Abstract

Conventional plastics significantly contribute to environmental pollution due to their non-biodegradable nature. Eco-friendly alternatives such as biodegradable materials are being developed to mitigate these negative impacts. This study employs a mixed-method approach with three main phases: (1) exploration and characterization of biodegradable materials based on polylactic acid (PLA) and corn starch; (2) environmental impact analysis using Life Cycle Assessment (LCA) to evaluate carbon footprint and energy consumption; and (3) consumer preference surveys through questionnaires and interviews in Bandar Lampung. The results indicate that biodegradable materials exhibit higher biodegradability and lower environmental impact than conventional plastics. LCA analysis demonstrates that these materials reduce carbon emissions and energy consumption. Despite challenges such as production costs and material durability, most consumers in Bandar Lampung prefer environmentally friendly packaging. This study provides insights into the potential implementation of biodegradable materials in Indonesia and their contribution to sustainable solutions in the packaging industry.

Abstract

The development of healthy food has grown very rapidly. Healthy food is not expensive but food that can provide good health benefits. Making fruit juice drinks from red guava can increase public interest in consuming fruit to maintain health and food security. This study aims to test the physical and sensory properties of red guava juice with the addition of cinnamon and brown sugar. This study used a Completely Randomized Design (CRD) with six treatment combinations and one control. Red guava juice, adding cinnamon and brown sugar, has a pH value ranging from 4.73-5.82 and a viscosity value ranging from 255.4 - 365.8 cps. Adding cinnamon and brown sugar affects red guava juice's pH value and viscosity. The higher the addition of cinnamon and brown sugar, the higher the pH value and viscosity. Panellists liked sample P2 with 2% cinnamon and 6% brown sugar for sensory tests.

Abstract

Gembili is a type of tuber that grows widely in Indonesia and has the potential to be developed into functional food, but its utilization has not been optimal. One of the efforts that can be made is the development of gembili as pickle, a synbiotic fermented product of gembili by a starter culture of Lactobacillus plantarum B1765, which has been known as a probiotic. This study examines the effect of fermentation duration on the growth of total lactic acid bacteria (LAB), pH value, Total Titratable Acidity (TTA), and organoleptic quality aspects.  The gembili tubers were cut into sticks and fermented for 0, 2, 4, and 6 days, using Lactobacillus plantarum B1765 starter culture at 37℃. Total LAB was calculated by total plate count (TPC), pH by pH meter, TTA by acid-base titration, and organoleptic test using untrained panellists to assess the preference level using a hedonic scale. The results showed that total LAB increased from the beginning of fermentation (2.37 x 107 CFU/mL) to 1.15 x 108 CFU/mL fermentation 4 days but decreased to 1.01 x 105 CFU/mL at the end of fermentation (6 days). The pH decreased from 6.43 ± 0.02 to 3.07 ± 0.002, and TTA increased from 0.31 ± 0.010% to 0.53 ± 0.008% at the end of fermentation (6 days). Organoleptic test results showed that fermentation time affected the preference level for color, taste, aroma, and texture. The highest preference level of the four aspects was the product with a fermentation time of 4 days with a preference level in the very like category. The results of this study indicate that the optimal time of gembili pickle fermentation is 4 days based on the total amount of LAB (> 106 CFU/mL), TTA (> 0.20%), pH (3.4-4.3) has met SNI criteria and also shows the highest preference level in color, taste, aroma, and texture. Gembili pickles can be recommended to be developed as a safe synbiotic product.

Abstract

The low involvement of students in learning is still a challenge, one of which is influenced by the lecture method, which is still dominant in the teaching and learning process. The application of technology-based learning, such as e-module-assisted cybergoth, is expected to increase students' positive responses. This study aims to analyze students' responses to the application of e-module-assisted cybergogy in science learning. This study uses a quasi-experimental method with a one-shot case study design involving 32-grade VIII-D SMPN 1 Bagor students. Data was collected through student response questionnaires and analyzed using descriptive statistics. The results showed that implementing e-module-assisted cybergogy resulted in very positive student responses, with an average response score of 99.1%. In conclusion, this approach can increase student engagement in science learning. This research implies that educators can adopt e-module-assisted cybergogy to create more interactive and innovative learning.

