Abstract

This research is an ethnobotanical study of the traditional food Wa'ai Zamu, a form of cultural heritage of the Ende people, East Nusa Tenggara. The objective was to document local knowledge regarding the use of plants in making Wa'ai Zamu and the cultural values it embodies. The study employed a qualitative approach with ethnographic methods. Data were obtained through in-depth interviews with 10 key informants selected purposively, consisting of traditional leaders, women traditional food processors, and local cultural experts. Triangulation techniques were used through participant observation and literature review to strengthen the validity of the data. The results indicate that Wa'ai Zamu uses various types of local plants with nutritional value and symbolic functions in traditional rituals. Information regarding nutritional content comes from informants and is partially supported by previous literature references. This study demonstrates that traditional foods serve not only as daily consumption but also represent the identity and cultural continuity of the Ende people. Documenting this knowledge is crucial for preserving intangible cultural heritage, which is vulnerable to modernization.

Abstract

This study aims to examine the ethnoscientific values contained in the process of making traditional Lomak food from the Manggarai area, East Nusa Tenggara. Lomak is one of the culinary heritage that not only has a distinctive taste, but also reflects the local knowledge of the Manggarai people, starting from the selection of ingredients, processing techniques, to food preservation efforts. This study uses a qualitative approach with data collection techniques in the form of observation, in-depth interviews, and documentation studies. The results of the study show that the process of making Lomak contains scientific principles, such as natural fermentation techniques, sustainable use of local ingredients, and traditional knowledge about sanitation and food conservation. This ethnoscience study is expected to be a source of contextual learning in science education while contributing to the preservation of local culture. The novelty of this research lies in the application of food innovation that combines aspects of business management, marketing strategy, and cultural preservation, so that it has the potential to increase the income of Lomak artisans in the Manggarai area.

Abstract

Fermentation is an important process in the processing of traditional food of the Lio tribe, one of which is uwi kaju lamu. This study aims to examine the potential of kesi leaves (Lannea coromandelica) as a natural fermentation agent in the traditional food uwi kaju lamu, a typical food of the Lio Tribe in Ende Regency, East Nusa Tenggara. The research method used is a mix method with a sequential exploratory design (qualitative and quantitative). The qualitative method (interviews, observations, and FGD) aims to confirm the traditional knowledge of the community regarding the use of kesi leaves in the fermentation process of uwi kaju lamu, while the quantitative method is tested in the laboratory. The results showed that the cyanide level of 6 mg/kg was far below the maximum threshold of 50 mg/kg, making it safe for consumption. Secondary metabolite compounds were detected only saponins, while other compounds were not detected indicating degradation of complex components. A pH value of 9.18 (alkaline) indicates contamination in the traditional fermentation process, so further research is needed. Organoleptic tests on 30 untrained panelists showed that the taste aspect showed a high acceptance rate (of 7.47) from an average preference above 7.00 on a scale of 5-9. Overall, kesi leaves have the potential as a natural fermentation agent in the processing of uwi kaju lamu.

Abstract

The cell membrane is a semipermeable structure that regulates substance exchange between intracellular and extracellular environments, maintains cellular homeostasis, and supports metabolic processes, yet the fundamental mechanisms of diffusion, osmosis, and active transport are still frequently misunderstood in both theoretical and educational contexts. This study aims to comprehensively review substance transport mechanisms across the cell membrane and their relevance to biology education and contemporary cellular research. This research employed a narrative literature review, analyzing scientific books and peer-reviewed journal articles published within the last five to ten years, selected from databases such as Google Scholar, PubMed, and MDPI based on topic relevance. The results indicate that diffusion facilitates molecular movement along concentration gradients either directly or through transport proteins; osmosis regulates water balance through semipermeable membranes mediated by aquaporins; and active transport enables the movement of ions and molecules against concentration gradients through ATP-dependent pumps, secondary transporters, ABC transporters, and V-ATPase. These mechanisms are interconnected and influenced by membrane composition, molecular characteristics, and transporter–substrate interactions. This review highlights the importance of an integrative understanding of membrane transport processes to strengthen conceptual learning in biology education and to support advancements in cellular and biomedical research.

Abstract

Environmental stress is an external factor that affects the strength and function of plant cells, such as salt levels, extreme temperatures, heavy metals, and radiation. This can cause significant changes at the molecular level, including cell structure and chemical processes within plants. This article is a systematic summary of 30 scientific studies published in the last ten years, aiming to identify common patterns in how plant cells respond to non-living stressors. Studies have shown that environmental stressors can lead to the accumulation of free radicals (ROS). This can damage membranes, cause lipid oxidation, damage chloroplasts, and disrupt the activity of enzymes essential for photosynthesis and respiration. At the molecular level, adaptive responses occur by activating hormone signaling pathways, particularly abscisic acid (ABA) and ethylene. This also involves increased expression of genes related to water regulation and protection from oxidation, as well as activation of autophagy, a mechanism that destroys damaged cell parts. Changes in cellular components such as the vacuole, mitochondria, and cell wall indicate how cells work to maintain salt balance and basic body processes. This summary of various studies shows that environmental stress can cause complex problems, such as disruptions in metabolic processes, instability of internal organs, and changes in gene expression. Therefore, understanding how plant cells work and their structure is crucial for developing plant varieties that are resilient to climate change stress.

Abstract

Mitochondria play a central role in cellular energy production through oxidative phosphorylation that generates ATP, while also regulating metabolism, organelle dynamics, and bioenergetic signal integration. This study aims to synthesize the role of mitochondria in cellular bioenergetics through a qualitative meta-analysis of scientific articles published between 2015 and 2025. The PRISMA approach was applied for systematic article selection, resulting in 30 relevant articles analyzed for key findings. The synthesis shows that mitochondria do not operate in isolation but form a functional network that adjusts ATP production according to the specific energy demands of the cell. Mitochondrial fusion-fission dynamics influence energy distribution efficiency, while metabolic regulation and interactions with other organelles maintain cellular energy homeostasis. Mitochondrial dysfunction is associated with neuromuscular disorders, aging, and degenerative diseases including cancer. The study concludes that mitochondria are adaptive bioenergetic centers, playing a crucial role in maintaining energy efficiency and providing a scientific basis for further research in cellular biology, biomedicine, and energy-based therapeutic applications. This synthesis expands understanding of mitochondrial bioenergetic mechanisms and their implications for health and biotechnology applications.
