Abstract. Partasasmita R, Cahyani NT, Iskandar J. 2020. Local knowledge of the community in Cintaratu Village, Pangandaran, Indonesia on traditional landscapes for sustainable land management. Biodiversitas 21: 3606-3616.  Cintaratu, a village in Parigi Sub-district, Pangandaran District, West Java province, Indonesia has various landscapes. The recent developments of the community reflect a shift in values towards the attainment of economic prosperity. However, scaling-up the use of landscapes in this capacity can cause negative impacts. A cultural approach to landscape management can assist the village community in identifying sustainable practices. The purpose of this study was to elucidate the community's knowledge of the variety of traditional landscapes that exist in Cintaratu Village and the historical influence on variations in the landscapes. The qualitative method was applied in this study. The result of the study showed that some landscapes, i.e., leuweung karamat (sacred forest), kebon (garden), sawah (rice field), astana (grave/ tomb), pamukiman (residential area), pekarangan (homegarden), walungan (river), solokan (small river), tampian (bathing and washing place for residents), and balong (fish pond) are documented in Cintaratu Village. On the basis of ecological history, it has been revealed that village community’s behaviors have changed various landscapes in Cintaratu Village. Conservation efforts carried out by the people themselves towards the traditional landscapes are usually associated with a customary prohibition or pamali that develops in the village community. The local people of Cintaratu recognize various landscapes that can be classified as natural and cultural landscapes. Based on the information provided by informants, the village landscape changes can be traced from the 1780s to 2019. The history of these landscape changes is the result of various factors, including an increase in population density, the implementation of government policies, and market economic development in the village.

Abstract. Muhlisin, Iskandar J, Gunawan B, Cahyandito MF. 2021. Vegetation diversity and structure of urban parks in Cilegon City, Indonesia, and local residents’ perception of its function. Biodiversitas 22: 2589-2603. The existence of urban parks is very essential for cities because they provide ecosystem services and benefits to humans. Diversity and structure of vegetation in urban parks play significant role in delivering several functions of ecosystem services. This paper aims to explore and analyze the vegetation diversity and structure, as well as ecosystem services of eight urban parks in Cilegon City, Banten Province, Indonesia. Vegetation analysis and residents’ perception are also conducted in this research. The analysis of vegetation is focused on horizontal structure of vegetation, including plant diversity, plant habitus, the original distribution of the plants, and vertical structure of vegetation (canopy stratification and vegetation profile). The residents’ perceptions are collected using interviews of selected respondents. The identification of vegetation recorded 114 plant species from 46 families are found in the concerned urban parks, however, the diversity and species richness in these parks tended to be low. The vegetation communities are uncertain and dominated primarily by non-native and invasive species. The canopy stratification is relatively homogeneous with the dominant plants having less than one meter in height, such as Ruellia simplex and Syzygium paniculatum. The vegetation planted in the urban parks are mostly ornamental plants that provide much more aesthetic function rather than ecological purpose, daily human needs, or other ecosystem services. This fact shows that urban parks in the study area have only few ecosystem services, hence they need some improvements in order to have more environmental services and to be able to enjoy more by the community.

Abstract. Mutaqin AZ, Husodo T, Kendarto DR, Wulandari I, Shanida SS, Megantara EN, Kurniadie D, Iskandar J, Nurzaman M. 2022. The ecology of suweg (Amorphophallus paeoniifolius) in the Citanduy and Cimanuk Watershed, West Java, Indonesia. Biodiversitas 23: 6520-6529. Suweg (Amorphophallus paeoniifolius (Dennst.) Nicolson) is one of the plants distributed in Indonesia, including in the Citanduy and Cimanuk Watershed. Amorphophallus grows in various land cover types. This species exhibits wide agroecological adaptation to dry and moist lands. Citanduy Watershed passes through the Leuwikeris Dam, and the Cimanuk watershed passes through the Kertajati International Airport. These projects can affect the condition of the surrounding environment, including biodiversity. This study was conducted to observe the distribution, population, and habitat characteristics of the suweg in the Citanduy and Cimanuk watersheds. Exploratory surveys and intensive studies were applied in this study. An exploratory survey was conducted randomly through direct observation. An intensive study was carried out to determine the ecological description of suweg in several areas, namely Kuta Subvillage, Ciangir Subvillage, and Pasiripis Village, with existing projects, still have strong local cultures, and the discovery of suweg growing. Suweg is growing in several sites, including the Citanduy and Cimanuk Watersheds, with certain elevations and environmental conditions. The Summed Dominant Ratio (SDR) of suweg in Kuta Subvillage, Ciangir Subvillage, and Pasiripis Village in the home garden and garden, respectively, are 8.50 and 13.77; 10.07 and 19.25; and 0 and 22.92, which indicate the population or density of suweg is low. The abiotic and biotic environmental parameters observed at each site varied.

