Abstract

The need for efficient micro-hydro power generation systems for low head locations and the challenges of electrification in remote areas are increasing. The Archimedes Screw Turbine (AST) offers a simple and environmentally friendly technological solution; however, experimental studies on single-blade configurations with heads below 1 meter are limited. This study aims to evaluate the performance of a single-blade AST turbine through experimental testing at varying heads (0.7-1.0 meters) and flow rates (106-1035 L/min). The analyzed parameters include torque, mechanical power, and turbine efficiency, with the application of the Taguchi method for optimization of experimental design and reduction of the number of tests. Results show that flow discharge has a dominant influence on turbine performance compared to head, with the maximum power of 115.89 W and the highest efficiency reaching 68.72% under the condition of 1 meter head and 1035 L/min discharge. This study confirms that the single-blade AST turbine can function optimally at low head conditions and is worthy of further development for small-scale renewable energy systems in irrigation canals and other shallow flow sources.

Abstract

The phenomenon of brain rot, associated with repetitive and fast-paced digital content, poses risks to adolescents’ literacy and critical thinking skills, thereby requiring educational interventions to raise awareness and promote healthier digital habits. This study aimed to evaluate the effectiveness of a literacy socialization program based on Participatory Action Research (PAR) combined with Focus Group Discussion (FGD) in improving adolescents’ knowledge of brain rot. The program was conducted on July 27, 2025, in collaboration with PIK-R Andongsili, involving 15 female adolescents aged 14–22 years. The intervention consisted of structured material presentation followed by group discussion using case studies and mind mapping activities. Knowledge was assessed using a pre-test and post-test design, and data were analyzed using the paired t-test after the Shapiro–Wilk normality test. The results showed a significant improvement in knowledge, with the mean score increasing from 6.60 before the intervention to 7.80 after, yielding a mean difference of 1.20 points (p = 0.004). Furthermore, the proportion of participants categorized as having good knowledge increased from 26.7% to 73.3%. These findings indicate that literacy socialization through PAR and FGD effectively enhanced adolescents’ understanding of brain rot.

Abstract

Student learning success is determined not only by the way teachers teach at school, but also by the active role of parents in supporting the learning process. This study aims to measure the impact of collaboration between parents and teachers on improving student achievement. From various articles analyzed, relevant studies published between 2020 and 2025 were selected. The results indicate that regular communication, parental involvement in school activities, and collaboration between teachers and parents in monitoring and guiding students' learning progress significantly contribute to their academic achievement. Thus, organized and structured collaboration between families and schools can increase student learning participation and improve academic and non-academic achievement. The results of this study emphasize the importance of clear communication mechanisms, parental involvement programs, and joint planning between teachers and families to optimize student learning outcomes. Some recommended practical implementations include communication training for teachers and parents, regular meeting schedules, and joint evaluation of learning strategies used.
