“…Moreover, shrub and tree species such as Melastoma and Macaranga were also traditionally used by Dayak people and local farmers in East Kalimantan as the natural key plant species indicator to determine the end of the recovery period of forest land after ground fire or shifting cultivation activities (Amirta et al 2016b;Susanto et al 2016;Imang et al 2008). (Kiyono and Hastaniah 2005;Arung et al 2017;Goh et al 2017).…”

Abstract. Yuliansyah, Haqiqi MT, Septia E, Mujiasih D, Septiana HA, Setiawan KA, Setiyono B, Angi EM, Saparwadi, Sari NM, Kusuma IW, Rujehan, Suwinarti W, Amirta R. 2019. Short Communication: Diversity of plant species growing during fallow period of shifting cultivation and potential of its biomass for sustainable energy production in Mahakam Ulu, East Kalimantan, Indonesia. Biodiversitas 20: 2236-2242. Fallow period is a time gap, as long as 15 years, for improving natural soil fertility of land used for traditional shifting cultivation, in the tropical areas commonly used by Dayak People in Borneo Island. During this period, many biomass plant species naturally grow and develop a new forest vegetation community with shrub and medium trees, dominated by fast-growing pioneer species. In this study, we investigated the plant diversity in fallowed shifting cultivation area in Batu Majang Village, Mahakam Ulu District, East Kalimantan Province, followed by analysis of the suitability of wood characteristics for energy production. We classified the study area according to the age of fallow period as: 1-3 years, 4-6 years, 7-9 years and 10-15 years. We found 29 species among which 13 were identified as the top species according to the highest value for important value index. Potential wood biomass production increased from 3.01 m3 ha-1 to 399.62 m3 ha-1. V. pinnata and M. pearsonii showed the highest dominance which is present in almost all area based on age classification groups. Wood from V. pinnata achieved the highest calorific valueof18.00 MJ kg-1 whereas N. cadamba and M. sericea were in the second and third places with the value of 17.30 MJ kg-1 and 17.28 MJ kg-1, respectively. Therefore, V. pinnata was an important species among all other species observed because of high adaptability and high energy content. In addition, possible energy production at the end of the fallow period of 15 years was 2.92 GJ ha-1.

Several of those important medicinal plants have been reported by Goh et al (2017), but extensive researches on those plants are currently pursued. One of those plants is Aidia borneensis, a Bornean endemic plant and locally known as Sambah bagangan, belonging to Rubiaceae family (Goh et al, 2017).…”

We investigated the total antioxidant capacity of Aidia borneensis leaf infusion, a Bornean endemic plant, which is traditionally consumed as a home-remedy beverage in Brunei Darussalam. The antioxidant capacity of the infusion of A. borneensis leaves was evaluated by 2,2-diphenyl-1-picryhydrazyl (DPPH) radical-scavenging ability. We found that the infusion shows a relatively high antioxidant capacity, and it was attributed to its high phenolic, flavonoid, and flavanol contents which were evaluated by Folin-Ciocalteu reagent, colorimetric assay, and aluminum chloride colorimetric method, respectively. By comparing its total antioxidant capacity, we estimated that the infusion of A. borneensis leaves is in the middle rank among twelve different commercially available Camellia sinensis teas. Our findings would have significant implications on A. borneensis products from Brunei Darussalam and on the feasibility of establishing this new beverage among the commercially available conventional C. sinensis and herbal teas.

BACKGROUND: Vitex pinnata is known as Laban, which is a medicinal plant used traditionally for generations to generations. Laban leaf extract with various concentrations has antibacterial activity. Laban leaf extract is known to inhibit the formation of Streptococcus mutant in human teeth. AIM: To exam, the minimum inhibitory concentration (MIC) and minimum kill concentration (KBM) extract Laban leaves (V. pinnata) as an antibacterial against Streptococcus mutants. METHODS: This research was purely experimental research with design randomized pretest-posttest and control group. The study was conducted at the Laboratory Microbiology Faculty of Animal Health, Syiah Kuala University, Banda Aceh, from March to June 2019. The sample of this study was the Laban leaf from the Aceh Besar geothermal area. This research included preparation raw materials, chemical characterization of raw materials, determination of minimum and maximum components mixture, determining the optimum formula based on the best inhibitory potential, inhibitory testing antibacterial, standardized test, and test (one-way ANOVA). RESULTS: MIC of n-hexane extract showed the results of calculations; the percentage of bacterial inhibition was at a MIC of 1.56% on average colony −1.45 CFU/ml. In ethyl acetate extract, the MIC was 0.20% on the average colony −0.17 CFU/ml. The methanol extract can inhibit bacteria at the smallest concentration of 0.05% average colony −1.48 CFU/ml. Methanol extract inhibits bacteria more quickly. Concentration results minimum kill was 1.56%, 0.78%, 0.39%, 0.20%, 0.10%, and 0.05%. The smallest concentration of extract (n-hexane, ethyl acetate, and methanol) can kill Streptococcus mutans bacteria that are marked in the absence of bacterial colonies on microbiological growth media. CONCLUSION: Extracts of n-hexane, ethyl acetate, and methanol from Laban leaves have inhibitory activity on the growth of S. mutans bacteria. The smallest concentration of extract (n-hexane, ethyl acetate, and methanol) is able to kill S. mutans bacteria.
