Abstract: Sterculia quadrifida R.Br. Bark decoction is used to treat hepatitis and consumed as a tonic by Timorese in the East Nusa Tenggara Province, Indonesia. Raw herbal materials are susceptible to fungi contamination, have limitations in transportation, and have low economic value. Processing the bark into powder packed in tea bags is expected to overcome these obstacles. Stevia, ginger, and mint leaves are herbs often added to herbal drink formulas. This study aimed to evaluate the antioxidant capacity, total flavonoid content (TFC), total phenol content (TPC), physicochemical properties, and sensory properties of six formulas, namely: (F1) pure S. quadrifida bark (F2) bark of S. quadrifida and leaves of stevia (F3) stem bark of S. quadrifida and ginger (F4) bark of S. quadrifida, stevia, and ginger (F5) bark of S. quadrifida and mint leaves (F6) bark of S. quadrifida, stevia, and mint. Total phenolic content was measured using the Folin-Ciocalteu method, and total flavonoids were determined using the AICI3 method. Antioxidant activity was measured using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) method. The TPC of S. quadrifida tea ranged from 14.09±0.7 to 68.20±0.95% Gallic Acid Equivalent (GAE), and the TFC ranged from 0.03±0.005 to 0.09±0.004% QE. The Ascorbic acid Equivalent Antioxidant Capacity (AEAC) of F1, F2, F5, and F6 were insignificantly different. F1 contained the highest levels of antioxidants (1,044.3±28.48 ppm Ascorbic Acid Equivalent (AAE)). Formulas with the addition of stevia, mint, and ginger showed weaker antioxidant activity than pure S. quadrifida. F1 and F2 have the potential to be developed as commercial herbal teas

Abstract: Faloak (Sterculia quadrifida R.Br) is a medicinal plant used by people in the province of East Nusa Tenggara to treat hepatitis. This study aims to determine the acute toxicity of faloak (Sterculia quadrifida R. Br) bark ethanol extract in Sprague-Dawley (SD) male white rats. The method used is experimental using post-test only control group design. In this study the parameters used are body weight, clinical symptoms, clinical biochemistry (ALT & AST), histopathology of liver organ and mortality in rats. Twenty male Sprague-Dawley rats were randomly assigned to 5 groups, group 1 as control, group 2 was administered orally faloak bark ethanol extract at dose of 40 mg / kg body weight, group 3 at dose of 200 mg / kg body weight, group 4 at dose of 1000 mg / kg body weight and group 5 at dose of 5000 mg / kg body weight. Results of observation for 24 hours there are no dead rats, so the value of LD50 extract ethanol faloak is 5,000 mg / kg body weight. Observations were conducted for 14 days to observed delayed occurrence of toxic effects. Oral administration of the faloak bark ethanol extract reduced the level of AST and ALT. The histopathology observation of rats liver cells showed liver cell necrosis at treatment doses of 200 - 5,000 mg / kg body weight.

Abstract: The increasing need for agricultural land has led to a shift in the cultivation of vegetation on peatland especially food crops. Agricultural activities on peatland require careful planning, appropriate technology application, and proper management due to the marginal and the fragile peatland ecosystem. Research and development are needed to evaluate the carrying capacity of environmental impacts on peatland use. This study aimed to obtain information on the water quality of peat domes, primary canals, and secondary canals of Block C, Pulang Pisau Regency. The study area is now mostly used for agricultural activities. The analysis was carried out in a descriptive qualitative manner based on water parameter testing results to assess the water quality of peat domes, primary canals, and secondary canals of each type of peatland use in Buntoi, Garung, and Kanamit Barat Village. The results indicated that five chemical parameters exceeded the water quality criteria for Class II PP No. 22/2021 namely BOD, COD, free chlorine, zinc, and lead in Buntoi. Further, in Garung, six chemical parameters exceeded the water quality criteria: DO, BOD, COD, free chlorine, lead, and copper. Meanwhile, in Kanamit Barat Village, seven chemical parameters exceeded the criteria: DO, BOD, COD, free chlorine, zinc, lead, and copper. Based on this research, therefore, agricultural activities on this peatland area should consider the natural characteristics of peat water and the selection of suitable plants.

