Abstract

This study aims to examine the mechanism of cell adaptation to hypertonic conditions through osmoregulation processes in various types of cells and organisms. The method used is a systematic literature review of 30 national and international journal articles sourced from Google Scholar and ScienceDirect databases. Articles were selected based on inclusion criteria that include topic suitability, availability of osmotic experimental data, and relevance to cellular responses. The results of the study indicate that cells adapt through the accumulation of compatible osmolytes such as proline, glycine betaine, and sorbitol to maintain intracellular water and ion balance. This response was observed in various objects, including Rhoeo discolor cells that showed optimal adaptation to 0.26 M sucrose with a decrease in plasmolysis from 85% to 36%, and Inpari rice seeds with an increase in drought tolerance of up to 50% through proline accumulation. Active osmoregulation was also found in frog erythrocytes, Lactobacillus plantarum, tiger prawns (543-610 mOsm/L), and tilapia which recorded an 80% survival rate at graded salinities. In general, increased osmoregulatory capacity significantly reduced cell damage from hypertonic stress, although the magnitude of the response varied among organisms. These findings have important implications for the development of rainfed agriculture, brackish water aquaculture management, and the selection of genotypes resistant to extreme climate change.

Abstract

This study aims to document and preserve the local knowledge of the people of Duwet Village, Kediri Regency, regarding the use of plants in the Ruwah Rosul tradition, which is carried out before traditional wedding ceremonies. This study uses a qualitative descriptive method with the determination of key informants (traditional leaders) through purposive sampling, followed by snowball sampling of additional informants (people who practice the tradition). Data collection was carried out through interviews, observations, and documentation, which were then validated using triangulation techniques. The data were analyzed descriptively through the stages of data reduction, data presentation, and conclusion drawing. The results of the study found 10 types of plants dominated by shrubs, with flowers being the most widely used part of the plant in each ritual arrangement. Each plant has a philosophical meaning that represents the values of prayer, hope, and harmony in life. Most species have not been evaluated for their conservation status (Not Evaluated), but conservation practices have been carried out by the community through cultivation in their yards. This study provides a new contribution by integrating aspects of ethnobotany, cultural symbolism, and local conservation into a single framework for analyzing the Ruwah Rosul tradition.

Abstract

This study aims to document and preserve local knowledge about the use of medicinal plants for skin diseases used by the community of Jeruk Purut Village, Pasuruan Regency. The research method used is a qualitative descriptive approach. Data were collected through interviews, observations, and documentation. Key informants were determined using purposive sampling, followed by snowball sampling to expand information from additional informants. The data were analyzed descriptively through data reduction, data presentation, and conclusion drawing. The results of the study identified 14 plant species from 11 families used by the community to treat skin diseases, including acne, tinea versicolor, dermatitis, scabies, and ringworm. Leaves are the most widely used part of the plant due to their secondary metabolite content, which is effective as an antibacterial, antifungal, and anti-inflammatory agent. Processing is done traditionally through pounding, boiling, cutting, grating, or heating, and applied by rubbing, sticking, compressing, or drinking. The conservation status of most species is classified as Not Evaluated, indicating limited data and the need for further research as a basis for assessing extinction risk. These findings emphasize the importance of preserving local knowledge and the need for further research to ensure the sustainable use of medicinal plants.

Abstract

This study aims to document and preserve the local knowledge of the Singosari community, Malang Regency, East Java in utilizing plants for the Tosan Aji Madakaripura tradition. A qualitative descriptive approach was used in this study, where data were collected through semi-structured interviews, observation, and documentation. Key informants were determined using a purposive sampling technique, then additional informants were selected using snowball sampling. The data obtained were then analyzed descriptively with the stages of data reduction, data presentation, and conclusion drawing. The results showed that there were 25 plant species from 19 families dominated by tree habitus with the most widely used part being the trunk for carving and extracting. Plants used in this tradition have different philosophical meanings that reflect the reasons for their use in the tradition. The conservation status of most plants is included in the category of least concern, meaning that their populations are still stable, and there are conservation efforts by the community through cultivation. The implementation of the Tosan Aji Madakaripura tradition demonstrates that various plant species are not only used practically but also possess philosophical meanings that represent the relationship between humans and nature. This finding emphasizes that traditional plant use must be balanced with conservation-based management to maintain the sustainability of biological resources.

Abstract

This study aims to document and preserve local knowledge about the use of plants in the Padhang Bulan tradition at Candi Jago, Tumpang Village, Malang Regency, East Java, including the types, habits, parts used, methods of use, philosophical meanings, and conservation efforts. The research used a qualitative descriptive approach. Data were obtained through interviews, observations, and documentation. Informants were determined using purposive sampling techniques, followed by snowball sampling. The data were analyzed descriptively through the stages of reduction, presentation, and conclusion drawing. The results showed that there were 21 plant species from 13 families, dominated by the Araceae family, with the majority being herbaceous and tree habitus. The most widely used parts of the plants were fresh flowers and leaves, each of which had philosophical meanings in the context of the ritual. Most of the plants are classified as Least Concern and are obtained through cultivation as a form of local conservation. The novelty of this study lies in the integration of ethnobotanical documentation, philosophical meanings, and plant conservation practices into a single framework of ritual analysis, which confirms the role of Padhang Bulan as a medium for the transmission of local knowledge as well as a strategy for preserving plant diversity based on culture.

