Abstract

This study aims to analyze the role and strategies of introducing mathematical proofs appropriately for students, as well as to describe their contribution to enhancing logical, critical thinking, and understanding of mathematical concepts. The method used is library research with a descriptive qualitative approach through the analysis of various current scientific literature relevant to mathematics learning and education. The results of the study indicate that mathematical proofs not only function as a tool for verifying the truth of a statement but also as an epistemological process that develops deductive, argumentative, and reflective reasoning skills in understanding the structure and relationships of mathematical logic. Effective introduction strategies include the use of visual representations, collaborative learning, linguistic scaffolding, and the application of a gradual approach from informal argumentation to formal deduction. The approach has been proven to enhance students conceptual understanding, argumentative skills, and logical awareness. The implication is that proofs need to be systematically integrated into mathematics learning in secondary schools to strengthen Higher Order Thinking Skills (HOTS) and develop a scientific mindset in accordance with the principles of the Merdeka Curriculum

Abstract

Food waste generated from the household sector is one of the largest contributors to environmental degradation in Indonesia. Food waste generated from the household sector is one of the main contributors to the increasing volume of organic waste in Indonesia. This issue not only creates social and economic problems but also poses a serious threat to environmental sustainability. This study aims to analyze the contribution of household food waste to environmental degradation and to review sustainable management strategies. This study employs a Systematic Literature Review (SLR) method guided by the PRISMA 2020 Statement to review relevant national research conducted during the period 2018-2025. The results of the literature selection show that the impacts of household food waste on environmental sustainability can be categorized into three main dimensions: (1) ecological impacts, including pollution and the increase of greenhouse gas emissions; (2) resource impacts, such as the wastage of energy, water, and land; and (3) social-environmental impacts, including the increasing burden of regional waste management and the declining quality of life for communities living near landfills. The findings emphasize that the management of household food waste plays a crucial role in achieving environmental sustainability, particularly in supporting the attainment of Sustainable Development Goal (SDG) 12, which focuses on responsible consumption and production. Therefore, it is necessary to implement strategies of reduction, reuse, and recycling of food waste at the household level to minimize the negative impacts on environmental sustainability in Indonesia.

Abstract

This study aims to examine the organoleptic storage life of kecicang chili sauce using vacuum storage. The research design is experimental, involving 3 trained panelists, all of whom are lecturers from the Culinary Arts Vocational Education Study Program. The data collection method used in this study was observation through organoleptic testing using a 5-point Likert scale, namely 5) Very Good, 4) Good, 3) Fairly Good, 2) Not Very Good, 1) Very Poor. Data analysis used quantitative descriptive methods. The results of this study indicate that: 1) Processing affects the quality of kecicang chili sauce, using a technique that involves grinding the ingredients using a chopper, cooking at a temperature of ±70°C, and then vacuum packing. The organoleptic test results showed that vacuum storage was able to maintain the sensory properties of the sambal, as assessed from the aspects of colour, distinctive kecicang aroma, kecicang texture, solid dough texture, and distinctive kecicang taste, which were rated “fairly good” based on colour, aroma, texture, and taste. Vacuum-sealed sambal maintained its best quality until day 3rd, with no signs of leaking. The most significant changes occurred in the flavor and aroma, rendering it unfit for consumption. The sambal packaging, which showed no signs of leaking, maintained its sensory quality until day 5.

Abstract

Air pollution is an increasingly serious environmental issue in major cities, including Serang City. The decline in air quality due to motor vehicle emissions, industrial activities, waste incineration, and the reduction of green open spaces harms public health and the environment. Polluted air can cause respiratory problems, reduce the quality of life, and threaten urban ecosystems. This study aims to analyze the level of knowledge, perceptions, and behaviors of Serang City residents regarding air pollution, as well as assess their support for air pollution control policies. The methods used include a mixed-method approach through questionnaires, in-depth interviews, and participatory observation. The results of the study show that the community has a good understanding of the sources of air pollution, particularly vehicle and industrial emissions. They are also aware of the impact of pollution on health, especially for children and the elderly. However, the implementation of protective behaviors such as wearing masks is not yet consistent. Some positive behaviors have begun to develop, such as not burning trash and planting plants at home. Support for pollution control policies is also high. This study emphasizes the importance of continuous education, law enforcement, and collaboration between the government, society, and environmental communities in efforts to mitigate air pollution in Serang City.

