Abstract

This study aims to explore mathematical concepts in the local culture of Maros Regency assisted by Artificial Intelligence (AI) through collaborative project-based learning integrated with social media. The study focuses on three Bugis-Makassar traditions (Makkellu, Mappassili, Mappacci), the Dende-dende traditional game, and the Peca Sura tradition. A qualitative ethnographic approach was employed involving participatory observation, in-depth interviews with six cultural informants, photo/video documentation, and the active participation of 15 mathematics education students acting as co-researchers and project-based learners. AI technology served as a supportive analytical and visualization tool—utilizing computer vision algorithms for geometric/symmetry extraction and prompt-based analytical tools for data synthesis. The results show that Makkellu contains facial geometry, ratios, and symmetry; Mappassili is associated with cylindrical volume, circular perimeters, and arithmetic mean temperatures; Mappacci displays symmetry and permutation patterns; Dende-dende contains plane coordinates, angles, and outcome sample spaces for game strategies; while Peca Sura reflects volume, material proportions, and fractional distribution. Social media served as a supportive platform for disseminating educational content: Peca Sura's post received the highest interaction (240 likes, 46 comments, 25 shares), followed by Dende-dende and Makkellu. This research highlights that integrating AI support and social media into ethnomathematics offers a potentially beneficial and engaging pathway for contextual mathematics education and cultural preservation.

Abstract

Drylands have potential to be developed for cultivation but still require appropriate management. Cucumber is a horticultural crop classified as a fruit vegetable, which can be consumed fresh or processed into various food products. This study aimed to determine the effects of cow manure organic fertilizer and Phonska NPK fertilizer on the growth of cucumber plants. The study was conducted in Rempek Village, Gangga District, North Lombok Regency, from December 2025 to January 2026. It was arranged in a Randomized Block Design (RBD) with the following treatments: without cow manure organic fertilizer (O1), with cow manure organic fertilizer (O2), without Phonska NPK fertilizer (K1), and with Phonska NPK fertilizer (K2), resulting in four treatments, each replicated five times, for a total of 20 experimental units. The results showed that the application of cow manure organic fertilizer had a significant effect on plant height and number of leaves, whereas the application of NPK fertilizer had no significant effect on any of the observed parameters.

Abstract

Background: AI is increasingly examined as a tool for science-specific instruction, feedback, inquiry and teacher preparation, but research designs and claimed outcomes vary. Methods: This systematic literature review applied PRISMA 2020 reporting to a title-only Scopus search through Watase Uake on 5 September 2026. Two phrases retrieved 123 and 114 raw records, respectively (237 total). Searches were restricted to Q1 journal publications dated 2023–2026. The initial selection retained 49 articles; eight were removed in a subsequent science-education relevance audit. Two further Q1-indexed Scopus reports identified outside the Watase export were assessed but excluded as unrelated plant-science research. The final corpus comprised 41 articles, synthesized descriptively and thematically with study designs differentiated. Results: The literature describes AI as a scaffold for inquiry, dialogic science reasoning, multimodal representation, feedback, learning analytics and science-teacher preparation. Some primary studies report context-dependent benefits for measured learning outcomes, but findings cannot be generalized across heterogeneous designs. Conclusions: Appropriate science-specific pedagogy, human–AI interaction, teacher competence and ethical oversight are central considerations.

Abstract

This Research and Development study developed a Project-Based Learning (PjBL) electronic module on static fluid concepts for Grade XI students at SMA Negeri 3 Kota Ternate. The development was described through the analysis, design, development, implementation, and evaluation (ADDIE) stages. The module was evaluated by four expert validators and trialled with 38 students. Expert ratings yielded 78% for material feasibility and 79% for media feasibility (overall mean = 78.5%, feasible). Expert-rating reliability of the e-module was evaluated using the intraclass correlation coefficient (ICC = 0.96). The five-item learning achievement test yielded Cronbach’s alpha = 0.98. The reported student practicality mean was 3.5, while the pre-test and post-test means were 9.43 and 64.87, respectively. The normalised gain computed from class means was 0.61 (moderate). These descriptive outcomes indicate that the module met the reported feasibility criterion and that student performance improved during implementation; the single-group design does not permit causal attribution.

Abstract

The hydrogen atom spectrum is a fundamental topic in quantum physics education that demands deep conceptual understanding. This study aims to evaluate the conceptual understanding of prospective physics teachers and to map the profile of technology-mediated conceptual reasoning within the operationally delimited bounds of a deliberately restricted Technological Pedagogical Content Knowledge (TPACK) framework. The construct actually measured is technology-mediated conceptual representation and identification, the capacity to interpret and reason about physics concepts when instantiated through digital representation formats or simulations rather than the TPACK construct in its entirety. The study employed a descriptive quantitative case study design (without a qualitative strand) using total sampling across an entire third-year cohort (N = 32) at a state Islamic teacher training institution. Data were collected through a structured 20-item multiple-choice instrument covering Content Knowledge (CK), Technological Content Knowledge (TCK), and technology-mediated conceptual reasoning (labelled TPACK under the limited operationalisation adopted in this study). Responses were analysed using dichotomous Rasch modelling via Winsteps software to convert raw scores into linear logit intervals. Psychometric findings revealed a pronounced ceiling effect, with 34.4% of participants achieving perfect scores and an aggregate mean of 85%; low person reliability (0.56); and two items (14 and 20) yielding extreme measures that could not be estimated. The item difficulty hierarchy indicated that high aggregate performance masked a fragile conceptual architecture: a two-step procedural calculation item (Item 11, p = 0.633, ? = 0.13, SE = 0.38) was the most difficult item, whereas a fundamental item investigating the causal principle of radiation emission (Item 1, p = 0.733, ? = -0.38, SE = 0.41) ranked surprisingly high in difficulty. The domain radar chart displayed a near-equilateral configuration representing an artefact of the ceiling effect and low person reliability rather than a substantive profile. The study concludes that procedural fluency does not guarantee conceptual mastery.

