs.

Abstract

Increasing competition among educational institutions requires schools to develop innovative strategies that strengthen institutional competitiveness while attracting prospective students. Although the School Literacy Movement (Gerakan Literasi Sekolah/GLS) has primarily been implemented to improve students' literacy competencies, its role as a strategic educational service marketing approach remains underexplored. This study aimed to analyze the implementation of GLS-based educational service marketing and examine the effects of product differentiation, price differentiation, and promotion differentiation on customer interest at SMA Islam Sunan Gunung Jati Ngunut Tulungagung. A Sequential Exploratory Mixed Methods design was employed by integrating qualitative exploration with quantitative verification. Qualitative data were collected through interviews, observations, and document analysis involving school leaders, teachers, and parents. Quantitative data were obtained from 165 students selected using simple random sampling and analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM). The measurement model satisfied the recommended validity criteria with Average Variance Extracted (AVE) values ranging from 0.518 to 0.669. The structural model indicated that product differentiation significantly influenced customer interest (β = 0.179; p = 0.035), price differentiation positively affected customer interest (β = 0.071; p = 0.037), and promotion differentiation showed a positive relationship with customer interest (β = 0.060; p = 0.002). The qualitative findings consistently revealed that literacy-based flagship programs, value-oriented educational pricing, and integrated promotional strategies involving alumni, parents, graduates, print media, and digital platforms strengthened institutional identity and enhanced educational value. The integration of both datasets demonstrates that the School Literacy Movement functions as a strategic educational service marketing framework that increases customer interest and reinforces institutional competitiveness. These findings provide a conceptual contribution by positioning literacy-based educational innovation as a sustainable differentiation strategy for educational institutions.
