Get PDFNipah or Nypa fruticans Wurmb is a member of the Palmae tribe that lives in the Mangrove ecosystem and is known to have rich bioactive sources, one of which is antioxidants. The ability of N. fruticans as an antioxidant is also possible for endophytes associated with N. fruticans. This study aims to obtain endophytes that live in N. fruticans leaf tissue and find out their ability as antioxidant agents using synthetic free radicals 2.2 diphenil-1-pikrilhidrazil (DPPH). Samples taken at Nipah Panjang Tanjung Jabung Timur, Isolation and production were carried out at the Jambi University Faculty of Science and Technology Engineering and Biotechnology Laboratory, absorbance measurements using UV-VIS at λ 517 nm at the Jambi University CRC. The antioxidant activity of isolates was shown from the value of Inhibitor Concentration (IC50) which caused 50% loss of DPPH free radicals. From the results it was obtained that the six isolates (DN01, DN02, DN02, DN03, DN04, DN05, and DN06) value the antioxidant activity of endophytic extracts lower than vitamin C activity and still classified as weak. Even though endophytic Nypa fruticans are very weak, N. fruticans endophytic in all treatment concentrations still have the ability as antioxidants and optimization methods are needed to get good antioxidant values.

Get PDFAbstractPagaralam is one of the tomato suppliers for the South Sumatera region. Tomatoes are often attacked by pests such as aphids. Aphids fleas (Aphid sp.) are one of the main pests besides that aphids are important vectors that can transmit viral disease. The use of chemical insecticides can damage agricultural land for the use of vegetable insecticide alternatives. Alkoloid, Flavoid, Saponin, and Tanin contained in papaya leaves (Carica papaya) can be used as a plant aphid insecticide. The sample in this study was a 2 month old tomato plant with 20 aphids in each tree. Treatment was given to 5 treatment with 5 replications. This treatment by giving different concentrations of papaya leaf solution in the crop of 0%, 15%, 30%, 45%, and 60%. To determine the effectiveness of papaya leaf solution (Carica papaya) as a vegetable insecticide aphid done spraying as much as 100 ml once spray with contact time observation 12 hours and 48 hours. The results showed that the application of papaya leaf juice was effective in killing aphids, so that high concentrations that gave greater precentage of aphids deaths ranged from 24 hours showed F count > and F table and received at level 1% means that papaya leaf juice was very influential on aphids death. Then the results of cofactor coefficient (KK) 24 hours and 48 hours were 10% and 4%, before using The Smallest Significant Difference Test (BNT) to see the effect of each concentration. BNT Test pre view, each concentration was very significant which had a different effect on the death of ticks to analyze probit LC50 to determine the effective concentration of killing 50% of the samples at 39,81%.
