Abstract

The study aims at designing the stakeholders on the Guide book of vocabulary and grammar of English list for junior high school students. The background relied on the fact of implementing the 2013 curriculum. The students empirically had difficulty in facing the English examination since a lot of vocabulary was not well-instructed and issued at the test items. The list of vocabulary was difficult to find, and the grammar points were not complete, which determined the reading difficulty. Utilizing a descriptive-quantitative research design, a survey with open-ended questions and a focused-group discussion was done in terms of stakeholders, particularly students, teachers, and assessment instrument involvement. The findings showed that the deliberation included adding and deleting a few parts for improvement purposes, in which they had approved the one designed and presented. The finished product focused on the most important aspects of the vocabulary class, such as the characteristics of the vocabulary glossary, instructions for the guidebook use, and grammar list for the seventh- and eighth-graders. This guidebook serves as a model for the empirical learning circumstance, although it cannot be generalizable.

Abstract

This study investigated the efficacy of Artificial Intelligence (AI)-based Text-to-Speech (TTS) technology in Indonesian pronunciation training for Foreign Speakers (BIPA), addressing a notable research gap concerning its specific effectiveness and learner perceptions. Employing a mixed-method quasi-experimental design with experimental (n=20) and control (n=20) groups, the research utilized pronunciation tests, perception questionnaires, and interviews. Based on the paired sample t-test, findings showed that AI TTS was significantly more effective than conventional methods in improving BIPA learners’ pronunciation in accuracy, fluency, and intelligibility. This efficacy is attributed to AI's capacity for immediate, personalized feedback and objective analysis. The qualitative data analysis revealed that learners reported overwhelmingly positive perceptions regarding AI TTS's effectiveness, engagement, and confidence-boosting impact, appreciating its non-judgmental and accessible nature. However, limitations emerged concerning voice naturalness, intonation accuracy, and the interpretation of contextual nuances. Concerns were also raised about potential over-reliance on AI, technical reliability, and data privacy. These findings strongly advocate for a blended learning approach in BIPA pronunciation instruction, strategically leveraging AI's strengths while preserving the essential value of human teaching for higher-order linguistic and cultural competence. The study contributes to applied linguistics by providing empirical insights into AI applications in second language acquisition beyond English contexts and offers practical guidance for developing adaptive, user-centered BIPA curricula and fostering responsible AI integration.

Abstract

Teacherpreneurship has emerged as a strategic response to the growing demand for teachers who are not only pedagogically competent but also creative, opportunity-driven, and digitally literate. However, limited empirical evidence explains how organizational participation and character formation interact to shape entrepreneurial readiness among prospective vocational teachers, particularly within the Merdeka Belajar framework. This study employs an explanatory sequential mixed-methods design to examine the relationships between organizational participation, character development, and teacherpreneurship. Quantitative data were collected from 120 students using validated instruments, followed by qualitative interviews, focus group discussions, and observations involving 24 purposively selected participants. Statistical analyses, including multiple regression and structural equation modeling, indicate that organizational participation significantly predicts teacherpreneurial readiness, with character development acting as a partial mediator. Students demonstrated strong creativity, leadership, and digital competence, yet faced persistent challenges related to risk-taking, time management, institutional bureaucracy, and limited commercialization literacy. The qualitative findings further reveal identity shifts as students increasingly positioned themselves as innovators capable of developing educational products and digital learning services. SWOT analysis highlights that technological advancement and flexible curriculum opportunities outweigh threats such as competition and automation. The study concludes that teacherpreneurship requires a synergistic integration of experiential organizational learning, character education, and digital entrepreneurship training. Implications are directed toward vocational teacher education institutions to embed credit-bearing organizational engagement, structured mentorship, and micro-grant schemes aligned with Merdeka Belajar policies. These findings contribute to expanding theoretical perspectives on teacherpreneurship while offering practical strategies for strengthening vocational teacher preparation in rapidly evolving educational ecosystems.

Abstract

This study aims to identify and analyze the production cost budget as a control tool used to manage production costs at PT Kalimantan Concrete Engineering Banjarmasin by comparing the company’s budgeted production costs with actual production costs at the end of the period and conducting variance analysis on the deviations. This research employs a quantitative research approach. The data used in this study consist of production cost data from the company’s work plan and budget, as well as their realizations. Data collection techniques included direct case study field observations and literature review. The data analysis method applied in this study is descriptive analysis, which comprehensively describes the data obtained during the research process. The calculation methods used include variance analysis of direct material costs, direct labor cost variances (variance one, variance two, and variance three), and factory overhead cost variance (variance one). The conceptual framework of this study focuses on production cost budgeting, production costs, variance analysis, and deviation analysis (variance analysis) of direct material costs, direct labor costs, and factory overhead costs. The results of this study indicate that the production cost budget used as a production cost control tool at PT Kalimantan Concrete Engineering has not functioned optimally, as unfavorable variances are still observed. The overall cost variance in 2022 was favorable, amounting to Rp 25,782,095,189, while the overall cost variance in 2023 was unfavorable, amounting to Rp 9,383,538,032.
