Abstract

The Ranggawulung Urban Forest represents a critical green open space with substantial potential for biodiversity conservation within an urban context. This study aims to characterize the vegetation community structure and assess the conservation status of recorded plant species. Vegetation inventory was conducted using a quantitative approach based on growth stages at two sites: the Urban Forest Block and the Camping Ground Area. The analyses included the Important Value Index (IVI), Shannon-Wiener diversity index (H’), Margalef spesies richness index (Dmg), and evenness index (E). The analysis of species composition and structure revealed distinct patterns in the distribution of the IVI across locations and growth stages. Swietenia mahagoni demonstrated the highest IVI at the seedling growth stage within the urban forest block, as well as at the tree growth stage within the camping ground area. In contrast, within the urban forest block, Maesopsis eminii exhibited the highest IVI at the tree growth stage. Furthermore, in the camping ground area, Cyperus rotundus attained the highest IVI at the seedling and understory vegetation strata. The Shannon-Wiener diversity index (H’) in Ranggawulung Urban Forest indicates that the seedling and understory vegetation strata exhibit higher species diversity compared to the tree strata. The highest H’ value was recorded in the seedling and understory vegetation of the camping ground area (3.5), whereas the lowest was observed in the tree stratum of the camping ground (2.83). The species richness index (Dmg) displayed a similar pattern, with the highest value found in the seedling and understory vegetation of the camping ground (10.42) and the lowest in the tree stratum of the urban forest block (5.22). Meanwhile, the evenness index (E) was relatively high across all categories, peaking in the tree stratum of the urban forest block (0.93), indicating the most balanced distribution of individuals among species in this category. Four species were classified as thteatened acording to the IUCN Red List and CITES Appendices. These findings fulfill the study objectives and underscore the ecological value of the Ranggawulung Urban Forest as a biodiversity refuge, highlighting the need for sustained conservation actions and ecologically informed urban forest management.

Abstract

Indonesia’s forest areas are rich in medicinal plant species that have been traditionally used by local communities; however, much of their potential remains undocumented and underutilized. Mount Puntang, Bandung Regency, West Java, is a mountainous forest area with high potential for medicinal plant diversity; however, scientific studies on the identification of species and the pharmacological potential of medicinal plants in this area remain limited. This study aims to identify medicinal plant species in the Mount Puntang area of Bandung Regency. The research was conducted in August 2020 utilizing a descriptive exploratory method. Primary data collection was carried out through fieldwork observations on individual plants in medicinal plant demonstration plots as well as in the home gardens of local residents surrounding the Mount Puntang forest area, supplemented by semi-structured interviews with 20 local informants. Data were analyzed quantitatively using descriptive statistics. The results showed the presence of 48 medicinal plant species from 29 families. The most dominant family was Acanthaceae, accounting for 10.42%, followed by Asteraceae, Fabaceae, Solanaceae, and Zingiberaceae, each accounting for 6.25%. The plant parts most frequently utilized were leaves (36.78%), roots (16.23%), stems (13.67%), fruits (10.26%), seeds (5.98%), flowers (5.13%), bark (4.27%), rhizomes (4.27%), and tubers (3.42%).

Abstract

The use of non-timber forest products (NTFPs) at the community level remains largely limited to the sale of low-value raw materials. One potential commodity is nutmeg produced by the Wonoharjo Forest Farmer Group (KTH Wonoharjo) in Pujo Raharjo Village, Pesawaran Regency. This community service program aimed to develop value-added nutmeg-based products to empower the economic capacity of the forest farmer group by increasing product value, enhancing technical skills, and strengthening business institutions. The program was implemented using a participatory approach, encompassing stages of site surveys and potential identification, raw material collection, initial formulation of nutmeg candy products, technical training in processing and food safety, packaging and branding training, and the preparation of Standard Operating Procedures (SOPs) for production. The results demonstrated an improvement in community skills in processing nutmeg into candy products with acceptable taste and texture, the establishment of product identity through simple packaging and labeling, and the development of SOPs as guidelines for independent production. Therefore, the development of nutmeg-based processed products can serve as an effective strategy to strengthen the economic capacity of forest farmer groups by leveraging local potential.
