This research aimed to identify the antioxidant capacity, vitamin C (ascorbic acid), and total phenolic compounds of frangipani flower powder. The powder was extracted using ethanol, methanol, acetic acid, and water (aquadest). Antioxidant capacity of each extract were determined using 2,2-diphenyl-1-picrylhydrazyl radical scavenging method, vitamin C were determined using 2,4 Dinitrophenylhydrazine, and total phenolic compounds were determined using Folin Ciocalteu reagent. All of parameters were measured by spectrofotometer. The result shows that the highest value of antioxidant capacity was ethanolic extract (18.19%) and the lowest value was acetic acid extract (12.74%). The highest value of vitamin C was aqueous extract (3.49 mg/100g) and the lowest value was acetic acid extract (3.02 mg/100g). The highest value of total phenolic content was aqueous extract (25.49 mg GAE/g) and the lowest value was acetic acid extract (22.74 mg GAE/g). In conclusion, the higher antioxidant capacity was not always followed by the higher of vitamin C and total phenolic compounds.

Hypercholesterolemia or hyperlipidemia has been established as an important risk factor of cardiovascular disease. Patients with hypercholesterolemia usually require a prolonged treatment; and the newer and more potent generation of antilipid agents are costly.In Bali there are several types of seaweed that are generally consumed by the local people and known by the local names of Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.). Preliminary studies on the effect of Bulung Boni and Bulung Sangu extracts appeared to improve lipid profile, but the available data are still very limited both in extent and depth, and further investigations were considered relevant and needed.This experimental study used completely blind randomized design, using a total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol content. The six sample groups were respectively designated as negative control group, positive control group, and four treated sample groups, respectively fed orally with a dose of 20 mg and 60 mg extracts of Bulung Boni per 100g of body weight per day, and 20 mg and 60 mg extracts of Bulung Sangu per 100g body weight per day. Each treatment was repeated four times.Our study showed that rats fed with high-cholesterol diet and treated with oral Bulung Boni or Bulung Sangu extract at a dose of 20 mg and 60 mg/100 g bw/ day were associated with statistically significantly increased plasma HDL levels (p < 0.05), and statistically significant decreased plasma LDL and total cholesterol levels (p < 0.05) as compared with those of rats fed with high cholesterol diet without treatment with Bulung Boni or Bulung Sangu extracts.From our data it could be implied that Bulung Boni and Bulung Sangu extracts improve lipid profile in the Wiatar rat by significantly increasing plasma HDL level, and lowering LDL and total cholesterol levels.

In the volcanic devastated site of Mt. Batur located in the north eastern part of Bali, Indonesia,the test construction with the soil protection sheet and the bag material for the prevention of soilerosion and the revegetation had been executed in December, 2012 and the effect has beenverified by now. In this study, the effect of the sheet on the soil microorganisms was investigatedand the effect of the indigenous arbuscular mycorrhizal fungi, which had been put into the bagmaterial with 3 kinds of woody plant seeds, on the vegetation was verified. As a result, after 2years and 8 months from the construction, it was showed that the soil microorganisms under thesheet without the plant increased 2 to 2.4 times more than those in the bare site without the plant.Furthermore, those soil microorganisms under the sheet with the plant increased 8.4 to 8.9 timesmore than those in the bare site without the plant. It is considered that the cutting fragments in thelength of about 5cm of the gramineous plant root existed near the construction site put into thebag material with the woody plant seeds contributed to the colonization of the arbuscularmycorrhizal fungi into the roots of seedlings from the seeds and the survival of the seedlings fromthe seeds as the inocula of the fungi.

The purpose of this study was to know the effectiveness of Gracilaria sp. ethanol extract to inhibit the growth of Aspergillus niger. The results showed that the ethanol extract of Gracilaria sp. was not effective to inhibit the growth of A. niger. The minimum inhibitory concentration test (MIC) was carried out using extracts with 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7 %, 0.8 %, 0.9%, 1%, 2% and 0% percentage. The MIC results showed that the minimum extract inhibiting A. niger was 0.8%. The results of the antifungal activity test showed that the ethanol extract of Gracilaria sp. was fungistatic against A. niger. On the third day incubation, the 4% extract inhibited the growth of fungi with an average diameter of 5 mm. The fungal colony test was carried out using extract with 0.5%, 1%, 2%, 4% and 0% concentration, and the results showed that extract with 4% concentration can inhibit fungi colony growth by 69%. Phytochemical analysis was conducted using the UV-Vis Spectrophotometry, and the results showed that the ethanol extract of Gracilaria sp. contained 366.33 mg/100g/GAE phenol, 2041.47 mg/100g flavonoids, and 3041.60 mg/100g/TAE tannins. Tannins are suspected to be the most dominant fungistatic compound with the largest amount.

Citrus Vein Phloem degeneration (CVPD) is the most important disease and a major cause of yield loss citrus plantations in almost all countries, especially Asia and Africa. CVPD disease is caused by gram negative bacteria, Liberobacter asiaticum L. Pathogens can not be cultured in vitro, but can be detected by PCR using 16S rDNA fragment as a primer and by electron microscopy. The use of PCRusing specific primer pair can detect infected plants more accurately. Citrus plant that infected by CVPD disease contain a very specific protein that produced by the pathogen. The specific protein molecules can be detected by comparing the protein bands of infected citrus plants and the healthy one which have molecular weight of approximately 16 kDa and 66 kDa, whereas in healthy citrus plant that protein molecule was not found.