Abstract. Mutaqin AZ, Iskandar J, Irawan B, Suryana, Kurnadie D, Nurzaman M, Shanida SS. 2023. The local knowledge and potential of suweg (Amorphophallus paeoniifolius) in the Citanduy and Cimanuk watersheds of West Java, Indonesia. Biodiversitas 24: 370-378. The Indonesian archipelago is rich in natural resources and ethnic diversity. Each ethnic group interacts with the surrounding environment in ways that often differ. Interaction with the environment creates local knowledge that is complex in terms of language, practical understanding, beliefs, and social interaction. One useful natural resource that grows in many areas of Indonesia, especially in watershed ecosystems, is Suweg (the elephant foot yam) which has the scientific name Amorphophallus paeoniifolius (Dennst.) Nicolson. Local communities, such as in the Citanduy and Cimanuk watersheds of West Java, use suweg for various purposes in their lives. The study reported here aimed to document the local knowledge and development potential for suweg in the Citanduy and Cimanuk watersheds, West Java, Indonesia. The research used mixed observation methods, predominantly qualitative. The data collection technique was purposive, based on interviews (structured, semi-structured, and in-depth interviews) with several informants or community groups who were considered competent to know suweg. Data were analyzed through emic and ethical approaches. Data analysis was conducted by cross-checking, summarizing, and synthesizing. The results of the research showed that suweg grows in a range of environmental conditions on managed agroecosystem lands. The corms of suweg are peeled, cooked and eaten in a variety of side dishes. The leaves of suweg have been used as food for fish in pond-system aquaculture. The results of this study suggest that suweg has the potential for expanded development, based on sociological and ecological evidence.

Abstract. Irawan B, Safira KM, Annisa, Rohmatullayaly EN, Ihsan M, Suryana, Iskandar J, Iskandar BS. 2024. Ethnobotany of cassava (Manihot esculenta) in the traditional peri-urban Sundanese community of Cireundeu Hamlet, Cimahi City, West Java, Indonesia. Biodiversitas 25: 116-128. The community of Cireundeu Hamlet is one of the Sundanese traditional communities that still maintain wisdom in processing and using cassava (Manihot esculenta Crantz) as staple food (rasi) and foodstuff. Many landraces of cassava have the potential to develop into superior varieties, and research is necessary to make cassava a year-round food. The aim of this study is to elucidate the ethnobotanical knowledge of the rural Sundanese community on cassava, namely on various landraces and their folk classification, traditional farming management, and uses. Based on a case study of the traditional people in a peri-urban area of Cireundeu Hamlet, Cimahi City, West Java, Indonesia, mixed methods, i.e., qualitative and quantitative, were used in this study. There are seven landraces of cassava used as foodstuff that are traditionally managed by the Cireundeu people, including sampeu apuy, sampeu bodas, sampeu gambir lembang, sampeu garnawis, sampeu hideung, sampeu karihkil, and sampeu mentega. Based on Relative Frequency of Citation, the highest values are sampeu bodas (0.96) and sampeu garnawis (0.93). These cassava landraces can be distinguished by the Cireundeu people based on characteristics of petiole color, stem color, apical leaf color, leaf color, and taste of the tubers. Based on folk taxonomy, cassava is classified into five levels: level 0 (unique beginner), known as tutuwuhan and pepelakan (plants); level 1 (Life form) known as beubeutian (tubers); level 2 (generic) known as sampeu karet and sampeu, a genus from Manihot esculenta; level 3 (species) known as sampeu (sweet-cassava, Manihot esculenta Crantz) and sampeu karet (bitter cassava, M. carthagenensis subsp. glaziovii); and level 4 (specific). The processing and use of cassava are carried out both in traditional and modern ways, including using apical leaves as lalab or boiled vegetables and using the roots as the basic ingredients for making rasi (sangueun), tapioca flour, and snacks.
