Abstract

The ethnobotanical utilization of medicinal plants is an integral part of the local wisdom of the Penguluh Tribe community in KPHP Limau Unit VII Hulu Sarolangun, Jambi. However, the lack of systematic documentation of key variables hampers efforts to preserve and develop this practice. This study aims to identify key variables that play a role in the sustainability of medicinal ethnobotany utilization. The methods used include primary data collection through in-depth interviews with stakeholders, literature reviews, and analysis of relationships between variables using the MICMAC (Matrix of Cross-Impact Multiplication Applied to Classification) approach. The results of the study show that of the 15 variables analyzed, seven main variables, such as regulation, types of medicinal plants, cultivation techniques, sources of knowledge, social roles, conservation efforts, and integration of local and formal learning, have a significant influence on the medicinal ethnobotany utilization system. The regulatory variable is identified as the key factor with the highest impact. The discussion highlights the importance of managing driver and linkage variables to ensure system sustainability. In conclusion, strengthening regulations, conservation of natural resources, and integrating local knowledge with scientific approaches are needed to strengthen medicinal ethnobotany and sustain local communities' welfare.

Abstract

The response of composting microbes to fly ash can show an increase or decrease in population depending on the type and concentration of fly ash used. This study aims to identify the effect of fly ash addition on the composting of citronella (Cymbopogon nardus (L.) Rendl.) leaf waste, specifically in relation to changes in the C/N ratio and the number of composting microbes, and the identification of fungal species that developed during the process. The composting treatments included citronella leaf waste without alkali (K), also with the addition of alkali in the form of 2% dolomite (D), fly ash of 2% (FA1), 5% (FA2), 10% (FA3) and 15% (FA4). The analysis used in this study was a quantitative descriptive analysis related to the analysis of C-organic and total N, as well as composting microbes. Quantitative descriptive analysis was employed to assess C-organic content, total nitrogen, and microbial populations. The results demonstrated that the incorporation of fly ash influenced both the C/N ratio and microbial abundance. The addition of 10% fly ash proved to be the most effective treatment, increasing nitrogen content and reducing the C/N ratio to 26, while supporting bacterial growth up to 3.0 × 10¹¹ CFU/g. Fungal identification revealed the presence of Rhizopus sp., Trichoderma sp., and Aspergillus sp., which contribute to the degradation of organic matter in citronella leaf waste.

Abstract

The Pengulu Tribe in Limun District, Sarolangun Regency, Jambi Province, has long used the fruit of *Scaphium macropodum*—locally known as "merpayang" or "mempayang"—as a traditional medicine. *Scaphium macropodum* belongs to the Sterculiaceae family and has a broader distribution compared to its seven subspecies. This study investigates the ecology of *S. macropodum* to provide initial information on its use by the Pengulu Tribe, as well as the population and habitat conditions in Sarolangun Jambi's production forest. The study aims to estimate the population of *S. macropodum* in the forest and analyze the ecological factors influencing its habitat. Conducted between December 2023 and January 2024, the research utilized observation, interviews, and literature review methods, with data analyzed descriptively and qualitatively. Ecological factors were examined using the Importance Value Index (INP), diversity and evenness indices, community similarity index (Ward method), and Principal Component Analysis (PCA). The study identified 47 species from 18 tree families within the *S. macropodum* habitat. The dominant species in two research sites, APL NM and HA DM, were *Shorea parviflora* (meranti). At HL DT and APL DM, the dominant species were *Shorea multiflora* (squirrel coconut) and *Canarium* sp. (mosquito legs). The Shannon-Wiener diversity analysis indicated moderate diversity and evenness across the four sites. APL NM and HA DM had significant community similarity (90.81%), while APL DM had a lower diversity index compared to the other sites.
