Abstract. Hernawati, Zuhud EA, Prasetyo LB, Soekmadi R. 2022. Synopsis of Sumatran Nepenthes (Indonesia). Biodiversitas 23: 4243-4255. Taxonomic status is a fundamental component in determining the conservation status of a species. Inappropriate taxonomic entities can mislead efforts to protect species, especially endangered ones. Determining the taxonomic status of Sumatran Nepenthes is an essential step in conserving these unique species. This study aims to assess the taxonomic status and update the compilation of scientific names and taxon positions related to the Sumatran Nepenthes. The morphological characters were collected through observation of herbarium specimens and field research in several locations in Sumatra. The grouping of species is built based on the similarity of morphological characters for each selected species and follows a taxonomic revision process. The results showed that Sumatra had 39 species of Nepenthes, which were previously known to occur in only 29 species. The increase in the number of Sumatran Nepenthes came from (i) The publication of 9 new Nepenthes species from Sumatra. (ii) Restores N. pectinata and N. xiphiodes as independent species from their original position as synonyms for N. gymnamphora. (iii) Positioning N. gymnamphora as one of the Nepenthes species on the island of Java. (iv) Positioning N. angasanensis, N. longifolia, N. talangensis, and N. tenuis as independent species and not synonyms of N. mikei, N. beccariana, N. bongso, and N. dubia

Abstract. Sitanggang NDH, Zuhud EAM, Masy’ud B, Soekmadi. 2022. Ethnobotany of the Toba Batak Ethnic Community in Samosir District, North Sumatra, Indonesia. Biodiversitas 23: 6114-6118. The Toba Batak ethnic community is one of the ethnic groups in Indonesia that is believed to have unique characteristics in terms of ethnobotanical aspects. The objectives of this study were to identify the diversity of plant species that were used and collected by the Toba Batak ethnic community, analyze their Cultural Significance Index and determine the economic potential of plant species of high cultural value. The survey was conducted in four villages near Samosir Botanical Gardens and Aek Natonang Lake. We collected data through field observations and interviews with key respondents of chiefs, healers, homemakers and youth as users. We analyzed the data to determine the number of plant species collected and used by the Toba Batak ethnic community, to calculate the cultural importance of the plant species, and to determine the economic potential of the plant species. The result showed that the community collected and used 146 plant species from 53 families. We distinguished it into three categories, food (66 species), medicine (67 species) and traditional rituals (13 species). Twenty plant species had the highest cultural value (ICS > 30). Nine species had the highest cultural value, i.e., ginger (Zingiber officinale) (54), rice (Oryza sativa) (50), garlic (Allium sativum) and turmeric (Curcuma longa) 48), mango (Mangifera indica) and sweet potato (Ipomoea batatas) (40), and lime (Citrus aurantifolia), kaffir lime (Citrus hystrix) and rambutan (Nephelium lappaceum) (39). Six of the nine plant species with high cultural value were considered potential and priority economic commodities. These species were ginger, rice, garlic, turmeric, mango and sweet potato.

Abstract. Trisnanto A, Soekmadi R, Arifin HS, Pramudya B. 2023. Utilizations and policy formulations of home garden (pekarangan) as agritourism area in East Java. Biodiversitas 24: 1450-1459. This study aims to determine the factors that play a role in successfully using a home garden (pekarangan) as an agritourism area. This is important as material for formulating designs for home gardens for sustainable agritourism areas. This research was conducted in Banyuwangi District, East Java Province. The data and information to develop a home garden utilization system were collected through field observations and interviews with relevant parties. This study uses Interpretive Structural Modeling (ISM) analysis to identify the determinants and develop design formulations for utilizing pekarangan for agritourism areas. The key elements of a system are generated from the interpretation of ISM analysis data, which shows the levels of system structure. ISM analysis was determined through an approach with five criteria to examine the binding strength within and between groups/levels, the relative frequency of oscillations/shocks, context, coverage (containment), and functional relationship, respectively. The results showed that management institutions need to develop financing schemes with financing institutions, both banks and non-banks, based on financial technology (fintech). As practical implications, affordable financing for farmers/providers of tourism products, with their aggregator avalists, is needed to improve the financial capacity of community-based tourism. The manager of the pekarangan agritourism area is an aggregator of regional business processes by building inter-village networks and connectivity to major tourist destinations. Thus, home garden-based agritourism is expected to create new tourism area units networked with the main tourist destinations to form network tourism destinations.

