Ethnobotanical study of the non-medicinal plant by village communities in the karst area of Pacitan, East Java, Indonesia. Intl J Trop Drylands 6: 1-10. The local community of Pacitan District, especially in the karst area in several villages of Tulakan Sub-district, has a yard and farm usually planted with many species of plants that have various benefits. These plants are edible, animal feed, spices, biopesticides, and plant growth hormones. However, the knowledge of the local community of Tulakan Sub-district regarding the various benefits of plants is only known from generation to generation, conveyed orally and in daily practice habits, so a study is needed to document this information. This study aims to reveal the knowledge of local communities and the diversity of non-medicinal plant species to meet communities' daily lives. The location of research was carried out in 2 villages located in Tulakan Sub-district, Pacitan District, East Java, Indonesia, namely Bungur Village and Tulakan Village. Data was collected through field surveys and direct interviews using the snowball sampling technique. A total of 40 respondents were interviewed, with details 14 male and 26 female. Respondents with the majority of high school educational backgrounds have around 46-55 years old. The inventory of non-medicinal plants amounted to 60 species of angiosperm plants from 43 families. The plants used consisted of 34 species for the edible plants, 20 species for the fodder plants, 6 species for herbs, 1 species used for biopesticide, and 1 species used for natural growth hormone. Based on the study results, it is known that local people use plants as an edible plants with more diverse plant species compared to other uses.
Abstract. Nur AAI, Arifiani KN, Ramadhandi AR, Sabrina AD, Nugroho GD, Kusumaningrum L, Ramdhun D, Bao TQ, Yap CK, Budiharta S, Setyawan AD. 2022. Estimation of aboveground biomass and carbon stock in Damas Beach, Trenggalek District, East Java, Indonesia. Indo Pac J Ocean Life 6: 103-109. Vegetation plays a vital role in providing environmental services in the form of storing carbon which can mitigate climate change. This study aimed to calculate Aboveground Biomass (AGB) and carbon stock in Damas Beach, Trenggalek District, East Java Province, Indonesia using an allometric equation. Biomass and carbon data at a tree (dbh >20 cm) and pole (dbh 10-20 cm) levels were collected using sampling plots distributed randomly at three stations, namely mangrove vegetation (Station I), coconut plantation (Station II), and agroforestry (Station III). The results showed that across the three research stations, there were a total of 23 plant species classified as tree and pole levels. At tree level, Rhizophora stylosa Griffith had the highest carbon stock with a value of 85.48 MgC/ha, while the lowest value was Nypa fruticans Wurmb with 0.02 MgC/ha. Similarly, at the pole level, the species with the highest carbon stock was R. stylosa, with a value of 65.88 MgC/ha, and the lowest was Theobroma cacao L. with 0.11 MgC/ha. The mangrove vegetation (Station I) had the highest carbon stock value of 200.53 MgC/ha. In contrast, the coconut plantation vegetation (Station II) has the lowest total carbon stock, with a value of 84.68 MgC/ha. Conservation and management need to be improved in the Damas Beach area because if the area is disturbed, the ability of vegetation to absorb carbon will decrease.
Abstract. Aprilia D, Arifiani KN, Sani MF, Jumari, Wijayanti F, Setyawan AD. 2021. Review: A descriptive study of karst conditions and problems in Indonesia and the role of karst for flora, fauna, and humans. Intl J Trop Drylands 5: 61-74. The karst area in Indonesia covers an area of about 15.4 million hectares and is spread almost throughout Indonesia. It is estimated the age of karst in Indonesia started from 470 million years ago to the most recent about 700,000 years. The existence of this area shows that many of the Indonesian islands were once seabed but were later uplifted and hardened. Most of the karst areas in Indonesia are composed of carbonate rocks, and almost none are composed of other rocks such as gypsum, salt rock, and evaporite rocks. Karst in Indonesia can be classified based on its development and climate. The amount of water available in the karst area plays an important role in human life and so do flora and fauna around the karst area. The karst area functions as an ecosystem for the habitat of various animals and plants. The richness of flora and fauna of this karst area is extraordinary. Karst area plays an important role in economy, science, and human culture. In addition, karst areas have an important role in the ecosystem, such as providing clean water, limestone-based natural materials, and controlling climate change. Its role in ecological function is that karst areas can also be a source of CO2 gas absorption. About 9.5% (155,000 km2) of the total karst area of Indonesia was damaged due to limestone mining activities, logging of vegetation, and land conversion. Given the importance of karst and limestone ecosystems as non-renewable natural resources, it is necessary to do conservation to maintain the ecological function. Steps that can be taken for conservation efforts in karst areas include limiting the sale of raw limestone to outside the area, clarifying protected areas and cultivation areas, socializing the importance of preserving karst areas, providing skills or developing other business opportunities, and reclaiming used land and mining according to the level and type of damage. This study aims to describe the geographical conditions and karst problems in Indonesia so that the conservation measures taken are known and identify the role of the karst area for flora, fauna, and humans.

Review: Local wisdom of Baduy people (South Banten, Indonesia) in environmental conservation. Asian J Ethnobiol 2: 92-107. Baduy people live in Kanekes Village, Leuwidamar Subdistrict, Lebak District, Banten Province, Indonesia. Baduy people is a group of people who firmly adhere to the traditions of their ancestors where the entire social system is rooted in their religious system. The tribe that lives depends on nature and always maintains the balance of nature. This review is intended to find out the current state of life of the Baduy people in environmental conservation, the ability to utilize local wisdom (traditional ecological knowledge) to meet their needs and the possibility of sustainability in the future their way of life. This research was conducted by studying literature based on journals or other information media. The results showed that the Baduy people still hold strong beliefs and customs and day by day with great wisdom. Beliefs and customs that become Pikukuh (rules) have always been the philosophy of life and daily of Baduy. Traditional rules and Pikukuh sapuluh are the basis of life guidelines and produce Baduy culture both in thinking, acting and behaving. Mores as part of local wisdom still beholder firm considerably by Baduy people, and the mores have come to the self fortress for Baduy people in the face of modernization, included in matter preserve its environment. The forms of local wisdom behavior that are a form of sustainability of environment and conservation conducted by Baduy people, for example: (i) agricultural systems, (ii) residential systems, (iii) forestry systems, and (iv) conservation practices.
Abstract. Aprilia DA, Dianti, Arifiani KN, Cahyaningsih AP, Kusumaningrum L, Sarno, Rahim KAA, Setyawan AD. 2020. Review: Biogeochemical process in mangrove ecosystem. Intl J Bonorowo Wetlands 10: 126-141. The mangrove ecosystem, one of the unique and distinctive aquatic ecosystems, is located in the tidal areas of the coast coastal areas in the tropics and subtropics. Mangrove ecosystems have many ecological, environmental, and social benefits. Mangrove forests have the potential to become a potential resource. This review aims to determine the process and function of the biogeochemical cycle in the mangrove ecosystem. The research method used in this research is descriptive qualitative research methods and tends to use inductive analysis. The biogeochemical cycle acts as a cycle that cannot be separated from the mangrove ecosystem. Biogeochemistry is the process of circulating chemical elements or compounds that occur repeatedly and continuously. Biogeochemistry plays a role in maintaining environmental stability and maintaining life on earth. The biogeochemical cycle consists of energy flow and nutrient cycling. Energy flows consist of food chains and food webs. The nutrient cycles include water, carbon, nitrogen, phosphorus, and sulfur. Various chemical elements resulting from the cycle process are needed to survive living things in the mangrove ecosystem.
