    The purpose of the study was to determine the marketing channels, marketing margin, part of the price received by farmers and marketing efficiency. Determination of the respondents to the farm was done intentionally (purposive). Total respondents two people consisting of 1 leader and 1 employee with the consideration that the respondents have to know the flow of the marketing of the products produced. Respondent traders used assessment method (Tracing Method), in order to obtain each 2 collectors and 1 retailers. The results showed that there are two channels of marketing eggs in the effort "breeder laying hens on the farm" Aris Light Sweet "as follows: 1). Breeders - Traders Gatherer - Retailer - Consumer. 2). Breeders - Traders Gatherer/retailer - Consumer. Margin on the first channel of IDR.9,600 and a second channel IDR.5,400. Section prices received by farmers in the first marketing channel by 91% and the second channel by 93%. Section prices received by farmers on the second channel ar greater, with the efficiency of 4,5%. Compared with the first channel with the efficiency of 4,7%. The results also showed that the efficiency of the marketing channels more efficiently

    The research objective ( Analysis the behavior of the price of palm oil CPO (Crude Palm Oil ) on PT. Pasangkayu company . The research was conducted on the Company PT.Pasangkayu December 2014- February 2015. The data analysis is simple regression and correlation analysis . The results of the analysis of price changes cpo in world prices by using simple regression analysis obtained my value = -1.02 + 1,22mx coefficient is real. this is indicated by thitung ( 19.89 ) > t table ( 3.012 ) with a value of 0.000 < 0.01 level of α = 1 % , that the changes in the world price for 1 exchange rate causes changes in the price of the company amounted to 1.22 rate level . correlation analysis is Y and X = 0.991 P -Value = 0.000 , analysis showed that changes in the level of the world price level cpo prices very influential company real

    Quasilinearization Method and Summation of the WKB Series

    Full text link
    Solutions obtained by the quasilinearization method (QLM) are compared with the WKB solutions. Expansion of the pp-th QLM iterate in powers of \hbar reproduces the structure of the WKB series generating an infinite number of the WKB terms with the first 2p2^p terms reproduced exactly. The QLM quantization condition leads to exact energies for the P\"{o}schl-Teller, Hulthen, Hylleraas, Morse, Eckart potentials etc. For other, more complicated potentials the first QLM iterate, given by the closed analytic expression, is extremely accurate. The iterates converge very fast. The sixth iterate of the energy for the anharmonic oscillator and for the two-body Coulomb Dirac equation has an accuracy of 20 significant figures

    Analytic calculation of energies and wave functions of the quartic and pure quartic oscillators

    Full text link
    Ground state energies and wave functions of quartic and pure quartic oscillators are calculated by first casting the Schr\"{o}dinger equation into a nonlinear Riccati form and then solving that nonlinear equation analytically in the first iteration of the quasilinearization method (QLM). In the QLM the nonlinear differential equation is solved by approximating the nonlinear terms by a sequence of linear expressions. The QLM is iterative but not perturbative and gives stable solutions to nonlinear problems without depending on the existence of a smallness parameter. Our explicit analytic results are then compared with exact numerical and also with WKB solutions and it is found that our ground state wave functions, using a range of small to large coupling constants, yield a precision of between 0.1 and 1 percent and are more accurate than WKB solutions by two to three orders of magnitude. In addition, our QLM wave functions are devoid of unphysical turning point singularities and thus allow one to make analytical estimates of how variation of the oscillator parameters affects physical systems that can be described by the quartic and pure quartic oscillators.Comment: 8 pages, 12 figures, 1 tabl

    Kelayakan USAhatani Kakao di Desa Sidondo IV Kecamatan Sigi Biromaru Kabupaten Sigi

    Penelitian ini bertujuan untuk mengetahui kelayakan USAhatani kakao di Desa Sidondo IV, Kecamatan Sigi Biromaru, Kabupaten Sigi. Penentuan sampel dilakukan secara sengaja (Purpossive) dengan pertimbangan bahwa Desa Sidondo IV merupakan salah satu daerah penghasil Kakao di Kecamatan Sigi Biromaru yang produksinya sebesar 15.532. Responden merupakan petani kakao.Alat analisis yang digunakan adalah Analisis PAM (Policy Analysis Matrix). Hasil penelitian menunjukkan kelayakan USAhatani kakao di Desa Sidondo IV, hal ini ditunjukan oleh nilai finansial lebih besar dari pada nilai sosial yang artinya keuntungan finansial pada USAhatani kakao di Desa Sidondo IV adalah Rp.11.677,175 sedangkan keuntungan sosial Rp. 11.423,918. Hal ini terjadi karena harga input tradable yang dibayarkan atau diterima petani tidak sesuai dengan apa yang diinginkan oleh petani. Apabila nilai finansial lebih besar dari pada nilai sosial maka USAhatani dalam posisi yang menguntungkan, dan kelayakan Usaha tani di Desa Sidondo IV, berdasarkan analisis PAM menunjukan nilai komperatif sehingga USAtahani kakao di Desa Sidondo IV layak untuk di USAhakan oleh petani-petani kakao di desa tersebut