Abstract

This study reports exploratory development and preliminary static-distance testing of a prototype using a DFRobot TF Mini LiDAR ToF Laser Range Sensor (SKU SEN0259), Arduino Uno, and a 16 × 2 LCD. The development narrative is organized with reference to the ADDIE framework (Branch, 2009). During the International PPL (Praktik Pengalaman Lapangan) program at Sangkhom Islam Wittaya School, Thailand, the presenter introduced basic motion concepts and the sensor’s operating principle, then demonstrated the prototype by pushing an object toward the sensor. Although the display was intended to show distance, velocity, elapsed time, and acceleration, only static distance readings were available for analysis. Five readings were recorded at each nominal reference distance of 100, 150, 200, 250, and 300 cm. The overall mean absolute error was 16.68 cm and the root-mean-square error was 20.80 cm. The results indicate that calibration and controlled testing are required before the device’s dynamic outputs can be validated. No standardized teacher-evaluation instrument or student learning-outcome data were available; therefore, the findings are limited to the prototype and preliminary static readings.

Abstract

This study aimed to describe noise levels in the drilling machine area, characterize noise dispersion patterns, identify workers' self-reported health complaints, and recommend appropriate noise control measures at PT. Dempo Bangun Mitra. A descriptive-analytic study with a cross-sectional design was employed. Data were obtained from direct noise measurements using a Sound Level Meter at 11 observation points located 0–100 meters from the noise source and questionnaires administered to 20 workers. Questionnaire responses were summarized descriptively to determine the frequency and percentage of reported health complaints and hearing protection use. The results showed that 9 of the 11 measurement points (81.82%) exceeded the 85 dB(A) reference limit. The highest noise level was 105.43 dB(A) at 0 meters, while the lowest was 71.63 dB(A) at 100 meters. An iso-dB(A) map showed that the highest noise concentrations occurred in the western to northwestern sections of the study area, with measured noise levels falling below 85 dB(A) at distances of approximately 90 meters and beyond. This distance represents an observation specific to the study site and should not be interpreted as a universal safety threshold. All respondents reported occasional ear discomfort, ringing in the ears, and sleep disturbances; 75% reported headaches, 60% reported difficulty concentrating, and 80% reported being disturbed by noise. Consistent use of hearing protection equipment was reported in only 55% of cases. These descriptive findings indicate the coexistence of elevated noise levels and self-reported health complaints but do not establish a causal relationship between noise exposure and these complaints. The findings support a tiered noise control strategy incorporating engineering controls, exposure duration management, worker rotation, appropriate hearing protection, regular noise monitoring, and periodic audiometric testing, formalized through a Standard Operating Procedure (SOP). The cross-sectional design limits causal interpretation, and defining an appropriate safe working zone requires further assessment of exposure duration, operational variability, and noise levels measured at representative times.

Abstract

Research has been conducted on the effect of Multi Leaf Collimator (MLC) on the dose received by the head of brain cancer patients at Sanglah Hospital, Denpasar. This analysis aims to determine the effect of using MLC on dosing to brain cancer patients using Cobalt 60 (Co-60) teletheraphy. The dose given at TPS was 200 cGy but after using MLC the dose was received because MLC protects healthy organs around the irradiation field. If the dose given is still within the range of -5 % and +7 %, it is still acceptable. The amount of radiation dose that can be reduced by using MLC in this study was 1,35 % for brain cases and 0,12 % for Glioblastoma cases.

Abstract

The increasing frequency and impact of natural disasters have highlighted the importance of effective disaster mitigation policies in reducing vulnerability and enhancing community resilience. Following the devastating 2018 Lombok earthquake, East Lombok Regency implemented various disaster mitigation initiatives to strengthen preparedness and reduce future disaster risks. This study aims to analyze the implementation of disaster mitigation policies following the 2018 earthquake in East Lombok Regency, identify the supporting and inhibiting factors affecting policy implementation, and formulate implications for strengthening disaster risk reduction efforts. The study employed a qualitative research design using a phenomenological approach. Data were collected through in-depth interviews, observations, and document analysis involving government officials, disaster management practitioners, community leaders, and local residents. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, consisting of data condensation, data display, and conclusion drawing and verification. The findings reveal that disaster mitigation policies have been implemented through disaster-resilient village programs, community preparedness training, disaster awareness campaigns, and multi-stakeholder coordination mechanisms. Government commitment, community participation, effective communication, and institutional collaboration were identified as major supporting factors, while limited resources, governance challenges, and social vulnerability remained significant barriers to implementation. The study concludes that effective disaster mitigation requires a multidimensional approach integrating community-based disaster risk reduction, institutional strengthening, risk communication, technological innovation, and evidence-based governance. Strengthening these dimensions is essential for enhancing community resilience and achieving sustainable disaster risk reduction in disaster-prone regions.
