Accidents in school environments can occur unexpectedly and require quick and appropriate first aid response. This study aimed to evaluate the effectiveness of simulation-based health education in improving knowledge and first aid skills among adolescents in secondary school. Methods:A quasi-experimental study was conducted with 33 students from class XII SMA Negeri 9 Pekanbaru. Intervention consisted of interactive lectures, demonstrations, and practical simulations on various types of accidents (bleeding wounds, burns, nosebleeds, fainting, and choking). Knowledge was assessed using pretest and posttest, while skills were evaluated through observation during practical sessions. Results: Significant increase in knowledge scores from pretest to posttest. Observationally, students demonstrated improved confidence and competence in recognizing accidents, applying safety principles, and delivering appropriate first aid techniques.Simulation-based health education is effective in improving knowledge and skills related to first aid among secondary school students. Should be implemented as a routine component of school health programs and can serve as a model for replication in other schools.

Abstract This study employs the MaxEnt species distribution model (SDM) to predict the potential habitat distribution of Vatiga illudens , a newly emerging pest threatening cassava production in Indonesia. The model identifies key environmental factors influencing the species' spread, such as precipitation during the coldest quarter (BIO19), contributing 66.2%, and temperature during the wettest quarter (BIO8), contributing 18.3%. The results show that high habitat suitability zones, with a probability ranging from 0.60 to 0.99, are concentrated in southern Indonesia, particularly in Java, Bali, and Nusa Tenggara, which account for 73.33% to 56.74% of the highest suitability classes. In contrast, regions such as Sumatra, Kalimantan, and Sulawesi show suitability values below 0.30, indicating low habitat suitability. The model’s accuracy, with an average AUC of 0.925 (± 0.021), demonstrates excellent discriminatory ability. The findings support a risk-based management approach, focusing on routine monitoring in high-risk areas and strengthening biosecurity measures. This study underscores the need to integrate climate forecasting with pest management strategies to mitigate the impact of pest invasions and safeguard Indonesia's food security in the face of climate change.

A marriage agreement, or huwelijksche voorwaarden, is a legal instrument recognized under Article 29 of Law No. 1 of 1974 concerning Marriage and reinforced by the Constitutional Court Decision Number 69/PUU-XIII/2015. This agreement serves to regulate the separation of assets between husband and wife while at the same time providing legal certainty for the parties involved. However, in practice, marriage agreements often raise legal issues, particularly regarding their consequences for joint property as well as individual property. This study aims to analyze the legal consequences of marriage agreements through a case study of Pekanbaru District Court Decision No. 68/PDT/G/2009/PN.PBR Jo No. 62/PDT.G/2015/PN.PBR, in connection with the principle of legal certainty. The research method applied is normative juridical, employing statutory, doctrinal, and case study approaches. The findings reveal that although marriage agreements are legally valid, their implementation continues to face challenges, especially in relation to the enforcement of legal certainty. This study emphasizes the necessity for harmonization of legal norms and consistency in judicial decisions in order to ensure that marriage agreements have binding legal force in protecting the interests of the parties.

Tropical peatlands are critical ecosystems that provide habitat for biodiversity and store large amounts of carbon, yet they are increasingly degraded due to land-use conversion, drainage, and recurrent fires. This study examined vegetation structure and species composition along a canal-distance gradient (10-350 m across three peatland land-use types: rubber plantation, secondary forest, and burned peatland. Vegetation surveys were conducted using 40 nested plots covering four growth strata (trees, poles, saplings/shrubs, and seedlings/herbs). Community structure was analyzed using the Importance Value Index (IVI), Shannon–Wiener diversity index (H′), Margalef’s richness index (DMg), Pielou’s evenness index (E), and Simpson’s dominance index (C). Differences in environmental parameters among land-use types were tested using one-way ANOVA (p<0.05). Secondary forests exhibited the highest species richness and diversity with balanced structural complexity, whereas rubber plantations showed simplified communities dominated by Hevea brasiliensis. Burned peatlands were characterized by pioneer tree species and dense fern understorey, indicating successional arrest. Secondary forests had higher biodiversity than rubber plantations, which in turn had higher biodiversity than burned peatlands. These findings highlight that land-use intensity, canal proximity, and fire history jointly regulate vegetation dynamics in tropical peatlands and highlight the importance of forest conservation, plantation diversification, and restoration through rewetting and enrichment planting.

Abstract This study investigates the crashworthiness performance of novel crash box geometries inspired by the structural configuration of coconut tree trunks. Six models were analyzed, comprising four bio-inspired designs with square and circular cross-sections in single- and double-shell forms, along with two conventional hollow configurations. Numerical impact simulations, validated against experimental data, were conducted to evaluate force–time, force– displacement, and energy absorption responses. Results indicate that the introduction of internal reinforcement significantly enhances energy absorption, while circular geometries provide lower peak forces and more stable deformation. The findings highlight the potential of bio-inspired crash boxes for improved passenger vehicle safety.

Research aims: This study examines the impact of Basel III prudential ratios (Tier 1 capital ratio, Liquidity Coverage Ratio proxy, and Net Stable Funding Ratio proxy) on bank profitability in Indonesia, as well as the moderating role of macroeconomic factors (GDP growth and inflation).Design/Methodology/Approach: The study utilizes panel data from 63 Indonesian commercial banks over the period 2011–2022. A bank fixed effects regression model with robust standard errors clustered at the bank level is employed. Four progressive specifications are tested to assess the direct effects of prudential ratios, bank-specific controls, macroeconomic variables, and their interactions.Research findings: The Tier 1 capital ratio consistently exerts a positive and significant effect on Return on Assets (ROA), indicating that higher capital adequacy supports profitability. Liquidity proxies have a limited direct impact, consistent with evidence that the NSFR often serves as a non-binding constraint in Indonesia. Macroeconomic factors play a moderating role, with GDP growth attenuating the capital-profitability relationship and inflation reinforcing it. Robustness checks excluding the NSFR proxy or the COVID-19 period confirm the stability of these results.Theoretical contribution/Originality: This study extends the Basel III literature by demonstrating that regulatory effects on bank profitability are conditional on macroeconomic conditions in an emerging market context. It provides evidence of asymmetric moderation, where growth cycles may encourage risk-shifting while inflation enhances capital benefits.Practitioner/Policy implication: Regulators should prioritize capital adequacy enforcement while calibrating liquidity requirements to avoid undue profitability costs. Banks can optimize performance by maintaining flexible capital buffers in response to macroeconomic fluctuations. Policymakers may consider countercyclical adjustments to enhance resilience without compromising earnings.
