Abstract

Tracer metal (ng/g) elements in water can be determined solely by a qualitative or quantitative analysis using preconcentration method. This method improves the sensitivity of Neutron Activation Analysis (NAA) into part per billion (ppb) levels, therefore the type and quantity of metal in the water of PDAM can be determined. Preconcentration method was performed by adding diethyldithiocarbamate (DDC) into water sample to produce complex metal sediment. The sediment was irradiated inside TRIGA 2000 reactor in P3TkN for 3 minutes with the pneumatic tube facilities and readusing γ-ray spectrometer. The result ensures diethyldithiocarbamate is possible to apply in preconcentrated method for NAA, the alkali and halogen disturbance ions could also be reduced. Quantitatively, elements in PDAM water are natrium, aluminium, clorine, zirconium, iodine, calcium, manganese, and magnesium. The magnesium and manganese concentration was 0.1 and 0.06 ng/mL.Key words: Neutron Activation Analysis, preconsentration, dietilditiokarbamat, magnesium, manganese.

Abstract

This experiment was performed to examine the effects of Ochratoxin A (OTA) during organogenesis period on fetuses brain growth and development. Thirty pregnant mice were divided randomly into 5 groups of 6. Ochratoxin A was dissolved in sodium bicarbonate and administered orally on seventh to fourteenth days of gestation at dosage of 0.5, 1.0, 1.5 mg/kg bw, respectively. The remaining animals were used as  an untreated control, and placebo were given by  Sodium Bicarbonate. At the age of 18-day pregnancy, mice were sacrified dan taken its brains. The fetuses brain growth and development  were observed by measure brain weight, cereberum width and length, cerebellum width and length, and the wall thichkness of cerebrum. Result of this studies indicated that OTA caused decreased of brain weight, the length and width of cerebrum and cerebellum, the wall thickness of cerebrum significantly.Key words: Ochratoxin A, brain, cerebrum, cerebellum, mice.

Abstract

Sarang semut plant is one of indigenous medicinal plants of Merauke region, the Papua province. Local people use the bulb of sarang semut plants to cure inflammation, muscle pain and enhancing immunity. However rare research of the plants has been done especially on the antioxidant activity. The objective of this research was to investigate the antioxidant activity of three species of sarang semut plants which were Myrmecodia beccarii, Myrmecodia sp. and Hydnophytum sp. The test was necessary to identify the inhibitory concentration level of plant extract in blocking a free radical (IC50). Parts of plants were extracted with maceration using methanol for 3 x 24 h to produce concentrated methanol.  Plant extracts of three species were then subject to   antioxidant activity test based on free radical blocking of 1,1-Difenil-2-Pikrilhidrazil (DPPH) qualitatively and quantitatively using Ultraviolet-Visible spectrophotometry. The results showed the methanol extract of M. beccarii, Myrmecodia sp. and Hydnophytum sp. were active as antioxidants with IC50 from 8.18 ppm, 21.79 ppm, 25.31 ppm, respectively while Vitamin C as a control has IC50 7.85 ppm. In conclusion, three  plant species of sarangsemut are potential  as natural antioxidant and plant extracts of M. beccarii showed the highest antioxidant activity among others. Key words: Antioxidant, sarang semut plants, Rubiaceae, DPPH.

Abstract

Amphibians and reptiles (herpetofauna groups) produced of many compounds. The herpetofauna and their chemical compounds have been the subject of intense research interest for many years due to their potential in medical application and in lead compound development for new drugs. A number of different types of compounds have been identified from the glandular skin secretions of amphibians and venom or saliva of reptiles. These compounds have been shown to be active against gram-negative and gram-positive bacteria, fungi, enveloped viruses, diabetes mellitus, hypertension and cardiovascular disorder.Key words: Herpetofauna, diabetes mellitus, hypertension, drugs, pathophysiology

Abstract

Papua is an area with very wide range, from lowland with altitude 0 m to highland area with 4730 m above sea level. Orchids species constitute the greater part of orchids diversity, which can grow on the bare branches of tall trees, or embedded in moss dripping in wet and cool mountain forests, as well as in the eternal shade of tropical rain forest. Numerous plants world-wide are threatened with extinction because of degradation or destruction of their habitat. Orchids are among the most threatened plants of all, especially when pressure from dealers and collectors aggravales the problems. South Papua is a lowland area with the elevation around 0-7 m above sea level, temperature 23-300 C, and 1500 m rainfall per year. The aims of these investigations were to explore the diversity of tropical orchids in South Papua. The exploration and collection were done in Asmat, Boven Digul, Mappi, and Merauke. The study found 22 genera and 75 species, mostly are epiphytic. Key words: orchids, exploration, diversity, South Papua.

Abstract

Bruguiera gymnorrhiza is a mangrove plant often called tanjang containing several chemical compounds such as saponins, alkaloids, tannins, flavonoids and polyphenols. The purpose of this study was to isolate and determine the toxicity of the methanol extract of bark, leaves and flowers of B. gymnorrhiza as a plant pesticide. Samples were extracted by maceration and soxhletation methods using methanol as solvent. Maceration and soxhletation were done for 24 h and 6 h, respectively. From distillation of maceration treatment was obtained 20.28% (bark), 15.95% (leaves) and 19.69% (interest). In soxhletation there were concentrations of 27.01%, 29.68% and 16, 46%. The results of the foam test and reagent-Buchard Lieberman (LB) showed that only bark and flowers contain saponins. Toxicity tests on mosquito larvae with flower extract by maceration was more toxic than bark; on the contrary bark extract was more toxic than flower extract by soxhletation. SPSS analysis showed LC50 values for flower extracts was 723.6 ppm and for bark extract was 673.9 ppm. Both bark and flower extracts containing saponins can be categorized as highly toxic (<1000 ppm). Therefore it can be used as a botanical pesticide against mosquito larvae.  Key words: mosquito larvae, mangrove tanjang (B. gymnorrhiza), saponins, pesticide.