Abstract. Lesmana Y, Basuni S, Soekmadi R. 2024. Ecosophy as a form of protection for the Tapanuli Orangutan (Pongo tapanuliensis) in the Batang Toru Landscape, North Sumatra, Indonesia. Biodiversitas 25: 4535-4542. Forest clearing for economic development often conflicts with saving biodiversity. Forest clearing by humans to date has been anthropocentric in its utilization of forest resources, which are still classified as exploitative in the Batang Toru Landscape, South Tapanuli District, North Sumatra, Indonesia. As a result, the Tapanuli orangutan (Pongo tapanuliensis) become alienated in its own home and migrates to community gardens for get food. The community considers orangutans to be very cruel by stealing and destroying their plantation products, which results in a decrease in economic income, triggering human-orangutan conflict. Local communities carry out evictions in various ways based on their initiatives and experiences. This study aims to analyze the concept of ecosophy (ecological philosophy)and factors of human-orangutan conflict as an alternative conservation of wild and endangered species protection. The research location focused on six sub-districts of the Tapanuli orangutan range in the other-use forest area of South Tapanuli District. This research used qualitative methods through interviews and discussions with communities living around the forest. The results showed that the concept of ecosophy can integrate intellectual, spiritual, and emotional dimensions at all levels of education for public awareness of the importance of protecting the Tapanuli orangutan. Higher levels of education showed positive results towards saving the Tapanuli orangutan. This study suggests that a long-term solution to human-orangutan conflict requires a comprehensive approach that emphasizes the ecosophy between humans and nature.

Abstract

Background: Informal settlement upgrading requires collaborative arrangements that are responsive to local conditions and stakeholder configurations. Objective: This study maps the roles and relational dynamics of key actors involved in upgrading the Tomang Banjir Kanal informal settlement in Jakarta, Indonesia. Methods: Stakeholders were identified through in-depth interviews, field observations, and local census data. Stakeholder positions were analyzed based on their levels of interest and influence in the upgrading process, while inter-actor relationships were examined using social network analysis. Results: The findings indicate that key stakeholders in multi-actor collaboration include the West Jakarta Municipal Government/Mayor’s Office as the central operational coordination hub; the Jakarta Provincial Legislative Council (DPRD) as the actor responsible for strengthening political legitimacy, budgetary support, and oversight of sectoral agencies; and the Jakarta Provincial Housing and Settlement Agency as the technical and programmatic lead. These actors are supported by neighborhood leaders (RT/RW) and community figures who function as brokers of local aspirations and maintain social stability, as well as by the Kampung Collaboration Committee, which serves as an institutional bridge connecting government agencies, community groups, and developers. Conclusion: From a technical governance perspective, the National Land Agency (BPN) has limited direct involvement but plays an essential enabling role in resolving land tenure issues, which determine the feasibility of collaborative slum upgrading. These findings highlight the need for stronger inter-agency coordination, effective land tenure resolution, and community-based collaboration mechanisms to support sustainable and inclusive upgrading programs.

Abstract

The Danau Sentarum landscape in West Kalimantan, Indonesia, is a catchment area containing important peat wetland ecosystems that support biodiversity conservation, local livelihoods, and hydrological functions in the upper Kapuas River Basin. However, under Law No. 23/2014 on Regional Government, formal authority over watershed management in the forestry sector lies with the central and provincial governments, whereas regency governments retain responsibility for other sectoral functions that affect watershed conditions. This study examined the structural relationships among district government functions relevant to sustainablelandscape management in Danau Sentarum. Data were collected through a literature review, focus group discussions, and expert interviews with relevant institutional representatives and analyzed using Interpretive Structural Modelling. The analysis identified 30 functional elements and produced an inconsistency index of 9.56%. Environmental management, spatial planning, and land administration were positioned as the main driver functions with high driving power and low dependence. Agriculture, fisheries, tourism, trade, industry, labor, and energy and mineral resources formed linkage functions that connected ecological governance with naturebased production and local economic activities. Settlement, connectivity, investment, cooperatives and small and medium enterprises, social protection, community empowerment, and public order functions were positioned as more dependent outcomes. These results suggest that district-level watershed governance in the Danau Sentarum landscape may be improved byemphasizing environmental management, spatial planning, and land administration above the coordination of productive and welfare sectors. This study presents a function-based institutional map for district-level planning in Danau Sentarum, and requires additional validation to evaluate its use in other watershed environments.
