Abstract

This study aims to examine the relationship between stress levels and noise exposure among furniture workers. This study is an analytical descriptive research with a cross-sectional study design approach. The research location is at a furniture workshop in the Pahandut Seberang area of Palangka Raya. The study population consists of all workers in the furniture workshop in Pahandut Seberang and residents within a 100-meter radius of the workshop, who are considered to be at risk of noise exposure. The sample for this study was taken using a random sampling method. Data analysis was conducted using the Chi-square test, with a confidence level of 95% (p = 0.05), and the results are considered significant if p ≤ 0.05. The results showed p < 0.05, with a p-value of 0.004, indicating that there is a significant relationship between noise exposure and stress levels among workers and residents in the furniture workshop area of Pahandut Seberang. This result suggests that exposure to noise above 85 dBA may have a significant impact on stress levels in this population.

Abstract

Instant baby porridge is a popular complementary food due to its convenience. Typically made from rice flour, alternatives like Foxtail Millet (Setaria italica) offer higher levels of protein, calcium, and phosphorus. This study analyzes the organoleptic characteristics and nutritional content of instant baby porridge made from Foxtail Millet, aiming to offer a nutritious alternative to rice-based products for breastfed infants. Two formulations were tested: F1 (60% Foxtail Millet, 20% chicken, 20% corn) and F2 (60% Foxtail Millet, 20% anchovy, 20% mung bean). Organoleptic tests showed F1 to be the most preferred formulation. Nutritional analysis of F1 revealed 8.50% moisture, 3.37% ash, 14.63% protein, 2.84% fat, 71.51% carbohydrate, 62.2% digestible carbohydrates, and 9.31% crude fiber. The study found Foxtail Millet-based porridge to be a promising alternative to rice, providing better nutritional value. Furthermore, the utilization of local Foxtail Millet contributes to food diversification and strengthens local food security in Indonesia by harnessing an underutilized, nutrient-rich resource. This research highlights the potential of Foxtail Millet to support both infant nutrition and local food resilience.

Abstract

This research aims to explore the correlation between mathematical resilience and academic science emotion and provides new insights into this association through the application of canonical correlation analysis. The study involved a sample of 191 students from a state university in Central Java, Indonesia. Participants completed self-report measures to assess their levels of mathematical resilience and academic science emotion. Data was collected by randomly distributing questionnaires to students, evaluating five indicators of academic resilience (self-efficacy, planning, control, low anxiety, persistence) and three indicators of science emotions (class-related emotions, learning-related emotions, test emotions). Canonical correlation analysis was conducted to examine the multidimensional relationship between these variables and identify underlying patterns and associations. The analysis, conducted using R programming, yielded canonical correlation coefficients of 0.785, 0.396, and 0.119, indicating a significant positive linear relationship between the analyzed variables. These findings provide insight for educators and policymakers to design interventions that enhance both mathematical resilience and emotional well-being in science education

Abstract

This study aims to determine the effect of ethnoscience-based Project-Based Learning (PjBL) on students' science literacy, measure the level of improvement in students' science literacy, and analyze students' science literacy levels in terms of context, competence, and knowledge aspects. The research uses a mixed-method approach with a sequential explanatory design. The quantitative part of the study is conducted using a quasi-experiment, while the qualitative part employs field research. Data analysis techniques include the Mann-Whitney U test for quantitative data and triangulation techniques to validate data. The Miles and Huberman and Saldana model is used for qualitative data analysis.The study found that the use of ethnoscience-based PjBL significantly affects students' science literacy, with a significance value of 0.003 < 0.05. The increase in science literacy in the experimental class is categorized as high, at 0.71, while the control class shows a moderate category, at 0.60. In terms of science literacy levels, the experimental class reached a minimum of level 4, while the control class still had students at level 3. This means that students in the experimental class had better science literacy compared to the control class, particularly in terms of prospective elementary school teachers. Among the three aspects of science literacy, the competence aspect was the highest in both the experimental and control classes compared to the other aspects.

