Abstract

This study investigated the ethnobotanical use of plants as natural preservatives and colorants in food and textile applications in Blitar, Indonesia. An exploratory ethnobotanical survey using qualitative and quantitative approaches involved 30 informants through field observations, semi-structured interviews, and documentation. A total of 15 plant species belonging to 13 families were documented for food preservation, food coloration, and ecoprint dyeing. Leaves were the most frequently utilized plant parts (33.3%), followed by flowers, stems or bark, and fruits (20% each), while tuber accounted for 6.7%. Use Value (UV), calculated from informant reports, ranged from 0.13 to 0.70. Allium sativum and Pandanus amaryllifolius recorded the highest UV values (0.70), whereas Rhizophora apiculata had the lowest (0.13). The Informant Consensus Factor (ICF) was 0.94 for natural preservatives, 0.94 for food colorants, and 0.92 for ecoprint dyes, indicating substantial agreement among informants regarding plant use. Reported phytochemical compounds included eugenol, allicin, tannins, flavonoids, anthocyanins, and carotenoids, based on published literature. These findings highlight the continued relevance of local ethnobotanical knowledge and the potential of plant-based preservatives and colorants as locally adapted alternatives to synthetic additives and dyes, supporting further research into sustainable resource utilization and biodiversity conservation.

Abstract

Indonesia is recognized for its rich plant biodiversity and traditional medicinal knowledge. However, ethnobotanical documentation of plants used for fertility-related purposes remains limited in some local communities. This study aimed to identify and document medicinal plants traditionally used to support fertility by communities in Blitar, Indonesia. A descriptive ethnobotanical survey was conducted using qualitative data collection and quantitative analysis. Data were collected through field observations, semi-structured interviews, and photographic documentation across six subdistricts of Blitar Regency and City. Twelve key informants, comprising traditional birth attendants and herbal medicine practitioners (jamu makers) were recruited using snowball sampling. Qualitative data were analyzed descriptively, while quantitative data were analyzed using the Family Use Value (FUV) to assess the relative importance of plant families in traditional fertility practices. The findings documented 28 plant species belonging to 17 families. Zingiberaceae, Annonaceae, and Rutaceae were the most frequently represented families. Leaves (35.8%) and rhizomes (28.5%) were the most commonly used plant parts. Annonaceae exhibited the highest FUV (4.00), followed by Rutaceae (2.00) and Zingiberaceae (1.38), despite the latter's greater species richness. These findings highlight the continued practice of traditional fertility-related plant use in Blitar and provide baseline information for further phytochemical and pharmacological investigations.
