Abstract

Sorghum (Sorghum bicolor (L.) Moench) is a resilient cereal crop with high potential as a source of food, feed, and bioenergy. This study investigates the effect of applying rice husk biochar and liquid organic fertilizer (POC) from cow urine on the sugar and fiber content of sorghum seeds. The experiment was conducted in two phases: field trials using a randomized block design with nine treatment combinations (3 biochar doses × 3 POC doses) and laboratory analysis of sugar and fiber contents. Results show that the application of 4 t/ha biochar and 750 ml/L cow urine POC produced the highest yield in terms of seed weight per plot (0.36 t/ha) and total production. However, the highest sugar content (63.32%) was obtained in the control biochar treatment with 250 ml/L POC, suggesting that lower POC doses are more effective in enhancing sugar concentration. Fiber content showed no statistically significant differences among treatments, although a tendency for increased fiber was observed at moderate POC doses. These findings highlight the potential of using rice husk biochar and cow urine POC to improve sorghum productivity and nutritional quality while supporting sustainable and organic agricultural practices.

Abstract

The inquiry learning model certainly has shortcomings in its implementation, one of which is controlling student activities and success. This model is difficult to observe students who are not participating in groups doing experimental activities. This causes uneven delivery of material for students individually. Therefore, it is necessary for this learning model to be synergized with a participatory approach. One approach that can be used is the Participatory Ergonomics Approach. This study aims to determine whether there is a difference in the effect of the synergy of participatory ergonomics with guided inquiry learning models with conventional learning on junior high school students' eye fatigue, to determine whether there is a difference in the effect of the synergy of participatory ergonomics with guided inquiry learning models with conventional learning on junior high school students' boredom in learning, to determine whether there is a difference in the effect of the synergy of participatory ergonomics with guided inquiry learning models with conventional learning on junior high school students' science learning outcomes, and to determine whether there is a difference in boredom, fatigue and science learning outcomes of students who are taught using the participatory ergonomics approach with guided inquiry models with conventional learning for junior high school students. This type of research is a quasi-experimental researchs. This study uses a quantitative approach. The design of this study uses the Nonequivalent Pretest Posttest Control Group Design. The data in this study are in the form of learning interest questionnaire scores and learning outcome test scores which are analyzed using the MANOVA test. The results of this study indicate that: a significant value of 0.000 (p <0.05) was obtained, a significant value of 0.000 (p <0.05) was obtained, a significant value of 0.000 (p <0.05) was obtained.

Abstract

This study aimed to evaluate the effect of rice bran oil (RBO) supplementation on the physicochemical properties, microstructure, and oxidative stability of chicken-based meat emulsion products. RBO is rich in natural antioxidants such as γ-oryzanol and tocopherols, which may enhance product quality. A Completely Randomized Design (CRD) was used with four treatments (0%, 6%, 8%, and 10% RBO) and six replications. Parameters measured included pH, peroxide value (PV), color values (L*, a*, b*), microstructure (SEM), moisture, ash, fat, protein, carbohydrate, water activity (Aw), free fatty acids (FFA), and total acidity. The addition of RBO significantly (P<0.01) reduced PV, FFA, and total acidity, indicating improved oxidative stability. It also enhanced protein content, microstructural integrity, and textural properties. Although total fat content increased, the proportion of unsaturated fatty acids improved the lipid profile. Reduction in water activity suggested enhanced shelf stability. These findings demonstrate that Adding 10% rice bran oil (RBO) to chicken meat emulsions improved emulsion stability, reduced lipid oxidation and free fatty acids, enhanced protein retention, and improved microstructure.

