Abstract

Setyayudi A, Krisnawati, Nandini R. 2019. Short Communication: Exploration of bidara laut (Strychnos lucida) parent trees in Gunung Tunak Ecotourism Park, West Nusa Tenggara, Indonesia. Biodiversitas 20: 274-278. Bidara laut (Strychnos lucida R. Brown) is one of the widely used medicinal plants. There is a bidara laut wood processing industry in West Nusa Tenggara that produces drinking cups called ‘health cups’ utilizing bidara laut. All raw materials used for the production of health cups are, however, obtained from bidara laut stands in forest areas, which may cause the extinction of this medicinal plant species if the highly intensive raw material harvesting in the forest is not supported with cultivation of this plant species. To preserve this plant species, the Institute for Research and Development of Non-Timber Forest Products Technology (NTFP-RDI) has carried out breeding activities by developing a collection garden of this species from the populations of Bali and West Nusa Tenggara (Lombok and Sumbawa Islands). The initial step carried out was the exploration of the parent trees followed by collection of generative materials (seeds) and nurseries. Exploration of bidara laut parent trees on Lombok Island was carried out in Gunung Tunak Ecotourism Park using a purposive sampling method, followed by collection of fruits to obtain seed propagating materials for establishment of seedling nurseries. Twenty-five parent trees were identified with average height of nine m, stem diameter of 24 cm and stem straightness scales of 1-3. The average seed produced was 413 seeds tree-1. Three parent trees were selected based on the highest seed germination rates, namely parent trees number 6, 14 and 20. This result provides useful information for the next bidara laut breeding activities.

Aktivitas Antikoagulan dari Tumbuhan Kayu Ular (Strychnos lucida R.Br.)

“…Kayu ular merupakan salah satu tanaman obat yang banyak digunakan sebagai obat tradisional. Daerah Indonesia Timur yang memiliki industri pengolahan kayu ular adalah NTT (Setyayudi et al, 2019).

Comparison of the combinations of water and ethanol extract of Strychnos ligustrina blum wood with Dihydroartemisinin- Piperaquin Phosphate (DHP) as an anti-malaria in mice infected P. berghei ANKA

“…S. ligustrina is a traditional anti-malarial medicinal plant that is commonly found in Indonesia, especially in West Nusa Tenggara (NTB) and Bali. The regions of Bima and Dompu (NTB) recognize it as Songga wood, in Bali, it is better known as part wood [5]. Based on literature studies, there are still very few reports on the antimalarial activity of the wood compound S. ligustrina.…”

Effect of Soil Amendments to Survival Rate of Bidara Laut (Strychnos lucida R.Br.) in the Mount Tunak Natural Tourism Park, West Nusa Tenggara

“…Mount Tunak N a t u r a l To u r i s m P a r k h a s w a r m a n d d r y characteristics with low rainfall, high temperature, and limited groundwater that become the challenge for the initial growth of S. lucida planting trials (BKSDANTB 2016). The lowest recorded rainfall was 181 mm/year (Mansur 2020), with daily temperatures averaging above 30°C and 14% humidity (Setyayudi et al 2019). Mount Tunak, Natural Tourism Park, has lower rainfall and humidity but higher daily temperature than the S. lucida natural habitat (Setiawan 2014b).…”