Abstract: Kayu papi or shrub sandalwood ( Exocarpus latifolius R.Br.) is a hemiparasitic plant, member of Santalacea family which incorporated host plant on their nutrient absorption. Kayu papi is a fragrant wood that can mimic and perhaps substitute sandalwood ( Santalum album Linn.). Many studies recorded that exocarpic acid derived from kayu papi is also beneficial as a tuberculosis remedy. However, the information on silvicultural techniques has only been investigated just a few times. This study aimed to examine the effect of host plants and media combination on kayu papi’s growth under the nursery condition. Kayu papi seedlings were planted with five different hosts and control (without host plant) on six different media. The parameters are the height and diameter of the seven-month kayu papi seedlings. The result indicates that host plants significantly affected kayu papi’s growth. The interaction between the host plant ( Alternanthera spp. ) and media combination latosol soil and manure also significantly promoted the height of kayu papi . While kayu papi grown in grumusol with Saorupus androgynous host showed the highest diameter on average. In conclusion, kayu papi seedlings indicate that host plant presence and particular media optimized their growth.

Abstract: Exocarpus latifolius R.Br. known as Kayu Papi or shrub sandalwood, naturally occurred in East Nusa Tenggara. This species classified as fragrant wood and, on some occasions, has become sandalwood ( Santalum album Linn) substitution. This species is beneficial as a medicine. A recent study indicated that Exocarpic acid isolated from Papua New Guinea origin empirically cures tuberculosis in the in vitro treatments. However, the study of the biological compound of this species from the region is little known. This research is aimed at elucidating chemical compounds in the Kayu Papi wood originating from East Nusa Tenggara. The method was using GCMS analysis of the essential oil through prior steam distillation. The result revealed that thirty-two compounds represent 99.94% of essential oils, with six major peaks in approximately 41 minutes’ retention in total. The six-dominant compound of oils were Benzeneethanamine, alpha-methyl-N- ( phenyl methylene ) 34.37%, Alpha-curcumen (14.05%), Tridecane, 2-methyl-2-phenyl (11.2%), Alpha-calacorene (6.40 %), Levometh hetamine (4.46%), Benzene , ( 1-1-dimethylnonyl ) (4.11%). Whereas the twenty-six remaining components were less than and just over 3% each. There was no exocarpic acid identified, but some compounds are identical to sandalwood or other fragrant wood. The study may complement Santalacea’s list of chemical compounds to distinguish sandalwood and other fragrant wood.

Abstract: Objective: Sterculia quadrifida R. Br. of Sterculiaceae family is locally known as “Faloak” in East Nusa Tenggara Province, Indonesia. S. quadrifida is used in folk medicine to treat hepatitis, rheumatism, and to recover stamina. The aim of this study was to determine the total flavonoids, total phenolic content (TPC), and antioxidant activity of extracts from different plant parts of S. quadrifida. Methods: The s led parts of S. quadrifida were non-stripped stem bark, new regrown stem bark, old regrown stem bark, root bark, branch bark, and leaves. Stem bark was classified into three categories, namely, bark that has never been peeled (non-stripped stem bark), old regrown stem bark (estimated to be months after debarking), and new regrown stem bark (estimated to be months after debarking). Total flavonoid content (TFC) was determined by colorimetric aluminum chloride method and TPC was measured using Folin–Ciocalteu’s reagent. Antioxidant activity was determined with 2,2-diphenyl-1-picrylhydrazyl (DPPH). Results: The concentrations of flavonoids in S. quadrifida extracts from different plant parts varied from 0.58±0.13 to 1.25±0.10 mg QE/g. The TPC in the extracts of different plant parts ranged between 8.61±0.09 and 10.43±0.08 mg GAE/g. Branch bark has the highest total flavonoid and phenolic content. The extract of new regrown stem bark exhibited potent antioxidant activity with inhibitory concentration (IC50) values of 2.51±0.03 μg/ml. Conclusion: This study demonstrated for the first time that extracts from different plant parts of S. quadrifida exhibited strong antioxidant activity. However, the total phenolic and flavonoid contents in S. quadrifida only indicated a weak correlation with its antioxidant activity.
