    Indonesia adalah negara tropis yang memiliki keanekaragaman hayati beragam. Sebanyak 7.500 tumbuhan termasuk tumbuhan obat, salah satunya yaitu bunga telang. Bunga telang (Clitoria ternatea) atau yang dikenal juga dengan polong kupu-kupu dan bunga biru merupakan salah satu jenis tumbuhan liar dan tumbuh merambat yang belum banyak dimanfaatkan masyarakat. Skrining fitokimia Clitoria ternatea mengandung total fenol yang jauh lebih tinggi dibanding total antosianin. Senyawa fenol merupakan kunci dari sifat antioksidan dari ekstrak tumbuhan. Penelitian akan total fenol dan aktivitas antioksidan bunga telang sebagian besar menggunakan ekstrak hasil ekstraksi konvensional. Penggunaan kekuatan ultrasonik secara signifikan meningkatkan pemisahan fenolat dan kapasitas antioksidan ekstrak sekaligus mengurangi waktu ekstraksi dan meningkatkan efisiensi energi. Faktor yang mempengaruhi proses ekstraksi dan kecepatan rambat gelombang ultrasonik diantaranya waktu dan jenis pelarut yang digunakan. Penelitian dilakukan menggunakan metode Rancangan Acak Kelompok (RAK) yang disusun secara faktorial dengan faktor pertama adalah jenis pelarut yang terdiri atas tiga level yaitu etanol 96% (P1), metanol (P2), aseton (P3) dan faktor kedua adalah waktu ekstraksi yang terdiri atas tiga level yaitu 20 menit (T1), 30 menit (T2), 40 menit (T3). Masing-masing dulang 3 kali, sehingga didapatkan 27 unit percobaan. Setiap sampel diuji rendemen, kadar air, kandungan total fenol dengan metode Folin-Ciocalteu, dan aktivitas antioksidan dengan metode DPPH. Penentuan perlakuan terbaik menggunakan metode Multiple Attribute. Koefisien transfer massa (kLa) dihitung untuk membandingkan efisiensi masing-masing perlakuan. Hasil penelitian menunjukkan total fenol ekstrak bunga telang tertinggi adalah 126,176mg GAE/g pada pelarut metanol 30 menit. Aktivitas antioksidan ekstrak bunga telang tertinggi dengan nilai IC50 paling rendah adalah 35,835 ppm pada pelarut metanol 20 menit. Aktivitas antioksidan meningkat sejalan dengan mengkatnya kandungan total fenol, dimana keduanya memiliki hubungan kuadratik terhadap waktu ekstraksi dengan pengaruh sebesar 0,7465 atau 74,65%. Perlakuan terbaik adalah pelarut metanol dan waktu ekstraksi 30 menit dengan nilai masing-masing parameter diantaranya rendemen fenol 3,081%; total fenol 87,059 mg GAE/g; dan IC50 35,835 ppm. Koefisien transfer massa (kLa) yang pada ekstraksi bunga telang (Clitoria ternatea) dengan pelarut etanol adalah sebesar 0,0366, metanol sebesar 0,0381, dan aseton sebesar 0,033

    Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

    Get PDF
    The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

    Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

    The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration

    Observation of associated near-side and away-side long-range correlations in √sNN=5.02  TeV proton-lead collisions with the ATLAS detector

    Get PDF
    Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

    Search for R-parity-violating supersymmetry in events with four or more leptons in sqrt(s) =7 TeV pp collisions with the ATLAS detector

    Get PDF
    A search for new phenomena in final states with four or more leptons (electrons or muons) is presented. The analysis is based on 4.7 fb−1 of s=7  TeV \sqrt{s}=7\;\mathrm{TeV} proton-proton collisions delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in two signal regions: one that requires moderate values of missing transverse momentum and another that requires large effective mass. The results are interpreted in a simplified model of R-parity-violating supersymmetry in which a 95% CL exclusion region is set for charged wino masses up to 540 GeV. In an R-parity-violating MSUGRA/CMSSM model, values of m 1/2 up to 820 GeV are excluded for 10 < tan β < 40
