Abstract

Environmental sustainability is becoming increasingly significant in tourism education. However, incorporating ecoliteracy into English for Specific Purposes (ESP) courses remains limited within vocational settings. This qualitative case study explored how English for Tourism lecturers at an Indonesian vocational college perceive ecoliteracy integration and the challenges they encounter. Three lecturers participated in semi-structured interviews, which were supplemented with analysis of course materials. The results showed four positive perspectives: ecoliteracy enhances practical learning, encourages a comprehensive understanding of the interconnectedness between society, economy, and environment, aligns with industry sustainability expectations, and develops 21st-century skills. Nonetheless, three major challenges were identified: difficulty aligning the curriculum, limited time for developing materials, and insufficient content knowledge in sustainability education. The study highlights that although lecturers see the value of ecoliteracy, institutional support, such as curriculum reform, resource availability, and ongoing professional development, is crucial for effective integration. These insights contribute to understanding teacher cognition in ESP and have implications for policy and professional growth in vocational training.

Abstract

This study designs and implements an input recommendation system for smallholder coffee agribusiness to close productivity and efficiency gaps. The objective is to assess how decision analysis guides farmers toward input combinations aligned with goals, budget constraints, and field risks. The methodology applies decision analysis: candidate input allocations are formulated; evaluation criteria (yield, total cost, risk exposure, ease of implementation) are specified; criterion weights are elicited through structured judgments; scores are normalized and aggregated; and sensitivity analysis tests robustness to weight and price changes. Results show that the recommendation-based alternative consistently outperforms conventional practice on most criteria, raising productivity while lowering cost per unit of output and reducing risk under volatile weather. Stability of rankings across sensitivity tests indicates durable performance across diverse farmer preferences. The findings highlight the need for targeted technical assistance and financing aligned with recommended inputs to support sustained adoption and scalable replication across regions.
