UJI ALAT DINAMIKA PROSES DENGAN VARIABEL ORDE DUA NON INTERACTING (TEST THE DYNAMICS OF THE PROCESS TOOL WITH A SECOND ORDER NON-INTERACTING VARIABLES)

The dynamics of the process is something that occurs in a system, with the rapid process variables change with the opening control valve. On the dynamics of the process qualitatively capacity and delays are used as standard (size), while the transfer fuction is expressed asa a standard dor quantitative dynamics process. On the order of two non-interacting, the second levelin the tank will not affect the size of the flow rate out of the first tank. As in the first order, second order transfer fuction process non-interacting is also a function of the differential equation of time. The larger the aperture control valve in each tank, teh higher the altitude level. Keyword : dynamics of the process, order two non-interacting, control valv

ELEKTRODEKOLORISASI LIMBAH CAIR INDUSTRI KAIN TENUN MENGGUNAKAN ELEKTRODA PbO2/Pb

Telah dilakukan penelitian tentang elektrodekolorisasi limbah cair industri kain tenun dengan elektroda Pb02/Pb. Penelitian dilakukan dengan mengelektrolisis sampel limbah cair industri kain tenun pada potensial 5,0 volt. Media elektrolisis zat warna adalah air limbah industri kain tenun sedangkan elektroda yang digunakan adalah PbO2-Pb serta pengaturan waktu elektrolisis selama 90 menit. Hasil akhir elektrolisis dianalisis secara kualitatif dan kuantitatif dengan Spektrometer UV-Vis dan analisis produk terhadap nilai total dissolved solid (TDS) dan kekeruhan. Hasil yang diperoleh menunjukkan elektrolisis air limbah industri kain tenun menggunakan elektroda PbO2-Pb menghasilkan dekolorisasi sebesar 98,8%, penurunan nilai total dissolved solid (TDS) sebesar 96,05% dan kekeruhan sebesar 99,90

On the smallest Laplace eigenvalue for naturally reductive metrics on compact simple Lie groups

Eldredge, Gordina and Saloff-Coste recently conjectured that, for a given compact connected Lie group $G$, there is a positive real number $C$ such that $\lambda_1(G,g)\operatorname{diam}(G,g)^2\leq C$ for all left-invariant metrics $g$ on $G$. In this short note, we establish the conjecture for the small subclass of naturally reductive left-invariant metrics on a compact simple Lie group.Fil: Lauret, Emilio Agustin.

Phenomenology of a SU(2) triplet Higgs.

We study the Renormalization Group (RG) evolution of the couplings in a model with a real SU(2) triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV we show that it is possible for there to be no light Higgs bosons without any otherwise dramatic deviation from the physics of the Standard Model

STUDI PEMBUATAN TABLET EFFERVESCENT DENGAN MENGGUNAKAN EKSTRAK BUNGA MAWAR MERAH (Rosa damascena Mill.) (Kajian Warna Bunga dan Jenis Gula)

Rose is one of the farming products that used as an accessory plantation. The sheath is also known consists of Vitamin C and the antosianin pigment which it is also categorized as flavonoid, and it used as a free radical protector (antioxidant). The functioning of the sheath as a medicine is also consumed in drinks, which is produced from the rose extract or in effervescent tablets. The purpose of this study is to identify the color effect of flower through the effervescent tablet’s quality, to know the interaction between the flower’s color and the kinds of sugar through the effervescent rose tablet’s quality. The hypothesis of this study is, it was suspected that the color of the flower influenced to the quality of the rose’s pigment, suspected that there was an interaction between the qualities of the rose effervescent rose drinks. This study done with two steps, those were: At the step I, with 2 levels of examinations, by using Simple Random: Rose coloring, M1 (dark red) and M2 (pink), while the second factor consisted of three levels of examinations, those were G1 (sucrose), G2 (dextrose), and G3 (Tropicana slim), and they were repeated three times. The result showed that at the act of the dark red color has a better extract pigment quality, the level of the light color was (L) 77,3 and the redness level was (b+) 25,033. The best rose effervescent tablet was produced by the combination of M1G3 (dark red:Tropicana slim),, which has 8,179% sense of water; the level of hardness was 11,5kg/cm2; the speed of protracted was 0,029 g/dt; the level of the lightness was (L) 84,133, the level of the redness was (a+) 18,3 and the level of yellowness was (b) 2,733. At the product of the rose effervescent drinks has a value of 6,46 pH; viscosities 342,867 cps; total of hardness 0,814 g/g and total of sugar 52,150%