Abstract

The rapid advancement of educational technology, particularly in vocational education, has opened new opportunities to address learning challenges in complex technical subjects. This study aims to analyze the needs and design Augmented Reality (AR)-based learning media for the Digital Electronics subject using the Project-Based Learning (PjBL) model. The AR media is designed to assist students in understanding abstract and complex concepts in Digital Electronics, such as logic circuits and digital systems, in an interactive and visual manner. The research method employed is Research and Development (R&D) following the ADDIE development model, which includes the stages of analysis, design, development, implementation, and evaluation. Needs analysis results indicate that students face difficulties in understanding digital electronics concepts without additional visualization. Furthermore, both teachers and students expressed high interest in using AR technology to support a more effective and engaging learning process. PjBL-based AR media is expected to enhance students’ conceptual understanding and practical skills in Digital Electronics, as well as provide a deeper learning experience through applicative projects. By demonstrating this synergy between AR and PjBL, the study establishes a foundation for integrating immersive technologies into science and technology education, thereby enriching conceptual understanding while cultivating critical thinking, creativity, and other essential 21st-century competencies.

Abstract

This meta-analysis investigates the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' critical thinking and problem-solving skills in science education. A total of 42 peer-reviewed articles published between 2020 and 2024 were analyzed, covering diverse educational levels and scientific disciplines. The analysis revealed a large average effect size (ES = 0.798; 95% CI: 0.782–0.813), indicating a strong positive impact of PBL. The low standard error (SE = 0.043–0.060) reflects high estimation precision. Statistical tests, including funnel plot symmetry, Trim-and-Fill analysis (p = 0.991), and Egger’s regression test (p = 0.947), confirm the absence of significant publication bias. Moreover, residual heterogeneity was minimal (τ² = 0.000), validating the appropriateness of the fixed-effects model. These findings provide robust empirical evidence that PBL is consistently effective across various contexts in improving students’ 21st-century competencies. The study offers meaningful implications for educators and policymakers in designing science learning strategies that foster higher-order thinking skills.

Abstract

Flavonoids are polyphenolic secondary metabolites with various biological activities, including antioxidant and anti-inflammatory effects. This study aimed to determine the total flavonoid content in Tinospora crispa (brotowali) stem extract using the AlCl₃ colorimetric method and UV-Vis spectrophotometry. The brotowali stems were extracted using a decoction method with distilled water as the solvent. The formation of a yellow complex between flavonoids and AlCl₃ was measured at a wavelength of 435 nm using a UV-Vis spectrophotometer. A standard calibration curve was prepared using quercetin as the reference compound. The absorbance values of the sample were compared against the quercetin standard curve to determine the flavonoid concentration, expressed as mg quercetin equivalent (QE) per 100 g of extract. The total flavonoid content in the brotowali extract was found to be approximately 0.40%, indicating a moderate level of flavonoids relative to similar medicinal plants. These results suggest that Tinospora crispa stems may serve as a potential source of natural flavonoids with therapeutic applications.

Abstract

Ant diversity (Formicede) plays an important role in the ecosystem, especially as an environmental indicator. This study aims to identify the diversity of ant species in the Bumi Camping area, Malang Regency, East Java, and to evaluate the factors that influence it. Ants have evolved into insects that are easily found in terrestrial ecosystems. Of the total number of insect species in the world, approximately 12.000 of them are ants, most of which are spread across tropical areas Data collection was carried out at six points around the musholla area using two trap methods, namely bait traps and fill traps. The ants caught were collected and identified using a stereo microscope, determination keys, and supporting applications. The study found 9 different ant species, including Paratrechina longicornis. Camponatus atriceps, and Monomorium pharaonis. The diversity of ant species is influenced by environmental factors such as altitude, humidity, and food availability. The results showed that the study area had a low diversity index value, possibly due to antibiotic factors and land conversion. This study contributes to the understanding of ant diversity in tropical areas and the importance of ant habitat conservation in forest ecosystems.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the high-value aquaculture commodities in the global market, known for its excellent adaptability to various environmental conditions, rapid growth, and high survival rates. This study aims to compare water conditions and the growth performance of vannamei shrimp under three different pond management systems: supra-intensive, intensive, and traditional. The analysis was conducted by measuring water quality parameters such as temperature, salinity, pH, dissolved oxygen, ammonia, and nitrate concentrations. Growth performance was evaluated through observations of Average Daily Gain (ADG) and Mean Body Weight (MBW). At 50 days of cultivation, the supraintensive system produced an average body weight of 11.85 grams with a daily growth rate of 0.2219 grams/shrimp/day. The intensive system resulted in slightly lower growth, with an average body weight of 8.6 grams and a daily growth rate of 0.1547 grams/shrimp/day. The traditional system showed the lowest growth performance, with an average weight of 6.66 grams and an ADG of 0.0265 grams/shrimp/day. The different pond management systems influence the dynamic risks of water quality changes based on input loads from feed waste and feces. The traditional system exhibits a slower rate of water quality changes compared to the intensive and supraintensive systems.