Abstract

This study aims to document and preserve the local community's knowledge regarding the use of ritual plants in the Encek Festival. This study focuses on identifying the types, habits, parts used, methods of use, philosophical meanings, and conservation efforts of the plants used in the Encek Festival. This study uses a qualitative descriptive approach. Data were collected through interviews, observation, and documentation. This study involved a number of informants who were determined gradually through purposive sampling, followed by snowball sampling until data saturation was reached. The data obtained was then analyzed descriptively with reference to Miles and Huberman's analysis stages, namely data reduction, data presentation, and conclusion drawing. The results of the study show that the Encek Festival utilizes 10 plant species from 8 families, dominated by tree habitus, with flowers as the most widely used part and generally arranged in ritual processions. These plants have philosophical meanings as symbols of spirituality to God. The conservation status of most species is classified as Not Evaluated, while several others are classified as Least Concern, indicating a relatively low risk of extinction. Based on how they are obtained, the plants used come from cultivation and purchase, so their use does not directly put pressure on plant populations. This study confirms that the Encek Festival plays an important role in preserving ethnobotanical knowledge while maintaining the sustainability of local cultural values amid the dynamics of modernization.

Abstract

The Seblang Olehsari tradition in Banyuwangi is a sacred ritual of the Osing people who use various types of plants as an important part of cultural processions. This research aims to document the use of ritual plants in the Seblang Olehsari tradition and analyze plant conservation efforts and the inheritance of local knowledge between generations in the modern era. This study uses a mixed method approach. Qualitative data was collected through interviews, observations, and documentation of village heads, traditional leaders, Seblang dancers, and the people of Olehsari Village. Quantitative data was obtained through survey techniques using questionnaires on 28 respondents. Quantitative data were analyzed descriptively through intergenerational comparisons to measure the level of local knowledge and its inheritance patterns in the younger and older generations. The results of the study show that there are 33 types of plants that are used in various stages of the Seblang ritual. Quantitatively, the younger generation has a wider range of plant species recognition than the older generation, although a number of plant species are not recognized by both generations. This pattern suggests that local knowledge related to ritual plants is still passed down between generations, mainly through the role of the family as the primary source and direct observation as the dominant transmission mechanism. These findings show that the Seblang Olehsari tradition functions as a biocultural conservation mechanism that plays a role in maintaining the sustainability of the use of ritual plants, as well as supporting the preservation of biodiversity and local knowledge of the Osing people.

Abstract

The Temas Village Selamatan tradition is closely related to the use of plants in its implementation, but the lack of documentation means that the ethnobotanical knowledge contained therein has not been widely revealed. This study aims to document and preserve local community knowledge regarding the use of ritual plants used in the Temas Village Selamatan tradition in Batu City. This study focuses on identifying plant types, habits, organs used, methods of use, stages of use, philosophical meanings, and conservation efforts. The type of research used is descriptive qualitative. Data was obtained through interviews, observation, and documentation. Key informants were determined using purposive sampling, then additional informants were selected using snowball sampling based on the recommendations of key informants. The data were analyzed using descriptive statistics to reinforce the presentation of the qualitative data obtained. The results showed that the dominance of plant use in rituals was based on the philosophical meaning contained in the plants, with the conservation status of the majority of plants classified as Not Evaluated according to the IUCN. The connection between plant use and the philosophical meaning contained therein indirectly supports plant conservation for the sustainability of rituals. These findings confirm that plants play a role as living archives that must be preserved for future generations.

Abstract

The Kirab Jolen tradition is one of the local wisdom of the Javanese people that utilizes various types of plants, but the local knowledge that accompanies it has the potential to be eroded due to limited scientific documentation. This research aims to document and preserve the local knowledge of the community regarding the use of ritual plants in the Kirab Jolen Tradition. This study uses a qualitative descriptive approach by collecting data through participatory observation, in-depth interviews, and documentation. Informants were determined using purposive techniques followed by snowball sampling, involving village heads, shamans, and community leaders. The data was analyzed descriptively through the stages of data reduction, data presentation, and conclusion drawn. The results of the study identified 26 types of plants belonging to 17 families dominated by herbal habitus with the most widely used plant parts in the form of fresh fruits. The ritual plant has a philosophical meaning that is closely related to the value of spirituality and an expression of gratitude to God. Based on the IUCN conservation status, most plants are in the category not evaluated, but the community has implemented local conservation efforts through planting and care in gardens and yards. These findings show that the Kirab Jolen Tradition plays an important role in the preservation of local wisdom, the strengthening of ethnobotanical knowledge, and the sustainability of biological resources.

Abstract

The purpose of this study is to determine the diversity of fish species in the Pengga Dam. The type of research used is descriptive and exploratory. The research population is all types of fish found in the Pengga Dam, and the research sample is the type of fish caught by fishermen in the Pengga Dam. The data collection techniques in this study were carried out by observation, sampling, morphological analysis techniques based on literature reviews, documentation, and collection. The data on fish types that have been obtained are continued to calculate the diversity index using the Shannon-Wiener diversity index formula (Hʹ = -∑pi ln pi). Based on the data from the research results, a total of 381 individuals were obtained from 5 points with 3 takes, and identified in a total of 4 species (Oreochromis niloticus, Pterygoplichthys multiradiatu, Channa striata, and Barbonymus gonionotus) which belong to 2 classes (Actinopterygii and Osteichthyes), 3 orders (Peciformes, Siluformes, and Cypriniformes), 4 families (Chichlidae, Loricariidae, Channidae, and Cyprinidae), 4 genera (Oreochromis, Pterygoplichthys, Channa,  and Barbonymus). From the results of the data analysis, it can be concluded that the index of fish species diversity in the Pengga Dam with three sampling times is classified as low.
