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

Mangrove forests are important for storing carbon dioxide (CO2) and reducing the effects of climate change. Indonesia possesses 20% of the global mangrove cover, which substantially impacts global climate mitigation efforts. However, understanding of the diversity of plant species in mangrove forests remains limited, as evidenced by the high rate of conversion of mangrove areas into aquaculture ponds, resulting in mangrove degradation. Our research in Pantai Mekar Village was conducted to augment information on mangrove plant species diversity in Indonesia, specifically in Bekasi Regency. Mangrove vegetation data were collected in Pantai Mekar Village, Muara Gembong, Bekasi from 8 to 12 July 2019. Data were collected using 2x2 m (seedlings and understory), 5x5 m (saplings), and 10x10 m (trees) plots. Importance value index (INP), Shannon-Wiener species diversity, evenness, richness, and carbon stock estimation were utilized to analyze the data. The study documented 21 species from 15 families. Species from the Acanthaceae family were predominant in the study site. Avicennia alba was the species with the largest biomass and carbon content. The estimated biomass contained in Mekar Beach is 380.42 tonnes/Ha with carbon sequestration of 190.21/Ha.

Abstract

Global warming driven by rising greenhouse gas emissions has heightened the need to utilize green spaces as carbon sinks, one of which is the arboretum. This study aimed to determine the potential biomass, carbon stock, and CO₂ uptake of the vegetation in the Arboretum of Institut Teknologi Sumatera (Itera). A combination of destructive and non-destructive methods was applied across 12 plots representing three levels of vegetation density: high, medium, and low. The analysis covered biomass, carbon stock, and estimated CO₂ uptake. The results showed an average biomass of 50.51 tons/ha, a carbon stock of 23.74 tons/ha, and CO₂ uptake of 85.82 tons/ha. The highest values were found in the high-density vegetation area, which had a denser tree population. This study provides baseline carbon stock data for a developing campus arboretum in Sumatra, and concludes that, although the carbon stock of the Itera Arboretum remains lower than that of other arboreta, it nonetheless holds potential as a carbon sink that contributes to climate change mitigation. Practically, these results imply that arboretum management must prioritize intensive enrichment planting in low-density zones and establish permanent monitoring plots to optimize long-term carbon sequestration.

Abstract

Indonesia known for its high biodiversity, is home to various species of wildlife, with 17% of the world's wild animals found in its territory. However, this wealth makes Indonesia one of the major suppliers of both legal and illegal wildlife trade, which threatens conservation efforts. This study aims to identify the potential of wildlife trade, health factors, and the welfare of traded animals. Conducted in Bandar Lampung in February 2022, the research employed direct observation through structured interviews with pet shop owners, as well as document studies. The findings indicate that despite a post-pandemic decline, wildlife trade in the region still holds significant potential. Health factors, such as mouth ulcers in pythons and metabolic diseases in geckos, pose major challenges, although adequate care is provided in these shops. Animal welfare remains a critical concern, as dependence on wild-caught animals from the wild threatens their sustainability. This study emphasizes the importance of implementing sustainable management practices and adhering to existing regulations to ensure the continuity of wildlife trade in Indonesia

Abstract

Peat swamp forests in Indonesia face significant pressure due to ecosystem degradation. One example is in Ketapang Regency, West Kalimantan. Restoration efforts are needed to restore ecosystem function,  including revegetation with Ficus benjamina, which is adaptive to peatland conditions. The  restoration success rate is expected to improve with the use of. This study aimed to evaluate the effectiveness of different growing media on the growth performance of F. benjamina stem cuttings. This study used a completely randomized design (CRD) with 5 planting media treatments (P0–P4) and 8 replications. Parameters included plant height, stem diameter, number of leaves, and changes in soil chemical properties (pH and organic carbon), with supporting data of temperature, humidity, and rainfall as environmental factors. The results showed that planting media treatments significantly affected the vegetative growth of F. benjamina. Treatment P4 (peat + rice husk charcoal + compost) produced the best growth with an average height of 14.60 cm, stem diameter of 2.33 mm, and number of leaves of 8, compared to the control (P0) with a height of 11.25 cm, diameter of 1.11 mm, and 6 leaves. Furthermore, soil pH increased from acidic (4.6–5.0) to neutral (6.5–6.7). These results indicate that  combining planting media with organic matter effectively improves soil chemical properties and supports the growth of F.benjamina, thus offering potential for application in peatland restoration.

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.
