Judul: The Influence of Urbanization on Gayo-Lut Traditional Knowledge and Biodiversity conservation through Culinary-Based Ecotourism
Abstrak: The wealth of natural resources can be utilized to support food security through the production of food, increased income access, and safe-sanitary food preparation. The utilization of food plants is reflected in the community’s traditional knowledge of how they were used, protected, and preserved for a long time as a cultural custom in traditional cuisines. One of the great challenges to sustaining the sustainability of food plants is urbanization and modern lifestyle. Several studies have found that the process of becoming more urban has a negative impact on natural resource knowledge and that urbanization is related to the loss of the ability to recognize and understand plants. A strategy that can be used to enhance biodiversity and sustain ecosystem service is the combination of traditional knowledge and culture which can be seen in their traditional cuisines. Unfortunately, there is more traditional knowledge that is passed down in oral form through stories, experiences, and language than stored documentation. This could potentially lead to knowledge loss if people start not knowing their food plants because of the difficulty in adapting to food plants in new places. This research was conducted on the Gayo Lut community in two locations to see the effect of urbanization. The first group was in Mude Nosar Village, Central Aceh in November-December 2020, and the second group was in the Gayo community, Musara Gayo in the Jakarta-Bogor-Depok-Tangerang-Bekasi (Jabodetabek) area in March-April 2021. The next research respondents grouped more specifically, namely the elder group (>59 years in Mude Nosar Village; 16 respondents), rural (<60 years in Mude Nosar Village; 16 respondents), and urban (<60 years in Jabodetabek; 16 respondents). Data collection was carried out in 2 stages. The first stage is an interview using the freelisting technique, and a semi-structured interview to identify the traditional knowledge of food plants, traditional cuisines, and details regarding their utilization. Then the second stage is a field study that aims to map the coordinate distribution of food plants and tourist objects. Freelisting data were analyzed using Anthropac and the Jaccard index to see species diversity and the effect of urbanization. Then analyzed descriptively. The coordinate data for the distribution of food plants and the distribution of tourist objects that have been obtained are mapped using ArcMap to see their distribution. The results of the study found that urbanization affected the community's traditional knowledge. This can be seen from the differences in the types of important food plants between each group due to adaptation to changing times and location of residence. But on the other hand, urbanization also offers a modification of traditional knowledge in traditional cooking which still maintains the authenticity of the distinctive taste of dishes. The adaptation is done with add up or substitution ingredients which easier to find in Jabodetabek. In three communities studied, recorded 188 species (elder 120 species; rural 116 species; urban 124 Species) of food plants are used by the community. For elder and rural groups, lasun ilang (Allium cepa) being the most important species because it is a major economic source besides coffee and rice. Then, there is

Judul: Kajian Etnobotani Masyarakat Kampung Adat Dukuh Kabupaten Garut, Jawa Barat
Abstrak: The people of Dukuh Cultural Village Garut Regency, West Java are a group of community who live in traditional life pattern, respect the culture and tradition of their ancestor and stay in simply way. The usage of plants traditionally by local people is decrease keep pace with the modern development. This condition may occur to the people of Dukuh Cultural Village. Therefore the study concerning the ethnobotany of local people at Dukuh Cultural Village should be done. This study was conducted during June and September 2009 using literature study, interview and questioner, survey and field invent methods. This study was the early documentation of indigenous knowledge of Dukuh Cultural Village people. It is hopefully the result can be delivered and developed by young generation of Dukuh Cultural Village and people in general. The study invented 292 species of plants from 81 families of plants. The most family that invented was Fabaceae with 28 species. Those plants were categorized into 12 groups according to their usages. There are 101 species of food plant, 34 species of firewood, 47 species of buildingmaterial plant, 19 species of aromatic plant, 150 species of medicinal plant, 24 species of handicraft-material plant, 8 species of bio-pesticide, 33 species of cattle feeding, 16 species of ritual purpose-plant, 51 species of ornamental plant, 7 species of coloring-material plant and 3 species of drink-material plant. The result shows 194 species (66,44%) are cultivated plants, 74 species (25,34%) are wild plants, 24 species (8,22%) are categorized as the wild and cultivated plants. The location where the species of plants were invented consist of garden (148 species; 30,08%), yard (136 species; 27,64%), un-irrigated field (82 species; 16,67%), forest (71 species; 14,43%), edge of street (34 species; 6,91%) and rice field (21 species; 4,27%). The part of plants dominated used is leaf (110 species ; 22,45%) while fruit-skin (1 species ; 0,2%) is the lest. The total of habitus was dominated by herb (146 species; 50%). The bush is the minority (2 species; 0,68%). The main commodities are rice (Oriza sativa) as the main plant, clove (Syzygium aromaticum) and teak (Tectona grandis) as the main plant for increasing the local people’s economic. The food plant consists of vegetable, fruits and carbohydrate production-plants. The species of plants that are used for building and firewood are relatively same, only the parts of plants are different. Teak (Tectona grandis) and kihiyang (Albizia procera) are species that mostly used by the local people to build their houses. Aromatic plants has functions for additive and flavor substance of food, room camphor and clothes camphor. One of the important usages is for medical purpose. The practice of traditional medical that easy to see is medical treatment of pregnant, puerperal and post puerperal woman by an indigenous medical. The ornamental plants are taken from the forest, both inside of forest area and outside of area. The plants for ritual purpose are usually used in expressing of gratitude to God and religious event. The cattle feeding plants are used to feed goats and sheep. Bio-pesticide is for eradicating the plants’ pest. The