Abstract

This study investigated breastfeeding self-efficacy (BSE) among mothers attending the Dahlia Health Center in Makassar City, Indonesia, where exclusive breastfeeding rates were reported at 73.97% in 2023. Guided by Bandura’s theory of self-efficacy, a cross-sectional design was employed to simultaneously assess various factors influencing BSE. The targeted participants included 38 breastfeeding mothers, selected based on specific criteria. Data were collected through structured questionnaires, focusing on mothers’ confidence levels regarding breastfeeding. Trained enumerators conducted direct interviews ensuring informed consent. Statistical analysis, utilizing methods such as linear regression and correlation, revealed that 76.3% of respondents exhibited good BSE. Significant relationships were identified between key factors: breastfeeding experience (p = 0.043), observation of others (p = 0.000), and verbal persuasion (p = 0.01). Additionally, the mother's physical and emotional health also significantly influenced BSE (p = 0.00). The findings highlight the importance of positive experiences, social support, and maternal health in enhancing confidence in breastfeeding. Recommendations include developing training programs for health workers aimed at providing emotional support and involving family members in delivering consistent verbal encouragement to breastfeeding mothers. This approach may improve BSE and ultimately increase exclusive breastfeeding rates in the region.

Abstract

Tofu also has a weakness, namely its high water content, so it is easily damaged because it is easily overgrown by microbes. Preservatives added are not limited to preservatives that are allowed, but many businessmen are naughty by adding formalin. White tofu is one that is circulating in the market. At room temperature the yower storage knows an average of 1-2 days. Efforts to preserve tofu by means of steaming and storing in a refrigerator can only preserve tofu for 1 day. This causes traders to commit fraud, one of which is preserving tofu so that it is durable, one of which is the addition of chemicals. According to the Food and Drug Supervisory Agency (BPOM). The treatment research method with the application of chitosan as an edible coating on white tofu is carried out in four stages, namely the preparation stage, immersion stage, storage stage, and testing stage. The preparation stage is carried nut by preparing all the materials and tools that will be used in the immersion, storage and testing stages. The immersion stage was done by soaking white tofu with concentrations varying of 0.5%  The results of the long storage test for tofu coated with chitosan showed that the tofu soaked with chitosan solution with the addition 0.01 %.

Abstract

This study explores the integration of the Argument-Driven Inquiry (ADI) model with a STEM (Science, Technology, Engineering, and Mathematics) approach in interactive e-worksheets to enhance students' scientific argumentation in food biotechnology education. Using a quasi-experimental pretest-posttest design, 60 ninth-grade students from SMPN 1 Tanjung Bintang were assigned to either an experimental group, using ADI-STEM e-worksheets, or a control group, using conventional printed worksheets. Data were collected through a validated open-ended test assessing scientific argumentation components: claims, data, warrants, and backing. Analysis of N-Gain scores, t-tests, and effect sizes indicated that the experimental group showed significantly greater improvement across all indicators, with a large effect size demonstrating substantial impact. The integration of ADI and STEM not only fostered deeper cognitive engagement but also improved students' ability to form structured, evidence-backed arguments. These findings highlight the potential of combining inquiry-based learning with interdisciplinary STEM content in digital formats to enhance higher-order thinking and scientific reasoning. The study contributes to 21st-century science education and calls for further research on its long-term and broader effects.

The data collection method was carried out by purposive sampling using a plot of 1x1 m2 with 10 plots per transect. Sampling was carried out at three stations, namely Station I on Pasir Putih with a medium fine sand substrate, Station II at Anoi Itam with a gravel sand substrate, and Station III on Rubiah Island with a fine sandy clay substrate. Data were analyzed using the Importance Value Index (IVI) and the Shannon-Wiener Diversity Index. The environmental parameters at each station that were measured were substrate particles, temperature, brightness, depth, and current velocity, while the chemical parameters were salinity, pH, COD, phosphate, and nitrate. The results of the study found 2615 macroalgae individuals consisting of three divisions. Chlorophyta division consists of 9 species, Rhodophyta was 7 species, and Phaeophyta was 1 species (Dyctyota dichotoma). The highest Important Value Index at each research station consisted of the Chlorophyta division with two species, namely Dictyosphaeria cavernosa (IVI = 59.18) and Halimeda opuntia (IVI = 54.15). The value of the diversity index (H') of macroalgae in Sabang waters is moderate, namely in Pasir Putih as much as 2.18, Anoi Itam and Rubiah Island as much as 2.01, and 1.97, respectively. The study concluded that the macroalgae community structure in Sabang waters exhibits moderate species diversity, with the Chlorophyta division, particularly Dictyosphaeria cavernosa and Halimeda opuntia, showing the highest importance value indices across different substrates.
