This study aims to analyze the effectiveness of applying the Index Card Match (ICM) method in improving science learning outcomes of students at Ban Eyoh School in Thailand. This study uses a quantitative experimental research design with a Quasi-Experimental Design approach. Data were collected through pretest and posttest administered before and after the implementation of the ICM method. Statistical analysis showed a significant difference between the experimental and control classes, with a sig. value of 0.001 (< 0.05). The average posttest score of the experimental (80.61) was 10.31 points higher than that of the control (70.30). This effectiveness was reinforced by the N-Gain Score of “quite effective” (56%) for ICM, while the control class was “ineffective” (39%). The effectiveness of the ICM learning model is also demonstrated by: 1) A statistically significant difference between the learning outcomes of the experimental group (ICM) and the control group (conventional), 2) A higher posttest average score for the experimental group compared to the control group, and 3) The learning effectiveness level (N-Gain Score) in the experimental class was categorized as “quite effective”, while the control class was “ineffective”. Therefore, ICM can be recommended as an alternative innovative learning model, especially in the context of science learning in a challenging

Given the significant number of injuries and fatalities in construction businesses, in this field, occupational health and safety (OSH) plays a crucial role in this area. Based on various sources, the high risk of work injuries in the building industry generally occurs due to low compliance with safety standards. Therefore, to reduce occupational risks, it is very important to build an effective OSH system. Preventive efforts include the use of personal protective equipment (PPE), ongoing safety instructions, and regular observations of workplace conditions. This research uses the ISHK Tolaram Eye Clinic construction project in Batu City as a case study to analyze OSH implementation on worker performance and factors that influence work safety. The approach used is quantitative field research, where data is collected using direct observation and distributing questionnaires to craftsmen and project foremen. It is hoped that the research results can provide strategic recommendations in improving the implementation of OSH in building construction projects. Based on its approach and scope, this research is categorized at Technology Readiness Level (TKT) level 5 because it focuses on evaluating the implementation of existing systems in the field without testing or developing new technology extensively.

This study analyzes the ethnobotanical utilization of medicinal plants in West Sumatra based on the traditional Minangkabau territorial systems (Darek, Rantau, and Pesisir) and examines its implications for contextual science education. A mixed descriptive–quantitative ethnobotanical approach was employed involving 240 key informants (105 from Darek, 90 from Rantau, and 45 from Pesisir) selected through purposive and snowball sampling. Data were collected using structured interviews, participatory observation, and species documentation. Quantitative ethnobotanical indices, including Use Value (UV) and Fidelity Level (FL), were applied. The results identified 38 medicinal plant species from 24 families. Curcuma longa (UV=0.88), Zingiber officinale (UV=0.84), and Tinospora crispa (UV=0.81) were the most culturally important species. High FL values were observed for Andrographis paniculata in fever treatment (92.1%) and Curcuma longa for digestive disorders (89.6%), indicating strong cultural reliability. The findings demonstrate that Minangkabau ethnobotanical knowledge is territorially structured, culturally transmitted, and empirically reliable. This study provides a scientific foundation for the development of ethnoscience-based science learning resources, supporting contextual learning, scientific literacy, and cultural preservation in Indonesian secondary education

This investigation evaluated spatial and temporal variations in plankton abundance and community structure to determine their effectiveness as bioindicators of water quality in coastal rice-field ecosystems of Batang Regency, Central Java. Plankton samples were collected from five sampling stations using 80 mL film vials and subsequently identified through laboratory-based taxonomic analysis. Key physicochemical factors were measured ex situ, and the analyses evaluated plankton abundance, Shannon–Wiener diversity index (H’), evenness (e), dominance (C), and saprobic index. Results demonstrated relatively low plankton abundance, with Bacillariophyceae (40%), particularly Chaetoceros sp., representing the principal taxonomic group, followed by Chlorella sp. Moderate diversity levels (H’ = 1.45–2.85), high evenness (e > 0.6), and low dominance (C < 0.5) indicated a community structure with stable ecological dynamics. Most water quality parameters conformed to Indonesian water-quality criteria, characterized by a salinity of 0.5 g/L, temperatures of 23–24 °C, and dissolved-oxygen concentrations above 4.0 mg/L. However, the saprobic index revealed light to moderate pollution at stations near settlements and downstream river segments, likely influenced by domestic wastewater, agricultural runoff, and seawater intrusion. Overall, the ecosystem remained supportive of primary productivity, emphasizing the significance of plankton as sensitive indicators for monitoring coastal agricultural environments

This study aims to analyze the sustainability of Lembah Palu variety shallot farming in Sigi Regency from economic, social, and environmental perspectives. The research involved 50 shallot farmers selected using a proportional random sampling technique. Primary data were obtained through interviews, field observations, and questionnaires, supported by secondary data from relevant institutions. The sustainability level was assessed using the Multi-Dimensional Scaling (Rapfish) approach to generate sustainability indices for each dimension. The results showed that the overall sustainability status of shallot farming was categorized as less sustainable, with an average index value of 49.37. The environmental dimension recorded the lowest index value (26.97), indicating high vulnerability due to pest and disease intensity, erosion risk, and low utilization of organic inputs. The economic dimension was categorized as fairly sustainable (64.00), as farming activities still provided financial benefits despite high production costs and limited capital access. Meanwhile, the social dimension was also fairly sustainable (57.13), reflecting contributions to household welfare, although farmer institutional strength and land tenure certainty require improvement. Strengthening environmentally friendly practices, improving cost efficiency, and empowering farmer institutions are essential to support balanced and sustainable shallot agribusiness development

Teachers in rural Islamic boarding schools (pesantren) often have limited access to digital training and few opportunities to develop innovative instructional media for Arabic language instruction. This study investigates how mobile-based training can empower Arabic language teachers to create animated learning videos and examines the types of mentoring that facilitate this process. Using a qualitative Participatory Action Research (PAR) design, the study engaged 16 teachers from three rural pesantren in iterative cycles of training, hands-on practice, reflection, and guided mentoring. Data were collected through in-depth interviews, observations, documentation of teacher-produced videos, and continuous digital communication. The findings reveal a six-phase empowerment process: initial digital literacy gaps, emerging awareness of the pedagogical potential of mobile technology, step-by-step skill acquisition through experiential practice, negotiation of technical and contextual challenges, internalization of digital competence accompanied by increased self-efficacy, and early instructional implementation of animated videos. Mentoring, characterized by personalized guidance, responsive troubleshooting, modeling of complex procedures, and sustained online support, was essential in maintaining engagement and overcoming technological barriers. Teachers reported greater confidence, stronger professional agency, and improved capacity to design context-appropriate digital media. The study accomplishes that mobile-based training supported by intensive mentoring can effectively empower teachers in resource-limited Islamic educational settings. The proposed six-phase empowerment model offers a scalable and contextually adaptable framework for teacher development initiatives in rural and underserved environments
