The Impact of Language of Instruction on Teachers' Learning Practices in Primary Schools and Secondary Schools in Dili, Timor-Leste, and Its Implications in Preparing Human Resources
Full text linkThis study analyzes the impact of using Portuguese and Tetun as languages of instruction in primary and secondary schools in Dili, Timor Leste, and its implications for human resource development. While Tetun facilitates students' understanding in local contexts, its limited global relevance presents a challenge. Conversely, Portuguese, though internationally recognized, is not fluently spoken by most teachers and students, reducing the effectiveness of the teaching and learning process. This qualitative research involved 68 informants, including education officials, principals, teachers, and students across Dili. Data were collected through interviews, observations, and documentation. The findings reveal that language barriers, particularly in Portuguese, negatively affect classroom interaction, leading to poor student comprehension and low academic achievement. This situation may hinder the development of quality human resources capable of competing globally. The study recommends that the Timor Leste government and Ministry of Education intensify Portuguese training for both teachers and students, allocate funds for Tetun development, offer incentives to high-performing teachers, and encourage the consistent use of the instructional Language at home and in school, drawing from practices in Cuba and Venezuela. Strengthening language proficiency among educators and learners is essential to improving education quality and supporting Timor-Leste's broader socio-economic advancement

Pengawet Alami Kayu Sengon dengan Ekstrak Umbi Gadung terhadap Rayap Kayu Kering: Natural Preservatives of Sengon Wood with Umbi Gadung Extract Against Drywood Termites
Full text linkABSTRACT
Sengon wood (A. chinensis) is a type of wood that has great potential as a source of industrial raw materials and holds significant economic value. However, sengon wood has low natural durability, classified as durability class IV–V, making it highly susceptible to attack by wood-destroying organisms such as termites. Therefore, wood preservation treatment is necessary to extend its service life. This study aims to analyze the interaction effect between the concentration of gadung tuber (D. hispida) extract with ethanol solvent and the soaking duration on the durability of sengon wood using the cold soaking method. The extract concentrations used were 1%, 3%, and 5%, and the soaking durations were 1 day, 2 days, and 3 days. The preserved samples were subjected to forced feeding tests using 50 healthy and active drywood termites (C. cynocephalus Light) on test specimens measuring 2.5 cm × 2.5 cm × 2 cm. The preservative performance parameters included absorption and retention, while the wood durability parameters included weight loss and termite mortality rate. The interaction between gadung tuber extract concentration and soaking duration significantly affected the retention and absorption values, while weight loss and termite mortality showed no significant effect. The highest retention and absorption values were obtained at a soaking duration of 3 days and a concentration of 5%, with average retention and absorption values of 0.028 g/cm³ and 0.438 g/cm³, respectively

Full text linkThis research aims to determine whether learning with the peer tutor model effectively improves student learning outcomes in social studies at Adabiah Padang Junior High School. This research uses a quantitative design. The research subjects were grade VIII students at Adabiah Padang Junior High School, which had 80 students. Data were collected using direct observation methods, observation sheets, and in the form of test questions. The collected data was analyzed using descriptive analysis, and the average score and the percentage completeness of student learning outcomes were calculated. Based on the research results, the value of learning outcomes and student completeness has increased. The post-test results in the three classes show an increase in the average of the three classes and the number of students or the percentage of complete students. Only a few students did not reach the minimum completeness after implementing the peer tutor learning model. Peer tutoring on student learning outcomes is practical enough for social studies learning.
Analyzing the factors affecting reading literacy skills: The case of internal and external factors
Full text linkThis research aimed to explain, analyze, and interpret the factors affecting the reading literacy skills of the fifth-grade students. This research used a mixed methods study. Data collection was carried out by direct observations, interviews, and minimum competency tests. In addition, the data analysis methods used in this research were data reduction, data presentation, and verification/conclusion. The results showed that reading literacy was influenced by internal factors (low intelligence ability, low interest in learning, and low learning motivation) and external factors (lack of parental attention, influence of TV and cell phones, influence of playmates, lack of teacher ability, and limited facilities and infrastructure). Efforts that can be made to overcome students' low reading literacy skills include providing motivation, literacy activities, increasing teacher abilities, exceptional guidance, collaboration with parents, and utilization of infrastructure
The effectiveness of the ecopreneurship model in increasing environmental awareness among college students
Full text linkThis research aims to determine the effectiveness of the ecopreneurship model in increasing environmental awareness among midwifery students. The research method was quasi-experimental, with a control group design using midwifery students as research subjects. The research stages include applying the ecopreneurship model in the learning process in the lecture hall, as well as measuring the level of knowledge before and after. A valid and reliable survey instrument was used to collect data regarding student perceptions and attitudes towards the environment. The data analysis results show that applying the ecopreneurship model significantly increases environmental knowledge and awareness among midwifery students. Previously, students tended to have a limited understanding of environmental issues and their relevance in the context of entrepreneurship education. However, after learning about the ecopreneurship model, there was a real increase in students' understanding, attitudes, and involvement towards environmental issues
An analysis of relative clauses in scientific sentences
Full text linkThis research examines the application of restrictive and non-restrictive relative clauses in academic journal articles, focusing on their syntactic and functional significance within linguistic discourse. This study utilizes data from the research titled “Verbal Humor in Selected Indonesian Stand-Up Comedians’ Discourse: Semantic Analysis.” The research uses GVTH to identify and classify relative sentences, examining their contributions to semantic clarity and literary sophistication. Restrictive clauses offer precise definitions essential for academic specificity, but non-restrictive clauses supply additional details that enhance the text. The findings underscore non-native English speakers' difficulties regarding relative clauses, shaped by grammatical disparities between their original language and English. This research emphasizes the necessity of learning relative clause usage to fulfill the requirements of high-quality academic writing. The study presents instructional implications to improve Indonesian graduate students’ and teachers’ academic writing abilities, who face mounting pressure to publish in foreign publications. Subsequent studies may build upon these findings by examining relative clause utilization across a wider corpus of academic literature and fields
School principal’s strategy in managing a child-friendly school: Bullying cases
Full text linkThis research aimed to analyze the effect of the principal's strategy in the Child-Friendly School Program (SRA) on bullying cases. This research used a quantitative approach with a population of 411 students and a sample of 80 students. Data were collected through questionnaires and analyzed using instrument tests, partial tests, normality tests, and hypothesis tests. The research framework was based on George Edward III's theory for variable X (principal's strategy in SRA) and Migliaccio and Raskauskas' theory for variable Y (bullying cases). The results showed that the school principal's strategy in the SRA Program had an influence of 20.2% on bullying cases, while other factors outside this research influenced the remaining 78.9%. In conclusion, although the principal's strategy in the SRA program contributes to reducing bullying cases, other factors also influence it. This research underlines the importance of the school principal's role in creating a safe and supportive school environment for students' development
