Analisis Merek, Promosi dan Harga Pengaruhnya terhadap Keputusan Pembelian di Gelael Swalayan Manado

Era globalisasi menjanjikan suatu peluang dan tantangan bisnis baru bagi Perusahaan yang beroperasi di Indonesia. Di tengah persaingan yang semakin ketat, banyak Perusahaan menerapkan berbagai macam strategi untuk menarik konsumen agar mau melakukan pembelian. Masing- masing Perusahaan harus memiliki strategi untuk memenangkan konsumen dan dapat bertahan di tengah ketatnya persaingan. Penelitian ini bertujuan untuk mengetahui pengaruh analisis merek, promosi dan harga terhadap keputusan pembelian pada gelael swalayan di kota manado. Sampel penelitian diambil sebanyak 98 responden. Metode penelitian yang digunakan adalah asosiatif. Teknik analisis data yang digunakan adalah analisis regresi linear berganda. Hasil penelitian menunjukkan bahwa secara bersama variabel merek, promosi, dan Harga berpengaruh positif dan signifikan terhadap keputusan pembelian konsumen. Secara parsial Variabel merek berpengaruh positif namun tidak signifikan terhadap keputusan pembelian. Variabel promosi dan harga berpengaruh positif dan signifikan terhadap keputusan pembelian. Sebaiknya manajemen Gelael Swalayan lebih meningkatkan strategi pemasaran yang dianggap dapat mempertahankan posisi Perusahaan di era persaingan ritel yang sangat ketat di kota Manado saat ini. Kata kunci: analisis merek, promosi, harga, keputusan pembelia

Rotational study of 67P/Churyumov-Gerasimenko

International audienceThe aim of the study is to determine the gravity field and moments of inertia along the principal axes of the comet, the obliquity of the axis of rotation with respect to the mean orbital plane, the precession rate, and the nutation coefficients. We also investigate the role of relevant parameters on the rotation

Spheroidal forward modelling of the gravitational fields of 1-Ceres and the Moon

A novel, explicit, and efficient forward modelling of the spheroidal harmonic spectra of external planetary gravitational fields is developed in this article. We introduce the oblate spheroidal coordinate system and derive the mathematical apparatus for the analysis of the spheroidal harmonic spectrum from the volumetric bulk density and geometry of a gravitating body. We discretise the volume integral and formulate a new and efficient numerical algorithm for the spheroidal forward modelling. We provide complete sets of recursions for calculating the associated Legendre functions of the first kind and their integrals in the Supplementary material. We also develop a computer program that implements the numerical algorithm and we test its performance. For this purpose, we consider synthetic gravitational fields of 1 Ceres (a significantly flattened asteroid) and of the Moon (a nearly spherical body). These tests prove high numerical accuracy and applicability of the spheroidal forward modelling up to degree and order 2519. We finally apply our spheroidal forward modelling and its simpler spherical counterpart for computing global gravitational field models up to degree and order 2519 generated by realistic topographic mass distributions of 1 Ceres and of the Moon. These models are compared in the spatial and spectral domains to manifest an enhanced applicability of the spheroidal approach with respect to the spherical one. In particular, we show an extended convergence space when using the spheroidal forward modelling and the corresponding harmonic representation for the oblate 1 Ceres
