The adsorption of Cr (III) using silica gel from rice husk ash modified with diphenilcharbazon ligand (Si-DPZon) was investigated.The aim of this study was to determine the optimum pH and contact time, the pattern of adsorption isotherm as well as the type of interaction between metal ion and the silica gel through sequential desorption. The result showed that the silica gel resulted has a surface acidity (Kal) of 0.1046 mmol/g and number of active sites of 17,9672 x 1020 atoms/gram. The adsorption optimum pH is 3.0 with the optimum contact time of 30 minutes where the Cr(III) adsorbed is 24,5047 mg/g. The adsorption follows the Freundlich isotherm. Interaction that occurs between the Cr (III) and the Si-DPZon adsorbent is dominated by physical interaction.

Identification of antifeedant active compounds from Soursop seeds (Annona muricata Linn) as natural pesticides against Plutella xylostella has been carried out. 1800 g Soursop seed powder maceration was applied using methanol and n-hexane resulted in 46.42 g extract of methanol and 94.19 g extract of n-hexane. Viscous extract of methanol was diluted with the mixture of methanol:water (7:3), then evaporated until the entire methanol was removed, and after that it was partitioned with chloroform. The antifeedant activity of viscous extract of n-hexane, chloroform and water was tested which showed that the extract of n-hexane had highest activity compared to the others. Separation of 2 g viscous n-hexane extract with Coloumn Chromatography using Gel Silica 60 and n-hexane:aceton (4:1) as the mobile phase resulted in 5 fractions. The fractions were tested against Plutella xyllostella. The results showed that fraction C had the highest antifeedant activity. The isolate of fraction C was then identified using Gas Chromatography-Mass Spectrometry (GC-MS) based on the data base (Database\NISTO2.L and Database\wiley7n.1) suggested the active compounds were ethyl hexadecanoate ester and 11-octadecanoic acid.

Phytochemical screening and antioxidant activity test of the ethanol extract of eggplant fruit (Solanum melongena L) have been done. Extraction is done by maceration method using ethanol. Phytochemical screening is done by testing the qualitative class of antioxidant compounds such as alkaloids, flavonoids, tannins, saponins, glycosides, anthraquinone, and steroids / triterpenoids. Phytochemical screening results indicate the presence of alkaloids and flavonoids. Test of the antioxidant activity of the ethanol extract of eggplant fruit with DPPH method using UV-Vis spectrophotometer resulted the DPPH antioxidant activity optimum in 29th minute and the 58th minute with a maximum wavelength of DPPH solution of 513 nm. Testing the power of antioxidants compared to ascorbic acid as a positive control showed by IC50 of 535.89 ppm in 29th minute and 385.06 ppm in 58th minute.

Mangosteen rind is a valuable waste, rich in saponins, xanton, and tannin. Liquid soap was made by saponification reaction of ethanol extract of mangosteen rind and fats are reacted with KOH. This study aims to perform the optimization of liquid soap formula and determine its physical and chemical properties. Extract of mangosteen (Garcinia mangostana L.) obtained by maceration for 3 days with 70% ethanol, and vaccuum evaporated. Liquid soap was prepared by heating method for ± 3 hours. The evaluation consists of organoleptic test, pH, and specific gravity determination. The results show that the liquid soap from 2% ethanol extract of mangosteen rind is dark brown, homogenous liquid, has a characteristic odor and specific gravity between 1.022 to 1.036 g / ml, and pH between 12.16 to 12, 92. From the test results, liquid soap formulas which meet commercial criteria are formula V and VI.

Cr and Zn contents in the roots, trunks and leaves of the Rhizophora apiculata in estuary of Badung river have been investigated. This study was aimed to determine the ability of Rhizophora apiculata in accumulating heavy metals from the ecosystem. The concentrations of Cr and Zn in the water, sediments, roots, trunks and leaves were determined by the use of Atomic Absorption Spectrophotometer. The results showed that the highest concentrations of both Cr and Zn were found in leaves of the Rhizophora apiculata. Total Cr dan Zn concentrations in the roots were 2,49±0.19 and 19,4 ± 0,06 mg/kg respectively and in the trunks were 3,26 ± 0,28 and 4,14±0,32 mg/kg respectively, while in the leaves were 4,45 ±0,07 and 38,72 ±0,03 mg/kg respectively. The water and sediment contents of the metals were reported separately, and they were much lower than those in the plant samples. Upon comparing these values, it can be suggested that the Rhizophora apiculata was capable of accumulating heavy metals present in its environment.

Leaves of pangi (Pangium edule) are known to have many benefits, including antifeedant activity. 500 g of pangi leaf powder was extracted by maceration method using n-hexane extract yieled 4.51 g of dark green extract. This extracts showed high antifeedant activity (47.23%) against Plutella Xylostella at a concentration of 0.1% (w / v). Separation of 2 g of n-hexane extract by chromatography column using n-hexane: ethyl acetate: chloroform (6:2,5:1,5) as mobile phase and silica gel 60 as stationary phase produced 6 groups of fractions. Fractions 3 reveiled the highest antifeedant activity that is 52.15%, 69.88%, and 91.66% respectively at a concentration of 10 ppm, 100 ppm, and 1000 ppm. This active fraction which was considered relatively pure following purity test on TLC was then identified using GC-MS spectrometre. GC-MS spectra of antifeedant active compound contained at least 11 compounds with 8 compounds successfully identified as ? – pinene, benzene trimethyl, acetic acid triflouro-tetradecyl ester, nonadecene, 13-Hexyloxacyclotridec-10-en-2-one, phytol, 3-eicosene, , benzenedicarboxylic acid diisooctyl este.

Metal concentration in water enviroment and sediment cannot give sufficient information about bioavailability of those metals in the waterworks. The aims of this study are to determine the bioavailability and specification of Cu and Zn in water enviroment and sediment in the estuary of Badung river in the “Taman Hutan Raya Ngurah Rai” Denpasar, Bali area. Determination of bioavailability and speciation of those metals were accomplished by sequencial extraction method. The results of this study show that total concentrations of Cu, and Zn in the water samples are 0,1792 mg/L, and 0,0647 mg/L. The sum of the fraction of non-resistant and resistant fractions of Cu and Zn in the sediment obtained in this study indicates the total concentration of metals in the sediment, i.e 33,9036 mg / kg and 50,8296 mg/kg. Results of the metal speciation are as follow: fraction of Cu is dominated by resistant fraction that is 64,38 %, whereas non-resistant fractions are: 3,70 % for acid reducible and 31,89% for oxidisable organic. Fraction of Zn is dominated by acid reducible fraction of 39,27 %, followed by organic oxidisable of 25,46 % and EFLE fraction of 1,80%, whereas the resistant fraction is 33,47 %. The percentages of Cu and Zn bioavailabilities respectively are 35,59 % ; and 66,53 %.

Induction of apoptosis and antiangiogenesis effects of Pinostrobin from Kaempferia pandurata Roxb against Fibrosarkoma mice induced with benzopiren have been investigated. Examination begins with taking tissue of fibrosarcoma in mice infected and weighing the fibrosarcoma obtained. Fibrosarcoma tissues were then stored in 10 % formalin. Weighing results showed that pinostrobin oral concentration of 80 mg/kg can inhibit 68.62 % growth of fibrosarcoma. It was also shown that cancer drug (positive control) resulted in 95.95 % inhibition compared to the negative control. This means pinostrobin can potentially be developed as a cancer chemotherapy drug. Patohystology analysis of the fibrosarcoma tissue with HE staining on light microscope with 400x magnification showed many chromatins (polychromatin) which proved the damage caused by the fibrosarcoma cells.