Abstract

Methyl orange dye is an organic pollutant often found in textile industry waste and harms the environment due to its nature, which makes it difficult to decompose naturally. One method that has attracted attention in its processing is the Photo-Fenton process, which utilizes hydroxyl radicals (•OH) as powerful degradation agents. This article summarizes recent developments in applying heterogeneous Photo-Fenton to Methyl Orange degradation, focusing on degradation efficiency, factors influencing reactions, and degradation pathways. This study discusses the influence of reaction parameters such as initial pH, H₂O₂ concentration, catalyst concentration and light intensity on the degradation rate. In addition, various types of heterogeneous catalysts, including metal oxide-based and ferrous composites, were analyzed based on their effectiveness and stability in the Photo-Fenton system. The Methyl Orange degradation pathway is proposed based on an intermediate product identified in previous studies, suggesting that the reaction proceeds through a gradual oxidation mechanism until simpler and more environmentally friendly compounds are formed. The results of this study show that the heterogeneous Photo-Fenton system provides advantages over homogeneous systems, especially in increasing degradation efficiency and prolonging the catalyst reactivity cycle. The use of heterogeneous catalysts allows for the formation of larger numbers of active species, thus accelerating the breaking of the Methyl Orange structure. In addition, further research is needed to improve the stability of the catalyst, optimize reaction conditions, and evaluate its potential application on an industrial scale. This study will be a reference for developing a more efficient and sustainable Photo-Fenton-based waste treatment method.

Abstract

21st-century learning emphasises the importance of creative thinking skills through the STEAM approach, including developing STEAM-based learning models and tools. This study aims to develop a STEAM-integrated assessment instrument to measure students' creative thinking skills, as well as to determine students’ perceptions of the assessment instrument. The research and development (R&D) method produces effective and efficient educational products through improvement, development, and evaluation. The research was conducted at SMAN 1 Jambi City and SMA Adhyaksa 1 Jambi City, involving 40 students in class XI. The instrument was developed in the form of description questions on static fluid material. The results showed that students' perception was very positive, with an average assessment of 83.15% for the category ‘Very Feasible’. Validation consists of 3 aspects, namely material, language, and evaluation aspects, which show most aspects of the instrument are in the ‘very feasible’ to ‘feasible’ category. Nine of the 11 questions tested were declared valid, while 2 needed revision. The difficulty level of the questions varied from ‘moderate’ to ‘difficult’. These findings indicate that the instrument developed is feasible for measuring students' creative thinking skills in static fluid material with the STEAM approach. The novelty of this research lies in integrating STEAM components into assessment instruments that assess concept understanding and encourage the development of students' creativity.

Abstract

Effective biology learning requires various components to enhance learning, including implementing appropriate learning models and media. This study examines the effect of the SrVER learning model assisted by augmented reality (AR) media on the biology learning outcomes of 10th-grade students at SMAN 2 Mataram. This research employs a quantitative approach using a quasi-experimental method with a non-equivalent control group design. The study population consists of 13 10th-grade classes at SMAN 2 Mataram, from which four classes were selected as the research sample using purposive sampling. Data was collected through questionnaires and student learning outcome tests. The data analysis techniques used in this study include the N-Gain statistical test and the Mann-Whitney test. The results show that the experimental class achieved an N-Gain score of 0.4 (moderate), while the control class obtained an N-Gain score of 0.2 (low). Furthermore, the Mann-Whitney test yielded an Asymp. Sig (2-tailed) value of 0.001, which is less than 0.05, indicating a significant difference between the post-test scores of the control and experimental classes. These findings confirm that implementing the SrVER learning model assisted by augmented reality media can significantly improve the biology learning outcomes of 10th-grade students.

Abstract

Student learning motivation is an important factor that influences the success of the learning process. This study aims to analyze the learning motivation of junior high school students in Surabaya City, especially in science learning, without the intervention of a particular learning model or approach. This research design uses a survey design with quantitative data collection methods. The learning motivation instrument is a learning motivation questionnaire containing 12 statements based on ARCS indicators: attention, relevance, confidence, and satisfaction. The sample of this study consisted of 88 students, 32 female students and 56 male students, and the sampling technique used was cluster sampling. The data obtained were analyzed descriptively quantitatively using a Likert scale to determine the average of each indicator of student learning motivation. The results showed that the average student learning motivation reached 71% and was classified in the high category, indicating that students have a fairly good learning motivation in science learning. Therefore, it can be concluded that this research indicates that students' overall learning motivation is on the good criteria. Unfortunately, good criteria did not occur in all indicators, where the confidence indicator showed the lowest score, so there is a need to improve the confidence aspect of students so that they are more active and confident in the learning process, such as using student-centered learning models.
