Abstract

ne heavy metal, which is potential as pollutant, is cadmium that has been accumulated in soil and sediment. Although, cadmium is non essential element for plants, it is easily adsorbed and accumulated by various plants. The negative effect of cadmium on plants is that it can prevent the absorption of nutrition so that the plant growth will be inhibited and then the plant will die. Therefore, it is necessary to reduce the concentration of cadmium to be used as good growth media. Several methods of heavy metal accumulation, such as physical, chemical and biological methods, have been used, but the three methods have been considered as less effective methods. The use of plants to accumulate heavy metals in polluted soil is considered as a good method because the method is a safe method and can increase the soil fertility. In this research, accumulation of cadmium has been conducted by using Ipomeae reptans Poir. Result showed that the highest concentration that can be accumulated by I. reptans Poir was 3317.68 mg/kg of dried mass with the plantation time of 21 days. The increase of concentration in the growth media increased the cadmium concentration accumulated. The high accumulation of cadmium showed that I. reptans Poir is a hyperaccumulator plant for cadmium. The bioconcentration value was higher than 1, whereas the translocation factor was lower than 1 indicating that the accumulation mechanism was phytostabilization.Keywords : cadmium, accumulation, analysis, Ipomoae reptans Poir.

Abstract

Paliasa is one of tropical plants that used as an etnobotanical traditional drug by the people of South Sulawesi. Paliasa leaves is believed and used as a drug for hypertension, diabetes mellitus, cholesterol, and hepatitis diseases. Preliminary study was done by Brine shrimp lethality test with Artemia salina to a tissue part of one of type paliasa, Melocia umbellata (Houtt.) Stapf. var. degrabrata K. The result show that the wood of this plant is the most active with LC50 value of 1,80 ppm. Keywords : Paliasa, traditional drug, M. umbellata, bioactivity.

Abstract

Poli(asam laktat) diol (PLA-OH) telah disintesis melalui reaksi polimerisasi kondensasi asam laktat dan 1,4-butanadiol. Berat molekul rata-rata (Mn, Mw, dan Mz) PLA-OH ditentukan dengan analisis menggunakan Gel Permeation Chromatography (GPC). Viskositas intrinsiknya diukur pada konsentrasi 0,2 g/dL dan temperatur 298 K menggunakan pelarut kloroform. Melalui metode numerik berhasil ditentukan nilai a dan K dalam persamaan Mark- Houwink-Sakurada untuk PLA-OH, yaitu [η] = 3,532 x 10-4Mv 0,628 = 3,532 x 10-4qMHS 0,628 = 3,415 x 10-4Mw 0,628

Abstract

The objectives of the study are to describe the iron content of seagrass area ecosystem and its relation with nature of physico-chemical territorial water. The sampling of seagrass was conducted in purposive sampling technique for every status of the field and performed in three spots of the seagrass ecosystem region with reference to the depth of water and the current direction. Based on statistical tests of factorial and variance analysis indicate that the quality of physico-chemical territorial water in the coastal region of Donggala regency still very good, relatively. The result also showed, The Demand Oxygen and the turbidity gave a positive effect to Fe- seagrass improvement in its various association. Besides, the limiting factor for the low of Fe-seagrass is the height of salinity and water temperature. If the results were combined with another micro and macro mineral analysis will to become the basic for estimating the status of seagrass fertility.

Abstract

Pterospermum subpeltatum C.B. Rob or bayur is traditionally and widely used as medicine for infection diseases caused by bacteria. Four extract from root stem of this plant were evaluated for their antibacterial activity properties against Escherichia coli, Shigella boydii, staphylococcus aureus dan Streptococcus mutan. All the extract were able to inhibited the bacterial strain except Staphylococcus aureus. Chloroform extract exhibited effect for   Shigella boydii and Streptococcus mutan. Hexana extract for Escherichia coli, while methanol extract for Shigella boydii. All extract showed an effect at the same extend (MIC; 50 mg/ml).
