Abstract. Az-Zahra FR, Sari NLW, Saputry R, Nugroho GD, Sunarto, Pribadi T, Setyawan AD. 2021. Review: Traditional knowledge of the Dayak Tribe (Borneo) in the use of medicinal plants. Biodiversitas 22: 4633-4647. Dayak is the name for the native inhabitants of the island of Borneo. The Dayak Tribe uses natural and forest products in plants as traditional medicine for health treatment. This study aims to obtain information about the utilization of medicinal plants in the Dayak Tribe. The knowledge about traditional medicine by utilizing medicinal plants has been obtained from their ancestors since ancient times and inherited from generation to generation. The use of various medicinal plants used by the Dayak Tribe has differences in terms of the part of the plant taken, how to process it, and how to use it. This is because each Dayak Sub-tribe has its role model for using these medicinal plants. For example, the leaves are used in one area, and it could be that the plant roots are used in other areas. This paper reviews the use of medicinal plants to treat various diseases by 6 Dayak sub-tribes, namely: Desa Dayak Sub-tribe (member of Iban Dayak), Jangkang Dayak Sub-tribe (member of Klemantan Dayak), Bakumpai Dayak Sub-tribe (member of OtDanum-Ngaju Dayak), Kenyah Dayak Sub-tribe (member of Apokayan Dayak), Tagol Dayak Sub-tribe (member of Murut Dayak), and Siang Dayak Sub-tribe (member of Punan Dayak). The results from 6 Dayak Sub-tribes revealed 63 families of plants from which 133 species. The family most widely used for medicinal plants, namely Euphorbiaceae, consists of 9 species, and the leaf is the most commonly used part of the plants (47%). The traditional knowledge of the Dayak Tribe in utilizing plant resources will significantly help preserve biodiversity and domestication of medicinal plants. Suppose medicinal plants are exploited more than they should. In that case, it will undoubtedly have a significant impact on their availability in the forest area, and if it continues, it will cause the extinction of certain species. This implies the importance of preserving local wisdom in the Dayak Tribe so that the use of nature is done wisely and so that it remains sustainable. By knowing the benefits of medicinal plants, Dayak Tribe will want to conserve these medicinal plants to be used in the future.

Abstract. Khairunnisa H, Dewi MAK, Faqiih MAH, Putrayuda MR, Nugroho GD, Indrawan M, Sutarno, Sugiyarto, Supriatna J, Nursamsi I, Pradhan P, Setyawan AD. 2024. Prediction of potential climate change impacts on the geographic distribution shift of Casuarina junghuhniana and C. equisetifolia in Southeast Asia. Biodiversitas 23: 6360-6371. Global warming, driven by various anthropogenic activities, leads to an increase in earth’s surface temperatures, exerting a profound influence on global climate patterns. This phenomenon significantly impacts the growth patterns of various plant species, including Casuarina equisetifolia L., commonly known as sea cypress, and Casuarina junghuhniana Miq., referred to as mountain cypress. The primary objective of this study is to assess the potential repercussions of climate change on the distribution of these two species within Southeast Asia. To achieve this goal, the study utilized the MaxEnt modeling approach, incorporating key factors such as bioclimatic conditions, soil characteristics (edaphic factors), and UV radiation levels. Present study considered three distinct time intervals (2030, 2050, and 2080) while exploring four diverse climate change scenarios (RCP 2.6, RCP 4.5, RCP 6.0, and RCP 8.5). The findings of this investigation reveal that both C. equisetifolia and C. junghuhniana are susceptible to alterations in the extent of suitable habitat distribution, which result in shifts in their geographic ranges due to evolving climatic conditions. Initially, the habitat distribution encompassed an area of only 652,819 km2, accounting for 15.65% of the suitable habitat for C. equisetifolia, and 30,132 km2, representing 0.7% of the suitable habitat for C. junghuhniana. However, by the year 2080, the habitat range for C. equisetifolia is projected to expand significantly to cover 755,082 km2 (18%) under the RCP 4.5 scenario. In contrast, C. junghuhniana is expected to experience a notable reduction, with its suitable habitat shrinking to 25,332 km2 (0.6%) under the influence of RCP 8.5. Notably, these shifts are characterized by a southeastward migration of C. equisetifolia towards Indonesian Borneo from Malaysian-Indonesian border and an eastward shift of C. junghuhniana towards the east of Sulawesi from the Gulf of Bone. These findings highlight the dynamic nature of species distributions in response to changing climatic conditions, emphasizing the need for proactive conservation efforts and adaptive management strategies to mitigate potential ecological impacts.