Abstract

The use of virtual classrooms in the learning process is a strategic step to create a flexible learning experience, accessible anytime and anywhere. Schoology's "Plasma" as a virtual classroom platform offers various digital learning features that enable students to develop Self-Regulated Learning (SRL). Through access to materials, discussions, and other digital learning resources, students are encouraged to be more active, independent, and able to plan, monitor, and evaluate their own learning process. SRL is an important internal factor that plays a role in learning success, because it encourages students to realize their learning needs without relying on direct direction from the teacher. This study is a classroom action research conducted by mathematics teachers at SMA Negeri 1 Gedongtataan, Pesawaran, Lampung, with 30 students of grade XII IPA 1 in the 2022/2023 academic year. Data were collected through questionnaires, observations, and interviews, then analyzed using descriptive statistics. The results showed that the use of Schoology's virtual classroom significantly improved students' SRL. The comparison of the average SRL scores in Cycle I and Cycle II, 2.7 and 3.2, respectively, indicates a consistent increase. This finding confirms that the integration of Schoology's virtual classroom is effective in enhancing students' learning independence at the secondary education level.

Abstract

Zinc (Zn) is one of the most common heavy metal contaminants found in industrial wastewater and solid residues such as slag, electroplating waste, and metal ash. At excessive concentrations, Zn can cause environmental disturbances, including toxicity to aquatic organisms, disruption of microbial activity, and groundwater contamination. Long-term exposure may also lead to bioaccumulation and potential health risks to humans. This article presents a comprehensive literature review that discusses the chemical properties of Zn, its environmental behavior, and the development of recent treatment technologies within the last five years. Several techniques, including adsorption using modified or composite materials, biosorption utilizing microalgae and agricultural biomass, as well as solidification–stabilization with amendment agents such as biochar or iron-sulfide compounds, are evaluated and compared. The literature indicates that no single treatment method is universally effective for all waste types; therefore, hybrid or integrated treatment systems are considered more efficient and sustainable. Based on the reviewed evidence, this study proposes an engineering concept that emphasizes environmental safety, cost-effectiveness, and industrial applicability.

Abstract

This study aims to analyze the effect of nutrient types on kombucha fermentation using Sosro Tea as a medium. The practicum was conducted with two variations, namely honey as a natural nutrient and Tropicana Slim as a low-calorie sweetener. Parameters observed included color changes, aroma, SCOBY layer formation, pH, and microbial contamination. The results showed that fermentation using honey produced the best combination, which was characterized by a brighter color change, a stable sour aroma, the formation of a thick and pure white SCOBY, and a stable pH of around 4. In contrast, fermentation using Tropicana Slim failed to achieve optimal results. This low-calorie sweetener cannot be metabolized by microbes, resulting in a thin SCOBY and the appearance of green-black mold. Based on these results, it can be concluded that the success of kombucha fermentation is greatly influenced by the availability of simple sugars, which are the main energy source for the SCOBY. In addition, the culture's resistance to microbial contamination also plays an important role in the fermentation process.

Abstract

This study aims to model the Infant Mortality Rate (IMR) in East Nusa Tenggara Province using truncated spline nonparametric regression. In this study, IMR is associated with four predictor variables: the percentage of poor people, the percentage of pregnant women under 19 years of age, low birth weight, and life expectancy. These four variables have an unpatterned relationship, indicating the presence of a nonparametric component in the model. The truncated spline regression method was chosen because of its ability to handle nonlinear relationships between variables. The results showed that the best model was obtained using three knot points, which produced a coefficient of determination (R²) of 97.47%. This indicates that the truncated spline regression model is able to explain 97.47% of the variation in IMR in East Nusa Tenggara Province. In addition, the four predictor variables have a significant influence on the model, making a significant contribution in explaining the factors that influence IMR in the region.
